[0024] Through the support assembly 6, the support motor 10 drives the first bevel gear 11 to rotate as a whole, and the first bevel gear 11 and the second bevel gear 12 are meshed and transmitted, so that the second bevel gear 12 rotates as a whole, and the second bevel gear 12 drives the rotating rod 7 to rotate as a whole, and the rotating rod 7 and the slider 8 are threadedly matched, so that the slider 8 moves as a whole, and in the process of the movement of the slider 8, the support rod 9 is driven to be propped up, so that the support platform 3 is pushed, and after the sensor is processed, the installed device placed on the top of the support platform 3 can be taken out as a whole, and the situation that the installed receiving sensor is not convenient to be taken out from the receiving cavity 2 is avoided as much as possible.

[0025] The four corners of the outer edge of the assembly platform 1 are all provided with fixing ears 5, and fixing holes 51 are provided on the fixing ears 5. The fixing ears 5 can ensure that the assembly platform 1 can be stably fixed at the corresponding position during the working process.

[0026] Reference Figure 1 , Figure 3 and Figure 4 As shown, a clamping assembly 13 for assisting sensor clamping and positioning is symmetrically installed at the outer edge of the top of the assembly table 1.
