[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The temperature sensor is easy to install. When installing the probe, the probe is connected to the insertion slot. When the probe is inserted, it contacts the locking block. The locking block is moved by force due to the inclined upper surface. When the probe is inserted to the bottom, the locking slot is aligned with the locking block, so that the locking block enters the interior of the locking slot. The lower surface of the locking block is set to a plane to complete the locking.

When the drive shaft rotates, it will use the reset ring to compress the torsion spring. When the drive shaft rotates, it will use the second gear to drive the unlocking gear ring to rotate. When the unlocking gear ring rotates, it pulls the cable, and then uses the cable to move the locking block again, thereby completing the unlocking of the probe. Through the above structure, when unlocking, it can be completed by simply rotating the unlocking head, so that the disassembly efficiency is improved to a certain extent, thereby indirectly improving the overall replacement efficiency.
