The lower end of the controller housing 1 and the positioning groove The inner sides of 71 are adapted to each other, and the lower end of the support plate 7 is fixedly connected to the upper end of the reducer body 2. Four support plates 7 are symmetrically arranged on the left and right. Fixed plates 8 are arranged on the front and rear sides of the controller housing 1. Two fixed plates 8 are symmetrically arranged on the front and rear sides and are fixedly connected to the upper end of the reducer body 2. The fixed plates 8 and the front and rear sides of the controller housing 1 are adapted to each other. The surfaces of the fixed plates 8 are provided with engaging grooves 81, and the engaging blocks 6 are engaged with the engaging grooves 81. After the reducer body 2 is installed in a suitable position, the controller housing 1 is placed between the two fixing plates 8 and the controller housing 1 is pressed down until it fits with the inner side of the positioning groove 71.
