Abstract

The utility model provides a splicing sleeved rod of a pencil head. The splicing sleeved rod can be used for connecting the pencil head which is difficult to hold in the conventional use so that the prior waste pencil head can be used continuously, the utilization rate of the pencil is greatly improved, and the waste is reduced. The technical proposal has the key point that the splicing sleeved rod consists of a long rod body, equant claws are processed at the lower end of the rod body and are put aside outwards to be processed into the connector with a shape of a horn, and screw threads are processed on the outer surface of each claw, and the screw threas are screwed with a tubular loop bar.

Description

Pencil head continuous connecting sleeve lever

Technical field

The utility model belongs to the stationery field, specifically is meant the appurtenance of pencil.

Background technology

Pencil is the requisite a kind of articles for use of study office, domestic annual consumption more than billions of, quantity is very big, the length of whole pencil is between 17cm-18cm, that is to say that with holding the length of writing about about 6cm whole pencil at least 1/3 is not utilized and discards and use finally remaining be difficult to again generally speaking, add the pencil-lead point of losing accidentally, what in fact be utilized is no more than 60%, and waste is surprising.

Summary of the invention

The purpose of this utility model designs a kind of pencil head continuous connecting sleeve lever exactly, and it can partly eliminate the waste on pencil utilizes.

Technical scheme is as follows: selecting one section thin tube-like thing that has better elasticity and intensity internal diameter to be same as or to be slightly smaller than the pencil external diameter is the body of rod, on the outer tube wall of one end, be processed with one section screw thread, on the perisporium of the section of a pipe of this machining screw, vertically be divided into two parts equably or three parts become claw; This is begun from the end outwards to bypass by claw of being separated be processed as bell mouth shape and become interface, being with a bit of thick slightly tube in this interface upper end is the bar cover, bar cover inwall be processed with interface on the internal thread that is meshed of external screw thread.

The design's beneficial effect is to use with the continuation of getting up with the remaining pencil stub continued access that cannot use again, has improved the utilization rate of pencil greatly, has reduced waste.

Description of drawings:

A, b are respectively view, the bar cover view of the design's the body of rod among Fig. 1.

Fig. 2 is concrete use aspect graph.

Among each figure, 1 is the body of rod, and 2 is cut-off rule, and 3 is claw, and 4 is interface, and 5 is the bar cover, and 6 is pencil stub.

Specific embodiment:

The pipe that is same as or is slightly smaller than the pencil external diameter with one section internal diameter becomes the body of rod 1, be preferably steel, elastic strength is good, on the outer wall of its lower end, process screw thread, and with the vertical five equilibrium of the perisporium of this section, preferably divide three parts to become claw 3,2 is cut-off rule, and claw is outwards bypassed the interface 4 that is processed into bell mouth shape, as among Fig. 11,2,3,4, intercept a bit of than the thick slightly pipe of the body of rod as bar cover 5, be processed with on its inwall with claw on the silk of external screw thread engagement, for better being connected, skim glue lining can pasted on the inwall of claw 3 with pencil stub.During use, the upper end that hand has been difficult to the pencil stub 6 held is again stretched in the interface 4, from the upper end of the body of rod 1 cover upper boom cover 5 and and claw 3 on silk mesh, along with screwing of bar cover, the claw 3 outside the interface 4 and the joint of pencil be close and firm gradually, as shown in Figure 2, the pencil stub that originally went out of use can continue again to have used normally, test factually, the pencil stub that uses this apparatus to be reused finally can be short to only has an appointment less than 2cm, promptly can with the utilization rate of pencil by before 60% bring up to 90%, significantly reduced waste.

Claims

1, a kind of pencil head continuous connecting sleeve lever is made up of the microscler body of rod, it is characterized in that the lower end at the body of rod is processed with the claw of five equilibrium, and claw is outwards bypassed the interface that is processed into bell mouth shape, and the outer surface of claw is processed with screw thread, is rotary with the bar cover of tubulose on this screw thread.

2, according to the described a kind of pencil head continuous connecting sleeve lever of claim 1, it is characterized in that claw is three parts of five equilibrium, the claw inner surface is stained with soft glue-line.
