[0024] The base cover 6 is provided with an oblique limiting elongated hole 6-1. The high end of the limiting elongated hole 6-1 is higher than the opening height of any gear slot 12-2, and the low end of the limiting elongated hole 6-1 is lower than the bottom of any gear slot 12-2. The limiting elongated hole 6-1 is provided with a gear adjusting shaft 10 that can move up and down. The gear adjusting shaft 10 can be embedded in any gear slot 12-2 to lock the base cover 6 and the support part 12-1.
[0025] The base cover 6 is also equipped with a shift bracket 11 that can move back and forth. The tail of the shift bracket 11 has an upwardly curved part 11-1, and the curved part 11-1 has an arc-shaped drive hole 11-2. The high end of the drive hole 11-2 is opposite to the tail of the shift bracket 11 and is higher than the opening of any shift slot 12-2. The low end of the drive hole 11-2 is opposite to the head of the shift bracket 11 and is lower than the bottom of any shift slot 12-2. The shift shaft 10 is simultaneously limited within the drive hole 11-2. A shift bracket tension spring 9 is provided between the shift bracket 11 and the base cover 6. When the shift bracket 11 moves forward, it stretches the shift bracket tension spring 9. The spring 9 rebounds and resets the shift bracket 11. The head of the shift bracket 11 has a handle part 11-3, which is located below the front end of the base cover 6.

The handle part 11-3 can be pulled, the adjusting bracket 11 is moved to the front of the base, the driving long hole 11-2 is moved forward relative to the adjusting shaft 10, the adjusting shaft 10 is slid to the high end of the driving long hole 11-2, the adjusting shaft 10 is moved upward along the limiting long hole 6-1 until it is separated from the gear slot 12-2, and then the base upper cover 6 is unlocked, and the base upper cover 6 can be pulled forward to adjust the angle of the base upward inclination.
[0027] As Figures 4 to 6 As shown in the figure, the base of the child safety seat with adjustable base angle of the utility model is in the maximum inclination angle, at this time the base upper cover 6 is moved to the limiting long hole 6-1 relative to the gear slot 12-2 at the forefront of the supporting part 12-1, the handle part 11-3 is loosened, the adjusting bracket tension spring 9 is rebounded, the adjusting bracket 11 is reset relative to the base upper cover 6, the driving long hole 11-2 is moved backward relative to the adjusting shaft 10, the adjusting shaft 10 is slid to the low end of the driving long hole 11-2, the adjusting shaft 10 is moved downward along the limiting long hole 6-1 until it is embedded in the gear slot 12-2 opposite to it, and then the base upper cover 6 is locked again, so that the adjustment of the angle of the base upward inclination is completed.
[0028] If the angle of the base upward inclination is to be adjusted smaller, the base upper cover 6 is only needed to be unlocked and then pushed backward to the appropriate position, and then the adjusting bracket 11 is loosened to lock the base upper cover 6 again.
[0029] In the embodiment, the driving long hole 11-2 can also be arranged to be inclined, and the limiting long hole 6-1 can be arranged to be longitudinal. Embodiment 2
[0030] The difference between the embodiment and the embodiment 1 is that the high end and the low end of the driving long hole 11-2 are opposite to the head and the tail of the adjusting bracket 11 respectively, a compression spring is arranged between the adjusting bracket 11 and the base upper cover 6, the compression spring is rebounded to reset the adjusting bracket 11 when the adjusting bracket 11 is moved to the front of the base to compress the compression spring.
[0031] In the embodiment, the handle part 11-3 is pushed, the adjusting bracket 11 is moved to the rear of the base, the driving long hole 11-2 is moved backward relative to the adjusting shaft 10, the adjusting shaft 10 is slid to the high end of the driving long hole 11-2, the adjusting shaft 10 is moved upward along the limiting long hole 6-1 until it is separated from the gear slot 12-2, and then the base upper cover 6 is unlocked, and at this time the base upper cover 6 can be pulled forward to adjust the angle of the base upward inclination.
[0032] After the base upper cover 6 is adjusted to the proper position, the pull handle part 11-3 is loosened, the compression spring rebounds, the gear shifting support 11 is reset relative to the base upper cover 6, the driving long hole 11-2 moves forward relative to the gear shifting shaft 10, the gear shifting shaft 10 slides to the low end of the driving long hole 11-2, the gear shifting shaft 10 moves down along the limiting long hole 6-1 until it is embedded into the gear slot 12-2 opposite thereto, and the base upper cover 6 is locked again.
[0033] The above are only specific embodiments of the present application, and are not intended to limit the scope of the present application; if the present application is modified or replaced without departing from the spirit and scope of the present application, it should be covered in the protection scope of the present application.
