The invention provides a multi-directional clamping type steel tube cutting and delivering device for solving the technical problem that a steel tube cannot be delivered forwards in a fixed-interval way in a steel tube cutting process. The multi-directional clamping type steel tube cutting and delivering device comprises a fixed-length delivery guide rail, a fixed-length clamping and mounting frame, a clamping mechanism, a bidirectional synchronous clamping driving connecting mechanism, a fixed-length clamping and jacking mechanism, a lifting mechanism, a clamping movable tray mechanism and a bottom frame; two sides, symmetrically mounted at the outer end of the fixed-length clamping and mounting frame, of the clamping mechanism pass through the bidirectional synchronous clamping driving connecting mechanism; the fixed-length clamping and jacking mechanism is fixedly mounted on an upper cross plate of the fixed-length clamping and mounting frame; the lifting mechanism is fixedly mounted on a base plate of the fixed-length clamping and mounting frame; a movable tray is mounted at the bottom of the fixed-length clamping and mounting frame; and a bracket device can also be mounted behind the fixed-length delivery guide rail. The multi-directional clamping type steel tube cutting and delivering device provided by the invention has the beneficial effect of realizing fixed-interval delivery of the steel tube in the steel tube cutting process.
