The telescopic rod 3 has a connecting line 307 inside, and one end of the connecting line 307 is connected to the moving block 2, and the other end of the connecting line 307 is connected to the rangefinder body 1.

[0021] As a technical optimization of this utility model, screws 308 are symmetrically rotatably connected to both sides of the mounting base 306, and one end of the screw 308 is threadedly connected to the side surface of the ball seat 3010. The screw 308 can adjust the angle of the rangefinder body 1 and further improve the turning flexibility of the rangefinder body 1.

[0022] As a technical optimization of this utility model, slide rails 201 are fixedly connected to both sides of the movable block 2, and a slot 202 is provided at one end of the slide rail 201. A sliding groove 103 is provided on the inner side wall of the mounting groove 102, and the sliding groove 103 is aligned with the slide rail 201. After the movable block 2 is stored in the inner side of the mounting groove 102, the slide rail 201 and the sliding groove 103 can limit the movable block 2, thereby improving the stability of the movable block 2 and preventing the movable block 2 from shaking.

[0023] As a technical optimization of this utility model, the two sides of the rangefinder body 1 are symmetrically slidably connected with limit rods 104, and a spring 106 is fixedly connected to the inner surface of the limit rod 104. One end of the spring 106 is fixedly connected to the outer surface of the rangefinder body 1, and one end of the limit rod 104 is fixedly connected to a limit block 105. The limit block 105 is aligned with the slot 202. The limit rod 104, the limit block 105 and the spring 106 can limit the movement block 2, and prevent the movement block 2 from sliding out after it is stored in the mounting slot 102.

[0024] As a technical optimization of this utility model, a strap 302 is fixedly connected to the lower surface of one end of the telescopic rod 3, and a hook and loop fastener 303 and a hook and loop fastener hook 304 are fixedly connected to the outer surface of one end of the strap 302.

By the cooperation of the strap 302 and the binding ring 305 on the lower surface of the telescopic rod 3, the telescopic rod 3 can be tied to the worker's hand to prevent the moving block 2 from slipping.

[0025] As a technical optimization of this utility model, the lower surface of the telescopic rod 3 is fixedly connected with an anti-slip rubber pad, and the strap 302 is made of sweat-absorbing cotton material.

[0026] When using this invention, if a worker needs to measure the distance to a target at a height, first pull the limiting rods 104 on both sides of the rangefinder body 1. At this time, the limiting rods 104 will drive the limiting block 105 away from the inside of the slot 202, and then push the moving block 2 to slide out of the mounting slot 102. After that, the worker rotates the screw 308 to turn the rangefinder body 1 and make the rangefinder body 1 rotate to a certain angle. Then, the worker rotates the rangefinder body 1 horizontally so that the laser beam 101 at one end of the rangefinder body 1 is aligned with the target. Then, the worker pulls the telescopic rod 3 to extend the telescopic rod 3. At this time, the worker holds the moving block 2 and then passes one end of the strap 302 through the binding ring 305. Then, the worker uses the Velcro surface 303 and the Velcro hook surface 304 to bind the moving block 2 and the telescopic rod 3 to the worker's hand. After that, the worker can lift the rangefinder body 1 to make the measurement.
