[0023] Specifically, the support assembly 7 includes an arc-shaped support plate 71, a fixed sleeve 72, a moving rod 73, a second spring 74, a driving assembly 75 and a rubber pad 76. The fixing sleeves 72 are connected to both ends of the lower side of the clamping base 4. The moving rod 73 is inserted into the interior of the fixing sleeve 72. The second spring 74 is connected between the fixing sleeve 72 and the moving rod 73. The driving assembly 75 is arranged between the moving rod 73 and the fixing sleeve 72. The end of the moving rod 73 away from the fixing sleeve 72 is connected to the arc-shaped support plate 71. The side of the arc-shaped support plate 71 away from the moving rod 73 is connected to the rubber pad 76.

[0024] By adopting the above technical solution, after the entire device is installed on the electric heating pipeline using the installer 5, the driving component 75 is used to drive the moving rod 73 to move inside the fixed sleeve 72. The movement of the moving rod 73 drives the arc support plate 71 to move and the second spring 74 to stretch. When the arc support plate 71 is in contact with the electric heating pipeline, the driving component 75 is stopped. The arc support plate 71 can provide support for the entire device, thereby improving the installation stability of the entire device. Under the action of the rubber pad 76, the friction between the arc support plate 71 and the electric heating pipeline can be increased, thereby improving the stability of the overlap between the arc support plate 71 and the electric heating pipeline.

[0025] Specifically, the driving assembly 75 includes a rotating nut 751, an external rod 752, a moving opening 753, a fixed screw 754 and a fixed end block 755. One end of the moving rod 73 is connected to the external rod 752. The moving opening 753 is provided on the side wall of the fixed sleeve 72 at a position corresponding to the external rod 752. The fixed end block 755 is connected on the outer side wall of the fixed sleeve 72 and located below the moving opening 753. The fixed screw 754 is connected above the fixed end block 755.

The rotating nut 751 is connected on the outer side wall of the fixed screw 754 and located above the external rod 752.

[0026] By adopting the above technical solution, when the driving assembly 75 needs to be operated, the rotating nut 751 is rotated to rotate and move along the fixed screw 754. The movement of the rotating nut 751 drives the external rod 752 to move inside the moving opening 753. The movement of the external rod 752 drives the moving rod 73 to move, which is convenient for the operator to move the moving rod 73.

[0027] Specifically, a guide slider is connected to the side of the moving rod 73 away from the external rod 752, and a guide slot is provided on the inner wall of the fixed sleeve 72 at a position corresponding to the guide slider.

Under the sliding cooperation between the guide slider and the guide slider, a guiding effect can be provided for the movement of the moving rod 73, thereby improving the stability of the movement of the moving rod 73.

[0029] When this embodiment is used, the circuit is installed inside the box body 1 through the wiring mechanism 8, connected to the temperature control host inside the box body 1, and then connected to the electric heating pipeline by using the installer 5, so that the clamping base 4 and the box body 1 can be installed on the electric heating pipeline, and then the rotating nut 751 is rotated to rotate and move along the fixed screw 754. The movement of the rotating nut 751 drives the external rod 752 to move inside the moving port 753. The movement of the external rod 752 drives the moving rod 73 to move inside the fixed sleeve 72. The movement of the moving rod 73 drives the arc support plate 71 to move and the second spring 74 to stretch. When the arc support plate After 71 is attached to the electric heating pipeline, stop rotating the rotating nut 751. The arc-shaped support plate 71 can provide support for the entire device, improve the stability of the installation of the entire device, and under the action of the rubber pad 76, the friction between the arc-shaped support plate 71 and the electric heating pipeline can be increased, thereby improving the stability of the overlap between the arc-shaped support plate 71 and the electric heating pipeline. When in use, the temperature is adjusted using the temperature control knob 3. When the internal circuit of the box body 1 fails, the temperature control host inside the box body 1 transmits a signal to the alarm 2 to remind the surrounding staff to disassemble and replace the electric heating temperature controller;

The movement of the arc-shaped tightening plate 62 drives the first spring 65 to stretch. When the arc-shaped tightening plate 62 fits the electric heating pipeline, the rotation of the tightening screw 61 is stopped. Under the action of the arc-shaped tightening plate 62, the installer 5 and the electric heating pipeline can be tightened and fixed, ensuring that the installer 5 and the electric heating pipeline are tightened and fixed, thereby improving the stability of the connection between the box body 1 and the electric heating pipeline.

[0037] The working principle and use process of the utility model: the utility model installs the circuit into the box body 1 through the wiring mechanism 8, connects it with the temperature control host inside the box body 1, and then uses the installer 5 to connect it with the electric heating pipeline, so that the clamping base 4 and the box body 1 can be installed on the electric heating pipeline. After the installer 5 is installed on the electric heating pipeline, the tightening screw 61 is rotated to make it rotate and move along the external connection tube 64. The movement of the tightening screw 61 drives the connecting block 63 to move, and the movement of the connecting block 63 drives the arc-shaped tightening plate 62 to move. The movement of the arc-shaped tightening plate 62 drives the first spring 65 to stretch. When the arc-shaped tightening plate 62 fits the electric heating pipeline, stop rotating the tightening screw 61. Under the action of the arc-shaped tightening plate 62, the installer 5 and the electric heating pipeline can be tightened and fixed, ensuring that the installer 5 and the electric heating pipeline are tightened and fixed, thereby improving the stability of the connection between the box body 1 and the electric heating pipeline, and then turn the rotating nut 751 , so that it rotates and moves along the fixing screw 754, the rotating nut 751 moves to drive the external rod 752 to move inside the moving port 753, the external rod 752 moves to drive the moving rod 73 to move inside the fixing sleeve 72, the moving rod 73 moves to drive the arc support plate 71 to move and the second spring 74 to stretch.
