[0002] Jaw crushers are mainly used as coarse crushers and medium crushers in mining, building materials, infrastructure and other departments. The working part of the jaw crusher is two jaw plates, a fixed jaw plate and a movable jaw plate. The movable jaw plate performs periodic reciprocating motion against the fixed jaw plate, sometimes separating and sometimes approaching. When separating, the material enters the crushing chamber and the finished product is discharged from the bottom. When approaching, the material loaded between the two jaw plates is squeezed, bent and split to be crushed.

[0003] The existing patent (Announcement No.: CN214159729U) discloses a movable tooth plate for a jaw crusher, including a bottom plate and a crushing tooth group, wherein the crushing tooth group includes a plurality of crushing teeth whose axes are parallel to each other, and a slider is provided at the bottom of each of the crushing teeth. When the crushing teeth are damaged, it is only necessary to unscrew the positioning bolts and then remove the positioning plate, and the crushing teeth can be taken out along the open end of the dovetail groove, thereby achieving the replacement of the crushing teeth, changing the problem that the existing movable tooth plate needs to be replaced as a whole even if it is partially damaged. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: the above-mentioned device disassembles and replaces the crushing teeth by positioning bolts, but screwdrivers, wrenches and other tools are required to disassemble the positioning bolts, which results in the need to consume movement time when disassembling and replacing the crushing teeth, reducing the speed of the jaw crusher in crushing stones.
