[0035] The working principle of the present utility model:

[0036] When stabilizing the connection part of the output pipe 5, first smooth out the output pipe 5 after connecting it to the connection end 4 and align it inside the first clamping ring 72. Then, by pulling the moving seat 732 backward, while pulling, the moving seat 732 is driven to slide on the surface of the slide rail 731, and at the same time, the box body 81 is driven to move on the slide rail 731. After moving the moving seat 732 to the position where the second clamping ring 733 and the first clamping ring 72 cooperate to clamp the output pipe 5, the position of the pin head 824 will correspond to the position of the positioning groove 832 on the fixing plate 831. At this time, the push spring 823 will push the push plate 822 to move leftward on the surface of the moving rod 821. The movement of the push plate 822 drives the pin head 824 to move leftward and insert into the corresponding positioning groove 832 to position the moving seat 732, thus completing the stabilization of the connection part of the output pipe 5. When disassembling and assembling the output pipe 5 to release the fixation later, by pulling the pull button 825 to the right, while pulling, the push plate 822 is driven to move leftward on the surface of the moving rod 821, and at the same time, the push spring 823 is compressed. The movement of the push plate 822 drives the pin head 824 to move into the box body 81, so that the pin head 824 moves out of the positioning groove 832, releasing the positioning of the clamping component 73. Then, pull the moving seat 732 forward to drive the second clamping ring 733 away from the output pipe 5, thus releasing the stabilization of the output pipe 5.
