[0016] The advantages of the present invention are:

[0017] 1. Turn the hexagonal nut to drive the threaded joint to rotate and fix it to the temperature measurement device, and the fixing nail is also fixed to the device. The external temperature is transmitted to the bimetallic temperature sensing element 1 and the bimetallic temperature sensing element 2 through the temperature sensing tube. The bimetallic temperature sensing element 1 and the bimetallic temperature sensing element 2 sense the temperature and deform, driving the connecting shaft 1 and the connecting shaft 2 to rotate, the bevel gear 1 and the bevel gear 2 to rotate, driving the connecting rod 1 and the connecting rod 2 to rotate, driving the bevel gear 4 and the bevel gear 7 to rotate in the same direction, driving the bevel gear 5 and the bevel gear 6 to make a circular motion with the connecting rod 2 as the axis, driving the bracket 1 and the bracket 2 to make a circular motion with the connecting rod 2 as the axis, driving the turntable 1 to rotate, the bevel gear 9 and the connecting shaft 3 to rotate, driving the lower joint and the connecting piece 1 to rotate, driving the upper joint to rotate, driving the connecting shaft 4 The pointer rotates to display the temperature. When one of the bimetallic temperature sensing element 1 and the bimetallic temperature sensing element 2 is broken, for example, the bimetallic temperature sensing element 2 is broken, then only the connecting shaft 1 rotates, driving the bevel gear 1 to rotate, driving the bevel gear 3 and the connecting rod 1 to rotate, driving the bevel gear 4 to rotate, driving the bevel gear 5 and the bevel gear 6 to rotate in two opposite directions. Since the bevel gear 7 does not rotate, it drives the bracket 1 and the bracket 2 to make a circular motion with the connecting rod 2 as the axis, driving the turntable 1 to rotate, the bevel gear 9 and the connecting shaft 3 to rotate, driving the lower joint and the connecting piece 1 to rotate, driving the upper joint to rotate, driving the connecting shaft 4 and the pointer to rotate, and then displaying the temperature. Therefore, the two sets of bimetallic temperature sensing elements greatly reduce the possibility that the thermometer cannot be used when the temperature sensing elements are damaged.

[0018] 2. Turning the knob drives the horizontal frame to rotate, drives the upper joint to rotate, drives the over-temperature alarm unit to rotate, and then changes the angle of viewing the temperature. When encountering vibration, it drives the outer shell 1 to shake slightly left and right, drives the connecting plate 1 to move slightly left and right, drives the shock-absorbing outer tube and the piston rod to rub left and right, drives the piston to move slightly left and right in the shock-absorbing outer tube. When the piston moves to the left, a small amount of liquid on the left side of the piston enters the right side of the piston through the fine hole, drives the long rod to move right, drives the plugging piece 2 to contact the piston, and prevents more liquid from flowing to the right. When the piston moves to the right, a small amount of liquid on the right side of the piston enters the left side of the piston through the fine hole, drives the long rod to move left, and drives the plugging piece 1 to contact the piston, preventing more liquid from flowing to the right. Therefore, it plays a buffering role to prevent the instrument from being shattered.

[0019] 3. When the temperature is too high, the pointer rotates, driving the metal rod to rotate, and the metal sheet 1 and the metal sheet 2 are respectively in contact with the metal rod, driving the transmission line 1 to contact with the transmission line 2, and the plug is inserted into the power supply.

If the temperature continues to be too high, the pointer continues to rotate, driving the metal rod to push the metal sheet 1 and the metal sheet 2 to rotate, driving the slide 1 and the slide 2 to rotate at the limit pointer (3-9, and then the highest temperature when the temperature is found to be too high can be displayed.
