[0027] Specifically, a driving groove 8 is provided on the push block 7, and the driving rod 9 is slidingly connected to the push block 7 through the driving groove 8. A fixed shaft 10 is provided on the mounting block 5, and the driving rod 9 is rotatably connected to the mounting block 5 through the fixed shaft 10.

[0028] Specifically, a tensioning groove 18 is provided on the inner wall of the protective box 12, a tensioning spring 21 is provided in the tensioning groove 18, a tensioning wheel 19 is slidably installed on the tensioning groove 18 and is connected to the tensioning spring 21, and a support wheel 22 is also rotatably provided on the inner wall of the protective box 12 between the two sprockets 17.

[0029] Specifically, the transmission assembly includes a transmission shaft 15 rotatably set on the slider 14, one end of the transmission shaft 15 is fixedly connected to the sprocket 17, and a fixing bar 27 is provided on the side wall of the other end of the transmission shaft 15. The transmission shaft 15 is also provided with a connecting pipe 16, and a connecting groove 26 is provided on the inner wall of the connecting pipe 16. The connecting groove 26 matches the fixing bar 27, and a fixing bolt 28 is also provided on the connecting pipe 16.

[0030] Specifically, a blocking rod 4 is fixedly provided on the slide 3 on the side close to the push block 7 .

[0031] Specifically, a limiting block 11 is fixedly provided on the mounting plate 1 , and the push block 7 is located between the slide plate 3 and the limiting block 11 .

[0032] Specifically, a box door 23 is hingedly mounted on the protection box 12 , a plurality of support legs 24 are fixedly mounted on the bottom of the mounting plate 1 , and supporting feet 25 are fixedly mounted on the bottom of both the protection box 12 and the support legs 24 .

[0033] The working process of this embodiment is as follows: when in use, first drag the slide 3 out from between the two mounting blocks 5 along the slide groove 2, then place the reducer on the slide 3, ensure that the output shaft of the reducer is located on one side of the protective box 12, and make the mounting seat of the reducer fit with the block rod 4, then push the slide 3 to slide between the two mounting blocks 5, and continue to push the slide 3, and push the push block 7 to move through the slide 3. When the push block 7 moves, one end of the drive rod 9 will slide along the drive groove 8. At this time, the other end of the drive rod 9 will push the pressure plate 6 to move toward the slide groove 2, and the two pressure plates 6 will be stuck on the mounting seat of the reducer after relative movement to fix the reducer.

[0034] Then slide the slider 14 along the adjustment groove 13. When the connecting tube 16 on the slider 14 is aligned with the output shaft of the reducer, pull the connecting tube 16 so that the connecting tube 16 is sleeved on the output shaft of the reducer. The fixing strip 27 on the inner wall of the connecting tube 16 is inserted into the keyway on the output shaft of the reducer, and then fixed with the fixing bolt 28 to realize the connection between the output shaft of the reducer and the sprocket 17.

[0035] When the two reducers are connected to the sprocket 17, the tensioning wheel 19 slides along the tensioning groove 18 to compress the tensioning spring 21. After the connection is completed, the elastic force of the tensioning spring 21 enables the tensioning wheel 19 to tighten the chain 20.

[0036] Since the reducer can convert high-speed and low-torque input into low-speed and high-torque output during forward transmission, that is, the power required to drive the reducer to work through the input shaft of the reducer is relatively small, while the power required to drive the reducer to work through the output shaft of the reducer is relatively large. In this embodiment, when the two reducers are towed together, the output shafts of the two reducers are connected together. The output shaft of the driven reducer is now the input shaft, and it will encounter greater resistance during input to drive the gears in the reducer to rotate. Therefore, when Figure 3 When the left side is the driving reducer and the right side is the driven reducer, when the sprocket 17 on the left rotates counterclockwise, the east-west reducer on the right will be pulled to the left by the chain 20, and at the same time, the driving reducer on the left will also be pulled to the right, so the two reducers will tend to move relative to each other, thereby pushing the two push blocks 7 to further fix the reducers; the support legs 24 and the support feet 25 can provide stable support for the equipment.

[0037] The protective box 12 can protect the sprocket 17 and the chain 20 to avoid mechanical damage to the staff, while the box door 23 is convenient for the staff to carry out inspection and maintenance.

However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
