There are snaps seat 3, the second end of the blade 1 to be fixed on the snaps seat 3, fixed form can be removable to be carried out by screw
Unload it is fixed, the first end of the blade 1 is stretched out described outer by the first opening between being opened in two limit protrusions 21
Shell 2.The second end being fixed on snaps seat 3 is fixed the position of blade 1 so that the second end section of blade 1 is located at
In accommodating chamber in shell 2, shell 2 is stretched out in first end section, for cutting gummed paper.First end is located at two limit protrusions 21
Between, as previously mentioned, can prevent blade 1 from tilting under the limitation of two limit protrusions 21 and accidentally injure electric machine winding.
As a kind of preferable embodiment, the cutter further includes moulding component, and the moulding component is used for described
Squeeze the object before the first end cutting object of blade 1 and/or when cutting object, the cutter be mainly used for cutting motor around
During group, the gummed paper of winding is wrapped up, which can be the U.S. line paper of pressure sensitive, i.e., after being squeezed, can play good
Adhesive effect.Therefore setting moulding component can make the gummed paper and other gummed papers or coil good bond of cutting part, prevent
Gummed paper is fallen off, and coil is avoided to be scattered.
As a kind of preferable embodiment, the moulding component includes being at least partially disposed in the shell 2
Moulding paper 41 is provided with the gap that the blade 1 can be made to pass through in the moulding paper 41；Moulding paper 41 is preferred corresponding
It is arranged in snaps seat 3, the blade 1 on snaps seat 3 can at least partially penetrate in the gap in moulding paper 41, work as institute
When stating moulding paper 41 and being moved to the snaps seat 3, the blade 1 being fixed on the snaps seat 3 can run through the pressure
The first end of gummed paper head 41, blade 1 is stretched out by moulding paper 41, and squeezing the gummed paper in machine winding in moulding paper 41 is glued
After closing securely, gummed paper is cut.It is moved to the direction far from snaps seat 3 when moulding paper 41, the first end of blade 1 is received
It returns, can be accommodated in inside moulding paper 41, prevent the stretching of blade 1 from causing security risk, while can also prevent blade 1 from hindering pressure
Extrusion operation of the gummed paper head 41 to gummed paper.
As a kind of preferable embodiment, when the shell 2 includes accommodating chamber and the first opening, the moulding paper
First 41 include：Fixed part, the fixed part are set in the accommodating chamber of the shell 2, including can be with the accommodating chamber
The step structure that abuts against of inner wall；One end of moulding bar, the moulding bar is connected on the fixed part, and the other end is by described
First opening stretches out the shell 2, for contacting and squeezing gummed paper, increases gummed paper bonding force.On fixed part, the setting of moulding bar
In the homonymy of step structure.
As a kind of preferable embodiment, the moulding component further includes spring 42, and one end of the spring 42 abuts
In on the moulding paper 41, the other end is connected on the snaps seat 3, and blade 1 is stretched out by the hollow part among spring 42,
1 first end of blade can stretch into moulding paper 41.When in not used state, spring 42 can be at the state of not stressing,
Or it is slightly compressed, so as to which moulding paper 41 to be connected on the inner wall of accommodating chamber, so that the end of moulding bar is protruded from outer
The first end of shell 2, blade 1 can be accommodated in moulding bar；When in use, one end for protruding from shell 2 of moulding bar connects with gummed paper
Stress is touched, moulding paper 41 is pushed to the direction of snaps seat 3, compressed spring 42, and make the knife being hidden in moulding paper 41
The first end of piece 1 is exposed, and for cutting gummed paper, after the completion of cutting, cutter is lifted, due to the work of the elastic-restoring force of spring 42
With moulding paper 41 springs back to original position by spring 42, and the first end of blade 1 is accommodated in again in moulding paper 41.
Preferably, the cutter can also include capping.That is, in order to easy to assembly, preferably set on the shell 2 of the cutter
Second opening opposite with first opening is set, blade 1, spring are set in the accommodating chamber in shell 2 to facilitate
42 equal components.The capping may be disposed at the second opening, for closing the second opening, meanwhile, snaps seat 3 can be fixedly connected
In in capping, when capping the second opening of closing, snaps seat 3 is fixed on capping in shell 2.
In addition, generally use winding template carries out coiling to motor, the winding template includes separating two adjacent groups winding
The problem of baffle of coil, the baffle can prevent in winding process, and mutually winding occurs for the enameled wire in former and later two molds.
When the cutter includes two limit protrusions 21, the distance between two described limit protrusions 21 are equal or slightly larger than institute
State the thickness of baffle so that two limit protrusions 21 only can with baffle to just in the case of, be mutually clamped by the square with baffle,
To safely cutting be located at baffle on gummed paper, when limit protrusion 21 not with baffle to timing, two limit protrusions 21 can not
It is engaged by clamping with baffle, limit protrusion 21 can be connected in winding template, not simply failed on cutting baffle so as to cause blade 1
Gummed paper can not also touch winding coil, the problem of being broken or damaged by cutter so as to avoid the enameled wire of winding coil.
To sum up, it will be readily appreciated by those skilled in the art that under the premise of not conflicting, above-mentioned each advantageous manner can be certainly
By combining, being superimposed.
The above, only better embodiment of the invention, not do limitation in any form to the present invention.It is any
People can obtain other various forms of products under the inspiration of the present invention, however, making any change in its shape or structure
Change, it is every that there is technical solution identical or similar to the present application, it is within the scope of the present invention.
