[0025] The words "first", "second" and the like in the terminology of the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be construed as limiting the order of precedence.

[0026] The utility model provides a spring piece, including a long arm 11 and an elastic arm connected to the long arm 11, the long arm 11 is provided with a symmetrical strip through hole 112, the elastic arm includes a plurality of elastic arms 12 respectively connected to the two ends of the strip through hole 112, the elastic arm 12 and the long arm 11 are integrally formed, the elastic arms 12 at the two ends of the strip through hole 112 are mirrored, the elastic arms 12 are located at the two ends of the strip through hole 112, when the strip through hole 112 is punched on the long arm 11, the material punched out of the strip through hole 112 is cut off and bent toward the two ends of the strip through hole 112, so as to form the elastic arm 12, and the elastic arm 12 is integrally connected to the long arm 11, on the one hand, the elastic arm 12 integrated with the long arm 11 is stronger, and the elastic arm 12 is not easy to separate from the long arm 11, on the other hand, punching the elastic arm 12 on the long arm 11 can save assembly process, and the elasticity is more stable, which greatly increases the production efficiency.

[0027] The elastic arm 12 includes an elastic plate 121 connected to the long arm 11 and an elastic portion 122 connected to the elastic plate 121 . The elastic plate 121 is used to facilitate resetting the elastic portion 122 and for the elastic portion 122 to press against an object.

[0028] The spring plate 121 is L-shaped, and the L-shaped spring plate 121 is convenient for bending and resetting, so that the elastic part 122 is in closer contact with the contact object.

[0029] The elastic portion 122 includes an extension plate 1221 connected to the elastic plate 121 and a contact plate 1222 connected to the extension plate 1221. The extension plate 1221 is inclined, and the angle between the extension plate 1221 and the elastic plate 121 is an acute angle. The contact plate 1222 and the extension plate 1221 are L-shaped. The contact plate 1222 is used to connect to a contact object, and the extension plate 1221 is used to extend the distance between the contact plate 1222 and the elastic plate 121 to prevent the distance between the contact plate 1222 and the contact object from being too small.

[0030] The long arm 11 is also provided with a plurality of symmetrical mounting holes 111 . The mounting holes 111 are located between the symmetrical bar-shaped through holes 112 . The mounting holes 111 are used to conveniently fix the long arm 11 on the product.

[0031] Working principle:

[0032] When the spring sheet is punched, first, the long arm 11 is placed on a punching machine, and the punching machine punches out the shape of a strip through hole 112 on the long arm 11. The material of the strip through hole 112 is connected to the long arm 11, and the material of the strip through hole 112 is bent into an L shape to form a spring plate 121. The spring plate 121 is bent again to form an inclined extension plate 1221, so that the extension plate 1221 and the spring plate 121 are at an acute angle. Finally, the extension plate 1221 is bent again to form a contact plate 1222. The contact plate 1222 and the extension plate 1221 are L-shaped, so that the elastic arm 12 and the long arm 11 are integrally formed, which not only increases the hardness of the elastic arm 12 and the long arm 11, making the elastic arm 12 and the long arm 11 not easy to separate, but also omits multiple installation steps, effectively improving the processing efficiency.

[0033] In the preferred embodiment of the spring piece of the present invention, after the strip-shaped through hole is punched on the long arm, the material of the strip-shaped through hole is not separated from the long arm, and the material of the strip-shaped through hole is bent to form an elastic arm. The elastic arm and the long arm are formed in one piece. On the one hand, it can effectively ensure the strength of the elastic arm and the long arm, so that the elastic arm is not easily separated from the long arm. On the other hand, it omits multiple installation steps, and there is no need to re-process the elastic arm and then fix the elastic arm on the long arm, thereby effectively improving processing efficiency.

[0034] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
