Description

Technical Field

[0001] This utility model relates to the field of hand pliers technology, specifically to a type of hand pliers. Background Technology

[0002] Existing hand pliers are too small and have many limitations. They cannot be used with various button molds, have a short stroke, and insufficient punching force, so they cannot fasten buttons on large bags and other products. They are also very difficult for women to use and cannot be fixed to a table. As a result, many factories and traders cannot use them, and only home users can use them. Utility Model Content

[0003] The purpose of this invention is to provide a hand clamp to solve at least one of the aforementioned problems in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hand clamp includes a clamp body, a handle, and a retainer. The retainer includes a fixing frame and a screw. The fixing frame is disposed at the lower end of the clamp body, and the screw is threadedly connected to the lower end of the fixing frame. The lower end of the screw is the operating end, and the upper end is the abutment end.

[0006] In this technical solution, the clamp can fix the entire clamp body to the table, which can prevent the clamp body from shaking during use and affecting the pressure effect. After being fixed by the clamp, the handle can be pressed down without adjusting other directions, which can free up the hands and make the process of attaching buttons more convenient and easy. A large clamping or shearing force can be generated with a small amount of hand pressure, which is more labor-saving and convenient.

[0007] Furthermore, to facilitate operation and ensure a secure fixation effect, a support plate is threaded to the upper end of the screw, and a screw head is threaded to the lower end of the screw.

[0008] Furthermore, to improve the stability of the fixation, a pad is fixed on the support plate.

[0009] Furthermore, in order to provide a specific padding layer, the padding layer is a sponge pad.

[0010] Furthermore, to facilitate the fixed installation of the U-shaped frame, the fixing frame is a U-shaped frame, and the upper end of the U-shaped frame is fixedly connected to the lower end of the clamp body by screws.

[0011] Furthermore, the clamp body includes a U-shaped inner cavity with a length of 9cm. Existing U-shaped inner cavities are 6cm long; this technical solution extends the cavity length to 9cm, making it more convenient for use with large bags and meeting the size requirements of large bags.

[0012] Furthermore, the handle is 22.5cm long and 20.5cm wide. Existing handles are 16.5cm long and 16.5mm wide, making them too small and requiring more effort to operate. This technical solution lengthens and widens the handle, making operation easier and more convenient.

[0013] Furthermore, it also includes a connecting piece, a pin, and a spring. The handle is provided with a first connecting position and a second connecting position. The upper end of the connecting piece is rotatably connected to the first connecting position, and the lower end of the connecting piece is rotatably connected to the upper end of the clamp body. The upper end of the pin is rotatably connected to the second connecting position. The pin is slidably engaged with the connecting hole on the clamp body. One end of the pin that extends into the U-shaped inner cavity is provided with an M8 internal thread. The lower end of the clamp body is provided with a through hole with an inner diameter of 10mm at the position corresponding to the pin.

[0014] Because the pin has an M8 internal thread at one end that extends into the U-shaped cavity, the upper mold can be replaced and installed. The upper mold has an M8 internal thread and can be screwed on directly. Because the lower end of the clamp body has a through hole with an inner diameter of 10mm at the position corresponding to the pin, the lower mold can be replaced and installed. The lower mold shank size is 10mm. Simply insert the lower mold shank into the through hole and then tighten the shank with the set screw to fix the lower mold in place.

[0015] With its M8 internal thread and 10mm through hole, it can be equipped with a variety of interchangeable molds, such as those for snap fasteners, five-prong fasteners, eyelets, and rivets, meeting the needs of button processing in different situations and reducing the number of tools and the complexity of operation.

[0016] Furthermore, the clamp body is made of aluminum alloy ADC12. The clamp body is coated with a baked enamel finish after aluminum alloy casting, which increases the clamp body's strength and wear resistance.

[0017] Furthermore, the connecting plate, handle, and pin are all detachably mounted on the clamp body. The connecting plate, handle, and pin can be replaced as needed to accommodate workpieces of different shapes and sizes, achieving a wider range of clamping functions.

[0018] The beneficial effects of this utility model are as follows: In this technical solution, the clamp can fix the clamp body as a whole on the table, which can prevent the clamp body from shaking during use and affecting the pressure effect. After being fixed by the clamp, the handle can be pressed down without adjusting other directions, which can free up the hands and make it more convenient and easy to fasten buttons. A large clamping or shearing force can be generated with a small amount of hand pressure, which is more labor-saving and convenient. Attached Figure Description
