Description

Protective cover for power tongs Technical Field The utility model belongs to the technical field of protection, and particularly relates to a protective cover for power tongs. Background In the prior art, when the power tongs clamp an object, the power tongs and the object often lack effective protection, which may not only cause the object to be damaged in the clamping process, but also cause injury to operators. According to the protective cover (with the publication number of CN 210127840U) for the power tongs, the protective cover comprises two connecting blocks, two guide pipes and an arc plate, wherein the two connecting blocks are used for being fixedly connected with the side wall of a frame at the bottom of the power tongs, the two guide pipes are fixedly connected with the connecting blocks and are vertically arranged, guide sliding grooves are formed in the pipe wall of each guide pipe along the length direction of each guide pipe, the arc plate consists of an arc plate part and sliding limiting parts, the two sliding limiting parts are respectively arranged on two sides of the upper end of each arc plate part, the outer ends of the two sliding limiting parts are respectively arranged in one guide pipe, and the sliding limiting parts can freely slide along the guide sliding grooves.
