Pen plughole is provided with chamber, the first described bearing, described cavity is arranged on the second described bearing, and cutter hub is arranged on institute
On the first bearing for stating and the second described bearing.
Described base, the first described bearing and the second described bearing is integrally formed.
Be integrally formed the boss for being provided with annular on the lateral wall of described push rod, the rear end of described spring with it is described
The front end face connection of boss.
Compared with prior art, the utility model has the advantage of by being provided with movable braking mechanism on knife rest,
Braking mechanism includes pin, push rod and spring, and the rear portion of knife rest main body is provided with cavity, and the front end of pin is cut in chamber positioned at volume,
The rear end of pin is located in cavity, and the front end of push rod is located in cavity and is fixedly connected with the rear end of pin, and spring is located at cavity
In, spring is set on pin and push rod, and one end of spring and the antetheca of cavity are connected, and the rear end of spring is connected with push rod,
During roll cutting pencil, after pencil size rolls are cut in place, pencil is contacted with pin to be blocked by pin and can not be cut again by volume, when encountering lead
The disconnected core of pen and when being stuck in the situation on knife rest, push rod is promoted forward, now spring is compressed, pin moves forward and pushes away disconnected core
Make the test and cut chamber, thus remove disconnected core, after the core that breaks is removed, decontrol push rod, spring reset drives pin and push rod to reset, user
Just it is and safe；
Include base when knife rest main body, be arranged on the first bearing of pan frontward end, be arranged on the second bearing of base rear end,
Formation volume, which is cut, between base, the first bearing and the second bearing is provided with pen plughole on chamber, the first bearing, cavity is arranged on second
It is simple in construction when cutter hub is arranged on the first bearing and the second bearing on seat, it is easy for installation；
, can be using existing ripe extrusion process come once when base, the first bearing and the second bearing are integrally formed
Shaping, it is simple and convenient；
Annular boss is provided with when being integrally formed on the lateral wall of push rod, the rear end of spring and the front end face of boss are connected
When, it is easy to the installation of spring.
