[0025] The mounting plate 1 in this embodiment is welded by two trapezoidal side panels 13 and a rectangular base plate 12. The base plate 12 is provided with a plurality of mounting screw holes 11 through the center. The mounting screw holes 11 are used to connect and fix with the body of the device. An adjustment screw hole is provided through the center of the base plate 12, and the lower bottom edge of the side panel 13 is welded to the base plate 12.

[0026] In this embodiment, a semi-long groove and a rectangular groove are provided at the upper and lower bottoms of the side plate 13, and a through hole 14 is provided through the connecting portion between the two grooves. One end of the semi-long groove is in a semicircular transition form, and a limit block is provided on the other end.
