Description

Supporting foot stand

Technical Field

The invention relates to a support leg frame, in particular to a support member pivoted on a seat body, which can make a fixing member rotate through at least two pressing actions so as to drive a locking mechanism to generate circular sliding and positioning through the fixing member, thereby facilitating the rapid opening of the support member for supporting action, and the support member can be rapidly folded into the seat body through the second pressing action and is matched with the clamping and positioning of the fixing member to be in a closed state.

Background

Generally, an input device used in an electronic device such as a desktop computer or a notebook computer includes a keyboard, a mouse, a touch pad or an optical scanner, however, in order to input a text or a command rapidly, the most commonly used input device is a keyboard and a touch pad, and the keyboard is mainly composed of a plurality of keys arranged and combined, and includes: letter keys, number keys, function keys and other keys, so that the keyboard can be used for inputting characters or instructions, the touch pad can be used for inputting corresponding data to a computer after the instructions are identified in a handwriting mode, and the input devices are placed on a plane for use, and for the input devices needing to be placed at a special inclination angle, for example: in order to make the keyboard comfortable in use, a supporting leg is usually disposed at the bottom of the keyboard, and the supporting leg can be folded or rotated out from the keyboard to be in a supporting state, so as to provide a comfortable operation angle for a user and facilitate input.

However, when the present supporting foot stand is used, the foot stand needs to be rotated to stand by pulling the foot stand with a hand, but in the process of positioning the supporting foot stand, most supporting foot stands only use the rotating shaft as an axis to rotate relatively so as to achieve the purpose of pulling the foot stand to form an angle, so that a user always needs to consume large strength to pull the foot stand to be positioned, and if the user pulls the foot stand to apply too large force or the angle is not correct, the rotating shaft can deform and skew, so that the subsequent opening or folding process is not easy to perform, and the supporting foot stand can not be used even if the supporting foot stand is broken or damaged after being used for a long time.

Therefore, how to try to solve the above-mentioned existing drawbacks and inconveniences is a direction that the related art needs to research and improve.
