Specific implementation mode

The utility model is further described with specific embodiment below in conjunction with the accompanying drawings,

As shown in Figs. 1-5,

The stage casing of a kind of finger tip rotary pen, including pen body 1, the pen body 1 offers a through-hole 2, is equipped in through-hole 2 One bearing 6 is equipped with a shaft 5 in bearing 6, and shaft 5 is provided at both ends with hand-held part 1 and hand-held part 28, realizes a kind of use In playing, the function of finger tip gyro has been transplanted on pen by the pen that can be rotated in finger tip.

Preferably, wherein one end of the through-hole 2 extends inwardly to form bearing block 4, and the bottom of bearing block 4 is provided with axis Hole 22 is equipped with the bearing 6 in bearing block, and shaft 5 passes through axis hole 22 and is placed on 6 inner ring of bearing, the utility model Bearing 6 is not affixed to center, in order to enable pen core normal through but capable of also playing the role of fixed axostyle 5.

Preferably, the side of the bearing block 4 is provided with pen core channel 3, and the left and right sides in pen core channel 3 is respectively communicated with pen The forward lumen 83 of body and rear portion inner cavity 84, rope, enable pen core normal through.

Preferably, 1 integrated injection molding of the bearing block 4 and pen body, increases the stability between bearing block and bearing, And save material.

Preferably, the pen core channel 3 is arranged in the side of shaft 5 and bearing block 4, and pen core 31 passes through pen core channel 3 simultaneously It is arranged in a curve way in inner cavity 13, this structure can make pen core skip over shaft 5 and can play the role of certain fixed axostyle.

Preferably, the tail portion of the pen body 1 is provided with a pen cap 9, and the written place of pen body 1 is provided with a pen cover 10, described The top of the pen cap 9 is provided with gravity block 1, and the top of pen cover 10 is provided with gravity block 2 12, the gravity block 1, gravity On the same axis with pen body 1, gravity block increases the weight at both ends to block 2 12, enhances centrifugal force, and gravity when rotated Block is installed on the same axis, and balance is enhanced.

Preferably, the both ends of the pen cover 10 and the pen cap 9 open up that there are two mounting groove, the gravity block 1 and gravity blocks 2 12 are fixedly mounted in slot, and pen cover 10 and the casting technique of the pen cap 9 is made to become simple.

Preferably, the weight of the gravity block 2 12 is slightly larger than the weight of gravity block 1, and nib is lighter than pen body end, therefore The weight of gravity block 2 12 needs, less times greater than gravity block one, to ensure that the gravity received at both ends is equal.

Preferably, the gravity block 1 and gravity block 2 12 are ball-shape gravity block, and spherical relatively good molding, gravity compares Good control, and compare and have for the gravity block of corner angle not rapid wear, it reduces later stage gravity block weight and leads to the problem of deviation.
