The hollow connecting cylinder 9 closed and the gear sleeve 7 for driving hollow connecting cylinder 9 to rotate；It is provided in handle 2 and gear sleeve
7 transmission shafts 4 being drivingly connected, the limit assembly of 7 direction of rotation of adjustment gear sleeve is additionally provided on spanner shell 1；The utility model
It is a kind of spanner with rotation torque using the strong applicability of transfers, when in use, until needing that transmission shaft 4 is driven to revolve
Turn, then drive gear sleeve 7 to rotate by transmission shaft 4, to drive the hollow connecting cylinder 9 being connected with gear sleeve 7 to rotate, in this way
The screw nut coordinated with hollow connecting cylinder 9 can be driven to screw or unclamp, user only needs hollow connecting cylinder 9 and spiral shell
Silk nut cooperation compares conventional spanner, it can be operated in more narrow space without rotating handle 2；When
So, it can also realize the rotation of spanner shell 1 as conventional spanner using the torque that handle 2 generates, if spanner shell 1 with
Corresponding spline structure, such as rotation stop pin are set between gear sleeve 7 or hollow connecting cylinder 9；Certainly, it is controlled to improve operation
The convenience of system is also additionally provided with the limit of 7 direction of rotation of adjustment gear sleeve according to the needs that spanner operates on spanner shell 1
Component can be needed according to screw nut is elastic through the clamping matching of limit assembly and gear sleeve 7 limit before spanner operation
Its rotation direction is made, to avoid maloperation, improves the efficiency that spanner uses；Certainly, for the ease of safeguarding, the spanner shell 1
It can be split structure, that is, use by two fixed cylindrical structures of dismountable splice.
The key structure of the utility model is the connection structure of transmission shaft 4 and gear sleeve 7 and the knot of limit assembly
Structure designs, and in the specific implementation, the gear sleeve 7 is rotatably connected by bearing 13 in spanner shell 1, and gear sleeve 7 is carried on the back
One end from hollow connecting cylinder 9 is fixed with first bevel gear pair 5, and one end of transmission shaft 4 is fixed with engages with first bevel gear pair 5
The second bevel gear pair 6 of transmission；Utilize the engaged transmission of first bevel gear pair 5 and second bevel gear pair 6 accurate high in this way
Transmission shaft 4 is passed to gear sleeve by effect ground, realizes the reliable delivery of turning moment；And meet the axis of gear sleeve 7
It is needed with the vertically arranged structure of axis of transmission shaft 4；In an installation, being provided between transmission shaft 4 and handle 2 makes transmission shaft 4
It is capable of the bearing 13 of smooth pivotal, for the ease of being connect with other tool transmissions, the transmission shaft 4 deviates from the one of gear sleeve 7
The section at end is hexagonal structure.
In the specific implementation, the limit assembly includes about the symmetrical two direction of rotation limit of 7 axis of gear sleeve
Position pin 10, as shown in Fig. 2, gear sleeve 7 is equipped with the rotation adjustment gear 8 with 10 clamping matching of direction of rotation spacer pin,
Direction of rotation spacer pin 10 is also associated with for adjusting two direction of rotation spacer pins 10 and rotating 8 detent position of adjustment gear
Limit direction release handle 12；In order to improve limit accuracy, it is also connected between described two direction of rotation spacer pins 10 and spanner shell 1
There is the spring 11 for driving two direction of rotation spacer pins 10 close；In assembly, first by gear sleeve 7, (middle waist is that rotation is adjusted
Section gear 8) both ends respectively put on a bearing 13 and are put into spanner shell 1,7 flexible rotating of entire gear sleeve can be enable in this way, then
It is put into left and right spacer pin 10, two spacer pins are sandwiched between a limit direction release handle 12, left and right direction of rotation spacer pin 10
A spring 11 is respectively filled between 1 inner wall of outside and spanner shell, so that direction of rotation spacer pin 10 is inwardly squeezed, covers head cover, is twisted
It tightens up a screw with fixing head lid, the convex block outside covering is extended by limiting direction release handle 12, when stirring limit direction release handle 12,
Since limit direction release handle 12 works with spring 11 and makes two direction of rotation spacer pins 10 that can move to left and move to right simultaneously, when pin to
As soon as side moves, there is a direction of rotation spacer pin 10 unidirectionally to lock the rotation adjustment gear 8 of waist in gear sleeve 7, revolving
When turning screw nut, the direction of rotation spacer pin 10 that swings can make entire gear sleeve 7 just be single direction rotation, user therewith
Just flexibly, certainly since the utility model is adopted as hollow connecting cylinder 9, the dismountable hollow of multiple sizes can be matched as needed
Collet head；Hollow connecting cylinder 9 is driven to rotate by the rotation of the transmission shaft 4 among handle, this axial direction kind of drive is existing
There is the structure type that spanner does not have, i.e. the pinch bar still can the comprehensive rotation in left and right in the environment of not moving left and right
Screw nut, applicability are good.
In order to further increase the reliability and stability used, the utility model is also optimized its detailed structure
Design, wherein handle 2 are additionally provided with the turnbarrel 3 being drivingly connected with transmission shaft 4 away from one end of spanner shell 1；The turnbarrel 3
Rotation driving transmission shaft 4 rotates, and certainly, in order to time saving and energy saving, motor drive transmission shaft 4 can also be utilized to rotate；Rotary sleeve
The torque overload protector for limiting the maximum rotation torque of turnbarrel 3, the torque are also associated between cylinder 3 and transmission shaft 4
A torque sleeve being set between rotaring sleeve 3 and transmission shaft 4 can be used in overload protective device；Torque overload protector can revolve
Rotaring sleeve 3 reaches automatic tripping when mobile degree, and turnbarrel 3 is avoided to bear Overload torque and destroyed by structure, can be effective
