Further, the metal needle shaft lower end is thick, and upper end is thin.
Further, the plastic shaft and attachment screw junction installation spring shim.
Further, the plastic shaft is arranged to multi-diameter shaft.
Compared with prior art, the utility model has the advantages that：
1st, the utility model device metal needle shaft is arranged in the hole of plastics axis center, and pointer and stars metal dish are arranged on
On metal needle shaft and plastic shaft, and pivot is consistent, and dress pointer can be achieved and dress metal star disk is androgynous, without using two
Part, and the position for filling metal star disk is realized with plastics, solves the problems, such as the difficult dress of metal to metal, save part and
Process, cost is reduced, simplify the difficulty of process.
2nd, the utility model device plastics gear piece and plastic shaft are integrally formed, and metal needle shaft vertical press-fit is in plastics gear piece
The heart, three form a component, are vertically loaded on star disk in plastic shaft, it is necessary to fill pointer when needing to fill metal star disk
When by metal finger loaded on metal needle shaft, can also realize what star disk and pointer assembled simultaneously, make movement function more.
3rd, the lower end of the utility model device metal needle shaft is provided with thread cap, passes through plastics gear piece bottom stator and company
The design of screw is connect, further fixed effect can be played to metal needle shaft and thread cap, prevents metal needle shaft and plastic shaft
There is the phenomenon slid when not fastening in interior internal thread threaded connection, when metal needle shaft and plastic shaft need not be co-axially mounted,
Dismounting for metal needle shaft is more convenient, goes for more occasion.

Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As Figure 1-3, a kind of multifunctional gear component, including metal needle shaft 1, plastic shaft 2 and plastics gear piece 5, it is described
Plastic shaft 2 and plastics gear piece 5 is integrated is process, the center of plastic shaft 2 is provided with hole, and the metal needle shaft 1 is arranged on
In the hole at the center of plastic shaft 2, the lower end of the metal needle shaft 1 is provided with thread cap 6, and in the thread cap 6 and plastic shaft 2
Internal thread hole is threadedly coupled, and the bottom of the thread cap 6 is fixed by stator 4, and the stator 4 passes through attachment screw 3
The bottom of plastic shaft 2 is fixed on, the metal needle shaft 1 is made of metal material, and the plastic shaft 2 and plastics gear piece 5 use
Plastic material is made.
The utility model multifunctional gear component, by the design to plastic shaft 2, metal needle shaft 1 is arranged in plastic shaft 2
In the hole of the heart, pointer and stars metal dish are arranged on metal needle shaft 1 and plastic shaft 2, and pivot is consistent, and achievable dress refers to
Pin and dress metal star disk are androgynous, and without using two parts, and the position for filling metal star disk realizes solve with plastics
The problem of metal to metal hardly possible dress, part and process are saved, reduces cost, simplifies the difficulty of process, the He of plastics gear piece 5
