One end of the movable bidirectional screw passes through one of the movable support plates and is fixedly connected to a movable rotating block. Both assembly blocks are threadedly connected to the outer wall of the movable bidirectional screw. By rotating the movable rotating block, the movable bidirectional screw is driven to rotate. Then, the two assembly blocks move along the direction on the movable bidirectional screw, moving closer to or further away from each other.

[0008] As a further description of the above technical solution:

[0009] One of the movable support plates has multiple movable insertion holes on its side wall, and a movable insert is provided through the side wall of the movable rotating block. A movable pull block is fixedly connected to one end of the movable insert, and a movable spring is movably sleeved on the outer side wall of the movable insert. By releasing the movable pull block, the movable spring provides a restoring force to the movable insert.

[0010] As a further description of the above technical solution:

[0011] The two ends of the movable spring are fixedly connected to the side walls of the movable pull block and the movable rotating block, respectively. The other end of the movable insert is movably inserted into one of the movable holes. By movably inserting the movable insert into one of the movable holes, the movable rotating block is limited after adjustment.

[0012] As a further description of the above technical solution:

[0013] The fixing component includes a fixing recess fixedly connected to the side wall of the movable baffle. A fixing shaft is rotatably connected between the two sides of the inner wall of the fixing recess. A fixing U-shaped plate is fixedly sleeved on the outer wall of the fixing shaft.

[0017] The end of the fixed spring is fixedly connected to its corresponding fixed slider. A fixed pull plate is fixedly connected between the two fixed sliders. A fixed insert is fixedly connected to the bottom of the fixed pull plate. The end of the fixed insert is movably inserted into one of the assembly holes. By movably inserting the fixed insert into one of the assembly holes, the assembly recess and the movable recess are limited.

[0018] This utility model has the following beneficial effects:

[0019] Using the fixed component, the fixed pull plate can be used to separate the fixed insert from one of the assembly holes. Then, the fixed retaining plate can be pried open and flipped to separate the corresponding assembly rotating block inside the fixed retaining plate. Using the movable component, the movable rotating block can drive the movable bidirectional screw to rotate. Then, the two assembly blocks move closer or further apart along the direction on the movable bidirectional screw. At the same time, the assembly blocks are movably sleeved and guided by the assembly plate and the outer wall of the assembly cross plate. Then, the assembly blocks also drive the assembly recess and the moving recess on the assembly L-shaped plate to move, so that the two ends of the roller are separated from the assembly recess and the moving recess, thereby disassembling the roller, facilitating subsequent replacement, and improving the use effect.

The end of the fixed insert 23 is movably inserted into one of the assembly holes. The fixed components limit the two ends of the roller between the movable recess 15 and the assembly recess 6.

[0029] Working principle: When in use, first pull the fixed pull plate 22, which will cause the fixed insert 23 to separate from one of the assembly holes. Then, pry and flip the fixed shaped plate 19, so that the corresponding assembly block inside the fixed shaped plate 19 is separated. Then, push the moving baffle 14, so that the moving baffle 14 drives the moving support plate 13 and the moving spring 16 to move along the direction on the assembly recess 6. At the same time, the moving recess 15 on the moving support plate 13 also moves, so that the roller on the moving support plate 13 and the corresponding assembly recess 6 moves away from each other.

[0030] Next, pull the movable block 11, causing the movable block 11 to drive the movable insert 10 and the movable spring 12 to move along the direction on the movable rotating block 9. Then, the movable insert 10 separates from one of the movable insertion holes. Then, rotate the movable rotating block 9, causing the movable rotating block 9 to drive the movable bidirectional screw 8 to rotate. Then, the two mounting blocks 4 move away from each other along the direction on the movable bidirectional screw 8. At the same time, the mounting blocks 4 are movably sleeved and guided by the mounting plate 3 and the outer wall of the mounting cross plate 2. Then, the mounting blocks 4 also drive the mounting recess 6 and the moving recess 15 on the mounting L-shaped plate 5 to move, so that the two ends of the roller are separated from the mounting recess 6 and the moving recess 15.

[0031] During installation, first align the two ends of the roller with the corresponding grooves formed between the mounting recess 6 and the movable recess 15. Then, rotate the movable rotating block 9 again, causing the movable rotating block 9 to drive the movable bidirectional screw 8 to rotate. Then, the two mounting blocks 4 move closer to each other along the direction on the movable bidirectional screw 8. At the same time, the mounting blocks 4 are movably sleeved and guided by the mounting plate 3 and the outer wall of the mounting cross plate 2. Then, the mounting blocks 4 also drive the mounting recess 6 and the movable recess 15 on the mounting L-shaped plate 5 to move, so that the groove formed between the mounting recess 6 and the movable recess 15 is sleeved with the two ends of the roller.

[0032] Next, release the movable baffle 14, so that the movable spring 16 gives the movable support plate 13 a restoring force, so that the movable support plate 13 drives the movable baffle 14 to move the movable recess 15 toward the mounting recess 6 and limit the roller between the movable recess 15 and the mounting recess 6. Then release the fixed pull plate 22, so that the movable spring 12 gives the movable insert 10 on the movable pull block 11 a restoring force, and then the movable insert 10 is inserted into one of the movable holes and limited.

[0033] At the same time, the fixed retaining plate 19 is bent and flipped so that the inside of the fixed retaining plate 19 is engaged with the assembly rotating block. Then the fixed pull plate 22 is released so that the fixed spring 21 gives a restoring force to the fixed insert 23 on the fixed pull plate 22. Then the fixed insert 23 is engaged with one of the assembly holes and limited to move, thereby performing the disassembly and installation.
