Excavator hydraulic pliers:

        The gear rack fixed on the piston rod also reciprocates, thereby driving the spur gear meshing with the gear rack to rotate, and the driving bevel gear fixed with the spur gear will also drive the driven bevel gear meshing with it to rotate, thereby The sleeve is driven to rotate, and the lower part of the stick fixed at the end of the sleeve away from the fixed shaft also rotates circumferentially, so that the crushing pliers hinged on the lower part of the stick can rotate circumferentially according to the different angles of the workpiece to be crushed.

        The utility model is further arranged as follows: a pulling rope is fixedly connected between the upper part and the installation shaft. Through the above technical solution, when the driving bevel gear drives the driven bevel gear to rotate, the installation shaft can be prevented from being broken due to excessive force, and the strength of the installation shaft can be increased. The utility model is further configured as follows: a snap ring is fixed on the fixed shaft, a second snap ring is fixed on the inner circumferential surface of the sleeve, and one end of the second snap ring facing the upper part is connected to the upper part. An end of the snap ring facing the lower part abuts.
