wherein the rotating handle 220 controls the external threaded column 218 to rotate to adjust the length of the extending internal threaded connecting sleeve 217, and the sliding sleeve 219 follows the external threaded column 218 to move synchronously along the axial direction to limit dust from contacting with the threads on the external threaded column 218.

Considering that the distance between the externally threaded column 218 and the plane is short, and the ground is more dusty and is easily contacted with the threads of the externally threaded column 218 at a decoration construction site, the thread engagement between the externally threaded column 218 and the internally threaded connecting sleeve 217 is failed.

The sliding sleeve 219 is sleeved outside the internal thread connecting sleeve 217 and the external thread column 218, the external thread column 218 is driven to synchronously rotate by rotating the rotating handle 220 so as to adjust the length of the external thread column 218 extending out of the internal thread connecting sleeve 217, the sliding sleeve 219 moves along the axis of the external thread column 218, is sleeved outside the external thread column 218 to limit dust from contacting with the thread of the external thread column 218, and ensures normal relative movement between the external thread column 218 and the internal thread connecting sleeve 217.

A plurality of fixing components 206 are arranged, each fixing component 206 comprises a U-shaped groove 221 arranged at the end of an external thread column 218, the inner wall of the U-shaped groove 221 is in threaded connection with a limiting bolt 222, a movable column 223 is arranged in the U-shaped groove 221 through a rotating shaft, a jack 237 for inserting the limiting bolt 222 is arranged on the movable column 223, a contact plate 224 is rotatably connected to the end of the movable column 223, and a plurality of locking holes 225 for the fixing bolts to pass through are formed in the contact plate 224;

here, the movable post 223 rotates around the axial section of the external threaded post 218, the contact plate 224 rotates around the axis of the movable post 223, and when the contact plate 224 contacts a plane parallel to the direction of gravity, the contact plate 224 is fixed to the plane by the fixing bolt, and the rotation of the movable post 223 is restricted by the limit bolt 222.

When the fixing assembly 206 is used, the contact plate 224 is in contact with the plane, and the contact plate 224 is limited to slide relative to the plane by static friction between the contact plate 224 and the plane, so that the support stability of the telescopic assembly 205 is ensured.

When the telescopic assembly 205 adjusts the supporting angle, the telescopic assembly 205 rotates around the rotating shaft, that is, the movable column 223 rotates around the axial section of the external threaded column 218, and simultaneously can rotate circumferentially around the contact plate 224, the position of the contact plate 224 relative to the telescopic assembly 205 can be flexibly adjusted, so that the contact plate 224 can adjust the position according to the planar actual condition, and the practicability are stronger.

When the contact plate 224 is connected to the wall, the contact plate passes through the locking hole 225 and is connected to the wall through the fixing bolt, the angle of the telescopic assembly 205 is adjusted to be parallel to the layered plate 202, so that the laser level is guaranteed to be horizontal, and meanwhile, the limiting bolt 222 is inserted into the insertion hole 237 to limit the rotation of the movable column 223, so that the stability of the laser level in the work process is guaranteed.

Secondly, the distance between the laser level meter and the wall is adjusted by adjusting the length of the external thread column 218 extending out of the internal thread connecting sleeve 217, so that the working range of the laser level meter is larger, and the practicability is stronger.

The contact plate 224 includes a plate body 226, an auxiliary member 227 and a plurality of sharp protrusions 228, the plate body 226 is rotatably connected to the movable column 223, one side of the plate body 226 extends outward in a radial direction of the layered plate 202 to be sharp-angled, the auxiliary member 227 is disposed on a contact surface of the plate body 226 and serves to assist in restricting the plate body 226 from sliding along a plane, and the sharp protrusions 228 are also disposed on the contact surface of the plate body 226.

The provision of the sharp protrusions 228 increases the static friction between the plate body 226 and the flat surface, further improving the stability of the contact between the contact plate 224 and the flat surface.

And the one end of plate body 226 is the closed angle form, when planar roughness is relatively poor, the contact surface between closed angle form and the plane through plate body 226 is littleer when adjusting telescopic component 205's support angle, more is convenient for support on the plane.

By the aid of the auxiliary assembly 227, when the plate body 226 is in contact with the plane, the connecting force between the plate body 226 and the plane is further improved, and the stability of the plate body 226 on the plane and the stability of supporting the laser level are further improved.

The contact surface of the plate body 226 is the side of the plate body 226 that contacts the flat surface.

The auxiliary assembly 227 comprises an inner groove 229 arranged on the contact surface of the plate body 226, a pushing bolt 230 extending to the other side of the plate body 226 is connected to the inner bottom of the inner groove 229 in a threaded manner, a suction cup 231 located in the inner groove 229 is arranged at the end of the pushing bolt 230, and the suction cup 231 is controlled to be in close contact with and attracted to the plane by the pushing bolt 230.

When the auxiliary assembly 227 is used, when the plane flatness is high, the plate body 226 rotates to push the suction cup 231 to be close to the plane through the pushing bolt 230 when contacting with the plane, and the connection force between the plate body 227 and the plane is enhanced through the vacuum adsorption of the suction cup 231 contacting with the plane, so that the stability of the telescopic assembly 205 and the fixed assembly 206 and the stability of the laser level instrument in the working process are further improved.

The fine adjustment alignment assembly 203, in use, supports the housing 1 by means of a plurality of adjustment screws 236 and connections to threaded sleeves 235.

When the laser level needs to be corrected, the length of the extending connecting threaded sleeve 235 is adjusted by rotating the adjusting screw 236, so that the distance between each part of the base body 1 and the layered plate 202 is changed to finish the horizontal correction of the laser level, meanwhile, the adjusting sliding seat 233 slides along the adjusting groove 232 to avoid interference caused by adjustment of the adjusting screw 236, when the horizontal correction of the laser level is finished, the locking bolt 234 is screwed to limit the sliding seat 233 to slide along the adjusting groove 232, and the stability of the laser level in the working process is ensured.
