[0030] Described two-dimensional posture correcting learning appliance 4 comprises base 41, the support 42 that is fixedly connected with base 41, the column casing 43 that lower end is fixedly connected with support 42, the column 44 that lower end is movably connected with column casing 43 upper end, column There is a window frame 46 at the upper end of the 44, and the support 42 can drive the column casing 43 to rotate, and the window frame 46 can rotate relative to the column 44;

[0031] The base 41 is a rectangular block, the bottom of the base 41 has a projection 41a, and the projection 41a is an inverted T-shaped tenon; the projection 41a is inserted into the slot of the slot seat 11, so that the two-dimensional posture correcting learning tool 4 and the desktop 1 connect;

[0032] Described bearing 42 comprises left bearing 42a, right bearing 42b and rotating body 42c, and left bearing 42a is cylindrical shape, and left bearing 42a right end has first hole; Right bearing 42b right end is cylinder, and left end is Concave block, semicircular groove is arranged on the concave block, the cylinder left end of right support 42b has the second hole, and the second hole is embedded with the first plane toothed disc, the cylinder right end of right support 42b is opened There is a through hole, and the through hole communicates with the second hole; the left support 42a and the right support 42b are fixed on the base 41; the rotating body 42c is a stepped cylinder with small ends and a large middle, and the right end of the rotating body 42c is embedded with a second plane Sprocket, the second flat toothed disk is compatible with the first flat toothed disk, the left end of the rotating body 42c is matched with the shaft hole of the first hole, the right end of the rotating body 42c is matched with the shaft hole of the second hole, and the left support 42a is fixed on the right support In the groove at the left end of the seat 42b, the rotating body 42c is located in the groove at the left end of the right support 42b, and can rotate in the groove; the adjusting screw 42d runs through the through hole of the right support 42b, and is fixedly connected with the rotating body 42c, There is a wing nut at the right end of the adjusting screw 42d, and there is a spacer between the wing nut and the right support 42b. By rotating the wing nut, the rotating body 42c can be moved left and right, so that the second plane gear plate at the right end of the rotating body 42c is aligned with the right side. The first plane toothed discs of the support 42b are separated or matched to realize the rotation or positioning of the rotating body 42c;

[0033] The column sleeve 43 is a semicircular tube with an open upper end, and the column sleeve 43 is fixed in the middle of the rotating body 42c, so that when the rotating body 42c rotates, it can drive the column sleeve 43 to rotate, so that the column sleeve 43 and the desktop 1 form a clamp horn;

[0034] The cross-sectional shape of the column 44 is semicircular, and the lower end of the column 44 is located in the column sleeve 43; the top of the column sleeve 43 has a special-shaped tube locker 45, and the column 44 passes through the special-shaped tube locker 45 and the upper end of the column sleeve 43 connected, the special-shaped pipe locker 45 can lock the column 44 on the column casing 43;

[0035] The window frame 46 is spliced ​​by two cylindrical plastic tubes and two sheet plastic plates. The window frame 46 is generally rectangular in shape, and a shaft 46a is fixed in the middle of one of the plastic tubes. The outer diameter of the shaft 46a is equal to the inner diameter of the plastic tube.
