Embodiment
The invention will be further described with the following Examples.
A kind of retractable pen, including：Pen container 1 and pen core 3, the front end of the pen container 1 are provided with what is stretched out for the nib of pen core 3
Through hole, pen core 3, which is provided with card convex, the pen container 1, is provided with inner sleeve 5, and inner sleeve 5 is placed on outside pen core 3 and front end is abutted with card convex；
Pen core 3 is outer to be also socketed with spring 4, and rear end and the card convex of spring 4 offset, and front end and the pen container 1 of spring 4 offset；Inner sleeve 5 is backward
Extend coaxial spacing ring 6, the external diameter of spacing ring 6 is less than the external diameter of inner sleeve 5, and the middle part of the pen container 1 is provided with perforation 11,
Elastic component 2 and shackle member, elastic component 2 and shackle member connection are additionally provided with pen container 1；Elastic component 2 includes and supporting that inner sleeve 5 is abutted
Socket part 22 and the elastic portion 21 for stretching out perforation 11, when pressing elastic portion 21, abutting part 22 pushes away forward inner sleeve 5, spring 4
Compressed, the nib 31 of pen core 3 stretches out through hole, while shackle member and the clamping of spacing ring 6；When unclamping elastic portion 21, elastic portion
21 reset and stretch out perforation 11, and shackle member leaves spacing ring 6, and pen core 3 is bounced back under the thrust of spring 4 in pen container 1.
The use habit of the technical program combination pen, when in use, when people holds a pen, finger pressing elastic component 2 so that elasticity
Part 2 is deformed upon, when elastic component 2 is deformed upon, and promotes abutting part 22 to promote inner sleeve 5 to travel forward, the pushing pen refill of inner sleeve 5
3 move forward, and pen core 3 stretches out pen container 1；Have also been devised shackle member in the present embodiment, shackle member also with elastic component 2 motion and
Motion, when nib 31 stretches out, shackle member is moved to the position with the clamping of spacing ring 6 so that spacing ring 6 is limited, so that
Obtain pen core 3 to be limited, it is to avoid pen core 3 controls shakiness.When elastic portion 21 is unclamped, elastic portion 21 is resetted, and shackle member is also reset to
Away from spacing ring 6, spacing ring 6 is liberated, under the thrust of spring 4, and pen core 3 and inner sleeve 5 reset, the nib 31 of pen core 3
It is contracted in pen container 1.Reach：When writing, the nib 31 of pen core 3 is stretched out and fixed, and when not writing, the nib 31 of pen core 3 is retracted
To pen container 1, pen core 3 is protected.
Further, the elastic component 2 also includes the rear collar 26, and the rear collar 26 is placed on outside pen core 3 and in pen container 1,
The collar 26 is abutted or is fixedly connected with pen container 1 afterwards.
To ensure elastic portion 21 when pressed, the abutting part 22 of elastic component 2 is moved forward, therefore the rear end of elastic component 2
Need to be positioned, prevent the deformation of elastic component 2 from occurring end behind.In the specific implementation, the rear collar 26 can be with the mistake of pen container 1
It is full of cooperation；Spacing block set can also be provided with pen container 1, spacing block set is abutted with the rear collar 26.
Yet further, the elastic portion 21 includes the shell fragment that middle part is bent outwardly, and front end and the abutting part 22 of shell fragment connect
Connect.
The rear end of shell fragment can be affixed directly to pen container 1；The rear collar 26 can also be connected to.Shell fragment when pressed, bullet
Piece is deformed upon, and the rear end of shell fragment is fixed, thus can only front end deform upon displacement, and promote inner sleeve 5 to move forward.
Further, shackle member includes the clamping block 8 and clamping spring 9 being arranged in pen container 1, and clamping spring 9 is socketed on
Clamping block 8, the pen container 1 is provided with the mounting groove being engaged with caking block, and the shell fragment, which is provided with, is used for the through hole that clamping block 8 is inserted
23, the front end of the clamping block 8 is provided with oblique projection 81, and oblique projection 81 is provided with front bevel 82, the front end of the shell fragment be provided with it is oblique
The pushing block 24 that projection 81 is engaged, pushing block 24 is provided with the back bevel 25 being engaged with front bevel 82.
When shell fragment is pressed, the front end of shell fragment is moved forward, until through hole 23 is oppositely arranged with clamping block 8, clamping block 8
End under the thrust of clamping spring 9 through through hole 23 and with the clamping of spacing ring 6；When the pressure release of shell fragment, shell fragment is multiple
Position, the front end of shell fragment is backward and outer mobile, the front bevel 82 of oblique projection 81 of the back bevel 25 of pushing block 24 and clamping block 8 on shell fragment
Offset, and clamping block 8 is pushed away to the sidewall direction of pen container 1, until clamping block 8 is separated with spacing ring 6.
By shackle member come clamping spacing ring 6 and fixed pen core 3, it is to avoid unstable phenomenon occurs in writing for pen core 3.
Further, the shackle member is the interior projection 10 for being arranged at shell fragment medial surface；When shell fragment is pressed, shell fragment hair
Raw deformation, interior projection 10 is gradually moved to the center of pen container 1, and spacing ring 6 is gradually moved forward, until interior projection 10 and spacing ring 6
End face abut；When the pressure release of shell fragment, shell fragment resets, and interior projection 10 leaves spacing ring 6.
In the technical program, shackle member is arranged on shell fragment, is subjected to displacement with moving for shell fragment.Play clamping pen
The effect of core 3.
Further, the rearward end of pen container 1 is covered provided with fixed.
Fixed lid is set, for pen container 1 to be opened, can be used for placing pen core 3 etc..
Further, the leading section of pen container 1 is provided with taper positioning tube, and taper positioning tube is threadedly coupled with pen container 1.
Set after taper positioning tube, the effect of fixed nib 31 can be played, while pen container 1 can be opened, it is convenient to install
Pen core 3 etc..
Embodiment not limiting the scope of the invention, although having made in detail to the present invention with reference to preferred embodiment
