At this time, the handle on the front surface of the L-shaped upper cover 3 can be pulled to pull the L-shaped upper cover 3 outward, and the battery pack 2 and the circuits inside the protective box 1 are exposed. At this time, the interior can be inspected and repaired. Through the setting of the clamping device, when the power supply needs to be inspected, the clamping device can be opened by pressing the handle 16, and the L-shaped upper cover 3 can be pulled out, which makes it more convenient to disassemble the protective box 1 outside the power supply and facilitate the inspection of the inside of the power supply.

After charging, the current in the battery pack 2 is used to charge the device that needs to be charged through the socket 14. However, when the power supply needs to be repaired, since the plug 18 and the socket 14 are fixedly installed on the protective box 1 and are slidably connected to the L-shaped upper cover 3, when the L-shaped upper cover 3 is pulled out, it will not affect the internal circuit of the power supply, thereby improving the efficiency of the repair.

[0062] Working principle: When using the power supply, the battery pack 2 in the protection box 1 is charged through the plug 18. After charging, the current in the battery pack 2 is used to charge the device that needs to be charged through the socket 14. However, when the power supply needs to be repaired, the finger is inserted into the circular groove 7 in the rectangular protection block 6, and the push handle 16 located in the circular groove 7 is pressed inwardly. The push handle 16 slides into the installation groove 5, driving the rectangular plate 13 to move synchronously. The second spring 12 is squeezed by the rectangular plate 13 and compressed. The rectangular plate 13 moves inward and leaves the middle position of the two trapezoidal sliders 15. The rectangular plate 13 no longer squeezes the two trapezoidal sliders 15. The two first springs 11 on the inner walls on both sides of the installation groove 5 are no longer squeezed, and pressure is applied to the two sliding plates 10 to move the two sliding plates 10 toward the middle. The two trapezoidal sliders 15 move toward the middle synchronously, thereby driving the two clamping blocks 9 fixedly connected at the opposite ends of the two sliding plates 10 to move out of the clamping groove 8. The L-shaped upper cover 3 is no longer engaged with the inner part, and the handle on the front surface of the L-shaped upper cover 3 can be pulled to pull the L-shaped upper cover 3 and the sliding plates 19 fixedly connected on both sides of the cross plate thereof outwardly along the rectangular sliding groove 20, so that the battery pack 2 inside the protective box 1 and the circuits therein are exposed, and the interior can be inspected at this time. Moreover, since the plug 18 and the socket 14 are fixedly mounted on the protective box 1 and slidably connected with the L-shaped upper cover 3, when the L-shaped upper cover 3 is pulled out, the circuits inside the power supply are not affected, thereby improving the efficiency of inspection and maintenance. Through the setting of the engaging device, when the power supply needs to be inspected and maintained, the engaging device can be opened by pressing the handle 16, and the L-shaped upper cover 3 can be pulled out, so that the protective box 1 outside the power supply can be disassembled more conveniently, and the inside of the power supply can be inspected and maintained conveniently, and there is no need to unscrew the bolts one by one, which saves time, improves the inspection and maintenance speed, speeds up the inspection and maintenance progress, and improves the practicality of the power supply.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
