Abstract
The utility model relates to a rotation preventing mechanism of a reciprocating lever for a reciprocating electric tool. The utility model comprises a reciprocating lever jacket which is arranged at the body of the reciprocating electric tool, and a reciprocating lever which is arranged in the reciprocating lever jacket in a sliding way. A guide slot which extends along the axial direction of the reciprocating lever jacket is arranged on the reciprocating lever jacket, the reciprocating lever is formed by the combination of the body of the reciprocating lever and the end element of the reciprocating lever, a rotation preventing lug which is convex along the radical direction of the reciprocating lever is arranged on the end element of the reciprocating lever, and the rotation preventing lug forms a sliding fit with the guide slot. The guide slot can make the rotation preventing lug only slide along the axial direction, so the reciprocating lever which does a rotary motion in the reciprocating lever jacket can be prevented.
Description
Technical field
The utility model relates to a kind of reciprocating lever rotation-preventing mechanism of reciprocating motor instrument.
Background technology
In the prior art, for the reciprocating lever that makes the reciprocating motor instrument does not axially rotate in the reciprocating lever cover, usually on reciprocating lever, fix one or two pin, the holddown groove that extends vertically is set on reciprocating lever, pin is inserted in prevents in the groove that reciprocating lever from rotating, but pin is too little with the contact area of groove, and this just causes the wearing and tearing of pin more serious, has influenced the service life of reciprocating motor instrument.
Summary of the invention
The utility model purpose provides a kind of reciprocating lever rotation-preventing mechanism of reciprocating motor instrument, can prevent that reciprocating lever from rotating the service life that can improve the reciprocating motor instrument again in the reciprocating lever cover.
For achieving the above object, the technical solution adopted in the utility model is: a kind of reciprocating lever rotation-preventing mechanism of reciprocating motor instrument, comprise the reciprocating lever cover that is arranged on the reciprocating motor tool body, be slidingly arranged in the reciprocating lever in the described reciprocating lever cover, described reciprocating lever cover is provided with along its axially extended gathering sill, described reciprocating lever is made of reciprocating rod subassembly and the combination of reciprocating lever tail piece, described reciprocating lever tail piece is provided with the anti-rotation projection along its radial protrusion, and described anti-rotation projection cooperates with described gathering sill slidably.
Because the technique scheme utilization, the utility model compared with prior art has following advantage: the contact area of anti-rotation projection and gathering sill is bigger, and it is just smaller to wear and tear, the service life of having improved the reciprocating motor instrument.
Description of drawings
Accompanying drawing 1 is the structure chart of reciprocating motor instrument;
Accompanying drawing 2 is a stereo appearance figure of the present utility model;
Accompanying drawing 3 is a stereo appearance figure of the present utility model;
Accompanying drawing 4 is a three-dimensional exploded view of the present utility model;
Wherein: 1, reciprocating lever; 2, reciprocating lever cover; 3, sliding bearing; 4, gathering sill; 5, anti-rotation projection; 6, reciprocating lever drive hole; 7, steady pin; 8, reciprocating motor tool body; 9, reciprocating lever tail piece; 10, reciprocating rod subassembly;
The specific embodiment
Referring to each accompanying drawing, a kind of reciprocating lever rotation-preventing mechanism of reciprocating motor instrument, comprise that the reciprocating lever that is arranged on the reciprocating motor tool body 8 overlaps 2, is slidingly arranged in the reciprocating levers 1 in the described reciprocating lever cover 2, described reciprocating lever cover 2 is provided with along its axially extended gathering sill 4, described reciprocating lever 1 is made of reciprocating rod subassembly 10 and 9 combinations of reciprocating lever tail piece, described reciprocating lever tail piece 9 is provided with the anti-rotation projection 5 along its radial protrusion, and described anti-rotation projection 5 cooperates with described gathering sill 4 slidably.Anti-rotation projection 5 can be along the endwisely slipping of reciprocating lever 1 in gathering sill 4, and gathering sill 4 has prevented the rotation of anti-rotation projection 5 simultaneously, makes reciprocating lever 1 only can overlap in 2 at reciprocating lever to slide vertically, and can not rotate.
Referring to accompanying drawing 4, described reciprocating rod subassembly 10 is fixedlyed connected by steady pin 7 with described reciprocating lever tail piece 9, is convenient to like this preventing the processing of reciprocating lever tail piece 9.
Claims (2)
