Furthermore, the lifting plate is fixedly connected with a directional rod towards one side of the movable transverse plate, a sliding groove is formed in the movable transverse plate, and one end of the directional rod is located in the sliding groove and slides.

Through adopting above-mentioned technical scheme, when the screw drove the lifter plate and goes up and down, the rotation that direction of rotation and screw are unanimous also can take place for lifter plate self, and directional lever and spout butt, the spout lateral wall has the power in opposite direction to the directional lever to make first sawtooth portion and second sawtooth portion meshing in-process need not to hold the lifter plate again.

Furthermore, locking Assembly includes T shape round pin, first through-hole has been seted up on the activity diaphragm, fixed diaphragm orientation second through-hole has been seted up to activity diaphragm one side, T shape round pin passes first through-hole and second through-hole in proper order.

Through adopting above-mentioned technical scheme, realize fixing of the relative position of fixed diaphragm and activity diaphragm.

Furthermore, a plurality of second through holes are formed in the length direction of the fixing transverse plate.

Through adopting above-mentioned technical scheme, T shape round pin passes the second through-hole of different positions on the fixed diaphragm length direction, can be according to the selection of the big or small adjustment second through-hole of live body, realizes the clamp of the live body of equidimension getting.

Furthermore, a clamping groove is formed in one side, away from the fixed transverse plate, of the movable transverse plate, and the head of the T-shaped pin is abutted to the groove wall of the clamping groove.

By adopting the technical scheme, the possibility that the T-shaped pin falls down from the movable transverse plate can be effectively reduced.

Furthermore, the head of the T-shaped pin is fixedly connected with a pulling block.

Through adopting above-mentioned technical scheme, carry and draw the piece, can be quick take out T shape round pin from the joint inslot, increase the convenience.

To sum up, the utility model discloses a following at least one useful technological effect:

1. the locking assembly can ensure that the relative positions of the fixed transverse plate and the fixed transverse plate are locked when the living body is clamped, so that the fixed transverse plate and the movable transverse plate do not move back to back due to human reasons, and the possibility that the living body falls off from the space between the upper tong head and the lower tong head is reduced;

2. through the arrangement of the screw, the lifting plate, the first sawtooth part and the second sawtooth part, the lifting plate can be controlled to lift through the screw, so that the first sawtooth part is meshed with the second sawtooth part, and the relative position of the movable transverse plate and the fixed transverse plate is locked;

3. through the setting of directional lever and spout, the directional lever stretches into and can restrict the rotation of lifter plate self in the spout to guarantee that the lifter plate only goes up and down and does not take place rotatoryly.
