It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, a portable rangefinder for engineering cost includes an overall structure 1 and an auxiliary structure 2, wherein the auxiliary structure 2 is located at the center of the front outer surface of the overall structure 1; the overall structure 1 includes a box body 101, a handle 104 is fixedly connected at the center of the top of the box body 101, Velcro 105 is fixedly connected to the top and bottom of the rear outer surface of the box body 101, a telescopic rod 108 is fixedly connected to the top and bottom of the inner surfaces of both sides of the box body 101, a clamping plate 110 is fixedly connected to the protruding end of the telescopic rod 108, an anti-slip pad 111 is fixedly connected to the center of the inner surface of the clamping plate 110, a compression spring 109 is fixedly connected to the outer surface of the telescopic rod 108, and a rangefinder body 106 is slidably connected to the center of the rear inner surface of the box body 101.

[0024] The effect achieved by the entire embodiment 1 is that during use, the user can fix the whole thing on the wrist by setting the Velcro 105, and by setting the handle 104, the user can lift the whole thing, so that the two methods are provided for the user to choose, so that the subsequent user can carry it at any time, thereby improving the overall convenience. When the telescopic rod 108 is extended or retracted, it will drive the splint 110 and the anti-skid pad 111 to move back and forth horizontally, so that the splint 110 and the anti-skid pad 111 can be normally When the two sides of the rangefinder body 106 are in contact, the contact can be clamped and fixed to ensure that the rangefinder body 106 can be stably located in the box body 101 to avoid displacement in the box body 101. In addition, by providing the anti-slip pad 111, the friction between the rangefinder body 106 and the rangefinder body 106 is increased to further ensure that the rangefinder body 106 can be stably located in the box body 101. When clamping, the clamping plate 110 also utilizes the expansion force of the compression spring 109 and the extension force of the telescopic rod 108 to effectively apply force to the rangefinder body 106.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, a ventilation pipe 102 is provided through the center of the inner surfaces of both sides of the box body 101, and a filter screen 103 is fixedly connected to the inner surface of the ventilation pipe 102. The interior of the ventilation pipe 102 is connected to the interior of the box body 101, one end of the compression spring 109 is fixedly connected to the outer surface of the clamping plate 110, and the other end of the compression spring 109 is fixedly connected to the inner surface of the box body 101. The outer surfaces of both sides of the rangefinder body 106 are slidably connected to the outer surfaces of the clamping plate 110 and the anti-slip pad 111, and the auxiliary structure 2 includes a transparent baffle 201, and handles 202 are fixedly connected to the two sides of the front outer surface of the transparent baffle 201, and the outer surface of the transparent baffle 201 is slidably connected to the inner surface wall of the slot 107.

[0026] The effect achieved by the entire embodiment 2 is that the provision of the ventilation tube 102 can ensure the air circulation in the box body 101, and the provision of the filter 103 can filter the dust in the air to prevent the dust and air from entering the ventilation tube 102 together, and the provision of the transparent baffle 201 can facilitate the user to check the rangefinder body 106 at any time, and the mutual cooperation of the card slot 107 and the handle 202 can facilitate the user to take down the transparent baffle 201, and then take out the rangefinder body 106 for use, such as Figure 3 As shown, the rangefinder body 106 is located in the box body 101 , which can protect the rangefinder body 106 and prevent the rangefinder body 106 from colliding with external objects and being damaged when not in use, thereby increasing the service life of the rangefinder body 106 .

[0027] Working principle: In actual use, the user can fix the whole on the wrist through the cooperation of two Velcro strips 105 for subsequent use, and the setting of the handle 104 makes it easy for the user to lift the whole, so that the user can carry it with him, making it more convenient for the user to use. When the rangefinder body 106 is needed, the transparent baffle 201 is pulled forward by the handle 202. After being pulled to a certain position, the transparent baffle 201 can be separated from the card slot 107. After separation, the telescopic rod 108 is reset, and the user can take out the rangefinder body 106 for use. When not in use, the user puts the rangefinder body 106 into the box body 101. Through the setting of the telescopic rod 108, the compression spring 109, the clamping plate 110 and the anti-slip pad 111, the rangefinder body 106 can be clamped and fixed to ensure that it can always be stably in the box body 101, and then the transparent baffle 201 is put back into the card slot 107 by the handle 202.
