[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0016] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation to the present application.

[0017] ​Embodiment 1: The spring mattress connected by folding net, comprising a bottom plate 1, a plurality of adjusting springs 2 are arranged on the bottom plate 1, a protective cover 6 is arranged on each adjusting spring 2, the thickness of the protective cover 6 is 1cm, a V-shaped folding net 5 is arranged between each protective cover 6, the V-shaped folding depth of the folding net 5 is 3cm, two upper edges of the folding net 5 are connected with two adjacent adjusting springs 2 respectively, the V-shaped bottom end of the folding net 5 is connected with a pull rope 4, the lower end of the pull rope 4 is connected with a tension spring 3, the lower end of the tension spring 3 is fixedly connected with the bottom plate 1, the lower end of the adjusting spring 2 is connected with a screw rod 7, the lower end of the screw rod 7 is threadedly connected with a gear II 8 through a screw hole 11, two adjacent gear IIs 8 are engaged with each other, the outermost gear II 8 is engaged with a gear I 9, the gear I 9 is connected with a handle 10, and the gear II 8 and the gear I 9 are arranged on the bottom plate 1 through a fixing piece 12.
