DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Example: Figure 1-2As shown, a fixture that is easy to replace includes a main body 1, a fixed plate 2, and a slider 21. A water tank 11 is installed at the front end of the main body 1. A water inlet 10 and a connecting pipe 9 are provided at the upper end of the water tank 11. Water is filled into the water tank 11 through the water inlet 10. A water outlet 12 is provided at the front end of the water tank 11. A valve 13 is fixedly installed at the upper end of the water outlet 12. The valve 13 is opened so that the water inside the water tank 11 can be discharged from the water outlet 12. A hose 8 is connected to the upper end of the connecting pipe 9. An exhaust fan 6 is installed at the upper end of the fixed plate 2. A support plate 7 is installed at the front end of the fixed plate 2. The exhaust fan 6 is supported by the support plate 7. A hose 8 is provided at the rear end of the exhaust fan 6. The exhaust fan 6 is connected to the connecting pipe 9 through the hose 8. When dust particles are generated during mechanical processing, the generated dust particles are absorbed by the exhaust fan 6, and the absorbed dust particles are transported to the connecting pipe 9 through the hose 8. The pipe 9 transports the dust particles to the inside of the water tank 11, and water is filled into the water tank 11 through the water inlet 10 to mix with the dust particles. When the mixed water needs to be cleaned, the valve 13 is opened to discharge the mixed water through the water outlet, so as to collect and clean the dust particles generated by mechanical processing, thereby preventing the dust particles from affecting the surroundings. A slide rail 16 is arranged inside the fixed plate 2, and a bidirectional screw 17 is arranged inside the slide rail 16. A servo motor 4 is installed at the left end of the fixed plate 2, and the output shaft of the servo motor 4 is fixedly connected to the bidirectional screw 17, and the bidirectional screw 17 is driven to rotate by the servo motor 4. The outer side of the bidirectional screw 17 is threadedly connected to two sliders 21, and a connecting block 3 is fixedly installed on the upper end of the slider 21. The rotation of the bidirectional screw 17 drives the two sliders 21 to move in the opposite direction, and the slider 21 drives the connecting block 3 to move, and the connecting block 3 drives the clamp 5 to move.

[0026] like Figure 3-4 As shown, two electric telescopic rods 18 are installed inside the main body 1, and a telescopic box 14 is fixedly installed on the upper end of the electric telescopic rod 18. Two first protrusions 15 are installed on the left and right ends of the telescopic box 14. Four first convex grooves 19 are arranged inside the main body 1, and the first protrusions 15 are connected with the first convex grooves 19, so that the electric telescopic rod 18 is more stable when adjusting the height of the telescopic box 14. A fixed plate 2 is installed on the upper end of the telescopic box 14 to drive the fixed plate 2 to move up and down.

[0027] like Figure 5As shown, a connecting block 3 is installed on the upper end of the slider 21, and a second convex groove 23 is provided inside the connecting block 3. The second convex groove 23 is plugged and connected to the second protrusion 20. A clamp 5 is installed on the upper end of the second protrusion 20. The internal thread of the connecting block 3 is connected to a hand screw 22. The internal screw hole of the second protrusion 20 matches the size of the hand screw 22. The hand screw 22 is inserted into the connecting block 3 and the second protrusion 20 to fix them. When the clamp 5 needs to be replaced, it only needs to twist the hand screw 22 out of the connecting block 3 and the second protrusion 20, and then slide the second protrusion 20 out of the second convex groove 23 to replace the clamp 5. Therefore, it is more convenient. A rubber pad 24 is installed at one end of the clamp 5 to make it more flexible when fixed.

[0028] Working principle: The servo motor 4 drives the bidirectional screw 17 to rotate, and the outer side of the bidirectional screw 17 is connected to two sliders 21 with threads, and the upper end of the slider 21 is fixedly installed with a connecting block 3. The rotation of the bidirectional screw 17 drives the two sliders 21 to move in the opposite direction, and the slider 21 drives the connecting block 3 to move, and the connecting block 3 drives the clamp 5 to move, thereby completing the fixation. When dust particles are generated during mechanical processing, the dust particles generated are absorbed by the exhaust fan 6, and the absorbed dust particles are transported to the connecting pipe 9 through the hose 8, and the dust particles are transported through the connecting pipe 9 Go to the inside of the water tank 11, fill the water into the water tank 11 through the water inlet 10 to mix with the dust particles. When the mixed water needs to be cleaned, open the valve 13 to discharge the mixed water through the water outlet, so as to collect and clean the dust particles generated by the mechanical processing, thereby preventing the dust particles from affecting the surroundings. When the clamp 5 needs to be replaced, it is only necessary to twist out the hand screw 22 from the inside of the connecting block 3 and the second protrusion 20, and then slide the second protrusion 20 out of the second protrusion groove 23 to replace the clamp 5, so it is more convenient.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
