Furthermore, a tightening belt fixedly connected with the pen holder is arranged on the pen holder.

Due to the adoption of the technical scheme, the invention has the following advantages:

1. according to the invention, the tightening belt is fixed on the incomplete arm or palm, and the magnet on the pen clip and the pen holder connected to the tightening belt are mutually adsorbed, so that the color pen inserted in the pen cap can be easily pulled out, and the functions of writing and drawing of the incomplete arm patient and quick switching of the painting brush are realized.

2. The pen cutting device is provided with the pen rack turntable, the steel balls are arranged in the pen rack turntable, rotary damping is generated by the sliding of the steel balls in the ball grooves, force feedback is realized through the ball recesses on the base, the pen cutting device is more stable, and the painting brushes can be switched conveniently and quickly when the pen cutting device is used.

3. The pen rack turntable is internally provided with the spring and the bolt, and the resistance of the turntable during rotation can be adjusted by adjusting the tightness of the bolt, so that the usable group range is expanded.

4. The invention adopts the module design, can randomly change the number of the painting brushes, realizes the diversification of the painting range and saves more space for the vertical pen placing.
