Abstract

PURPOSE: A mechanical pencil with button is provided to form lead control device and control the length of the lead which comes out when pressing the presser. CONSTITUTION: The mechanical pencil with button includes: a chuck; a stuck part; a sleeve; and a lead case. The chuck(60) moves forward and discharges the lead to the outside when pressing the presser(80). The stuck part(11) plays a role as a stopper so the sleeve(42) can move for the regular distance and then stop. The sleeve acts stop when the chuck discharges the lead and moves back. The lead case(50) keeps the lead in the inner side of the slider(40).

Description

Sharp pen exit button

Students need to study

Since the sharp pencil has a length of the sharp core coming out through the tip cap (1) from the manufacturing stage as shown in FIG. 1, the short pencil pencil needs to press the pressure port (2) more than two times. Since the pencil is set too long, the length of the pencil is broken because of its length.

So, in general, when adjusting the length of the shim, press the pusher (2) two times or more to come out of the shim, and then push or pull the sharp shim as a hand other than the hand holding the sharp pencil while pressing the pusher and adjust the length of the shim. come. As the length of the seam is to be adjusted as described above, when the writing of the seam is cumbersome and hasty, adjusting the length of the seam as described above causes a problem in that the handwriting becomes insane.

The pencil pencil devised in view of the above-described problems, the sharp core is formed on the upper case of the sharp shim, so that the length of the sharp shim that comes out when pressing the pressure port can be freely adjusted, so the sharp shim is broken during writing. The purpose is to provide a sharp pencil that prevents disturbances.

The present invention for achieving the above object is a sharp shim is sent out and the stop acts as a stopper to stop the chuck and sleeve to send the sharp shim to the outside while moving forward when a certain distance is pressed when pressing the pressure in the inside The jaw 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, a groove is formed to correspond to the protrusion formed on the case, and an outer shape is formed in a cylindrical shape. The device is fastened to the inside of the sharp shim adjusting device and is formed in a hexagonal shape so that one side corresponds to the inner shape of the sharp shim adjusting device, and another one side

When the threaded portion is formed to be fastened to the thread formed on the inner side of the tip cap, the end has a slider formed with a sleeve which stops when the chuck for sending the sharp core to the outside sends out the sharp core and then retreats, and inside the slider. A core tube is formed to store the sharp shim, and the chuck to send the sharp shim to the outside and to return to its original position after being pressurized

Sharp pencil, characterized in that the spring is provided to provide a restoring force, and the sharp core adjusting device and the slider is integrally formed on the inner side of the case which is fastened to one side of the tip cap to which the sharp core is sent out, the case and screwed to rotate the case If you do so, the slider along the thread inside the case can adjust the length of the sharp seam by moving forward and backward.

Can be used conveniently when writing

The case 20 is fastened to the distal end cap 10 and has a protrusion 21 formed at an upper end thereof, and a groove 31 is formed to correspond to the protrusion 21 formed at the case 20. Sharp shim adjusting device 30 formed in a hexagonal shape, and is fastened to the inside of the sharp shim adjusting device 30 is formed in a hexagonal shape so that one side corresponds to the inner shape of the sharp shim adjusting device 30, the other side The threaded portion 41 is formed to be fastened to the threaded portion 12 formed on the inner side of the end cap 10, and the chuck 60 which sends the sharper core to the outside is stopped when the retracted shaft after the sharper core is sent out. Slider 40 is formed with a sleeve 42, the core barrel 50 is formed to keep the sharp core inside the slider 40, the chuck 60 and the sleeve 42 for sending the sharp core to the outside pressure Springs that provide restoring force to return to their original position after receiving Sharp pencil is characterized in that is fastened.

Claims (2)

Claim 1.
When the sharp shim is sent out and the pressurizing port 80 is pressed therein, the jaw that serves as a stopper so that the chuck 60 and the sleeve 42 which sends the sharp shim to the outside and stop after moving by a predetermined distance ( 11 is formed a front end cap 10, the case 20 is fastened to the front end cap 10, the projection 21 is formed on the upper end, and the projection 21 formed in the case 20 Groove 31 is formed so as to correspond to the sharp core adjusting device 30 is formed in a hexagonal shape on the inside, and the inner side of the sharp core adjusting device 30 is fastened to the inside of the sharp core adjusting device 30 and It is formed in a hexagonal shape to correspond to, the other side is formed with a screw portion 41 to be fastened to the threaded portion 12 formed on the inner side of the end cap 10 and the chuck 60 to send the sharp core to the outside end After sending this sharp shim, the sleeve 42 which stops when it retracts is The formed slider 40 and the core barrel 50 is formed to keep the sharp core inside the slider 40, and the chuck 60 and the sleeve 42 for sending the sharp core to the outside are pressurized and then returned to their original positions. Sharp pencil, characterized in that the spring 70 is provided to provide a restoring force to return to.
According to claim 2, Sharp sharp adjustment device 30 and the sling on the inner side of the case 20 is fastened to one side of the front end cap 10 is sent out sharp sharp
When the rider 40 is integrally formed and screwed with the case 20 to rotate the case, the screw part 22 inside the case 20 is rotated.
Along with the slider 40, the sharp pencil, characterized in that to adjust the length of the sharp core by reversing.
