[0011] Furthermore, a connecting head is provided at the rear of the lower clamp head, and the connecting head is provided with a channel, and the connecting rod passes through the channel of the connecting head and is hinged to the rear of the upper clamp head.

[0012] Furthermore, when the upper clamp head swings to contact the lower clamp head, the hook portion is located on the outer side of the upper clamp head.

[0013] Furthermore, in order to properly accommodate the cut tissue, the lower forceps head is provided with at least one tissue stop pin, and the tissue stop pin passes through the tissue accommodating cavity.

[0014] Furthermore, the hook portion is pointed, and both ends thereof are connected with the front end of the blade mating surface in a balanced transition.

[0015] The utility model also provides a sampling pliers, comprising the above sampling pliers head.

[0016] After adopting the above technical solution, the utility model has the following beneficial effects:
