[0029] Specifically, a contact sensor 10 is fixedly connected to the top of the second support plate 7 , and the top of the contact sensor 10 overlaps the bottom of the knife 5 . The temperature sensor 11 is fixedly connected to the bottom of the first support plate 3 and the second support plate 7 .
[0030] By adopting the above technical solution and providing a contact sensor 10, it is possible to detect whether the knife 5 is in contact with the contact plate 9, and by providing a temperature sensor 11, it is possible to detect the bottom temperatures of the first support plate 3 and the second support plate 7.
[0031] Specifically, the tops of the first support plate 3 and the second support plate 7 are both threadedly connected with contacts 20 , and the number of contacts 20 is two. Baffles 8 are fixedly connected to both sides of the contact plate 9 , and the switch blade 5 is overlapped on the top of the baffle 8 .
