[0026] A slide groove 11 is provided on the inner bottom wall of the shell 10, the bottom of the slider 12 is slidably connected to the inside of the slide groove 11, the top of the slider 12 is fixedly connected to the bottom of the U-shaped block 16, the outer side wall of the first drive motor 13 is fixedly connected to the inner bottom wall of the shell 10, the output shaft of the first drive motor 13 is fixedly connected to one end of the screw rod 14, the outer side wall of the screw rod 14 is threadedly connected to the inside of the U-shaped block 16, the other end of the screw rod 14 is rotatably connected to the inner side wall of the shell 10, the outer side wall of the rod body 15 is slidably connected to the inside of the U-shaped block 16, and one end of the rod body 15 is fixedly connected to the inner side wall of the shell 10.

[0027] In one embodiment, the fixing assembly 201 includes a spring 20, a first plate 21, a sensor body 22, a fixing plate 23, a sleeve 24, a buckle 25 and a temperature sensitive element 26; one end of the spring 20 is fixedly connected to the inner wall of the U-shaped block 16, the other end of the spring 20 is fixedly connected to the bottom of the first plate 21, one end of the fixing plate 23 is hinged to the top of the U-shaped block 16, and a sleeve 24 is installed on one side of the U-shaped block 16. Through the setting of the U-shaped block 16, the spring 20, the fixing plate 23 and the sleeve 24 are fixed. Through the setting of the spring 20, when the sensor body 22 is vibrated, the first plate 21 is pressed down, and the spring 20 generates a reverse thrust to prompt the first plate 21 to reset, thereby reducing the impact of vibration on the sensor body 22.
