It converts primary energy from nature into electricity through mechanical energy devices, and then supplies electricity to various users through transmission, transformation and distribution. Voltage is one of the important components of the power system.

[0003] Taking the working power supply as an example, in order to ensure the subsequent working performance after the working power supply is produced, it is necessary to perform certain tests on the stability of its output voltage. However, the existing voltage detection device can only measure the voltage of the working power supply when it is static during use, and cannot simulate environmental changes. Therefore, it is difficult to detect the stability of the output voltage of the working power supply in different environments, which makes the detection limited. Therefore, a detection device that can simulate different environments and detect the stability of the working power supply voltage in different environments is needed. The utility model solves this technical problem. Utility Model Content

[0023] Furthermore, the buffer mechanism includes an upper support plate 2 connected to a ball joint with a ball head rod 11, a spring 4 connected to the top end of the upper support plate 2, and a lower support plate 3 connected to the bottom end of the spring 4. The lower support plate 3 is connected to the height adjustment mechanism, and a clamping block 6 is detachably connected between the upper support plate 2 and the placement box 10, and the clamping block 6 is used to clamp the ball head rod 11.

[0024] In this embodiment, two clamping blocks 6 are provided, and the sides of the two clamping blocks 6 are provided with grooves matching the shape of the ball head rod 11. When the sides of the two clamping blocks 6 are docked, the ball head rod 11 can be clamped in the groove, thereby completing the clamping of the ball head rod 11.

[0028] The working principle of the utility model is as follows:

[0029] First, put the working power supply into the placement box 10, and connect it to the voltage detection meter 9 through the wire, then start the four electric push rods 5 at the same time. Under the action of the electric push rods 5, the working power supply will be driven to move up and down. Due to the presence of the spring 4, the working power supply will have a small swing.
