[0030] The main unit 100 includes a base plate 101 and a furnace body 102. A rectangular block 103 is fixedly connected to the base plate 101. The furnace body 102 is located on the upper end of the rectangular block 103. Four connecting blocks 105 are symmetrically fixedly connected to the rectangular block 103. Each connecting block 105 has a connecting groove, and a fixing component 107 is provided in each connecting groove.

[0031] The alarm unit 200 includes a temperature-sensing optical fiber 201 and a mounting plate 202. The temperature-sensing optical fiber 201 is installed in the furnace wall of the furnace body 102. The mounting plate 202 is fixedly connected to the furnace body 102, and a fixing plate 203 is fixedly connected to the mounting plate 202. A temperature measuring host 204 is fixedly installed on the fixing plate 203. An alarm light 205 and an audible alarm 206 are installed on the mounting plate 202. The temperature-sensing optical fiber 201 collects temperature data in the furnace body 102. The temperature measuring host 204 receives the temperature signal transmitted by the temperature-sensing optical fiber 201, performs signal processing and data analysis. When an abnormal temperature rise is detected, it is determined that there is a gas leak in the furnace body 102. If a gas leak occurs in the furnace body 102, the alarm light 205 emits an alarm light, and the audible alarm 206 emits an alarm sound, which helps to remind the operator to deal with the situation in time and effectively prevents the gas leak accident from occurring in the furnace body 102.

The end of each threaded rod 107b facing away from the servo motor 107a is rotatably connected in the round hole. When the servo motor 107a is started, the output end of the servo motor 107a drives the threaded rod 107b to rotate. The threaded rod 107b drives the L-shaped rod 107d through the threaded sleeve 107c, which in turn moves the arc-shaped clamping plate 107e. The arc-shaped clamping plate 107e abuts against the arc-shaped insertion plate 106, clamping and fixing it, thereby fixing the furnace body 102.
