Description
Technical field
The utility model relates to the mechanism on a kind of paper cutter, is specifically related to a kind of tool rest pull bar that is used for paper cutter.
Background technology
Existing paper cutter generally includes the tool rest of frame, heap paper platform, gear-box and fixed blade.Wherein tool rest is connected on the tool rest pull bar, and the other end of tool rest pull bar is connected on the gear-box.The tool rest pull bar constitutes (see figure 1) by left and right threaded rod 1,3, adjustment nut 2, elastic cylindrical pin 4 etc.The tail end of left and right threaded rod 1,3 has draw- bar seat 10,30 respectively; The draw-bar seat 30 of the tail end of right-hand thread bar 3 connects through screw gate 5.Adjustment nut 2 is a rectangle frame; Offer a tapped through hole respectively on two relative edges of adjustment nut 2; Left and right threaded rod 1,3 is threaded in respectively on the tapped through hole of adjustment nut 2. and the cutter cutting-in degree of paper cutter is to come the length of adjusting yoke to realize by rotation adjustment nut 2, just will regulate the draw-bar seat 10 on the left and right threaded rod 1,3, the distance between 30.The pull bar of existing structure is when lengthening length; Normally rotate left-hand thread bar 1; The draw-bar seat 10 that makes left-hand thread bar 1 is away from adjustment nut 2, owing to only depend on elastic cylindrical pin 4 spacing after in the cavity of the other end precession adjustment nut 2 of left-hand thread bar 1, when left-hand thread bar 1 is twisted when excessive; Make elastic cylindrical pin 4 fractures easily, damage left-hand thread bar 1 and adjustment nut 2.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of tool rest pull bar that is used for paper cutter to be provided, and it can be avoided when the tool rest pull bar lengthens, overstepping the extreme limit and make the damage of left-hand thread bar and adjustment nut.
The technical scheme that realizes above-mentioned purpose is: a kind of tool rest pull bar that is used for paper cutter; Comprise left and right threaded rod and adjustment nut; Said adjustment nut is a rectangle frame; Offer one on the left and right edge of this adjustment nut respectively and be respectively applied for the tapped through hole that connects said left and right threaded rod, wherein:
Offer a tapped blind hole on the head end of said left-hand thread bar, this left-hand thread bar is screwed in the left-hand thread hole of said adjustment nut;
Offer on the inner surface of the left edge of said adjustment nut one with the coaxial groove in said left-hand thread hole;
Said tool rest pull bar comprises also that the right-hand thread hole on a width and the said adjustment nut is adaptive, the adaptive locking gasket that is waist shape of groove diameter on length and the said adjustment nut; This locking gasket is gone into the cavity of said adjustment nut and behind half-twist, is fixed on the head of said left-hand thread bar through a screw from the right-hand thread stopple of said adjustment nut, so that locking gasket can be embedded in the groove of said adjustment nut.
The above-mentioned tool rest pull bar that is used for paper cutter wherein, is offered the adaptive blind hole of spiral shell head external diameter of a diameter and said screw on the head end of said right-hand thread bar.
The technical scheme of the tool rest pull bar that is used for paper cutter of the utility model; Increase by a locking gasket through head, when the tool rest pull bar is lengthened, screw out with overstepping the extreme limit by locking gasket restriction left-hand thread bar at the left-hand thread bar; Overcome existing tool rest pull bar because elastic cylindrical pin contacts with the line of adjustment nut; Make the damage of left-hand thread bar and adjustment nut easily, change locking gasket into and contact, eliminated the phenomenon of left-hand thread bar with the easy damage of adjustment nut with the face of adjustment nut.
Description of drawings
Fig. 1 is the structural representation of the tool rest pull bar that is used for paper cutter of prior art;
Fig. 2 is the structural representation of the tool rest pull bar that is used for paper cutter of utility model;
Fig. 3 is the structural representation of the tool rest pull bar locking gasket that is used for paper cutter of utility model.
The specific embodiment
In order to understand the technical scheme of the utility model better, below through embodiment particularly and combine accompanying drawing at length to explain:
See also Fig. 2 and Fig. 3, a kind of tool rest pull bar that is used for paper cutter of the utility model comprises left and right threaded rod 1 ', 3 ', adjustment nut 2 ' and locking gasket 6.Wherein:
Adjustment nut 2 ' is a rectangle frame; Offer one on the left and right edge of this adjustment nut 2 ' respectively and be respectively applied for and connect left and right threaded rod 1 ', 3 ' tapped through hole, offer a groove 20 coaxial on the inner surface of the left edge of this adjustment nut 2 ' with said left-hand thread hole;
The tail end of left-hand thread bar 1 ' has draw-bar seat 10, offers a tapped blind hole on the left-hand thread bar 1 ' head end, and this left-hand thread bar 1 ' is screwed in the left-hand thread hole of adjustment nut 2 ';
The tail end of right-hand thread bar 3 ' has draw-bar seat 30, offers a blind hole 31 on the head end of right-hand thread bar 3 ';
This locking gasket 6 is gone into to adjust the cavity of nut 2 ' and behind half-twist, is fixed on the head of left-hand thread bar 1 ' through a screw 7 from the right-hand thread stopple of adjustment nut 2 '.
When assembling; Earlier left-hand thread bar 1 ' is screwed into adjustment nut 2 '; The spiral shell head of left-hand thread bar 1 ' must be screwed to the inner surface that exceeds the left edge of adjusting nut 2 '; The right-hand thread stopple of locking gasket 6 from adjustment nut 2 ' advanced to adjust the cavity of nut 2 ',, with screw 7 locking gasket 6 is fixed on the head of left-hand thread bar 1 ' again locking gasket 6 half-twists; And then in the right-hand thread hole with right-hand thread bar 3 ' screw-in adjustment nut 2 ', the draw-bar seat 30 of the tail end of right-hand thread bar 3 ' connects through screw gate 5.
When the tool rest pull bar of the utility model that will lengthen, when left-hand thread bar 1 ' outwards was screwed into the limit, locking gasket 6 can be embedded in the groove 20 of adjustment nut 2 '.In the time will shortening the tool rest pull bar, when left-hand thread bar 1 ' inwardly was screwed into the limit, the spiral shell head that is used for fixing the screw 7 of locking gasket 6 can get in the blind hole 31 of right-hand thread bar 3 ', and did not influence the shortening stroke of tool rest pull bar.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
