 The present invention will be further described below in conjunction with the accompanying drawings.

 A toddler walker as shown in FIG. 1 is identical in construction to an existing walker, and includes an upper tray 1, a chassis 2, and legs for connecting the upper chassis, including a front side leg 3 And two back legs 4. The upper and the chassis have a ring structure, the front plate of the upper plate 1 is provided with a dining plate 11, the back side is provided with a backrest 12; and the lower corner of the lower side of the chassis 2 is provided with a pulley 21. The chassis 2 has an inner ring opening area larger than the upper plate 1, and can accommodate the upper plate 1 and a portion of the rear side legs 4. The inner ring of the chassis 2 is provided with a recess 24 for accommodating a portion of the rear side legs 4.

 Detailed structural analysis As shown in FIG. 2 and FIG. 3, the lower end of the front side leg 3 is provided with a plug end 31 detachably inserted into the middle of the front end of the chassis 2, and the upper end can be inserted inward through the rotating shaft 32 and the mounting bracket 34. Rotating and connecting to the upper tray 1. The lower end of the rear side leg 4 is rotatably connected to the rotating seat 23 provided on both sides of the rear end of the chassis 2 through the eccentric rotating shaft 43. The upper end is engaged with the knob card shaft 41 through the knob 42 and is rotatably mounted on the outer side of the rear end of the upper disc 1. .
