It is more stable in the lifting of lifting plate.
More preferably：Dial is provided with the handle, is provided with the lifting plate and is engaged with dial
Tuning drive gear.
It is arranged such, during lifting plate realizes lifting, dial correspond to by the tuning drive gear on lifting plate
Radian scale, measurement head lifting how many angle can be more accurately known, can be effective when known hypotenuse is in how many degree
Control measurement head to rotate how many degree, so can more accurately measure required data, can be lifted to a certain extent
The accuracy of required measurement data.
More preferably：The spring for providing measurement head reset force is connected between the handle and measurement head.
It is arranged such, when lifting bar has been lifted, when needing lifting plate to be returned in horizontal direction, the elasticity of spring
Power enables to the relatively labor-saving reply of lifting plate.
In summary, the utility model having the beneficial effect that in contrast to prior art：
Acted on by the lifting of lifting plate and mix dial and tuning drive gear, enable to measurement head it is stable by level
Orientation measurement goes to vertical direction measurement, can improve the accuracy of ranging data to a certain extent.
