[0002] Leather refers to materials made from animal fur, usually leather. Leather is a high-grade, durable, textured natural material with good air permeability, moisture absorption and wear resistance. It is widely used in the production of clothing, shoes and hats, household items, car seats, luggage and handbags and other products. In the process of leather processing, leather bonding clamps are one of the indispensable tools. Leather bonding clamps are usually made of metal or plastic, with a certain clamping force and stability, which can ensure that the leather to be bonded will not move or dislocate during the bonding process.

[0028] 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a new type of leather bonding clamp, including a fixed block 1, the left and right sides of the outer wall of the fixed block 1 are provided with a card slot 8, the inner side of the card slot 8 is engaged with a card buckle 9, the end of the card buckle 9 is fixedly connected with a plywood 10, the left and right sides of the middle part of the outer wall of the fixed block 1 are provided with a mounting groove 7, the inner side of the mounting groove 7 is provided with a hollow column 16, the inner wall of the hollow column 16 is fixedly connected with a first spring 14, the end of the first spring 14 is fixedly connected with a sliding column 12, the top of the fixed block 1 is provided with a slot 3, the inner side of the slot 3 is rotatably connected with a rotating shaft 4, the middle part of the rotating shaft 4 is fixedly connected with a right angle plate 6, the outer side of the fixed block 1 is provided with a clamping mechanism 2; the top of the right angle plate 6 is fixedly connected with a pull ring 5; the upper and lower sides of the sliding column 12 are fixedly connected with a slider 13, the upper and lower sides of the inner wall of the hollow column 16 are provided with a slide groove 15, and the slider 13 is slidably connected with the corresponding slide groove 15 respectively;

[0030] Specifically, the core parts of this device are the buckle 9 and the slot 8; during the operation, the plywood 10 is first taken out, and then the buckle 9 is aligned with the slot 8 and inserted; through the precise engagement of the buckle 9 and the slot 8, the plywood 10 can be firmly installed on the device; this design makes the installation process of the plywood 10 simple and quick, and greatly improves the work efficiency; in addition, this device also adopts components such as the slide column 12, the first spring 14 and the slider 13, which together constitute a precise limit control system; in the process of the plywood 10 squeezing the slide column 12, the first spring 14 will drive the slide column 12 to retract, thereby driving The slider 13 slides in the slide groove 15; this design not only achieves stable fixation of the plywood 10, but also ensures the safety of the equipment during operation; in order to facilitate the replacement of the plywood 10, the designer also cleverly added a pull ring 5, a right-angle plate 6 and a rotating shaft 4; when the plywood 10 needs to be replaced, it is only necessary to pull the pull ring 5, turn the right-angle plate 6, and rotate the rotating shaft 4; at this time, the raised end of the right-angle plate 6 can resist the plywood 10 and lift it out; at the same time, the first spring 14 will extend, increasing the disassembly speed of the plywood 10; this design makes the replacement process of the plywood 10 easy and convenient, greatly reducing the maintenance cost.

[0031] Reference Figure 1 The clamping mechanism 2 includes an F clamp 201, a rack 205 is provided on the inner side of the F clamp 201, a movable clamp 206 is installed at the end of the rack 205, a handle 204 is installed on the right side of the F clamp 201, a second spring 203 is fixedly connected to the inner side of the handle 204, and a reset structure 202 is installed on the right side of the outer wall of the F clamp 201; the F clamp 201 and the movable clamp 206 are symmetrically designed;

[0032] Specifically, firstly, by clamping the leather, it can be ensured that the leather remains stable during the processing; in this process, the core component is the F clamp 201, which is responsible for fixing the leather; in order to achieve precise clamping of the leather, a unique driving system is designed; the system consists of a pressing handle 204 and a rack 205; during operation, when the pressing handle 204 applies downward pressure, the rack 205 will be driven to move; the movement of the rack 205 drives the relative movement of the F clamp 201 and the movable clamp 206; in this way, the clamping surface can be close to the leather, thereby achieving efficient fixation of the leather; after completing the clamping operation, release the handle 204, at which time the second spring 203 rebounds quickly to provide a strong clamping force for the leather.

[0033] Reference Figure 2 The outer wall of the plywood 10 is installed with a rubber pad 11; the hollow column 16 and the installation groove 7 are designed to fit together; the plywood 10 is made of wood;

[0034] Specifically, the rubber pad 11 can prevent the leather from being squeezed and damaged, and the fitting design can make the installation of the hollow column 16 more fixed.

[0035] Working principle: Take the matching plywood 10 and align the buckle 9 with the slot 8 for insertion. The plywood 10 is installed and fixed by the engagement of the buckle 9 with the slot 8. When the plywood 10 squeezes the slide post 12, the first spring 14 drives the slide post 12 to retract. When the slide post 12 moves, the slider 13 is driven to slide in the slot 15, which is used for the position limiting work when the slide post 12 moves. At the same time, the movement trajectory of the slide post 12 is planned. When the plywood 10 needs to be replaced, the right-angle plate 6 is pulled by the pull ring 5 and the shaft 4 is rotated at the same time. The raised end of the right-angle plate 6 is pressed against the plywood 10 to replace the plywood. The board 10 is tilted out, and the first spring 14 is stretched at the same time, which increases the disassembly speed of the plywood 10. The clamping surface can be replaced and adjusted in time to meet the needs of use. When clamping the leather material, pressing the handle 204 drives the rack 205 to move at the same time, so that the F clamp 201 and the movable clamp 206 move relative to each other, so that the clamping surface fits the material and clamps the material. When the handle 204 is released, the second spring 203 rebounds quickly to provide efficient clamping force. The F clamp 201 is a prior art and is not described in detail in this application, which brings convenience to use.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
