Abstract
The utility model relates to an auxiliary device for a pencil, in particular to a pencil lengthening rod device. The device mainly solves the technical problems that the pencil lengthening device fixes pencils in a lengthening rod through a sleeve or a claw hand and pencils shake in the lengthening rod to influence the use due to insufficient fixing strength of an interface in actual use in the prior art. The pencil lengthening rod device comprises a strengthened pencil body (1) which can be sleeved on the pencil, and is characterized in that: a threaded port (2) capable of sleeving with the pencil is formed at the front end of the strengthened pencil body (1); and a thread tapper (3) is movably connected to the rear end of the strengthened pencil.
Description
Technical field
The utility model relates to the servicing unit that a kind of pencil uses, and especially relates to a kind of pencil elongated lever apparatus.
Background technology
The fixedly pencil of fixing between carbon black lead for retractable pencil and pencil shaft, it is the writing implement that a kind of people use always, especially departments such as education, design, drawing that are used for more, its consumption is very big, when pencil is used certain stage, because length is shorter, poorly be affectedly bashful, therefore usually just discarded, but its remaining part in fact can also write, therefore waste is bigger.Chinese patent discloses a kind of pencil elongated penholder (Granted publication number: CN 2792802Y), its end at main pen arm connects the penholder headgear, in the penholder headgear, settle the claw hand who holds pencil stub, the claw hand is connected with center rod, overlaps compressible spring on the center rod, and the center rod other end connects the cap for brush that can insert the erasing rubber head, finger is pressed the cap for brush, thereby the compression spring by center rod, is released the claw hand from the penholder headgear, the claw hand opens automatically, put into the short pencil head, decontrol the finger of pressing the cap for brush, reply at spring under the effect of tension force, the claw hand catches pencil stub, retract in the penholder headgear, short pencil and penholder are become one, the convenient use; Hold the claw hand of pencil stub, inboard coarse shape structure for the band point, after the claw hand stretches out from the penholder headgear, under self tension force effect, open automatically, when the claw hand bounces back, under the effect of pen head cover, shrink and close up, hold on pencil stub, retract to together in the penholder headgear, make pencil stub when writing, not loosening.Chinese patent also discloses a kind of pencil elongated device (Granted publication number: CN 201405609Y), it comprises outer tube and the interior pipe that is sleeved on together, the outer tube bottom is provided with bolt hole, interior pipe top is provided with the bolt hole of same diameter, and interior pipe lower end is provided with frustum so that the installation sleeve of pencil to be installed, and the two connects as one by the screw that passes bolt hole.But these two kinds of pencil elongated devices all are to adopt socket or cleft hand that pencil is fixed in the extension bar, and pencil can rock in extension bar and form pencil because the constant intensity of interface is not enough when reality is used, and influence is used.
The utility model content
The utility model provides a kind of pencil elongated lever apparatus, it mainly is that the pencil elongated device of solution existing in prior technology all is to adopt socket or cleft hand that pencil is fixed in the extension bar, pencil can be because the constant intensity of interface be not enough when reality is used, in extension bar, rock the technical problem of influence use etc. and form pencil.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of pencil elongated lever apparatus of the present utility model comprises a reinforcing body that can be socketed on the pencil, but it is characterized in that a described reinforcing body front end is provided with the screw thread mouth of socket pencil, and the rear end that reinforces a body is connected with thread tapper.The diameter of reinforcing a body is greater than the external diameter of pencil, is convenient to pencil like this and is inserted into a reinforcing body inside.Utilize thread tapper to carry out tapping, make the pen of pencil be distributed with external screw thread on one's body, more threaded pencil is connected in the screw thread mouth of reinforcing a body front end, connect more firm like this a body of pencil.The internal thread of thread tapper and the internal thread of screw thread mouth are complementary, and can fix so that the pencil after the tapping can directly screw in screw thread mouth like this.A reinforcing body and thread tapper can arbitrarily not dismantled when not using like this owing to flexibly connect, and load onto during use to get final product.
As preferably, the rear end of a described reinforcing body is threaded or the clamping thread tapper, and the rear end of thread tapper is connected with gag.By be threaded, mode such as clamping installs thread tapper, the assembling of thread tapper is comparatively simple, and gag is installed at the thread tapper place, can prevent staff in the scratch of thread tapper place, and can prevent that the wood chip in the thread tapper from leaking.
As preferably, be provided with the cavity that to deposit wood chip in the described reinforcing body.Cavity is communicated with thread tapper, and the wood chip that the thread tapper smear metal is got off promptly can enter in the cavity and deposit, and when toppling over wood chip, only need unload thread tapper and get final product.
Therefore, the utility model concentrates on thread tapper and screw thread mouth and reinforces on one's body the pen, makes pencil reinforce on one's body the pen through can directly being threaded in after the tapping, easy to use, and reinforce a body and thread tapper and flexibly connect, can assemble as required, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Parts, position and numbering among the figure: reinforce a body 1, screw thread mouth 2, thread tapper 3, gag 4, cavity 5, pencil 6.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of pencil elongated lever apparatus of this example, as Fig. 1, a reinforcing body 1 that can be socketed on the pencil 6 is arranged, reinforce the external diameter of the diameter of a body greater than pencil 6, reinforce a body inside and be provided with the cavity 5 that can deposit wood chip.But the front end of reinforcing a body is provided with the screw thread mouth 2 of socket pencil, and the rear end that reinforces a body is connected with thread tapper 3 by screw thread, and the rear end of thread tapper is provided with gag 4.Thread tapper is communicated with cavity.
During use, open gag 4, pencil 6 ends are inserted in the thread tapper 3 carry out tapping, form external screw thread up to the pencil outer surface.With the internal thread place that reinforces a body 1 front end screw thread mouth 2 that screws into of pencil, finish fixing then.Hold and reinforce a body, can write.When the wood chip in the cavity fills with, can unload thread tapper, the wood chip in the cavity is toppled over away getting final product.
The above only is a specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
