The first cover board being connected with the second end of operation lever；
The intermediate spill spin block being connected on one side with first cover board；
The second cover board being connected with the another side of the intermediate spill spin block；
The concentric inside and outside tooth rotating ratchet with the intermediate spill spin block, and the inside and outside tooth rotating ratchet is mounted on described
Between first cover board and second cover board, the external tooth of the inside and outside tooth rotating ratchet and the external tooth of the inside and outside tooth rotating ratchet
Between be provided with the first attachment rail of installation ball, first cover board and second cover board are supported respectively mounted on described the
The both ends of ball in one attachment rail；
The pawl that first end and the intermediate spill spin block are rotatably connected, the second end of the pawl is compared with the pawl
First end set counterclockwise and the second end of the pawl can be with the interior tooth engagement of the ratchet.
Preferably, in above-mentioned freewheel clutch, spring is additionally provided between the intermediate spill spin block and the pawl.
Preferably, in above-mentioned freewheel clutch, connecting rod and the nested chuck being rotatably connected with the connecting rod are further included；
The nesting chuck is rotatably connected with second cover board；
The first slot is provided on the intermediate spill spin block；
The connecting rod is swung in first slot, and the first end of the connecting rod is connected with the nested chuck, described
The second end of connecting rod is connected with the pawl；
The interior tooth engagement for driving the pawl and the ratchet can be realized when the connecting rod is swung in first slot
With separating.
Preferably, in above-mentioned freewheel clutch, be provided with the second slot on the intermediate spill spin block, first slot with it is described
Second slot connects；
Arc convex is provided on the nesting chuck, and the arc convex can rotate in second slot.
Preferably, in above-mentioned freewheel clutch, pawl control chuck is further included；
The pawl control chuck is connected with the nested chuck.
Preferably, in above-mentioned freewheel clutch, pawl control-rod is further included；
The pawl control-rod is arranged on the pawl control chuck.
Preferably, in above-mentioned freewheel clutch, the pawl control-rod is arranged on the edge of the pawl control chuck.
Preferably, in above-mentioned freewheel clutch, the end set of the operation lever has tripod；
The tripod includes three cradling pieces, and the first bolt hole is provided on the cradling piece, the cradling piece and institute
It states and is connected by screw and the threaded hole between the threaded hole of three cylinders of the first cover board.
Preferably, in above-mentioned freewheel clutch, the operation lever sets the hollow structure of reinforcing rib, three institutes for inside
Cradling piece is stated in 120 degree of distributions, and the second bolt hole being connected with first cover board is provided on each cradling piece.
Preferably, in above-mentioned freewheel clutch, support institute is also provided on first cover board and on second cover board
State the second attachment rail of ball of ball.
It can be seen from the above technical scheme that freewheel clutch provided by the invention, the first cover board and the second cover board branch
Intermediate spill spin block is supportted, tooth rotating ratchet inside and outside the ball support between the first cover board and the second cover board.It is provided by the invention
Freewheel clutch when load is so that operation lever rotates counterclockwise, drives the in use, apply load to the first end of operation lever
One cover board and the second cover board rotate counterclockwise, and then intermediate spill spin block is driven to rotate counterclockwise, at this point, in the effect of centrifugal force
Under, the pawl that is connected with intermediate spill spin block can be rotated to the direction away from intermediate spill spin block so that the second end of pawl can be with
The interior tooth engagement of ratchet, and then tooth spiral turns pawl wheel inside and outside drive, realizes the tooth with the outer tooth engagement of inside and outside tooth rotating ratchet
Wheel also can be rotated synchronously and then；When load is so that operation lever rotates clockwise, drive the first cover board and the second cover board clockwise
It rotates, and then spill spin block rotates clockwise among driving, at this point, under the action of centripetal force, the spine that is connected with intermediate spill spin block
Pawl can be rotated to close to the direction of intermediate spill spin block so that the second end of pawl departs from the internal tooth of ratchet, so that interior external tooth
The external tooth of rotating ratchet stops operating, and also stops operating with the foreign steamer meshed gears of inside and outside tooth rotating ratchet.The present invention provides
Freewheel clutch, since pawl can be engaged with the internal tooth of inside and outside tooth rotating ratchet, pawl gives inside and outside tooth rotating ratchet
Internal tooth power be direct rotatory force rather than frictional force of the prior art driving force, this avoid pressure to pawl
Caused by stress concentration, big torque can be transferred, since there is no frictional force, avoid pawl and inside and outside tooth rotating ratchet it
Between abrasion.Pawl and intermediate spill spin block and the lever of the connection composition of operation lever, can both avoid stress concentration, can also transfer
Big torque.
