Description
Technical field
This utility model is related to bolt mounting and dismounting tool field, two recruitments that are more particularly, to a kind of laborsaving and accelerating rotation
Tool.
Background technology
In demounting bolt, it is initially required and just can be tampered with larger power；After tampering, dismounting is easier to need with comparatively fast
Dismounting speed to improve work efficiency；Install on the contrary during screw thread.Therefore, how to design a kind of laborsaving and accelerate rotation
Dual tool becomes technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide dual tool that is a kind of laborsaving and accelerating rotation, thus solving prior art
Present in foregoing problems.
To achieve these goals, the technical solution adopted in the utility model is as follows：A kind of laborsaving and accelerating rotation two
With instrument, including housing, in housing, it is provided with the first rotating shaft being rotatably connected with it and the second rotating shaft,
Also include little gear and gear wheel, the gear ratio of gear wheel and little gear is more than 5；
First rotating shaft and little gear spline connection, center spline connection, little gear and the canine tooth of the second rotating shaft and gear wheel
Wheel engagement, the part that hull outside is stretched out at the two ends of first rotating shaft is respectively equipped with the first squared ends and the second squared ends, the
The part that hull outside is stretched out at the two ends of two rotating shafts is respectively equipped with third party's shape end and square end, and first, second,
3rd, square end is equivalently-sized；
Also include box spanner and the reinforcing cylinder being in transmission connection with first, second, third, fourth squared ends, afterburning
The end of cylinder is provided with through hole, is provided with afterburning rod in through hole.
The beneficial effects of the utility model are：This utility model, can be by afterburning cylinder and first party when needing to accelerate rotation
Shape end or the second squared ends are connected, and third party's shape end or square end are connected with box spanner；
When needing laborsaving, afterburning cylinder can be connected with third party's shape end or square end, by the first squared ends or
Person second squared ends are connected with box spanner.This utility model is easy to use, operation facility.
