[0035] The connecting block 11 is fixedly connected to the slider 10. The outer sides of the first column 4 and the second column 5 are provided with moving holes 111 for the connecting block 11 to move up and down. Starting the electric slide 9 drives the slider 10 to move synchronously, thereby allowing the connecting block 11 to move and adjust, thereby achieving the purpose of adjusting the height of the arc clamp 7.

[0036] In this embodiment, the filling mobile assembly includes a conveying device 13 installed inside the base 2 and a gas transmission mechanism 14 fixedly installed at the output end of the liquid storage tank 1.
