Description

Convenient spanner structure of dismantling for auto repair Technical Field The utility model relates to the technical field of maintenance wrenches, in particular to a convenient disassembly wrench structure for automobile maintenance. Background The spanner is the basic tool that is arranged in fastening or dismantlement bolt, nut in the auto repair, and common type includes open ended spanner, box spanner and box spanner, and open ended spanner both ends are the opening of fixed size, is fit for the operation of space open place, and the box spanner wraps up the nut with the annular, and antiskid effect is better, and box spanner collocation connects the pole to use, can go deep into narrow or sunken position operation. The material is mainly made of high-strength steel, and the durability and the wear resistance are both considered, so that the device is a common tool for disassembling tires, adjusting engine parts and other scenes in automobile maintenance. According to the search findings, the Chinese patent literature, bulletin number is CN222405440U, discloses an adjustable wrench with an extension structure, which comprises a handle, a fixed wrench head, a movable wrench head and a transmission worm, wherein one end of the handle is provided with the fixed wrench head, the inner side of the fixed wrench head is provided with the movable wrench head, the transmission worm is embedded and installed in the handle close to the movable wrench head, the movable wrench head is driven to move by rotating the transmission worm, the inner walls of the fixed wrench head and the movable wrench head are both provided with teeth, and the adjustable wrench with the extension structure is provided with a connecting sleeve which can be pulled outwards and limited by arranging the connecting sleeve on the outer side of the handle.
