However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted. Specific implementation method one:

[0024] See Figure 1-Figure 4 As shown, this specific embodiment adopts the following technical scheme: it includes a mounting base 1, a limiting slide rail 2, a frequency converter fixed base 3, and a supporting guide wheel frame 4; a pair of limiting slide rails 2 are fixed on the front and rear sides of the mounting base 1; the frequency converter fixed base 3 is connected to the mounting base 1 through the cooperation of the supporting guide wheel frame 4 and the limiting slide rail 2; wherein, a rotating motor 6 is connected to the middle of the bottom of the frequency converter fixed base 3 through a fixed bracket 5, and a driving gear plate 7 is connected to the output shaft of the rotating motor 6, and four groups of transmission screws 9 are respectively fixed on the diagonal lines of the bottom of the frequency converter fixed base 3, and the inner top end of the transmission screw 9 is kept in meshing with the driving gear plate 7 through a gear 8; a movable slider 10 is screwed on the transmission screw 9, and the movable slider 10 is embedded in the reserved groove on the surface of the frequency converter fixed base 3 and connected to the transmission screw 9.

[0025] Among them, the rotating motor 6 drives the driving gear plate 7 to rotate, and with the cooperation of the gear 8 and the transmission screw 9, the movable slider 10 is gathered inward for clamping and fixing; the movable slider 10 is composed of a right-angle limit stopper 101, an anti-slip hook 102, a bottom support 103, and a screw hole slider 104; a pair of anti-slip hooks 102 are respectively arranged on the inner side of the right-angle limit stopper 101, the bottom of the right-angle limit stopper 101 is connected to the bottom support 103, and the lower end of the bottom support 103 is connected to the screw hole slider 104; the right-angle limit stopper 101, the anti-slip hook 102, the bottom support 103, and the screw hole slider 104 are an integrated structure.

[0026] In addition, an adjustment pad 11 is provided in the middle of the inverter fixing base 3, and the adjustment pad 11 supports the center of the inverter; the anti-slip barb 102 is engaged with the buckle holes reserved on the outer sides of the four corners of the inverter to form an anti-slip structure.

[0027] The working principle of this specific implementation method is as follows: first, place the frequency converter in the middle of the frequency converter fixed base 3, and adjust the height by adjusting the pad 11; then drive the rotary motor 6 to rotate, and the rotary motor 6 synchronously drives the driving gear plate 7 to rotate, and the driving gear plate 7 drives the transmission screw 9 to rotate synchronously through the meshing action with the gear 8.
