[0019] Example

[0020] Please see Figures 1-4 In this embodiment, a laser lamp-assisted positioning device is provided, including a base 1, a connecting sleeve 2, a rotating cylinder 3, a fixed disc 4, a laser lamp 5, a rotating device 6, and a ratchet device 7. The base 1 has four screw holes 101 of the same size. The base 1 and the rotating cylinder 3 are connected by the connecting sleeve 2. The rotating device 6 and the ratchet device 7 are installed between the base 1 and the connecting sleeve 2. The laser lamp 5 is fixed to the head end of the rotating cylinder 3 by the fixed disc 4.

[0021] Specifically, the first end of the rotating cylinder 3 is provided with a first rectangular groove 301 and a second rectangular groove 302. The upper end of the groove is provided with four second screw holes 303 of the same size. The end of the rotating cylinder 3 is installed in the second cavity 201 of the connecting sleeve 2.

[0022] The laser light 5 is installed inside the first rectangular groove 301. The rectangular protrusion 401 on the lower side of the fixing disk 4 is installed inside the second rectangular groove 302. The upper side of the fixing disk 4 is provided with four screw holes 402 of the same size. The laser light 5 is fixed in the second screw hole 303 and the third screw hole 402 by nuts 403, so that the laser light 5 will not be loose during use and avoids problems such as double spots and flashing.

[0023] The base 1 has a cavity 102 inside the left cylindrical cavity, and a cylindrical groove 103 is provided on the side wall of the cylinder. A fixed cylinder 702 is installed on the side of the cylindrical groove 103.

[0024] A rotating device 6 is installed in the first cylindrical groove 103. The rotating device 6 has a ball groove 601. Multiple balls 602 are installed in the ball groove 601. A rotating disk 603 is installed at the other end of the ball 602. A second cylindrical groove 604 is provided in the middle of the rotating disk 603.

[0025] A cylindrical protrusion 701 is installed inside the second cylindrical groove 604. The cylindrical protrusion 701 is connected to a ratchet 708. A pawl 706 is provided on the right side of the ratchet 708. A second fixing cylinder 703 is installed on the upper side of the pawl 706. A spring 704 is connected between the first fixing cylinder 702 and the second fixing cylinder 703. A circular hole 705 is provided in the middle of the pawl 706. The pawl 706 is fixed by a third fixing cylinder 707 installed in the circular hole 705 and the first cylindrical groove 103.

[0026] The working principle of this utility model is as follows:

[0027] When using a laser light-assisted positioning device, the four screw holes 101 of the base 1 are fixed to the platform by nuts 403, and the laser light 5 is installed in the first rectangular groove 301 and fixed by the fixing disc 4. When the angle of the laser light 5 needs to be adjusted, the rotating cylinder 3 can be rotated for adjustment. The end of the rotating cylinder 3 is equipped with a connecting sleeve 2, which is connected to a ratchet device 7. When the ratchet 708 rotates, it will squeeze the pawl 706, causing the pawl 706 to spring up and allowing the ratchet 708 to rotate smoothly. Under the action of the spring 704, the pawl 706 will rebound when it is not squeezed, so that the ratchet 708 will not rotate, thus keeping the laser light 5 in a stationary state and avoiding problems such as double spots and flashing during use.
