[0002] Thermohygrometer is used to measure the temperature and humidity of the environment to determine the environmental conditions for product production or storage.

[0003] A search found that application number CN213632220U discloses a handheld thermometer and hygrometer. By installing an anti-slip hand clamp, an anti-slip pad, a connecting slider, a guide connecting rod and an anti-slip spring, the friction between the device and the user's hand can be increased to prevent the device from falling during use and causing damage to the device, which would affect the detection.

[0004] The above-mentioned device wraps the user's fingers by means of an anti-slip hand clamp, an anti-slip pad, a connecting slider, a guide connecting rod and an anti-slip spring.

If the anti-slip spring is too loose, it is not suitable for operators with thin fingers, resulting in insufficient applicability of the equipment. During use, the detection probe is protected by a movable protective shell. Long-term pushing and pulling causes the life of the limiting spring to be reduced, thereby affecting the service life of the equipment.
