[0038] Specifically, the bending device is changed from an overall sliding structure to a structure in which only the bending mechanism 200 is slidably installed on the bending mounting seat 100. At the same time, the driving part is independently installed on the bending mounting seat 100, thereby improving the structural strength of the bending device and the stability of its mobile operation, and reducing its activity during operation, thereby reducing the impact on the bending effect; in addition, the moving part 210 can be pivotally mounted through bearings and shafts; wherein, the reciprocating power mechanism 400 can refer to the prior art and is not described here; wherein, the passive gear 321 or tooth structure of the transmission assembly 320 is mostly arranged on the moving part 210, and can also be arranged on the bending part 220, such as a gear or tooth structure is arranged on the outer peripheral wall of the bending seat of the bending part 220.
