As shown in the figure, a structure of a buckle includes a connecting member 10, an elastic body 20, a limiting piece 30 and a connecting seat 40. A connecting member 10 defines a receiving slot 11 for receiving An opening edge 12 is formed at one end of the connecting member 10, and a groove bottom portion 13 is formed at a bottom end of the receiving groove 11. An elastic body 20 is integrally bent by a metal wire, and the elastic body 20 is formed at a middle portion thereof. There is a fixed section 21, and the elastic body 20 is bent at two right sides of the fixed section 21 with two elastic segments 22, and a head 23 is formed at the end of the elastic section 22, and the elastic body 20 is disposed on the fixed section 21 A limiting piece 30 is formed in a strip shape to form a stopping portion 31, and two supporting portions 32 are extended in the same direction on both sides of the stopping portion 31. The limiting piece 30 is pressed. The receiving groove 11 of the connecting member 10 is inserted into the receiving portion 11 of the elastic member 20 with the blocking portion 31, and the supporting portion 32 is pressed. The inner wall of the receiving groove 11 is formed to form a stable connection between the elastic body 20 and the connecting member 10, wherein the two supporting portions 32 of the limiting piece 30 face the bottom portion 13 of the receiving groove 11 to allow the top support portion 32 pairs of accommodating grooves 11 are formed in the forward direction, or as shown in FIGS. 4 and 5, the two struts 32 of the limiting piece 30 face the opening edge 12 of the accommodating groove 11, so that the struts 32 are opposite. The accommodating groove 11 is formed in a reverse direction to achieve an equal fixing effect, and the stopper portion 31 of the limiting piece 30 has a U-shaped or a W-shaped cross section, and can be improved by both the U-shaped and the W-shaped type. The contact area of the elastic body 20 makes the elastic body 20 less likely to sway. Referring to FIG. 6, the support portion 32 of the limiting piece 30 is formed in a zigzag shape, and as shown in FIG. 7, the limit piece is formed. The top support portion 32 of the 30 is formed with a side strip 33 and is vertically opposed to the receiving groove 11 by the side strip 33. The inner wall is further configured to improve the bonding strength between the connecting member 10 and the limiting piece 30 by using the structure of the limiting piece 30 having the zigzag and the everted edge strip 33, thereby achieving the effect that the connecting member 10 and the elastic body 20 are not easily separated. Further, at both ends of the limiting piece 30, a tapered portion 34 is formed by the stopping portion 31 toward the supporting portion 32, and the elastic portion 22 of the elastic body 20 is evaded by the chamfered portion 34, thereby increasing the limit. The connecting area of the connecting piece 40 and the connecting piece 10 defines a slot 41. The through-slot 41 defines a latching opening 42 on both sides of the connecting base 40. The connecting seat 40 is sleeved by the slot 41. The elastic body 20 has the head portion 23 of the elastic body 20 protruding from the fastening opening 42 of the coupling seat 40, thereby forming a quick engagement function of the coupling seat 40 and the coupling member 10.

According to still another embodiment of the present invention, the structure of the buckle is as shown in FIGS. 8 and 9. The structure includes a connecting member 10, an elastic body 20 and two limiting pieces 30, and a connecting piece. An accommodating groove 11 is formed in the through hole. The accommodating groove 11 defines an opening edge 12 at one end of the connecting member. An elastic body 20 is integrally bent by a metal wire. A fixing portion 21 is formed at a middle portion of the elastic body 20. And the elastic body 20 is formed with a second elastic portion 22 at right angles on both sides of the fixing portion, and a head portion 23 is formed at the end of the elastic portion 22, and the elastic body 20 is disposed in the receiving groove 11 by the fixing portion 21, The two limiting pieces 30 are formed with a blocking portion 31 in a strip shape, and two supporting portions 32 are extended in the same direction on both sides of the blocking portion 31, and the limiting piece 30 is pressed into the capacity of the connecting member 10. The groove 11 is disposed, and the fixing portion 21 of the elastic body 20 is interposed between the stopper portions 31 of the two limiting pieces 30, thereby forming a stable connection between the elastic body 20 and the connecting member 10, thereby achieving easy assembly and effectively reducing the production thereof. Cost, and the effect of reducing the volume

The effect of the actual use is as shown in FIG. 1 to the seventh figure. The connecting member 10 and the connecting seat 40 are used for connecting the two ends of the belt body (not shown), and the elastic body 20 The opening edge 12 is placed in the receiving groove 11 of the connecting member 10, and the limiting piece 30 is placed in an extruded manner. The accommodating groove 11 is in contact with the fixing portion 21 of the elastic body 20 by the blocking portion 31 of the limiting piece 30, and then the struts 32 of the limiting piece 30 are externally supported against the inner wall of the accommodating groove 11, The fixing portion 21 of the elastic body 20 is limited to the bottom portion 13 of the groove of the connecting member 10, so that the elastic portion 22 of the elastic body 20 partially passes through the opening edge 12 of the receiving groove 11, and the exposed portion 23 of the elastic body 20 is formed. When in use, the head 23 of the elastic body 20 forms an internal pressure with the elastic force of the elastic section 22, and can directly insert the head 23 into the slot 41 of the coupling seat 40, and the head 23 is convex by the elastic force of the elastic section 22. The fastening opening 42 of the connecting seat 40 can thereby achieve the quick coupling of the connecting member 10 and the connecting seat 40, and can be quickly disassembled. With the structure of the above specific embodiment, the following benefits can be obtained: the elastic body The fixing portion 21, the elastic portion 22 and the head portion 23 are integrally formed by the metal wire, and the limiting piece 30 is integrally formed with the stopping portion 31 and the supporting portion 32, and the elastic body 20 is placed in the fixing portion 21. The connecting member 10 receives the slot 11 and is pressed into the receiving slot 11 by the limiting piece 30, so that the blocking portion 31 of the limiting piece 30 abuts the fixing portion 21, and Bit 30 of the top sheet supporting portion 32 accommodating the inner wall of the compression chamber 11, so as to achieve easy assembly and reduce its production costs, even take effect with a reduced volume, serve to enhance its usefulness.

In summary, the present invention has indeed achieved a breakthrough structural design, and has improved invention content, and at the same time, can achieve industrial utilization and progress, and the present invention is not found in any publication, but also novel, when In accordance with the provisions of the relevant laws and regulations of the Patent Law, the application for invention patents is filed according to law, and the examination authority of the bureau is required to grant legal patent rights.
