The invention relates to a rock climbing safety auxiliary device, which comprises a T-shaped sleeve, a screw rod arranged in the T-shaped sleeve, and a nut sleeved on the top of the screw rod. The screw rod is provided with grooves for accommodating staples, The ball hinge seat, spring, and T-shaped sleeve are provided with a hole for the staple to pass through. When in use, the climbing safety auxiliary device is inserted into a suitable rock seam, the nut is rotated, the screw rises, and the staple is released from the T-shaped The hole of the sleeve goes out, and then gets stuck on the inner wall of the rock crevice. The ball hinge seat and the spring can slide in the groove on the screw rod, so as to ensure that as many pitons as possible are clamped. The device can effectively guarantee the safety of rock climbing and prevent accidents from happening.
