[0002] During the rock cracking process, after the rock is cracked, the cracked edge of the rock is easy to tilt and squeeze the splitter, damaging the outside of the splitter and causing damage to the splitter. Among them, the "A rock hydraulic splitter" disclosed with the application number "CN202322317153.6" is also an increasingly mature technology. By arranging a fixing plate and a gripping plate on the outer side of the lower end of the hydraulic cylinder body to fix and limit the hydraulic cylinder body, when in use, the operator can place the device into the hole opened in the rock in advance by the handle. The fixing plate and the gripping plate will fix and support the hydraulic cylinder body on the rock. The operator can drive the fixing nails into the rock along the fixing groove The method increases stability, wherein the fixed plate and the gripping plate are connected by a rotating shaft, has greater damping, and can also allow the fixed plate and the gripping plate to be used at multiple angles, and has high practicality. The operator can also hang the hook on a nearby supporting point through a connecting rope on one side, which can effectively prevent the splitter from falling with the dumped rock after splitting the rock. However, the device still has the following defects: in actual use, the crusher generally breaks the rock from the inside during use, and the crusher's blade is not easy to insert into the rock. At the same time, after the rock is broken, it is not easy to expand the rock fracture gap, which affects the rock fracture effect. Utility Model Content
