[0026] The specific implementation method of the active end of the driving structure is as follows:

[0027] according to Figure 1 The structure shown assembles the active end of the drive structure. First, the first bearing 3 and the first gear shaft 12 are installed into the front support housing 13. Then, the second bearing 4, the second gear shaft 5, and the first gear 11 are installed into the front support housing 13. Next, the third bearing 6, the third gear shaft 7, and the second gear 8 are installed into the front support housing 13. Each gear shaft is fixed with screws.

Then fix the adjusted drive shafts to the support housing to complete the assembly of the drive structure drive shaft system.

[0033] Step 3: Install the pulleys on the first-stage drive shafts of the driving and driven ends respectively, adjust the position of the first-stage drive shaft of the driving end to ensure that the double gear backlash elimination structure is effective, and then use the tensioning mechanism to fix the position of the pulleys and the first-stage drive shaft.

[0034] Fourth step; drive structure operation, motor through the belt power transmission to the large pulley drive first level transmission shaft rotation, and then by the gear power level by level transmission to the swing body on it to rotate.
