The second guide surface 309 is provided on the outer circumferential wall, faces the fixed end 401 of the tie rod 4, and faces the locking groove 303, and may be a flat surface or a curved surface. It is mainly used for the movable end 402 in the locking groove 303 to be able to slide toward the pressing block 311 when the slider 3 moves toward the fixed end 401.
In the use process, if the movable end 402 of the pull rod 4 is located in the release groove 307, the user pushes the slider 3 to approach the fixed end 401, so that the slider 3 is pressed into the first handle 1 along the chute 103, the movable end 402 of the pull rod 4 slides to the first stopping position 305 along the first guiding surface 308, the operator releases the slider 3, the movable end 402 of the pull rod 4 enters the locking groove 303, and when the movable end 402 of the pull rod 4 is clamped with the locking groove 303, the slider 3 is located in the locking position of the chute 103. The user then presses the slider 3 again and the movable end 402 of the pull rod 4 slides along the second guide surface 309 to the second stop position 306, after which the slider 3 is released and the pull rod 4 returns to the release slot 307, whereupon the slider 3 is in the release position of the chute 103.
Alternatively, in order to facilitate the movement of the movable end 402 of the pull rod 4 into the locking groove 303, in this embodiment, the outer circumferential wall is provided with a third guiding surface 310, and the second guiding surface 309 and the third guiding surface 310 form a sharp corner 304 protruding towards the locking groove 303. Specifically, the movable end 402 of the pull rod 4 is guided into the locking groove 303 by the third guiding surface 310, and in addition, the top end of the sharp corner 304 is staggered from the pit of the locking groove 303, so that when the sliding block 3 is pressed again, the movable end 402 of the pull rod 4 can slide into the second stopping position 306 along the second guiding surface 309 and smoothly reach the releasing groove 307.
Alternatively, in one embodiment provided in the present application, the first handle 1 is provided with a fixing base 104 fixed to the pull rod 4, and the fixing base 104 is located between the fixed end 401 and the movable end 402. In particular, the pull rod 4 has certain elasticity and is preferably made of spring steel materials. The fixing base 104 is located at the middle of the pull rod 4, so that the pull rod 4 is blocked to become bent when sliding in the sliding rail 301, and returns to the initial state under the requirement of self elasticity.
Further, on the basis of any one of the above embodiments, the locking assembly includes a stop plate 7, where an end portion of the stop plate 7 abuts against the slider 3, and a middle portion of the stop plate 7 is pivotally connected to the first handle 1 through a pivot 701, and the stop plate 7 is provided with an opening 702. The clamping strip 202 is positioned in the opening 702, and the clamping strip 202 is in an arc structure taking the hinge shaft 201 as a center. When the sliding block 3 moves along the sliding groove 103, the stop plate 7 rotates around the pivot mounting shaft 701 under the driving of the sliding block 3, and when the movable end 402 abuts against the locking groove 303, the opening 702 abuts against two opposite sides of the clamping strip 202.
Specifically, the opening 702 may be a groove structure provided on one side of the stopper plate 7, and preferably the opening 702 is a through hole penetrating the stopper plate 7 in the thickness direction.

In particular, the elastic member 6 may be a spring, one end of which is limited by the first handle 1 and the other end of which is connected to the stop plate 7. The elastic member 6 can indirectly drive the slider 3 to reset after the operator releases the slider 3. It can be understood that if the forceps are not provided with the elastic member 6, the slider 3 is fixedly connected with the stop plate 7, and the effect of controlling the reciprocating swing of the stop plate 7 can be still realized.
Optionally, referring to fig. 3 and 5, in an embodiment of the slider 3 provided herein for controlling the stop plate 7 to swing, the end portion of the slider 3 is provided with a bending strip 302, and the embodiment further includes a toggle knob 5 and a torsion spring 8 for driving the toggle knob 5 to rotate, where one end of the toggle knob 5 abuts against the stop plate 7, the other end abuts against the bending strip 302, and the middle portion is pivoted with the first handle 1.
Specifically, the toggle knob 5 can be driven by the torsion spring 8 and the sliding block 3, and the bending strip 302 pushes the toggle knob 5 to rotate and then the torsion spring 8 is pressed. When the pull rod 4 is in the locking groove 303, the toggle knob 5 is rotated, so that the toggle protrusion 501 on the other side of the toggle knob is separated from the stop plate 7, and the stop plate 7 rotates under the action of the elastic piece 6, so that the clamping strip 202 is in clamping fit with the opening 702. When the pull rod 44 enters the release groove 307 from the locking groove 303, the toggle knob 5 rotates in the opposite direction to the locking direction under the action of the torsion spring 8.
In the actual assembly process, the toggle knob shaft 502 can be arranged on the toggle knob 5, the first handle 1 is provided with the shaft groove 102, and the toggle knob shaft 502 is matched with the shaft groove 102 to realize the pivot joint of the toggle knob 5 and the first handle 1.
