The working principle is as follows:

first application scenario (measurement using tape 9):

when the product of the invention is in a normal and unused state, the round head is just clamped at the outer port of the guide chute body 6 (driven by the spring coiling device 3).

The user first activates the detection assembly, the interaction assembly and the control assembly through the key module 15.

The user then pinches the round head and pulls out the tape 9 to take the measurement.

In the process that the tape 9 moves in the guide groove 6, two photoelectric sensors detect the change of the corresponding grating strips in real time (wherein, the grating strips on the absolute grating strips 27 are a series of absolute codes, and an accurate position value can be directly obtained according to the read absolute codes as long as the encoder is powered on) (wherein, the incremental grating strips 26 are composed of periodic scribed lines, the reading of the position information requires reference points, and the stretched length value of the tape 9 is calculated by comparing the reference points with the reference points; since the position value must be determined by the absolute reference points, one or more reference points are engraved on the incremental grating ruler, and the position value determined by the reference points can be accurate to a signal period, namely resolution).

The user can see from the display 14 the amount of length the tape 9 is stretched, i.e. the size of the object being measured.

Second application scenario (measurement using a single distance sensor 30):

the user first activates any one of the distance sensors 30 and the control and interaction components through the key module 15.

The user then holds the product of the invention and directs the activated emitting end of the distance sensor 30 directly towards the object to be measured, so as to measure the desired data (the user reads the measured data from the display screen 14).

A third application scenario (measurement using two distance sensors 30):

the user first activates the two distance sensors 30 and the control and interaction components via the key module 15.

Then, the user holds the product of the present invention and directs the emitting ends of the two distance sensors 30 to the two ends of the target to be measured respectively, so as to measure the required data (the user reads the measured data from the display 14) (for example, when measuring the arm spread (height) of the measured person, the measurer can set light blocking pieces (blocking pieces are set on the head of the user) at the two ends of the two hands of the measured person, and then the measurer holds the product of the present invention and directs the emitting ends of the two distance sensors 30 to the two blocking pieces (blocking pieces and the ground) respectively, so as to measure the arm spread (height) of the measured person).

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
