Abstract

The utility model discloses a micro-rubbing machine comprising an outer housing and a thrust device comprising an ejector rod, a spring, a key and a grab bucket and arranged in the outer housing; the ejector rod passes through the outer housing, and the lower end of the ejector rod is fixed with the grab bucket; the spring is contacted with a rack device on the ejector rod; the end part of the spring is provided with the key passing through the lateral face of the outer housing; a rubber strip is blocked and jointed below the grab bucket; and the rubber strip can slide up and down under the action of the thrust device and extends out of the opening at the lower end of the outer housing. The rubber strip is arranged to be an automatically extending device controlled by the key; and little rubber strip with corner is pressed out to well control the range of rubbing when small-range rubbing is needed, and peripheral patterns can not be influenced. Therefore, the micro-rubbing machine has simple structure and convenient use, and also has the function of good micro-rubbing; and the micro-rubbing machine is applicable for generalization in groups such as students, drawing staff, and the like.

Description

A kind of little wiping device

Technical field

The utility model relates to a kind of erase tool, relates in particular to a kind of little wiping device.

Background technology

In making engineering by hand, tending to take place some small mistakes needs to alter, and common rubber grasps rubber can obstruct the view owing to oversize when altering, to such an extent as to other parts that need not alter are wiped in the lump, this just bring paper unclean, inconvenience such as need repaint.Existing erasing rubber all is a monoblock setting, can often use erasing rubber can make the corner of erasing rubber become more slick and sly owing to be affectedly bashful and made dirty with hand during use, need cut out corner angle with cutter etc., can be used for wiping micro patterns easily.

The utility model content

At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of little wiping device, can effectively solve the problem that above-mentioned prior art exists.

To achieve these goals, the technical solution adopted in the utility model is: a kind of little wiping device, comprise the thrust unit of forming by push rod, spring, button, grab bucket in shell and the shell, it is fixing that push rod passes described shell and lower end and grab bucket, spring contacts with rack gear arrangement on the push rod, and spring end is provided with the side that button passes described shell, is connected with the rubber bar below grab bucket, and the rubber bar can slide up and down under the effect of thrust unit and pay by the opening of shell lower end.

The beneficial effect that this utility model is brought is, the rubber bar is arranged to automatics by stretching out by key control, when some need wipe the operation of small scope, but, can not have influence on the pattern of periphery, therefore by the scope that the rubber bar better controlled that goes out a small amount of band water caltrop is wiped, this utility model is not only simple in structure, easy to use, and can well play the effect of little wiping, be beneficial to crowds such as vast student, mapping personnel and promote the use.

Description of drawings

Fig. 1 is the generalized section of the utility model embodiment.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1, as a kind of embodiment of the present utility model, in the present embodiment, utilize this little wiping device of principle design of propelling pencil, automatic ball pen, this little wiping device comprises in shell 1 and the shell 1 by push rod 2, spring 3, button 5, grab bucket 4 thrust units of forming.Push rod 2 passes described shell 1 and lower end and grab bucket 4 is fixing, and spring 3 contacts with rack gear arrangement on the push rod 2, and spring 3 ends are provided with the side that button 5 passes described shell 1, grab bucket 4 below be connected with rubber bar 6.By pressing the spring 3 of button 5 compacting inside, spring 3 is movable together with push rod 2 upper racks, and push rod 2 makes grab bucket 4 down move toward pressing down, and rubber bar 6 is paid toward lower slider and by the opening of shell 1 lower end under the effect of grab bucket 4.In use, rubber bar 6 is aimed at the position that need wipe, because the setting that rubber bar 6 is tiny, can not have influence on the lines on the peripheral drawing simultaneously, whole casing 1 is equivalent to the support of rubber bar 6, make that thinner rubber bar 6 also possesses certain working strength, it is convenient, practical to compare direct use rubber bar.

Claims

1. little wiping device, it is characterized in that: comprise the thrust unit of forming by push rod, spring, button, grab bucket in shell and the shell, it is fixing that push rod passes described shell and lower end and grab bucket, spring contacts with rack gear arrangement on the push rod, and spring end is provided with the side that button passes described shell, be connected with the rubber bar below grab bucket, the rubber bar can slide up and down under the effect of thrust unit and pay by the opening of shell lower end.
