The first pad 3 is arranged between the base 1 and the breaker pick assembly to support the bottom of the breaker pick assembly; the second pad 4 is arranged between the cover plate assembly 2 and the breaker pick assembly to support the top of the breaker pick assembly. The bottom of the base 1 is provided with a sliding fit structure for sliding fit with the propulsion beam. The breaker pick impact tool can be directly installed on the propulsion beam of the anchor trolley, thereby replacing the high-cost rock drill to complete the impact installation of the anchor, thereby reducing costs.

The first end of the second pad 4 contacts and cooperates with the cover plate assembly 2, and the second end of the second pad 4 contacts and cooperates with the curved surface structure on the top of the crushing pick body 5 to protect the top of the crushing pick body 5 from being pressed.

[0053] In the specific application process, the sliding matching structure is a slider clamping plate 9 symmetrically arranged on both sides of the bottom of the base 1 by bolt connection or welding, and the slider clamping plate 9 is provided with a dovetail-shaped sliding groove 901 on the inner side to match the guide rail 11 on the anchor trolley push beam, that is, Figure 7 It is worth noting that the sliding fit structure can also be set as a sliding groove structure.
