The invention relates to a hand strap speed measuring device with an automatic adjusting function. The hand strap speed measuring device comprises a hand strap provided with a fixing support. The fixing support is in an L shape, one end of the fixing support is fixedly connected with a speed measuring pressing wheel, and the other end of the fixing support is fixedly connected to an escalator support installation plate. A spring is fixedly connected to the support installation plate. The speed measuring pressing wheel presses the hand strap, a V-shaped groove is formed in the middle of the speed measuring pressing wheel, and the spring is a parallel two-torsion spring. Compared with the prior art, the hand strap speed measuring device has the beneficial effects that through the speed measuring pressing wheel and the parallel two-torsion spring, the phenomenon that the edge of the hand strap is loosened and tightened when an escalator operates to a large height is avoided.
