[0034] Furthermore, the lead screw 35 is rotatably connected to the support block 3 via the worm gear 33. The lead screw 35 is used to drive the lifting plate 38 to rise and fall, thereby driving the protective cover 310 to rise and fall. The limiting plate 36 is in the shape of a circular plate and is used to limit the lifting plate 38 to prevent the lifting plate 38 from detaching from the lead screw 35. The limiting rod 37 is in the shape of a circular rod and is used to limit the lifting plate 38 to prevent the lifting plate 38 from rotating with the rotation of the lead screw 35, thereby realizing the rising and falling of the lifting plate 38. The lifting plate 38 is plate-shaped.
[0035] Furthermore, the lifting plate 38 is slidably connected to the lead screw 35 and the limiting rod 37. The lifting plate 38 is used to drive the support rod 39 and the protective cover 310 to rise and fall. When the measuring instrument 25 is not in use, the protective cover 310 can be controlled to rise and cover the lens of the measuring instrument 25, thereby preventing the lens of the measuring instrument 25 from being damaged due to accidental tilting. When the measuring instrument 25 is in use, the protective cover 310 can be controlled to fall, so that the protective cover 310 will not affect the use of the measuring instrument 25.

The protective cover 310 is used to protect the measuring instrument 25 and prevent the lens of the measuring instrument 25 from being damaged due to accidental tilting.
[0036] Working principle: Pulling the pull rod 26 causes the insert block 23 to disengage from the mounting block 24. Then, rotating the limiting threaded sleeve 27 limits the pull rod 26, allowing the measuring instrument 25 to be disassembled. This makes it convenient for users to disassemble the measuring instrument 25, avoiding the need for external tools during disassembly and bringing great convenience to users.
[0037] Rotating the worm gear 32 drives the worm wheel 33 and the lead screw 35 to rotate, which controls the lifting plate 38 to rise and fall, thereby controlling the lifting of the protective cover 310. When the measuring instrument 25 is not in use, the protective cover 310 can be raised to cover the lens of the measuring instrument 25, thus preventing the lens of the measuring instrument 25 from being damaged due to accidental tipping. When the measuring instrument 25 is in use, the protective cover 310 can be lowered so that the protective cover 310 does not affect the use of the measuring instrument 25.
