There is a worm gear 306, and the driving component 4 includes a slide plate 401 which is slidably connected to the left and right sides of the bottom plate 1, and a guide plate 402 is fixedly provided on the inner side of the slide plate 401, a latch 403 is fixedly provided on the inner upper end of the slide plate 401, a sliding pin 404 is provided inside the guide plate 402, a mounting plate 405 is rotatably sleeved on the outer front end of the sliding pin 404, a handle 406 is fixedly provided on the middle side of the front end of the mounting plate 405, a worm 407 connected on the right side of the mounting plate 405 is meshed with the gear teeth of the worm gear 306, and a spring 408 is fixedly provided between the outer lower end of the slide plate 401 and the bottom plate 1.

[0027] The top of the support rod 301 rotates and penetrates the top of the bracket 2, the connecting rod 304 slides and penetrates the top of the bracket 2, the left and right sides of the outside of the mounting plate 405 are slidably connected with the inner wall of the bracket 2, and the plurality of sockets 305 are designed to be annular, and the center of the circular ring formed by the plurality of sockets 305 is concentric with the center of the support rod 301. The staff first pulls the handle 406 upward with his left hand, so that the handle 406 drives the mounting plate 405 together with the sliding pin 404 to push the guide plate 402 to control the two slide plates 401 to move in opposite directions, and the spring 408 is deformed. At this time, the slide plate 401 drives the pin 403 to disengage from the socket 305, and the staff then rotates the worm 407 with his right hand, and the worm 407 controls the worm wheel 306 to drive the support rod 301 to rotate, and through the threaded transmission of the support rod 301 and the screw 302, the screw 302 drives the support plate 303 together with the connecting pin 404 to move in opposite directions.
