Description

[Detailed description of the invention] This invention relates to a tapping type pine serge machine that performs a tapping operation by intermittent driving of a solenoid housed in the head, and its purpose is to securely fix the head cover with a simple structure.

FIG. 1 is a partially cutaway side view of an embodiment of this invention.

That is, in this tapping type pine serge machine, a head 1 and a grip 2 are connected by a connecting spring body 3, and intermittent power is supplied from a drive circuit body 4 built in the grip 2 through a lead wire 6 to a solenoid 5 built in the head 1. By doing so, the solenoid 5 is intermittently suctioned, and the attachment 7 is rapidly moved forward and backward.

The connecting spring body 3 and the lead wire 6 are covered with a cover 8 made of soft vinyl chloride resin, which is an elastic insulating material. without damaging
The edge portion of the connecting spring body 3 can be prevented from damaging the human body, and the insulation of the lead wire 6 can be improved.

In FIG. 1, 9 is a switch, and 10 is a power cord.

2 and 3 show the structure of the head 1, respectively.

That is, a pair of head covers 11 are formed by dividing a solenoid 5 which is intermittently driven by a plane perpendicular to its operating direction.
．． 12, and this pair of head covers 1
1.12 are connected to one screw fastening joint 13 and three engaging joints 14, 15.16, and the first retaining joint 14 is arranged at a symmetrical position to the screw fastening joint 13. At the same time, a line B perpendicular to the line A connecting the first retaining joint 14 and the screw fastening joint 13 and a line B connecting the first retaining joint 14 and the screw fastening joint 13
The second and third retaining joints 15 and 16 are arranged separately between the lines c and c' which are slanted 30' in the direction of the arrows.

In reality, the second and third engaging coupling portions 15,16 were arranged on lines deviated by 15°.

In this way, the head cover 11.12 is fixed with one screw fastening joint 13 and three engaging joints 14 to 16, and each of the joints 13 to 16 is arranged as described above. Therefore, the head covers 11 and 12 can be securely fixed and easy to assemble.

This will be explained further.

The first engagement coupling part 14 is arranged in a position symmetrical to the screw fastening coupling part 13 with respect to the center of the head cover 11.12, and
If the second and third engaging joints 15 and 16 are placed on the line B perpendicular to the line A connecting the engaging joint 14 and the screw fastening joint 13 (at positions divided into four equal parts of 90°), the fixation will be achieved. Although it can be made strong, the adjacent engagement joints 14.15 (14, 16)
Because the pitch between them is narrow, a pair of head covers 11.12
is difficult to disassemble.

When removing the engagement joints 14 to 16, remove the head cover 11.
．． 12 to deform and remove the head covers 11, 12, but if the pitch is narrow, the head covers 11, 12 are difficult to deform and are difficult to remove.

In addition, if the second and third retaining joints 15 and 16 are placed on line C deflected by 30 degrees or in a position further deviated toward the screw fastening joint 13, the pitch will become wider and it will be easier to disassemble. , the fixation becomes weaker.

In this invention, second and third engagements are formed between a line B perpendicular to the line A connecting the first engagement coupling part 14 and the screw fastening coupling part 13, and a line C slanted by 30 degrees from this line. Joint part 15.1
6, so a pair of head covers 11.12
The fixation of the head covers 11 and 12 is strong and does not easily come off due to falling impact, and there is no collision noise between the head covers 11 and 12, and the cover is easy to disassemble.

In addition, the head cover 11.12 needs to be made as small as possible so that it can be easily applied to the affected area, so the screw fastening joint 13 is made to protrude beyond the outer circumference of the head cover 11.12. Since they are arranged at the same circumferential position of the grip 2, the screw fastening joint 13 does not hit the neck or the like when hitting the shoulder and does not get in the way.

As described above, the tapping type pine serge machine of this invention can securely connect and fix the head cover with a simple structure, and there is no impact noise between the head covers caused by the operation of the solenoid, and the assembly work is easy.
