[0022] The inventors of the present application found that during the process of shoveling teeth on the heat sink, the sizes of different types of heat sinks will vary, and corresponding shovels with different widths are required. Limited by the structural settings of the shovels, in order to achieve precise positioning and fixing of the shovels, each shovel is correspondingly provided with a fixture adapted to it. When replacing shovels with different widths, it is necessary to frequently disassemble and reinstall the fixture, which is cumbersome and time-consuming, seriously affecting the production efficiency. Therefore, the present application discloses an adjustable single-shovel clamping device, mainly adopting the following solutions: Embodiment 1

Then, by rotating the adjustment screw 31, the adjustment screw 31 abuts against the tail end of the shovel, so as to achieve precise positioning of the position of the shovel in the clamping groove and ensure the structural stability of the shovel after clamping. In addition, by rotating the adjustment screw 31, the shovel can also be pushed to slide in the clamping groove, realizing precise adjustment of the front and rear positions of the shovel, so as to adapt to shovels with different lengths or processing requirements, and improving the flexibility and application range of the clamping device.

[0025] Reference Figure 1 and Figure 2 The tool holder 1 can be made of aluminum alloy or stainless steel, with high strength and wear resistance. Limiting blocks 121 are fixedly arranged on both side walls of the adjusting block 12. Limiting grooves 111 for the limiting blocks 121 to slide are formed on both side walls of the two sides of the adjusting groove 11. The limiting blocks 121 on both sides of the adjusting block 12 are integrally formed with the adjusting block 12. The shape of the limiting groove 111 is adapted to that of the limiting block 121 to ensure the stable sliding of the adjusting block 12 in the adjusting groove 11.

[0026] Reference Figure 1 and Figure 2 Specifically, the limiting structure includes limiting bolts 22. A plurality of limiting bolts 22 are provided. A plurality of through holes are formed in the adjusting seat 2. The limiting bolts 22 correspond to the through holes one by one, and the limiting bolts 22 are inserted into the corresponding through holes.

By tightening the limiting bolts 22, the adjusting seat 2 is pressed against the end face of the tool holder 1 to limit the adjusting seat 2, improving the reliability of fixing the adjusting seat 2 on the tool holder 1. The limiting bolts 22 can be made of high-strength alloy steel material and the surface is hardened to improve durability.

[0027] Reference Figure 1 and Figure 3 Furthermore, anti-slip patterns 4 are arranged on the end faces of the adjusting seat 2 and the tool holder 1 close to each other. The anti-slip patterns 4 can be designed in a sawtooth shape or a wavy shape to increase the friction force and prevent the adjusting seat 2 from loosening. In addition, the depth of the anti-slip patterns 4 can be adjusted according to actual needs, for example, set between 0.5 mm and 2 mm to achieve the best anti-slip effect.

[0028] Reference Figure 2 and Figure 3 Guide bars 13 are arranged on the end face of the tool holder 1 close to the adjusting seat 2. Two guide bars 13 are provided and are respectively arranged on both sides of the adjusting groove 11. The guide bars 13 are integrally formed with the tool holder 1. The length direction of the guide bars 13 is parallel to the sliding direction of the adjusting block 12. Two guide grooves 23 are formed at one end of the adjusting seat 2 close to the tool holder 1. The guide grooves 23 correspond to the guide bars 13 one by one, and the guide grooves 23 are adapted to the guide bars 13. The guide bars 13 are arranged in the guide grooves 23. The surface of the guide bars 13 is polished to reduce the frictional resistance. The cooperation of the guide bars 13 and the guide grooves 23 can effectively improve the stability of the adjusting seat 2 during the sliding process and avoid the phenomenon of deviation or jamming of the adjusting seat 2. Combined with the limiting structure, this design makes the position adjustment of the adjusting seat 2 more accurate.

[0029] Reference Figure 3, a receiving groove 24 is formed in the side wall of the guiding groove 23 away from the tool holder 1. A top block 25 is slidably arranged in the receiving groove 24 along the direction close to or away from the guiding strip 13. A first elastic member is arranged in the receiving groove 24 for driving the top block 25 to slide towards the guiding strip 13. Specifically, the first elastic member includes an elastic steel sheet 26 which is arranged in a "U" shape. The elastic steel sheet 26 is installed in the receiving groove 24 and abuts against the top block 25 and the side wall of the receiving groove 24 away from the guiding strip 13 respectively, so that the top block 25 always has a tendency to slide towards the guiding strip 13, thereby applying a certain elastic supporting force to the adjusting seat 2, increasing the structural stability of the adjusting seat 2 on the tool holder 1, and facilitating the installation and positioning of the cutting blade. In addition, the first elastic member can also be a spring or elastic rubber.

[0030] Refer to Figure 3 , a plurality of rollers 251 are rotatably arranged on the end face of the top block 25 close to the guiding strip 13. The rollers 251 are in rolling connection with the guiding strip 13. The rollers 251 can be made of stainless steel or ceramic materials, which have high hardness and wear resistance, can significantly reduce the frictional resistance during the sliding process of the adjusting seat 2, make the position adjustment of the adjusting seat 2 smoother, and at the same time extend the service life of the guiding strip 13 and the guiding groove 23.

[0031] Refer to Figure 4 , specifically, the locking assembly includes locking blocks 5 and locking members. There are a plurality of locking blocks 5, which can be made of high-strength alloy steel material and the surface is hardened to improve durability. A pressing portion 51 for abutting against the cutting blade is arranged on the locking block 5, and the pressing portion 51 is integrally formed with the locking block 5. The locking members include locking bolts 52. There are a plurality of locking bolts 52, which correspond to the locking blocks 5 one by one. Installation holes 53 are formed in the locking blocks 5, and the locking bolts 52 are inserted into the installation holes 53 of the corresponding locking blocks 5, and the locking bolts 52 are in threaded cooperation with the corresponding adjusting seats 2. The locking bolts 52 can be made of high-strength alloy steel material and the surface is galvanized to improve the anti-corrosion performance. The locking bolts 52 fix the corresponding locking blocks 5 on the adjusting seats 2, and the pressing portions 51 on the locking blocks 5 abut against the surface of the cutting blade, thereby firmly fixing the cutting blade in the clamping groove, effectively preventing the cutting blade from loosening or shifting during the processing, and improving the reliability of the cutting blade clamping.

[0032] Refer to Figure 4, a positioning sleeve 54 is provided on each locking block 5. The positioning sleeve 54 is cylindrical and integrally formed with the locking block 5. The mounting hole 53 communicates with the positioning sleeve 54. The locking bolt 52 is inserted into the positioning sleeve 54 of the corresponding locking block 5, and the locking bolt 52 is adapted to the positioning sleeve 54. A plurality of positioning grooves 27 adapted to the positioning sleeve 54 are formed on the adjusting seat 2. The positioning grooves 27 correspond to the locking blocks 5 one by one, and the positioning sleeves 54 on each locking block 5 are inserted into the corresponding positioning grooves 27. The setting of the positioning sleeve 54 plays a guiding role in the movement of the locking block 5, enabling the locking block 5 to slide along the direction close to or away from the adjusting seat 2 while being able to rotate around the positioning sleeve 54 as the rotation axis. At the same time, it ensures that the locking block 5 will not shift during the process of locking and fixing the cutting blade, improving the reliability of the locking assembly. In addition, the matching design of the positioning groove 27 and the positioning sleeve 54 simplifies the assembly process of the locking assembly and improves the assembly efficiency.

[0033] Refer to Figure 4 , a second elastic member for driving the positioning sleeve 54 to slide away from the positioning groove 27 is provided in the positioning groove 27. The second elastic member uses a compression spring 28. The compression spring 28 is sleeved on the locking bolt 52, and one end of the compression spring 28 abuts against the lower side wall of the positioning groove 27, and the other end abuts against the positioning sleeve 54. The setting of the second elastic member can provide a certain elastic supporting force for the positioning sleeve 54. When the locking bolt 52 is loosened, the positioning sleeve 54 can move away from the adjusting seat 2 under the elastic force of the second elastic member, providing sufficient space for the installation of the cutting blade and improving the convenience of cutting blade installation.

[0034] Refer to Figure 4 , a plurality of limit card slots 29 are formed on the adjusting seat 2. The limit card slots 29 correspond to the positioning grooves 27 one by one, and the limit card slots 29 communicate with the card slots 21 and the corresponding positioning grooves 27 respectively. The limit card slots 29 are adapted to the locking blocks 5 and are used for the corresponding locking blocks 5 to be inserted. The setting of the limit card slots 29 enables the locking blocks 5 to be accurately inserted, effectively preventing the locking blocks 5 from shifting during the fixing process, enhancing the reliability of the locking assembly, avoiding deflection or loosening of the locking blocks 5 caused by external forces, and thus ensuring the stability of the cutting blade during the processing. At the same time, the communication design of the limit card slots 29 with the positioning grooves 27 and the card slots 21 can also play a guiding role in the installation of the locking blocks 5, simplify the operation process, and improve the assembly efficiency.

[0035] The implementation principle of Embodiment 1 of this application, an adjustable single shovel blade clamping device, is as follows: The cooperation of the sliding adjustment block 12 and the limit block 121 with the limit groove 111 ensures the stable sliding and positioning of the adjustment seat 2 on the tool holder 1, adapts to the clamping requirements of shovel blades with different widths, and realizes precise control of the installation position of the shovel blade. The setting of the limit structure can firmly fix the adjustment seat 2 on the tool holder 1, improving the reliability of the adjustment seat 2 fixed on the tool holder 1. The combination of the clamping groove 21 and the locking component effectively ensures the stability of the shovel blade during clamping, avoiding loosening or deviation during the processing, thereby improving the installation efficiency and positioning accuracy of the shovel blade. Embodiment 2

[0036] Refer to Figure 5 , the difference from Embodiment 1 is that: a chute 33 is provided on the mounting bracket 3 along the sliding direction of the adjustment block 12, a slider 34 is slidably arranged in the chute 33, an adjustment screw 31 is passed through the slider 34 and is in threaded cooperation with the slider 34, and a push rod 35 is rotatably sleeved on the adjustment screw 31. The push rod 35 is located between the two adjustment seats 2. When the adjustment seat 2 slides, the slider 34 slides together with the adjustment seat 2. When the shovel blade is installed, by rotating the adjustment screw 31, the push rod 35 abuts against the tail end of the shovel blade, and precise positioning of the shovel blade in the clamping groove can be achieved, improving the convenience of use.
