The invention discloses an elevator safety clamp wedge block. The elevator safety clamp wedge block comprises a wedge block body and a guide rail sweeping device. The lower portion of the guide rail contact face of the wedge block body is downwards concaved, and the upper portion is a braking face. The guide rail sweeping device comprises a retainer, a spring and a tooth-shaped shoe. The retaineris fixed to the downward concave position of the lower portion of the guide rail contact face of the wedge block body. A bottom plate of the tooth-shaped shoe is clamped to the retainer. The tooth face of the tooth-shaped shoe upwards gets out of the retainer and is higher than the braking face. The spring is placed between the bottom plate of the tooth-shaped shoe and the downward concave position of the lower portion of the guide rail contact face of the wedge block body. According to the elevator safety clamp wedge block, when a safety clamp acts, oil dirt on the surface of a guide rail iseffectively swept, the guide rail face making contact with the braking face of the wedge block is swept, and the braking stability of the safety clamp is enhanced.
