Problems solved by technology
The above two patents realize the switching between two pens by using a wheel with a cam, which has the characteristics of forward and reverse rotation and relatively flexible rotation, but there are still some shortcomings: the inner sleeve with a straight guide groove The above-mentioned British patent has the disadvantages of troublesome installation of the inner sleeve, complicated assembly process, and the possible movement of the inner sleeve, which affects the use; while the above-mentioned US patent has no guiding device, and the pen core is generally a plastic part, which is prone to deformation. As a result, it may cause problems with the cooperation of the runner and the slider and affect its actual use.

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] like Figure 1 ~ Figure 1 As shown in 0, it is a rotating pen with three refills, including a pen holder 10, a pen holder 4, a refill 9, a coupling 3 and a runner 5;
[0023] The lower part of the runner 5 is a cam structure 5B, and there is a concave part 5A at its end, see Fig. 8, its tail part is set in the connector 3, and cooperates with the groove 3B on the inner wall of the connector through the convex rib 5D on the outer wall positioning, so as to limit the relative rotation of the runner 5 and the coupling 3, see figure 1 , Figure 5 and Figure 8;
[0024] The upper half of the connecting piece 3 extends out of the penholder 10, and the lower half is located in the penholder 10, and is embedded in the annular groove 10B at the upper end of the penholder 10 through the annular rib 3A on it, so that the connecting piece 3 can ...

A multi-tip rotary pen is composed of pen holder, at least two pen cores, and pen core selecting mechanism at the tail of pen holder. Said pen core selecting mechanism consists of clamper at tail of pen holder, rotary wheel linked to said clamper, and slide block at tail of pen core and moving along the pen holder under the action of cam in the front of rotary wheel. Its advantages include simplestructure, low cost and flexible switching between pen cores.
Description
technical field [0001] The invention relates to a writing implement, in particular to a pen with a plurality of conveniently convertible writing nibs. Background technique [0002] The multi-tip revolving pen is popular because it has multiple colors or multiple writing materials, the nib can be retracted into the pen, and it is easy to use or carry. The British patent GB2013579A provides a double-tip rotating pen, which uses the combination of the wheel with a cam and the slider of the top-mounted refill to realize the switching of the writing nib. In order to ensure that the slider can drive the refill to move up and down smoothly in the pen holder, It is tightly plugged with an inner sleeve with a guiding straight groove in the pen holder, and the slider is limited to move up and down in the guiding straight groove. Another example is the composite double nib pen provided by U.S. Patent No. 5,642,953, which also adopts the mode that the runner with cam cooperates with th...
