As improvement, described hall sensing number of sensors is two, in turn be arranged in the wheel seat along circumference, the output of each hall sensing sensor removes to connect two signal input parts of the microprocessor in the control circuit, to signal sequence, can judge measuring wheel and be just changes or reverse microprocessor by two sensor measurements like this, thereby to make present range data be increase or deduct, made things convenient for the user, and simple and practical.
Improve, described handle is connected with spike by adapter sleeve rotationally with pivot pin again, and extension spring between spike and the adapter sleeve is convenient to wheeled type distance measuring apparatus and is opened spike and put.
As improvement, described wheel seat top has jointing, link together by adapter sleeve and handle, wheel shaft is arranged on the wheel seat centre, measuring wheel is put on wheel shaft by the intermediate sleeve borehole jack, and carrying out axial limiting with locating part, wheel cap and measuring wheel link together, and use with convenient the manufacturing.
Improve again, be connected to pattern MODE respectively between a plurality of input mouths of described microprocessor and the VCC end, store STORE, read READ, remove the CLEAR functional switch, accordingly, corresponding functional software module is housed in microprocessor, select different working method and function by functional switch, be convenient to the user and manipulate.
At last, described handle is to adopt telescopic handle, and use is easy to carry.
Compared with prior art, the invention has the advantages that: adopt the magnet steel element to cooperate with the hall sensing sensor, can avoid the disturbing effect of extraneous weather and foreign matter, measure to disturb and lack, precision is more increased, and, automatically the counter-rotational distance of measuring wheel is detained from present range data and go, use conveniently, overall construction design is reasonable and practical, assembling is produced easily, uses convenient.
