Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is described in detail by embodiment.

Refering to Fig. 2,3, for an embodiment of this utility model inertial drive hand-held tool, this inertial drive hand-held tool comprises: ring-type flywheel 30, speed increasing gear system 40, bearing element 50, handle 60 of housing 10, rotating shaft 20, and a tool heads 70.

This housing 10 has surrounding wall 13, room 14 that one first ring wall 11,1 second ring wall 12, is connected between the outer peripheral edge of this first ring wall 11 and the outer peripheral edge of this second ring wall 12, and one extends to the lining pipe 15 in this room 14 from the inner peripheral of this first ring wall 11.First ring wall the 11, second ring wall 12 is collectively forming room 14 with surrounding wall 13.This rotating shaft 20 can be rotatably arranged in this housing 10, this rotating shaft 20 has one and extends along an axial X and the first end 21 that communicate outside with this housing 10, and one extend and the second end 22 that communicate outside with this housing 10 along this axial X, this second end 22 is in contrast to this first end 21.In the present embodiment, first end 21 and the second end 21 of this rotating shaft 20 all protrudes out outside this housing 10.

This ring-type flywheel 30 is hubbed at this housing 10 around this rotating shaft 20 ground, and is positioned at this room 14.In the present embodiment, this ring-type flywheel 30 is hubbed at this lining pipe 15, this ring-type flywheel 30 has a diapire 31, and the perisporium 32 thickened along this axial X from this diapire 31 periphery, this diapire 31 has a medium pore 311, it is understood that the design of this perisporium 32 can increase the rotary inertia of this ring-type flywheel 30, this ring-type flywheel 30 is made to produce bigger inertia when rotating.

This speed increasing gear system 40 has one and is coaxially arranged at this rotating shaft 20 and is positioned at the initial gear 41 of this room 14, several points of this housings 10 be positioned at the relay gear 42 of this room 14 of being pivoted, and one is coaxially arranged at this ring-type flywheel 30 and is positioned at the final gear 43 of this room 14.This initial gear 41 on this axial X between this first and second end 21,22, this relay gear 42 intermeshes with this initial gear 41, this final gear 43 intermeshes with this relay gear 42, and the rotating speed of this final gear 43 is more than the rotating speed of this initial gear 41.

In the present embodiment, described relay gear 42 is hubbed at the inner side of this second ring wall 12 respectively, this perisporium 32 is around described relay gear 42, described relay gear 42 is made to be incorporated in the inside of this ring-type flywheel 30, each relay gear 42 has first gear part 421 engaged with this initial gear 41, and second gear part 422 engaged with this final gear 43, this initial gear 41 by the first gear part 421 of described relay gear 42 around, this final gear 43 is arranged adjacent to this medium pore 311 and around this rotating shaft 20, this final gear 43 by the second gear part 422 of described relay gear 42 around.

This bearing element 50 is arranged between the lining pipe 15 of this housing 10 and this final gear 43.In the present embodiment, this bearing element 50 is that a kind of oil-containing is from moistening lining.

This handle 60 is arranged at the first end 21 of this rotating shaft 20 removedly.

This tool heads 70 is arranged at the second end 22 of this rotating shaft 20 removedly, the present embodiment graphic in, this tool heads 70 is to make to represent with the kenel of screwdriver head, but is not limited thereto.

nullWhereby，As shown in Figure 4，When the screw tightening 100 of a bolt etc is tightened in the counterpart 200 of a nut etc by user the present embodiment to be utilized，After this tool heads 70 is connected with this screw tightening 100，I.e. may utilize and wherein one be held by this housing 10，And utilize another hands to go force to rotate this handle 60，This handle 60 is allowed to drive this rotating shaft 20 to rotate，In the process，This rotating shaft 20 is via this initial gear 41、Described relay gear 42 and this final gear 43，This ring-type flywheel 30 can be ordered about and produce rotation，Hereafter，As shown in Figure 5，User can decontrol another hands that hold this handle 60，The then effect of inertia of this ring-type flywheel 30 utilization itself，Can be via this final gear 43、Described relay gear 42 rotates this rotating shaft 20 constantly with this initial gear 41，Allow this rotating shaft 20 drive this tool heads 70 to go this screw tightening 100 and be tightened in this counterpart 200；On the contrary, when wanting this screw tightening 100 of loose unloading, user only need to rotate backward this handle 60, can reach purpose.

Via above explanation, can again advantage of the present utility model be summarized as follows:

One, this utility model is to utilize to be positioned at the ring-type flywheel 30 of this housing 10 to produce inertia, drive this tool heads 70 persistently rotating this rotating shaft 20, this tool heads 70, the first of this rotating shaft 20, two ends 21, 21 can't take up room when rotating with this handle 60, and this ring-type flywheel 30 may utilize this perisporium 32 to increase rotary inertia, effectively control this diapire 31 size in the horizontal, compared to prior art, this utility model unitary construction is fine and close, do not account for rotation space, will not occur in use surprisingly to get to periphery article or other people problem, it is easy to use.

Two, ring-type flywheel 30 of the present utility model is in addition to can producing inertia, it may have receive the effect of described relay gear 42, can effectively reduce the volume of this housing 10.

To illustrate that, the first end 21 of this rotating shaft 20 may be alternatively formed to the kenel of a handle certainly, the second end 22 of this rotating shaft 20 also can be formed directly in a tool heads certainly, that is, the hand-held tool of screwdriver that i.e. may make up a kind of integral type of this rotating shaft 20 etc itself, so, effect same as described above and effect are equally produced.

In sum, inertial drive hand-held tool of the present utility model, not only construct densification, and do not account for rotation space, it is simple to user operates with, so the purpose of this utility model really can be reached.
