Example (b):
the pressing acceleration gyro pen shown in fig. 1 to 10 is characterized in that: comprises a pen body, a pen core and a return spring.
The pen body is formed by connecting a rotating outer ring with a pen holding body and a pen connecting body through a first bearing and a second bearing. The pen core is arranged in the pen holding body.
The connecting pen body is in a hollow cylinder shape, and is internally provided with a limiting ring table, an internal plate and a pressing piece. The limiting ring platform is arranged on the built-in plate, the bottom of the built-in plate is provided with a ratchet through hole, an anti-falling through hole and two extension columns, a rotating shaft column is further arranged between the two extension columns, and one or two turning wheels are further arranged on the rotating shaft column. The bottom of pressing piece is equipped with anticreep and extends post and ratchet extension post above-mentioned, and the end that the above-mentioned anticreep extended the post still is equipped with the anticreep bulge loop, and above-mentioned anticreep bulge loop external diameter is greater than the internal diameter of anticreep through-hole, and above-mentioned anticreep bulge loop card is difficult for deviating from behind the anticreep through-hole. The ratchet wheel extension column is movably sleeved in the ratchet wheel through hole.
Above-mentioned ratchet extends and still is equipped with ratchet locking knot on the post, the ratchet resets and fills up and magnet, but above-mentioned ratchet locking knot is inhaled the thing by magnetism and is made, but above-mentioned ratchet locking knot and ratchet extend the post and connect the cooperation through the hinge, above-mentioned ratchet resets and fills up and arranges the ratchet and extend on the post, specifically lie in between ratchet extension post and the ratchet locking knot, above-mentioned magnet is arranged in on the ratchet extends the post, above-mentioned ratchet locking knot receives the magnetic attraction effect of magnet, toward the magnet side is drawn together, but receive the separation that the ratchet resets the pad, therefore, ratchet locking knot and ratchet extend and stably keep the N degree angle between the post.
The reset spring is sleeved on the anti-drop extension column and is arranged between the pressing piece and the built-in plate.
The rotating outer ring is also internally provided with a rotating inner table, and the top of the rotating inner table is provided with rotating teeth. The direction-changing wheel is provided with ratchet teeth and direction-changing bevel wheel teeth. The deflecting oblique gear teeth are matched with the rotating teeth.
When the pressing piece is extruded by external force, the reset spring is extruded under the stress, the pressing piece integrally moves downwards, the ratchet wheel extension column moves downwards together, and the ratchet wheel locking buckle is contacted with the ratchet wheel teeth, and the ratchet wheel teeth move downwards along with the pressing piece continuously, are influenced by the ratchet wheel locking buckle and start to rotate. When the ratchet wheel teeth rotate, the inner rotating platform can be driven by the deflecting oblique gear teeth and the rotating oblique gear teeth, and accordingly the rotating of the rotating outer ring which is located on the same axis in the inner rotating platform is achieved through vertical external force.
In order to achieve a better use effect of the ratchet locking buckle, the value of N is influenced by the height of the ratchet resetting pad and the distance between the ratchet resetting pad and the hinge joint point of the ratchet locking buckle and the ratchet extension column.
In order to protect the ratchet locking catch 221 and the ratchet teeth 721 better, the service lives of the ratchet locking catch 221, the return spring 5 and the ratchet teeth 721 are prolonged, noise is reduced, and the usability is improved, so that the spring-back is faster. Above-mentioned ratchet resets and fills up self and has elasticity, then when the ratchet locking is detained also can be backward when ratchet tooth again, because the ratchet resets and fills up and has elasticity, then the ratchet locking is detained can not take place too big frictional force with the ratchet tooth to protect ratchet locking and detain and ratchet tooth better, improve the life of ratchet locking and detain, reset spring and ratchet tooth, and noise abatement and improvement performance make its resilience faster.
In order to thereby further reduce unnecessary friction. Make its rotatory effect better, the diversion wheel still is equipped with swivel bearing with extending between the post, and above-mentioned swivel bearing replaces rotating member and extends the post and contradicts.
In order to protect the pen core and enable the pen to stand on a desktop for rotation, the front end of the pen body is also provided with a pen cover.
In order to facilitate the replacement of the pen core, the pen holding body consists of a main body part and a pen head part.
