Description

Technical Field

[0001] The utility model relates to the technical field of hardware tools, in particular to a novel opening support mechanism. Background Art

[0002] Punching pliers are tools for punching holes in sheet materials such as leather, paper, thin metal, and plastic. Existing punching pliers consist of a handle, a clamp base, and a punching needle. The handle controls the movement of the clamp base, and a simple lever principle is used to punch holes in the material.

[0003] Because existing punching pliers utilize a basic lever principle, shorter handles facilitate one-handed operation, but require more effort to punch holes and may not penetrate the material. Longer handles, while less laborious, are less practical for one-handed use. Furthermore, different methods of securing the pliers base to the handle can significantly alter the performance. To address these issues, we have developed a new punching support mechanism. Utility Model Content

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0024] The novel opening support mechanism disclosed in the utility model is mainly used in the scenario of the novel opening support mechanism.

[0025] Reference Figures 1 to 4 A novel opening support mechanism includes: a bottom membrane supporting force front arm 1 and a bottom membrane supporting force rear arm 2, the bottom of the bottom membrane supporting force front arm 1 is fixedly connected to the top of the bottom membrane supporting force rear arm 2, and a lower handle 3 and an upper handle 19 are respectively provided on both sides of the bottom membrane supporting force rear arm 2, and a punch needle bearing supporting force rear arm 17 is provided on the top of the lower handle 3, and an opening component is provided on the outer side of the bottom membrane supporting force front arm 1;

[0026] The opening assembly includes a shell 6, a notch 7 is formed on one side of the shell 6, the interior of the notch 7 is slidably connected to the outer side of the bottom membrane supporting force forearm 1, a punching slot 13 is formed on one side of the shell 6, a through slot 12 is formed inside the punching slot 13, a fixing block 8 is provided on the outer side of the shell 6, a groove 9 is formed on one side of the fixing block 8, the interior of the groove 9 is slidably connected to the outer side of the shell 6, and a mounting hole 10 is formed on one side of the fixing block 8;

[0027] A punching needle 15 is slidably connected to the interior of the through slot 12. A bearing 14 is provided on one side of the punching needle bearing supporting the force-generating rear arm 17. The bottom of the punching needle 15 abuts against the top of the bearing 14. A spring 16 is provided on the outside of the punching needle 15.

[0028] Fixing screws 11 are respectively provided between the bottom membrane supporting force front arm 1, the housing 6, the fixing block 8, the bearing 14 and the punch needle bearing supporting force rear arm 17;

[0029] Joint fixing screws 18 are respectively provided between the bottom membrane supporting force front arm 1, the bottom membrane supporting force rear arm 2, the lower handle 3, the upper handle 19 and the punch needle bearing supporting force rear arm 17.

[0030] In the above technical solution, considering that the existing punching pliers use the basic lever principle, a short handle is conducive to one-handed operation, but it is more laborious when punching and cannot penetrate the material. Although a long handle is not laborious, it is not easy for the user to use it with one hand. At the same time, the fixed connection method between the clamp seat and the handle is different, and the usage effect will be very different. In order to solve this problem, the specific operation is as follows: place the object in the through slot 12, and then hold the lower handle 3 and the upper handle 19 with your hands. The lower handle 3 and the upper handle 19 are close to each other, and the upper handle 19 drives the punch needle bearing support force arm 17 to rotate, so that the other end of the punch needle bearing support force arm 17 drives the bearing 14 to swing upward, so that the bearing 14 pushes the punch needle 15 to move upward, and the spring 16 is compressed and quickly extends from the inside of the through slot 12 to quickly open a hole in the object. Once you let go, the reverse push of the spring 16 drives the successful punch needle 15 to retreat into the through slot 12, and drives the punch needle bearing support force arm 17, the bottom film support force forearm 1 and the bottom film support force rear arm to reset. The operation is simple, and the force required for punching is smaller, thereby achieving a fast and efficient punching effect. The user operates with one hand, so that even when one-handed control is required, the punching can be completed smoothly, providing better flexibility of use.

[0031] Reference Figures 1 to 4 In a preferred embodiment, a protective plate 4 is fixedly connected to one side of the lower handle 3 and the upper handle 19, and through holes 5 are equidistantly provided between the lower handle 3, the upper handle 19 and the protective plate 4, and a pointed surface is provided on the top of the punching needle 15; the protective plate 4 has a certain elasticity, and the provision of the protective plate 4 can provide an additional gripping surface, thereby improving the user's feel when applying force, reducing hand slippage, and increasing comfort of use. A plurality of through holes 5 are equidistantly provided between the lower handle 3, the upper handle 19 and the protective plate 4, which can effectively reduce the overall material usage of the handle, reduce the weight of the equipment, and make the user feel lighter when using it for a long time.

[0032] Working principle: When in use, place the object in the through slot 12, and then hold the lower handle 3 and the upper handle 19 with your hands. The lower handle 3 and the upper handle 19 are close to each other, and the upper handle 19 drives the punch needle bearing support force arm 17 to rotate, so that the other end of the punch needle bearing support force arm 17 drives the bearing 14 to swing upward, so that the bearing 14 pushes the punch needle 15 to move upward, and the spring 16 is compressed and quickly extends from the inside of the through slot 12 to quickly open a hole in the object. Once you let go, the reverse push of the spring 16 drives the punch needle 15 back into the through slot 12, and drives the punch needle bearing support force arm 17, the bottom film support force forearm 1 and the bottom film support force rear arm to reset. The operation is simple, and the force required for punching is smaller, thereby achieving a fast and efficient punching effect. The contents not described in detail in this manual are all existing technologies known to professional and technical personnel in this field.
