[0015] The control chip U1 may be STC89C52. Before normal operation, the user may burn the required program into the control chip U1 through a burner. The switch K2 may be used to reset the control chip U1. The battery box B1 may be used to install and replace the battery.

[0016] The traditional magnetic fixing structure only uses two permanent magnets to clamp and fix the temperature sensing line. This method requires manual separation of the two permanent magnets before use to leave room for the installation of the temperature sensing line. Since there is a large attraction between the two permanent magnets, it takes a certain amount of physical strength to separate the two permanent magnets. After separation, one worker is required to maintain the distance between the two permanent magnets, and another worker is required to install the temperature sensing line. This process is time-consuming and labor-intensive.

[0017] Now, an iron block is set on the movable plate and a coil L is set on the base, and a strong magnetic field is generated by energizing the coil L. The magnetic field is used to attract the iron block to drive the movable plate, so that the two groups of permanent magnets, magnet A and magnet B, and magnet C and magnet D, are separated. This method does not require much manual effort, saving time and effort.

[0018] During operation, the user can first close the switch K1 to start the power module. At this time, the battery in the battery box B1 first provides power to the control chip U1. At this time, the coil L is not powered to work. At this time, the two groups of permanent magnets, magnet A and magnet B, magnet C and magnet D, are still attached to each other, and the spring is in a stretched state.

[0019] Afterwards, press switch K3, and the control chip U1 sends an action command to relay J4. Relay J4 then energizes coil L. After energizing, coil L starts to work and generates a magnetic field. The magnetic field attracts the iron block, and the iron block drives the movable plate to move to the right along the guide rod until the attraction between the iron block and coil L and the elastic force generated by the spring compression plus the attraction between the two groups of permanent magnets generate a combined force that offsets each other. At this time, the distance between the movable plate and the fixed plate can be used to install the temperature sensing line.

[0020] After placing the temperature-sensing wire in the left installation slot, press the switch K4. At this time, the control chip U1 sends a disconnection command to the relay J4, and then the relay J4 will cut off the power to the coil L. After that, the magnetic field generated by the coil L will gradually weaken until no magnetic field is generated. In this process, the elastic force generated by the compression of the spring and the attraction between the two groups of permanent magnets will make the movable plate move to the left until the two groups of permanent magnets A and B, and C and D fit each other. At this time, the left installation slot and the right installation slot clamp the temperature-sensing wire, and then disconnect the switch K1 to turn off the power to complete the fixation of the temperature-sensing wire.

[0021] The utility model has the following beneficial effects: simple structure, convenient use, time and labor saving, and good fastening effect on the temperature sensing line. BRIEF DESCRIPTION OF THE DRAWINGS
