The locking fastener 542 and the second pushing member 52 move synchronously, when the second pushing member 52 is pushed, the locking fastener 542 moves towards the locking block 541, and as the second pushing member 52 moves continuously, the locking fastener 542 can be buckled in the locking clamping position 5411 on the locking block 541, so as to lock the position of the second pushing member 52, further stabilize the suction pressure in the suction tube 23, and keep the suction pressure in the suction tube 23 constant. The locking block 541 is provided with a plurality of locking clamping positions 5411, when the locking fastener 542 is fastened at different locking clamping positions 5411, the clamping degree of the suction tube 23 is different, and the adjustment of different suction pressures of the suction tube 23 is realized by arranging the locking fastener 542 in different locking clamping positions 5411. It can be understood that the pressing of the second key 51 requires a larger force, and long-time pressing easily causes hand fatigue, in this embodiment, the position of the second pushing member 52 is locked by the cooperation of the locking fastener 542 and the locking block 541, so that hand fatigue caused by long-time pressing of the second key 51 is avoided, and accurate attractive force can be maintained, which is convenient for a doctor to apply constant attractive force to a target area, and prevent injuries of organs by mistake.

Specifically, the second pushing member 52 includes a second push rod 521 and a second push plate 522 disposed on a side of the second limiting plate 531 facing away from the second key 51, where the second push plate 522 is slidably disposed on a side of the second fixing plate 532, and one end of the second push plate 522 facing away from the second limiting plate 531 is capable of extruding the suction tube 23, and the locking blocks 541 are disposed at intervals on a side of the second push plate 522 facing away from the second fixing plate 532.
