In this invention, increase device 40 by revolving force and transmit the revolving force of carrier wheels 63 to final output shaft 45, showing 2 revolving forces down increases the relevant example of devices 40.
First example: revolving force increases device 40 as shown in Figure 1, inner cylinder length direction by internal gear 11[cover 10, form at partial section], first swivel plate 41[cover 10 is for rotary setting], the multiple first pinion gear 43[combines with internal gear 11 tooth prefaces in order to convey carrier wheel 63, with pivot pin 42 is media, the cylinder direction rotation at the position, the place ahead of first swivel plate 41], ledge in the heart in central gear 44[the 1st swivel plate 41 back sides], the 2nd swivel plate (can be in cover 10 inner rotations, be positioned at the end of the final output shaft 45 corresponding with central gear 44, isolate with the 1st swivel plate 41), multiple the 2nd pinion gear 43 ' [combines with central gear 44 common tooth prefaces, gives the 11 tooth preface combinations of internal gear position simultaneously, with pivot pin 42 ' is media, the cylinder direction rotation at the position, the place ahead of the 2nd swivel plate 41] constitute.
Revolving force increases in the 1st swivel plate 41 of device 40, the pivot pin 42 and the 1st swivel plate that can allow the 1st pinion gear 43 rotate are one, it is the part of giving prominence to, in the 2nd swivel plate 41 ', the pivot pin 42 and the 1st swivel plate that can allow the 2nd pinion gear rotate are one, be the part of giving prominence to, but not explanation in addition on the drawing.
And revolving force increases in the 1st swivel plate 41 of device 40, the pivot pin 42 and the 1st swivel plate that can allow the 1st pinion gear 43 rotate are one, are the parts of giving prominence to, in the 2nd swivel plate 41 ', the pivot pin 42 and the 1st swivel plate that can allow the 2nd pinion gear rotate are one, are the parts of giving prominence to.(with reference to figure 1) do not have the symbol 46 the introduced binding site at final output shaft 45 here, can combine with the angle-shaped groove 51 of an end of pullover 50.
To introduce the effect of the revolving force increase device 40 in first example in the present invention's product below.
At first carrier wheel 63 is clockwise or when being rotated counterclockwise, and majority the 1st pinion gear that combines with carrier wheel tooth preface can be with rotation simultaneously, revolution around the carrier wheel.When most the 1st pinion gear 43 rotations were revolved round the sun simultaneously, the 1st swivel plate 41 can be with most the 1st pinion gear 43 equidirectionals rotations.In this process, the gear ratio of carrier wheel 63 and the 1st pinion gear 43, at first speed can change (deceleration), and the 1st swivel plate 41 and power shaft 60 the earliest can be with low speed rotation, but revolving force can increase.During 41 rotations of the 1st swivel plate, can be at the central gear 44 of this installation with the direction of rotation rotation of the 1st swivel plate 41.During central gear 44 rotations, majority the 2nd pinion gear 43 that combines with these central gear 44 tooth prefaces ' automatically simultaneously can be around central gear 44 revolution.
' revolution simultaneously automatically, the 2nd swivel plate 41 ' can be with the identical direction rotation of the 2nd pinion gear 43 ' revolution direction for the 2nd pinion gear 43.
At this moment, carrier wheel 63 and the 2nd pinion gear 43 ' the gear ratio, the 2nd swivel plate 43 ' can 2 speed changes (decelerations), at first with the 1st swivel plate 41 relatively, understand with low speed rotation, but revolving force can increase.So as first example of the present invention, increase the formation of device 40 by revolving force, final output shaft 45 is compared with power shaft 60 the earliest, can even use very little strength, also can rotate hold-down nut with bigger revolving force rotation.Can change the direction of rotation of hold-down nut according to the direction of rotation of carrier wheel 63 in addition.
As shown in figure 10, the 1st swivel plate 41 central authorities have 5 dihedral through hole 41a in revolving force increase device 40 structures, are combined in the polygonal through hole 41a of central gear 44, can make the joint portion 44a of 5 angular appearance.In addition as shown in figure 10, revolving force increases the 2nd swivel plate 41 in device 40 structures ' a central authorities has 5 dihedral through hole 41a, in the through hole 41 ' a of the 2nd swivel plate 41 ' that the joint portion of final output shaft 45 46 is opposite, can form the joint portion 45a of 5 angular appearance.
In addition as shown in figure 12, operating grip 80A passes the through hole 60b of the other end of power shaft 60 the earliest, power shaft is vertical during installation with the earliest, one end of operating grip has and the pullover connecting portion that is connected 81, and the other end of operating grip 80A is installed the detachable assist handle 85 vertical with operating grip 80A.
Connect pullover reason at operating grip 80A: utilize pulloverly 50, unclamp or tighten in the process of hold-down nut,, can use temporarily if when the phenomenon of the spanner fault in this invention takes place.When using the spanner of current invention to tighten hold-down nut fully or unclamp the hold-down nut of tightening fully, hold-down nut connect pullover 50 ' state under, can use operating grip.The main purpose of operating grip 80A is the parts power shaft 60 the earliest of rotary spanner in addition.
As Fig. 1 or shown in Figure 12, operating grip does not combine with power shaft 60 the earliest, and the angle-shaped groove 60a of the other end of power shaft 60 inlet inserts the earliest, and 80a constitutes by the joint portion.That is to say can select multiple according to operating grip 80.
The 1st example of the present invention such as Fig. 1, shown in Figure 3, the outside of cover 10 is vertical with certain-length, prolongs and makes support bar, at the position, end of this support bar 15 slotted hole 151.
After inserting other fixing pullover 30 connecting screws 31 of giving prominence in the slotted hole 151, fixing pullover 30.
Fixing pullover 30 is different with above-mentioned pullover 50, are used for others.These fixing pullover 30 wheel hubs are from outstanding most fixed screw axles, and folder is one in hold-down nut, and pullover 50 in order to install at the fixed screw axle or to separate, and clamping is decided nut.
Use the reason of slotted hole: the spacing according to the vehicle hold-down nut can be different, adjust fixing pullover 30 spacing by pullover 50.
This invention utilizes other support bar 15 and fixing pullover 30, is installed in the fixed screw axle or separates from the fixed screw axle being clipped in pullover hold-down nut easily.
To introduce the effect of the example of current invention below.Here will introduce revolving force and increase device 40.
At this moment a double plate spring 71,72 of elastic device 70 is because central authorities can separate, and the jog 65 of the jog 62 of power shaft 60 and carrier wheel 63 is because of mutual concavo-convex combination, so the revolving force of power shaft 60 can rotate carrier wheel 63 the earliest the earliest.
Pullover when being completely fixed in object, do not need to use too many strength.
Install and fix nut in addition in the object fully, hold-down nut contact tire wheel surface, when no longer rotating, the user uses the operating grip 80 of a double plate spring 71,72 compression stresses of an elastic device.Rotate the earliest that power shaft 60 is, the jog 65 of the jog 62 of power shaft 60 and carrier wheel 63 breaks away from mutual concavo-convex bonding state the earliest, makes it to be in contact with one another, and according to carrier wheel 63, sky rotates power shaft 60 the earliest.(with reference to figure 7 or Fig. 8)
User's perception immediately power shaft 60 is the earliest known to install and fix nut fully according to carrier wheel 63 empty rotations.
When rotating the earliest power shaft 60 according to carrier wheel 63 skies, when the jog 62 of power shaft 60 is than jog (65 compare) contact of carrier wheel 63 the earliest, very blunt noise takes place, this noise of user's perception is known to install and fix nut fully.
As of the present invention shown in Figure 9, hold-down nut is installed in the direction of object, contact tire wheel surface, no longer under Xuan Zhuan the state, the direction that hold-down nut separates from object, contrary when rotating the earliest power shaft 60, the jog 65 of carrier wheel 63 and the earliest power shaft 60 keep mutual concavo-convex bonding state, power shaft 60 can be just in the rotation guide hole 21 of cap 20 the earliest/and contrary rotation, can utilize and control/remove the earliest that power shaft stops control/decontrol 90.
As shown in Figure 6, swingle 93 by passage 91a, makes the part of bar 93 inner outstanding from the rotation guide hole 21 of cap 21, contacts the inner face of the stop slot 94 of power shaft 60 the earliest earlier, and power shaft 60 can not advance laggard at rotation guide hole 21 the earliest.
The jog 62 of power shaft 60 and carrier wheel 63 can force to keep mutual concavo-convex bonding state the earliest, rotate power shaft 60 the earliest, the inner face of stop slot 94 is by passage 91a, and the outside of the rotation guide hole 21 inner bars of giving prominence to 93 of cap 20 not only can contact, and also can rotate carrier wheel 63.
Because the rotation of carrier wheel 63, final power shaft 60 and pullover 50 can rotate, and hold-down nut is installed in the direction of object, the contact of tire wheel surface, no longer under Xuan Zhuan the state, from the direction rotation hold-down nut that object separates, the result separates hold-down nut from object.
Revolving force of the present invention increases the 2nd example of device: as shown in figure 11, the inner cylinder length direction of cover 10 is arranged, the internal gear 11 that certain orientation forms; The front circular slab that can allow carrier wheel 63 move and rotate at central part from the back circular slab 76 that front circular slab 75 is isolated, is installed in the marginal position of front circular slab 75 and back circular slab 76.
In addition these are connected as one, gear exposes the inside cover 78 that hole 77a forms most parts 77 on every side; Combine with the carrier wheel 63 common tooth prefaces of passing the front circular slab, and in order to allow the general of gear continue to combine with internal gear 11, make it to cover 78 inside in inside, pin is that media can rotate.It is inner that part is outstanding in the gear position multiple pinion gear 79 and cover are installed in inside, makes it and can expose hole 77a rotation by gear.The end of the final output shaft 45 of circular slab 76 correspondences prolongs making in the back, makes the suspicious other parts that contain most pinion gears 79, also comprises the transposition gear 48 of the ring apperance of tooth preface combination.The gear of internal gear portion 11 connects number and lacks than the number of teeth of transposition gear then, according to the number of teeth amount difference of transposition gear 48 and internal gear 11, and the rotation of can slowing down of final output shaft 45.Have identical internal diameter though that is to say transposition gear 48 with internal gear 11, but because the difference of the number of gears, so will be according to internal gear 11, most pinion gears 79 can rotations or around the gear revolution, transposition gear 48 can rotate according to the internal gear 11 and transposition gear 48 numbers of teeth.
