Description

Technical Field

[0001] This utility model relates to the technical field of carp pliers, specifically to a carp pliers with multiple adjustable positions. Background Technology

[0002] Most carp pliers on the market currently use the traditional single or double gear adjustment method, with only two or three fixed gears. They cannot achieve stepless adjustment, which means that when a smaller gear is selected, the jaws cannot close properly, causing slippage. When a larger gear is selected, the jaw angle is too large, the clamping force is dispersed, and the workpiece surface is easily damaged. Furthermore, manual adjustment is required repeatedly during operation, which is time-consuming and laborious, and cannot meet the needs of fast-paced work. Utility Model Content

[0003] This invention proposes a carp pliers with multiple adjustable gears that can be quickly switched between, and is simple and convenient to operate.

[0004] Therefore, the technical solution adopted is as follows:

[0005] A multi-position, quickly adjustable carp pliers includes a fixed handle, a sliding handle, and a connecting shaft. The fixed handle has an adjustment groove, and the sliding handle has an adjustment hole corresponding to the adjustment groove. A snap-fit ​​rack is fixed to the side wall of the adjustment hole, arranged along the opening and closing direction of the jaws. The adjustment hole has a snap-fit ​​pawl inside. The connecting shaft is fixed to the fixed handle and passes through the adjustment groove, the snap-fit ​​pawl, and the adjustment hole in sequence, and is locked with a nut. The snap-fit ​​pawl is rotatably connected to the connecting shaft. A torsion spring is connected between the snap-fit ​​pawl and the adjustment groove. The torsion spring forces the snap-fit ​​tip of the snap-fit ​​pawl to abut against the snap-fit ​​rack around the connecting shaft.

[0006] A further technical solution is that the latching pawl has a quadrilateral structure, and the other three corners, excluding the latching tip, are, in clockwise order, abutting angle one, abutting angle two, and abutting angle three. When the latching tip of the latching pawl abuts against the latching rack, abutting angle two simultaneously abuts against the side wall of the adjustment hole. When the latching tip of the latching pawl rotates and disengages from the latching rack, abutting angle one and abutting angle three abut against the side wall of the adjustment hole.

[0007] A further technical solution is that both the adjusting groove and the snap-fit ​​pawl are provided with torsion spring leg holes, and the two ends of the torsion spring are respectively inserted into the two torsion spring leg holes for fixation.

[0008] A further technical solution is that the thickness of the latching pawl is equal to the depth of the adjustment hole.

[0009] A further technical solution is that when the jaws are fully closed, the adjusting groove and the adjusting hole coincide.

[0010] The working principle and beneficial effects of this application are as follows:

[0011] 1. By adjusting the connection position of the latching pawl and the latching rack, the jaw size can be infinitely adjusted to correspond to different jaw sizes.

[0012] 2. During the jaw adjustment process, simply rotate the fixed handle and the sliding handle outward with both hands to overcome the spring force of the torsion spring, so that the locking pawl disengages from its original position on the locking rack and slides to the desired new position. Then rotate the fixed handle and the sliding handle inward to reset the locking pawl and lock it with the locking rack. The whole process is simple to operate and the action is smooth, which improves the efficiency of the carp pliers when adjusting the jaws and increases the overall continuity of the work.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-6As shown, a multi-position adjustable carp pliers includes a fixed handle 1, a sliding handle 2, and a connecting shaft 3. The fixed handle 1 has an adjustment groove 11, and the sliding handle 2 has an adjustment hole 21 corresponding to the adjustment groove 11. A locking rack 211, arranged along the opening and closing direction of the pliers, is fixed to the side wall of the adjustment hole 21. A locking pawl 4 is located inside the adjustment hole 21. The connecting shaft 3 is fixed to the fixed handle 1 and passes sequentially through the adjustment groove 11, the locking pawl 4, and the adjustment hole 21, and is locked by a nut 5. The locking pawl 4 is rotatably connected to the connecting shaft 3. A torsion spring 6 connects the locking pawl 4 and the adjustment groove 11, and the torsion spring 6 forces the locking tip 41 of the locking pawl 4 to abut against the locking rack 211 around the connecting shaft 3.

[0023] When adjusting the opening size of the carp pliers, grasp the fixed handle 1 and the sliding handle 2 with both hands and rotate them outward around the connecting shaft 3. Figure 2 As shown, since the pawl 4 can rotate to a certain extent in the adjustment hole 21, when the applied force is greater than the elastic force of the torsion spring 6, the pawl 4 will rotate out of the restriction of the pawl rack 211, and thus be able to be acted upon by the connecting shaft 3. As the fixed handle 1 slides in the adjustment hole 21, after selecting the corresponding locking position according to the required jaw size, the fixed handle 1 and the sliding handle 2 are rotated in the opposite direction to make the tip of the pawl 4 re-lock into the pawl rack 211. The torsion spring 6 continues to work to make the tip of the pawl 4 press against the pawl rack 211 for fixation. The whole process is simple and quick to operate. You only need to use both hands to first open the fixed handle 1 and the sliding handle 2 to make the pawl 4 get rid of the force of the torsion spring 6, and then select a new locking position to close the fixed handle 1 and the sliding handle 2. The adjustment is smooth and easy to operate.

[0024] The latching pawl 4 has a quadrilateral structure. Besides the latching tip 41, the other three corners, clockwise, are abutment angle one 42, abutment angle two 43, and abutment angle three 44. When the latching tip 41 of the latching pawl 4 abuts against the latching rack 211, abutment angle two 43 simultaneously abuts against the side wall of the adjusting hole 21. When the latching tip 41 of the latching pawl 4 rotates and disengages from the latching rack 211, abutment angle one 42 and abutment angle three 44 abut against the side wall of the adjusting hole 21. (See reference...) Figure 1 At this time, the locking tip 41 is pressed against the locking rack 211 by the torsion spring 6, and the locking angle 43 is also pressed against the side wall of the adjusting hole 21 to form a stable structure. Because this is the stable working state of the jaws, the jaws will be clamped during work, so the locking pawl 4 will be subjected to a clockwise rotational force around the connecting shaft 3. No matter how large the force is, the positions of the connecting shaft 3, the locking pawl 4 and the adjusting hole 21 will remain unchanged, ensuring the working strength of the carp pliers. Conversely, refer to [the original text]. Figure 2At this point, the jaw size needs to be adjusted, and a counterclockwise force is applied to the locking pawl 4 around the connecting shaft 3. The locking tip 41 disengages from the locking rack 211. Also under the action of the torsion spring 6, the locking pawl 4 will rotate clockwise. However, after rotating to the disengaged position, the first abutment angle 42 and the third abutment angle 44 will abut against the side wall of the adjustment hole 21, and the locking pawl 4 will no longer rotate. The purpose is to ensure that the disengaged position of the locking tip 41 is constant and the disengagement angle is not too large, so that the locking can be quickly reset after the jaw size adjustment is completed.

[0025] like Figures 4-6 As shown, both the adjusting groove 11 and the locking pawl 4 have torsion spring leg holes 61, and the two ends of the torsion spring 6 are respectively inserted into the two torsion spring leg holes 61 for fixation. The thickness of the locking pawl 4 is equal to the depth of the adjusting hole 21, thereby making the rotational connection between the adjusting groove 11, the locking pawl 4, and the adjusting hole 21 smoother and more stable. Furthermore, when the jaws are fully closed, the adjusting groove 11 and the adjusting hole 21 coincide, improving the overall structural coordination.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
