Description

The structure-improved of push-button type mechanical pencil

The utility model provides the structure-improved of a kind of tool, is meant a kind of structure-improved of push-button type mechanical pencil especially.

By along with the progress of science and technology and the variation of mankind's activity, make the development of a tool also be tending towards variation.

And in many tools, the push type ballpoint pen is a long lasting product, probe into its reason, be that the nib that is the push type ballpoint pen has the function of taking in voluntarily, and need not to mate separately cap, so during the loss of the cap of no known ballpoint pen, can't clamping carry or black liquid is infected with disappearances such as clothing.

In addition, the pencil of being habitually practised with present sound is an example, and on the whole it be with traditional Wood pencil, extensible pencil and start writing in the majority certainly.

As shown in Figure 1 commonly use the push type ballpoint pen, it is the vertical prominent some key ribs 101 that separate with a determining deviation of establishing of the shaft of a writing brush 10 top inner wall on mainly, its be by a left rib tenon 102 and right rib tenon 103 and therebetween slightly the middle rib tenon 104 of depression constitute the setting of each tool rib oblique 105 of the bottom of each rib tenon; And 101 in each key rib is opened a keyway 106, in order to the equidistantly prominent some keys established prominent 202 in a hollow cylindrical retainingf key 201 bottoms be embedded at respectively each keyway 106 with in help in the tenon 104, make it only can upper and lower displacement.These retainingf key 201 bottom tools are the upper gnawing tooth 203 that height rises and falls, so that the key lever 205 of a rotation key 204 inserts in the retainingf key 201, its lower gnawing tooth 206 of establishing of dashing forward is to mesh each other with upper gnawing tooth 203, and it is some 207 that lower gnawing tooth 206 outsides are then set up the key rib separately corresponding to keyway 106 places, so that selectivity embeds in the keyway 106.In addition, rotation key 204 bottom tools one keyhole 208, its can with the chimeric binding in pen core 30 tops, and a pair of lug of establishing of dashing forward on it is after offseting with coil tension spring 40 sockets, so that can press spring 40, then pen core 30 and spring 40 are together inserted in the following shaft of a writing brush 50 of a tool pore 501, with being about to start writing pipe 50 and the last shaft of a writing brush 10 bindings, and the retainingf key 201 and the pressure cap 60 that stretch out outside the shaft of a writing brush 10 are chimeric, promptly form a push type ballpoint pen.
