Description

Tool pliers structure improvement

This creation is about the improvement of a tool pliers structure, mainly for the improvement of the existing needle-nosed pliers on the clamped object, and through its structural design, it can be more stable and not slippery on the clamped object.俾 It can improve the smoothness and efficiency of its operations, and give better industrial utilization and practical value.

Pressing, commonly used needle-nosed pliers and other tool tongs, mainly using the fine-toothed plan of the jaws of the tongs to increase the frictional force during clamping, so that it can firmly hold the object while at the same time The predetermined position of the surface is further provided with a pair of arc concave clamping grooves, and the groove surface of the arc concave clamping groove is provided with a tooth pattern, and the shape of the arc concave clamping groove is used to clamp the object with a larger diameter.

However, in view of the structure of the needle-nosed pliers described above, the shape of the tip of the needle allows it to have a good grip stability and a limited space when the small-diameter object is held in a narrow space. Flexible operation inside, so that the operation can be carried out smoothly, but when it uses the arc concave groove of the proximal bolt portion to hold the object of larger diameter, it is limited by the angle of separation of the clamp head, and Under the influence of the arc of the arc concave groove, it is difficult to obtain a stable clamping effect, and it is easy to cause the object slippage during the operation, and the clamping position must be repeated, which is not only inconvenient and inconvenient. At the same time, it will affect the smoothness of its operations, resulting in low efficiency, it is necessary to try to solve the improvement.

In view of the fact that the needle-nosed pliers are used to hold objects of a relatively large diameter, there are many problems and disadvantages caused by insufficient grip stability and slippage, which indirectly affects the overall work efficiency, and the creator specializes in hand R&D design, which can give better practical value through structural improvement.

In order to improve the stability of the needle-nosed pliers when holding larger-sized objects, the design is mainly based on the original structure of the front-neck of the needle-nosed pliers. The corresponding "<"">" type of groove is provided in the part, and the clamping surface of the grooved groove is provided with a tooth pattern, and the sides are not unequally arranged, and the 俾 can be given a clamping When you have various types of objects, you can get a better grip effect with multi-point touch.

The tool pliers of the creation are designed according to the improved structure, so that the original clamp can be arranged through the front clamp, so that when the larger-diameter objects are clamped, the side clamps of the slots can be borrowed. The holding surface and the object obtain multi-point contact clamping, which can improve the stability of the clamping and avoid the problem of object slippage, thereby eliminating the inconvenience caused by the repeated clamping, thereby improving the working efficiency and practical value. .

Regarding the structural composition, technical means and effectiveness of this creation, we will further elaborate on the following examples with the following:

Referring to Figures 1 to 4, a preferred embodiment of the present invention is illustrated. The tool pliers shown in the figure are a needle-nosed pliers, and the structural design thereof is mainly composed of a dimorphic pliers (10) (20). Overlapping, each of the jaws (10) (20) is formed by a shank (11) (21) and a tapered tapered jaw (12) (22) extending from the front end thereof, respectively, and The shank (11) (21) and the nipple (12) (22) are not in a linear extending relationship, but are provided with a curved shaft portion (13) (23) as a referral, and The opposite faces of the equiaxed portions (13) (23) are recessed to have a thickness of only half, and the two jaw pieces (10) 20) can be relatively fitted by the shaft portions (13) (23). Overlap and complete the overlapping pivots of the two pliers (10) (20) with the shaft pin (1) through the set of axial holes (not labeled), and in the clamp handle (11) ( 21) Part of the plastic handle sleeve (14) (24) coated with a handle that enhances the grip and handle, thereby forming the basic functional structure of the needle-nosed pliers that can be opened and operated; Under the structure, in addition to the original fine-toothed (15) (25) of the two clamping heads (12) (22), in order to increase the clamping of the larger diameter The stability of the piece is created in the clamped (1) part of the clamping surface of the second clamp head (12) (22), and the corresponding "<" ">" type clamp groove (16) is provided. 26), the clamping faces of the slots (16) and (26) are provided with a tooth pattern (not numbered), and the sides are not unequally arranged (the length ratio is preferably 7:3) The shape of the groove (16) (26) is matched with the groove of the clamping surface thereof, so that it can form a multi-touch when holding the object (30) (especially the cylindrical object). Achieve a stable clamping effect to improve the stability of the work and improve the problems and lack of the same kind of similar items; That is, from the above description, it can be seen that the solution provided by the present invention for the problem of the use of the tool pliers such as the conventional needle-nosed pliers is predetermined under the existing functional structure through the jaws of the jaws. The "<" ">" type clamps installed in the parts contain the groove type plan, so that even when holding various types of objects with larger diameters, you can use the sides and objects of the groove to obtain more points. The touch-type relationship can make the overall clamping effect more stable, avoiding the problem of slipping off during the operation and constantly re-clamping, making the operation smoother and relatively improving the whole The efficiency of the work, compared with the conventional problem that the needle-nosed pliers are difficult to firmly hold the large-diameter objects and the derivative problems, the structural improvement design made by this creation can indeed give better industrial utilization and practical value; Summarizing the above description, the tool clamp structure of the present invention is improved, and the structure of the clamp head portion is designed to make it more stable than the original object clamping function, and for the clamping of the larger-size object, a more stable clip can be obtained. Effective , Solve a similar article entirely conventional ideal of perfect is missing, the whole, the industry is indeed excellent usability and practical value, after all, a good honest, distinguished by innovative design, Yuan filed a patent application in accordance with law.
