Make efficiency.
Preferably, the end of the protection shell is equipped with end cap.
By using above-mentioned technical proposal, end cap and protection shell are subjected to lid conjunction when storage, to be further reduced outer
Erosion of boundary's environment to ruler body, extends the service life of ruler body.
In conclusion the utility model has the following beneficial effects:
1, by setting protection shell, it can be avoided ruler body and directly contacted with the external world, reduce ruler body and collide with the external world,
The erosion of external environment is reduced, simultaneously so as to protect to ruler body；
2, by that shell will be protected to be set as detachable structure, it can facilitate and protection shell is mounted and dismounted, just
Use；
3, by protection shell on the inside of bolster is set, can protect shell buckle during to protection shell into
Row buffering reduces the impact force that ruler body is subject to and avoids the scale on ruler body because being vibrated to reduce the vibration that ruler body is subject to
And it falls off.
