Description
Technical field
The utility model belongs to a kind of Writing instrument, and being a kind of operated by rotation can make wax core stretch out or move back from opening
Return pen, more specifically, be it is a kind of using bull stick by act on worm screw make its rotation to allow worm screw drive wax core opened from penholder
The wax crayon for stretching out or retracting at mouthful.
Background technology
In the prior art, screw thread is formed on the inside of penholder, bull stick is arranged in penholder, and wax core is arranged by worm screw and is being turned
On bar, by rotating bull stick, make bull stick that worm screw be driven to be rotated along penholder inside thread, and driven by worm screw and moved down on wax core
It is dynamic, allow wax core to stretch out or retract from penholder opening, to realize writing or collection.
In concrete structure, in a tubular form, the outside of pipe forms the step there are one arc to worm screw, and at least two are formed on step
The parallel external screw thread of item；Bull stick includes a cylinder and a club, and club is arc-shaped, has groove thereon;Worm screw system
It is located at by its cylinder in the groove of bull stick, and acting on step both sides using groove edge can make step by external screw thread along interior
Threads turn.
In assembly, worm screw and bull stick system by bull stick auto-extending and are inserted into using being coordinated by the way of aligning
Penholder, meanwhile, so that the cylinder of worm screw is located just in the groove of bull stick, and step both sides are then just against on the edge of groove.
The problems of be, in automatic assembling, worm screw together with wax core system transmit, orientation is unordered, this is just
Trouble is caused for the contraposition in assembly, is easy to occur getting stuck in assembly due to not aligning and cause chaotic problem.
Invention content
The purpose of this utility model is to provide for a kind of wax crayon, it is suitable for automatic assembling, can utilize worm screw and wax core
Combination show orientation, to be adjusted in assembly, make bull stick that can accurately be docked in automatic assembling with worm screw.
What the purpose of this utility model was realized in：
A kind of wax crayon, including penholder, bull stick, worm screw and wax core；Wherein：Internal thread is formed on the inside of penholder；Bull stick
There are one cylinder and a clubs for tool, and club is arc-shaped, have groove thereon；In a tubular form, worm screw outside is in centre for worm screw
Part forms the step there are one arc, and at least two parallel external screw threads are formed on step；Bull stick is arranged in penholder；Wax
Core one end is fixed with worm screw, and worm screw cylinder is set on the groove of bull stick, and the external screw thread of worm screw is then in the interior spiral shell of penholder
In line；Its main feature is that：On worm screw through-hole is provided among the front of the upper and lower part of step；Wax core is fixed with worm screw, the face of wax core
Color can expose from the through-hole of worm screw.
In this way, since through-hole is located at the positive centre of worm screw, and the color of wax core can be exposed from the through-hole of worm screw, in
It is that worm screw can be identified together with wax core orientation residing in automatic assembling transmission process, so that mounting process can be adjusted
Section avoids the appearance got stuck to can guarantee that bull stick can be docked accurately with worm screw, is conducive to improve the efficiency manufactured.
Description of the drawings
Fig. 1 is a kind of schematic diagram of specific implementation mode structure of the utility model；
Fig. 2 is the schematic diagram of Fig. 1 wax crayon techniques assembling；
Fig. 3 is the schematic diagram that the worm screw back side is amplified in Fig. 1 wax crayons.
Specific implementation mode
Detailed description is made to the utility model specific embodiment below in conjunction with the accompanying drawings：
Referring to FIG. 1, FIG. 2 and FIG. 3, the wax crayon of present embodiment, including penholder 1, bull stick 2, worm screw 3, wax core 4 and
Pen tip 5；Wherein：The inside of penholder 1 is formed with internal thread 11；There are one cylinder 21 and a club 22, clubs for the tool of bull stick 2
It is arc-shaped, there is groove 22a thereon；In a tubular form, 3 outside of worm screw forms the step 31 there are one arc to worm screw 3 in middle section,
At least two parallel external screw thread 31a are formed on step 31, on worm screw 3 in the upper and lower part of step 31 32 and 33 fronts
Between be provided with through-hole b；5 end of pen tip is provided with opening；
When automatic assembling, by the assembly of pen tip 5 on the end of penholder 1；Wax core 4 is allowed to be fitted into penholder 1；Worm screw 3 is allowed to be placed on
On the end of wax core 4, make the color of wax core 4 that can expose from 3 one of through-hole b of worm screw；By being supervised to through-hole b
It surveys, adjusts the orientation of worm screw 3；It allows bull stick 2 to be inserted into penholder 1, makes the cylinder 34 of worm screw 3 just at the groove 22a of bull stick 2
Place, and the external screw thread 31a of worm screw 3 is then in the internal thread 11 of penholder 1.
