[0037] When different puncture needles need to be adapted during operation, the limiting rod 53 is removed, and then the elastic plate 55 is pulled. The elastic plate 55 drives the fixed plate 54, the mounting plate 52, and the mounting rod 51 to move, so that the mounting rod 51 moves away from the corresponding slider 42. Then, the elastic plate 55 that meets the requirements is inserted into the mounting port 3, and then the mounting rod 51 in the elastic plate 55 is inserted into the corresponding slider 42.
