BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the high stability spring of the utility model.

[0014] Figure 2 The utility model is an exploded view of a keyboard switch. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below in conjunction with the embodiments.

[0016] refer to Figure 1 The utility model provides a high-stability spring, including a spring body 1 formed by spirally winding a single spring wire in sequence. The spring body 1 is a circular spiral structure, the spiral direction is right-handed, and a first stabilizing portion 11 and a second stabilizing portion 12 are respectively provided at both ends. The cross section of the spring body 1 is a circular ring. The cross section 13 of the spring wire is square, which can increase the contact area between adjacent spring coils, avoid sliding of adjacent spring coils when pressed, and improve the stability of the spring body 1.

[0017] The first stabilizing portion 11 and the second stabilizing portion 12 are arranged parallel to each other. The first stabilizing portion 11 is formed by bending the starting end of the spring wire and forming two tightly spirally connected first rings. The second stabilizing portion 12 is formed by bending the terminal end of the spring wire and forming two tightly spirally connected second rings. The first stabilizing portion 11 and the second stabilizing portion 12 are provided to improve the overall support performance of the high-stability spring and make it more stable. The first ring and the second ring have the same structure and are both the same shape and size as the ring.

[0018] Example 2

[0019] refer to Figure 2 This embodiment provides a keyboard switch, including a base 2, a handle 3, an upper cover 4 and a high-stability spring 5.

[0020] The base 2 is provided with a hollow fixed column 21, the handle 3 is provided with a limiting column 31, the bottom end of the high stability spring 5 is sleeved outside the fixed column 21, and the second stabilizing portion 12 is in contact with the base 2.
