(2101) The pin mounting hole (2102) is arranged at two ends of the pin (23) in the pin mounting hole (2102), the pin (23) is provided with front and rear stay positions in the pin mounting hole (2102), and a bulge for limiting the pin (23) to move and change between the two stay positions is arranged in the pin mounting hole (2102); the two stay positions are a front opening and closing position and a rear locking position respectively, the rear end of the forceps cup (24) is provided with a locking protrusion (2404), and the release locking groove (2101) comprises a locking groove section and a release groove section which are communicated with each other; when the pin (23) is positioned at the locking position, the two forceps cups (24) are closed and locked, and the locking protrusions (2404) on the forceps cups (24) are positioned at the locking groove sections of the unlocking locking grooves (2101); when the pin (23) is in the open and close position, the two forceps cups (24) can be opened or closed, and the locking protrusions (2404) on the forceps cups (24) are positioned at the release groove sections of the release locking grooves (2101). Therefore, the pin can move and shift across the bulge to realize the movement and transposition between two stay positions under the condition of larger external force, the pin can be locked in position, the locking of the clamping state of the forceps cup is realized by releasing the matching of the locking groove and the locking bulge, the firm and reliable locking of the clamping head after the clamping head is clamped is realized through double locking, and the loosening or slipping of tissues out of the clamping head after the clamping head is clamped is avoided.
Preferably, one end of a release groove section of the release locking groove (2101) is open, the other end of the release groove section is communicated with the locking groove section, and two ends of the locking groove section are closed.

The problem that the muscle layer cannot naturally fall off can be effectively solved by arranging the grooves on the forceps cups. The groove structure can properly weaken the strength of the forceps cup, when a suture wound reaches a certain time (the wound is healed at the moment), the forceps cup gradually loses the closing force of the head end of the forceps cup through the creep of the material of the forceps cup and the weakening of the strength of the groove, and the effect of natural falling is achieved.
