The cross section 15 is provided with a mounting hole, and the movable joint 2 passes through the mounting hole to fix the two movable arms 1, so that the two movable arms 1 can move with the axis of the mounting hole as the axis. The movable joint 2 may be a socket, a bolt, a nail, a rivet, etc., and in the present utility model, the movable joint 2 is a hinge. During installation, the two movable arms 1 are installed in a mirror image mode, so that the two crossed sections 15 are connected in a cross mode, and after installation, the two movable arms 1 move in a scissor shape. When the two movable arms 1 are folded, a certain distance is reserved between the two second vertical sections 16, so that the lower part of the second vertical sections 16 is convenient for installing the pipeline clamp device 3.

Preferably, according to the lever principle, the length of the first vertical section 14 is longer than that of the second vertical section 16, so that the operation can be more labor-saving.

The upper portion of the movable arm 1 is provided with a handle 13 at the topmost end, so that the movable arm is convenient for a person to hold, and is used for increasing the friction force during holding, so that the movable arm is better in operation handfeel and can avoid slipping during operation. The handle 13 may be sleeved, glued or integrally formed.

As shown in fig. 3 and 4, the pipe clamp device 3 is movably mounted at the end of the second vertical section 16 by the movable joint 2. Which comprises a first clamping arm 31 and a second clamping arm 32. Specifically, the first clamping arm 31 and the second clamping arm 32 are mirror symmetrical and are provided with a bending portion 33 and a vertical portion 34, and the movable joint 2 is connected to the top of the first clamping arm 31 and the top of the second clamping arm 32. The upper end of the second clamping arm 32 is provided with a self-locking mechanism 4 for limiting the second clamping arm 32 along the extending direction of the second clamping arm 32.

The self-locking mechanism 4 comprises an elastic limit hook 41 and a self-locking block 42. The elastic limiting hook 41 is movably mounted on the second vertical section 16, the self-locking block 42 is fixedly mounted at the end of the second clamping arm 32, and when the self-locking block 42 moves, the elastic limiting hook 41 limits the self-locking block 42.

Specifically, the elastic limiting hook 41 includes an elastic member 41.1 and an arc hook 41.2, and in the present utility model, the elastic member 41.1 is a compression spring. The arc-shaped hook 41.2 is in a semi-arc shape, one end of the elastic piece 41.1 is fixed on the inner circle of the arc-shaped hook 41.2, the other end of the elastic piece 41.1 is fixed on the second vertical section 16, and the elastic piece 41.1 supports the arc-shaped hook 41.2 upwards.

Specifically, one end of the arc-shaped hook 41.2 is provided with a limiting tip 41.3, a round hole 41.4 is formed in a position, close to the limiting tip 41.3, of the arc-shaped hook 41.2, the arc-shaped hook 41.2 penetrates through the round hole 41.4 through a fixing column to be fixedly mounted on the movable arm 1, and the arc-shaped hook moves leftwards or rightwards with the axis of the round hole 41.4 as the center.

The upper end surface of the self-locking block 42 is arranged with a plurality of adjacent limit steps 42.1 which are arranged in the same direction, and the limit tip 41.3 is abutted against any one of the limit steps 42.1 to limit the self-locking block 42, thereby limiting the second clamping arm 32. A movable handle 42.2 for driving the self-locking block 42 to move is fixed on one side of the self-locking block 42. Specifically, the user pulls the movable handle 42.2 leftwards or rightwards, so as to drive the self-locking block 42 to move synchronously with the self-locking block, at this time, because the artificial pulling force is greater than the pulling force of the elastic piece 41.1 on the arc-shaped hook 41.2, the self-locking block 42 pushes the elastic limiting hook 41 to elastically move on the limiting step 42.1, and then the second clamping arm 32 is adjusted to be opened or closed with reference to the first clamping arm 31, so that the self-locking mechanism 4 is adjusted to adjust and control the opening or closing of the pipeline clamp device 3. Conversely, when the user stops pulling the movable handle 42.2, the elastic member 41.1 pulls the arc-shaped hook 41.2 to position the limiting tip 41.3 on the nearest limiting step 42.1, so as to play a role in adjusting and limiting the self-locking block 42.

Further, a clamping cavity 35 is provided between the first clamping arm 31 and the second clamping arm 32. A pipe clamp die head 36 is mounted on the inner wall of the vertical part 34 in the clamping cavity 35 through screws. The two pipe clamp dies 36 form a bracket shape, and the hot melt pipe 5 is placed between the two pipe clamp dies 36.

Preferably, the pipe clamp die 36 is made of soft materials, which can be used for adapting to the hot-melt pipe 5 and the hot-melt pipe fittings with different diameters, and the soft materials can strengthen the friction force between the hot-melt pipe 5 and the hot-melt pipe fittings, so as to better clamp and grip the hot-melt pipe 5 or the hot-melt pipe fittings.

As shown in fig. 5, the working principle is: when the hot-melt pipe 5 is in butt joint with a hot-melt pipe fitting, the two movable arms 1 are opened, the pipe clamp device 3 is adjusted and opened through the movable handle 42.2, one pipe clamp device 3 adjusts and clamps the end part of the hot-melt pipe 5, and the other pipe clamp device 3 adjusts and clamps the hot-melt pipe fitting. Manually pulling the movable arms 1 inwards brings the two movable arms 1 close to each other, so that the hot melt pipe 5 is aligned with the position of the hot melt pipe fitting and pushed into the hot melt pipe fitting.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof, and all technical solutions which may be obtained by logic analysis, reasoning or limited experiments based on the prior art according to the inventive concept should be within the scope of protection defined by the claims.
