The fixing block 8 is fixedly connected to the interior of the sensor body 1 through the fixing mechanism, a cavity is provided between the two slide grooves, and an adjustment mechanism is provided inside the cavity. The two fixing mechanisms are matched with the adjustment mechanism, and a limiting mechanism is provided at one end of the adjustment mechanism, and the limiting mechanism matches the adjustment mechanism.

[0026] The battery module 7 is inserted into the upper surface of the battery base 6, and then it can serve as a power supply. When the power of the battery module 7 is used up, the fixing block 8 can be opened to remove the battery module 7, and then a new battery module can be replaced, so that the temperature sensor can continue to be used to prevent waste.

[0027] In order to fix the fixing block 8, Figure 1-3 As shown, the fixing mechanism includes two screw rods 9, two sleeves 10 and two first bevel gears 11. The two screw rods 9 are rotatably connected to the inside of the corresponding slide groove, and the two sleeves 10 are threadedly sleeved on the rod wall of the corresponding screw rod 9. One end of the two screw rods 9 passes through one side of the slide groove and extends to the inside of the cavity. The two first bevel gears 11 are fixedly sleeved on the rod wall of the corresponding screw rod 9. The inner wall of the sensor body 1 is symmetrically provided with two fixing grooves, and the two fixing grooves are matched with the corresponding sleeves 10 respectively. The adjustment mechanism includes a rotating rod 12, a second bevel gear 13, a slider 14 and a knob 15. The rotating rod 12 is rotatably connected to the lower surface of the inside of the cavity, the second bevel gear 13 is fixedly sleeved on the rod wall at the lower end of the rotating rod 12 and meshes with the two first bevel gears 11. A square groove is provided at the upper end of the rotating rod 12, the slider 14 is slidably arranged inside the slider 14, and the knob 15 is fixedly connected to the upper surface of the slider 14.

[0028] When the battery module 7 is inserted above the battery base 6, the fixing block 8 can be used to block the battery module 7 to prevent the battery module 7 from separating from the battery base 6. Then, the knob 15 is rotated to make the slider 14 drive the rotating rod 12 to rotate. Then, the two first bevel gears 11 and the second bevel gear 13 are used to drive the two screw rods 9 to rotate.
