Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model provides an in, knife rest is cut out to wire cord fabric, including the knife rest 4 that is used for fixed cut-off knife 5, through the supporting seat 2 that pivot 3 links to each other with knife rest 4, plays limiting displacement's connecting piece 6 and the elastic component 7 that is used for fixing a position the knife rest to the knife rest.

The utility model discloses a tool rest, including knife rest, fixing piece, supporting seat, connecting piece, knife rest both sides all are provided with mounting 1, mounting and supporting seat fixed connection, waist shape hole 10 has been seted up on 4 surfaces of knife rest, the connecting piece runs through two mountings and passes waist shape hole, the rotating angle of knife rest is injectd through the mode that passes the knife rest to the connecting piece, simultaneously under the effect in waist shape hole 10, can also inject the rotation orbit of knife rest. Knife rest both ends fixedly connected with is used for the elastic component 7 fixed to knife rest fastening, in this embodiment, elastic component 7 can be the spring, and when elastic component 7 was the spring, the spring need overlap and establish on the connecting piece and the position is located respectively between connecting piece and two mountings, the spring is compression state, and knife rest relative supporting seat 2 was fixed this moment, and only when the knife rest received external force to promote, the position just can relative connecting piece change.

All set up the elastic component, two between knife rest both ends and two mountings the elastic component is the same and symmetrical about the knife rest for the cut-off knife on the knife rest is in the state of placing in the middle under free state, avoids cutting initial position askew partially and causes the exposure steel wire, to a certain extent, has improved the precision that this device cut to the wire cord fabric in the use.
