[0002] Copper pipe is also called red copper pipe. It is a kind of non-ferrous metal pipe, which is a pressed and drawn seamless pipe. Copper pipe has good electrical and thermal conductivity. It is the main material for the conductive accessories and heat dissipation accessories of electronic products. It has become the first choice of modern contractors for the installation of water pipes, heating and cooling pipes in all residential commercial houses. Copper pipe has strong corrosion resistance, is not easy to oxidize, and is not easy to react chemically with some liquid substances. It is easy to bend and shape.

[0003] Copper tubes are often clamped during their production process. The commonly used clamping device requires pushing the copper tube to the clamping part of the clamping device and then pulling it out after processing. Because the copper tube itself is relatively long, a larger operating space is required for pushing and pulling operations, making it inconvenient to take. Utility Model Content

[0006] By adopting the above technical solution, the copper tube can be directly taken out without pulling the copper tube out of the device, which makes it convenient to take out the copper tube and reduces space occupation.

[0007] A handle 1 is installed at the end of the bidirectional screw rod 1, and a handle 2 is installed at the end of the bidirectional screw rod 2.

[0008] By adopting the above technical solution, the handle 1 and the handle 2 can be rotated to adjust the positions of the limiting part 1 and the limiting part 2 respectively.

[0010] By adopting the above technical solution, the pressure plate applies pressure to one end of the guide plate, thereby limiting the upward freedom of the two ends of the guide plate.

[0011] The structures of the limiting part 1 and the limiting part 2 are consistent, and grooves are provided on the upper sides of the ends of the two groups of limiting parts 1 that are close to each other and on the lower sides of the ends of the two groups of limiting parts 2 that are close to each other.

[0022] There is a distance between the guide plate 2 13 and the fixed frame 14 so that the guide plate 2 13 can rotate normally at the output end of the electric cylinder 8 through the fixed seat 9; two guide rails 2 are provided, and the slide seat 3 can stably slide along the guide rails 2 on the workbench 1, and the fixed frame 14 is arranged in an L-shaped structure, and the adjustment part 15 is rotatably installed on the top end of the fixed frame 14, and the pressure plate 16 at the bottom of the fixed frame 14 can be abutted against the guide plate 2 13 without being affected by the fixed frame 14 in its rotation.

[0023] A handle 15 is installed at the end of the bidirectional screw rod 16, and a handle 2 10 is installed at the end of the bidirectional screw rod 11; the bidirectional screw rod 16 is arranged through the fixed frame 14, one end of which is rotatably installed on one side of the electric cylinder 8 through a rotating shaft, and the other end is fixedly connected to the handle 15, and the guide plate 2 13 is an L-shaped structure as a whole, one end of the bidirectional screw rod 2 11 passes through the fixed seat 9, and the other end is rotatably connected to the shorter end of the guide plate 2 13, the guide plate 14, the bidirectional screw rod 16, the bidirectional screw rod 2 11 and the guide plate 2 13 are all arranged in a horizontal state, the guide plate 14 and the bidirectional screw rod 16 are arranged parallel to each other, and the bidirectional screw rod 2 11 and the guide plate 2 13 are arranged parallel to each other.

An adjusting part 15 is also rotatably installed on the fixing frame 14, and a pressing plate 16 is rotatably installed at the bottom of the adjusting part 15. When the pressing plate 16 moves to the top of the limiting part 1 7, the adjusting part 15 can be rotated to push the pressing plate 16 to move downward, and the upward freedom of one end of the guide plate 2 13 is limited by the pressing plate 16, so that the copper tube can be stably clamped by the two limiting parts 1 7 and the two limiting parts 2 12.

At this time, the adjustment part 15 can be rotated to push the pressure plate 16 downward to contact the guide plate 2 13, and the upward freedom of one end of the guide plate 2 13 is limited. Then, the handle 2 10 is rotated to drive the two groups of limit parts 2 12 to make opposite movements along the guide plate 2 13 through the bidirectional screw rod 2 11, and the distance between the two groups of limit parts 2 12 is adjusted, so that the copper tube can be clamped;

[0028] The device can directly take the copper pipe without pulling the copper pipe out of the device, which makes it convenient to take the copper pipe and reduces space occupation.

[0029] The device can also push the slide 3 to adjust the two sets of positioning mechanisms on the workbench 1 as needed, so as to better clamp and position the copper tube.
