Preferably, the gravity block 4 is slidably connected to the barrel 1 along the longitudinal direction of the barrel 1, and the gravity block 4 moves along the longitudinal direction of the barrel 1.

Preferably, the gravity block 4 is slidably sleeved on the periphery of the pen core 2 along the length direction of the pen core 2, so that the gravity block 4 moves along the length direction of the pen holder 1.

Preferably, a retainer ring 14 arranged between the pressure rod 12 and the gravity block 4 is arranged in the accommodating cavity of the pen holder 1, the pen core 2 penetrates through the retainer ring 14, the retainer ring 14 is in threaded connection with the pen holder 1, the gravity block 4 is connected with the retainer ring 14 through the first tension spring 5, and when the pen holder 1 is used for writing vertically, the gravity block 4 moves towards the pen point direction of the pen core 2 under the action of self gravity to enable the first tension spring 5 to be stretched for energy storage.

Preferably, the pressing rod 12 is sleeved with a second tension spring 15 arranged in the accommodating cavity of the pen holder 1, and two ends of the second tension spring 15 are respectively connected with the screw cap 3 and the pressing rod 12, so that a structure that the pressing rod 12 slides on the screw cap 3 in a direction away from the pen core 2 through the tension of the second tension spring 15 is formed.

Preferably, the pressing rod 12 is sleeved with a pressing spring arranged outside the screw cap 3, and two ends of the pressing spring are respectively connected with the screw cap 3 and the pressing rod 12, so that the pressing rod 12 slides on the screw cap 3 in a direction away from the pen core 2 through the elastic force of the pressing spring.

Preferably, the penholder 1 is provided with a centripetal sliding groove 18 matched with the stopping slider 9, and the stopping slider 9 is slidably arranged in the centripetal sliding groove 18 to form a structure that the stopping slider 9 centripetally slides on the penholder 1.

Preferably, the first connecting rod 6, the second connecting rod 7, the third connecting rod 8, the stopping slider 9 and the torsion spring 10 are respectively provided with at least two parts and are uniformly distributed along the circumference of the axis of the penholder 1; the blocking of the first connecting rods 6 enables the slider 4 to be stressed uniformly in all directions, and the slider 4 is prevented from being deviated due to the position generated after being blocked by the first connecting rods 6, so that the sliding failure of the blocking slider 9 is avoided.

Referring to the attached drawings 1-2, when the pen is used for writing, the press rod 12 is pressed downwards to enable the pen point of the pen core 2 to extend downwards out of the pen holder 1, the pen holder 1 is erected to enable the pen point of the pen core 2 to face downwards, the gravity block 4 overcomes the pulling force of the first tension spring 5 under the action of self gravity to slide downwards and push the first connecting rod 6 to rotate downwards, the second connecting rod 7 is pushed by the first connecting rod 6 to enable the rotating shaft 16 to slide downwards, and then the stopping sliding block 9 is pushed to slide centripetally through the third connecting rod 8; when the stopping slide block 9 slides centripetally, the stopping slide block gradually approaches to the pen core 2 and stops the stopping flange 11 at the current position so that the pen core 2 cannot move upwards.

Normal writing can be carried out by loosening the pressure lever 12 at this moment, in the writing process, the gravity block 4 can slide up and down in different degrees due to the displacement and the up-and-down vibration of the penholder 1, the gravity block 4 can be effectively prevented from being accidentally separated from the first connecting rod 6 in the writing process by setting the axial length of the gravity block 4, and the writing continuity is ensured.

Referring to fig. 3-4, when the present invention accidentally falls, due to the special free falling trajectory of the spring itself, the lower end of the spring remains stationary or slowly falls, and the upper end rapidly moves downward under the action of the pulling force and gravity of the spring itself to cause the center of mass of the spring to fall; therefore, when the pen point falls downwards, the gravity block 4 connected with the lower end of the first tension spring 5 is kept still or slowly falls, the pen holder 1 connected with the upper end of the first tension spring 5 rapidly falls under the action of the tension of the first tension spring 5 and the gravity of related components, the movement enables the gravity block 4 to slide upwards on the pen holder 1, so that the gravity block 4 is separated from the first connecting rod 6, the first connecting rod 6 rotates upwards under the torsion of the torsion spring 10, the second connecting rod 7 is pulled by the first connecting rod 6 to enable the rotating shaft 16 to slide upwards on the pen holder 1, and the stopping slide block 9 is pulled by the third connecting rod 8 to slide centrifugally; the stopping slide block 9 gradually gets away from the pen core 2 and is separated from the stopping flange 11 when centrifugally sliding, the pen core 2 is not stopped and slides upwards relative to the pen holder 1 along with the pressure lever 12 under the action of the tension of the second tension spring 15, and the second tension spring 15 generates free falling body movement with the same property as the first tension spring 5 in the process; the upward sliding of the cartridge 2 with respect to the barrel 1 causes the tip of the cartridge 2 to be retracted inside the barrel 1, so that the tip is not hit when the barrel 1 is landed.

When the pen point is upward and falls, the first tension spring 5 also generates a free falling body in the same way as the principle, except that the gravity block 4 rapidly moves downwards under the action of the self gravity and the tension of the first tension spring 5 to be separated from the first connecting rod 6, so that the stopping of the pen core 2 is released and the pen point is retracted into the inner side of the pen holder 1, and the pen point is effectively protected; under this condition, can guarantee that the nib can not bump with other objects when the bounce, the roll after the pen-holder 1 drops.

When the pen is picked up again, the pen core 2 needs to be reset, the reset operation is consistent with the operation before writing, the pen can be used only by pressing the pressing rod 12 and then erecting the pen holder 1, and the operation is very convenient and fast.

When the pen is not used, the pen point of the pen can be upward to enable the pen core 2 to retract, then the pen core 2 can be stored or carried, when the pressure rod 12 is not pressed down, the pen core 2 cannot be ejected out, the pen point can be protected, and ink stains caused by contact of the pen point with clothes, paper and the like can be avoided.

The pen holder is exquisite in structure and simple to operate, and the movement characteristic of the spring in free falling is utilized, so that the internal components of the pen holder automatically trigger linkage when falling to quickly retract the pen core into the pen holder, and the pen point is protected timely and effectively; the pen core can be popped up by simply pressing the pressing rod, the pen core has the characteristics of simplicity and quickness of the existing writing pen, and also has an automatic protection function which is not possessed by the existing writing pen, so that a user can easily deal with any emergency, and the user does not need to worry about serious loss caused by damage of the pen point in important occasions.
