Clamping base

A clamping base for holding a camera and clamping an electronic device, comprising:

• a body with four lateral sides, having a pressing plate at the top thereof with an end of the pressing plate joined to a first of said lateral sides thereof for pressing and holding an elastic plate of the camera;
• a moving portion, being movably attached to a second of said lateral sides of the body, which is opposite to the first lateral side;
• and
• a first wall portion having a wallboard detachably engaging with the bottom of the body and extending downward;
• wherein, the moving portion further comprises:
• two sliding rods, each of the sliding rods being fixed to the moving portion at a first end thereof and being received in the body at a second end thereof;
• a second wall portion, extending downward from the moving portion opposite to the wallboard of the first wall portion;
• and
• an elastic element, surrounding each of the sliding rods respectively with an end thereof being fixedly joined to the second end of the respective sliding rod and another end thereof pressing against the second lateral side of the body;
• whereby, once the moving portion is pulled away the body by a user with the sliding rods and the second wall portion against elastic force of the elastic element, a distance is formed between the first wall portion and the second wall portion;
• and once the moving portion is stopped being pulled away the body, the electronic device is clamped by the second wall portion with the elastic force against the first wall portion.
