The utility model discloses a corrugated high-temperature-resistant cable protection tube, which belongs to the technical field of cable protection tubes and comprises an inner tube body, and a honeycomb tube body is wrapped on the outer wall of the inner tube body. The outer pipe body wraps the side, away from the inner pipe body, of the honeycomb pipe body, a corrugated pipe body is spirally wound on the outer wall of the outer pipe body, air holes are formed in the corrugated pipe body, flange rings are arranged at the two ends of the outer pipe body, and mortises are formed in the sides, away from each other, of the flange rings. Through the arrangement of the corrugated pipe body matched with the arrangement of the honeycomb pipe body, the overall pressure resistance of the cable protection pipe can be greatly improved, and meanwhile through the auxiliary improvement of the buffering effect, the impact resistance effect of the pipe body is further improved, so that the ring stiffness of the cable protection pipe is further improved, and the service life of the cable protection pipe is prolonged. And the situation that the pipe body is pressed to deform or crack due to insufficient ring stiffness is effectively reduced.

This utility model discloses a flat-jaw vise with accurate positioning and high positioning precision. The lower end of the fixed jaw is fixedly installed on one end of the base, and the support of the pushing mechanism is slidably and fixedly installed on the base. The lower end of the movable jaw clamping block is slidably installed on the base, with a movable jaw fixed at one end and a mounting hole at the upper end and a threaded hole I at the lower end of the other end. A steel ball mounting groove is formed on the U-shaped groove wall near the movable jaw. The upper surface of the L-shaped angle block is provided with an inclined surface, which is placed in the U-shaped groove of the clamping block. Its lower end is slidably installed on the base, and its inclined surface presses against the steel ball. A set screw threaded into the threaded hole I of the clamping block is pressed against the end face of the L-shaped angle block away from the movable jaw. The lead screw passes through the mounting hole of the clamping block and abuts against the end face of the L-shaped angle block away from the movable jaw. This utility model has a good inclined pressing effect, accurate positioning, good stability, and high positioning precision, which can meet the needs of high-precision machining of workpieces.
