Compared with background technology, what is had has the advantages that the utility model：The design is different from prior art
The mechanism of one entirety, spring and handle are only included, but spring has been divided into two parts, and by resetting between two springs
Bending spring is attached, reset bending spring bending angle and spring tightness determine we carry out bending exercise strength it is strong
Degree, adjusts more upward by the elastic rotation adjusting lever at handle tube, and we constantly rotate swivelling cover so that on adjusting rod
Rise, adjusting rod moves up in intensity block, and at this time spring can also relax, and integral reset intensity can reduce, then spring meeting
It is more loose, it is bigger at this time to reset bending spring camber, then the intensity of exercise is with regard to smaller；In turn and we constantly rotate rotation
Lid so that adjusting rod declines, and adjusting rod moves down in intensity block, and at this time spring can also collapse tightly, integral reset intensity meeting
Improve, then spring can be tighter, at this time resets bending spring camber with regard to smaller, then the intensity of exercise is bigger.

Embodiment
Below by embodiment, with reference to accompanying drawing, the technical solution of the utility model is described in further detail：
Embodiment 1, as Figure 1-3, one kind possess rotary shaft doubling and can adjust chest-developer, including left arm handle（1）And the right side
Arm handle（2）, connected between left arm handle and right arm handle by shaft machine（3）Group is attached, the left arm handle and right arm handle structure one
Cause mirror image, including overclad tubes each other（4）, handle tube（5）, spring（6）, bottom hand handle sleeve pipe（7）, overclad tubes include barrel（8）
With the egative film in insertion groove bottom of the tube chute（9）；Spring is set in handle tube, and spring all sets eave tile end to end（10）, handle tube
Afterbody sets adjuster（11）, adjuster includes set screw（12）, adjusting bracket（13）, set screw is spirally connected into adjusting bracket, adjusts
Save frame and shifting groove is set（14）, move and slide-bar be set in groove（15）, eave tile hook is on slide-bar；The handle tube head end also sets up pivoted frame
（16）, the pivoted frame is L shape, and pivoted frame and overclad tubes direction joint set bending rotating shaft A（17）, pivoted frame and shaft machine connect
One end sets oval head（18）, round end shaft core position, which is also set up, bends rotating shaft B（19）；
The shaft machine includes snail axle housing（20）, curved protective case（21）, center pulling-on piece（22）, snail axle housing lower hollow,
Match hollow part and cover the curved protective case of setting, the curved protective case bottom sets handle connecting seat（23）, handle connecting seat and bending
Rotating shaft B is attached, and easement song rotating shaft B is rotated, and handle connecting seat connects with handle tube；The center pulling-on piece is from snail axle
Shell bottom is inserted, and is screwed in therein by snail axle housing profit, and center pulling-on piece is provided with three and is triangularly arranged
Connecting screw hole（24）, match connecting screw hole cuttage grafting frame axle（25）, flexible draw cord is provided with the top of the pulling-on piece of center（26）, it is flexible
Drawstring is bundled on the spring of left arm handle and right arm handle end to end.
Central fixed shaft hole is additionally provided with center as the preferred connecting screw hole（27）, central fixed shaft hole
Inside also it is plugged with 1 frame axle.
It is less than snail axle housing diameter as the preferred center pulling-on piece length, and after both connection settings, center pulldown
From at least 2cm with a distance from the outer casing inner wall of snail axle housing.
Anti-slip rubber layer is sheathed with as preferred bending rotating shaft A, B surface.
As setting Ka Dong at the top of preferably described adjusting bracket（28）, bottom sets damping tooth（29）, adjusting bracket bottom is set
