[0026] Embodiment 1

[0027] As Figures 1 - 3 shown, the arc starting device in this embodiment is mainly used for arc starting and bending processing of relatively thin metal plates, and mainly consists of a workbench 10, a clamping part arranged on the workbench 10, and an arc starting part rotatably arranged on one side of the clamping part. Through the cooperation of the clamping part and the arc starting part, the plates inside the two are subjected to arc starting processing.

[0028] Specifically, the arc starting part includes an arc starting plate 40 and a holding assembly 50. The arc starting plate 40 is rotatably connected to the workbench 10 through a hinge. The plate extends to the arc starting plate 40. The holding assembly 50 is connected to the arc starting plate 40, and the holding assembly 50 is for human hand holding use.

[0029] Among them, the holding assembly 50 includes two support rods 51. The support rods 51 are connected to the arc starting plate 40. The ends of the support rods 51 are provided with soft sheaths 52 made of rubber material to protect the hands, and a reinforcing rod 53 is arranged between the two support rods 51 to enhance the strength.

[0030] And, the clamping part includes a clamping plate 20 and locking assemblies 30 arranged on both sides of the clamping plate 20. The plate is clamped between the clamping plate 20 and the workbench 10. The locking assembly 30 includes a first locking piece 31 and a second locking piece. The second locking piece is rotatably sleeved on the first locking piece 31, and the second locking piece is used to press on the upper end of the clamping plate 20.

[0031] Combined with Figure 4 shown, among them, the clamping plate 20 includes two oppositely arranged support plates 21. There is an included angle between the two support plates 21, and a downwardly concave locking surface 23 is provided at each end of the clamping plate 20 in the length direction. The locking surface 23 abuts against the second locking piece. At the same time, in order to reduce the operation effort, a plurality of weight reduction holes 211 are provided on the support plate 21, and the weight reduction holes 211 are arranged in parallel.

[0032] Moreover, a handle body 22 is provided above the clamping plate 20. The handle body 22 includes two connecting rods 221 and a handle rod 222. The handle rod 222 is disposed between the two connecting rods 221 and has a spacing from the clamping plate 20. The connecting rods 221 are connected to the clamping plate 20, and the clamping plate 20 can be conveniently lifted and placed by holding the handle body 22.

[0033] Combined with Figure 5 As shown, the first locking member 31 is vertically disposed on the workbench 10. The second locking member includes a main sleeve body 32. The main sleeve body 32 is sleeved on the first locking member 31 and is in threaded cooperation with the first locking member 31. A retaining edge 33 is disposed around the main sleeve body 32. The lower end surface of the retaining edge 33 is horizontally disposed and is parallel to the locking surface 23. The retaining edge 33 is used to abut against the locking surface 23, and at least one force applying rod body 34 is inclinedly disposed on the side wall of the main sleeve body 32. That is, the first locking member 31 and the second locking member generally form a connection structure of a screw and a nut, and the main sleeve body 32 can be conveniently rotated by the force applying rod body 34.

[0034] When the present utility model is in use, the plate to be processed is placed on the workbench 10, the position where the arc needs to be started is pushed into the arc plate 40, and then the clamping plate 20 is placed on the upper end of the plate. The second locking member is rotated until it abuts against the clamping plate 20 to complete the locking of the plate. Subsequently, the lifting and holding assembly 50 is rotated, and the plate can be subjected to arc processing. By selecting the rotation and lifting angle, the change of the processing radian can be realized.

[0035] All the ways described herein can be carried out in any suitable order. Any and all examples used, or the exemplary language provided herein (such as "for example") are only used to better illustrate the present utility model and are not a limitation on the scope of the present utility model, unless otherwise claimed.
