One mobile jib 20 also is square telescoping tube group in the present embodiment, and the right flank of mobile jib 20 is provided with positioning piece bolt 25, is used to locate the distance of the top of mobile jib 20 with respect to the bottom.The bottom of mobile jib 20 is hubbed on the pedestal 15 of bottom bar 13, by a pivot pin 21 with about be through at pedestal 15 and mobile jib 20 bottoms to pivot, make that mobile jib 20 can be along the front and back of pedestal 10 to deflection, the shaft of mobile jib 20 is then from pedestal 10 extension that upwards recedes.The leading flank of mobile jib 20 be installed be Y-axis to one first sleeve pipe 22 and be positioned at one second sleeve pipe 23 of first sleeve pipe, 22 belows.Be provided with in first sleeve pipe 22 towards about the mandrel rod 26 that extends of two outsides, mandrel rod 26 can freely be detached in first sleeve pipe 22 and be located in addition in second sleeve pipe 23.The trailing flank of mobile jib 20 with respect to first sleeve pipe, 22 higher positions be provided be Y-axis to one the 3rd sleeve pipe 24.

One back pad 30, for periphery is coated with the rectangular pad of flexible material, its back side middle position is provided with a pedestal 31.Back pad 30 is hubbed on the top of mobile jib 20 by pedestal 31, and with a pivot pin 32 with about to being located in pedestal 31 and mobile jib 20 tops, making back pad 30 can mobile jib 20 tops be axis of rotation, to rotation (shown in imaginary line among Fig. 2), then be as shown in Figure 2 state along the front and back of mobile jib 20 at ordinary times because of own wt.

One seat 40, it includes a chair cushion 41 and is located at the two secured in parallel bars 42 that chair cushion 41 bottoms have preset space length.The rear side at chair cushion 41 is protruded in the rear end of two fixed bars 42, and place respectively mobile jib 20 about two sides, be located in two fixed bars, 42 rear ends and the 3rd sleeve pipe 24 by a pivot pin 43 again, make two fixed bars 42 towards mobile jib 20 front sides, and the bottom surface is butted on the mandrel rod 26, form seat 40 and be hubbed on the mobile jib 20, be predetermined angular with mobile jib 20, chair cushion 41 then is positioned at the state of mobile jib 20 front sides.Be inserted in first or

second sleeve pipe

22,23 by mandrel rod 26, can make seat 40 on mobile jib 20, have different angles.

One spring lever 50, its bottom is hubbed on the bottom bar 13 of pedestal 10, and pivot part is positioned at mobile jib 20 rear sides, and the top then is located in the rear side of mobile jib 20 by a detachable steady pin 51, forming spring lever 50 tiltedly is located between mobile jib 20 nearly bottom positions and the pedestal 10, for mobile jib 20 provides resiliency supported.

Two elastic threads 60, respectively along front and back to be arranged on pedestal 10 about two sides, and be located on the corresponding assembly pulley 16.Two ends of each elastic threads 60 are respectively equipped with a ring body 61.One round forced section 62 selects hook in detachable mode in the ring body 61 at elastic threads 60 the place aheads or rear for the user, and two forced sections 62 are available for users to the both hands gripping or cover hangs on the biped.

Adopt the stretching, extension body exercising machine of said structure, utilize bottom bar 13 characteristic of telescopic of mobile jib 20 and pedestal 10, the user can be adjusted to the position that is fit to own build with pin hook part 17 and back pad 30 earlier, and then uses the utility model to carry out following body building:

1, as shown in Figure 4, the back is resisted against on the back pad 30, both feet hook the pin hook part 17 of pedestal 10, then utilize the pivot of back pad 30, allow health lie to layback and reach the effect of stretching, extension, with stretching, extension and the exercise that provides the user to do back, abdominal muscles.

2, as shown in Figure 5, the user is sitting on the seat 40, with the hands grips the forced section 62 that is located at two elastic threads, 60 rear ends, and elastic threads 60 is stretched act towards health front side oblique upper, so can temper shoulder muscle.

3, as shown in Figure 6, the user is sitting on the seat 40, with the hands grips the forced section 62 that is located at two elastic threads, 60 front ends, and elastic threads 60 is drawn act towards the top, so also can temper the muscle of shoulder or arm.

4, as shown in Figure 7, the user is sitting on the seat 40, and a pin is trampled on front rail 11, and another footmuff firmly is located at the forced section 62 of an elastic threads 60 front ends, and elastic threads 60 is stretched towards the top, can temper leg muscle.

5, as shown in Figure 8, the user directly tramples on the rear transverse rod 12 of pedestal 10, and two elastic threads 60 that with the hands upwards stretch can reach the muscular training function of hand, arm.

6, the user is resisted against the back on the back pad 30, both feet catch on pin hook part 17, and both hands are held the forced section 62 that is located at two elastic threads, 60 rear ends, when health utilizes the pivot of back pad 30 and swings back stretching routine, both arms can make progress or the two sides action that stretches to the left and right synchronously, temper two kinds of muscle simultaneously.

In addition, the user also can adopt health by after the mode of lying prone forward, belly is resisted against on the back pad 30, and both hands are held the pin hook part 17 of pedestal 10, to be similar to the posture of pushup, carry out the exercise motion of belly and arm muscles.

When the user does not need body-building, as shown in Figure 3, the bottom bar 13 of mobile jib 20 and pedestal 10 can be received extremely short status earlier, then the steady pin 51 of spring lever 50 is detached, it is parallel with pedestal 10 to allow spring lever 50 be folded to, and then mobile jib 20 is gone to collapsed position, detaches mandrel rod 26 at last, make seat 40 transmit the state that is parallel to mobile jib 20, can folding the utility model.

By this, the utility model can allow the user safer and comfortable when operation, and can allow the user do multiple body building, reaches the effect of all-around exercises.
