[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 A vehicle left turn warning sound alarm includes an alarm body 1 and a mounting base 3. The bottom of the alarm body 1 is fixed with a mounting bracket 2 via bolts. The back of the mounting bracket 2 contacts the mounting base 3. A positioning pin 4 is fixedly connected to the side of the mounting base 3 near the mounting bracket 2. The positioning pin 4 slides through the mounting bracket 2. A locking sleeve 5 is fixedly connected to the vertical portion of the mounting bracket 2. A locking pin 6 is slidingly connected inside the locking sleeve 5. The locking pin 6 is plugged into the positioning pin 4. A spring 7 is provided inside the locking sleeve 5. One end of the spring 7 is fixedly connected to the locking pin 6, and the other end of the spring 7 is fixedly connected to the inner surface of the locking sleeve 5. The arrangement of the spring 7 can apply elastic force to the locking pin 6, so that it is always inserted into the positioning pin 4.

[0022] See also Figure 1 The locking pin 6 is fixedly connected to a lever 9 on its outer side. The lever 9 extends through the locking sleeve 5 and is slidably connected to the locking sleeve 5. A ball bearing 8 is provided on the portion of the locking pin 6 located within the locking sleeve 5, and the ball bearing 8 is slidably connected to the locking sleeve 5. The provision of the ball bearing 8 reduces the relative friction between the locking pin 6 and the locking sleeve 5.

[0023] See also Figure 1-2The upper end of the lock sleeve 5 is slidably connected to a slide rod 10, and the top of the slide rod 10 is fixedly connected to a connecting piece 11, and the end of the connecting piece 11 is fixedly connected to a clamping sleeve 12, and the clamping sleeve 12 is sleeved with the shift rod 9. The setting of the connecting piece 11 and the clamping sleeve 12 has the effect of preventing the shift rod 9 from being touched accidentally. The top of the shift rod 9 is fixedly connected to a rubber clamp 13, which passes through the clamping sleeve 12 and is clamped with the clamping sleeve 12. By setting the rubber clamp 13, the tightness of the combination between the clamping sleeve 12 and the shift rod 9 can be increased. The bottom of the slide rod 10 is fixedly connected to a limit block 14, and the limit block 14 is slidably connected to the inside of the lock sleeve 5. By setting the limit block 14, the slide rod 10 has a vertical stroke limiting effect.

[0024] The specific implementation process of the present utility model is as follows: when in use, first, pull the locking pin 6 through the lever 9 to retract it into the locking sleeve 5, and compress the spring 7, then fit the mounting frame 2 of the alarm body 1 to the mounting seat 3, and the locating pin 4 on the mounting seat 3 passes through the original bolt hole of the mounting frame 2, then release the lever 9, the locking pin 6 will be reset under the action of the spring 7, and inserted horizontally into the locating pin 4, thus completing the installation of the alarm body 1. In the later stage, it is only necessary to separate the locking pin 6 from the locating pin 4 through the lever 9 to disassemble and repair the alarm body 1. In addition, the sleeve 12 on the connecting piece 11 is put on the top of the lever 9 and fixed with the rubber clamp 13, which can prevent the lever 9 from being accidentally touched, thereby ensuring the stability of the installation of the alarm body 1.
