[0006] The top of the suction cup is equipped with the fixed ring, and the fixed ring and the suction cup form a rotating groove, the rotating groove is equipped with the rotating block which is rotatably connected, and the connecting block is arranged on the rotating block.

[0007] The traction rope is equipped with the connecting head, the connecting block is equipped with the connecting hole, and the connecting hole is screw connected with the connecting head.

[0008] The connecting rod is equipped with the rotating ring which is rotatably connected, and the fixed block is arranged on the rotating ring.

[0009] The handle is equipped with the anti-skid pad made of rubber.

[0010] The negative pressure pipe is equipped with the one-way valve for pressure relief.

[0011] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:

[0012] The connecting block and the traction rope are symmetrically arranged at the bottom of the suction disc, the fixed block for limiting the traction rope is arranged on the connecting rod, so that the operator can pull the suction disc to make the suction disc swing slightly left and right when pulling out the fetus, and the speed of pulling out the fetus is accelerated, the speed of the operator pulling out the fetus is effectively improved, and the adjustment of the body position of the fetus during the operation process is reduced.
