Embodiment

The utility model is further described with reference to Figure of description.

Embodiment 1

As Figure 1-3, a kind of physical fitness stretcher of the present embodiment, including the first stretch rod 1, the second stretch rod 2, two Individual extension spring 4 and two handles 3；

First stretch rod 1 is provided centrally with through hole；Fixed block 6 is provided with the through hole；The fixed block 6 is by institute State the first stretchable holes 5 and adjustment hole 7 that through hole is cut into two unidirectional outlets；The inner surface setting of adjustment hole 7 has screw thread；Wherein One end of one extension spring 4 is fixed on fixed block 6, and the other end is consolidated through the stretchable holes 5 with one of them described handle 3 Fixed connection；

Second stretch rod 2 includes the second stretchable holes 9 and adjusting rod 8 of integrally casting；Second stretchable holes 9 are blind Hole；Another described one end of extension spring 3 is fixedly connected on the bottom of second stretchable holes 9, and the other end is stretched through described second Hole 9 is fixedly connected with handle another described 3；The outer surface of adjusting rod 8 is provided with screw thread；

The adjustment hole 7 is connected with the screw thread of adjusting rod 8；

Two front ends of handle 3 are provided with thread segment, and first stretchable holes 5 and second stretchable holes 9 export interior Wall is provided with internal thread segment；The thread segment of two handles 3 and first stretchable holes 5 and second stretchable holes 9 it is interior Thread segment is adapted；By the handle 3 and first stretchable holes 5 and the spiral shell of the second stretchable holes 9 when without using stretcher Line is rotatably connected；The handle 3 is not connected to first stretchable holes 5 and second stretchable holes 9 when using stretcher；

First stretch rod 1 is made up with second stretch rod 2 of carbon fibre composite, and lightweight rigidity is big, fits Close person taking exercise to hold for a long time, the outer wall of first stretch rod 1 and second stretch rod 2 is respectively arranged with hook, it is convenient Place；Bandage is also fixedly connected with the handle 3；Bandage is set to prevent that the loose stretcher of hand flies out during exercise.

It is when person taking exercise is taken exercise using stretcher, first stretch rod 1 and second stretch rod 2 is tight by screw thread It is solidly connected, pull handle 3 carries out arm strength stretching after connection；

When person taking exercise feels that pulling force is small using stretcher, by between first stretch rod 1 and second stretch rod 2 Distance by threaded adjusting, reduce the distance between first stretch rod 1 and described second stretch rod 2, person taking exercise exists When being taken exercise using the stretcher after adjustment, when moving position when not adjusting to, pulling force used becomes big；

When person taking exercise feels that pulling force is big using stretcher, by between first stretch rod 1 and second stretch rod 2 Distance by threaded adjusting, make the increase of the distance between first stretch rod 1 and described second stretch rod 2, person taking exercise exists When being taken exercise using the stretcher after adjustment, when moving position when not adjusting to, pulling force used diminishes；

The handle 3 can be coordinated by the internal thread segment of the end of thread and the stretchable holes 9 of the first stretchable holes 5 and second simultaneously Connection, facilitates person taking exercise to carry and put, and is also prevented from having foreign matter to enter the stretchable holes of the first stretchable holes 5 and second when not in use 9；Person taking exercise use stretcher when, by two handles 3 respectively with first stretch rod 5 and the edge of the second stretchable holes 9 Screw thread rotation is separated, then using stretcher.

The present embodiment is simple in construction easy to operate, is person taking exercise provider while the pulling force size of stretcher can also be adjusted Just.

Embodiment 2

As shown in figure 4, based on embodiment 1, the present embodiment also includes the first pedal and the second pedal；First pin Pedal includes the first pedal body 10 and the screw rod 11 being fixedly connected vertical with first pedal body 10；The screw rod 11 with The adjustment hole 7 of first stretch rod 1 is adapted；Second pedal includes the second pedal body 12 and stepped on described second The barrel 13 that plate body 12 is vertically fixedly connected；The barrel 13 is adapted with the adjusting rod 8 of second stretch rod 2.

When first stretch rod 1 and second stretch rod 2 are used separately, by the regulation of first stretch rod 1 The screw thread of screw rod 11 of hole 7 and first pedal, which coordinates, to be fastenedly connected；The adjusting rod 8 of second stretch rod 2 and described the The screw thread of barrel 13 of two pedals is connected；After connection is finished, the first pedal and the second pedal, hand-held handle 3 are slammed Squatting up and arm up-down stretch is carried out to move simultaneously, can take exercise arm strength can also leg exercising bending expansion service.

The present embodiment is simple in construction easy to operate, not only allows person taking exercise to carry out arm up-down stretch motion, moreover it is possible to enter simultaneously Row squatting up is moved, and is added the feature of stretcher, person taking exercise is obtained more exercising patterns.
