As shown in fig. 1-7, the present application provides a jaw crusher comprising a body 1. The body 1 serves as the main structure of the crusher for supporting the various components and for withstanding the forces generated during operation.

The inner side of one end of the machine body 1 is provided with a static jaw assembly 2, and the static jaw assembly 2 plays a role in supporting and fixing the jaw plate 4, so that the jaw plate 4 can stably carry out crushing operation. The bottom of the static jaw assembly 2 is connected with a collet 3, and the collet 3 is used for supporting the jaw plate 4 and providing stable supporting force when the jaw plate 4 is replaced.

The side of quiet jaw subassembly 2 is connected with jaw 4, and jaw 4 is the key component of direct participation crushing operation, can bear the direct impact of broken material, and connects through the mode of block between bottom one side and the collet 3 of jaw 4, and this kind of connected mode has made things convenient for the change of jaw 4 to stable connection has been provided.

The clamping groove 32 has been seted up to one side of collet 3, and clamping groove 32 has good suitability, and bottom one side fixedly connected with clamping sand grip 41 of jaw 4, and clamping sand grip 41 can accurately block into clamping groove 32 in, has realized the close connection of jaw 4 and collet 3, has strengthened its stability.

Referring to fig. 5, in order to ensure the fixed connection of the jaw 4 and the shoe 3, a threaded hole 321 is formed through one side of the inside of the clamping groove 32, and the threaded hole 321 can be used for mounting a screw, so as to realize a more firm connection of the jaw 4 and the shoe 3. Also, the threaded holes 321 are equally spaced, which is advantageous in improving the stability and service life of the jaw 4.

Referring to fig. 3 and 6, the static jaw assembly 2 further includes a connection plate 21, a first connection hole 211 is formed through a side surface of the connection plate 21, a third connection hole 42 is formed through a top side surface of the jaw plate 4, and the third connection hole 42 and the first connection hole 211 correspond to each other, so that the jaw plate 4 can be conveniently connected with the static jaw assembly 2, and replacement of the jaw plate 4 is more convenient and quick.
