Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of novel card-smearing writing appliance that can realize accurately wiping answer.
Novel card-smearing writing appliance of the present utility model, comprise pencil shaft and the pencil-lead being arranged on pencil shaft inside, described in it, novel card-smearing writing appliance also comprises rubber penholder, eraser core, the cap for brush and lock ring, the bottom of described rubber penholder is removably disposed in the top of pencil shaft by screw thread, the described cap for brush is threaded connection the top at rubber penholder, the top of the described cap for brush is with perturbing sheet, described perturbing on sheet is threaded, described lock ring center line offers and the wedge shaped wires hole, screw thread suitable ground perturbed on sheet, described eraser core is arranged on the inside of rubber penholder, and top, eraser core ground is arranged in the cap for brush, described eraser core is the rectangular structure of flat.
Further, novel card-smearing writing appliance of the present utility model, the top of described pencil shaft offers the first groove, is provided with rubber bumper in described first groove, and the bottom surface of described rubber penholder offers the second groove.
Further, novel card-smearing writing appliance of the present utility model, the top of the lateral surface of described pencil shaft is provided with external screw thread, and the medial surface of the bottom of described rubber penholder is provided with internal thread.
Further, novel card-smearing writing appliance of the present utility model, on the lateral surface of described pencil shaft, cover has elastic tape.
Further, novel card-smearing writing appliance of the present utility model, described pencil shaft and rubber penholder are made of plastics respectively.
By such scheme, the utility model at least has the following advantages: novel card-smearing writing appliance of the present utility model is comprised pencil shaft and is removably disposed in the rubber penholder on pencil shaft top by screw thread, the inside of rubber penholder is provided with eraser core, eraser core is the flat rectangular structure be made up of hard rubber, its principle is the same with common pencil card-coating pen, be provided with the cap for brush on a top and perturb sheet, perturb on sheet and be provided with lock ring by screw thread, after operating personnel upwards rotate lock ring, rubber pen core is just fixed in the cap for brush.Find that when examinee takes an examination answer mistake needs only novel card-smearing writing appliance to be turned over and use eraser core by its wiped clean during amendment, because the contact area of rubber pen core and paper is less, therefore, it is possible to more accurately will answer wipe and other ground answers can not be had influence on mistakenly.In sum, novel card-smearing writing appliance of the present utility model can realize accurately wiping answer.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the novel card-smearing writing appliance of the utility model;
Fig. 2 is the partial enlarged drawing in A portion in Fig. 1.
In figure, 1: pencil shaft; 2: pencil-lead; 3: rubber penholder; 4: eraser core; 5: the cap for brush; 6: lock ring; 7: perturb sheet; 8: the first grooves; 9: rubber bumper; 10: the second grooves; 11: elastic tape.
