Schematic diagram；
Fig. 2 is the enlarged diagram of part A in Fig. 1.
Wherein, 100 it is measuring rod, 101 be measurement portion, 102 be pars contractilis, 103 be scale, 200 be sliding block, 201 is reading
Number slots, 300 be laser, 400 be inclinator, 500 be guardrail.
Specific embodiment
The core of the utility model be to provide it is a kind of for measuring the measuring tool of guardrail centre-height, how to reduce
The measurement error of guardrail centre-height.
In addition, embodiments illustrated below does not play any restriction effect to utility model content documented by claim.
In addition, the full content of composition represented by following example is not limited to the solution as utility model documented by claim
Necessary to scheme.
Fig. 1 and Fig. 2 are please referred to, the measuring tool for measuring guardrail centre-height of the utility model includes:
Measuring rod 100 is provided with scale 103 on measuring rod 100；
The sliding block 200 that can be slided on measuring rod 100 is provided with the reading slot that can expose scale 103 on sliding block 200
201；
Laser 300 on sliding block 200 is set, in the center line O1 and reading slot 201 of the launch hole of laser 300
