Description
Technical Field
[0001] The utility model relates to the technical field of measuring instruments, in particular to a measuring instrument. Background Art
[0002] A handheld rangefinder is an instrument for distance measurement based on the principles of electromagnetic waves, optics, acoustics, etc. and has a compact body. The principle is: when working, the handheld rangefinder emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target.
[0003] Most existing handheld distance meters are powered by electricity. Once the battery is exhausted, they will be unable to measure. In this case, users usually choose manual measuring tools such as tape measures instead. However, in actual use, the two measuring tools are inconvenient to carry and it is inevitable that they will be forgotten. The lack of practicality leads to reduced measurement efficiency. Therefore, we propose a measuring instrument. Utility Model Content

[0031] Example 2
[0032] like Figure 1-4 As shown, the housing 201 is fixedly connected to the rangefinder body 1. Through the fixed connection between the housing 201 and the rangefinder body 1, the measuring mechanism 2 and the rangefinder body 1 can be made more firmly connected, and the stability of use can be improved. At the same time, the portability can also be improved to prevent forgetting to carry a manual measuring tool. The fixing block 203 is welded to the folding ruler 202, and the card slot 204 is adapted to the folding ruler 202. Through the welding of the fixing block 203 and the folding ruler 202, it is convenient to pull the folding ruler 202 out of the housing 201. During measurement, the fixing block 203 can also fix the corresponding end of the folding ruler 202 and the object to be measured, thereby improving the stability of use. The fixing rod 205 is fixedly connected to the housing 201, and the folding ruler 202 is rotatably connected to the fixing rod 205. 5, the folding ruler 202 can be more smoothly drawn out from the inside of the housing 201, and at the same time, the end of the folding ruler 202 close to the fixing rod 205 can be fixed to prevent it from falling off, thereby improving the stability of use. The threaded rod 207 is adapted to the threaded opening 206. Through the adaptation of the threaded rod 207 and the threaded opening 206, the threaded rod 207 can be rotated to make the end extending to the inside of the housing 201 be inserted into the fixing groove 208.
