311 the second shaft part 3112, the side of first washer 45 are resisted against first shaft part 3111 so that first washer 45 can not
The first shaft part 3111 of the mandrel 311 is slid onto, which bears against along the opposite both ends of first axle L1
In side of first washer 45 in contrast to first shaft part 3111 with the second packing ring 47 in contrast to the second steel ball group 48
Side, more preferably, first elastic component 43 and second elastic component 46 are coil spring, and the stiffness system of second elastic component 46
Number is more than the stiffness factor of first elastic component 43.The drive link 41 in contrast to the driving section 411 one end tool there are one end
414, one end of the end 414 is connect along first axle L1 with the connecting portion 412, and the other end of the end 414 connects the horse
Up to the second shaft part 3112 of 31 mandrel 311, which includes several steel balls 481 and along the circle of first axle L1
Circumferential direction is located on the end 414 of the drive link 41 and connecting portion 412 and the second packing ring 47 and the first of the connecting hole 13
Between the internal face of linkage section 131.
Referring to Figure 10 to Figure 12, when the end tooth portion of the bevel gear 42 and first ring gear 23 and second ring gear 24
232nd, 242 engagement, the mandrel 311 of the motor 31 drive the drive link 41 to be rotated with the bevel gear 42 along first axle L1, should
Bevel gear 42 drives first ring gear 23 and second ring gear 24 along second axis L2 relative to 21 up time of spine move part respectively
Needle direction counterclockwise rotates, and with two main gear blocks 221 and the first secondary tooth block 222 or the second secondary tooth block
223 one of them drive spine move part 21 are rotated along second axis L2 so that the spine move part 21 is rotated with moving sleeve.Thereby, originally
Invention electric sleeve barrel ratchet spanner reach do not move the shank part 16 and can be by the mandrel 311 of the motor 31 along the first axle
The rotation relation of the spine move part 21 along second axis L2 is changed into L1 rotations.
Referring again to Figure 13 and Figure 14, excessive resistance is met when the motor 31 rotates and drives nut with band moving sleeve, such as：
The problem of long bolt in construction site often rusts, and nut is made to be stuck in the long bolt place of rusting and generates excessive resistance hardly possible
With rotation so that the torsion of the motor 31 is not enough to that the drive link 41 is driven to drive the spine move part 21, makes the spine move part 21 can not
Rotational sleeve, the bevel gear 42 slide with respect to the driving section 411 of the drive link 41 along first axle L1 and are detached from first tooth
The end tooth portion 232,242 of ring 23 and second ring gear 24 simultaneously compresses first elastic component 43 simultaneously, at this time due to second elasticity
46 pushing tow of the part second packing ring 47 and the drive link 41 so that the bevel gear 42 still can be against first ring gear 23 and second tooth
Ring 24, which simultaneously generates, jumps the state that can not engage of tooth, and the motor 31 persistently rotates at this time, user can hear the bevel gear 42 with
Tooth is jumped between first ring gear 23 and second ring gear 24 can not engage and hit the Da Da sounds of generation, and user can hold
It holds the shank part 16 and the second end 102 of the ontology 10 is separately pulled with manpower, the umbrella tooth is forcibly made in a manner of exerting a force manually
Wheel 42 is along second axis L2 relative to the sliding of driving section 411 of the drive link and again simultaneously with first ring gear 23 with being somebody's turn to do
Second ring gear 24 end tooth portion 232,242 engagement and cross cap rotation with moving sleeve resistance is excessive, the region such as got rusty, when
User with manpower by the excessive region of sleeve resistance after, which can reply engagement again and drive first ring gear
23 with second ring gear 24 and drive the spine move part 21 along second axis L2 rotate with band moving sleeve rotate, thereby account for one
As impersonal force drive box spanner can not solve the problems, such as that sleeve is difficult to overcome excessive resistance.
It can summarize electric sleeve barrel ratchet spanner of the present invention with regard to described above and has the following advantages：
1. the end tooth of the bevel gear 42 of electric sleeve barrel ratchet spanner of the present invention and first ring gear 23 and second ring gear 24
Portion 232,242 is engaged, and the mandrel 311 of the motor 31 drives the drive link 41 to be rotated with the bevel gear 42 along first axle L1,
The bevel gear 42 drives first ring gear 23 suitable relative to the spine move part 21 along second axis L2 with second ring gear 24 respectively
Clockwise counterclockwise rotates, and with two main gear blocks 221 and the first secondary tooth block 222 or the second secondary tooth block
223 one of them drive spine move part 21 are rotated along second axis L2 so that the spine move part 21 is rotated with moving sleeve.Thereby reach
The spine move part 21 can be changed into along first axle L1 rotations by the mandrel 311 of the motor 31 into not moving the shank part 16
Along the rotation relation of second axis L2, thus reach the effect of time saving and energy saving.
2. the extension 17 of electric sleeve barrel ratchet spanner of the present invention is along vertical first axle L1 directions tool, there are one rectangles
Cross section, reach by the setting of rectangular cross section electric sleeve barrel ratchet spanner of the present invention have flat handle structure, because flat
The circle handle structure of the relatively general existing spanner of radial direction force of handle is strong, so electric sleeve barrel ratchet spanner of the present invention has structural strength
Stronger advantage.
3. excessive resistance is met, such as the nut of sleeve connection gets rusty during electric sleeve barrel ratchet spanner band moving sleeve of the present invention,
The spine move part 21 by excessive resistance and can not rotational sleeve, the bevel gear 42 along first axle L1 with respect to the drive link 41 biography
Dynamic portion 411 slides and is detached from the end tooth portion 232,242 of first ring gear 23 and second ring gear 24 and compresses first bullet simultaneously
