Active arc-shaped gear 701 just will drive transmission arc-shaped gear 706 and be rotated along connecting shaft 705 when barbell bar 6 rotates, and pass through connection
The rotation of axis 705 can drive permanent magnets 1 to be rotated, when permanent magnets 1 rotate 180 degree after, permanent magnets 1 with forever
Magnetic pole between magnetic patch 2 906 will be identical, can be by card by mutually exclusive between permanent magnets 1 and permanent magnets 2 906
Tight hook 904 provides the active force for being detached from clamping rack gear 8, and slightly drives barbell bar 6 to move up by above pushing away barbell bar 6 can to make card
Tight rack gear 8 is detached from chucking hook 904, passes through the sliding sleeve 3 of 2 outer surface pivot bush unit of fixing pipe and the appearance of sliding sleeve 3
Face, which is connect by fixed ring 4, bearing 1 with barbell bar 6, can make people make barbell bar 6 along solid when recumbency crouches and pushes away and temper chest
Determine pipe 2 and carry out up and down, passes through having an effect and barbell bar 6 is driven be vertically moved up or down up and down with human chest and arm
Achieve the purpose that exercise, permanent magnetism can be made by passing through rotation barbell bar 6 when training terminates or encounters and is short of physical strength and is difficult to push
Magnetism between block 1 and permanent magnets 2 906 is on the contrary, the principle to be attracted each other by opposite magnetic pole can be such that chucking hook 904 mentions
For contacting the active force of clamping rack gear 8, facilitates and barbell bar 6 is connected on clamping rack gear 8 and to barbell bar 6 in fixing pipe 2
Placement is fixed.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
