[0015] 1. Through the cooperation of components such as the second clamping plate, when the dust-proof net needs to be spliced according to the length during use, the two dust-proof nets to be spliced can be placed together and placed inside the pulling groove. Subsequently, the first clamping plate and the second clamping plate are fixed to the ports at the edges of the dust-proof net through the bolt assembly, so as to realize the automatic splicing of multiple sections of the dust-proof net, facilitate the splicing and use of the dust-proof net according to requirements, and thus improve the overall practicality of the device;

[0016] 2. By setting the cooperation of parts such as the first clamping block, when a part of the dust-proof net is cracked during use, a first clamping plate and a second clamping plate can be assembled and fixed on one side of the cracked part of the dust-proof net. Subsequently, according to the length of the crack of the dust-proof net, a first clamping block that is longer than the cracked position by a certain distance is assembled through a bolt assembly. Then, one end of a set of first clamping blocks can be fixedly connected to a rectangular connecting block through screws. After a set of first clamping blocks and a second clamping plate are assembled, a first clamping plate and a second clamping plate can be assembled and fixed on the other side of the cracked part of the dust-proof net, and the other second clamping plate can be fixed to it through a rectangular connecting block connected by inner sliding. Subsequently, another set of first clamping blocks can be installed below the already installed set of first clamping blocks according to the height of the cracked part of the dust-proof net, and the other set of first clamping blocks can be respectively fixed to the two second clamping plates. After the two sets of first clamping blocks are installed, a new section of the dust-proof net can be hung on the two sets of first clamping blocks through the net clamping block, so that a new section of the dust-proof net can cover the cracked part. In this way, the device can repair the cracked part of the dust-proof net according to the need.

Before assembling the first clamping plate and the second clamping plate, one end of the broken dust-proof net can be trimmed neatly with scissors or other tools, and then the adjusting bolt is rotated. Since the end of the adjusting bolt is rotatably connected to the second auxiliary slider, the second auxiliary slider can be pushed to drive the rotating roller to move horizontally, so that the rotating roller is adjusted to the middle position of the pulling groove. Then, one end of the corrected dust-proof net can be snapped into the clamping groove, and then the rocker is rotated, so that the worm gear drives the rotating roller to rotate through the connecting shaft rod to wind the dust-proof net several times, so as to ensure the stability of subsequent splicing. Then, the other group of first clamping plates and second clamping plates are assembled to the other end of the break of the dust-proof net by the above method, and then a new section of dust-proof net is patched between the two groups of first clamping plates and second clamping plates, thus forming the function of repairing the broken dust-proof net, and further improving the overall practicality of the device;

[0019] 5. By setting the cooperation of parts such as the slot, when the two groups of first clamping plates and second clamping plates are symmetrically assembled, only one side of one second clamping plate is provided with a lead screw. When the tension of the repaired dust-proof net needs to be adjusted, the plug can be first pulled upward to pull the plug out of the slot, and then the female buckle can be pulled outward of the second clamping plate so that the female buckle is snapped into the male buckle. Then the plug is released. When the pin inside the plug is aligned with the slot, the plug is reset and inserted into the slot under the action of the connecting spring, so as to fix the winding roller and the rotating roller. When the slot is misaligned with the pin inside the plug, during the process of rotating the rocker, the slot can be adjusted to be aligned with the pin inside the plug, so that the plug is reset under the action of the connecting spring. When the rotating roller rotates, the connecting rope can be wound through the winding roller, so as to pull a group of first clamping blocks to move through the female buckle, so as to tighten the repaired dust-proof net, improving the overall protection performance and use effect of the dust-proof net.

The winding device can be composed of a winding roller, a support frame and a servo motor. Thus, the dust-proof net 2 can be wound and released.

When a part of the dust-proof net 2 is cracked during use, a first clamping plate 1 and a second clamping plate 39 can be assembled and fixed on one side of the cracked part of the dust-proof net 2.

[0036] The rotating screw rod 4 can drive the rectangular connecting block 13 to drive the installed group of first clamping blocks 3 to move downward, so as to adjust the position according to the dust-proof net 2 at the cracked position, thereby improving the overall practicality of the device;

[0039] When the dust-proof net 2 breaks during use after being laid, and it needs to be repaired and connected again, the two groups of first clamping plates 1 and second clamping plates 39 can be respectively pressed on the break of the dust-proof net 2. Before assembling the first clamping plate 1 and the second clamping plate 39, one end of the broken dust-proof net 2 can be trimmed neatly with scissors or other tools, and then the adjusting bolt 33 is rotated.

[0040] When the two groups of first clamping plates 1 and second clamping plates 39 are symmetrically assembled, only one side of one second clamping plate 39 is provided with a lead screw 4. When the tension of the repaired dust-proof net 2 needs to be adjusted, the plug 28 can be first pulled upward to pull the plug 28 out of the slot 27. Then, the female buckle 22 can be pulled outward to the second clamping plate 39, so that the female buckle 22 is buckled into the male buckle 17. Then, the plug 28 is released. When the insertion pin inside the plug 28 is aligned with the slot 27, the plug 28 is reset and inserted into the slot 27 under the action of the connecting spring, so as to fix the roller 26 and the roller 25. When the slot 27 is misaligned with the insertion pin inside the plug 28, during the rotation of the rocker 37, the slot 27 and the insertion pin inside the plug 28 can be adjusted to be aligned, so that the plug 28 is reset under the action of the connecting spring. When the roller 25 rotates, the connecting rope 30 can be wound through the roller 26, so as to pull a group of first clamping blocks 3 to move through the female buckle 22, so as to tighten the repaired dust-proof net 2, improving the overall protection performance and use effect of the dust-proof net 2;

[0041] Since a group of first clamping blocks 3 are composed of multiple first clamping blocks 3, and every two first clamping blocks 3 can be rotatably connected, the device can change the angle when used at the corner, and can be bent when the device is wound, so as to facilitate subsequent winding.
