[0046] Before operation, the measuring component 6 is housed inside the storage compartment 5, which protects it, improving safety and extending the device's lifespan. When the measuring component 6 is needed, the knob 12 is activated. Driven by the knob 12, the threaded shaft 10 rotates in the guide groove 14 within the storage compartment 5. The threaded connection between the threaded shaft 10 and the moving block 11 causes the moving block 11 to slide upwards within the guide groove 14, thus moving the fixing plate 13 upwards inside the storage compartment 5 and removing the measuring component 6 from the storage compartment 5 for measurement. If the height of the measuring component 6 needs adjustment during use, the drive mechanism 16 is activated. Driven by 16, the drive gear 15 can rotate. Under the meshing action of the drive gear 15 and the driven gear 9, the driven gear 9 can rotate accordingly, thereby driving the internal threaded sleeve 8 to rotate in the connecting hole 17 inside the base 2. Under the threaded connection between the internal threaded sleeve 8 and the screw 7, the rotation of the internal threaded sleeve 8 can drive the screw 7 to move up and down, thereby driving the lifting platform 4 to move up and down accordingly, thus adjusting the measuring component 6 to the required height. During the movement of the lifting platform 4, the telescopic component 3 can extend and retract accordingly, and play a limiting role.
