If the output shaft of the speed reducer 10 is directly connected with the driven shaft of the actuating device through the universal joint 24, when the output shaft of the speed reducer 10 rotates at an equal angular speed, the angular speed of the driven shaft of the actuating device changes periodically in a range, so that additional dynamic load is caused, and the driven shaft of the actuating device is damaged. Because the connecting shaft 23 is connected with the driven shaft of the execution equipment and the connecting shaft 23 is connected with the output shaft of the speed reducer 10 through the universal coupling 24, even if additional dynamic load is generated, the additional dynamic load also acts on the connecting shaft 23, the driven shaft of the execution equipment is prevented from being damaged, and the use experience of products is improved. Since the connecting shaft 23 is relatively easy to replace, the difficulty in maintaining the product is reduced. Because the distances between the output shafts of the speed reducers 10 with different specifications and the base 11 are different, the first sliding blocks 17 and the second sliding blocks 18 drive the supporting plates 19 to move up and down through the first connecting rods 20 and the second connecting rods 21 so as to adjust the distance between the connecting shafts 23 and the base 11, so that the speed reducers 10 with different specifications are adapted, and the applicability of products is further improved.
