When the piece 21 is inserted into the slot 20, it first abuts against the inclined surface of the fixed wedge block 23, and the fixed wedge block 23 drives the plug 21 to deform. When the lower half box 101 and the upper half box 102 are completely spliced, the fixed wedge block 23 is aligned with the fixed through hole 22. At this time, the plug 21 rebounds and is fixedly installed in the slot 20. The control box 1 is divided into the upper half box 102 and the lower half box 101, which can facilitate the disassembly and assembly of the control box 1, thereby facilitating the inspection and maintenance of the control box 1.

The mounting frame 43 rotates the card connection block 10 to be connected to the fixing block 8 from the card interface 9, and a mounting block 11 is fixed on the mounting frame 43. The mounting block 11 is provided with a mounting hole 12, and a threaded hole 13 is provided on the control box 1. When the card connection block 10 is connected to the fixing block 8, the mounting hole 12 and the threaded hole 13 are aligned, and the bolt passes through the mounting hole 12 and is threadedly connected to the threaded hole 13 to fix the mounting frame 43 to the control box 1. The positioning of the mounting frame 43 is facilitated by the card connection, and then the mounting frame 43 is fixed to the control box 1 by bolts. In this embodiment, a single mounting block 11 is set on the middle one of the mounting frames 43 corresponding to the three knobs 3, and three mounting blocks 11 are set on the other two mounting frames 43.

When the end face gear 44 is installed, the elastic sheet 15 is driven to deform by abutting against the inclined surface of the elastic sheet 15, thereby facilitating the installation of the end face gear 44. After the end face gear 44 is installed, the elastic sheet 15 rebounds and abuts against the end face gear 44 under the action of elastic force. When the end face gear 44 needs to be removed, the elastic sheet 15 is pressed to make the elastic sheet 15 disengage from the abutment against the end face gear 44, thereby removing the end face gear 44 from the mounting column 14; the mounting column 14 is used for the installation of the end face gear 44 and also guides the rotation of the end face gear 44.
