[0038] Fixed block 19: used to limit the movement of the pressing plate 16 on the limiting screw 18, when it is necessary to fix the workbench 2, tighten the fixed block 19 to press the pressing plate 16, so as to fix the pressing plate 16 on the limiting screw 18, and realize reliable restriction of the workbench 2;

[0039] Fixed groove 17: ensures that the pressing plate 16 can stably play a role when fixing the workbench 2, and will not rotate due to external force and other factors, affecting the restriction effect on the workbench 2.

[0040] Rotary screw 9: provides rotary connection shaft for guide rail 5, and is also the installation basis of threaded cap 10. Through the threaded cooperation with threaded cap 10, the guide rail 5 is fixed, avoiding the disconnection between the guide rail 5 and the mounting block 4. Threaded cap 10 is located inside the groove 11 to avoid affecting the sliding of the workbench 2 on the guide rail 5.

[0041] Guide plate 12: its function is to limit the movement path of the limiting plate 8, ensure that the limiting plate 8 slides along the predetermined track on the guide rail 5, so as to ensure that the limiting plate 8 can accurately cooperate with the threaded rod 6, realize the fixation and position limitation of the guide rail 5, and improve the stability and reliability of the device;

[0042] Support frame 13 plays the role of connecting guide rail 5 and rubber block 14. When the device is working normally, the rubber block 14 contacts with the ground, plays the role of support and shock absorption, and increases the stability of the device. When the device needs to be moved, rotate the rubber block 14 to make it away from the ground, avoid the influence of the rubber block 14 on the rotation of the guide rail 5, and facilitate the movement and adjustment of the device.

[0043] Working principle:

[0044] First, when the need to move the device, turn the nut 7 with the connection of the nut 7 and threaded rod 6 is removed, at this time, pull the limit plate 8 with the connection of the limit plate 8 and threaded rod 6 is removed, at this time, turn the guide rail two 5 away from the end of the guide rail one 3 to the workbench 2, at this time, the limit plate 8 with the guide rail two 5 turn to another threaded rod 6, at this time, push the limit plate 8 limit plate 8 slip outside the threaded rod 6, at this time, the nut 7 threaded connection outside the threaded rod 6, so that the limit plate 8 fixed so that it cannot be removed with the connection of the threaded rod 6, at this time, the guide rail two 5 also cannot be rotated, while the end of the pressing plate 16 into the fixed slot 17 inside, the other end of the slip connection outside the limit screw 18, at this time, the fixed block 19 threaded connection outside the limit screw 18 of the pressing plate 16, at this time, the workbench 2 is limited by the guide rail one 3 and the pressing plate 16 cannot be moved;

[0045] Second, in the process, turn the rubber block 14 away from the ground, so as to avoid the rubber block 14 influence the guide rail two 5 rotation.
