         4 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 1 , wherein each of the connection bases comprises a vertical extension portion, a first horizontal extension portion, and a second horizontal extension portion that intersect and are fixedly connected to each other, any two of extension directions of the vertical extension portion, the first horizontal extension portion, and the second horizontal extension portion are perpendicular to each other, and the first notch, the second notch, and the third notch are respectively provided in the vertical extension portion, the first horizontal extension portion, and the second horizontal extension portion. 
     
     
         5 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 4 , wherein the first horizontal extension portion and the second horizontal extension portion both have an inverted “U”-shaped cross section, so as to respectively form the second notch and the third notch, and inverted “U”-shaped reinforcement ribs are provided on inner walls of the first horizontal extension portion and the second horizontal extension portion. 
     
     
         6 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 4 , wherein the vertical extension portion is provided with an insertion hole extending vertically, the insertion hole is in insertion fit with the second end of a corresponding one of the multiple first support frames, an elastic buckle is fixed to the second end of the corresponding one of the multiple first support frames, and at least one slot used to be in clamping fit with the elastic buckle is provided in an external side surface of the vertical extension portion corresponding to the insertion hole. 
     
     
         7 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 6 , wherein the vertical extension portion comprises a first protection plate and a second protection plate disposed vertically and intersecting each other, an inner corner between the first protection plate and the second protection plate is fixedly provided with a pillar extending vertically, the insertion hole is disposed in the pillar, and an inner side of the pillar is fixedly provided with the first notch. 
     
     
         8 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 4 , wherein external edges of an intersection part between the vertical extension portion, the first horizontal extension portion, and the second horizontal extension portion are rounded. 
     
     
         9 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 1 , wherein the skeleton further comprises a runner and multiple second support frames corresponding to the quantity of the multiple first support frames, the runner is relatively disposed below the notch, a first end of each of the multiple second support frames is hinged to the runner, and a second end of each of the multiple second support frames is hinged to a corresponding one of the multiple first support frames, such that the runner relatively approaches the notch, so as to extend the skeleton, or the runner relatively leaves the notch, so as to retract the skeleton. 
     
     
         10 . The skeleton assembly of an umbrella-shaped canopy on top of a playpen according to  claim 9 , wherein a lower end of the notch is provided with a locked shaft extending downwards, and the runner is correspondingly provided with a locking hole for the locked shaft to insert; the runner is further provided with an elastic locking mechanism configured to lock the locked shaft in the locking hole or unlock the locked shaft from the locking hole.
