[0006] In some embodiments, the head support section is provided with two tightly spirally connected first rounded rectangle rings, and the tail support section is provided with two tightly spirally connected second rounded rectangle rings.

[0007] In some embodiments, the spiral direction of the spring coil body is right-handed.

[0008] In some embodiments, the cross-section of the spring coil body is a rounded rectangle ring, which has the same shape and size as the first rounded rectangle ring and the second rounded rectangle ring.

[0009] According to another aspect of the utility model, a keyboard switch, a base, an actuator handle, an upper cover and a square spring are provided. The base is provided with a hollow fixing column. The square spring is sleeved outside the fixing column, and the tail support section abuts against the base.

[0010] In some embodiments, the upper cover is disposed on the base, the pressing handle is provided with a limiting post, the pressing handle passes through the upper cover, the limiting post is inserted into the fixing post and the square spring, the first supporting section abuts against the pressing handle, and the square spring is sleeved outside the limiting post.

[0011] The beneficial effects of the present utility model: By setting the cross-section of the spring to be a rounded rectangular ring, the stability of the spring is improved, and it will not be skewed or rotated during the downward movement, thereby improving the knocking and rebounding feel of the keyboard and the user's operating feel. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic structural diagram of the square spring of the present utility model.

[0013] Figure 2 It is a schematic structural diagram of the rounded rectangular ring of the square spring of the present utility model.

[0014] Figure 3 It is an exploded view of a keyboard switch of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

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

[0016] Reference Figures 1 to 2 , the present utility model provides a square spring, which includes a spring coil body 1 sequentially formed by helically winding a single spring wire. The spring coil body 1 is a helical structure of a rounded rectangle, the helical direction is right-handed, and its two ends are respectively provided with a first supporting section 11 and a tail supporting section 12. The cross-section of the spring coil body 1 is a rounded rectangular ring 13.

[0017] The first supporting section 11 and the tail supporting section 12 are arranged parallel to each other. The first supporting section 11 is two closely helically connected first rounded rectangular rings formed by curling the head end of the spring wire. The tail supporting section 12 is two closely helically connected second rounded rectangular rings formed by curling the tail end of the spring wire. The setting of the first supporting section 11 and the tail supporting section 12 can improve the overall supporting performance of the square spring and make it more stable. The structures of the first rounded rectangular ring and the second rounded rectangular ring are the same, and are both the same in shape and size as the rounded rectangular ring. The shapes of the first rounded rectangular ring and the second rounded rectangular ring are set to be rounded rectangles, so that the contact surfaces at the top and bottom of the square spring are changed from the common circles to rounded squares, making the spring coil body 1 more stable during the pressing and rebounding process and not prone to rotation and skew.

[0018] Embodiment 2

[0019] Reference Figure 3 , this embodiment provides a keyboard switch, which includes a base 2, a pressing handle 3, an upper cover 4 and a square spring 5.

[0020] The base 2 is provided with a hollow fixing post 21, the pressing handle 3 is provided with a limiting post 31, the bottom end of the square spring 5 is sleeved outside the fixing post 21, and the tail support section 12 abuts against the base 2. The upper cover 4 is covered on the base 2, the pressing handle 3 passes through the upper cover 4, the limiting post 31 is inserted into the fixing post 21 and the square spring 5, the head support section 11 abuts against the pressing handle 3, and the top end of the square spring 5 is sleeved outside the limiting post 31.

[0021] The cross-sectional shape of the square spring 5 of the present utility model is a rounded rectangle, and its pressing stability is greatly improved compared with the existing circular spring, especially in the application environment of a keyboard that is frequently compressed and rebounded for a long time. When the keyboard is struck, the square spring 5 is compressed, and it moves downward more stably without skewing or rotating during the downward movement, improving the striking and rebounding feel of the keyboard.

[0022] Therefore, the square spring 5 of the present utility model is applied to the keyboard, which can better meet the usage requirements of the keyboard when it is struck multiple times, and can maintain a good striking and rebounding feel of the keyboard during use, improving the user's operation feeling.

[0023] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
