[0031] The utility model will be described in detail below with reference to the accompanying drawings:
[0032] Example: As shown in the attached Figures 1 to 12As shown, the absorbable ligation clamp for preventing disengagement comprises a clamp head 1, a movable clamp 1-1, a fixed clamp 1-2, a positioning block 1-3, a sleeve 2, an external thread 2-1, an inner tube 3, a hook 3-1, a fixed column 3-2, a fixed block 3-3, a push block 3-4, a trigger 4, a flange 4-1, a limit spring 4-2, a trigger pin 4-3, a buckle 5, a limit block 5-1, a buckle pin 5-2, a front handle 6, a trigger mounting groove 6-1, a buckle mounting groove 6-2, a front positioning pin 6-3, a through hole 6-4, a first rotating pin hole 6-5, a rear handle 7, a limit groove 7-1, a mounting groove 7-2, a rear positioning pin 7-3, a second rotating pin hole 7-4, a limit pin 7-5, a sliding groove 7-6, a return spring 8, a sliding limit member 9, a left sliding groove 9-1, a right sliding groove 9-2, a push-pull member 10 and a rotating pin 11.
[0033] Reference Figure 1 , 2 3. A clamp head 1 is provided at the front end of the sleeve 2. The clamp head 1 includes a movable clamp 1-1 and a fixed clamp 1-2, wherein the fixed clamp 1-2 is welded and fixed to the front end of the sleeve 2, and the movable clamp 1-1 is hingedly connected to the fixed clamp 1-2. An external thread 2-1 is provided at the rear end of the sleeve 2, so as to be threadedly connected with the through hole 6-4 provided at the upper part of the front handle 6. Preferably, a positioning block 1-3 is provided at the front end of the movable clamp 1-1, and the positioning block 1-3 can position and install the ligation clip, effectively preventing the ligation clip from accidentally falling off during the operation, improving the operation efficiency, and reducing the operation risk.
[0034] like Figure 2 , 3 As shown, the front end of the inner tube 3 passes through the front handle 6 and the sleeve 2 in sequence, and then is connected to drive the movable clamp 1-1 through the push-pull member 10. The front end of the inner tube 3 is provided with a hook 3-1, which can be connected to the push-pull member 10 in a slot-like manner. Figure 4 , 11 As shown, a mounting groove 7-2 is provided at the upper end of the rear handle 7 at a position corresponding to the through hole 6-4, and the fixing block 3-3 at the rear end of the inner tube 3 can be inserted into the mounting groove 7-2. At the same time, limiting grooves 7-1 are provided on both sides of the mounting groove 7-2, so that the fixing columns 3-2 on both sides of the fixing block 3-3 are inserted into the limiting grooves 7-1, so that the rear end of the inner tube 3 can be detachably mounted on the rear handle 7. At the same time, a limiting pin 7-5 is provided on the rear handle 7 at the lower part of the limiting groove 7-1, which can resist the fixing block 3-3. A pushing block 3-4 is provided on the outer wall of one section of the inner tube 3 that penetrates the through hole 6-4.
[0035] Reference Figure 5 , 10A trigger installation slot 6-1 is provided on the front handle 6. After the trigger 4 is inserted into the trigger installation slot 6-1, it is hinged to the front handle 6 through the trigger pin 4-3. One end of the trigger 4 is pressed against the inner wall of the front handle 6 through the limit spring 4-2. The limit spring 4-2 provides a rebound force to the trigger 4. The other end of the trigger 4 is pressed against the push block 3-4. Fig. 9 , 10 As shown, a buckle installation groove 6-2 is provided through the front handle 6, and the buckle 5 is inserted into the buckle installation groove 6-2 and is rotatably connected with the front handle 6 through the buckle pin 5-2. A flange 4-1 is provided on the side of the trigger 4 facing the buckle 5, and when the trigger 4 rotates, the flange 4-1 and the surface of the buckle 5 are always meshed and transmitted through the wedge-shaped teeth, that is, no matter how the trigger 4 rotates, the flange 4-1 and the wedge-shaped teeth of the buckle 5 can always be engaged, thereby stabilizing the opening and closing degree of the pliers head 1. Preferably, a limit block 5-1 is provided at the end of the buckle 5 away from the trigger 4, which is used to abut against the rear handle 7 to limit the rotation range of the trigger 4. The limit block 5-1 will clamp the rear handle 7 when the trigger 4 reaches the limit activity position, preventing the trigger 4 from continuing to move, and preventing the trigger 4 from being damaged due to excessive force.
[0036] like Fig.10 , 11 As shown in Figures 1 and 12, a sliding groove 7-6 is provided at a position corresponding to the buckle installation groove 6-2 on the rear handle 7, and a left sliding groove 9-1 is provided at the left end of the sliding limiter 9, which can be inserted into the buckle installation groove 6-2, and the left sliding groove 9-1 cooperates with the front positioning pin 6-3 installed on the front handle 6 to achieve sliding limitation. A right sliding groove 9-2 is provided at the right end of the sliding limiter 9, which can be inserted into the sliding groove 7-6, and the right sliding groove 9-2 cooperates with the rear positioning pin 7-3 installed on the rear handle 7 to achieve sliding limitation.
[0037] Further, a first rotation pin hole 6-5 is provided at the lower end of the front handle 6, and a second rotation pin hole 7-4 is provided at the lower end of the rear handle 7. After the lower ends of the front handle 6 and the rear handle 7 are slot-matched, a rotation pin 11 is inserted, so that the front handle 6 is rotatably connected with the rear handle 7. Preferably, a return spring 8 is installed between the front handle 6 and the rear handle 7, and the return spring 8 provides a rebound force to the rear handle 7.
[0038] The working process of this utility model:
[0039] When the trigger 4 is pressed, the front end of the trigger 4 will push the push block 3-4, drive the inner tube 3 to move forward, and the wedge-shaped teeth on the flange 4-1 will push toward the buckle 5. Since the rear end of the inner tube 3 is connected to the rear handle 7, the rear handle 7 will move toward the front handle 6, and the front end of the inner tube 3 will drive the push-pull member 10 to close the pliers head 1 through the movable pliers 1-1. When the trigger 4 is released, the return spring 8 and the limit spring 4-2 will return the rear handle 7 and the trigger 4 to their original positions, the rear handle 7 will pull the inner tube 3, the inner tube 3 will pull the push-pull member 10, and the pliers head 1 (movable pliers 1-1) will open immediately.
[0040] When the trigger 4 reaches the limit movable position, the limit block 5 - 1 will block the rear handle 7 to stop the trigger 4 from continuing to move, thereby preventing the trigger 4 from being damaged due to excessive force.
[0041] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
