[0029] The clamping device 3 includes a positioning frame 31, a guide groove 32 is opened inside the positioning frame 31, a first connecting rod 33 is fixedly connected to the inner surface of the positioning frame 31, a second spring column 34 is fixedly connected to the inner surface of the positioning frame 31, the outer surface of the first connecting rod 33 is movably connected to the second connecting rod 35, and the outer surface of the second connecting rod 35 is fixedly connected to a clamping block 36.

[0030] Furthermore, the fixing frame 21 is fixedly connected to the outer surface of the shell 11, the alignment groove 22 is opened through the inner and outer ends of the fixing frame 21, and the fixing member 23 is movably connected to the outer surface of the alignment groove 22. Through the setting of the alignment groove 22, the fixing member 23 can be effectively movably connected to the outer surface of the fixing frame 21, so that the fixing member 23 can be easily disassembled and installed.

[0031] Furthermore, the fixing columns 24 are fixedly connected in four groups to the four corners of the outer surface of the fixing member 23, the placement member 25 is fixedly connected to the side surface of the fixing member 23 away from the fixing frame 21, and the fan 26 is fixedly connected to the center of the placement member 25. Through the setting of the fan 26, the air between the inner and outer ends of the fixing frame 21 can be effectively exchanged, thereby achieving a cooling effect on the shell 11.

[0035] Furthermore, one end of the first spring column 212 is fixedly connected to the inner wall of the fixing member 23, and the other end of the first spring column 212 is fixedly connected to the inward side surface of the limit block 210. The push rod 211 penetrates and is connected to the inside of the fixing frame 21. Through the setting of the push rod 211, after the limit block 210 is squeezed outward, the first spring column 212 can reset the limit block 210 in time.

[0036] Furthermore, the clamping block 36 is fixedly connected to the surface of one end of the second connecting rod 35 away from the first connecting rod 33, and both ends of the second spring column 34 are fixedly connected between the positioning frame 31 and the clamping block 36. The end of the first connecting rod 33 away from the positioning frame 31 is movably connected to the inside of the second connecting rod 35. Through the setting of the second connecting rod 35, when the second spring column 34 is compressed, it can be ensured that the second spring column 34 will not be deformed, thereby causing damage to the device. The outer surface of the guide groove 32 can be inserted with a filter net, which can filter out some large particles of dust and impurities when the environment is relatively harsh.

[0037] Working principle: When in use, align the fixing member 23 with the outer surface of the alignment groove 22, align the fixing column 24 with the fixing block 29, and then press the fixing member 23 inwardly toward one side of the alignment groove 22, and the side of the limit block 210 with the bevel will slide into the position between the fixing block 29 and the sliding block 28. Since the fixing block 29 is fixed, the limit block 210 will be inserted between the fixing block 29 and the sliding block 28 under the action of the first spring column 212, so that the fixing member 23 is limited and fixed on the outer surface of the fixing frame 21. When you want to disassemble the fixing member 23 When the fixing piece 23 is pressed toward one side of the sliding block 28, the angled side of the limit block 210 will move to the outer surface of the support rod 27 between the sliding block 28 and the fixing frame 21, and the fixing piece 23 is pulled outward. At this time, the limit block 210 will drive the sliding block 28 to slide to the inner side of the fixed block 29. Since the bottom of the sliding block 28 has an angle, when it is pulled strongly, the limit block 210 will move on the surface of the sliding block 28, so that the limit block 210 slides to the upper surface of the fixed block 29, thereby releasing the limit of the fixed block 29 on the fixed column 24.

[0038] The filter screen is obliquely inserted into the interior of the positioning frame 31 through the guide groove 32. Under the action of the clamping block 36, the second spring column 34 will push the clamping block 36 to clamp on the outer surface of the filter screen, thereby achieving the limiting fixation of the filter screen.
