[0041] In specific implementation, the clamping structure of the existing conductive rail 10 is simulated by the clamping component 2. Specifically, when performing the vibration resistance detection of the conductive rail 10, the first mounting seat 31 is arranged at the middle position of the base 1, and the motor 32 is started. At this time, the motor 32 drives the eccentric wheel 33 to rotate through its output shaft. The eccentric wheel 33 converts the rotational driving force of the motor 32 into a reciprocating linear driving force. The eccentric wheel 33 drives the pushing head 34 to move back and forth, and continuously pushes the conductive rail 10 through the pushing head 34, so that the conductive rail 10 continuously vibrates. By checking the connection state between the clamping component 2 and the conductive rail 10, the high-frequency vibration resistance test treatment of the conductive rail 10 is completed. By setting the pushing head 34 as a square head, when the eccentric wheel 33 drives the pushing head 34 to move to abut against the conductive rail 10, the pushing head 34 can be rotated to the positive position under the action of the side wall of the conductive rail 10, and the conductive rail 10 is positively pushed, thereby improving the stability of the pushing head 34 for pushing the conductive rail 10 each time.

By setting the second waist-shaped hole 2111, the position of the second mounting seat 21 can be adaptively assembled. The locking bolt 23 passes through the clamping head 221 and is threadedly connected to the inner side of the first threaded waist-shaped hole 2121, thereby completing the connection process of the clamping head 221. By setting the first threaded waist-shaped hole 2121, the clamping head 221 can adaptively clamp according to the height of the conductive rail 10.

[0049] In specific implementation, the connecting bolt 42 shortens the distance between the two side connecting frames 41, so that the two side connecting frames 41 are both inserted into the top and bottom of the conductive rail 10. By the side connecting frame 41 squeezing the conductive rail 10, the connection stability of the side connecting frame 41, under the structural strength of the side connecting frame 41, enhances the structural stability of the conductive rail 10, thereby preventing the conductive rail 10 from deforming during the process of the pushing head 34 pushing the conductive rail 10, and further preventing the conductive rail 10 from being unevenly stressed, increasing the stability of the vibration resistance detection of the conductive rail 10.

[0050] As a preferred implementation manner, the side connecting frame 41 includes a plugging portion 411, and the plugging portion 411 is located on the opposite side of the two side connecting frames 41.

[0054] In specific implementation, each support frame 43 and the connecting plate 44 are connected by bolts, and then each support frame 43 and the side connecting frame 41 are connected by bolts. Under the supporting action of the support frame 43, the connection stability of the side connecting frame 41 is further increased.

[0055] As a preferred embodiment, it further includes an end clamping member 5. The end clamping member 5 includes a third mounting seat 51 and two clamping heads 52. Among them, the third mounting seat 51 is arranged on the base 1 and located at the end of the conductive rail 10; the two clamping heads 52 are both arranged on the third mounting seat 51 and are respectively located at the top and bottom of the conductive rail 10, and are inserted inside the assembly groove 101.

[0056] Specifically, when assembling the conductive rail 10, the conductive rail 10 can be adjusted to move and be inserted between the two clamping heads 52. At this time, both clamping heads 52 are inserted inside the assembly groove 101. Under the action of the two clamping heads 52, the conductive rail 10 is clamped and positioned, and at the same time, the connection stability of the end of the conductive rail 10 is increased, which is convenient for subsequent test processing of the conductive rail 10.

Adjust the height of the clamping head 52 so that the two clamping heads 52 clamp the top and bottom of the conductive rail 10. By limiting one end of the conductive rail 10 away from the third mounting seat 51, the clamping connection process of the conductive rail 10 is completed. At this time, the pushing head 34 is located on one side of the conductive rail 10.
