Detailed ways

The present invention will be further described below with reference to the accompanying drawings.

As shown in Figure 1-3, Figure 7 and Figure 10, the housing 01 is provided with a laser ranging circuit 19 and a power supply 110 for supplying power to the laser ranging circuit, and the housing 01 is provided with a laser ranging port 111 , a display screen 112 and a work control switch 113 . When working, the laser is emitted from the laser ranging port through the work control switch, and the laser projected to the object is reflected and then received by the laser ranging port to realize the measurement, and display it on the display screen. Further, the power source can be a rechargeable battery, and a charging interface is configured at this time; the power source can also be a replaceable dry battery, and a battery cover 114 is configured at this time to open the battery cover to replace the dry battery.

The rangefinders shown in Figure 1-3, Figure 7 and Figure 10 are equipped with a pen clip structure for easy portability and storage. The pen clip structure includes a casing 01 and a clip 02 assembled at one end of the casing. The clip 02 is bent from a linear elastic material into a closed clamping section 21 and an assembly section 23 of the opening 22 (see Figures 4 and 8 ), The two free ends of the linear elastic material are located in the assembly section and form an opening 22 so that the assembly section can be opened. The casing 01 includes a main casing 11 and a cover 12 assembled on the main casing. One end of the main casing is provided with a fixing seat 13, The fixing base 13 is provided with an embedding groove 14 (see FIG. 5 and FIG. 8 ), the assembly section 23 of the clip 02 is located in the embedding groove 14 (see FIG. 6 ), the cover 12 has a limit groove 15 , and the assembly section 23 is located in the limit groove 14 Inside is restricted to open.

Referring to FIGS. 4 and 8 , in order to ensure reliable assembly, the clip, the housing and the fixing seat are uniformly stressed, and the assembly section 23 includes symmetrical side sections 24 and two barb sections 25 . Moreover, there is a transition section 26 between the clamping section and the assembling section, the end of the cover has a positioning groove 16, and the transition section 26 is positioned in the positioning groove 16 to avoid shaking. The barb section 25 is limited by the fixing seat 13, and the transition section 26 is limited by the positioning groove 16 to limit the position of the clip in the longitudinal direction of the casing, so as to prevent the clip from loosening or coming out in the longitudinal direction of the casing.
