Currently, the current sensor is usually tested one by one by a staff member holding a current and voltage meter. Manual testing is slow and laborious. For this reason, the present application proposes a testing mechanism for a current sensor to solve the above problems. Utility Model Content

After the test is completed, the data is compared with the poor current sensor body placed in the inner cavity of the drawer to avoid data errors.

[0010] As a preferred embodiment, two limit grooves are symmetrically arranged on the top of the operating table, and two limit blocks are symmetrically fixedly assembled on the bottom of the movable seat, and the two limit blocks are slidably connected to the inner wall positions of the two limit grooves.

[0015] By adopting the above technical solution, the stability of the threaded rod during rotation can be guaranteed, and it can be guaranteed that it will not be randomly offset or shaken in position, and thus the moving seat and the current sensor body can be stably driven to move during rotation to achieve position adjustment.

At this time, the current and voltage of the current sensor body can be automatically tested without manual operation by the staff, saving time and effort. At the same time, the data will be fed back to the display screen for recording, and the data of the current sensor body of poor quality can be recorded. After the test is completed, the data will be checked with the poor current sensor body placed in the inner cavity of the drawer to avoid data errors.

[0018] 2.

When not testing, the tools used in the operation can be stored to ensure that the tools will not swing at will, thereby ensuring the cleanliness of the operating table surface.

[0027] See also Figure 1 and Figure 2 A support rod 16 is fixedly installed on the outer side of the operating table 1, and a display screen 17 is fixedly installed on the top of the support rod 16. The display screen 17 is electrically connected to the test needle 5, and the controller 15, the motor 8 and the cylinder 3 are all electrically connected, so that after the test needle 5 detects the current and voltage of the current sensor body 14, the data can be fed back to the display screen 17 for recording, and then the data of the current sensor body 14 of poor quality can be recorded. After the test is completed, the data is compared with the poor current sensor body 14 placed in the inner cavity of the drawer 19 to avoid data errors.
