The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

With reference to accompanying drawing, the utility model comprises blade 12 and handle bar 17, and the root rigidity of described one piece blade 12 is installed the rotation slurry 7 that a crank throw 13 constitutes L type structure; Described one piece blade 12 and crank throw 13 bonded assembly roots constitute the blade 12 of half leaf structure in a side of blade 12; Described handle bar 17 is hollow tube structure, and the housing 2 that is the inverted L shape structure is installed in its below, and both form the inverted T shape structure; Crossbeams 3 are installed in the described housing 2, and its two ends all are provided with and only allow crossbeam 3 axially make the crossbeam sheath 1 of finite motion along handle bar 17, and crossbeam 3 is connected with the tension mechanism 6 employing crossbeam wire drawings 5 of handle bar 17, and crossbeam wire drawing 5 is in the hollow cylindrical shell of handle bar 17; On the housing 2 of described crossbeam 3 belows, at least two employing axle 8 bonded assemblys rotation oars 7 that have torsion spring 9 are installed, each rotation oar 7 is provided with the last backstop 10 and the following backstop 11 on the housing 2 of being installed in that can limit its rotation amplitude, and crossbeam 3 rotates oar 7 with each and all adopts crank throw wire drawing 4 to be connected.

Described rotation slurry 7 is made up of axle 8, torsion spring 9, blade 12 and crank throw 13, and blade 12 and crank throw 13 are L type structure, and the through hole of installation shaft 8 is set on the crank throw 13 of L type corner, and torsion spring 9 is sleeved on spools 8; Described rotation slurry 7 usefulness axle 8 is installed on the housing 2, and an end of torsion spring 9 is fixed on the housing 2, and an other end of torsion spring 9 is fixed on the crank throw 13.

Described tension mechanism 6 is made up of lever support 14, lever 15, retracing spring 16, third wheel 18 and annex; Described third wheel 18 is installed in the end of handle bar 17; Described lever support 14 is installed in the end of handle bar 17 away from housing 2, and lever 15 is mounted thereto; The head of described lever 15 is adjacent with third wheel 18, and crossbeam wire drawing 5 is passed and straddled the head that is fixed on lever 15 behind the third wheel 18 behind the handle bar 17; The afterbody of described lever 15 is provided with retracing spring, and the two ends of retracing spring 16 are separately fixed on handle bar 17 and the lever 15.

In the present embodiment:

Described blade 12 is half impeller structure, this be because its with crank throw 13 rigidly connected roots in a side, they are during with crank throw 13 rotations, near centre of gration, so be equivalent to have only half leaf, this is the description of an image to its root again.

Described axle 8 adopts ripe prior art to make, with housing 2 for being rigidly connected, with through hole on the crank throw 13 for being rotationally connected, according to known mechanical general knowledge, it must be provided with backstop after passing through hole on the crank throw 13, as adopts the pier nose of self, perhaps other structures.

Described torsion spring 9 adopts ripe prior art to make.

Described retracing spring 16 adopts ripe prior art to make, and is compression spring.

The effect of torsion spring 9, crank throw wire drawing 4 and the crossbeam wire drawing 5 of the retracing spring 16 of tension mechanism 6, rotation slurry 7 has constituted rotation and has starched 7 self-turning mechanism, has realized the function of one group of blade 12 automatic clutch.

The utility model in use, the operator sits aboard ship, perhaps on other buoyancy aids, the right-hand man respectively holds one and half leaves rotation clutch oar, the blade of its cantilever is forward.Half leaf rotation clutch oar is at initial position, and it is all parallel with the line of centers of handle bar 17 that all change slurry 7.When striking, before half leaf rotation clutch oar enters the water surface, the operator firmly holds the afterbody of the lever 15 of pinching tension mechanism 6, utilize lever principle, the head of lever 15 drives crossbeam wire drawing 5, crossbeam 3, crank throw wire drawing 4 is up, crank throw wire drawing 4 driven rotary again starches 7 about left-hand revolution shown in Figure 1 90 degree, last backstop 10 restriction rotation slurries 7 continue rotation, all change slurry 7 by the original state that is parallel to each other, rotate to and almost be in conplanely mutually, mutually head and the tail form a big plane in overlap joint ground mutually, and this big plane is exactly the upstream face of striking, the operator brandishes arm backward, just produces enough propelling thrusts.When operator's withdraw the arm, unclamp the afterbody of the lever 15 of tension mechanism 6, combined action by torsion spring 9 and retracing spring 16, the identical angle of 7 opposite spins is starched in all rotations, return to initial position, at this moment, half leaf rotation clutch oar is even without breaking away from the water surface, because the blade 12 on the rotation slurry 7 is parallel with working direction, in water, there is not resistance to produce basically.So just realized goal of the invention of the present utility model.

Product of the present utility model, the accessory appliances in the time of can also being used as swimming can improve swimming rate.
