Two raised platforms, 14. compression springs.
Fig. 1 to Fig. 3 shows a kind of the first embodiment of pen meter of universal meter of the present invention.As shown in figures 1 and 3, should
Pen meter of universal meter includes pen body 1, nib 2 and wire 3, and wire 3 connects pen body 1, and pen body 1 connects nib 2.Covered in the pen body 1
Provided with protective cover 4, protective cover 4 connects rubber sleave 5, and the first external screw thread 6 and the second external screw thread 7 are respectively equipped with the both ends of pen body 1,
The both ends of protective cover 4 are respectively equipped with the 3rd internal thread 8 and the 4th internal thread 9, and the first external screw thread 6 and the 3rd internal thread 8 are set respectively
In pen body 1 and the left end of protective cover 4, the second external screw thread 7 and the 4th internal thread 9 are separately positioned on pen body 1 and the right-hand member of protective cover 4,
Pen body 1 is linked together with protective cover 4 by the second external screw thread 7 with the 3rd internal thread 8, because the diameter of pen body 1 is more than rubber
The bore of the left end opening of leather sheath 5, pen body 1 can not be passed through rubber sleave 5, so as to which pen body 1 will not separate with protective cover 4.
As shown in figure 1, when assembling pen meter of universal meter, protective cover 4 is rotatably connected in pen body 1, nib 2 is adjusted to
The correct position of sealing station 10.Now, nib 2 will not accidentally injure people, will not also be damaged.For the pen meter of universal meter of this assembling,
Even if being dropped in carrying process, the fit structure of the 3rd internal thread 8 of the second external screw thread 7 and protective cover 4 of pen body 1 serves limit
The effect that nib 2 processed moves to the direction of sealing station 10, thus nib 2 will not be made through the through hole 11 on sealing station 10, so as to not
Nib 2 can be damaged., can be with as shown in Fig. 2 rotation protective cover 4, protective cover 4 be by screw thread guide when using pen meter of universal meter
The direction of line 3 is moved, and the rubber sleave 5 positioned at the lower end of protective cover 4 will move with the direction of 4 guiding line of protective cover 3, rubber sleave 5
It can be set on wire 3, meanwhile, nib 2 can be such that pen body 1 is overlapped with protective cover 4 through the through hole 11 on sealing station 10, so as to
First external screw thread 6 is connected with the 3rd internal thread 8, and the second external screw thread 7 is connected with the 4th internal thread 9, and staff holds protective cover 4
Operation.
Fig. 4 to Fig. 6 shows a kind of second of embodiment of pen meter of universal meter of the present invention.With the first embodiment
The main distinction is that it is not to limit the motion of the direction of 4 guiding line of protective cover 3 using thread matching structure completely, but is used
First external screw thread 6 and protective cover 4 on the compression spring 14 and pen body 1 being provided between the raised platforms 12 of sealing station 10 and first
On the fit structure of the 3rd internal thread 8 come limit the direction of 4 guiding line of protective cover 3 motion.It is corresponding in this, the second of pen meter of universal meter
Kind embodiment eliminates the second external screw thread 7 and the 4th internal thread 9 relative to the first embodiment, and increases in the right-hand member of pen body 1
If the first raised platforms 12 and in the left end of protective cover 4 being additionally arranged the second raised platforms 13.As shown in Figure 4 and Figure 6, sealing station 10
Compression spring 14 is provided between the first raised platforms 12, compression spring 14 is set on nib 2.As shown in figure 4, under normality,
Compression spring 14 limits the direction motion of 4 guiding line of protective cover 3.For the pen meter of universal meter so assembled, it is in carrying process
Make to drop, engage the second projection provided with the raised platforms 12 of compression spring 14 and first between sealing station 10 and the first raised platforms 12
The fit structure of platform 13 moves left and right to limit protective cover 4, thus will not make through hole 11 of the nib 2 through on sealing station 10,
So as to which nib 2 will not be damaged.When using pen meter of universal meter, can with as shown in figure 5, press down on the sealing station 10 of protective cover 4,
Nib 2 can be through the through hole 11 on sealing station 10, and the rubber sleave 5 positioned at the lower end of protective cover 4 will be with the guiding line 3 of protective cover 4
Direction is moved, and rubber sleave 5 can be set on wire, and then gently rotating protective cover 4 makes it be overlapped with pen body 1, so as to first
External screw thread 6 is connected with the 3rd internal thread 8, and staff holds protective cover 4 and operated.
