TH5771B - Writing equipment with two fill sections - Google Patents

Abstract

Equipment for writing according to this invention When the rear outer casing has been rotated in one direction The protruding part of the cam Which is the same layer as the rear outer casing Will move to press on the surface on either side of the cam. Of the first and second sliders Which will want them to perform the job Where one of the filling sections will extend and the other retract inward. And while the rear outer casing is rotated in the other direction The cam-grapple protrusion, which is the same layer as the aforementioned rear outer casing, pushes against the cam face on the other side of the first and second slider to operate. Where one of the fill sections is retracted and the other protrudes. Therefore, the performance above Therefore stable and stable

Claims (3)

1. A writing device with two filling sections: The rear outer casing is connected to the rear end of the front outer casing. A sleeve that connects modularly with the tail end of the said front outer casing. And there are parts for filling the first and second to be installed there that move axially. The gripping shaft portion is built on the end of the casing and slidly taps onto the rear outer casing. The first and second sliders connect to the ends of the first and second filling sections, respectively. And slide axially into the rear outer casing The first and second surfaces of the first and second sliders are built on the first and second sliders respectively. The surface of each such ball has an angular trough that extends approximately 180 degrees to the arc, and the cam-gripping protrusion is created on the rear outer casing as follows: It is said to make the surface of the aforementioned of the aforementioned first and second sliders firmly bind to that part at a time. And thus, the first and second filling parts protrude alternately when the rear outer casing is rotated. 2. The writing device has two filling sections, which are: The rear outer casing is connected to the rear end of the front outer casing. A casing that is modularly connected to the tail end of the said front outer casing. And there are parts for filling the first and second to be installed there that move axially. A gripping shaft portion is created on the rear end of the casing. And grind move smoothly with the outer casing on the back The first and second sliders connect to the ends of the first and second filling sections, respectively. And slide axially into the rear outer casing The first and second surfaces of the first and second pegs are built on such first and second sliders respectively. The surface of each such ball has an oblong shape that extends approximately 180 ° of the arc, and the camshell protrusion is created on the rear outer casing. To stabilize the front of the cam, the first and second slider edges grind firmly on that part one at a time. And thus, the first and second filler sections munch firmly on that part one at a time. And therefore, such first and second filling parts can be protruding selectively depending on the rotation of the rear outer casing. Also, a tightening spike is created at the rear end of the casing. The spines for such anchoring will be two lobes. Back so that it can protrude flexibly along the diameter and A hole for the shaft insertion is made in the said rear outer casing. To grind the sliding shaft with the shaft for such action 3. The writing device with the two filling sections identified in claim 2 has an important characteristic: the anti-push back block is placed in such a binding spike in order to prevent the draw spike. Is affected by back pressure in the direction along the diameter
