[0050] It should be noted that: for the specific model of the double-acting cylinder 6, those skilled in the relevant art can select it by themselves, and the above about the double-acting cylinder 6 and the like all belong to the prior art, and this solution will not be elaborated.

[0051] Working principle of the utility model: When installing the upper box body 2, it is necessary for workers to lift the upper box body 2, align it manually, and then install the limit protrusion 16 provided at the bottom of the upper fixing frame 4 into the sealing groove 15 opened at the top of the lower fixing frame 3.

When it is necessary to maintain and repair the inside of the crusher, only the thrust of the push block 7 on the transmission rod 9 needs to be released. The transmission rod 9 moves downward under the pressure of the spring 14. When the transmission rod 9 moves downward, it drives the reset plate 10 to move, and the reset plate 10 drives the limit block 13 to rotate, thereby releasing the fixed state of the upper fixing frame 4 and the upper box body 2, so that the upper box body 2 can be quickly disassembled, facilitating manual maintenance of the inside of the crusher.

[0052] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
