In preferred version of the present utility model, described dental scaler, wherein, axis hole on described curved bar, the power transmission shaft and the axis hole on the driven shaft are three.
Described dental scaler, wherein, described curved bar is made by metal material.
Owing to adopt above-mentioned technical scheme, adopt curved bar to connect between power transmission shaft of the present utility model and the driven shaft, the inner end of driven shaft is erected on the curved bar, and the head of shell does not need to form a lobe, keeps the slyness of case head, and is comparatively comfortable during use.
This utility model changes the angle of the whole bearing of trend of curved bar, can change the angle that is provided with of power transmission shaft and driven shaft, and is not limited to 90 degree.
Adopt curved bar to connect between power transmission shaft of the present utility model and the driven shaft, during high speed rotating, can not skid, also can not dally.
Part of the present utility model is few, no metal injection part, and difficulty of processing is relatively low, and cost is lower, assembles simple relatively.

The specific embodiment
For further setting forth this utility model is to reach technological means and the effect that predetermined purpose is taked, see also following about detailed description of the present utility model and accompanying drawing, believe the purpose of this utility model, feature and characteristics, should obtain thus going deep into and concrete understanding, yet drawings and embodiments only provide reference and explanation usefulness, are not to be used for this utility model is limited.
To shown in Figure 7, a kind of dental scaler comprises shell 31, power transmission shaft 32, driven shaft 33, three curved bar 36 and the grinding heads 4 that adopt steel wire to make as Fig. 5; Power transmission shaft 32 is provided with three axis holes 321 near the end face of driven shaft 33, and driven shaft 33 also is provided with three axis holes 331 accordingly near on the end face of power transmission shaft 32, referring to Fig. 9; One end of curved bar 36 is actively plugged in the axis hole 321 of power transmission shaft 32 not plug-in mounting at the bottom of the hole of this axis hole 321, the other end of curved bar 36 is actively plugged in the axis hole 331 of driven shaft 33 also not plug-in mounting at the bottom of the hole of this axis hole 331, and curved bar 36 is connected power transmission shaft 32 with driven shaft 33 and interlock and integral installation are located in the shell 31; Grinding head 4 detachably is sleeved on the driven shaft 33 and connects interlock.
As shown in Figure 9, when power transmission shaft 32 rotates, wherein an end of a curved bar is when the A point forwards the B point to, and its other end just forwards the D point to from the C point, thereby driving driven shaft rotates, the insertion depth of the depth ratio curved bar of axis hole 321,331 is dark, so when power transmission shaft 32 and driven shaft 33 rotations, curved bar 36 can freely put in axis hole 321,331 and contract, thereby make that rotation is smooth and easy, to shown in Figure 12, is that a curved bar rotates 0,90,180 when spending, the situation of freely stretching of curved bar as Figure 10.
As shown in figure 10, when power transmission shaft and driven shaft all were in 0 degree position, curved bar 36 inserted in the axis hole 321,331 situation respectively as shown in the figure.
As shown in figure 11, when power transmission shaft and driven shaft all turn to 90 degree positions, curved bar 36 insert respectively in the axis hole 321,331 than the depths, situation is as shown in the figure.
As shown in figure 12, when power transmission shaft and driven shaft all turned to 180 degree positions, curved bar 36 inserted the almost bosom in the axis hole 321,331 respectively, and situation as shown in the figure.
When power transmission shaft 32 and driven shaft 33 not stalls were moving, curved bar 36 was according to the difference of turning radian, and the degree of depth of inserting axis hole 321,331 is also different.Because the limiting point that the degree of depth of axis hole stretches into greater than curved bar, so curved bar can freely stretch when rotating neatly very much.
As known by the technical knowledge, this utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in this utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
