Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1 to 3. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

In order to describe the present invention in detail, first, the spring clip of the present invention will be described in detail as follows:

please refer to fig. 1 to 3, the utility model provides a spring buckle, including base 3, spring 2 and main shaft 1, the spring hole of spring 2 with main shaft 1 phase-match, spring 2 cover is established on main shaft 1 promptly, and spring 2 can use the axis of main shaft 1 to rotate as the axle, base 3 includes two at least draw-in grooves 31, at least two the extending direction of draw-in groove 31 is crossing, the one end of spring 2 with base 3 is connected, the other end 21 of spring with draw-in groove 31 phase-match, through removing the other end 21 of spring from draw-in groove 31, realize the rotation of spring 2, then move the other end 21 of spring into draw-in groove 31, realize spring 2's spacing.

Preferably, the clamping grooves 31 are U-shaped grooves, the number of the clamping grooves 31 is two, the extending directions of the two clamping grooves 31 are perpendicular to each other, the processing difficulty is reduced, and the limiting and rotating efficiency of the spring is improved.

Referring to fig. 3, two clamping grooves are defined as a first clamping groove and a second clamping groove, the first clamping groove is matched with the spring, the first clamping groove includes a first limiting arm 311 and a first second limiting arm 312, the second clamping groove includes a second limiting arm 313 and a second limiting arm 314, the first second limiting arm 312 is connected with the second limiting arm 314, the first limiting arm 311 and the second first limiting arm 313 are arranged in a separated manner, and the second limiting arm 313 is forced to generate elastic deformation by external force, so that the limiting and moving-out of the spring wire 33 are realized.
