Two first ear plates are fixed to the bottom of the support plate 100. The first rod 800 is rotatably mounted on the two first ear plates. The two ends of the first rod 800 are provided with threads with opposite directions of rotation. The two ends of the first rod 800 pass through the corresponding first slider 610 and are connected by threaded transmission.

[0048] In one specific embodiment of this utility model, such as Figures 1-3 As shown, the telescopic rod 200 is an electric cylinder, hydraulic cylinder, or pneumatic cylinder.

[0049] The movement of the L-plate is controlled by rotating the lever with a crank, which is simple, intuitive, and easy for staff to master.

[0050] The working process of this utility model:

[0051] Preparation: Make the central axis of the annular core 500 vertical and place it on the horizontal plates of the first L-plate 600 and the second L-plate 700. Rotate the first crank handle 810, which drives the first rod 800 to rotate. Since the threads at both ends of the first rod 800 rotate in opposite directions, the two first sliders 610, threadedly connected to the first rod 800, will slide relative to each other within the first through groove 130, causing the two first L-plates 600 to move closer or further apart until the vertical plates of the first L-plates 600 contact the left and right sides of the annular core 500. Rotate the second crank handle 1000, which drives the second rod 900 to rotate. Similarly, the two second sliders 710, threadedly connected to the second rod 900, will slide relative to each other within the second through groove 140, causing the two second L-plates 700 to move closer or further apart until the vertical plates of the second L-plates 700 contact the front and rear sides of the annular core 500, thus securely clamping the annular core 500.

[0052] During the testing process, the telescopic rod 200 is activated. The telescopic end of the telescopic rod 200 moves the mounting plate 210 and the male connector end 300 downwards, allowing the male connector end 300 to align with the female connector end 400, thus initiating performance testing of the toroidal core 500. During the testing process, the toroidal core 500 is firmly fixed by the clamping mechanism, effectively preventing it from tipping over or shaking due to external interference, thus ensuring the accuracy of the test results.

[0053] After the test is completed, the telescopic end of the telescopic rod 200 moves the mounting plate 210 and the male connector end 300 upwards, separating them from the female connector end 400. Then, the first crank 810 and the second crank 1000 are rotated in opposite directions to move the first L plate 600 and the second L plate 700 away from each other, releasing the clamp on the toroidal core 500. The tested toroidal core 500 can then be removed, completing one test process.

[0054] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0055] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
