Abstract

The present invention relates to a rod-climbing protector. A protector 30 is arranged on a safety belt. The protector is divided into a left hand and a right hand which are used in pairs. A protector body 1 is connected with a clamp arm 3, a lock hook 9, shifting fork 6, a lacing wire 20, a four-finger holding handle 2, a clamp mouth rod 34 and a clamp mouth plate 35. The clamp mouth rod is connected with a support rod shaft 50 and the clamp mouth plate is connected with a clamp mouth shaft 12. When people work on a rod tower, the rod-climbing protector can be put on the hands. Under the mutual action of the lacing wire, the four-finger holding handle and the clamp arm, the protector can keep one closed and the other open. One protector always exists in closed state, and the personal safety can be ensured. The present invention has the advantages of low cost, easy use, etc.
