Detailed description of the invention

The utility model is described in detail below in conjunction with accompanying drawing 1.

With reference to accompanying drawing 1, a kind of tie disc device, comprise base 1, base 1 is fixed with bearing seat 2, bearing 3 in bearing seat 2 is supported with rotating shaft 4, rotating shaft 4 left end is connected with reducing motor 5, rotated by reducing motor 5 drive shaft 4, rotating shaft 4 shaft shoulder is connected with inner casing 6, be provided with outside inner casing 6 and be no less than two hinged mouths, each hinged mouth is hinged by bearing pin 8 and breathing plate 7 one end, and breathing plate 7 other end is hinged by bearing pin 8 and carrier bar 9 one end, and carrier bar 9 other end is hinged with the hinged mouth above swivel nut 10 by bearing pin 8; Swivel nut 10 inside face is provided with keyway, and swivel nut 10 is slided by the feather key 14 in rotating shaft 4 but do not rotate in rotating shaft 4; Swivel nut 10 is also connected with the outside thread of screw rod 11 by inside face screw thread, and screw rod 11 one end is socket cap, and socket cap embeds in the blind hole at rotating shaft 4 right-hand member center, and makes screw rod 11 rotate but not be moved by baffle plate 13 constraint; Screw rod 11 other end is furnished with handle 12 interface, by rotary handle 12, screw rod 11 rotating band movable snail sleeve 10 is moved forward and backward, thus drive carrier bar 9 to move and the corner dimension changed between carrier bar 9 and breathing plate 7 realizes breathing function, complete and the support of tie is fixed.Outer casing 15 is connected with the outside thread of swivel nut 10 by the negative thread at center, the both ends of the surface of tie is fixed between inner casing 6 and outer casing 15.Drive whole tie disc to rotate eventually through reducing motor 5 drive shaft 4, complete the uncoiling of tie.

Described bearing, reducing motor, bearing pin and handle are common gauge member.

The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.

Breathing plate 7 must be located at outside inner casing 6 with the articulated position of inner casing 6, and is no less than two.
