Description

Wrench with stop device

The invention mainly discloses a wrench, especially a wrench with a stop device.

Please refer to the Chinese Patent No. M476030 "Improved Structure of Penetrating Wrench" patent case, which discloses an improved structure of a penetrating wrench, which has a wrench body, and the front end of the wrench body has a head, A ratchet is provided in the head, and a polygonal socket is provided on the ratchet, and the socket is used to socket a sleeve. In addition, a first neck is provided on the upper edge of the ratchet. Moreover, a ring groove is provided on the peripheral wall of the first neck, and the ratchet has a plurality of perforations in the ring groove. At the same time, a C-shaped buckle is buckled in the ring groove, and the perforations are available for the The C-shaped buckle protrudes to form a limiting portion. The limiting portion can be elastically stopped at the sleeve, thereby restricting the sleeve by the socket hole of the ratchet during the operation of the user. Displacement on the barrel.

However, when producing a wrench with the above structure, a ring groove must be machined on the peripheral wall outside the first neck of the upper edge of the ratchet. With this effect, nowadays, it is necessary to reprocess the ring groove in the ratchet, which makes the structure of the ratchet more and more complicated, and it is more and more difficult to process, which makes the production of wrenches more difficult and increases the cost of manufacturing.

In addition, the way the wrench restricts the position of the sleeve relies on the elasticity of the C-shaped buckle itself. When the user has used the sleeve or wants to replace the sleeve of another size, he must hold the sleeve and then directly remove the sleeve. The wrench is pulled out, but the sleeve is likely to be contaminated with oil during use. If the elastic coefficient of the C-shaped buckle is too large, the user may encounter the problem that it is difficult to remove the sleeve due to insufficient friction. On the contrary, if If the elasticity of the C-shaped buckle is too small, it will cause the sleeve to easily fall off during use.
