Abstract

The utility model discloses a pen type optic fibre cutting knife, it includes interior pen container, the outer pen socket, cutting knife platform, cuts knife face, spring, the cutting knife face lies in cutting knife platform bottom, the cutting knife platform fixed mounting be in interior pen container bottom, interior pen container cup joint in inside the outer pen socket, the spring both ends are connected respectively interior pen container top with outer pen socket inside of the top of, outer pen socket lateral wall lower extreme is opened has a displacement window, interior pen container corresponds the fixed mounting of displacement window department has horizontal bar form button, the button stretches out the displacement outside window and can reciprocate in the displacement window. Use this kind of pen type optic fibre cutting knife, damage the cutting knife face when can the prevent cutting sword falling and when not using.

Description

Pen type optical fiber cutter

Technical field

The utility model relates to a kind of optical fiber cutter, especially pen type optical fiber cutter.

Background technology

Pen type optical fiber cutter on market is all that cutter table is arranged on pen container, and the pen cap entangles pen container, opens the pen cap during use, puts the pen cap when not using.When accidentally falling in use or do not have the cover pen cap to be placed on somewhere, be easy to damage cutting knife face, extreme influence result of use and serviceable life.

Utility model content

The technical problems to be solved in the utility model, when pen type optical fiber cutter falls in use accidentally or no cover pen cap is not placed on somewhere, is easy to damage cutting knife face, extreme influence result of use and serviceable life.

The utility model is the technical scheme solving the problems of the technologies described above employing:

A kind of pen type optical fiber cutter, described pen type optical fiber cutter comprises interior pen container, the outer pen cap, cutter table, cutting knife face, spring, described cutting knife face is positioned at bottom described cutter table, described cutter table is fixedly mounted on bottom described interior pen container, it is inner that described interior pen container is socketed on the described outer pen cap, described both ends of the spring is connected to described interior pen container top and described outer pen cap inside top, described outer pen cap lower sidewall has a displacement window, the corresponding described displacement window place of described interior pen container is installed with horizontal stripe shape button, described button stretches out described displacement and also can move up and down in described displacement window outside window.

In described pen type optical fiber cutter, described cutting knife face is the oblique knife face tilted towards described displacement window.

In described pen type optical fiber cutter, described outer pen cap inner sidewall upper portion is provided with a stop annular projection portion.

In described pen type optical fiber cutter, described button Face is uneven surface.

Pen type optical fiber cutter described in the utility model fall when using state or release button time, now spring makes cutting knife face bounce back in the outer pen cap due to elastic force toward interior pen container of pulling back, can prevent damage cutting knife face.

Accompanying drawing explanation

Fig. 1 is the vertical section structure schematic diagram of pen type optical fiber cutter when not using;

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1, pen type optical fiber cutter of the present utility model comprises interior pen container 3, the outer pen cap 2, cutter table 4, cutting knife face 7, spring 1, described cutting knife face 7 is positioned at bottom described cutter table 4, described cutter table 4 is fixedly mounted on bottom described interior pen container 3, it is inner that described interior pen container 3 is socketed on the described outer pen cap 2, described spring 1 two ends are connected to described interior pen container 3 top and the described outer pen cap 2 inside top, the described outer pen cap 2 lower sidewall has a displacement window 6, corresponding described displacement window 6 place of described interior pen container 3 is installed with horizontal stripe shape button 5, described button 5 stretches out outside described displacement window 6 and also can move up and down in described displacement window 6.When pinning button 5 depress and exposing the outer pen cap 2 place to cutting knife face 7, can cutting optical fibre, now spring 1 is stretched.Cutter fall when using state or release button 5 time, spring 1 makes cutting knife face 7 bounce back in the outer pen cap 2 due to elastic force toward interior pen container 3 of pulling back, can prevent damage cutting knife face 7.Described cutting knife face 7 is preferably the oblique knife face tilted towards described displacement window 6, is so more conducive to user's operation.The described outer pen cap 2 inner sidewall upper portion is preferably provided with a stop annular projection portion 8, when can prevent spring retraction so interior pen container particularly button impacted.Described button 5 surface is preferably uneven surface, and such user easily pins button 5 and down operates, can not slippage.

The above introduction of technological means being only embodiment of the present utility model and using, be not to restriction of the present utility model, be all considered as being included within technology category of the present utility model according to disclosure herein and illustrate that any change, the equivalence done is replaced, improvement etc.
