The limiting ring 18 is located in the spring groove 17 near the positioning hole 6, and the compression spring 19 is reserved with a compression amount when installed.

[0025] The setting of the compression spring 19 can provide a rebound force for the positioning rod 5 to be inserted into the positioning hole 6. At the same time, the compression spring 19 has a reserved compression amount during installation to continuously generate pressure on the limit ring 18, thereby increasing the stability of the positioning rod 5 inserted into the positioning hole 6.

[0026] The fixed seat 3 is provided with a motor 13, and the output shaft of the motor 13 is fixedly connected with a bidirectional screw rod 11 which is rotatably arranged in the fixed seat 3; the bidirectional screw rod 11 is threadedly connected with two oppositely arranged moving plates 12, and the moving plates 12 are fixedly connected with the sliding plate 16. The slide groove 14 is square, and the sliding plate 16 is a square corresponding to the slide groove 14, and the sliding plate 16 and the inner wall of the slide groove 14 are in contact with each other.

[0027] The matching arrangement of the square slide groove 14 and the square sliding plate 16 can limit the rotation of the moving plate 12 , thereby converting the rotation of the bidirectional screw rod 11 into the movement of the moving plate 12 and transmitting the movement to the sliding plate 16 .

[0028] The positioning holes 6 are distributed at equal angles in a circle on the rotating block 8, and the fixing holes 10 are also distributed at equal angles in a circle on the rotating block 8, and the positions of the positioning holes 6 and the fixing holes 10 correspond one to one.

The one-to-one correspondence between the positioning holes 6 and the fixing holes 10 can ensure the consistency of positioning and fixing of the rotating block 8.

[0029] Principle of the utility model

[0030] When the installation direction of the reducer body 4 is adjusted, the motor 13 is started to move the two sliding plates 16 in a direction away from each other, and the fixing rod 15 is disengaged from the fixing hole 10; the positioning rod 5 is pulled upward to disengage the positioning rod 5 from the positioning hole 6, and the limit ring 18 compresses the compression spring 19; at this time, the reducer body 4 can be directly rotated, and after adjusting the direction of the reducer body 4, the positioning hole 6 is aligned with the spring groove 17, and the positioning rod 5 is loosened. Under the action of the rebound force of the compression spring 19, the positioning rod 5 is inserted into the positioning hole 6 to position and preliminarily fix the rotating block 8; the motor 13 is reversed, the two sliding plates 16 move in a direction close to each other, and the fixing rod 15 is inserted into the fixing hole 10 to realize the rapid fixation of the rotating block 8. Therefore, when the installation direction of the reducer body 4 is adjusted, the present application does not need to disassemble and install the mounting seat 1 or the fixing seat 3. By setting the rotating rotating block 8 in the fixing seat 3, the direction of the reducer can be quickly adjusted and the quick installation and fixation after adjustment can be realized, which can solve the problem that the prior art is troublesome in adjusting the installation direction of the reducer.
