Abstract

The invention discloses a multifunctional wrench, comprising a handle, a wrench head which is flexibly connected with the handle by a center pin on the end of the handle, and a locking device of the wrench head; wherein, the locking device comprises a ratchet arranged on the wrench head, a ratchet plate which is flexibly connected with the handle by a pin and engaged with the ratchet, and a sliding block which can fix the position of the ratchet plate and is arranged on the handle. In the technical proposal, the flexible wrench is utilized, thus being easily suitable for screw caps with different sizes and being capable of freely setting the length of the handle, with very convenient use.

Description

technical field [0001] The invention relates to a wrench, in particular to a multifunctional wrench capable of changing the opening of the wrench according to the size of the nut. Background technique [0002] In the process of mechanical assembly and disassembly, it is often necessary to tighten (loosen) different types of bolts or nuts, while ordinary wrenches can only screw a specific type of nut, so a series of wrench tools of different sizes are required, and it is very uncomfortable to carry. convenient. Chinese patent literature discloses many wrenches, especially an adjustable worm wrench, which is a multifunctional wrench by adjusting the size of the opening of the wrench to adapt to different sizes of nuts by rotating the worm. However, this kind of wrench is time-consuming and laborious to use, and in the process of screwing the nut, the size of the opening of the wrench is easy to change, and the locking is not good, which will damage the corners of the nut, res...
