[0040] In some embodiments, Figure 3 As shown, the driving assembly 12 includes a driving motor 121, a first ball screw 122 and a slide 123. Along the length direction of the bottom plate 112 (i.e., the length direction of the housing 11), the driving motor 121 can be fixed to one end of the bottom plate 112, one end of the first ball screw 122 can be connected to the output end of the driving motor 121, and the other end of the bottom plate 112 can be provided with a bearing seat 124, the other end of the first ball screw 122 can be rotatably connected to the bearing seat 124, and the driving motor 121 can drive the first ball screw 122 to rotate in the bearing seat 124. The slide 123 can be rotatably connected to the first ball screw 122, so that the slide 123 can be driven to move on the first ball screw 122 when the first ball screw 122 rotates.

The length direction of the strip-shaped hole 114 may be consistent with the length direction of the top plate 111 (i.e., consistent with the length direction of the housing 11). The stop finger body 13 includes a stop finger member 131 and a connecting member 132 connected to the stop finger member 131. The stop finger member 131 may be located outside the accommodation space.

The second ball screw 23 can be fixed to the second bracket 22, and the stop finger mechanism 10 can be arranged on the first bracket 21. The first bracket 21 is rotatably connected to the second ball screw 23, so that when the second ball screw 23 rotates, it can drive the first bracket 21 to move on the second ball screw 23 to adjust the position of the stop finger device 100 in the up and down directions of the bending machine 1000.

[0046] In some embodiments, as Figure 2 shown, a handwheel 25 may be provided at one end of the second ball screw 23, and the second ball screw 23 can be rotated by the handwheel 25, which is convenient for operation.
