Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, being linearity measurer described in the utility model comprising laser range finder 1, fixed pedestal
2, magnetic scale 3 and firm banking 4；Wherein, laser range finder 1 is for providing the laser source of ranging；Fixed pedestal 2 is for solid
Determine laser range finder 1 and laser range finder 1 is passed through into magnetic absorption on pipeline 5；Magnetic scale 3 is used as laser range finder 1
Laser target spot；Firm banking 4 has permanent magnetism, for magnetic scale 3 to be fixed on pipeline 5；Preferably, firm banking 4
For magnetic suction disc.Specifically, magnetic scale 3 is arranged on firm banking 4 by magnetic, the lower end of magnetic scale 3 and fixed bottom
The lower end of seat 4 is concordant, and through magnetic absorption on one end of pipeline 5, laser range finder 1 is arranged in fixed pedestal 2 firm banking 4
On, fixed pedestal 2 is arranged on the other end of pipeline 5, is oppositely arranged laser range finder 1 with magnetic scale 3, to make Laser Measuring
The laser projection point of distance meter 1 is fallen on magnetic scale 3.
Specifically, as shown in Fig. 2, fixed pedestal 2 includes adjusting screw rod 21 and base body 22；Wherein, adjusting screw rod 21
For adjusting the state of laser range finder 1, so that the laser rays of laser range finder 1 is parallel with 0 ° of line of pipeline 5 or 90 ° of lines, protect
