[0026] The support frame includes a tripod 1 8 and a tripod 2 9, which are respectively located on both sides of the mechanical arm 1. The inner side of the tripod 1 8 is provided with a mounting groove 6 for mounting multiple gear blocks 4. The driving device includes a driving motor 10, a gear 2 11 and a rack 12. The driving motor 10 is fixedly arranged inside the mechanical arm base 14, one side of the gear 2 11 is fixedly connected to the output end of the driving motor 10, the rack 12 is vertically arranged on the inner side of the tripod 2 9, the gear and the rack 12 are meshed with each other, and the rack 12 is fixedly connected to the tripod 2 9 through multiple mounting rods 13. Slots 15 matching the tripod 1 8 and the tripod 2 9 are respectively provided on both sides of the mechanical arm 1, and the mechanical arm 1 can move between the tripod 1 8 and the tripod 2 9.

[0027] The working principle provided by the utility model is as follows: the gear 2 11 is driven to rotate by the driving motor 10. Because the gear 2 11 is meshed with the rack 12, and the rack 12 is vertically arranged on the inner side of the tripod 2 9, when the gear 2 11 rotates, it will rise and fall along the rack 12, and at the same time drive the driving motor 10 and the robot arm base 14 to move.

Therefore, when the gear 2 11 is raised and lowered on the surface of the rack 12, the drive motor 10, the robot arm base 14 and the robot arm 1 can be driven to rise and fall synchronously, because the rack 12 is connected to the inner side of the tripod 2 9 through multiple mounting rods 13, which is convenient for taking it out from the inner side of the tripod 2 9 for maintenance and repair.
