In this embodiment: the surface of waist bench main part 104 is seted up to bleeder vent 3 and is made the steam when the baby learns to walk to scatter, the article that disappears can be placed to the rectangular channel 302, because of ventilative board 306 and rectangular channel 302 phase-match, it is more comfortable when can making the baby sit in second protection board 303 upside, need fix second protection board 303 when ventilative board 306 top, can be used to rotate screw 305, make screw 305 rotate and extend to ventilative board 306's top at the circumference inner wall of screw hole 304, thereby make the fixed top of firmly fixing at ventilative board 306 of rectangular channel 302.

The working principle and the using process of the invention are as follows: when the device is used by a person, the device shell 1 can be pulled by hand, so that the device shell 1 is separated from the connecting plate, the sleeve 204 is driven to slide on the surface of the second connecting rod 206, when the device slides to a certain degree, the sleeve 204 extrudes the third arc-shaped clamping block 208, the third arc-shaped clamping block 208 extrudes the second spring 207 at the side end, the second spring 207 is contracted, when the sleeve 204 extrudes to the middle part, the third arc-shaped clamping block 208 is driven to move forwards through the elastic ejection of the second spring 207, the third arc-shaped clamping block 208 is clamped in the clamping groove hole forwards through the third arc-shaped clamping block 208, the fixing device is used, the lifting clamping mechanism is fixed at the bottom end of the device shell 1, the height of the device shell 1 can be adjusted while the device shell 1 is more stable, an infant can be supported by the waist stool main body 104 when the infant has a rest when the infant walks, and the infant can walk more easily and easily, when a baby is put into the device, the first protection layer 108 presses the first protection layer 109, so that the first protection layer 109 abuts against the circumferential inner wall of the protection plate 203, the gap between the baby and the first protection layer 108 is reduced by the pressing of the first spring 202, and the baby is also greatly protected, when a person fixes the waist stool main body 104, the arc-shaped ligament 301 is pulled by hand to drive the square clamping block 308 with a fixed surface to move, the square clamping block 308 is clamped into the second square clamping groove 4 when moving, the square clamping block 308 is clamped to one third, the square clamping block 308 presses the rectangular clamping block 401 to ascend and presses the third spring 403 to contract, when the square clamping block 308 is clamped to two thirds, the third spring expands on the upper inner wall of the second square clamping groove 4 to drive the rectangular clamping block 401 with one end fixed to be clamped into the rectangular clamping groove 307, so that the waist stool main body 104 can achieve a fixing effect, and the baby can conveniently and conveniently learn to walk, and the arc ligament 301 is made of flexible materials, so that the effect is better on the waist of the nursing staff during detaching and binding.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
