DETAILED DESCRIPTION

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, the new single-head sliding clamp comprises a clamp seat 1, a rotatable clamp head 2 is provided on the top of the clamp seat 1, a swivel joint 3 connected to the clamp head 2 is provided inside the clamp seat 1, a locking cap 4 is provided on the top of the clamp seat 1 and below the clamp head 2, a plane bearing 5 is cooperatedly provided between the swivel joint 3 and the locking cap 4, and the plane bearing 5 also plays a wear-resistant role. Under the action of the plane bearing 5, the rotating clamp head 2 can adjust the circumferential position of the clamp head 2 at any time, and is suitable for various working conditions.

[0018] The clamp head 2 is composed of a sliding clamp guide rail 6, a sliding clamp head 7 mounted on the sliding clamp, and a piston 8 arranged inside the sliding clamp guide rail 6. The sliding clamp guide rail 6 is provided with a movable clamp 9 that reciprocates along its surface and a fixed clamp 10 fixed to the sliding clamp guide rail 6. The tops of the movable clamp 9 and the fixed clamp 10 are both provided with a slot 11 for the copper pipe to be clamped. A spring 12 is also provided in the sliding clamp guide rail 6, and one end of the spring 12 abuts against the piston 8. The inner wall of the sliding clamp guide rail 6 is relatively A radially outwardly protruding limit platform 13 is provided at the position corresponding to the fixed clamp 10, and the other end of the spring 12 rests on the limit platform 13. Copper tubes to be crimped are respectively provided on the movable clamp 9 and the fixed clamp 10, and brass is provided on the copper tubes. Currently, in order to butt and press-fit the two brasses, the movable clamp 9 is driven by the piston 8 to move linearly along the sliding clamp guide rail 6, and the spring 12 is compressed. At the same time, the brass on both sides are butt-jointed and a press-fitting action is generated. After the press-fitting is completed, the spring 12 automatically resets and the movable clamp 9 resets.

[0019] Preferably, a waist-shaped groove 14 is provided on the sliding clamp guide rail 6, the movable clamp 9 is connected to the piston 8 through a pull pin 15, and the pull pin 15 passes through the waist-shaped groove 14 and is used to drive the movable clamp 9 to move, and the fixed clamp 10 is fixedly connected to the limit platform 13 through a pull pin 2 16.
