Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

As shown in Fig. 1, Fig. 2 and Fig. 3: the present invention comprises backboard 1, braces 2, backboard rotating shaft 3, lever arm 4, connecting rod 5, connecting rod spring seat 6, connecting rod spring 7, lever arm spring seat 8. Lever lock pin 9, lever arm spring 10, handle shaft 11, handle rotation link 12 and handle 13, two straps 2 are arranged on one side of the backboard 1, and the backboard 1 The two ends of the other side are respectively provided with a said backboard rotating shaft 3, and the two said backboard rotating shafts 3 are respectively connected to the fulcrum rotating shafts of the two said lever arms 4, and the two said lever arms 4 are respectively connected to one of said connecting shafts. One end of the rod 5 is rotationally connected, the connecting rod spring seat 6 is set on the connecting rod 5, two lever arm spring seats 8 are arranged on the lever arm 4, and the connecting rod spring seat 6 and the lever The link spring 7 is connected between the arm spring seats 8, the lever arm spring 10 is connected between the lever arm spring seats 8 between the two lever arms 4, and the lever arm spring 10 is connected between the two lever arms 4 through the The lever lock pin 9 is detachably connected, and the ends of the two connecting rods 5 are all connected to the handle 13 through a handle rotating shaft 11 and a handle rotating link 12 .

Further, the connecting rod spring 7 is multiple or at least one tension spring with different strengths. The lever arm spring 10 is a plurality of or at least one tension spring with different strengths.

The working principle of the present invention is as follows:

During exercise, the strap is carried on the shoulders, and the handle 13 is held with both hands. After connecting and dismantling the lever lock pin 9, the connecting rod spring 7 and the lever arm spring 10 act at the same time, and the rotation angle becomes larger, which can exercise the arms and chest muscles simultaneously.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments.
