Embodiment Construction

[0012] Such as figure 1 It is a schematic diagram of the structure of the present invention, a double-headed open wrench, including a wrench 1 and a handle 2, which are fixedly connected. The handle 2 is divided into a left handle and a right handle. The left handle and the right handle pass through a socket 3 with a locking bolt. In a fixed connection, a tooth pattern is provided on the surface of the left handle, a matching tooth pattern is arranged on the contact surface of the right handle and the left handle, and the sleeve 3 is a stainless steel pipe sleeve.

[0013] The double-headed open spanner realizes the adjustable handle through the left handle and the right handle connected by the tooth pattern meshing, and adapts to different use requirements, and is fixed and locked by a socket, which effectively improves the use efficiency.

[0014] The above description is only illustrative but not restrictive to the present invention. Those of ordinary skill in the art understand...

Abstract

The invention relates to the technical field of hardware tools, in particular to a stud head spanner. The stud head spanner comprises a spanner head and a handle which are fixedly connected, wherein the handle is divided into a left handle and a right handle which are fixedly connected through a sleeving part, and the sleeving part is provided with a locking bolt; tooth textures are formed in thesurface of the left handle; fitting tooth textures are formed in a surface where the right handle is in contact with the left handle; and the sleeving part is a stainless steel pipe sleeve. Accordingto the stud head spanner, the handle can be adjusted through the left handle and the right handle which are engaged and connected through the tooth textures, and thus different use demands can be met;and in addition, the sleeving part is used for fixing and locking, so that the use efficiency is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of hardware tools, in particular to a double-headed wrench. Background technique [0002] Wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threads to hold the openings or sleeves of bolts or nuts. The wrench is usually made of carbon or alloy materials. Made of steel, wrenches are usually made with openings or sockets for holding bolts or nuts at one or both ends of the handle. When in use, an external force is applied to the handle along the thread rotation direction to turn the bolt or nut. [0003] The existing double-headed open spanner has a fixed structure and a single function, and the length of the handle cannot be adjusted according to the use demand, which cannot meet the increasing use demand of people. Summary of the invention [0004] In order to overcome the shortcomings of the existing handle struc...
