Detailed Description
The following description of the embodiments of the present invention will be made in detail and with reference to the accompanying drawings, wherein it is apparent that the embodiments described are only some, but not all embodiments of the present invention. All other embodiments, which can be made by a person of ordinary skill in the art without the need for inventive faculty, are within the scope of the invention, based on the embodiments described in the present invention.
Example 1:
As shown in fig. 1 to 9, the weight loss induction anti-drop pen comprises a pen holder, wherein a pen core seat 5 is slidably arranged in the pen holder, a jack 18 is arranged on the pen core seat 5, a pen core 4 is inserted in the jack 18, 2 elastic sheets 19 are symmetrically arranged on the jack 18, the elastic sheets 19 incline towards the inner side of the pen core seat 5, the pen core seat 5 clamps the pen core 4 through the elastic sheets 19, the elastic sheets 19 are arranged to ensure that the resistance is small when the pen core 4 is inserted, the resistance is large when the pen core 4 is pulled out, the pen core 4 is not easy to slide out when the pen core is used, a deflector rod 17 is further arranged on the side edge of the pen core seat 5, a magnetic attraction structure is further arranged in the pen holder, the magnetic attraction structure adsorbs the pen core seat 5, the magnetic attraction structure comprises a magnet C8 arranged on the pen core seat 5, a magnet A9 and a magnet B10 arranged on the pen core seat 5, the magnet A9 and the magnet B10 are arranged along the axial direction of the pen holder and have the same magnetic pole direction, the refill seat 5 moves upwards to enable the magnet C8 and the magnet A9 to be mutually adsorbed, the refill seat 5 moves downwards to enable the magnet C8 and the magnet B10 to be mutually adsorbed, a retraction structure is further arranged between the refill seat 5 and the pen holder, when the refill 4 touches the ground, the refill seat 5 retracts the refill 4 into the pen holder through the retraction structure, the retraction structure comprises a magnet D7 and a cam 6, the cam 6 is rotationally connected into the pen holder through a rotating shaft 14, a coupling 15 is further arranged on the cam 6, a coupling hole 16 is arranged on the refill seat 5, the coupling 15 is connected with the coupling hole 16 in a matched manner, a magnetic pole at the lower side of the magnet D7 is the same as a magnetic pole of the magnet A9 towards the inner side of the pen holder, the magnet D7 is slidingly connected into the pen holder and is mutually matched with the cam 6, the magnet D7 slides downwards to clamp the cam 6 so as to limit rotation of the cam 6, after the magnet D7 slides upwards, the cam 6 rotates to drive the refill seat 5 to move upwards, the pen holder comprises a rear pen holder 3, a chute is arranged on the rear pen holder 3 for the magnet D7 to slide, a mounting groove 12 is further arranged on the rear pen holder 3 for mounting the cam 6, the pen holder further comprises a middle pen holder 2, a push rod 13 is arranged on the upper side of the middle pen holder 2, an arc notch is arranged on the push rod 13 and is matched with the cam 6, a moving groove is arranged on the middle pen holder 2 for the deflector rod 17 to slide up and down, a buckle is arranged on the rear pen holder 3 and is connected with the middle pen holder 2, a pen clip 11 is further arranged on the middle pen holder 2, a magnetic structure is arranged on the upper side of the pen clip 11, the front pen holder 1 is connected with the middle pen holder 2 through threads.
Based on the principle of attraction between opposite poles of the magnet, when the pen core seat 5 is pushed to retract the pen core 4 into the pen holder, the magnet C8 is close to and attached to the magnet A9 so as to keep the pen core 4 in a retracted state, and when the pen core seat 5 is pushed to extend the pen core 4 out of the pen holder, the magnet C8 is close to and attached to the magnet B10 so as to keep the pen core 4 in an extended state.
Based on the principle that magnets with the same poles repel each other, the magnets D7 and the magnets A9 have repulsive force. When the anti-falling pen is in a vertical static state, the magnet D7 receives the gravity force, the gravity force is larger than the repulsive force of the magnet A9, the magnet D7 falls down and clamps the cam 6 so that the cam cannot rotate, the pen core 4 is locked in an extending state, writing is convenient, when the anti-falling pen falls into a weightless state, the magnet D7 receives the repulsive force of the magnet A9 at the same time, and finally slides into the upper side of a sliding groove of the rear pen holder 3, so that the rotation of the cam 6 is not limited any more, and at the moment, if the pen core 4 collides with the ground or other objects, the pen core 4 can be retracted into the pen holder rapidly, and therefore a pen point on the pen core 4 is protected from being damaged.
