[0028] In order to better understand the purpose, structure and function of the present invention, the handheld rangefinder of the present invention is further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5As shown, a handheld rangefinder of the present invention includes a rangefinder housing 1, a slot 8 is provided on the surface of the rangefinder housing 1, an inserting plate 14 is inserted into the inner side of the slot 8, a surface of the inserting plate 14 is fixedly connected to the first pressing plate 3, a surface of the first pressing plate 3 is fixedly connected to the first connecting rod 15, a surface of the first connecting rod 15 penetrates the first through-hole 16, and the other end of the first connecting rod 15 is fixedly connected to the first protective plate 19, a surface of the first protective plate 19 is fitted with the receiver 6, so that through the protective structure of the receiver 6, when using the rangefinder, pressing the first pressing plate 3 and the second pressing plate 27 will open the first protective plate 19 and the second protective plate 20, and no It affects the use. When the first protective plate 19 protects and covers the receiver 6, it can protect the receiver 6 to a great extent, press the surface of the slot 8 to fix the fixed column 10, the surface of the fixed column 10 is sleeved with the slide tube 11, and a spring 12 is provided on the surface of the slide tube 11. One end of the spring 12 is fixedly connected to the surface of the slot 8, and the other end of the spring 12 is fixedly connected to the first pressure plate 3. In this way, when the rangefinder accidentally slips, the first pressure plate 3 will rebound under the action of the spring 12. At this time, the first protective plate 19 will automatically cover the receiver 6 and the transmitter 5 to prevent them from directly causing bumps, thereby greatly increasing the protection performance of the receiver 6 and the transmitter 5.

[0030] A slide groove 21 is provided on the surface of the rangefinder housing 1, a slider 22 is inserted into the inner side of the slide groove 21, the surface of the slider 22 is fixedly connected to the protective shell 2, the surface of the protective shell 2 is fixedly connected to the first magnetic block 23, the surface of the protective shell 2 is fixedly connected to the second magnetic block 24, and the surface of the rangefinder housing 1 is fixedly connected to the iron block 25. The protective shell 2 structure fully covers the handheld rangefinder, so that dust will not enter the inside of the protective shell 2 when it is idle to a large extent, thereby greatly reducing the difficulty of cleaning the device.

[0031] A second through-hole 18 is provided on the surface of the first protective plate 19, and a second connecting rod 17 is inserted into the inner side of the second through-hole 18. The surface of the second connecting rod 17 is fixedly connected to the second protective plate 20. The surface of the second protective plate 20 is in contact with the transmitter 5, and the other end of the second connecting rod 17 is fixedly connected to the second pressure plate 27. In this way, when the rangefinder accidentally slips, the first pressure plate 3 will rebound under the action of the spring 12. At this time, the first protective plate 19 will automatically cover the receiver 6 and the transmitter 5 to prevent them from directly causing collisions, thereby greatly increasing the protection performance of the receiver 6 and the transmitter 5.

[0032] The surface of the rangefinder housing 1 is fixedly connected to the first stop frame 9, and the surface of the plug plate 14 is fixedly connected to the second stop frame 13. In this way, when the spring 12 rebounds the first pressure plate 3 and the second pressure plate 27, the first stop frame 9 and the second stop frame 13 will not fall off, thereby greatly increasing the practicality of the device.

[0033] An anti-slip strip 4 is provided on the surface of the first pressing plate 3, and an anti-slip strip 4 is provided on the surface of the second pressing plate 27. By providing the anti-slip strip 4 on the first pressing plate 3 and the second pressing plate 27, the friction coefficient is improved when the handheld rangefinder is held manually, thereby greatly improving the anti-slip performance of the device.

[0034] A charging slot 26 is provided on the surface of the rangefinder housing 1, and a dust cover 7 is inserted into the inner side of the charging slot 26. In this way, a dust cover 7 is provided on the protective shell 2 to prevent dust from entering the charging slot 26 to a large extent. In this way, by providing the dust cover 7, dust is prevented from entering the charging slot 26 to a large extent, and the difficulty of cleaning the device is greatly reduced.

[0035] The working principle of the handheld rangefinder is as follows: when using the handheld rangefinder, first open the protective shell 2 through the slide slot 21. When using, press the first pressure plate 3 and the second pressure plate 27 by hand. At this time, the first protective plate 19 and the second protective plate 20 can be opened through the first connecting rod 15 and the second connecting rod 17, so as not to affect the use of the receiver 6 and the transmitter 5. To a great extent, the protection of the receiver 6 and the protector is improved when not in use. When the handheld rangefinder accidentally slips, the first pressure plate 3 and the second pressure plate 27 will rebound under the action of the spring 12. At this time, the first protective plate 19 and the second protective plate 20 will automatically cover the receiver 6 and the transmitter 5 to prevent them from directly causing collisions, thereby greatly increasing the protection performance of the receiver 6 and the transmitter 5. When the handheld rangefinder needs to be used, the protective shell 2 structure is provided to fully cover the handheld rangefinder, so that dust will not enter the interior of the protective shell 2 when it is idle. In addition, a dust cover 7 is provided on the protective shell 2 to prevent dust from entering the charging slot 26 to a great extent, thereby greatly reducing the difficulty of cleaning the device.

[0036] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
