| Zusammenfassung: | The utility model provides a vacuum film suction pen which comprises a body suitable for being held and provided with a first end and a second end which are opposite, and a suction mechanism connected to the first end and provided with a suction cup structure. The body and the adsorption mechanism are internally provided with through hole channels, the hole channels are communicated to the suction cup structure and the second end, the second end is suitable for being connected with a vacuum pump, the vacuum pump is suitable for forming negative pressure in the suction cup structure to adsorb materials, the body is provided with an airflow opening communicated with the hole channels, and the airflow opening is suitable for being covered and closed by the hand of a user. According to the vacuum film suction pen, negative pressure is formed through the vacuum pump suction cup structure so that a film sample can be sucked, and the negative pressure strength and the suction capacity of the suction cup structure ca |
