1. A bipolar coagulation forceps, the bipolar coagulation forceps comprising:

the power supply comprises a support piece, a clamp frame and two electrode plates which are respectively and electrically connected with a positive electrode and a negative electrode of a power supply; the clamp comprises a connector and two clamp arms connected with the connector, the connector is in sliding fit with the support piece, the two electrode plates are respectively installed on the two clamp arms, and when the connector is opposite to the support piece in sliding, the two clamp arms drive the two electrode plates to rotate to be closed or opened.

2. A bipolar electrocoagulation clamp according to claim 1, wherein:

at least one of the two clamp arms is provided with an elastic part which is used for enabling the two electrode plates to have a splayed movement trend.

3. A bipolar electrocoagulation clamp according to claim 1, wherein:

the connector with support piece is relatively fixed in circumference around predetermineeing the axis, wherein, predetermine the axis and be on a parallel with the sliding direction of connector.

4. A bipolar electrocoagulation clamp according to claim 1, wherein:

the support piece is provided with at least one avoidance groove, and when the clamp arm drives the two electrode plates to be opened, the clamp arm can be embedded into the avoidance groove to increase the opening angle of the two electrode plates.

5. A bipolar electrocoagulation clamp according to claim 1, wherein:

the supporting piece is provided with a first limiting structure and a second limiting structure, the first limiting structure is used for preventing the clamp frame from being separated from the supporting piece along a first direction, and the second limiting structure is used for limiting the sliding range of the clamp frame along a second direction opposite to the first direction.

6. A bipolar electrocoagulation clamp according to claim 1, wherein:

and an insulating layer is arranged between each electrode plate and the corresponding clamp arm.

7. A bipolar electrocoagulation clamp according to claim 6, wherein:
