[0024] In this embodiment, an observation window 9 is fixedly installed on the movable cover 2, and an opening 10 is opened at the bottom of the observation window 9. The opening 10 is opened on the movable cover 2, and a groove 21 is opened on the inner wall of the opening 10. A protrusion 22 is movably installed inside the groove 21, and a button 11 is fixed at one end of the protrusion 22. The button 11 is movably installed inside the opening 10, and a reset mechanism 23 is fixed between the protrusion 22 and the groove 21. A fixed groove 19 is opened on the top of the movable cover 2, and a fixed block 20 is movably installed inside the fixed groove 19. One end of the fixed block 20 is fixed on the inner wall of the movable plate 3, and the reset mechanism 23 is a reset spring. The reset spring pushes the button 11 to return to its original position later. Later, by pressing the button 11, one end of the button 11 contacts the switch 17 for control, which is convenient for adjusting the working state of the inverter 15 later.

[0025] In this embodiment, a tension mechanism 24 is fixed inside the fixing groove 19, one end of the tension mechanism 24 is fixed on the fixing block 20, a threaded hole is opened on the movable plate 3, a threaded column 5 is rotatably installed inside the threaded hole, one end of the threaded column 5 is movably contacted with the movable cover 2, a frequency converter 15 is fixedly installed on the base 1, a display screen 16 is fixedly installed on the frequency converter 15, a switch 17 is installed at the bottom of the display screen 16, the switch 17 cooperates with the button 11, the tension mechanism 24 and the support mechanism 14 are both spring structures, the spring pushes the device to return to its original position at a later stage, the support mechanism 14 moves upward through the movable block 13, and the movable block 13 pushes the movable cover 2 on the slider 18 to move upward, thereby squeezing the movable plate 3 to be limited at the bottom of the limit block 8 for limit fixing.

[0026] The device provides the required electric energy for the electrical appliances inside the device through an external power supply. When using the device, the frequency converter 15 is first fixedly installed on the base 1, and then the base 1 is fixed in the use position through the fixing hole 7. When the movable cover 2 is installed, the movable plate 3 is moved to one side to open the opening at the top of the movable cover 2. After the top of the movable cover 2 is opened, the movable cover 2 is slidably installed in the inside of the slide groove 6 through the slider 18. With one end of the slider 18, the slider 18 squeezes the movable block 13, and the support mechanism 14 at the bottom of the movable block 13 is compressed and shrinks. After shrinkage, the top of the movable cover 2 enters the bottom of the limit block 8, and the movable plate 3 is returned to its position to seal the top of the movable cover 2. At the same time, the support mechanism 14 moves upward through the movable block 13, and the movable block 13 pushes the slider 18 upward The movable cover 2 moves upward, thereby squeezing the movable plate 3 to be limited and fixed at the bottom of the limit block 8. When the movable cover 2 needs to be opened quickly later, the movable plate 3 is moved to one side, and the limit block 8 loses the limiting support for the movable cover 2. The movable cover 2 moves upward under the push of the supporting mechanism 14, so that the movable cover 2 is removed from the base 1. After the movable cover 2 is removed, the inverter 15 is completely exposed, which is convenient for the later maintenance of the inverter 15. When in use, the position of the button 11 blocks the position of the switch 17. When the switch 17 needs to be adjusted, it is necessary to push the button 11 with an object smaller than the diameter of the opening 10 to move the switch 17 to complete the touch and press, so as to avoid accidental contact with the switch 17 caused by external force, so as to facilitate the later adjustment of the working state of the inverter 15 by coordinating the button 11 with the switch 17.
