[0002] Needle-nosed pliers are one of the typical tools that use the principle of levers. They are generally operated with the right hand. When using them, hold the two handles of the needle-nosed pliers to start clamping or cutting. When the current needle-nosed pliers need to be clamped without cutting the wire, the pliers need to be held by hand, otherwise the clamping between the upper and lower pliers of the needle-nosed pliers will loosen, which is too inconvenient when the worker needs to take other tools. In addition, when cutting the wire, the buffering and reset effects between the upper and lower pliers are too poor, resulting in deformation of the upper or lower pliers after repeated use.

[0003] In view of the above technical problems, a needle-nosed pliers with a stable clamping effect is disclosed in the announcement number CN210938847U. When the lower pliers body and the upper pliers body are clamped, as the buffer balls collide with each other, the buffer balls squeeze the buffer springs, which can improve the buffering and resetting effect of the lower pliers body and the upper pliers body.

[0004] The above patent also has the following shortcomings: in actual use, it is necessary to continuously ensure the gripping force of the palm to achieve a stable clamping effect. Long-term gripping can easily cause unstable gripping force, resulting in loosening during clamping, making it impossible to perform other operations, and making it inconvenient for people to use. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a pair of needle-nosed pliers with a stable clamping effect, comprising a grip rod 1, a locking mechanism 2 for stable clamping is arranged at one end of the outer side of the grip rod 1, a limiting mechanism 3 for closing and preventing self-extension is arranged at one end of the grip rod 1, a reset mechanism 4 for resetting and unfolding is arranged at the inner side of the grip rod 1, a pliers body 5 is fixedly installed at one end of the grip rod 1, the locking mechanism 2 comprises a connecting seat 21, and the connecting seat 21 is fixedly installed at the outer side of the grip rod 1;

[0024] A connecting frame 22 is rotatably connected to the inner side of the connecting seat 21 , one end of the connecting frame 22 is threadedly connected to a threaded rod 23 , one end of the threaded rod 23 is movably mounted with a stop plate 24 , and the other end of the threaded rod 23 is fixedly mounted with a rotating handle 25 .

[0025] The addition of the locking mechanism 2 is used to achieve the clamping stability of the entire needle-nosed pliers when in use, thereby reducing the continuous gripping force applied by the user, thereby reducing the continuous output of the user's force and achieving a labor-saving effect.

[0026] In actual use:

[0027] First, the limit mechanism 3 needs to be removed, and then the grip rod 1 and the clamp body 5 will be opened according to the elastic push of the reset mechanism 4. Then, the grip rod 1 is held by hand. Since the grip rod 1 and the clamp body 5 are provided with two groups, they will be staggered in the actual use process. When the output force reaches the preset effect, the connecting frame 22 is manually rotated to rotate the connecting frame 22 to the outside of the two groups of grip rods 1, such as Figure 1, and then rotate the threaded rod 23. At this time, the threaded rod 23 will push the push plate 24 to move horizontally until the push plate 24 contacts the grip rod 1 and forms an extrusion limit to release the force applied when gripping. At this time, other operations can be performed without loosening of the gripping force. At the same time, it saves effort and has the advantage of stable clamping.

[0028] The threaded rod 23 and the support plate 24 are connected in two ways. The first way is to add a bearing seat between the two for rotational connection. The second way is to add a hinge and a bearing seat. The hinge is located on one side of the support plate 24, and the bearing seat is installed on one side of the hinge. The bearing seat is then connected to the threaded rod 23, thereby forming a rotational connection in different directions between the threaded rod 23 and the support plate 24.

[0029] Preferably, the limiting mechanism 3 includes an adapter component and an insertion component. The adapter component is arranged at one end of the handle 1, and the insertion component is located inside the adapter component.

[0030] like Figure 3 and 4 As shown, the adapter assembly includes a slide hole 31 and a slot 35, and the slide hole 31 and the slot 35 are both opened at one end of the handle 1, which is convenient for connecting the insertion assembly, thereby completing the limiting work after closing.

[0031] like Figure 4 As shown, the insertion component includes a slide rod 32, which is slidably connected to the inside of the slide hole 31, and an insert block 34 is inserted into the inside of the slot 35, which is conducive to the matching component to perform insertion-type limiting on the handle 1.

[0032] like Figure 4 As shown, a connecting plate 33 is fixedly installed at one end of the plug block 34 and the slide rod 32, and a wire stripping groove 6 is provided on the inner wall of the clamp body 5. The connecting plate 33 facilitates pushing and pulling the slide rod 32 and the plug block 34, and the wire stripping groove 6 can assist people in stripping the wires.

[0033] like Figure 1 and 4 The figure shows the closed state. When the handle 1 needs to be closed and the position limiting operation is performed, the connecting plate 33 is pushed, and the connecting plate 33 drives the slide bar 32 to slide inside the slide hole 31, and the insert block 34 is directly inserted into the slot 35. At this time, the spring 42 is compressed, so that there is a thrust between the two sets of handles 1, so that the insert block 34 is stably located inside the slot 35 and will not fall off.

[0034] When the needle-nosed pliers are needed, the gripping rod 1 is manually held and a slight gripping force is applied, and then the connecting plate 33 is pulled, and the connecting plate 33 is used to drive the sliding rod 32 to slide outward inside the sliding hole 31. At the same time, the plug block 34 is disengaged from the slot 35 to complete the operation of releasing the limit on the gripping rod 1, and the connecting plate 33 is rotated to drive the plug block 34 from the horizontal state to the vertical state.

[0035] A threaded hole is provided at the center of one end of the connecting frame 22 , and the inner wall of the threaded hole is threadedly connected to the threaded rod 23 . The threaded hole facilitates the threaded connection between the connecting frame 22 and the threaded rod 23 .

[0036] Furthermore, the reset mechanism 4 includes a fixed block 41 and a spring 42. The fixed block 41 is fixedly mounted on the inner wall of the grip 1, and the spring 42 is welded to the inner wall of the fixed block 41. The fixed block 41 is convenient for installing the spring 42. The elasticity of the spring 42 is utilized to push the two sets of grips 1 so that the spring 42 is compressed after being gripped. When the grips 1 are released, the two sets of grips 1 are directly spread out according to the reaction force of the spring 42, so that they are automatically unfolded for people's use.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
