The invention discloses a novel embedded wire winding mechanism based on a 3D printing technology. The novel embedded wire winding mechanism comprises a supporting framework, a first motor, a wire spool, a first mounting plate, a mounting framework, a fixing block, a worm, supporting legs, a base, a first bearing seat, a fixing plate, a worm gear, a first fixing seat, a first belt, a second bearing seat, a second belt, a second mounting plate, a second sliding block, springs, a second motor and a second fixing seat. According to the novel embedded wire winding mechanism based on the 3D printing technology, clamping arms are driven to move along second fixing rods through elastic force of springs, the distance between the clamping arms can be adjusted according to the thickness of a wire rod, the worm and gear are rotated to drive a second lead screw to move in the vertical direction of the fixing block, and therefore, the distance between a first conical head and a second conical headis adjusted, and rapid mounting and fixation of the wire spool is realized; and most parts of the wire spool are produced with the 3D printing technology, the weight and the production cost of the device are greatly reduced, and meanwhile, the maintenance and replacement efficiency is improved.
