when the device is used for cutting a workpiece 7 with a longer length, the workpiece 7 is pushed into the circular ring 3-5-6 in the above mode, then the conveyor belt 2 continues to drive the workpiece 7 to move, the rotary disc I4 rotates while the conveyor belt 2 moves to drive the belt 5 to move so as to drive the rotary disc II 3-3-1 to rotate, the rotary disc II 3-3-1 drives the ratchet I3-3-4 to rotate, the non-return pawl I3-3-5 and the non-return pawl II 3-3-6 are arranged in opposite directions, so that the ratchet I3-3-4 rotates to drive the ratchet II 3-3-7 to rotate through the non-return pawl II 3-3-6 so as to drive the gear I3-3-3 to rotate, and the gear I3-3-3 is matched with a plurality of lugs 3-4-7, the movable rod 3-4-4 is driven to move upwards, the distance between the lower arc-shaped block 3-4-2 and the upper arc-shaped block 3-4-3 is enlarged, a workpiece 7 can pass through smoothly, the motor I6 at the right end of the shell 3-1 is turned off after the preset length is reached, the rotating disc I4 stops rotating at the moment, the ratchet wheel I3-3-4 also stops rotating, the spring I3-4-5 pushes the movable rod 3-4-4 downwards, the convex block 3-4-7 on the movable rod 3-4-4 drives the gear I3-3-3 to rotate reversely, the gear I3-3-3 drives the ratchet wheel II 3-3-7 to rotate reversely, and the gear I3-3-3-3 does not block the movable rod 3-4-4 to move downwards, stopping moving until the upper arc-shaped block 3-4-3 is abutted against the workpiece 7, starting the motor II 3-6-1 and the motor III 3-6-7 in the above manner to enable the cutter 3-6-3 to cut the workpiece 7, starting the motor I6 at the right end of the shell 3-1 after cutting, enabling the motor I6 to rotate again to push the workpiece 7 to drive the finished product to move leftwards, simultaneously enabling the turntable I4 to rotate again to drive the turntable II 3-3-1 to rotate, further driving the gear I3-3-3 to rotate through the ratchet I3-3-4 and the ratchet II 3-3-7, finally driving the movable rod 3-4-4 to move upwards to enable the lower arc-shaped block 3-4-2 and the upper arc-shaped block 3-4-3 to be separated again, the finished product is conveniently separated, when the finished product moves into the rotary drum 3-2-3, the micro motor 3-2-1 drives the rotary drum 3-2-3 to rotate to the state shown in figure 6 through the teeth, the free end of the movable stop lever 3-2-7 faces downwards at the moment, the finished product pushes the movable stop lever 3-2-7 to rotate clockwise around the hinge, the movable stop lever 3-2-7 does not block the finished product from separating from the device, then the workpiece 7 moves to the position between the lower arc-shaped block 3-4-2 and the upper arc-shaped block 3-4-3, and then the cutting is continuously carried out according to the mode, and the reciprocating is carried out; the limiting device 3-2 has the effects that when the length of a workpiece 7 to be cut is long, the micro motor 3-2-1 drives the rotary drum 3-2-3 to rotate through the teeth, the rotary drum 3-2-3 rotates to drive the movable stop lever 3-2-7 to rotate until the free end faces upwards, at the moment, because the hinge connected to the movable stop lever 3-2-7 can only rotate 90 degrees, the baffle I3-2-5 is arranged in the rotating direction of the movable stop lever 3-2-7, the movable stop lever 3-2-7 is abutted against the baffle I3-2-5, the left end of the workpiece 7 is abutted against the movable stop lever 3-2-7, meanwhile, the friction force between the baffle I3-2-5 and the movable stop lever reduces the shaking of the left end of the workpiece 7, and when the long workpiece 7 is cut, the workpiece 7 is fixed by taking the circular ring 3-5-6 and the sliding block 3-5-8 as a first fixed point, the lower arc-shaped block 3-4-2 and the upper arc-shaped block 3-4-3 as a second fixed point and finally taking the movable stop lever 3-2-7 as a third fixed point, and the longer workpiece 7 is fixed in multiple points, so that the workpiece 7 can be effectively prevented from vibrating during cutting and further influencing the cutting effect. Sparks generated when a worker cuts the workpiece 7 during operation are blocked by the right side plate 3-1-3, so that the worker can be effectively prevented from being burnt by the sparks.
