Product.
Preferably, the line part end laminating ball is provided with some support chips, the support chip circumference array is set
In line part end.
By using above-mentioned technical proposal：After installing, support chip can increase the contact surface of line part and ball
Product, the stable pressing for realizing ball, while support chip can play limitation to motion of the ball in cavity, it is ensured that ball is only
It can be moved along the length direction of line part, it is out of ink very smooth during writing.
Preferably, the oil inlet pipe is a shoulder hole, the diameter close to ball part is minimum.
By using above-mentioned technical proposal：Because the diameter of oil inlet pipe differs larger with the internal diameter of ink tube, ink is entering
Oil pipe is easily accumulated with ink tube junction, and oil inlet pipe is arranged into shoulder hole, and shoulder hole can play a transition work
With, it is ensured that ink very smoothly can enter in oil inlet pipe, write very smooth.
Preferably, the one end of the oil inlet pipe away from ball is inwardly projecting to form spacing salient point.
By using above-mentioned technical proposal：Spacing salient point can be with spring end abutment, realize spring in oil inlet pipe
Fixation, it is simple in construction, install it is very convenient, moreover, after installing, spring stress is visibly homogeneous, can play very
Good fixed effect.
Preferably, the fixed tube end is provided with chamfering structure.
By using above-mentioned technical proposal：Chamfering structure is set, fixing pipe can be facilitated to insert in ink tube.Install very
It is convenient.
Preferably, the small middle node of both ends of the spring pitch is away from big.
By using above-mentioned technical proposal：After installing, both ends of the spring is apart from close, and intermediate distance is dredged, such bullet
Spring two ends due to that can support mutually, the deformation quantity diametrically occurred will very little, spring can be avoided to cross main convex
Point, causes spring to be dropped out out of fixing pipe.
In summary, the utility model has the advantages that：
1st, it is easy for installation；
