The open parts 107 and 114 are caught on the side surface of the body, and the workability is deteriorated. In order to prevent this catching, the hand must be separated from the side of the body, and if this posture is maintained for a long time, fatigue tends to occur.

On the other hand, in order to improve the balance of the spray pipe 100 to be operated, the screw 108 is loosened and the semicircular portion 10 is loosened.
5, 106 or the semicircular portions 112, 113 are moved together with the spray pipe handle 101 to a desired position along the longitudinal direction of the spray pipe 100, and adjustment work for tightening the screw 108 at a balanced position is required. A tool must be available to turn the screw 108. If a screw with a knob is used instead of the screw 108, the expansion portions 107, 114
Since the protruding length of the right side of the body becomes longer, the hand is separated from the side surface of the body, workability further deteriorates, and fatigue increases.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes a flexible spray pipe connected to a blower port of a sprayer main body (not shown). The distribution pipe handle 2 fixed to a part of the outer periphery of the distribution pipe 1 has two divided covers 3 and 4. As shown in FIG. 3, the spray tube handle 2
Is provided with a throttle lever 6 which rotates about a support shaft 5. 7 is a throttle cable whose one end is fixed to the throttle of the engine of the spreader body (not shown),
The throttle cable 7 is covered with a flexible outer cable 8.

As shown in FIG. 1, a pair of handle mounting bodies 9 and 10 for holding the spray pipe 1 are provided.
These handle mounting bodies 9 and 10 are each provided with a curved portion 11 that is defined in a semicircular shape and is elastically bendable, a connecting portion 12 that is continuous with one end of the curved portion 11, and a curved portion 11. It consists of columns 13 and 14 that are continuous at the ends. One of the columns 13 has a large wall thickness, and a metal insert (not shown) is embedded in the column 13 to enhance the rigidity. The wall thickness of the other pillar 14 is set to be thin. Further, in a state in which the pair of handle mounting bodies 9 and 10 face each other and surround the spray pipe 1, the four columns 13 and 14 are arranged such that the columns 13 and 14 of the one handle mounting body 9 are opposite to each other. The columns 14 and 13 are arranged so as to face each other with a slight gap therebetween. Further, a through hole 17 into which a knob screw 16 having a knob 15 at one end is inserted is formed in each of the columns 13 and 14, and a commercially available nut 18 is fitted to the outer surface of the column 14 having a smaller wall thickness. A hexagonal recess 19 to be fitted is formed. Reference numeral 20 is a screw for connecting the connecting portion 12.

As shown in FIG. 2, a rectangular opening 21 into which the four support columns 13 and 14 are covered and fitted is formed at the base end of the spray pipe handle 2, and the rigidity is high. A mounting hole 22 through which the knob screw 16 is inserted is formed so as to face the outer surface of the other column 13.

In such a structure, the pair of handle mounting main bodies 9 and 10 are opposed to each other with the spray pipe 1 in between, and the connecting portions 12 of the both are joined by the screw 20 to form the recess 19 of the column 14.
The nut 18 is fitted to the four, and the four columns 13 and 14 are fitted to the opening 21 of the spray tube handle 2, and the screw 16 with a knob is attached from the mounting hole 22 of the spray tube handle 2 to the through hole 17 of the columns 13 and 14. Through, and turn the knob 15 to screw the knob screw 16 into the nut 18. As a result, the thin column 14
Is attracted to the side of the column 13 having high rigidity, and the spray tube 1 is held by the pair of handle mounting bodies 9 and 10. At the same time, the handle mounting bodies 9 and 10 and the spray pipe handle 2 are joined.

In this case, the knob 15 of the screw 16 with the knob presses the outer side surface of the spray tube handle 2, but the knob 15

Is moved to a desired position together with the spray pipe handle 2 and the screw 16 with knob is tightened. In the state where the screw 16 with knob is loosened,
Since the pair of handle mounting bodies 9 and 10 can be elastically deformed to separate the support columns 13 and 14 from each other, in order to move the handle mounting bodies 9 and 10 along the spray pipe 1, the connecting portion 12 It is not always necessary to loosen the screw 20 for connecting the. Further, since the knob screw 16 can grip and rotate the knob 15, it is not necessary to always have a tool such as a driver. In addition, when making adjustments outdoors,
Since the nut 18 is fitted in the recess 19 of the column 14 and covered by the spray pipe handle 2, it does not fall off and become lost. It should be noted that the pair of handle mounting bodies 9 and 10 is the support 1
Since one end on the 3 and 14 side is firmly connected, the connecting portion 12
The structure is not limited to the structure in which the screw 20 is used for connection, and may be a structure in which the recess and the projection are detachably engaged with each other. As a result, no tools are required for the work of assembling the handle mounting bodies 9 and 10 and the spray pipe handle 2 to the spray pipe 1.

When the spraying agent is sprayed, the engine is started and the sprayer main body is carried on the back of the spraying tube handle 2 with one hand.

Then, in the usage pattern in which the spray pipe handle 2 is gripped and the spray pipe 1 is suspended, the connecting portion 1 for connecting the pair of handle attachment main bodies 9 and 10
Since the 2 and the columns 13 and 14 are positioned in the vertical direction with the spray pipe 1 in between, the width of the handle mounting bodies 9 and 10 is narrowed when viewed from the vertical direction, and the handle mounting bodies 9 and 10 are The smooth side surface (curved portion 11) can be directed to the side surface of the human body. This makes it possible to maintain a comfortable posture in which the hand holding the spray tube handle 2 is brought close to the side surface of the human body. Therefore, fatigue can be reduced even if the spraying work is continued for a long time.

As shown in FIGS. 6 and 7, the width of the column 13 having a higher rigidity is set to the opening 21 of the spray tube handle 2.
The width may be set to be equal to the inner width of the, and a storage portion 23 for storing the thin column 14 may be formed at the end opposite to the knob 15. With such a configuration, the screw 16 with knob
When the spray tube 1 is clamped by the pair of handle mounting bodies 9 and 10, the pillar 14 having a thin wall is attracted to the side of the pillar 13 having high rigidity and is separated from the inner surface of the opening 21 of the spray tube handle 2. However, since the inner surface in that portion can be supported by a part of the highly rigid column 13,
Even if the wall surface around the opening 21 receives an external force, it does not dent.
