Is provided, and the projection 7 moves on the ground where grasses and the like are growing at the time of cutting to support the cutting machine.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protector for a trimmer, which protects a worker from branches and the like scattered during cutting work.

[0002]

[Prior Art]

 The conventional protector 14 for a trimmer is fixed to the main body 3 via a screw 16 rotated by a driver as shown in FIG. 8, and protects an operator from scattering of cut branches.

[0003]

[Problems to be solved by the device]

 The conventional protector 14 for a trimmer has a problem that it is difficult to maintain a constant trimming height because the trimmer body 3 is held by both hands when performing a mowing operation of turf grass, for example. It was The object of the present invention is to reduce the operator's tiredness due to holding, while the cutting height can be adjusted arbitrarily to perform a constant cutting.

[0004]

[Means for Solving the Problems]

 The purpose of the above is to form a long hole for adjusting the trimming amount on the side wall of the protector's attachment to the trimmer, and to form a semicircular protrusion on the bottom of the protector that can move smoothly on the ground such as grass. Achieved by.

[0005]

[Action]

 As described above, the protector having the elongated hole and the protrusion is moved up and down along the elongated hole provided in the fitting portion between the trimmer main body and the protector with the fixing bolt as an axis, Also, when cutting grass, etc., semi-circular protrusions are used for the front, rear, left and right cutting operations to reduce operator fatigue.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The rotation of the electric motor built in the main body 3 is converted into reciprocating motion, and the blade 8 is reciprocally moved to trim hedges, turfgrass, and the like. A switch 4 is built in the main body 3, and a loop type handle 2 for holding the main body 3 is fixed by a bolt 5. In order to protect the worker from the scattering of the cut branches, a protector 1 is attached to the front of the main body 3 with a fixing bolt 6, and the protector 1 has an adjusting long hole 9 capable of arbitrarily adjusting the trimming amount a, turfgrass, etc. A semi-circular projection 7 is formed that slides on the ground. By moving the protector 1 up and down using the elongated hole 9, the cutting amount a of the blade 8 can be adjusted. Further, since the projection 7 provided on the bottom surface of the protector 1 moves on the ground when cutting grass etc., it is not necessary for the worker to continue to support the trimmer main body 3 during the work, so that the fatigue of the worker can be reduced. it can.

[0007]

[Effect of the device]

 According to the present invention, since the protector is mounted so as to be movable up and down, and the protrusion that is in contact with the ground is provided on the bottom of the protector, a constant cutting height can be obtained and the cutting work can be performed without fatigue.
