[0023] A lock body square core paddle anti-gap structure comprises a box body 1, an upper paddle 2, a lower paddle 3 and a paddle spring assembly 5, wherein the box body 1 is provided with a large torsion spring limiter 11, a large torsion spring arm limiter 12, a small torsion spring hole 13, a lower paddle limiter 14, a handle paddle hole 15 and a small torsion spring limiter 16, and the lower paddle limiter 14 is provided with a limiter groove 141.

[0024] The upper paddle 2 is provided with an upper paddle hole 22 in the middle, limiting holes 21 on both sides, and a torsion spring arm hole 23 on one side of the upper paddle 2. The lower paddle 3 is provided with a lower paddle hole 32 in the middle, limiting columns 31 corresponding to the limiting holes 21 on both sides, and a lower paddle limiting groove 33 and a compression spring clamping position 34 on one side of the lower paddle 2.

[0025] The upper paddle 2 and the lower paddle 3 are fixed together on the handle paddle hole 15, the upper paddle hole 22, the lower paddle hole 32 and the handle paddle hole 15 correspond to each other, the limiting column 31 is embedded in the limiting hole 21, and the limiting column 31 has a certain moving space in the limiting hole 21; the lower paddle limiting groove 33 is stuck in the limiting plate groove 141 on the lower paddle limiting plate 14.

[0026] A large torsion spring 4 is provided outside the handle nut hole 15 , and the large torsion spring 4 passes through the large torsion spring limiter 11 , a torsion spring arm at one end of the large torsion spring 4 is embedded in the large torsion spring arm limiter 12 , and a torsion spring arm at the other end is embedded in the torsion spring arm hole 23 of the upper plectrum 2 .

[0027] The paddle spring assembly 5 includes a small torsion spring 51 and a compression spring 52. The middle of the small torsion spring 51 is fixed in the small torsion spring hole 13. The torsion spring arm at one end of the small torsion spring 51 is clamped in the torsion spring arm hole 23 of the upper paddle 2, and the other end is limited between the small torsion spring limiter 16 and the edge of the box body 1.
