A section of the right end of the two-way screw 4 is set as a polished rod. , the polished rod part of the two-way screw 4 extends into the right side wall of the box 1 and is rotationally connected to the right side wall of the box 1 through the bearing. The middle of the two-way screw 4 is set as a polished rod, and the two sides of the middle polished rod are The threads are arranged in opposite directions, and a threaded sleeve 5 is provided on each of the opposite threads. The top of the threaded sleeve 5 is fixedly connected to a slider 6. The slider 6 passes through the chute on the top wall of the box 1 and extends to the top of the chute. And it is slidingly connected with the chute. Start the motor 3. The motor 3 drives the two-way screw 4 to rotate through the motor shaft. Since the threads on both sides of the middle polished rod on the two-way screw 4 are opposite, the thread sleeve 5 on the two-way screw 4 is will rotate relative to each other. Since the threaded sleeve 5 is fixedly connected to the slider 6, and the slider 6 passes through the chute and is slidingly connected, the threaded sleeve 5 can only move on the two-way screw rod 4 and cannot drive the slider 6 to rotate. A fixed shaft 8 is fixedly installed on the top of the slider 6, and a sleeve 16 is installed on the end of the fixed shaft 8. The sleeve 16 is rotationally connected to the fixed shaft 8 through a bearing, and the outer wall of the sleeve 16 is fixedly installed with a shock absorber. 17, the end of the shock absorber 17 is fixed with a clamping plate 18, one side of the clamping plate 18 is set as an arc surface, and the other side of the arc surface is set as a straight surface, the end of the shock absorber 17 It is connected to the straight surface of the clamping plate 18. The shock absorber 17 is surrounded by a spring 20. One end of the spring 20 is fixedly installed on the outer wall of the sleeve 16, and the other end is connected to the straight surface of the clamping plate 18. , a rubber pad 19 is installed in the arc surface of the clamped plate 18. The rubber pad 19 can increase the friction with the pipe and improve the clamping of the pipe. The relative movement of the clamping plate 18 can be controlled by the forward rotation of the motor 3. The pipes can be clamped, and the motor 3 can control the relative distance between the clamping plates 18 to facilitate clamping of pipes of different diameters. When clamping is not required, the motor 3 only needs to be reversed to move the clamping plates 18 in the opposite direction. That is, the pipe can be taken out. The shock absorber 17 and the spring 20 can play a shock-absorbing effect on the clamping plate 18 when clamping the pipe, preventing the pipe from colliding with the clamping plate 18 and causing damage to the pipe. The sleeve 16 Threaded holes are provided on the top, and fastening bolts 15 are provided in the threaded holes. When it is necessary to clamp pipes at different angles, first loosen the fastening bolts 15 and rotate the sleeve 16. The sleeve 16 is fixed on the fixed shaft 8 through the bearing. Rotate, the sleeve 16 drives the clamping plate 18 to rotate through the shock absorber 17. When the clamping plate 18 rotates to the angle we need, tighten the fastening bolt 15, and the end of the fastening bolt 15 is against the fixed shaft 8. In this way, the sleeve 16 and the fixed shaft 8 are firmly combined without sliding. By rotating the sleeve 16, pipes at different angles can be clamped, thereby increasing the range of use of the device. A housing 7 is provided on the top of the box 1.
