The content of the invention
In view of this, the purpose of the present invention is in view of the shortcomings of the prior art there is provided a kind of spanner, by the way that tradition is universal
Section carries out collocation design with steering mechanism, makes the operating radius of the present invention at 90-135 ° or so, meets all bolts of power regulation station
Dismounting need.
To reach above-mentioned purpose, the present invention uses following technical scheme：
A kind of spanner, including head rod and steering mechanism, rotate connection first rotating shaft in the head rod, and described the
One end of one rotating shaft sets universal joint, and the steering mechanism includes shell and the first bevel gear being arranged in shell, second
Bevel gear, the first bevel gear coaxially fixes the second rotating shaft, one end of second rotating shaft stretch out after shell with universal joint
Other end is fixedly connected, and the first bevel gear and second bevel gear are connected by meshing transmission, and the second bevel gear is coaxially solid
Surely the 3rd rotating shaft is connected, one end of the 3rd rotating shaft sets sleeve after stretching out shell.
Further, the universal joint is cross shaft rigid universal joint.
Further, the 3rd rotating shaft and sleeve clamping, grafting or threaded connection.
Further, in addition to motor, the output shaft of motor and first rotating shaft grafting or threaded connection.
Further, in addition to operation handle, the operation handle and first rotating shaft grafting or threaded connection.
Further, the operation handle outer wall sets anti-slip veins.
Further, the end of sleeve sets dodecagon blind hole.
Further, the side wall of sleeve, which sets to run through in six tapped through holes, the tapped through hole, is threaded bar, institute
The bearing of trend for stating threaded rod is vertical with the axis of sleeve, and top plate is installed in one end that the threaded rod is located in sleeve, described
One end that threaded rod is located at outside sleeve sets cross or flat recess.
The beneficial effects of the invention are as follows：
1. the present invention includes rotating connection first rotating shaft in head rod and steering mechanism, head rod, first rotating shaft
One end sets universal joint, and steering mechanism includes shell and the first bevel gear, the second bevel gear that are arranged in shell, the first cone
Gear coaxially fixes the second rotating shaft, and one end of the second rotating shaft is fixedly connected after stretching out shell with the other end of universal joint, and first
Bevel gear and second bevel gear are connected by meshing transmission, and second bevel gear is fixedly and coaxially connected the 3rd rotating shaft, one end of the 3rd rotating shaft
Sleeve is set after stretching out shell；
When in use, the present invention can provide power to this structure by operation handle or motor, operation handle or motor
Output shaft and first rotating shaft grafting or threaded connection, set universal joint, universal joint can between head rod and steering mechanism
To use the structure of constant speed or non-constant speed, 0-35 ° of spherical rotation is realized, then passes through vertically disposed first cone of steering mechanism
Gear and horizontally disposed second bevel gear carry out 90 ° of conversions, so the angle that the present invention is adapted in 90-135 ° is used, through reality
Border is investigated, and power transformation stage space is most narrow, be most difficult to dismounting is fixing bolt on disconnecting switch base, it is necessary to by sleeve flexibility
Increasing to 100 degree could be dismantled.
2. the preferred cross shaft rigid universal joint of universal joint in the present invention, cross shaft rigid universal joint is by universal joint
The parts such as fork, cross axle, needle bearing, oil sealing, set letter, bearing cap are constituted, and operation principle is：Rotate one of fork and then pass through cross
Axle drives another fork to rotate, while can in any direction be swung around spider center, while relatively other kinds of firm again
Property universal joint, such as curved grooved type, Rzeppa constant velocity joint, cross shaft rigid universal joint has the advantages that small volume, more suitable
The present invention is closed using in power equipment more narrow environment, the practicality of the present invention is effectively improved.
3. the 3rd rotating shaft and sleeve clamping, grafting or threaded connection, this structure design can be according to required dismounting
Bolt sizes carry out quick-replaceable, further improve the practicality of the present invention, what need to be pointed out can be set in the 3rd roller end
Spring adds the positioning joint structure of steel ball, can both make collet head fast-falling, and spring and steel ball can ensure sleeve pipe in work again
It will not fall off during work.
4. the last of installation bolt or demounting bolt start be required for applying larger active force to bolt,
For stability of the increase present invention during force, anti-slip veins are set in operation handle outer wall, hand and handle can be effectively increased
Between frictional force.
5. the present invention sets dodecagon blind hole in the end of sleeve, effectively overcome and made due to the limitation of working space
The problem of being forbidden into sleeve with bolt socket.
6. set in the side wall of sleeve in six tapped through holes, tapped through hole through being threaded bar, threaded rod prolongs
Stretch that direction is vertical with the axis of sleeve, top plate is installed in one end that threaded rod is located in sleeve, threaded rod is located at one outside sleeve
End sets cross or flat recess, can adjust the distance that six top plates are stretched into sleeve when using by screwdriver, make top plate with
Bolt is in contact, so as to realize that suitable various sizes of Bolt dismantling is used.
In summary, the present invention substantially meets power regulation station not by the mutual cooperation of traditional universal joint and rotating mechanism
Same position, the dismounting demand of the bolt of different model, reduce the activity duration, save manpower.
