Abstract
The present invention relates to a sharp, and more specifically to press the pressure port by forming a shim adjusting device on the upper case of the sharp shim
The sharp shim breaks when writing so that it does not interfere with writing.
It is about the sharp which prevented it.
That is, the sharp shim is sent out and the chuck 60 and the sled to send the sharp shim to the outside while advancing when the pressure inlet 80 is pressurized therein
A tip cap 10 having a stopping jaw 11 serving as a stopper to stop after the bar 42 is moved by a predetermined distance;
The case 20 is fastened to the tip cap 10 and the protrusion 21 is formed at the upper end, and the protrusion 21 formed on the case 20.
Groove 31 is formed so as to correspond to the outer shape is formed in a cylindrical shape, the inner side of the sharp core adjusting device formed in a hexagonal shape (
30) and the hexagonal shape is fastened to the inside of the sharp shim adjusting device 30 and one side thereof corresponds to the inner shape of the sharp shim adjusting device 30.
Is formed, and the other end when the threaded portion 41 is formed so as to be fastened to the threaded portion 12 formed on the inner side of the front end cap 10
At the end, the sleeve 42 which stops when the chuck 60 which sends the sharp shim to the outside and retracts after sending the sharp shim is
The slider 40 is formed, and the core tube 50 is formed to keep the sharp core inside the slider 40.
The chuck 60 for discharging to the negative side and the spring 70 for providing the restoring force to return to the original position after receiving the pressure are fastened.
It is characterized by.

The present invention relates to a sharp, and more specifically to press the pressure port by forming a shim adjusting device on the upper case of the sharp shim
The sharp shim breaks when writing so that it does not interfere with writing.
It is about the sharp which prevented it.
In general, Sharp puts a long pencil lead into the inner tube and presses the pressure port formed at the top of the outer casing.
As the inner tube supported by a pring is lifted and resilient, a pencil lead is formed in the lower part of the casing which has passed through the clamping portion at the bottom of the inner tube.
It is pushed out slightly through the cap.
Therefore, as the pencil lead is worn out, simply press the pressure port so that the pencil lead is pushed out slightly through the cap at the bottom of the casing.
It is very convenient to use and when the used pencil core is completely worn out, the new pencil core stored in the inner tube
It is to be pushed out little by little through the cap, and the inner tube always has several pencils
It is very convenient.
By the way, the conventional sharp is the length of the sharp core coming out through the tip cap (1) as shown in Figure 4 from the manufacturing stage
Since the short set sharp has to press the pressure port (2) more than twice, the operation has been cumbersome and the long setting
Since the mechanical pencil is too long in length, the problem of breaking the core during writing occurs.
So, in general, when adjusting the length of the shim, press the presser (2) two times or more to let the shim come out, and then press the presser once again.
It has been adjusted by pushing or pulling the sharp shim with a hand other than the sharp grip.
Adjust the length of the seam as described above when you are troublesome and urgent to write
If you look at the contents to be written is a problem that can not be written.
Sharp according to the present invention devised in view of the above problems, by forming a shim adjusting device on the upper case of the sharp shim
The length of the sharp shim that comes out when pressing the pressure port can be adjusted freely.
The purpose is to provide sharps that prevent intestines.
The present invention for achieving the above object is a sharp shim is sent out and the sharp shim while advancing when pressurizing the pressure port therein
Stopper that acts as a stopper to stop the chuck and sleeve to send the product to the outside after moving a certain distance is formed
A front end cap, a case which is fastened to the front end cap, and has a protrusion formed at an upper end thereof, and a protrusion formed at the case.
The groove is formed to correspond to and the outer shape is formed in a cylindrical shape, and the innermost sharp core adjusting device formed in a hexagonal shape,
It is fastened to the inside of the sharp shim adjusting device is formed in a hexagonal shape so that one side corresponds to the inner shape of the sharp shim adjusting device,
On the other end, if the threaded portion is formed to be fastened to the threaded portion formed inside the tip cap, the end of the sharp core
A slider having a sleeve having a sleeve which stops when the feeding chuck retracts after sending the sharp shim, and the slider
A core tube is formed to keep the sharp core inside, and the chuck to send the sharp core to the outside receives pressure and returns to its original position.
Sharp, characterized in that the spring is provided to provide a restoring force to return and the line to which the sharp seam is sent
Sharp core adjuster and slider are integrally formed inside the case that is fastened to one side of the short cap,
Rotating the case allows the slider to move forward and backward along the threaded portion of the inside of the case so that the length of the sharp seam can be adjusted.
