It is assemblied in 17 horizontal adjustables in the third adjustment hole, and the end of third adjusting rod 17 is articulated with the back of laser reflection plate 15
Face.By Level tune third adjusting rod 17, can vertical verticality to laser reflection plate 15 and horizontal vertical degree adjust
Section.The third adjustment hole can be threaded hole, and correspondingly, third adjusting rod 17 is the screw rod or spiral shell being screwed together in third adjustment hole
Bolt, the mode being connected through a screw thread realize third adjusting rod 17 in the horizontal adjustable in third adjustment hole.Further, it is also possible to adopt
It uses telescopic rod as third adjusting rod, the telescopic end of telescopic rod is passed through into third adjustment hole and is hinged with laser reflection plate 15.
In the present embodiment, laser reflection plate 15 uses rectangular panel body, the back side four corners corresponding to laser reflection plate
It is respectively arranged with above-mentioned third adjusting rod 17, totally four third adjusting rods 17, is horizontally disposed with, and threaded one end is connected to adjusting base
In third adjustment hole on plinth 16, the other end is articulated with the back side of Laser emission plate 15 by flexural pivot 151.Flexural pivot 151 has sphere
Can spherical shell two parts constitute, sphere is set in spherical shell, and sphere can rotate in spherical shell, but the rotation of the two be only can be around common
The centre of sphere relatively rotate.The spherical shell of flexural pivot is fixed on the back side four corners of laser reflection plate 15, and the sphere of flexural pivot is fixed on
The end of three adjusting rods 17 can avoid individually adjusting four using flexural pivot articulated connection laser reflection plate 15 and third adjusting rod 17
When certain root in root third adjusting rod, cause the stress deformation of laser reflection plate 15, it is ensured that the tune between four third adjusting rods
Section will not interfere with each other and protect laser reflection plate.
Cooperate shown in Fig. 4 again, checks that the ruler support 19 of ruler device is vertically installed on the reflecting surface of laser reflection plate, can be used
Ruler support 19 is adsorbed on the reflecting surface of laser reflection plate by the mode of magnet absorption, in order to remove inspection ruler after inspection
Device, will not influence the actual measurement of range unit and retaining device, and magnet 193 is mounted on the close laser reflection plate of ruler support 19
One end on.Inspection ruler ruler body 18 is graduated scale, and the origin of scale is located at the center for checking ruler ruler body, and the two sides of origin form two
Duan Kedu, scale value are gradually increased from origin to two sides.Check that ruler ruler body 18 is set in ruler support, when in use perpendicular to ruler support 19
And it is parallel to laser reflection plate, make the reflection kernel for checking that the origin of ruler ruler body 18 corresponds to laser reflection plate.
Wherein, ruler support 19 is made of a L-square 191 and a directing plate 192, and the L-square 191 is further by mutually in 90 °
Two gussets be spliced, crest line where two gussets are mutually 90 ° of side is that the right angle of the L-square 191 is stupefied.Magnet 193 is installed
On L-square 191, when in use, L-square 191 is adsorbed on the reflecting surface of laser reflection plate by magnet.Directing plate 192
It is fixed on L-square 191, and directing plate 192 is mutually perpendicular to L-square 191, i.e. directing plate 192 and laser reflection plate is mutual
Vertically.The a line of directing plate 192 it is stupefied with the right angle of L-square 191 is stupefied is overlapped (i.e. volume is located at same straight line), constitute directing plate
192 leading edge is stupefied.Therefore, the junction of L-square 191 and directing plate 192 constitutes a rib body angle point.
Check that ruler ruler body 18 is set on the directing plate 192, the mode for checking that pivot joint can be used in ruler ruler body 18 is rotationally connected with
On the directing plate 192, can rotate to parallel or vertical with directing plate 192, during installation, will check ruler ruler body rotate to draw
Guide plate 192 is parallel, is easily installed and folding, is checking in use, will check that the rotation of ruler ruler body is vertical as directing plate 192, i.e.,
It is parallel with laser reflection plate, and make reflection kernel of the origin in alignment with laser reflection plate for checking ruler ruler body.
The origin of ruler ruler body and the reflection kernel of laser reflection plate are checked for the ease of alignment, when installing ruler support 19, first
Ensure the stupefied reflection kernel in alignment with Laser emission plate in the right angle of L-square 191, since the leading edge of directing plate 192 is stupefied and right angle
The right angle of plate 191 is stupefied positioned at same straight line and perpendicular to the reflecting surface of laser reflection plate, and therefore, the leading edge is stupefied stupefied with the right angle
The reflection kernel of place adjusting to a line Laser emission plate is simultaneously vertical with laser reflection plate.As long as at this point, control detection ruler ruler body 18
When rotating perpendicular as directing plate, the leading edge that the origin of detection ruler ruler body 18 is narrowly focused towards directing plate 192 is stupefied
Guarantee that the origin of detection ruler ruler body 18 is parallel to laser reflection plate in alignment with the reflection kernel and detection ruler ruler body of laser reflection plate.
