Description

A kind of pencil-saving protective device
Technical field
The utility model relates to a kind of pencil-saving protective device, belongs to Students ' Learning articles for use technical field of structures.
Background technology
Pencil is the requisite schooling apparatus of the daily study of student, and pencil mainly exists following problem in use and carrying process: 1, the cross section of pencil is most is six face, if writing time is long, can cause pointing swelling and pain; 2, pencil uses length and causes cannot grasp time compared with short-range missile, conventionally can be dropped waste resource; 3, carry words improperly and can cause pencil stub fracture, impact is used.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, easy to use comfortable, improves pencil utilization rate, can make the not pencil-saving protective device of easy fracture of pencil stub.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of pencil-saving protective device, its special character is to comprise both ends open and is the pen cap 1 of hollow cylindrical and the tight loop 7 being used in conjunction with the pen cap 1, one end of the pen cap 1 is connected with cap bag 11, cap bag 11 bottoms are provided with spring 2, the other end of spring 2 is provided with the stopping means for preventing that spring 2 and pencil 10 are separated, the hollow cylindrical fixed cover 5 that stopping means comprises horizontal plane 4 and is made up of silica gel material, the excircle of the pen cap 1 other end is provided with external screw thread and is interval with vertical bar shape opening 6, tight loop 7 is hollow tubular structures, the bore of tight loop 7 one end and the external diameter of the pen cap 1 match, the bore of tight loop 7 other ends and the external diameter of pencil 10 match, the inwall of tight loop 7 is provided with the internal thread being used in conjunction with the external screw thread of the pen cap 1, on the outer wall of tight loop 7, be arranged with silica gel sheath 8, silica gel sheath 8 outer cover are provided with the cap for brush 9.
Beneficial effect: compared with prior art, the utility model reasonable in design, when use, take off cap bag, pencil one end is placed in fixed cover, then cap bag is rotatably connected on the pen cap, tight loop is rotatably connected on the pen cap, because the external diameter of tight loop one end bore and the pen cap matches, the bore of the other end and the external diameter of pencil match, therefore can be by pencil partial fixing in the pen cap by tight loop, the outside silica gel sheath of installing of tight loop plays the effect of protection student finger, be fixed in fixed cover owing to being provided with one end of telescopic spring and pencil in cap bag, length after spring elongates can replace the length of pencil, therefore, even if shorter also can continuation used pencil.In sum, the utility model reasonable in design, easy to use comfortable, improve pencil utilization rate, can make not easy fracture of pencil stub.
Accompanying drawing explanation
Fig. 1: the structural representation of a kind of pencil-saving protective device of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
A kind of pencil-saving protective device of the present embodiment, comprise both ends open and be the pen cap 1 of hollow cylindrical and the tight loop 7 being used in conjunction with the pen cap 1, one end of the pen cap 1 is connected with cap bag 11, cap bag 11 bottoms are provided with spring 2, the other end of spring 2 is provided with the stopping means for preventing that spring 2 and pencil 10 are separated, the hollow cylindrical fixed cover 5 that stopping means comprises horizontal plane 4 and is made up of silica gel material, the excircle of the pen cap 1 other end is provided with external screw thread and is interval with vertical bar shape opening 6, tight loop 7 is hollow tubular structures, the bore of tight loop 7 one end and the external diameter of the pen cap 1 match, the bore of tight loop 7 other ends and the external diameter of pencil 10 match, the inwall of tight loop 7 is provided with the internal thread being used in conjunction with the external screw thread of the pen cap 1, on the outer wall of tight loop 7, be arranged with silica gel sheath 8, silica gel sheath 8 outer cover are provided with the cap for brush 9.
Using method: when use, take off cap bag 11, pencil 10 one end are placed in fixed cover 5, then cap bag 11 is rotatably connected on the pen cap 1, tight loop 7 is rotatably connected on the pen cap 1, because the external diameter of tight loop 7 one end bores and the pen cap 1 matches, the external diameter of the bore of the other end and pencil 10 matches, therefore can be by pencil 10 partial fixings in the pen cap 1 by tight loop 7, the outside silica gel sheath 8 of installing of tight loop 7 plays the effect of protection student finger, be fixed in fixed cover 5 owing to being provided with one end of telescopic spring 2 and pencil 10 in cap bag 11, length after spring 2 elongates can replace the length of pencil 10, therefore, even if shorter also can continuation used pencil 10.
