Referring to figure 5. and Fig. 6 optionally opens up mounting groove 1211 on the first impact block 121, is used for installation locking device
170.Locking device 170 includes locking post 171, connecting cylinder 174, elastic component 172, extrusion 173, upper end cover 177, lower cover
178, sleeve 176, supporting piece 175 and hydraulic package；Elastic component 172 and connecting cylinder 174 are respectively sleeved in locking post 171, and
Elastic component 172 is abutted with connecting cylinder 174.Optionally, stepped hole is opened up in extrusion 173, elastic component is installed in the upper end of stepped hole
172, connecting cylinder 174 is installed in lower end, and upper end cover 177 is fixedly connected with extrusion 173, such as fixed by bolt.Elastic component 172
One end be fixed on upper end cover 177, the other end supports on connecting cylinder 174.Supporting piece 175, supporting piece are installed in sleeve 176
175 abut with connecting cylinder 174, and sleeve 176 is fixedly connected with extrusion 173, and lower cover 178 is fixedly connected with sleeve 176, lower end
Lid 178 is fixedly connected with the first impact block 121.Locking post 171 sequentially passes through upper end cover 177 from top to bottom, elastic component 172, connects
Connect cylinder 174, supporting piece 175, the first impact block 121, the second impact block 123, locking post 171 and the second impact block 123 are fixed to be connected
It connects.Optionally, the second impact block 123 is equipped with locking hole 1236, for being inserted into for locking post 171.Elastic component 172 pushes connection
Cylinder 174 is moved along the direction close to the second impact block 123, and extrusion 173 and connecting cylinder 174 squeeze locking post 171, prevents from locking
Column 171 falls；Hydraulic package is connect with connecting cylinder 174, and hydraulic package pushes connecting cylinder 174 along separate second impact block 123
Direction is mobile, and extrusion 173 and connecting cylinder 174 discharge locking post 171, and locking post 171 falls together with the second impact block 123.
Since connecting cylinder 174 is mounted in extrusion 173, i.e., extrusion 173 is set on connecting cylinder 174, connecting cylinder 174
It is located between extrusion 173 and locking post 171.The outer surface of connecting cylinder 174 has first conical surface 1741, extrusion 173
