| 摘要 |
<p>The present invention is to provide a cleaning pen (2,3), which includes a hollow clamping device (21) having two clamping units (210) able to be engaged with each other for clamping a wiping element (20,30) in a bent state and being inserted into a hollow housing (22,32) such that a bent portion (203) of the wiping element (20,30) juts out of the hollow housing (22,32) and can be used for cleaning an object. When the bent portion (203) is soiled or damaged, a user can conveniently and sequentially take the wiping element (20,30) out from the hollow housing (22,32) and hollow clamping device (21), and then shift the soiled or damaged portion to a position for allowing the wiping element (20,30) to be clamped by the hollow clamping device (21) again and form a new bent portion (203) jutting out of the hollow housing (22,32), so as to effectively prevent the object from being scratched by edge of the wiping element (20,30) and prolong service life thereof.
