Description

This creation is related to a penetrating ratchet wrench, in particular to a type that can hold the sleeve in the ratchet to prevent the sleeve from falling during operation.

The conventional penetrating ratchet wrench (or a ratchet wrench) has a multi-angle slot (6 or 12 angles) in the center of the ratchet for inserting the hexagonal column end of the sleeve to facilitate the user. The operating wrench drives the sleeve to screw or disassemble workpieces such as bolts or nuts. However, the conventional multi-angle slot wall surface is a flat surface, and there is no fastening design between the multi-angle slot and the sleeve, so that the sleeve mounted on the wrench is easy to fall off and be lost during the wrench picking process.

Although some manufacturers have elastic card beads in the sleeve part to make the sleeve and the wrench elastically fastened, such as the Republic of China No. M426472 patent. However, this conventional technique requires a specific wrench and a sleeve to be matched. The wrench and the sleeve are respectively provided with elastic beads and corresponding card slots. If used with a general wrench or a sleeve, it is too tight to be inserted. , or too loose and easy to drop. Therefore, the problem that the sleeves and the wrenches of the various manufacturers cannot be mixed is caused, and when the user works, it is easy to have the sleeves taken incorrectly, and it is difficult to use them together, and it is often troublesome to replace the correct wrenches and sleeves.

Another conventional technique is bent in an iron wire or a spring wire and placed in a multi-angle slot to create an elastic locking effect on the sleeve to achieve the purpose of clamping the fixing sleeve, such as the Republic of China No. 488342, 539599 , M378077, M378078, M432503, I311092, all belong to this technical model. However, the shape of the spring wire is complicated to bend, and there are many problems in the molding process.

In general, the shortcomings of the prior art generally include that the conventional penetrating ratchet wrench and the sleeve are not easily fixed directly, and the special design such as the elastic card bead has the problem that the sleeves and the wrenches cannot be mixed. When the elastic wire is bent by the wire or the spring wire, the bending shape is complicated and the processing is difficult. In view of the above shortcomings, the present invention proposes a solution of a penetrating ratchet wrench with a sleeve clamping device, which can achieve the purpose of clamping and fixing the sleeve in the ratchet to prevent the sleeve from falling during operation. outer. The sleeve does not need to be specially designed so that the penetrating ratchet wrench of the present invention can be applied to each sleeve.
