detailed description

The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

As shown in Fig. 1, a kind of multifunctional distance measuring wheel disclosed by the present invention includes a handle 1, a mark button 2, a pause/continue button 3, an electronic device 4, a roller 5, a push rod 6 and a counter (not shown in the figure) . When measuring, when encountering an obstacle, press the pause/continue button 3 to suspend the counting of the counter, and after the obstacle is removed, press the pause/continue button 3 to start the counter to continue counting; during the measurement process, when certain positions When marking is required, press the marking button 2 to mark it on the generated action track in real time, and record the measurement data at the marking point at the same time.

Specifically, as shown in FIG. 2 , the handle 1 includes a handle connecting portion 11 and a handshake portion 12 , the handle connecting portion 11 is sleeved outside one end of the push rod 6 , and the handshake portion 12 is formed by extending the handle connecting portion 11 away from the push rod 6 A bent portion 13 is formed between the handle connection portion 11 and the handshake portion 12, a concave portion 14 is formed at the lower part of the bent portion 13, and an anti-slip structure 15 is formed below the handshake portion 12. When in use, the operator holds the handshake portion 13 with his index finger tightly The buckle recess 14 is convenient for operations such as pushing, pulling, and lifting the distance-measuring wheel, and can also facilitate the suspension of the distance-measuring wheel.
