[0002] In modern life, as people's requirements for the quality of home life increase, laser measurement products are used more and more widely in daily life. When construction workers are performing work such as pasting tiles on construction walls, in order to ensure that the tiles can be neatly pasted on the construction wall, construction workers usually use a laser level. The laser level is placed vertically on the ground in front of the construction wall, and then the laser beam generated by the laser level is imaged on the wall, and the laser beam line imaged on the wall is perpendicular to the ground. Construction workers can use this straight laser beam on the wall to neatly paste the tiles on the construction wall. The laser level can generate multiple vertical and horizontal laser planes to determine the horizontal and plumb direction accuracy, and is widely used in construction projects.

[0003] The laser level needs to be leveled before use. The commonly used laser levels cannot quickly position the laser level after leveling is completed, which makes the level easy to shake during use, affecting the use effect.

[0024] The beneficial effects of the present invention are:

[0025] 1. In the present invention, the laser level that is easy to position is placed in the use position, and then the pull ring is pulled downward to drive the pull rod and the insertion rod to move downward, so that the insertion rod is out of the slot, and then the threaded sleeve is rotated. The threaded sleeve drives the threaded column and the support plate up and down through the threaded transmission with the threaded column and under the guidance of the vertical rod. After the adjustment is completed, the pull ring is released, so that the insertion rod moves upward under the action of the compression spring and is inserted into the slot to lock the rotation of the threaded sleeve, and the lengths of the three support legs are adjusted in sequence to adapt to the placement position;

[0026] 2. In the present invention, the laser level that is easy to position controls the horizontal laser transmitter and the vertical laser transmitter to start and emit laser rays by pressing the touch button; at the same time, the output end of the electric push rod is controlled to shrink, thereby driving the locking plate to move downward. After the locking plate releases the lock on the counterweight plate, the counterweight plate rotates under the action of gravity, and the inner ring plate rotates in the middle ring plate, and the middle ring plate rotates in the outer ring plate, and the magnet is driven to move by the counterweight plate. The magnet drives the ball to move synchronously by magnetic attraction to the ball. During the movement, the ball drives the sliding seat to move through the ball seat and the cross plate. When the sliding seat moves left and right, the circular shaft is driven to rotate by the meshing of the first rack and the second gear. When the sliding seat moves forward and backward, it drives the crossbeam and the mounting frame to move forward and backward synchronously, and then drives the vertical shaft to rotate by the meshing of the first rack and the first gear. When the vertical shaft and the circular shaft rotate, the corresponding rotating box is driven to rotate. When the rotating box rotates, the two square plates move away from each other under the action of centrifugal force, and drive the two control buttons to move away from each other.

[0027] 3. In the present invention, the laser level for easy positioning, as the mounting seat and the counterweight plate gradually return to the vertical state, the sliding seat stops moving, the circular shaft and the vertical shaft stop rotating, and the rotating box stops rotating. The square plate is reset under the elastic force of the connecting spring so that the two control buttons are pressed against each other. When the four control buttons are pressed at the same time, the output end of the control electric push rod extends, driving the locking plate to move upward, and the rotation of the locking plate is limited by the contact between the locking plate and the bottom of the counterweight plate, thereby avoiding shaking during use;

[0028] 4. In the present invention, the laser level for easy positioning is driven by pulling the sliding ring downward to drive the two clamping plates out of the clamping slots, and then rotating the rotating ring to drive the baffle plate to move in a circle, so that the baffle plate is out of contact with the arc plate, thereby releasing the fixation of the transparent cover, so that the transparent cover can be moved upward to be disassembled;

[0029] 5. In the present invention, the laser level that is easy to position can realize automatic and rapid positioning after the laser level is automatically leveled through the cooperation of the provided linkage mechanism and the locking mechanism, thereby ensuring stability during subsequent use.
