[0024] The outer walls of the multiple mounting frames 401 on the side away from each other are rotatably connected to a bevel gear 405, and the multiple bevel gears 405 are coaxially fixed to one end of the multiple screw rods 402 respectively. The outer wall of one end of the mounting frame 1 is rotatably connected to a bevel gear ring 406, and the multiple bevel gears 405 are meshed with the bevel gear ring 406.

[0025] By starting the motor 407 inside the mounting frame 1, a bevel gear 405 is driven to rotate. The bevel gear 405 drives the bevel gear ring 406 to rotate inside the mounting frame 1 through meshing. The bevel gear ring 406 can drive the other bevel gears 405 to rotate synchronously through meshing, so that the multiple screw rods 402 will also rotate at the same time, and the mounting blocks 403 restricted by the mounting frame 401 will be driven by the screw rod 402 to approach each other. At this time, the multiple fastening frames 404 will also move synchronously with the mounting blocks 403 until the multiple mounting blocks 403 cooperate with each other to fix the gun head.

[0026] like Figure 2 and Figure 4 As shown, a mounting assembly 5 is installed outside the mounting frame 1 , and the mounting assembly 5 includes two extension frames 504 fixedly connected to the two sides of the circumferential outer wall of the mounting frame 1 , and a clamping plate 505 is slidably connected inside the two extension frames 504 .
