[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] See also Figure 1 、 Figure 2 and Figure 3 A quick clamp in this embodiment includes a fixing plate 1, and two symmetrically arranged support plates 2 are fixedly connected to the upper surface of the fixing plate 1. The top ends of the two support plates 2 are set as inclined surfaces with the right side higher and the left side lower. A workpiece placement block 3 is fixedly connected between the upper right ends of the two support plates 2. A group of fixing grooves 12 are opened on the upper surface of the fixing plate 1. The setting of the fixing grooves 12 makes it convenient for the user to fix it to the external workbench.

[0033] See also Figure 1 、 Figure 2 and Figure 4 The sides of the two support plates 2 that are away from each other are rotatably connected to the swinging plates 4, and a pressure rod 5 is fixedly connected between the near top ends of the two swinging plates 4. A limit plate 6 is provided between each support plate 2 and the swinging plate 4. The top ends of the two limit plates 6 are rotatably connected to the pressure rod 5. The outer surface of the pressure rod 5 is rotatably connected to the pressure roller 19. The outer surface of the pressure roller 19 is provided with an incomplete conical groove 7. Through the setting of the pressure roller 19, when fixing the round bar material, the incomplete conical groove 7 can increase the contact area with the round bar material, thereby improving the fixing stability. When fixing the block material, the surface contact of the pressure roller 19 can achieve the fixation of the block material, thereby improving the overall flexibility and practicality.

[0034] See also Figure 1 、 Figure 2 and Figure 3 The upper surface of the workpiece placement block 3 is provided with an anti-slip groove 15. Through the setting of the anti-slip groove 15, the friction coefficient with the workpiece can be improved, thereby improving the fixing stability. The upper surfaces of the right ends of the two workpiece placement blocks 3 are fixedly connected to two centering plates 8, and the two centering plates 8 are slidably inserted with insertion rods 9. The ends of the two insertion rods 9 close to each other are fixedly connected with wedge blocks 10, and the right ends of the two wedge blocks 10 are set as inclined surfaces. A compression spring 11 is fixedly connected between the two wedge blocks 10 and the centering plates 8 close to them. Through the above setting, when placing materials, the materials can be kept in the center of the workpiece placement block 3 to ensure the straightness of the materials.

[0035] See also Figure 1 、 Figure 2 and Figure 3A connecting block 16 is fixedly connected between the tops of the two swing plates 4, and a handle 17 is fixedly connected to the upper surface of the connecting block 16. By setting the handle 17, the swing plate 4 and the pressure roller 19 can be driven downward to press the workpiece. The outer surface of the handle 17 is knurled. Through the above setting, the friction coefficient of the handle 17 can be improved, thereby improving the comfort of the user. The bottom of the left end of the workpiece placement block 3 contacts the support platform 13. By setting the support platform 13, the support of the workpiece placement block 3 can be achieved. For the purpose of support, a threaded column 14 is fixedly connected to the upper surface of the support platform 13, and the threaded column 14 is plugged into the left end of the workpiece placement block 3. The top of the threaded column 14 is threadedly connected to a nut 18. Through the setting of the nut 18 and the threaded column 14, the connection purpose of the support platform 13 and the workpiece placement block 3 can be achieved. The bottom of the nut 18 contacts the bottom of the workpiece placement block 3. Through the setting of the nut 18 and the threaded column 14, it can also resist one end of the external workpiece to avoid the workpiece from retreating when pressure is applied to the other end.

[0036] A quick clamp in this embodiment, for round rod-type workpieces, this clamp significantly increases the contact area with the workpiece by designing a pressure roller 19 with an incomplete conical groove 7, thereby effectively improving the stability of clamping. For block-shaped workpieces, the circumferential surface of the pressure roller 19 is fully utilized, and its rotation characteristics enable the pressure roller 19 to flexibly adapt to the surfaces of workpieces of different shapes and sizes, thereby improving the stability of clamping. Through the design of the centering plate 8, the insertion rod 9 and the wedge block 10, this clamp can automatically adjust the material to the center position of the workpiece placement block 3 when placing the material, ensuring the straightness of the material. Through the coordinated use of the nut 18 and the threaded column 14, this clamp can also resist one end of the external workpiece, avoiding the workpiece from retreating due to uneven force during processing, thereby improving the safety of the processing process.

[0037] The working principle of the above embodiment is as follows: when it is necessary to clamp a round bar-like workpiece, the workpiece is placed on the workpiece placement block 3 so that it is opposite to the incomplete conical groove 7 of the pressure roller 19. Then, by operating the handle 17, the swing plate 4 and the pressure rod 5 are driven to move downward, thereby making the pressure roller 19 fit tightly against the surface of the round bar. Due to the design of the incomplete conical groove 7, the pressure roller 19 can significantly increase the contact area with the workpiece, thereby ensuring the stability of clamping. For block-shaped workpieces, they are also placed on the workpiece placement block 3, but at this time they are mainly clamped using the circumferential surface of the pressure roller 19. By operating the handle 17, the pressure roller 19 is rotated and fits tightly against the surface of the workpiece. The rotation characteristics of the pressure roller 19 enable it to flexibly adapt to the surfaces of workpieces of different shapes and sizes, further enhancing the versatility and practicality of the fixture. In the process of placing the workpiece, when the material is inserted between the two wedge blocks 10 from the right end, the inclined surface of the wedge block 10 is squeezed to move the two wedge blocks 10 away from each other, thereby compressing the compression spring 11, and the workpiece is clamped by the reaction force of the spring, ensuring that the material is in the center of the workpiece placement block 3. In addition, the coordinated use of the nut 18 and the threaded column 14 also improves the safety of the processing process. The nut 18 is in close contact with one end of the workpiece, achieving the effect of resisting one end of the workpiece.
