Abstract
The utility model relates to a rotary eraser and belongs to the field of erasers. The rotary eraser comprises a jacking barrel, a jacking bolt and a rotary knob, wherein the jacking barrel, the jacking bolt and the rotary knob are mutually matched. The rotary eraser is characterized in that a cross-shaped channel is formed in the jacking barrel, a cross-shaped eraser body is placed in the cross-shaped channel, the tail end of the cross-shaped eraser body is fixed on the jacking bolt, and a protective cover mutually matched with the rotary knob is arranged on the outer edges of the rotary knob. The cross-shaped channel is formed in an existing lipstick tube, the cross-shaped eraser body is placed in the cross-shaped channel, and thus the fixation is firm; due to the fact that the eraser body can only stretch in the front-and-back direction and can not rotate relative to the jacking barrel, tiny parts can be erased with the four corners of the cross shape, rotation is avoided, the rotary eraser overcomes the defects that a traditional eraser is bare and thus prone to being dirty and damaged, waste of the eraser is avoided, and economy is promoted.
Description
Technical field
The utility model provides a kind of rotation erasing rubber, belongs to the erasing rubber field.
Background technology
Utility model CN200820222818.8 provides a kind of rotary erasing rubber of being made up of ring-type knob and pipe, it is characterized in that: in the existing ring-type knob of lipstick with pipe an erasing rubber is set.During use, need only turn ring-type knob, then erasing rubber screws out.With being equipped with back turn in the other direction ring-type knob, then enter.Simple in structure, easy to use, prevent that erasing rubber fracture is effective.
The deficiency of its existence is that the rubber clamping of column type is not tight, rotates in pipe easily.After using a period of time, during with the tiny position of erasing rubber, rotate the rubber trouble, bad operation.
The utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: a kind of fixation is provided, is convenient to wipe tiny position, the convenient rotation erasing rubber that uses.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotation erasing rubber; comprise the jacking tube, jacking bolt and the knob that cooperatively interact; it is characterized in that: cross passage is set in the jacking tube; cross channel interior is placed cross rubber; the end of cross rubber is fixed on the jacking bolt, and the knob outer arranges the over cap that cooperatively interacts.
In the existing lipstick mouth of pipe cross passage is set, the cross rubber of inner placement, fixation; Rubber is flexible with front and back only, can not rotate with the jacking tube relatively, can avoid rotation with four cross positions that the angle wiping is tiny.
Wherein preferred version is:
Described over cap arranges edge in the projection, and described knob arranges recessed outer, and the edge adapts with recessed outer in the projection.Be convenient to being used of over cap and knob.
Compared with prior art, the beneficial effect that this rotation erasing rubber has is: by cross passage is set in the jacking tube, cross channel interior is placed cross rubber, the end of cross rubber is fixed on the jacking bolt, the knob outer arranges the over cap that cooperatively interacts, to in the existing lipstick mouth of pipe cross passage be set, the cross rubber of inner placement, fixation; Rubber is flexible with front and back only, can not be relatively and the rotation of jacking tube, can avoid rotation with four cross positions that the angle wiping is tiny, and overcome the shortcoming that traditional rubber exposes easy dirty cracky, avoid rubber to waste, advocate saving.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein, 1, knob 2, jacking bolt 3, jacking tube 4, rubber 5, over cap.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment 1:
As shown in Figure 1; jacking tube 3, jacking bolt 2 and knob 1 cooperatively interact; be similar to the lipstick tube minor structure; cross passage is set in the jacking tube 3; cross channel interior is placed cross rubber 4; the end of cross rubber 4 is fixed on the jacking bolt 2, and knob 1 outer arranges the over cap 5 that cooperatively interacts.
Over cap 5 arranges edge in the projection, and knob 1 arranges recessed outer, and the edge adapts with recessed outer in the projection.Be convenient to being used of over cap 5 and knob 1.
Operation principle or use
In the existing lipstick mouth of pipe cross passage is set, the cross rubber of inner placement, fixation; Rubber 4 is flexible with front and back only, can not rotate with jacking tube 3 relatively, can avoid rotation with four cross positions that the angle wiping is tiny.
