Then, the nut 40 is supported so as not to rotate, and when the electric drill 20 is operated at a position where the male screw portion 30a of the spindle 30 and the female screw portion 40a of the nut 40 are screwed together, the nut 40 is attached to the spindle 30 by the action of the screw. It will move in the axial direction.
- the moving direction of the nut 40 is determined by the rotating direction of the electric drill 20. Further, the moving distance depends on the length with which the male screw portion 30a and the female screw portion 40a are screwed together. That is, in the case of the wire cutting tool 10, the lengths of the male screw portion 30a and the female screw portion 40a may be determined in consideration of the moving distance that the working parts 51 and 52 can cut with the electric wire 100 interposed therebetween.

- the movable body 41 In order for the movable body 41 to move in the axial direction of the spindle 30, the movable body 41 should not rotate along with the rotation of the spindle 30. Moreover, since the electric wire 100 cannot be cut unless the first and second working parts 51 and 52 are linearly opened and closed, the spindle holder 35 connected to the second working part 52 is also rotated. should not. In order to prevent the spindle holder 35 and the movable body 41 from rotating in accordance with the rotation of the spindle 30, a fixture 80 is provided. One end of the fixture 80 is connected to the spindle holder 35, and the other end is locked to the handle portion of the electric drill 20. Thereby, the rotation of the spindle holder 35 is suppressed.
- the fixture 80 has a structure that simultaneously suppresses the rotational motion of the movable body 41.
- the movable body 41 has a structure that sandwiches the spindle holder 35. Therefore, if the rotation of the spindle holder 35 is suppressed, the movable body 41 also suppresses the rotational movement. It will be in the state.
- a portion that is locked to the electric drill 20 is a fixing rod 81, and a member that connects the fixing rod 81 and the spindle holder 35 is an arm 82.
- the fixing rod 81 has a J shape like an umbrella handle, and can be hooked on the handle portion of the electric drill 20.

- the connecting portion with 82 is configured to be rotatable about the left-right direction of the electric drill 20 as an axis.
- the work parts 51 and 52 are blade parts.
- the first working unit 51 attached to the movable body 41 is a movable blade
- the second working unit 52 attached to the spindle holder 35 is a fixed blade.
- a long hole 43 serving as a guide is provided in the fixed blade 52, and a shaft rod 44 that can move along the long hole 43 is provided so as to penetrate the movable body 41 and the movable blade 51.
- the fixed blade 52 and the movable blade 51 have to slide without gaps, so that the fixed blade 52 and the movable blade 51 are pressed by the shaft bar 44 so as to be in close contact with each other. Yes.
- the shaft 44 has a configuration in which the fixed blade 52, the movable blade 51, and the movable body 41 are overlapped to apply a surface pressure from the outside, but the thickness may be adjusted with an annular spacer 45 interposed therebetween. .
- the role of friction reduction can also be fulfilled by sandwiching the spacer 45.
- FIGS. 5A and 5B are diagrams illustrating the internal structure of the wire cutting tool, where FIG. 5A shows a state where the working unit is open, and FIG. 5B shows a state where the working unit is closed.
- the moving direction of the movable body 41 is reversed and reciprocated by reversing the turning direction by the switch of the electric drill 20. be able to.
- the movable body 41 moves to a position where the male screw portion 30a and the female screw portion 40a are disengaged, the spindle 30 rotates idly and the linear motion of the movable body 41 stops.
- the rotation of the electric drill 20 is reversed in order to move the movable body 41 in the reverse direction, it cannot be immediately screwed in a state in which the male screw portion 30a and the female screw portion 40a are disengaged. There is a problem.
- a first elastic member 61 is provided to urge the female screw portion 40a toward the male screw portion 30a.
- a second elastic member 62 is provided to urge the female screw portion 40a toward the male screw portion 30a.
- the female screw portion 40a is pressed toward the male screw portion 30a by the biasing force of one of the springs when the screw is disengaged. Therefore, when the rotation of the electric drill 20 is reversed, the male screw portion 30a and the female screw portion 40a are screwed again, and the movable body 41 can immediately move straight in the reverse direction. Furthermore, it is preferable to chamfer the front and rear of each threaded portion so that the male screw portion 30a and the female screw portion 40a can be easily screwed together.
- first and second guide rollers 71 and 72 may be provided on the female threaded portion 40a side of the first and second springs 61 and 62, respectively.
- first spring 61 when the working unit in FIG. 5A is in an open state, the first spring 61 is compressed by the spindle holder 35 and the first guide roller 71, The female screw portion 40a is pressed toward the male screw portion 30a through the guide roller.
- the working portion in FIG. 5B is closed, the second spring 62 is compressed by the retaining ring 73 attached to the spindle 30 and the second guide roller 72, and The female screw portion 40a is pressed toward the male screw portion 30a via the second guide roller 72.
- the first and second guide rollers 71 and 72 have a ring shape and are in contact with the spindle 30 on the inner side of the ring and are in contact with the smooth inner surface of the nut 40 on the outer side of the ring. And the shaft of the nut 40 can be kept the same. As a result, the shafts of the male threaded portion 30a of the spindle 30 and the female threaded portion 40a of the nut 40 are also the same. Further, since the guide rollers 71 and 72 also function as a sliding bearing that mediates between the spindle 30 and the nut 40, it is possible to prevent energy loss due to friction and suppress heat generation.
- the wire cutting tool using the linear reciprocating device having the above-described configuration realizes conversion of the rotation of the electric drill into linear reciprocating motion with a simple structure, and smooth reciprocating movement of the working unit. It has been realized.
