A safety tensioning device for automobile, comprising a main body (1), a winding mechanism (2) and a first strap (3); characterized in that, the winding mechanism (2) comprises a frame (21) having two opposite walls, a winding shaft (22) and a winding wheel (23); the winding shaft (22) runs through the two opposite walls of the frame (21), the winding wheel (23) is mounted on the shaft and disposed outside of the frame (21), and an inner end of the first strap (3) is connected to the winding shaft (22); when the winding wheel (23) rotates outward, the winding wheel (23) drives the winding shaft (22) to rotate synchronously so that the first strap (3) is wound onto the winding shaft (22) and inside the frame (21), and, when the winding wheel (23) rotates inward, the winding wheel (23) drives the winding shaft (22) to be locked to the frame (21), thus preventing the first strap (3) from unwinding. The present invention has the following advantages, in the safety tensioning device for automobiles with a manual winding function, the winding wheel can be rotated inward or outward. When the winding wheel is rotated outward, the winding shaft can be driven to rotate synchronously, so that the first strap is wound in the frame; and, when the winding wheel is rotated inward, the frame can be locked to prevent from rotation, so that the wound strap is prevented from loosening. In addition, the first strap passes through the device body and is limited on the band slot, so the strap can be prevented from being pulled out accidently.
