    The utility model pencil has applied for patent certification by the State Intellectual Property Office of the people's Republic of China

    Patent No.: zl2012 2 0558684, 3

    The pencil of the utility model has a protection function. Through the improvement of the rubber, the running track or shape of the thrown pencil is changed to reduce the harm to the user.

    The pen holder is hexagonal, a pen holder is sleeved on the hand holding part of the pen holder, the inner wall of the pen holder is circular and in a transitional fit state with the pen holder, and the ports at both ends of the pen holder are designed with an outward protruding ring platform.

    The rear end of the pen holder is provided with an integral rubber head, that is, an integral wrapping sleeve is arranged at the rear end of the pen holder.

    The rubber head is designed with longitudinal asymmetric inclined plane.

    The rubber head is made of flexible material, and a protruding ring table is arranged outward at the connection with the rear end of the pen holder.

    Compared with the prior art, the utility model has the following beneficial effects:

    Writing end: add pen holder. The pen holder is hexagonal, so that the contact between the pen holder and the pen holder is 6 points, resulting in less friction and transitional fit. During normal writing, the clamping force of the hand makes no sliding between the pen holder and the pen holder. When the pen is thrown out of the hand, the clamping force of the hand disappears. When the whole pen touches an obstacle, there is a sliding between the pen holder and the pen body. At this time, the pen holder acts as an obstacle to prevent the pen holder from further deepening and reduce the risk.

    Rubber head end: the overall leather head design is adopted to maintain the wiping function of ordinary rubber. When the rubber uses normal rubber materials, the shape is designed into an asymmetric inclined plane by using the mechanical principle. When the pencil is thrown out with the leather head end, the torque is generated due to the non coincidence between the center of gravity of the pen and the contact point of the rubber, which makes the pencil change its original movement direction, so as to reduce the risk. When the rubber is made of flexible material, the design length is increased to increase the instability. When it is squeezed axially, compression plays a buffer role, or deformation changes its movement direction, which plays a role in reducing the risk.
