Chest expander is a kind of instrument being suitable for national physical training exercise.It is advantageous in that using chest expander exercise：The upper arm two
Flesh is the muscle of flesh head there are two one piece, and main function is to crook one's arm.When crooking one's arm, other one piece of muscle has equally also been used,
Brachialis.And only in the movement lifted on doing some forearms, such as high-order curved act of chest expander or trans- high-order chest expander toy, brachialis
Just can fully it be taken exercise.In addition, the major muscles brachioradialis on forearm top, also plays many effects in bent arm action, and
Brachioradialis can be made to be strengthened by the act of chest expander lateral bending.
Chest expander generally comprises high-quality lever and high intensity tension spring, is 150 centimetres including handle, both ends decreased food
Totally 30 centimetres, tension spring grows 120 centimetres, and maximum expansion degree is 120 centimetres, can meet the body-building demand of different height crowds.
With the development of the times, chest expander also begins to away fashion road.Clumsy chest expander can only be suitble to use in household,
Since volume is larger and again, not portable or Portability is very poor, thus can not meet the requirement that people take exercise whenever and wherever possible.
Meanwhile the elastic body normal length of existing chest expander is fixed nonadjustable, it is difficult to meet the crowd that dissimilar arm exhibition needs.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of fitness and body-building chest expander.
The utility model is achieved through the following technical solutions：
The utility model provides a kind of fitness and body-building chest expander, which includes：The elastic force of strip
Body, and two draw ring components at the elastic body both ends are separately positioned on, each draw ring component includes tension ring and connection
Shaft, the tension ring are connect by the connection shaft with the elastic body, and the tension ring is hatch frame, opening portion
Vertical both sides are correspondingly arranged on through-hole, and the both ends of the connection shaft are each passed through two through-holes, and in the connection shaft
Two ends a rotating handle is respectively set, two rotating handles are located at the both sides outside the tension ring, can pass through the rotation
Handle rotates the connection shaft, and two ends of the tension ring opening portion transverse direction are respectively arranged with the spiral shell being connected to the through-hole
Pit is provided with locking nut in the threaded hole, can pass through and connect shaft rotation described in the locking nut locking.
Preferably, the elastic body is strength elastic band or elastic telescopic hose.
Preferably, the elastic body and the connection shaft integrally connected.
Preferably, the one end of the tension ring far from its opening portion is the comfortable handle for meeting ergonomics.
Preferably, the rotating handle and the connection shaft integrally connected.
The utility model has the beneficial effects that：It is simple in structure, it can accomplish partially and fully to wind elastic body, be applicable in difference
Be trained using crowd, and it is easy to carry.
