A movable block 3 is disposed above the support platform 1. The adjusting mechanism 4 is disposed above the support platform 1 and includes a hollow block 401, a bidirectional threaded rod 402, an internal threaded block 403, and a mounting plate 405. The bidirectional threaded rod 402 is rotatably mounted on the inner walls of both sides of the hollow block 401. The outer wall of the bidirectional threaded rod 402 is threadedly connected to the inner threads of two sets of internal threaded blocks 403. A set of mounting plates 405 is fixedly mounted on the front side of each of the two sets of internal threaded blocks 403, extending to the outside of the hollow block 401. The wire fixing mechanism 5 is disposed on the top of the support platform 1 and is used for wire fixing. Mechanism 5 includes a fixed frame 502, a single threaded rod 503, and a pressure block 504. The top of the fixed frame 502 is threadedly connected to the outer wall of the single threaded rod 503. One end of the single threaded rod 503 extends into the interior of the fixed frame 502 and is rotatably mounted on the pressure block 504. A motor 7 is fixedly mounted on the bottom of the support platform 1. The output shaft of the motor 7 passes through the support platform 1 and is fixedly connected to the rotating support block 501. A connecting sleeve 2 is fixedly mounted on the top of the support platform 1. The inner wall of the connecting sleeve 2 is slidably connected to the outer wall of the movable block 3. Multiple sets of limiting holes are opened on the front side of the movable block 3. A bolt 8 is threadedly connected to the front side of the connecting sleeve 2. One end of the bolt 8 extends into the interior of a set of limiting holes. A timer 6 is fixedly mounted on the top of the support platform 1.

[0022] Secondly, the adjusting mechanism 4 also includes a first knob 404 and a positioning hole 406. The bottom of the hollow block 401 is fixedly connected to the top of the movable block 3. One end of the bidirectional threaded rod 402 extends to the outside of the hollow block 401 and is fixedly installed with the first knob 404. The inner wall of the hollow block 401 is slidably connected to the outer wall of the two sets of internal threaded blocks 403. The top of the mounting plate 405 has multiple sets of positioning holes 406, which can adjust the distance between the two sets of mounting plates 405 according to the different conductive slip rings, so that the positioning holes 406 can match the reserved holes of conductive slip rings of various sizes, ensuring the normal installation of different conductive slip rings, increasing the usability of the device, and improving the flexibility and practicality of the device.

[0023] Furthermore, the wire fixing mechanism 5 also includes a rotating support block 501 and a second knob 505. The rotating support block 501 is rotatably mounted on the top of the support platform 1, and a fixing frame 502 is fixedly mounted on the top of the rotating support block 501.

[0024] Working principle: When in use, the device rotates the bidirectional threaded rod 402 via the first knob 404. Under the limitation of the inner wall of the hollow block 401, it drives the two sets of internal threaded blocks 403 to move in opposite directions, thereby adjusting the distance between the two sets of mounting plates 405. Based on the reserved hole position of the cap-type conductive slip ring, the position of the positioning hole 406 is adjusted, and the conductive slip ring is placed on the mounting plate 405. The conductive slip ring is then installed on the mounting plate 405 by screws passing through the positioning hole 406 and the reserved hole. The conductor at the rotor end passes through the fixed frame 502. The single threaded rod 503 is rotated by the second knob 505. Under the limit of the inner wall of the fixed frame 502, the pressure block 504 moves downward and presses on the conductor, fixing the conductor on the rotating support block 501. At the same time, the lead wire is connected to the test equipment. The motor 7 is turned on to drive the rotating support block 501 to rotate, which drives the rotor end of the conductive slip ring to rotate continuously. The timer 6 is used to keep track until the signal transmission of the guide ring slip ring is interrupted, and the life of the conductive slip ring is calculated.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
