A screw 62 is threadedly connected to the upper surface of the fixed plate 61. The screw 62 is rotatably connected to a limit plate 63 on one side close to the U-shaped frame 2. A scale 65 is fixedly connected to the upper surface of the limit plate 63. A pointer 66 is fixedly connected to the fixed plate 61 at a position corresponding to the scale 65. Before the ball screw needs to be cut off, the screw 62 on the fixing plate 61 is first rotated, and the screw 62 moves the limit plate 63 in the direction of the U-shaped frame 2. At this time, the staff judges the position of the limit plate 63 to the cutting knife 4 by the position of the scale 65 indicated by the pointer 66. When the limit plate 63 moves to the appropriate position, the staff stops rotating the screw 62, and then the staff moves the ball screw, and one end of the ball screw is against the limit plate 63, thereby achieving the effect of limiting the maximum displacement of the ball screw. At this time, the ball screw is fixed by the clamping assembly 5, and finally the cutting knife 4 is driven by the cylinder 3 to cut the ball screw. The adjusting device 6 is convenient for the staff to cut off a ball screw of a specific length, so as to avoid the situation where the staff repeatedly measures and marks the ball screw when they need to cut off more ball screws, thereby bringing convenience to the staff.

By providing the handle 64, the effect of facilitating the staff to rotate the screw 62 is achieved, which brings convenience to the staff. The end of the limit plate 63 away from the screw 62 is fixedly connected to a rubber pad 67, and the size of the rubber pad 67 is adapted to the size of the limit plate 63. By providing the rubber pad 67, the effect of protecting the limit plate 63 is achieved, and the limit plate 63 is prevented from being damaged when the ball screw contacts the limit plate 63. Two mutually symmetrical limit rods 68 are slidably penetrated on the surface of the fixed plate 61, and one end of the limit rod 68 is fixedly connected to the limit plate 63.
