Stacking when accumulating, and being also convenient for transport.
Preferably, being equipped with the second T-connecting piece, the 2nd T between the front support rod and preceding foot lever and rear foot lever
Three free ends of shape connector are connect with the upper end of the lower end of front support rod, the upper end of preceding foot lever and rear foot lever respectively；Then T shape
Make folded support rod, preceding foot lever and the stacking of rear foot lever more smooth after connector setting, advantageously reduces volume, and
Stacking when being readily transported.
Preferably, the lower end of the second connection rod rear end and back support rod is coaxially connected on rear leg；Then in this way
After setting, the second connecting rod and back support rod is laterally movable is restricted, so as to fold stress more stable for the utility model, into one
Step reduces folding resistance, and the second connecting rod and back support rod support preferably, are conducive to increase the utility model use after expansion
When overall structural strength.
Preferably, the rear end of the first connecting rod and the front end of the second connecting rod are coaxially hinged on third connecting rod
Lower end；Then in this way after setting, the front end of first connecting rod rear end and the second connecting rod is laterally movable to be restricted, so that this is practical
New type foldable stress is more stable, further decreases folding resistance, and after being unfolded first connecting rod and the second connecting rod support compared with
It is good, be conducive to further increase overall structural strength when the utility model is used.
Preferably, the upper end of the third connecting rod and the front end of casing are coaxially connected on front support rod；In this way
After setting, the upper end of third connecting rod is laterally movable to be restricted, so that the utility model folding stress is more stable, is further dropped
Low folding resistance, the support that rear sleeve is unfolded is preferable, and then can increase the stress of cushion frame, to improve making for the utility model
Use stability.
