[0002] Hardware refers to tools made from metals such as gold, silver, copper, iron, and tin through processing and casting. They are used to fix things, process things, and decorate. Hardware includes metal products such as hardware tools, hardware parts, daily hardware, building hardware, and security products. When processing and producing hardware, it is necessary to weld and assemble the hardware.
[0003] Authorized publication number CN220330423U discloses a welding fixture for processing hardware parts, including a base and baffles. Baffles are movably mounted on the upper surface and sides of the base. Fixing plates are fixedly mounted on the side surfaces and rear of the base. A threaded sleeve is fixedly mounted on the upper surface and rear of the base. A threaded rod is movably mounted inside the threaded sleeve. A support block is movably mounted at the front end of the threaded rod. Clamping plates are provided on both sides of the support block, and positioning elements are provided on both sides above the support block. This welding fixture for processing hardware parts, when clamping and fixing hardware parts at different angles, allows for adjustment of the angles of the clamping plates and baffles through the interaction of the baffles, support blocks, positioning elements, and clamping plates. This enhances the adaptability of the welding fixture.
[0004] Based on the above research and existing technology findings, when adjusting the angle of hardware components, after adjusting the angle of the clamping plate, it is also necessary to adjust the angle of the baffle and use external equipment to hold the baffle in place before the hardware component can be clamped and fixed between the clamping plate and the baffle. The angle adjustment operation is relatively cumbersome, the angle adjustment range is limited, and it is impossible to adjust it to a horizontal position, so the usage effect needs to be improved. Based on this, this utility model provides a hardware welding and fixing clamp. Utility Model Content

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0021] According to the appendix Figure 1 , 3 As shown in Figure 4: This utility model provides a hardware welding fixing fixture, including a base 1, with adjustable clamping parts 2 on both sides of the top of the base 1. The clamping parts 2 include a drive box 3 fixedly installed on the top of the base 1. A support rod 4 is rotatably connected to the top of the drive box 3. The top of the drive box 3 is rotatably connected to the support rod 4 through a bearing 10. The lower end of the support rod 4 is inserted into the drive box 3. The drive box 3 is provided with a drive part 5 for driving the support rod 4 to rotate. The drive part 5 includes a worm gear 11 rotatably connected to an inner side wall of the drive box 3. The other end of the worm gear 11 extends out of the drive box 3 and is equipped with a handle 12. The bottom of the support rod 4 is equipped with a worm wheel 13 that meshes with the worm gear 11. The top of the base 1 is equipped with angle markings 15 placed around the support rod 4 and outside the drive box 3. Specifically, by gripping the handle 12 and rotating it, the worm gear 11 is rotated. Under the meshing connection between the worm gear 11 and the worm wheel 13, the worm wheel 13 is rotated, which in turn rotates the support rod 4. By observing the direction of the angle markings 15 pointed to by the C-shaped clamp 6, the angle direction for adjustment can be accurately determined.
[0022] As per the instruction manual Figure 1-3As shown: The top of the support rod 4 is provided with a C-shaped clamp 6, and the bottom of the C-shaped clamp 6 is slidably connected to a clamping plate 7. The bottom of the C-shaped clamp 6 is symmetrically provided with limiting grooves 14 that match the bottom of the clamping plate 7, which serve to limit the clamping plate 7. One side wall of the clamping plate 7 is rotatably connected to a screw 8 that is threadedly connected to the side wall of the C-shaped clamp 6. The other end of the screw 8 is provided with a handwheel 9 placed on the outside of the C-shaped clamp 6. Specifically, by holding the handwheel 9 and rotating it, the screw 8 is rotated and moved back and forth. Under the limitation of the limiting grooves 14, the clamping plate 7 can be moved back and forth, so that the hardware to be welded can be easily clamped and fixed between the C-shaped clamp 6 and the clamping plate 7.
[0023] The principle of this utility model
[0024] In use, with the worm gear 11 and worm wheel 13 meshing, the support rod 4 is rotated by gripping the handle 12. The angle mark 15 is observed to determine the angle direction of the C-shaped clamp 6. Then, the hardware to be welded is placed in the C-shaped clamp 6 and positioned. By gripping the handwheel 9, the clamping plate 7 is moved back and forth to clamp and fix the hardware to be welded between the C-shaped clamp 6 and the clamping plate 7. The C-shaped clamp 6 can be flexibly adjusted to a suitable horizontal or inclined position according to the hardware welding needs, with a wider adjustment range, so as to weld hardware fixed at multiple angles. Moreover, no external equipment is needed to resist when clamping and fixing the hardware to be welded. The angle adjustment operation is relatively simple and the use effect is greatly improved.
