[0002] According to the publication number "CN216800367U", the height of the coating roller is roughly adjusted by the lifting cylinder, and then the height of the coating roller is finely adjusted by the positioning component, so that it can meet the needs of coating protective films of different thicknesses. At the same time, the buffer component is used to squeeze the coating roller so that it is close to the surface of the protective film coating.

[0003] In the process of implementing this solution, the inventors found that the following problems existed in the prior art and have not been well solved: although this adjustment method can be implemented, the spacing between adjacent fixing holes is large, and the positioning column used for fine adjustment is limited by inserting into the fixing hole. This limiting method will not be able to conceal fine adjustment due to the large spacing between adjacent fixing holes. Utility Model Content

[0023] Specifically, the length of the threaded column 7 is greater than the length of the internal threaded tube 4 , and the length of the sliding column 8 is greater than the length of the sliding tube 5 .

[0024] Specifically, the bottom of the threaded column 7 is rotatably connected to the top of the fixed cylinder 6 , and the top of the sliding column 8 is fixedly connected to the top of the fixed cylinder 6 .

[0025] Specifically, an adjusting head 10 is fixed to the top of the threaded column 7 , and a plurality of inserting holes 101 are drilled through the side wall of the adjusting head 10 , and components such as a pry bar can be inserted into the inserting holes 101 , thereby facilitating the threaded column 7 to rotate.

[0026] Specifically, the length of the block tooth plug-in 9 is greater than the internal length of the block tooth inner groove 81, and the two ends of the screw rod 91 located outside the block tooth inner groove 81 are respectively inserted into the inside of the block tooth outer groove 51, and the two sides of the block tooth plug-in 9 are respectively meshed and connected with the block tooth outer groove 51 and the inner side wall of the block tooth inner groove 81, the internal height of the block tooth inner groove 81 is greater than the internal height of the block tooth outer groove 51, and the internal height of the block tooth outer groove 51 is greater than the height of the block tooth plug-in 9, the screw rod 91 is respectively connected with the block tooth outer groove 51, and the adjacent sides of the two nuts 92 are respectively in contact with the outer side wall of the slide 5, so that the adjusted height can be stably limited.

[0027] Specifically, sleeves 11 are fixed at both ends of the bottom of the mounting plate 1, and a spring 12 is fixed at one end of the mounting plate 1 located inside the sleeve 11.

[0028] Working principle:

[0029] After rotation, the threaded column 7 can be lifted and lowered. The rotational connection between the threaded column 7 and the fixed cylinder 6 at that position and the sliding connection between the sliding column 8 on the top of the other fixed cylinder 6 and the sliding cylinder 5 enable the two fixed cylinders 6 to be lifted and lowered horizontally. Compared with the prior art, this adjustment method can achieve better fine adjustment. After the adjustment is completed, the block tooth plug-in 9 can penetrate the block tooth outer groove 51 and the block tooth inner groove 81, thereby achieving the effect of meshing connection and completing the initial limit. The screw rod 91 will pass through the block tooth outer groove 51 and be located outside it before being threadedly connected with the nut 92. The nut 92 clamps the outer wall of the sliding cylinder 5, thereby completing the clamping limit and achieving the effect of stable fixation. Since the inner height of the block tooth inner groove 81 is greater than the inner height of the block tooth outer groove 51, and the inner height of the block tooth outer groove 51 is greater than the height of the block tooth plug-in 9, the height of the limit of the block tooth plug-in 9 can be adjusted at will, and there will be no situation where the limit cannot be made due to the spacing problem of the limit parts.
