After moving to the side of the pipe, the wheels no longer move by locking. The two wheels 2 are respectively located at the front and rear ends of the vehicle plate 1. A connecting shaft 3 is installed on one side of the top of the vehicle plate 1 through a bearing seat, and a cutting knife 4 is installed at the front end of the connecting shaft 3. The pipe can be controlled to rotate by existing equipment. A transmission motor 5 is set on the other side of the top of the vehicle plate 1. When not in use, the gravity of the transmission motor 5 automatically presses the other side of the vehicle plate downward, that is, the vehicle plate 1 is The wheel is folded with the center of the circle as the center, and the rear end of the connecting shaft 3 is equipped with a matching pulley. The rear end of the output shaft of the transmission motor 5 is installed with a driving pulley. The driving pulley and the matching pulley are connected by a connecting belt.

Several moving wheels are installed at the bottom end of the gravity block 7. A screw rod 8 is provided on the top of the gravity block 7. The screw rod 8 passes through the through groove. A nut 9 is provided on the screw thread. The diameter of the nut 9 is greater than the width of the through groove. A limited rotation mechanism is provided below the nut 9. , the limited rotation mechanism limits the nut 9 to rotate synchronously with the screw 8, and a connecting transmission mechanism is provided on the top of one side of the gravity block 7. The connecting transmission mechanism can control the rotation of the screw 8. A large gear 10 and a small gear 11 are provided on one side of the gravity block 7. The large gear 10 and the small gear 11 are both connected to the connecting transmission mechanism. A rotating rod 12 is installed at one end of the connecting shaft of the large gear 10 and the connecting shaft of the small gear 11. The rotating small gear 11 or the large gear controls the screw 8 to rotate through the connecting transmission mechanism. The nut 9 moves downward and presses under the limitation of the limited rotation mechanism. The plate 6 contacts and drives one side of the pressure plate 6 to move downward. At this time, the other side of the car plate 2 starts to move upward. Through the gear ratio of the small gear 11 and the large gear 10, when the small gear is rotated, the speed of the screw 8 is slow, and the speed at which the nut presses the pressure plate downward is slow. This is suitable for the cutting feed process. After the cutting is completed, the large gear is rotated to move the nut 9 upward quickly. The other side of the pressure plate falls downward under the action of gravity, and one side of the pressure plate moves upward. The cutting knife is away from the workpiece. During the operation, the worker can sit on a chair and control the rotation of the rotating rod on one side of the gravity block.Push the car plate 1 and the gravity block 7 to move so that the pipe is located under the cutting knife 4. At this time, the transmission motor 5 presses the other side of the car plate 1 downward, and one side of the car plate 1 is in a tilted state. When the worker sits on the chair, he operates the large gear 10 and controls the screw 8 to rotate through the connecting transmission mechanism. Under the limitation of the limited rotation mechanism, the nut 9 moves downward and contacts the top surface of the pressure plate 6, pressing the pressure plate 6 downward. Under the gear ratio of the large gear 10, the nut 9 moves downward quickly, driving the cutting knife 4 to move downward quickly. When the cutting knife 4 is about to approach the pipe fitting, this When the small gear 11 is operated, that is, the rotating rod 12 on the small gear 11 is rotated, and the cutting knife 4 is slowly fed downward through the gear ratio of the small gear 11. After the feeding is completed, the nut 9 and the screw 8 have a self-locking function, and the nut 9 always presses the pressure plate 6 downward. The pipe rotates under the control of the existing equipment, and the pipe is cut by the cutting knife 4. After the cutting is completed, the rotating rod 12 on the large gear 10 is rotated to move the nut 9 upward. The nut no longer presses the pressure plate, and the other side of the car plate 1 is pressed downward by the weight of the transmission motor 5. The pressure plate 6 moves upward and the cutting is completed. The knife is away from the pipe. Through this step, the worker can perform the cutting operation on a chair. Moreover, during the cutting operation, the worker has a certain distance from the cutting knife to avoid sparks or other materials from contacting the worker. When the worker needs to cut quickly while standing, the pipe is located under the cutting knife 4. The worker presses the pressure plate 6 downward with his hand, and the pressure plate 6 moves downward. The cutting knife 4 moves downward to contact the pipe and cuts the pipe. After the cutting is completed, the force is released. Under the weight of the transmission motor 5, the pressure plate 6 tilts upward, and the cutting knife is away from the pipe. The present invention can perform different operations as needed. When sitting down to operate the rotating rod, the worker does not need to press the pressure plate all the time, saving physical strength. In addition, the downward movement of the nut 9 can control the different feed depths of the cutting knife and adjust it according to the thickness of the pipe. When standing, pressing the pressure plate downward can quickly drive the cutting knife 4 to move downward for fast cutting. For pipes that are long and inconvenient to move, the wheel 2 and the moving wheel can be used to move the car plate 1 and the gravity block 7 to the side of the pipe. It is more convenient to move and the cutting position is no longer limited to a certain place.

The two rods 13 are located on either side of the nuts 9 and can be inserted into the through-grooves. After the rods 13 are inserted into the through-grooves, the bottom end of the nuts 9 contacts the top end of the pressure plate 6. The downward movement of the nuts 9 drives one side of the pressure plate 6 downward, controlling the downward feed of the cutting blade. When the nuts 9 are no longer needed to control the downward movement of the pressure plate 6, the cutting blade feed depth can also be controlled by manually pressing the pressure plate 6 downward.

[0014] Furthermore, the connecting transmission mechanism described in this embodiment includes a vertical rod group installed on the top of the gravity block 7, and the first bevel gear 15 is installed on the bearing at the top of the vertical rod group.

A matching gear 19 is installed on the other end of the connecting shaft 17. The matching gear 19 is located between the large gear and the small gear, and is meshed with the large gear and the small gear. The long groove 14 will not affect the threaded fit between the screw and the nut. The outer periphery of the connecting shaft 17 is connected to the inner wall of the inner ring of the bearing, and the outer wall of the outer ring of the bearing is connected to the top of the support rod 16. When the large gear and the small gear rotate, the matching gear 19 can be controlled to rotate. Through the transmission of the connecting shaft 17, the second bevel gear 18 is driven to rotate, and the first bevel gear 15 is driven to rotate. Through the fit of the insert block and the long groove 14, the screw 8 is driven to rotate, and the nut 9 is controlled to move up and down.
