There are two connecting blocks 221, and the two connecting blocks 221 are respectively located on the two sections of threads, so that the size of the protective structure formed by the protective assembly 2 can be flexibly adjusted to meet the application of different actual usage scenarios. The first cover body 21 and the second cover body 23 are both semicircular.

[0025] The supporting structure includes a base plate 1, a universal wheel 4, a column 6, a connecting bracket 7 and a screw rod 8; the column 6 is fixedly installed on the upper surface of the base plate 1, the universal wheel 4 is arranged on the bottom surface of the base plate 1, the connecting bracket 7 is slidably arranged on the column 6, the screw rod 8 is rotatably arranged inside the column 6 and is threadedly connected to the connecting bracket 7, and a reinforcing rod is arranged on the connecting bracket 7, which is fixedly connected to the first cover body 21 to improve the rigidity of the overall device and thereby ensure stability during use.

[0026] The first movable cover 22 is provided with a connecting assembly 5 for connecting with the second movable cover 24. The connecting assembly 5 includes a fixed cylinder 51, a rotating shaft 52, a reset torsion spring 53, a fixed ring 54, an insert block 55 and a connecting rod 56. The fixed cylinder 51 is fixedly installed on the first movable cover 22 and plugged with the second movable cover 24. The rotating shaft 52 is rotatably arranged on the first movable cover 22. Both ends of the reset torsion spring 53 are fixedly connected with the fixed ring 54 and the first movable cover 22 respectively. The fixed ring 54 is fixedly installed on the rotating shaft 52. The insert block 55 is slidably arranged. It is placed on the fixed cylinder 51 and plugged into the second movable cover 24, and the two ends of the connecting rod 56 are movably connected to the plug block 55 and the rotating shaft 52 respectively. The fixed ring 54 is located in the internal cavity of the rotating shaft 52, and the cross-sectional area of ​​the fixed ring 54 is larger than the cross-sectional area of ​​the rotating shaft 52, which can ensure the tightness of the connection between the first movable cover 22 and the second movable cover 24, and thus ensure that the protective structure formed by the overall device can be stably and reasonably adjusted. At the same time, the entire connecting assembly 5 has a simple structure and is easy to operate, which can effectively improve the use efficiency of the overall device.

[0027] Working principle: before the micro-concave roller is disassembled, the screw rod 8 is rotated, and the connecting bracket 7 sliding on the column 6 is also fixedly connected to the first cover body 21, and the connecting bracket 7 is also threadedly connected to the screw rod 8. As the screw rod 8 rotates, the connecting bracket 7 will drive the first cover body 21 to slide up and down until the first cover body 21 reaches a suitable height, and the overall position is adjusted by using the universal wheel 4 fixed on the bottom plate 1. With the cooperation of the universal wheel 4 and the rotating screw rod 8, the center seat 26 fixed on the first cover body 21 can be brought into contact with the micro-concave roller body 3. At this time, the fastening belt 27 fixed on the center seat 26 and the buckle 2 fixed on the fastening belt 27 are used. 8 The position of the micro-concave roller body 3 is limited on the central seat 26. Since the first cover body 21 and the second cover body 23 are movably connected by the hinge 29, the second cover body 23 can be closed with the first cover body 21 to form a cylindrical structure larger than the micro-concave roller body 3. At the same time, the micro-concave roller body 3 is wrapped inside it to avoid bumping into the micro-concave roller body 3 during disassembly. When the second cover body 23 contacts the first cover body 21, the rotating shaft 52 is rotated, and the insert block 55 sliding on the fixed cylinder 51 uses the connecting shafts at both ends of the connecting rod 56 to be movably connected with the rotating shaft 52. Therefore, after the rotating shaft 52 is rotated, the insert block 55 will move toward the fixed cylinder 5 1, at this time, the fixed cylinder 51 fixed on the first movable cover 22 is inserted into the second movable cover 24, and then the rotating shaft 52 is loosened. Since the fixed ring 54 is fixed on the rotating shaft 52, and under the action of the return torsion spring 53 fixedly connected to the fixed ring 54 and the first movable cover 22 at both ends, the rotating shaft 52 is reversed, causing the connecting rod 56 to slide toward the outside of the fixed cylinder 51 until it is inserted into the second movable cover 24, and the second movable cover 24 is connected to the first movable cover 22. Since the first movable cover 22 slides on the first cover body 21, the second movable cover 24 slides on the second cover body 23, and the threaded rod 25 is fixed on the first cover body 2 1 is in a rotatable state, and the connecting block 221 fixed on the first movable cover 22 is threadedly connected to the threaded rod 25, and the threaded rod 25 is provided with two sections of threads with opposite spiral directions, which are respectively connected to the two connecting blocks 221. At this time, after the threaded rod 25 is rotated, the two connecting blocks 221 will be used to cause the two first movable covers 22 to drive the two second movable covers 24 to slide in a mirror image, thereby changing the size of the cylindrical structure used to provide protection for the micro-concave roller body 3, so as to be suitable for the application of micro-concave roller bodies 3 of different sizes. At this time, when the fasteners between the micro-concave roller body 3 and the coater are removed, collision can be avoided.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
