Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

As shown in FIGS. 1 to 3:

according to the fast-switching double-color whiteboard marker, fast switching of two different color markers is realized in a fast pressing mode, and convenience in switching of the different color markers is improved; the specific connection comprises a pen container shell 1, two channels are arranged in the pen container shell 1, a first color pen 2 and a second color pen 3 are respectively arranged in the two channels, the first color pen 2 and the second color pen 3 are connected together through a linkage rope 6, the linkage rope 6 is provided with a supporting point in the pen container shell, the supporting point can adopt the arrangement of pulleys, and the friction force of the linkage rope moving on the supporting point is reduced.
