Description

Connect a device

Technical field the utility model relates to a kind of study article, especially a kind of device that connects.

Technical background is well-known, and pencil is one of writing implement of using always of pupil, and they paint or writing words with pencil.But after pencil constantly consumed, it is shorter and shorter that penholder becomes, to such an extent as to the penholder of holding with a firm grip that students in use can't be comfortable.In this case, most of students can throw away remaining pencil stub, cause the energy and economic dual waste, also are unfavorable for cultivating the custom that the student works hard and practises economy.For this reason, we provide a kind of new-type very necessity of a device that connects that prolongs pencil stub length.

The summary of the invention the purpose of this utility model provides a kind of device that connects, and is used to solve the problem that general tool can't prolong pencil stub length.

For achieving the above object, the utility model connects a device, comprises the shaft of a writing brush and connecting rod, and the top end opening place of the shaft of a writing brush is a tapered configuration, and the opening part diameter equals common pencil diameter, at the sticking card of shaft of a writing brush top end opening place inner wall surface one circle rubber blanket is arranged; Shaft of a writing brush end openings place is a helicitic texture, and the connecting rod top is the screw inserted link, and connecting rod is terminal to be connected with shaft of a writing brush open-top screw thread; Connecting rod is less than shaft of a writing brush length.

After adopting said structure, the user can select the less pencil stub of length, and the nib end is slowly inserted from shaft of a writing brush front opening, makes pencil stub be exposed at shaft of a writing brush opening part; The user inserts the connecting rod top from shaft of a writing brush end openings, when the screw inserted link on connecting rod top with after pencil stub contacts, bar is rotatably connected, screw inserted link and pencil stub are threaded togather, at last the connecting rod end thread be connected shaft of a writing brush end openings place just can, this process has effectively prolonged the length of short and small pencil stub.

The utility model has the advantages that: rational in infrastructure, convenient and practical, good looking appearance, cheap, can increase the length of waste and old pencil stub, increase the service life, save material, avoid waste.

Description of drawings Fig. 1 connects the overall structure schematic diagram of a device for the utility model.

The specific embodiment as shown in Figure 1, the utility model connects a device, comprises the shaft of a writing brush 1 and connecting rod 2, and the top end opening place of the shaft of a writing brush 1 is a tapered configuration 3, and the opening part diameter equals common pencil diameter, at the sticking card of the shaft of a writing brush 1 top end opening place inner wall surface one circle rubber blanket 4 is arranged; The shaft of a writing brush 1 end openings place is a helicitic texture, and connecting rod 2 tops are screw inserted link 5, and connecting rod 2 ends are connected with the shaft of a writing brush 1 open-top screw thread; Connecting rod 2 is less than the shaft of a writing brush 1 length.Wherein, the shaft of a writing brush 1 can adopt rigid plastics, steel pipe or wood materials manufacturing to form; The screw inserted link 5 on connecting rod 2 tops adopts ferrous material to make, and is helical form; Rubber blanket 4 glues and is posted on the shaft of a writing brush 1 inwall, directly contacts with pencil stub, increases frictional force, avoids pencil stub to slide.
