Abstract

The invention provides an automobile spare tire fixing device, which comprises a support frame (1), clamp arms (3), a center shaft (2), a chuck (7), a clamp lock (8), an opening knob (9) and a stay wire (10), and is characterized in that the clamp arms (3) are rotated by the center shaft (2) to do gear rack movement, so that the clamp arms clamp a spare tier; the chuck (7) is fixed on the center shaft (2), a limit mechanism is utilized to realize one-way rotation of the center shaft so as to realize self-lock function by the clamp lock (8); the opening knob (9) is connected by the stay wire (10), so that the clamp lock limit mechanism is failed, and the aim of disassembling the spare tier is achieved. According to the automobile spare tire fixing device, the oppositely arranged clamp arms are adopted as a clamping device, so that the spare tire can be installed quickly in a labor-saving way; in addition, the tire can be tightly clamped effectively without being loosened easily; the clamp arms can be used for clamping other objects within the range according to the customer demands, and are also attractive and practical.
