Specifically, the embodiment converts the rotation of the trigger 200 into the extension and contraction of the steel wire fixed rod 320 through the connecting rod one 410, the connecting rod two 420 and the connecting rod three 430, and the structure is compact. Thus, the structure of the present application is small and compact.
[0048] Further, the connecting rod one 410 is two, and the two connecting rod ones 410 are arranged on the two sides of the connecting rod two 420. The connecting rod three 430 is two, and the two connecting rod threes 430 are arranged on the two sides of the connecting rod two 420. Specifically, the embodiment makes the operation of the connecting assembly 330 more stable and reliable.
[0049] Further, the self-locking part 520 is provided with self-locking teeth 521, and the side of the trigger 200 facing the self-locking part 520 is provided with trigger teeth 220 matched with the self-locking teeth 521. Specifically, the embodiment enables the trigger teeth 220 to push away the self-locking teeth 521 when the trigger 200 is rotated clockwise, so as not to affect the rotation of the trigger 200, and when the rotation of the trigger 200 is stopped, the trigger teeth 220 are engaged with the self-locking teeth 521, so as to more reliably limit the rotation of the trigger 200 under the action of the reset part 530, thereby realizing the self-locking of the closing of the upper plier head 340 and the lower plier head 350.
[0050] Further, the top of the shell 100 is provided with a through hole 120 communicating with the inside thereof; one end of the main body 510 extends to the upper side of the shell 100 through the through hole 120. Specifically, it is convenient to drive the self-locking part 520 to rotate by pulling the main body 510 extending out of the shell 100, and the operation is convenient and fast.
[0051] Further, the part of the main body 510 extending out of the shell 100 is connected with an unlocking button 550, and the unlocking button 550 is inclined downward from the front end to the tail end. Specifically, the embodiment can be pulled by the unlocking button 550, which is convenient to operate.
[0052] Further, the main body 510 is in S-shaped structure, the middle part of the main body 510 is rotationally connected with the shell 100 through the unlocking button pin 560; the unlocking button 550 and the self-locking component 520 are separately arranged on the front and back sides of the unlocking button pin 560; the waist-shaped hole 511 is arranged on the main body 510, and the connecting hole is arranged on the self-locking component 520; the waist-shaped hole 511 and the connecting hole are hingedly connected through the self-locking tooth pull rod pin 570. Specifically, the embodiment can more labor-savingly realize the rotation of the self-locking component 520 by pulling the unlocking button 550.
[0053] Further, the self-locking component 520 is provided with a U-shaped groove 522, and the reset member 530 is a reset torsional spring, one end of the reset torsional spring being inserted into the U-shaped groove 522. Specifically, the embodiment realizes the assembly of the reset torsional spring and the self-locking component 520 by inserting one end of the reset torsional spring into the U-shaped groove 522, and quick assembly can be realized.
[0054] Further, the bottom of the trigger 200 is provided with an arc-shaped groove 230 for hand holding. Specifically, the arc-shaped groove 230 is in close contact with the fingers of the human body, and the comfort of the user is improved.
[0055] Further, the shell 100 comprises a first handle shell 130 and a second handle shell 140, and the first handle shell 130 and the second handle shell 140 are fixedly connected through the fixing screw 150. Specifically, the first handle shell 130 and the second handle shell 140 are butted to form the shell 100, and assembly is simple.
[0056] The working process of the application is as follows:
[0057] The upper plier head 340 is closed: when the application is working, the doctor holds the shell 100, and then holds the trigger 200 with fingers, the trigger 200 rotates clockwise around the trigger rotation pin 210, thereby driving the connecting rod one 410 to move, the movement of the connecting rod one 410 drives the connecting rod two 420 to rotate around the connecting rod two rotation pin 422, the rotation of the connecting rod two 420 drives the connecting rod three 430 to move to the end, the movement of the connecting rod three 430 to the end drives the steel wire rope fixing rod 320 to move to the end along the guide groove in the plier head connecting rod 310, thereby tightening the steel wire rope 331, and further pulling the upper plier head 340 to close. When the trigger 200 rotates clockwise around the trigger rotation pin 210, the trigger 200 rotates against the self-locking component 520, thereby compressing the reset torsional spring.
[0058] Self-locking: after the upper plier head 340 is closed, when the trigger 200 is released, the trigger 200 has a tendency to rotate counterclockwise around the trigger rotation pin 210, but because the trigger teeth 220 on the trigger 200 are in close contact with the self-locking teeth 521, and the self-locking component 520 remains in the original position under the action of the reset torsional spring and does not move, thereby clamping the trigger 200 in a position and preventing the trigger 200 from rotating, thereby realizing the self-locking of the closed upper plier head 340.
[0059] Unlock reset: when the doctor needs to unlock, just press the unlock button 550, the unlock button 550 will lift the self-locking part 520, so that the trigger tooth 220 and the self-locking tooth 521 are separated, so that the trigger 200 rotates counterclockwise to drive the steel wire 331 to be loose, so that the upper jaw 340 is reset.
[0060] Obviously, the above embodiments are only examples for the purpose of clarity, and are not limiting of the embodiments. Based on the above description, other different forms of changes or variations can be made by those of ordinary skill in the art. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
