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
The present invention relates to spanner, relate in particular to a kind of can be according to the multifunctional wrench of the variable size wrench opening of nut.
Background technology
In machinery assembling and unloading process, often need tighten the bolt or the nut of (pine) different model, and common wrench can only be twisted a kind of nut of model, so then need a series of Wrench that vary in size, and carry very inconvenient.The Chinese patent document discloses many spanners, and a kind of adjustable Worm Wrench is especially arranged, and this spanner or to regulate the nuts that the wrench opening size adapts to different sizes through rotary worm is a kind of multi-functional spanners.Waste time and energy but this spanner uses relatively, and in stubborn nut process, the wrench opening size changes, locks bad easily, the nut corner angle are damaged, cause the part reuse relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of multifunctional wrench, solve that spanner of the prior art locking is unreliable, the deficiency of complex structure, working costs effort.
The scheme of technical solution problem of the present invention is: a kind of multifunctional wrench; Comprise handle and spanner; The spanner of the above connects through centrepin and described handle are movable in the termination of described handle; The locking device that also comprises said spanner, described locking device comprise the ratchet that is arranged on the described spanner, through pin and described handle movable connect also can with the sour jujube plate of described ratchet engagement and can be with the slide block of the fixed-site of described this sour jujube plate; Described slide block is arranged on the said handle.
Good effect of the present invention is owing to utilize movable jaw and locking device, is easy to adapt to the cap nut of different sizes, and can the length of handle freely be provided with, and uses easily.
Below will combine accompanying drawing and embodiment, the present invention will be further described.
