Abstract

Disclosed is a pencil tube with a sharpening function, wherein a fixing pin(2) is arranged on a pen tube(1); the pencil can be clamped or loosened by the sliding of the fixing pin(2); the pen tube(1) and a cone knife frame(3) are connected by a thread; a drum blade(4) is nested in a ring shape on the cone knife frame(3) and is clamped by a blade clip(5);if the blade clip(5) is loosened, the drum blade(4) can be moved up and down so that the depth of sending the knife and the thickness of the sharpened point can be adjusted. The utility model is particularly applicable for the pupils to use with safety, convenience, sanity and function.

Description

A kind of band is cut the pencil tube of a function

Affiliated technical field: the utility model relates to the pencil tube that a kind of band is cut a function, and the penknife design is put at pencil tube, makes it to unite two into one, and is easy to use, is particularly suitable for the pupil and uses.

The background technology situation: present penknife kind is a lot, and it is also good to cut a quality, efficient, but weak point is all arranged: or it is dangerous, or inconvenient, and also have the part student to form the custom of stinging pencil, not only unhygienic but also cause lead poisoning easily.The utility model is for solving these not enough designs.

Summary of the invention: the pencil tube that the utility model provides a kind of band of portable safety to cut a function, penknife is installed on the pencil tube, pencil is inserted in the pencil tube.In the time of need sharpening the point of a pencil, only need unclamp holding pin, screw off the shaft of a writing brush, hold pencil sharpener, rotation pencil gets final product; When not needing to cut, need not take off pencil tube and just can write; When not writing, unclamp holding pin,, can effectively protect not frangibility of nib fastening again in the retracting pencil pipe of nib top.

Formation of the present utility model: the utility model is made up of the shaft of a writing brush, holding pin, taper knife rest, reel blade, blade clamp, hole clipping.Holding pin 2 is installed on the shaft of a writing brush 1, and the shaft of a writing brush 1 is threaded with taper knife rest 3 usefulness; Reel blade 4 ring sets and block with blade clamp 5 on taper knife rest 3;

Compared with prior art, characteristics of the present utility model are with using with cutting easy to carry, safe in utilization, health.Last class hour of pupil needn't also need not be with the penknife tool separately with the pencil of much cutting.

Description of drawings: Fig. 1 is a longitudinal section view of the present utility model, and Fig. 2 is the tapered knife mantel view, and Fig. 3 is a reel blade view, and Fig. 4 is the AA cross section of Fig. 2 and the BB cross section assembled view of Fig. 3.

Among the figure: 1, the shaft of a writing brush, 2, holding pin, 3, the taper knife rest, 4, the reel blade, 5, the blade clamp, 6, hole clipping.

Specific implementation method: as shown in Figure 1, the shaft of a writing brush 1 is the pipe shape, and length is the length of whole pencil, internal diameter is slightly larger than the pencil external diameter, in the lower end screw thread is arranged, at distance screw thread 1-1.5cm place's design and installation holding pin 2, holding pin pushes away for 2 times and can block pencil in the pipe, makes it and can not slide up and down; The interior pencil of pipe can be free to slide when pushing away on the holding pin 2.Also there is screw thread taper knife rest 3 upper ends, to connect the shaft of a writing brush 1; Reel blade 4 highly is slightly less than taper knife rest 3 height, and reel blade 4 can suitably be moved up and down, and cuts when thin when the needs nib, and reel blade 4 moves down, otherwise then moves up, and fastening by blade clamp 5; The design of taper knife rest 3 lower ends has the retaining head.

Design has two blade clamps 5 on the taper knife rest 3 shown in Fig. 2,3,4, and the relevant position design has two rectangle hole clippings 6 on the reel blade 4; Reel blade 4 is that ring set is fixed on taper knife rest 3 and by blade clamp 5.
