The bottom end of the transmission component is detachably connected with the driving gear 9, and the driving gear 9 of different sizes can be replaced. The outer wall of the driving gear 9 is meshed with a slideway 2, and the inner side of the slideway 2 is provided with an inner rack 3. The inner wall of the inner rack 3 is meshed with the outer wall of the driving gear 9. When the driving gear 9 rotates, it will drive the driving plate body 4 to slide on the truss 1. The bottom of the slideway 2 is fixedly connected to the truss 1, and the inner wall of the driving plate body 4 is rotatably connected with a screw. The threaded rod 10 has a knob 16 fixedly connected to the end of the threaded rod 10. The threaded rod 10 can be rotated by turning the knob 16. The outer wall of the threaded rod 10 is threadedly connected to a threaded sleeve 11. The inner walls of the two sets of threaded sleeves 11 are provided with reverse threads, which move closer to or separate from each other as the threaded rod 10 rotates. The outer wall of the threaded sleeve 11 is hinged with a bracket 12. When the angle of the threaded sleeve 11 changes, the angle of the bracket 12 will change. The end of the bracket 12 is hinged with a rectangular plate 14. The inner wall of the driving plate body 4 is fixedly connected to a guide rod 13. The outer wall of the guide rod 13 is connected to the inner wall of the driving plate body 4. The inner wall of the rectangular plate 14 is slidably connected, and the angle change of the bracket 12 will pull the rectangular plate 14 to slide along the guide rod 13, so that the two groups of rectangular plates 14 are brought closer to or separated from each other. The pulley 15 is rotatably connected on the axis of the outer wall of the rectangular plate 14, and the outer wall of the pulley 15 is slidably connected to the outer wall of the slide 2. The rectangular plate 14 drives the pulley 15 to stick to the outer side of the slide 2 to install the driving plate body 4 on the truss 1. There is a groove in the center of the pulley 15, and the outer side of the slide 2 is convex, which is just stuck, and slides on the outer wall of the slide 2 as the external position of the driving plate body 4 changes.

[0032] Reference Figure 1-Figure 3The outer wall of the driving plate body 4 is detachably connected to the manipulator base 17, and the outer wall of the driving plate body 4 is fixedly connected to the cylindrical block 19. The side wall of the manipulator base 17 is provided with a circular groove 18, and the outer wall of the cylindrical block 19 is plugged into the inner wall of the circular groove 18. The circular groove 18 is aligned with the cylindrical block 19 and put on to connect the manipulator to the driving plate body 4. The inner wall of the cylindrical block 19 is slidably connected to the pull rod 20, and the inner wall of the pull rod 20 is slidably connected to two groups of card blocks 22. The two groups of card blocks 22 are elastically connected by a reset spring 21. The outer wall of the card block 22 is set to an inclined surface. In the process of inserting the cylindrical block 19 into the circular groove 18, the inclined surface of the card block 22 on the inner wall of the circular groove 18 can squeeze the reset spring 2 1 is retracted. At the same time, the elastic force generated by the deformation of the reset spring 21 gives the block 22 a thrust in the opposite direction to reset it. The two ends of the reset spring 21 are respectively fixedly connected with the inner ends of the two groups of blocks 22. The bottom end of the block 22 contacts the side wall of the driving plate body 4. After the column block 19 is fully inserted into the circular groove 18, the block 22 pops out of the outer wall of the column manipulator base 17 to fix it on the driving plate body 4 for a preliminary installation. The outer wall of the block 22 contacts the inner wall of the column block 19. After pressing the block 22 inwards, pulling the pull rod 20 outwards can make the block 22 completely retracted while resisting the inner wall of the column block 19 to prevent it from popping out. At this time, the manipulator can be removed.

[0033] Working principle: When adjusting the position of the pulley 15 on the back of the driving plate body 4 according to the size of the truss 1, turn the knob 16 to rotate the threaded rod 10, so that the position of the threaded sleeve 11 changes, thereby driving the angle of the bracket 12 to change, and pulling the two sets of rectangular plates 14 to move closer to or separate from each other along the outer wall of the guide rod 13, thereby driving the pulley 15 to move closer to each other and stick to the outer wall of the slideway 2. At the same time, replace the driving gear 9 with a suitable size to clamp the inner rack 3 of the slideway 2, and then start the motor 5 to make the bevel gear a6 drive the bevel gear b7 to rotate, so that the shaft 8 drives the driving gear 9 to rotate Rotate, thereby controlling the driving plate body 4 to slide on the truss 1, and controlling the position change of the manipulator. When installing the manipulator, the circular groove 18 on the side wall plate of the manipulator base 17 can be aligned with the cylindrical block 19 and put on. In the process of inserting the cylindrical block 19 into the circular groove 18, the inner wall of the circular groove 18 squeezes the inclined surface of the card block 22 to squeeze the reset spring 21 to retract. When the cylindrical block 19 completely passes through the circular groove 18, the reset spring 21 pops out and buckles the outer wall of the manipulator base 17 to perform a preliminary installation, and then fix it with screws and nuts. There is no need for manual hand-held calibration, which improves installation efficiency.
