Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

Embodiment 1

As shown in Figure 1, a kind of rotation two-headed pen, including the coaxially arranged handwriting 1 of connection frame and two, two handwritings 1 Middle part is rotatably coupled to the both ends of connection frame respectively, be equipped between connection frame and each handwriting 1 for control handwriting 1 with The clamp device of the relative rotation of connection frame.

Connection frame include the connecting rods 2 of connecting plate 3 and two parallel arrangements, connecting plate 3 and two connecting rods, 2 one at Type.The middle part of two connecting rods 2 is connect with 3 top and bottom ends of connecting plate respectively, and connecting plate will be separated into two between two connecting rods A independent installation space, two handwritings 1 are separately mounted in two installation spaces of connecting plate two sides；In each handwriting 1 Portion is opened up there are two coaxially arranged mounting hole, and the both ends of each connecting rod 2 are equipped with to be matched and section is with mounting hole Circular mounting head 4, mounting head 4 are connected with corresponding connecting rod 2, and mounting head 4 protrudes into corresponding pen close to one end of handwriting 1 In mounting hole on body 1, each handwriting 1 can be along the center axis thereof of corresponding mounting head 4.The left and right ends of connecting plate 3 V-shaped groove 5 is offered, the pen tip of two handwritings 1 is each positioned in a V-shaped groove 5.

Preferably, mounting head 4 is located at one section outside the mounting hole alar part with arc, and the maximum at 4 alar part of mounting head is straight Diameter is greater than the diameter of mounting hole.

The groove 6 being arranged symmetrically is offered in the handwriting 1 of two sides of mounting hole in each handwriting 1 respectively, clamp device is The elastic raised line 7 cooperated with groove 6, elastic raised line 7 are fixed on the inside of any connecting rod 2.There are four being opened up in each handwriting 1 Groove 6, four grooves 6 are evenly distributed on 1 two sides of handwriting and are arranged symmetrically along 1 central axis of handwriting, corresponding in each connecting rod 2 Be arranged with two elastic raised lines 7, each elasticity raised line 7 respectively cooperates with a close groove 6.

Handwriting 1 can be commonly used for the class marked for pencil, gel ink pen, pen etc..

Wherein preferred, two handwritings 1 can select gel ink pen and Pencil with 2B hardness respectively, special to cope with student and other needs The group of examination is arranged, and avoids forgetting or losing one in gel ink pen and Pencil with 2B hardness and examination is caused not have the case where pen when participating in the cintest. In addition, making the group of different labeled on same document for teacher or other needs, color difference is can be used in two handwritings 1 Pen, be convenient for teacher comment operation, it is easy to use.

Connecting rod 2 need to have certain elasticity, and when installation breaks two connecting rods 2 into two with one's hands slightly, and mounting head 4 is aligned and protrudes into peace Hole is filled, connecting rod 2 is unclamped, connecting rod 2 acts on reset condition next time in elastic returning, mounting head 4 is maintained in mounting hole.It is complete It turns at V-shaped groove 5 at the installation of handwriting 1 and connection frame, and by nib, exerts oneself slightly, enter elastic raised line 7 in groove 6 simultaneously Cooperate with groove 6.

In use, the handwriting 1 is rotated as shown in Fig. 2, the groove 6 in handwriting 1 to be used is pushed to leave elastic raised line 7, Cooperate two grooves 6 in handwriting 1 far from pen tip with corresponding two elastic raised lines 7 respectively, limits the phase of handwriting 1 and connection frame To rotation, that is, handwriting 1 can be used directly and write.When replacing with pen, it is directly rotatablely connected frame, repeats preceding step, it will Pen tip extraction, can hold and be write.It is time saving and energy saving the frequent replacement pen the case where, direct rotation connection frame.

Embodiment 2

Such as Fig. 2,3, the present embodiment the difference from embodiment 1 is that, the length direction in each handwriting 1 along handwriting 1 opens up There are two through slot, two through slots are arranged symmetrically along 1 central axis of handwriting, and two sections positioned at 3 two sides of connecting plate of connecting rod 2 respectively block Enter the through slot in a handwriting 1 in one section of connecting plate 3.

In use, through slot and connecting rod 2 in handwriting 1 to be used is pushed to be detached from, the handwriting 1 is rotated, is made in handwriting 1 Two through slots one section far from pen tip respectively be correspondingly connected with bar 2 and cooperate, limit the relative rotation of handwriting 1 and connection frame Directly write using handwriting 1.When replacing with pen, directly rotation connection frame, repetition preceding step are extracted pen tip out, i.e., It can hold and be write.It is time saving and energy saving the frequent replacement pen the case where, direct rotation connection frame.

Embodiment 3

The present embodiment the difference from embodiment 1 is that, fastening structure is locking mechanism, be fixed with lock body in each handwriting 1, The button with lock body cooperation is hinged in connecting rod 2.By locking for lock body and button, limitation handwriting 1 and connection frame It relatively rotates.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
