then, the measuring laser body 18 is started, light rays of the measuring laser body 18 can also irradiate an external ruler through the transparent window 50 of the front cover, at the moment, two light spots are longitudinally distributed, through the height difference between the two laser spots, the rotating angle of the measuring laser adjusting sleeve 9 is amplified through the rotating angle amplifier 11, more obvious representation can be carried out on the feedback pointer 12, and the distance between the measuring starting point and the measuring key point can be calculated by combining the number indicating multiplying power of the measuring multiplying power dial 49 locked by the feedback pointer 12 (the calculation principle is that the tangent value of the included angle of the two light rays = the longitudinal height difference of the two laser spots/the transmission distance of the light rays emitted by the fixed reference laser 8);
when the distance between two light spots is too close (calculation error is too large), or light emitted by the measuring laser body 18 irradiates on the ground (without irradiating on a scale), the screw rod knob 41 needs to be manually rotated, when micro-adjustment is performed (the screw rod knob 41 is slowly rotated), the sliding block 36 is driven to slide along the guide shaft 34 through transmission between the transmission screw rod 35 and the inner ball nut 37, the guide shaft 34 compresses and stretches the pre-tightening spring bodies 38 at two ends respectively when sliding, so that the sliding sealing piston 39 is driven to slide in the hydraulic decelerating transmission pipe 22, and under the action of transmission liquid at two ends, the arc-shaped cylindrical swinging piston 19 and the measuring laser body 18 are pushed to rotate, so that the horizontal angle of the measuring laser body 18 is adjusted;
because the pre-tightening spring bodies 38 can be compressed to different degrees, the swinging of the arc-shaped cylindrical swinging piston 19 is delayed and slow relative to the sliding block 36, but because the pre-tightening spring bodies 38 are always in a compressed state and have pre-tightening force, the two groups of pre-tightening spring bodies 38 can be restored to an isometric state;
when the adjustment is carried out to a large extent (the screw rod knob 41 is rotated rapidly), the moving speed of the sliding block 36 is high, the recovery speed of the pre-tightening spring body 38 cannot follow the sliding speed of the sliding block 36, at the moment, the transmission lifting rod 40 can drive the arc-shaped cylindrical swinging piston 19 to swing rotationally through the swinging rod 20 at the bottom of the piston in the process of following the movement of the sliding block 36, the horizontal angle of the measuring laser body 18 is adjusted, and after the adjustment is finished, the pre-tightening spring body 38 can still be slowly recovered to the initial length;
the reading and calculation can be started until both laser spots are irradiated on the external scale and the distance between the two spots is appropriate.
The above is the overall working process of the invention, and the steps are repeated when the device is used next time.
