[0032] Please refer to Figures 1-5 , as an embodiment for adjusting the length of the whole support structure: a second screw rod 15 is rotatably arranged in the adjusting chamber 13, the second screw rod 15 is threadedly connected with the mounting seat 14, a driven bevel gear 16 is fixedly arranged on the second screw rod 15, the driven bevel gear 16 is meshingly connected with a driving bevel gear 17, a rotating rod 18 is rotatably arranged in the adjusting chamber 13, one end of the rotating rod 18 is fixedly provided with a rotating handle 19, the other end of the rotating rod 18 extends into the adjusting chamber 13 and is fixedly connected with the driving bevel gear 17, two limiting grooves 20 are arranged on the support seat 1, and a limiting block 21 is movably arranged in each limiting groove 20. The limiting block 21 is fixedly connected with the mounting seat 14.

[0033] Specifically, the rotating handle 19 is rotated, the rotating handle 19 drives the rotating rod 18 to rotate, the rotating rod 18 drives the driving bevel gear 17 to rotate, the driven bevel gear 16 drives the second screw rod 15 to rotate due to the meshing connection between the driving bevel gear 17 and the driven bevel gear 16, and the mounting seat 14 moves outward along the adjusting chamber 13 due to the threaded connection between the second screw rod 15 and the mounting seat 14, thereby adjusting the total length of the whole support device, so that it can be installed between two sliding seats with different spacings. When the mounting seat 14 moves, the mounting seat 14 drives the limiting block 21 to move along the limiting groove 20 to limit the mounting seat 14.

[0034] Please refer to Figures 1-5 , as a knob 22 fixed embodiment: the bidirectional screw 2 fixedly provided with knob 22, the knob 22 outside fixedly provided with gear ring 23, one of the support seat 1 side fixedly provided with annular fixed shell 24, the fixed shell 24 movably provided with movable ring 25, the movable ring 25 and fixed shell 24 between fixedly provided with a plurality of springs 26, the movable ring 25 side fixedly provided with moving ring 27, the moving ring 27 side through the fixed shell 24 fixedly provided with the limit shell 28 matched with the gear ring 23.

[0035] Specifically, when the bidirectional screw 2 needs to be rotated, push the limit shell 28, the limit shell 28 drives the moving ring 27 and the movable ring 25 to move, the spring 26 is compressed, at this time the limit shell 28 removes the limit of the gear ring 23, can rotate the knob 22, the knob 22 drives the bidirectional screw 2 and the gear ring 23 to rotate, when the knob 22 rotates to the end, release the limit shell 28, under the push of the spring 26, make the movable ring 25 drive the moving ring 27 and the limit shell 28 move back to the original position, at this time the limit shell 28 moves to the outside of the gear ring 23 and limits it.

[0036] In summary, the overall equipment in use:

[0037] When the length of the whole support device needs to be adjusted according to the distance between the two X axis linear module on the sliding seat, turn the handle 19, the handle 19 drives the rotating rod 18 to rotate, the rotating rod 18 drives the driving bevel gear 17 to rotate, because the driving bevel gear 17 and the driven bevel gear 16 are meshed connection, make the driven bevel gear 16 drive the second screw 15 to rotate, because the second screw 15 and the mounting seat 14 are screw connection, make the mounting seat 14 move outward along the adjusting chamber 13, so as to adjust the total length of the whole support device, so as to be installed between two sliding seats with different spacing, when the mounting seat 14 moves, the mounting seat 14 drives the limit block 21 to move along the limit groove 20 to limit the mounting seat 14.

[0038] When the entire device needs to be used, the entire device is installed on the sliding seat of the two X-axis linear modules through the two mounting seats 14, and a Y-axis linear module is arranged above the two X-axis linear modules. The specific structure, working principle and connection relationship of the X-axis linear module and the Y-axis linear module, and the mounting mode of the mounting seat 14 to the sliding seat (not shown in the drawing) have been disclosed in the patent with the publication number CN214155309U and the patent name of a linear module adjustable support mechanism, which belongs to the prior art and will not be described here. When the bidirectional screw 2 needs to be rotated, the limiting shell 28 is pushed, the moving ring 27 and the movable ring 25 are moved under the action of the limiting shell 28, and the spring 26 is compressed. At this time, the limiting shell 28 releases the limiting of the tooth ring 23, and the knob 22 can be rotated. The knob 22 drives the bidirectional screw 2 and the tooth ring 23 to rotate. When the rotation of the knob 22 is completed, the limiting shell 28 is loosened, and under the pushing of the spring 26, the movable ring 25 drives the moving ring 27 and the limiting shell 28 to move back to the original position. At this time, the limiting shell 28 moves to the outside of the tooth ring 23 to limit and fix it.

[0039] When the Y-axis linear module needs to be supported, the bidirectional screw 2 is rotated by rotating the knob 22. The bidirectional screw 2 is provided with two opposite threaded areas, so that the two adjusting seats 3 move in the adjacent direction. The adjusting seat 3 drives the push plate 5 to rotate, so that the push plate 5 rotates and pushes the support plate 4 upward at the same time. The support plate 4 moves upward and contacts the lower end of the Y-axis linear module to support it. The entire device moves during use, the roller 12 rotates, thereby supporting the Y-axis linear module. When the roller 12 is damaged, the first screw 8 is rotated. Since the first screw 8 is in threaded connection with the second limiting plate 9, the second limiting plate 9 moves. The second limiting plate 9 drives the bearing 10 arranged thereon to separate from the plug rod 11. The roller 12 is pulled to separate the other plug rod 11 from the bearing 10, so that the roller 12 can be disassembled. The replaced roller 12 can be installed by using the opposite operation.

[0040] In all the schemes mentioned above, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut cooperation connection, bolt or screw connection or other known connection mode. In this regard, the welding is preferred, although the embodiments of the utility model have been shown and described. For ordinary skilled persons in the art, it can be understood that the embodiments can be changed, modified, replaced and modified in various ways without departing from the principles and spirits of the utility model. The scope of the utility model is defined by the appended claims and their equivalents.
