The two connecting blocks 14 are respectively fixedly welded to both ends of the limiting rod 11. First elastic springs 15 are sleeved on the two slide rods 13. The two ends of the first elastic spring 15 are respectively fixedly connected to the fixed seat 12 and the connecting block 14. The elastic force of the arranged first elastic spring 15 acting on the connecting block 14 can enable the limiting rod 11 to be inserted into the limiting groove 9 of the limiting wheel 6 when there is no external force, so as to limit the limiting wheel 6.

[0024] The bottom end of one of the slide rods 13 is fixedly welded with an L-shaped connecting rod 16. The bottom end of the L-shaped connecting rod 16 is fixedly welded with a first pedal 17. During adjustment, the first pedal 17 can be stepped on with the foot to drive the L-shaped connecting rod 16 to move downward, thereby driving the slide rod 13 to slide downward.

[0027] Working principle: During the use of this utility model, when it is necessary to adjust the projection angle of the life-saving projector body 8, one can hold the grip on the life-saving projector body 8, and then step on the first pedal 17 downward with one foot, so that the first pedal 17 drives the L-shaped connecting rod 16 to move downward, thereby driving the sliding rod 13 to slide downward, compressing the first elastic spring 15. At the same time, the sliding rod 13 drives the limiting rod 11 to move downward through the connecting block 14 to disengage from the limiting groove 9. Then, turn the life-saving projector body 8 up and down for angle adjustment. After adjusting the angle, release the first pedal 17, so that the limiting rod 11 is inserted into the corresponding limiting groove 9 under the elastic force of the compressed first elastic spring 15, thereby limiting and fixing the life-saving projector body 8. The operation is simple and fast, realizing the convenient projection angle of the life-saving projector body 8. When it is necessary to adjust the projection direction, step on the second pedal 22 downward to drive the insertion rod 23 to disengage from the corresponding slot 19. Then, rotate the life-saving projector body 8 so that it rotates through the rotational cooperation of the mounting seat 2, the rotating column 18 and the base 1. When the life-saving projector body 8 rotates to the required direction, release the second pedal 22, so that the insertion rod 23 is inserted into the corresponding slot 19 under the elastic force of the second elastic spring 24, making the mounting seat 2 limited and fixed, realizing the convenient adjustment of the projection direction of the life-saving projector body 8.
