Piston water-suction type white board pen

Abstract

The invention provides a piston water suction typed white board pen. A piston which is blocked and arranged in the hollow core penholder of the white board pen is clamped on vertical slideways which are arranged at two sides of the internal wall; the piston is screwed in the internal thread of a spiral rod by a screw head which is connected with a connecting rod; the spiral rod is connected with the hollow core penholder by a spiral clamp; and the hollow core penholder is provided with a pen core and sponge and a plurality of fine holes. By rotating the spiral rod, the white board pen leads the piston to be telescopic freely on the slideway, thus sucking the ink in and providing convenience for the usage of the white board pen.

Description

Technical field [0001] The invention relates to a stationery article, in particular to a piston-absorbing whiteboard marker. Background technique [0002] The whiteboard markers currently in use are either disposable or inhaled through a built-in sponge, but the water-absorbing type is generally self-absorbing by the sponge, which has the problem of limited water absorption and unsustainable use. Contents of the invention [0003] The invention provides a piston water-absorbing whiteboard marker, which can absorb enough ink at one time through the built-in piston. [0004] The present invention includes a hollow pen holder, a rotating rod, a built-in piston, a connecting rod, a screw head and its sponge, a pen core, a fine hole, and a slide rail. The adopted technical scheme is: the piston in the hollow pen holder is stuck on On the vertical slide rails on both sides of the inner wall, the screw head connected by the piston through the connecting rod is screwed into the i...
