Abstract

The invention is a device for holding and releasing a screw comprising a main body which is made by elastic material in one unity. The main body comprises a fixing portion which covers in a screwdriver. The fixing portion has an axle hole which passes the top end through the bottom end. The axle hole is used for the connecting rod and the drill of the screwdriver passing through. Each of the two sides of the bottom end of the fixing portion extends a base portion which is gradually distant from the axle of the axle hole. Between the radial extension line of the two base portions and the axle of the axle hole has a first included angle which is larger than zero, and each of the end of the base portions extends inward to form a clamping bar which is gradually to approach the axle of the axle hole. Between the bas portion and inner face of each of the clamping bar which extends from the base portion forms a second included angle which is larger than 90 degrees, and the base portion and the curve position of the clamping bar with elasticity can be curved and deformed. The end of each of the clamping bar extends outward to form a lip edge which is gradually distant from the axle of the axle hole to make that each of the inner face of the lip edge opposite to the inner face forms a spreading guiding face to assist the screwdriver holding or releasing the head of the screw more steadily. It improves the convenience of using the screwdriver in single hand and using in a narrow space, and also achieves the purpose of small volume, simplified structure, easy for carrying, and manufacturing in low cost.
