A socket rubber sealing sleeve 207 is provided on the inner side of the left end. A socket flat washer 208 is provided on the side of the socket rubber sealing sleeve 207. A socket locking cap 210 is provided on the side of the socket flat washer 208 and is connected to the socket transition sleeve by a second fastening screw 205. The socket locking cap 210 is connected to the socket clamp plate 209 by a second spring washer 211 and a socket screw 212. A pin assembly 204 is provided on the inner side of the right end of the socket transition cover 206 through a retaining ring 203.
