[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Specific examples are given below.

[0022] See also Figure 1 to Figure 4A two-layer ladder stool comprises a first side frame 1, a second side frame 2, a connecting stop 3, a stool seat plate 4, a side stop 6 and a backrest panel 7. The first side frame 1 and the second side frame 2 are connected by the connecting stop 3. A stool seat plate 4 is installed between the first side frame 1 and the second side frame 2. A storage groove 8 is opened at the top of the first side frame 1 and the second side frame 2. A lower hinge block 9 is slidably installed in the storage groove 8, and an upper hinge block 10 is hingedly installed on the lower hinge block 9. A side stop 6 is installed on the upper hinge block 10, and a backrest panel 7 is installed between the two side stops 6.

[0023] The lower hinge block 9 includes a first hinge end 14 at the top and a mounting hole 15 on the side wall. A side groove 13 is provided on the top side wall of the first side frame 1, and a bolt passes through the side groove 13 and is connected to the mounting hole 15. The lower hinge block 9 also includes a first right-angled limiting portion 16. The upper hinge block 10 includes a second hinge end 17, and the second hinge end 17 is connected to the first hinge end 14 through a hinge shaft 11. The upper hinge block 10 also includes a second right-angled limiting portion 18 to realize the rotational connection between the lower hinge block 9 and the upper hinge block 10. When the step stool is used as a chair, the lower hinge block 9 and the upper hinge block 10 are stored in the storage groove 8. When the step stool is used as a ladder, the lower hinge block 9 and the upper hinge block 10 are located outside the storage groove 8 at a right angle, and the first limiting portion 16 and the second limiting portion 18 are engaged and limited.

[0024] The side walls of the first side frame 1 and the second side frame 2 are both provided with a first plug hole 5 and a second plug hole 12, and the side wall of the side block 6 is rotatably installed with a support rod 19 through an installation axis; when the stool seat plate 4 is parallel to the backrest panel 7, the pin 20 passes through the bottom end of the support rod 19 and the first plug hole 5; when the stool seat plate 4 is perpendicular to the backrest panel 7, the pin 20 passes through the bottom end of the support rod 19 and the second plug hole 12.

[0025] When the lower hinge block 9 and the upper hinge block 10 are in the same straight line, the lower hinge block 9 and the upper hinge block 10 are stored in the storage groove 8 of the side guard 6, the stool seat plate 4 is used for buttocks support, and the backrest panel 7 is used for back support;
