[0022] That is, the driving assembly is set to extrude and drive the movable plug column 603, and the movable plug column 603 drives the positioning plug rod 605 to be clamped with the positioning clamping groove 31 on the corresponding position of the breaking rod head 3, so as to quickly realize the position positioning of the supporting disc 4, and then the supporting work is carried out under the driving action of the hydraulic device 1.

[0023] In combination with the accompanying drawings Figure 7 - the accompanying drawings Figure 8 As shown in the figure, wherein the auxiliary assembly includes the accommodating groove cavity 601 symmetrically arranged in the supporting disc 4; the cavity opening of the accommodating groove cavity 601 is circular, and one end of the accommodating groove cavity 601 extends to the outer side surface of the supporting disc 4; a communication slot 602 is arranged at the other end of the accommodating groove cavity 601, and one end of the communication slot 602 extends to the inner side wall of the supporting disc 4.

[0024] The movable plug column 603 is inserted and placed in the accommodating groove cavity 601; a spherical surface body 604 is arranged at one end of the movable plug column 603, and a positioning plug rod 605 is fixedly arranged at the other end of the movable plug column 603, and the positioning plug rod 605 is inserted and arranged in the communication slot 602; an auxiliary spring 606 is fixedly arranged at the connecting end of the movable plug column 603 and the positioning plug rod 605, and the other end of the auxiliary spring 606 is fixedly arranged on a connecting sleeve ring 607, and the connecting sleeve ring 607 is movably sleeved on the positioning plug rod 605; the end of the positioning plug rod 605 is matched and clamped with the positioning clamping groove 31 on the side wall of the breaking rod head 3.

[0025] That is, for the positioning work of the supporting disc 4, after the supporting disc 4 is moved to the appropriate position, the positioning plug rod 605 arranged in the communication slot 602 is clamped with the positioning clamping groove 31 on the corresponding position of the side wall of the breaking rod head 3 to realize the positioning, and the positioning clamping groove 31 is equally arranged with multiple groups on the side wall of the breaking rod head 3, so as to realize the positioning of multiple positions, and the positioning operation of the supporting disc 4 has good flexibility.

[0026] In order to further improve the positioning of the plug rod 605 and the clamping stability of the positioning card slot 31, the auxiliary elastic sheet 608 is arranged at the end of the positioning plug rod 605; that is, when the end of the positioning plug rod 605 enters the positioning card slot 31, the auxiliary elastic sheet 608 arranged at the end of the positioning plug rod 605 will first enter the positioning card slot 31, and the auxiliary elastic sheet 608 is extruded, and the extruded auxiliary elastic sheet 608 will be tightly attached to the side wall of the positioning card slot 31 in this process, so as to avoid the problem of loosening after the positioning plug rod 605 is clamped with the positioning card slot 31.

[0027] In combination with the accompanying drawings Figure 5 -attached Figure 6 As shown in the drawings, the driving assembly is arranged to drive the movable plug column 603.

[0028] The driving assembly comprises a half ring body 701. Two half ring bodies 701 are arranged to form a wrapped ring body. A butt plate 702 is arranged at the outer side of the two ends of the half ring body 701. The butt plate 702 arranged at the end of the half ring body 701 is contacted and fixed by a bolt. A wrapped side edge 703 is symmetrically arranged at the two sides of the half ring body 701. The wrapped side edge 703 provides a limit for the rotation of the wrapped ring body. An extrusion inclined groove 704 is arranged on the inner side wall of the half ring body 701. The spherical surface body 604 at one end of the movable plug column 603 extends into the extrusion inclined groove 704, and a group of extrusion inclined grooves 704 are arranged in the half ring body 701.

[0029] That is, after the movable plug column 603 is placed in the accommodating groove 601 in the supporting disc 4, the positioning plug rod 605 arranged at one end of the movable plug column 603 will enter the communication slot 602, and the connecting sleeve ring 607 arranged on the positioning plug rod 605 will reach the innermost end of the accommodating groove 601. At the same time, the spherical surface body 604 arranged at one end of the movable plug column 603 will be outside the cavity opening of the accommodating groove 601.
