[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a low-voltage debugging tool includes an upper clamping plate 1. Connecting blocks 101 are provided on both sides of the upper clamping plate 1, and a limiting slide rod 2 is slidably installed on the upper surface of the connecting blocks 101. The advantage of this setting is that the compression direction of the buffer spring 201 can be limited by the setting of the limiting slide rod 2, thereby improving the service life of the buffer spring 201.

[0022] Furthermore, a limiting plate 202 is provided on the upper surface of the limiting slide bar 2, and a buffer spring 201 is provided on the upper outer surface of the limiting slide bar 2. The advantage of this setting is that, by setting the buffer spring 201, when the upper clamping plate 1 and the lower clamping plate 302 clamp the object, the clamping force received can be buffered by compression, so as to avoid excessive downward pressure of the threaded rod 301 and damage to the object.

[0023] Furthermore, a connecting block 203 is provided on the lower end surface of the limiting slide bar 2, and a buffer plate 204 is provided on the front end surface of the connecting block 203. The advantage of this setting is that the pressure caused by the downward pressure can be reduced by the setting of the buffer plate 204.

[0024] Furthermore, a limiting slide bar 3 is provided on the lower rear surface of the upper clamping plate 1, and a lower clamping plate 302 is slidably mounted on the surface of the limiting slide bar 3. A threaded rod 301 is spirally mounted on the upper surface of the lower clamping plate 302, and the threaded rod 301 is rotatably connected to the upper clamping plate 1. The advantage of this setting is that the lower clamping plate 302 can be controlled to move upward to clamp the object by setting the threaded rod 301.

[0025] Furthermore, a support rod 404 is provided on the upper surface of the rotating shaft 4, and a sleeve rod 405 is provided on the front surface of the support rod 404. A terminal rod 406 is slidably mounted on the outer surface of the sleeve rod 405. This configuration is an existing device and will not be described in detail.

[0026] like Figure 4 As shown, a rotating shaft 4 is rotatably mounted on the upper surface of the upper clamping plate 1, and a friction pad 401 is provided at the bottom of the rotating shaft 4. A threaded groove 402 is provided on the outer surface of the rotating shaft 4, and a rotating sleeve 403 is spirally mounted on the outer surface of the threaded groove 402. The rotating sleeve 403 and the friction pad 401 are configured as a friction connection. The advantage of this configuration is that, through the setting of the rotating sleeve 403, the rotating shaft 4 can rub against the friction pad 401 through the threaded groove 402 on the surface of the rotating shaft 4, thereby fixing the terminal rod 406 after angle adjustment.

[0027] Working principle: When using this low-voltage debugging tool, firstly, rotating the threaded rod 301 causes the lower clamping plate 302 to slide upward along the limiting slide bar 3 to clamp the object. At the same time, the buffer plate 204 contacts the surface of the object and presses the buffer spring 201 backward to compress and buffer the downward pressure on the object. After clamping the equipment, the angle of the terminal rod 406 is adjusted by rotating the shaft 4. Then, the rotating sleeve 403 is screwed into the threaded groove 402 on the surface of the rotating shaft 4, so that it rubs against the friction pad 401 to fix the rotating shaft 4. Then, the low-voltage test is performed. This is the working principle of this low-voltage debugging tool.
