The two ends of the supporting bottom rod 7 are respectively slidably sleeved on the two guide rods 5. The guiding effect of the guide rods 5 prevents the electric push rod 6 from causing the supporting bottom rod 7 to move.

[0025] The lifting assembly includes a notch 8 formed on one side of the supporting bottom bar 7, an adjusting bolt 17 is screwed to the top of the notch 8, the upper end of the adjusting bolt 17 extends to the top of the supporting bottom bar 7 and is rotatably connected to a U-shaped supporting bar 10 through a bearing;

[0026] The clamping assembly includes a U-shaped holding rod 14 and two support blocks 11 fixed at both ends of the supporting bottom rod 7. The bottom ends of the vertical sections on both sides of the U-shaped holding rod 14 are provided with extension blocks 13, and the two extension blocks 13 are respectively connected to the two support blocks 11 through fixing bolts 12;

Use a wrench to turn the adjusting bolt 17 to adjust the height of the U-shaped support rod 10 so that the output end of the reducer is aligned with the end of the transmission rod 3. Then use the fixing bolts 12 to respectively connect the extension blocks 13 of the two U-shaped holding rods 14 with the support block 11 to achieve the installation and fixation of the reducer. Then connect the end of the transmission rod 3 to the output end of the reducer.
