As the utility model discloses a preferred technical scheme, the outside slip of dead lever has the handle that pushes away, pushes away the handle and is connected with the movable rod, pushes away the handle and is the loop configuration.

As the preferred technical scheme of the utility model, push away and be connected through the connecting seat between handle and the movable rod.

As the utility model discloses an optimal technical scheme is equipped with on the dead lever and is used for the gliding spout of connecting seat.

As an optimal technical proposal of the utility model, the surface of the push handle is provided with anti-skid lines.

As the utility model discloses an optimal technical scheme, the movable rod be equipped with the scale on the surface.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model pushes the movable rod out of the fixed rod by pushing the push handle, so that the two forceps heads are separated and opened, the traditional forceps are prevented from being opened and closed by the elasticity of metal and the finger force of the fingers of a doctor, and the precise control of the doctor is facilitated by the pushing mode;

2. the utility model discloses be equipped with the scale on the surface at the movable rod, through the distance of separation between two tweezers heads of judgement that the scale can be accurate, improve the accuracy of operation.
