Description

Fast rotating structure of wrench and its wrench (2)

The invention relates to a quick-rotation structure of a wrench and a spanner thereof, and more particularly to a structure for quickly rotating a ratchet head used on a spanner.

The industry often uses a wrench with a ratchet head to drive the screw (screw or nut) to tighten or loosen, and the wrench has the function of one-way reciprocating driving. Therefore, when driving the screw, you do not need to weigh as a fixed wrench. The cover is engaged with the rotating member, so that it can have better working efficiency when loosening or tightening the rotating member.

However, when the rotating part has been rotated on the object but there is no resistance, for example, if the sleeve of the wrench is engaged with the rotating part to perform the rotating operation, the wrench cannot produce a one-way rotating effect on the rotating part. The rotating part will only rotate back and forth with the pull of the wrench. If the operator wants to rotate the rotating part quickly, he often rotates the rotating part by hand, but the wrench and the rotating part must be rotated before rotating the rotating part by hand. The parts are detached, so the wrench cannot be directly loosened or tightened in the state where the sleeve is engaged with the rotating part, thereby causing the inconvenience and inefficiency of the wrench to drive the rotating part.

Therefore, how to solve the problem of the conventional wrench is the focus of the present invention to solve and improve.

In order to solve the above-mentioned problem, the present invention provides a wrench quick-rotation structure and a wrench thereof. The rocker arm and the base body are integrated or slidably assembled, and the rocker arm is protruded on one side of the base body, and the rocker arm can be mounted on the base body. The outside drives the seat body to rotate, so that the ratchet head linked with the seat body can be rotated quickly.

In order to achieve the above object, the present invention provides a wrench quick-rotation structure for rapidly rotating a ratchet head of a wrench, comprising: a base body which is provided in linkage with the ratchet head, and the base body has a predetermined height; a rocker arm It is integrated with the base body or is slidably assembled. The rocker arm protrudes on one side of the base body and can drive the base body to rotate outside the base body.

In order to achieve the above object, the present invention further provides a wrench with a quick-rotation structure of the wrench, comprising: a wrench having a driving end and a ratchet head at the driving end; a body provided in linkage with the ratchet head The base body has a predetermined height; a rocker arm is integrated with the base body or is slidably assembled, the rocker arm protrudes on one side of the base body and can drive the base body outside the base body Body rotation.
