And the device does not need to be close to a building during measurement, so that potential safety hazards are reduced.

Preferably, a groove is arranged on the bearing platform, the groove is matched with the first measuring arm, and the first measuring arm can be accommodated by the groove. Through set up the recess on the cushion cap, can prevent that the first measuring arm of digital display bevel protractor from sliding, improve the rate of accuracy of measurement.

Preferably, still include the centering rod, the centering rod with the cushion cap is connected, can adjust the horizontal position of cushion cap through the centering rod, improves measurement accuracy.

Preferably, the centering rod is detachably connected with the bearing platform, so that the centering rod and the bearing platform are more convenient to move and store.

Preferably, the detachable connection is a threaded connection, so that the connection firmness of the centering rod and the bearing platform is improved.

Preferably, the distance measuring instrument is a laser distance measuring instrument, and the distance measuring speed and the accuracy can be improved.

Preferably, the bearing platform is of a stainless steel structure, so that the service life of the bearing platform is prolonged, and the cost is reduced.

Preferably, the second measuring arm is detachably connected to the rangefinder so that the rangefinder may be detached when not in use.

Preferably, the groove is internally provided with an anti-slip pad, so that the digital display angle ruler can be further prevented from sliding.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the measuring staff passes through the utility model discloses a distancer and digital display bevel protractor cooperate, just can measure the length and the width of building, have improved measuring efficiency. And the device does not need to be close to a building during measurement, so that potential safety hazards are reduced.

2. The utility model discloses a set up the recess on the cushion cap, can prevent that digital display bevel protractor from sliding, improve the measuring rate of accuracy.
