Abstract
Description

This method not only increases the construction process, reduces the operation efficiency, and increases the labor cost, but also goes against the concept of reducing costs and increasing efficiency.

The structure and working principle of this part are prior art and will not be repeated here. The pendulum 3 adjusts the gravity direction of the pendulum 3 through the cross-axis mechanism 2, thereby driving the laser module 4 to complete the adjustment so that the emitted laser line is in the horizontal and plumb line direction.
[0031] The frame 1 includes a base plate 11 and four columns 12 integrally formed and vertically fixed on the base plate 11, and the cross-axis mechanism 2 is arranged at the upper end of the column 12; a left claw 5 and a right claw 6 are rotatably connected to the base plate 11, and the left claw 5 and the right claw 6 are hinged to each other. A switch assembly 7 is arranged on the base plate 11, and when the switch assembly 7 is pushed, the left claw 5 and the right claw 6 can be driven to move toward or away from each other to lock and disengage the pendulum body 3 respectively.
[0032] Specifically, two rotating columns 13 are integrally formed and vertically fixedly connected to the bottom plate 11, the left claw 5 and the right claw 6 are rotatably connected to the corresponding rotating columns 13 respectively, a waist-shaped hinge hole 51 is opened on the left claw 5, and a hinge shaft 61 is integrally formed and fixedly connected to the right claw 6, the hinge shaft 61 is rotatably and slidably inserted into the hinge hole 51, and a shift block 62 is integrally formed and fixedly connected to the right claw 6 on the right claw 6, and the switch assembly 7 can drive the shift block 62 to drive the left claw 5 and the right claw 6 to move toward or away from each other.
