[0044] In this embodiment, a plurality of motor mounts 20 are provided on the substrate 30 for fixing a plurality of motors 10. The plurality of motors 10 are connected to the tuning screws on the cavity filter 90 to be tested through the motor drive shaft 40. The plurality of motors 10 rotate based on the received motor drive signal, thereby utilizing the rotation of the motor shaft to drive the motor drive shaft 40 to transmit torque, thereby controlling the plurality of tuning screws to adjust the parameters of the cavity filter 90 to be tested, thereby solving the problems of complex filter structure, slow manual debugging speed and poor debugging accuracy. Furthermore, by controlling the plurality of tuning screws through the plurality of motor drive shafts 40, the problems of small spacing between tuning screws and great debugging difficulty existing in small filters can also be solved.

[0045] In this embodiment, multiple sets of motor drive shafts 40 are connected to the tuning screws, so that the mechanical debugging device in this embodiment can be suitable for debugging the closely spaced debugging screws on small filters, and through the adjustable motor seat 20 and the motor drive shaft 40, the debugging position can be freely set in three-dimensional space during the specific debugging process, and it has strong universality for many different types of filters.

At this time, more motor seats 20 can be set on the second side and the fourth side of the substrate 30. Since each side is provided with two slots, the position of the screw in each slot can be adjusted to adjust the angle of the motor seat 20.

[0052] In one embodiment, the screws inserted into the first fixing groove 301 and the second fixing groove 302 may be M3 screws, which are inserted into the fixing grooves on the substrate and the motor base 20 in sequence, and are fixed with corresponding nuts on the motor base 20 .
