Abstract

Disclosed is a to-and-fro electromotion handsaw which is composed of a motor (1), a gear wheel (2), a reduction gear (3), a gear wheel (4) with the brim provided with holes, a pulling arm (5), a bearing (6), a saw bow body (7) and an insulation saw bow body shell (8), the utility model takes the motor as the driving force to pull the pulling arm to-and-fro through the reduction gear for reducing speed and an eccentric wheel, then the saw bow body is pulled to move to-and-fro, so the working purpose of the to-and-fro electromotion handsaw can be achieved.

Description

The reciprocating motor handsaw

Technical field

A kind of reciprocating motor handsaw is a kind of be used for cutting metal, wooden or back and forth linearly motion of a kind of instrument, especially saw blade that plastic material is used.

Background technology

At present people to want to saw some metal objects employed be the cutting machine of circular saw blade, saw blade is a grinding wheel, uses that noise is big, saw meets wide, dumb, inconvenient.Very little object can only cut with manual saw at present, the effort of both having taken a lot of work, and efficient is low again.

Summary of the invention

For people can be reduced labor intensity at work, can reach the purpose of work again, the utility model provides a kind of brand-new light saber saw, and it adopts the eccentric wheel principle that rotation is converted into reciprocating motion, thereby realizes conveniently application target.

The technical scheme that its technical problem that solves the utility model adopts is: by motor (1), gear (2), reduction gearing (3), the edge is provided with the gear (4) in hole, torque arm (5), bearing (6), saw bow body (7) and insulation saw bow body case (8) are formed, its middle gear (2) is connected on the motor (1), reduction gearing (3) and gear (2) are connected with a joggle, the edge is provided with the gear (4) and reduction gearing (3) engagement in hole, torque arm (5) one ends are movably connected in the edge and are provided with on the aperture at gear (4) edge in hole, the other end and saw bow body (7) flexibly connect, saw bow body (7) is connected with bearing (6), and bearing (6) is in the track of insulation saw body case (8).

The invention has the beneficial effects as follows: the hand held utilization is convenient, uses flexibly, and saw meets little, saves raw material.In use noise is little, does not disturb residents, and has improved workman's self work situation.

The specific embodiment

Be that motor (1) driven gear (2) rotates in scheming (9), gear (2) drives and drives gear (4) rotation that the edge is provided with the hole after reduction gearing (3) reduces the earthquake rotating speed.In figure (10), to drive torque arm (5) reciprocating because the gear (4) that the edge is provided with the hole has eccentric effect, thereby it is reciprocating to drive saw bow body (7), insulation saw body case (8) is provided with along the track of the reciprocating direction of saw bow body (7), and saw bow body (7) is made reciprocal easy motion by bearing (6) under the constraint that is provided with track on the insulation saw body case (8).

Claims

1. reciprocating motor handsaw, by motor (1), gear (2), reduction gearing (3), the edge is provided with the gear (4) in hole, torque arm (5), bearing (6), saw bow body (7) and insulation saw bow body case (8) are formed, it is characterized in that: gear (2) is connected on the motor (1), reduction gearing (3) and gear (2) are connected with a joggle, the edge is provided with the gear (4) and reduction gearing (3) engagement in hole, torque arm (5) one ends are movably connected in the edge and are provided with on the aperture at gear (4) edge in hole, the other end and saw bow body (7) flexibly connect, saw bow body (7) is connected with bearing (6), and bearing (6) is in the track of insulation saw body case (8).

2. reciprocating motor handsaw according to claim 1 is characterized in that, insulation saw body case (8) upper edge saw bow body (7) vibration-direction is provided with track.
