Description of the Related Art Conventionally, when a ballpoint pen of this type is extended or contracted, a permanent magnet and a magnetic body provided on a front shaft main body and a rear shaft main body are magnetically attached when contracted. The contracted state is maintained by wearing. [0003] As a result, the magnetic field lines may leak from the surface of the rear shaft body or the front shaft body, so that the magnetic field lines are prevented from leaking or become expensive, and even if the leakage prevention processing is performed, the complete magnetic field lines are prevented. Unable to prevent cache car
The magnetic card such as a card may be damaged. Further, since the permanent magnet needs to have a thickness, the entire length of the permanent magnet at the time of contraction increases by the thickness, and the assembling work is difficult due to the magnetic force of the magnet.
At the time of assembling, there is a drawback that the push rod is easily pulled out and the assembling work is delayed. SUMMARY OF THE INVENTION Accordingly, the present invention provides a magnetic card such as a cash card which holds a front shaft body and a rear shaft body in a contracted state by using a hook without using a magnet. In order to eliminate damage caused by magnetic leakage even when touched, to shorten the overall length at the time of contraction, to make it more portable, and to assemble more easily and to improve the work efficiency. . SUMMARY OF THE INVENTION The present invention comprises a front shaft portion and a rear shaft portion which is slidably fitted to the front shaft portion and is adjustable in expansion and contraction. The front shaft portion has a base. A screwed tip shaft main body, a ball-point pen refill which is removably fitted into a core cylinder provided in the tip shaft body to protrude the core from the base, and a coil spring and a base between the ball-point pen refill and the base. A sliding tip that can freely protrude to a position at which the tip of the ball-point pen refill is concealed via a stopper, a push rod that projects rearward of the tip shaft and allows the sliding tip to be freely pressed against a coil spring; The insertion part that penetrates the air hole for inserting the core tube, the male hook that protrudes from the back of the front shaft body, and the regulating part of the push rod that penetrates by providing an inner space are located and fixed to the rear part of the front shaft body The rear axle is attached to the rear axle body and the rear end of the axle body. A female hook corresponding to the male hook and a clip and a rear axle crown, which are sandwiched between the crowns via a clip holder, and the push rod is slid by pushing the rear axle body into the front axle body. The female hook is freely engageable with the male hook of the front shaft body 3 at the position where the rear shaft body is pushed in, and the joint between the front shaft portion and the rear shaft portion is in contact with the rear portion of the front shaft body. This is a telescopic ballpoint pen, which is composed of a blade spring mounted and attached, and a sheath core fixed to the tip of the rear shaft main body, so that the sheath core and the blade spring can be hooked freely. BRIEF DESCRIPTION OF THE DRAWINGS FIG.

And a sliding tip 8 that can freely protrude to a position where the tip of the ball-point pen refill 6 can be concealed via a ', and a sliding tip 8 that projects rearward of the tip shaft 1 and can be pressed against the coil spring 7. A push rod 9, an insertion portion 11 penetrating through an air hole 10 into which the core tube 5 is inserted, a male hook 12 protruding rearward of the front shaft main body 3, and a regulating portion of the push rod 9 which penetrates by providing an inner space 13. A front shaft crown 15 fixed to the rear portion of the front shaft main body 3 with the position 14 positioned. The rear shaft portion 2 includes a rear shaft main body 16 and a rear shaft main body 16.
At the rear end, a female hook 19, a clip 20, and a rear shaft crown 21 corresponding to the male hook 12 which are sandwiched between U-shaped crowns 17 and 17 'and are provided internally via a clip holder 18 And more. The push rod 9 enables the sliding tip 8 to be freely pressed by the pushing operation of the rear shaft body 16 into the front shaft body 3, and the female hook 19 moves the male hook 12 of the front shaft body 3 at the pushing position of the rear shaft body 16. And can be freely engaged. A joint portion 22 between the front shaft portion 1 and the rear shaft portion 2 is provided with a blade spring 23 which is mounted in contact with the rear portion of the front shaft body 3.
23, and a sheath core 24 fixed to the front end of the rear shaft main body 16. The sheath core 24 is a blade spring 23,
23 and can be hooked freely. The moving distance of the sliding tip 8, the length of the push rod 9, the position of the restricting portion 14, the length of the inner space 13, the length of the ball-point pen refill 6, and the like are determined in relation to each other. The restricting portion 14 of the push rod 9 has a front crown 15
And press-fitted into the through hole 15 ′ provided in the inner space 13. The present invention is embodied as described above.
In order to change from the extended state of FIG. 1 to the contracted state of FIG.
, And pushes the base stopper 7 ′ and the sliding tip 8 forward against the coil spring 7, and refills the ballpoint pen 6.
Male hook 12 and female hook 19
And the whole is in a contracted state as shown in FIG. The rear hook body 16 is pulled rearward to pull the male hook 1
2. By releasing the hook of the female hook 19, the pressing of the push rod 9 against the sliding tip 8 is released, and the sliding tip 8 is pulled inward by the coil spring 7, and at the same time, the core of the ballpoint pen refill 6 is exposed. 1 is in the extended state. As described above, the present invention comprises a front shaft portion and a rear shaft portion which is slidably fitted to the front shaft portion and is adjustable in expansion and contraction. A ball-point pen refill having a tip shaft body, a ball-point pen refill having a core tip protruding from a base by being removably fitted into a core cylinder provided in the head-shaft body, a coil spring and a base stopper between the ball-point refill and the base. A sliding tip that can protrude to a position at which the tip of the ball-point pen refill is concealed through a push rod, a push rod that projects rearward of the tip shaft and allows the sliding tip to be pressed against a coil spring, and the core cylinder. The insertion part penetrating the air hole, the male hook protruding from the rear of the front shaft main body, and the regulating part of the push rod penetrating by providing an inner space are positioned and fixed to the rear part of the front shaft main body. The rear axle is located between the U-shaped crown and the rear end of the axle body. It consists of a female hook corresponding to the male hook installed inside via a clip holder, a clip, and a rear axle crown. The push rod presses the sliding tip by pushing the rear axle body into the front axle body. The female hook can be freely engaged with the male hook of the front shaft body 3 at the pushing position of the rear shaft body, and the joint between the front shaft portion and the rear shaft portion comes into contact with the rear portion of the front shaft body and is attached to a blade spring. And a sheath core fixed to the front end of the rear shaft main body, so that the sheath core and the blade spring can be hooked freely. as a result,
Unlike the conventional case, since no magnet is used, there is no danger of leakage of the magnetic field lines from the surface of the rear shaft main body or the front shaft main body. A magnetic card such as a card can be safely carried around. Since the contracted state is maintained by the male hook and the female hook being engaged with each other, the apparatus can be installed in a relatively thin space. Can be
On the other hand, in the case where the conventional magnet is used, since the magnet itself is thick, the overall length at the time of contraction is relatively long, and the compactness is inferior. Although the magnet is difficult to assemble, as in the present invention, the assembling work of the male hook and the male hook inserted between the crowns can be provided simply and at a lower cost. Further, since the restricting portion of the push rod is located in the inner space of the crown of the axle, there is no fear that the push rod will fall off during assembling work or when the base is removed, so that the working efficiency can be improved.
