The button body 2 comprises a top block 21, a boss 22 and a first clamping block 26. The boss 22 is arranged on the bottom surface of the top block 21 and is integrally formed with the top block 21. A first opening 23 extending to the bottom surface of the boss 22 is opened on the top surface of the top block 21. A hinge shaft 24 is fixed to the inner wall of the first opening 23. A swing arm 25 is hinged on the hinge shaft 24. Specifically, the swing arm 25 A circular hole is provided in the middle, and the hinge shaft 24 is inserted through the circular hole to realize the swing arm 25 to swing around the hinge shaft 24. The hinge shaft 24 is welded and fixed to the inner wall of the first opening 23. A convex block 251 is provided at the bottom of the swing arm 25, and a spring sleeve 252 is provided at the top. A spring 253 is installed in the spring sleeve 252. The convex block 251 and the spring sleeve 252 are on the same side. The top block 21 is provided with a spring support column 211 on the side wall of the first opening 23. The spring support The spring 253 is pressed against the first inner hole side wall 252 by the spring 253, and the protrusion 251 protrudes from the protrusion 22 outer wall by the protrusion 22. By pressing the top of the swing arm 25 in the direction of the spring support column 211, the swing arm 25 swings, and the protrusion 251 shrinks into the notch 221 to be hidden, pressing the spring 253 to the limit, and the protrusion 251 is still in the notch 221. The protrusion 251 is limited by the two side walls of the notch 221, and the swing arm 25 is not easy to swing left and right along the hinge shaft 24. The protrusion 22 is set as a circular column, and the top block 21 is preferably a circular block. The center of the top block 21 is in the same straight line with the axis of the protrusion 22 and the center of the first opening 23.
[0018] Reference Figure 1The first clamping block 26 is a circular block and one side of it is uprightly provided with four first elastic pieces 261.

The swing arm 25 can be conveniently controlled by the control handle 27 to swing the swing arm 25.
[0020] Reference Figure 2 and Figure 3The button cap 1 includes a locking block 11 and a second clamping block 12. The locking block 11 and the second clamping block 12 are both circular blocks. A groove 111 is recessed in the middle of one side of the locking block 11. The groove 111 is circular and matches the shape and size of the boss 22. The side wall of the groove 111 is recessed with a card slot 112. The card slot 112 is annular and is used to clamp the protrusion 251. Four second elastic pieces 121 are erected on one side of the second clamping block 12. The four second elastic pieces 121 are arranged at intervals around the center of the first clamping block 26. The outer side surface of the end of each second elastic piece 121 is convexly provided with a second card block 122. The top surface of the locking block 11 is recessed with four second through grooves 113. The four second through-grooves 113 are arranged at intervals around the center of the locking block 11, and the side walls of the four second through-grooves 113 away from the center of the locking block 11 are all recessed with second limiting grooves 114 for clamping the second clamping block 122. When in use, a perforation is provided on the clothing fabric, the locking block 11 is located on one side of the fabric and the second through-grooves 113 are directed toward the fabric and the second through-grooves 113 are aligned with the perforations, the second clamping block 12 is located on the other side of the patching material, and the four second elastic sheets 121 on the second clamping block 12 pass through the perforations and respectively penetrate into the four second through-grooves 113, and the second elastic sheet 121 is pressed against the side wall of the second through-grooves 113 away from the center of the top block 21, so that the second elastic sheet 1 21 is deformed. When the second clamping block 122 on the second elastic piece 121 moves to the position of the second limiting groove 114, the second elastic piece 121 is reset and the second clamping block 122 is clamped in the second limiting groove 114 to be limited, so that the second clamping block 12 and the locking block 11 are fixed and clamp the cloth, and the button cap 1 is not easy to fall off the cloth. By toggling the swing arm 25 to further compress the spring 253, the swing arm 25 swings so that the protrusion 251 is received in the notch 221, and the boss 22 is inserted into the groove 111. The compression of the spring 253 is released so that the spring 253 rebounds and the top of the swing arm 25 is pressed against the hole wall of the first opening 23 again. The swing arm 25 swings so that the protrusion The block 251 protrudes from the notch 221 again to the outer wall of the boss 22 and is inserted into the slot 112 to obtain the limitation of the slot 112, so that the button cap 1 and the button body 2 are fastened together to close the clothes. By compressing the spring 253 again, the protrusion 251 shrinks into the notch 221 to avoid it, so that the button body 2 is separated from the button cap 1, and the clothes are opened. The button body 2 is fastened to the button cap 1 and unlocked by the protrusion 251, which is convenient for increasing the limiting surface of the button cap 1 on the button body 2. The button cap 1 is not easy to fall off the button body 2 when in use, and the opening and closing of the button cap 1 and the button body 2 do not generate friction, and are not easy to deform, which makes the button have a longer service life.
[0021] Reference Figure 1Furthermore, the outer side surface of the protrusion 251 is an arcuate surface 2511. When the protrusion 251 protrudes from the notch 221 to the outer side wall of the boss 22, the arcuate outer side surface extends from the bottom of the notch 221 to the top surface of the protrusion 251, so that when the boss 22 penetrates into the groove 111, the protrusion 251 is pressed by the side wall of the groove 111 and automatically shrinks. When the protrusion 251 moves to the position of the slot 112, the protrusion 251 acts on the swing arm 25 through the spring 253, and automatically pops out and snaps into the slot 112, so that when the button body 2 is buckled into the button cap 1, there is no need to operate the control handle 27 to swing the swing arm 25, which is more convenient to use.
