[0032] One end of the pressing cover 5 is fixedly connected with a pressing shaft 6, which is designed to transmit the force received by the pressing cover 5 to the inside. The outside of the pressing shaft 6 is sleeved with a compression spring 7, which is designed as a reset buffer. The inside of the sliding cylinder 4 is fixedly connected with a fixed shaft 8, which is designed to provide a fixed support point for subsequent components. The outside of the pressing shaft 6 is slidably connected to the inside of the fixed shaft 8. The other end of the compression spring 7 is fixedly connected to the inside of the fixed shaft 8. One end of the pressing shaft 6 is fixedly connected with a trapezoidal column 9, which is designed to lock and unlock the subsequent components. The inside of the sliding cylinder 4 is coupled with two clamping balls 10, which are designed to lock and unlock the sliding cylinder 4 and other components. The outside of the plurality of clamping balls 10 is coupled to the outside of the trapezoidal column 9. The inside of the workbench 1 is fixedly connected with a rotating assembly for multi-angle rotation of the mechanical arm

[0033] Referring to Figure 3 , Figure 4 , the rotating assembly comprises a driving device 13, which is designed as the power core of the rotating assembly. The outside of the driving device 13 is fixedly connected to the inside of the workbench 1. The inside of the workbench 1 is provided with a sliding groove 12, which is designed as a motion guide. The driving end of the driving device 13 is fixedly connected with a gear block 14, which is designed to have high stability and accuracy when transmitting power. The bottom of the gear block 14 is fixedly connected with a sliding block 15, which is designed to constrain the motion of the gear block 14.

[0035] Working principle: When different scanning devices need to be replaced according to different work requirements, the pressing cover 5 is pushed to push the pressing shaft 6, which in turn squeezes the compression spring 7, so that the pressing shaft 6 passes through the fixed shaft 8 fixedly connected inside the inner sliding cylinder 4 and slides in the fixed shaft 8. At this time, the trapezoidal column 9 is pushed by the pressing shaft 6 and enters the deep interior of the sliding cylinder 4. At this time, due to the trapezoidal shape of the trapezoidal column 9, the two locking balls 10 are no longer squeezed, so the locking balls 10 are no longer engaged with the support block 3. Then the sliding cylinder 4 and the externally fixed imaging device 11 are taken out, and a different imaging device 11 is replaced. The locking balls 10 are pushed back into the support block 3. At this time, the pressing cover 5 is released, the compression spring 7 releases its elasticity, and pushes the pressing cover 5 to slide outward, thereby controlling the trapezoidal column 9 to squeeze the locking balls 10 and engage them with the support block 3 again, achieving a fast and stable replacement of different scanning devices.

[0036] When it is necessary to control the robotic arm to perform scanning work at different angles, the drive device 13 is activated, the drive end pushes the gear block 14, and the bottom binding block 15 slides stably in the binding groove 16 to constrain the motion trajectory. During the movement of the gear block 14, it meshes with the gear shaft 17, controls the rotation of the gear shaft 17, and then drives the support plate 18 to rotate the connected robotic arm 2, which rotates on the top of the worktable 1, and then scans the top of the worktable 1 at multiple angles.
