Several electronic components are stuck into the placement slot 2, and their pins are inserted into the box body 1 through the jack 3. The cylinder 5 is started, and the cylinder 5 drives the cutting knife 6 to move forward to cut the pins and insert the pins into the rectangular slot 83. After the cutting knife 6 is cut, the rotating shaft 81 is rotated back and forth, driving the rectangular plate 82 to swing back and forth, and then the rectangular plate 82 drives several pins to swing back and forth, which can break off the pins that are not completely cut off, without multiple cutting, thereby avoiding the situation that some pins are difficult to completely disconnect when cutting because the pins are made of metal, and repeated cutting is required multiple times, which increases the loss of the cutting knife 6. A connecting block 84 is fixedly connected to one rotating shaft 81, connecting The cam 86 is moved in a direction of rotation so that the cam 86 can be moved in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam 86 can move in a direction of rotation so that the cam
[0029] Reference Figure 1 and Figure 4, an adjustment structure 9 is provided on the box body 1, and the adjustment structure 9 is mainly composed of two sliding grooves 91. The two sliding grooves 91 are respectively opened on both sides of the box body 1. A sliding block 92 is slidably connected in the sliding groove 91. The sliding block 92 is fixedly connected to the equipment plate 4. The height of the equipment plate 4 can be adjusted by sliding the two sliding blocks 92, thereby changing the height of the cutting knife 6 to adapt to different cutting lengths, thereby improving the applicability of the equipment. A rack 93 is fixedly connected to a sliding block 92, and a gear 94 is meshed and connected to the rack 93. A fixed plate 95 is fixedly connected to one side of the box body 1, and a second motor 96 is fixedly connected to the fixed plate 95. The output shaft of the second motor 96 is fixedly connected to the gear 94. When the second motor 96 is started, the output shaft of the second motor 96 drives the gear 94 to rotate, thereby driving the rack 93 to slide, further driving the sliding When the rack 93 is in the correct position, the limit rod 98 can be inserted between the two limit blocks 97 to limit the rack 93 and prevent the rack 93 from sliding down under the action of gravity. A spring 99 is sleeved on the limit rod 98, one end of which is fixedly connected to the fixed plate 95, and the other end of the spring 99 is fixedly connected to the limit rod 98. When the rack 93 slides upward, the contact surface between the limit block 97 and the limit rod 98 is an inclined surface, which will push the limit rod 98 to slide to the right. At this time, the spring 99 is in a stretched state, so when the limit rod 98 contacts the gap between the two limit blocks 97, the limit rod 98 slides to the left under the action of the rebound force of the spring 99, making the operation more convenient.

After the cutting knife 6 has finished cutting, the rotating shaft 81 is rotated back and forth, driving the rectangular plate 82 to swing back and forth, thereby causing the rectangular plate 82 to drive several pins to swing back and forth, so that the pins that have not been completely cut off can be broken off without multiple cutting, thereby avoiding the situation that some pins are difficult to completely break off when cutting because the pins are made of metal and need to be cut repeatedly, which increases the wear of the cutting knife 6. Rotate the turntable 87, and the turntable 87 drives the slide bar 86 to rotate. Since the slide bar 86 slides in the slide groove 85, it drives the connecting block 84 to swing back and forth, further driving the rectangular plate 82 to swing, making the operation more convenient. Start the first motor 89, and the output shaft of the first motor 89 drives the turntable 87 to rotate, further improving the convenience of operation. The cut pins fall to the guide through the rectangular slot 83. The pins are then discharged from the box 1 through the discharge chute 811 along the guide plate 810, which is convenient for collecting and processing the pins. The height of the equipment plate 4 can be adjusted by sliding the two sliding blocks 92, thereby changing the height of the cutting knife 6 to adapt to different cutting lengths, thereby improving the applicability of the equipment. The second motor 96 is started, and the output shaft of the second motor 96 drives the gear 94 to rotate, thereby driving the rack 93 to slide, and further driving the sliding block 92 to slide, making the operation more convenient. When the rack 93 After the position is adjusted, the limit rod 98 can be slid and inserted between the two limit blocks 97 to limit the rack 93 and prevent the rack 93 from sliding down under the action of gravity. When the rack 93 slides upward, the contact surface between the limit block 97 and the limit rod 98 is an inclined surface, which will push the limit rod 98 to slide to the right. At this time, the spring 99 is in a stretched state. Therefore, when the limit rod 98 contacts the gap between the two limit blocks 97, the limit rod 98 slides to the left under the action of the rebound force of the spring 99, making the operation more convenient.
