[0029] The lower stopper 7 is provided, when one end of the arm strength device is accidentally released, the arm strength device straightens fast, the winding disc 2 and the flying disc 3 rotate at a high speed, the upper stopper 4 on the flying disc 3 is clamped into the ratchet groove 601, the connecting part of the lower stopper 7 is pulled to the center of the flying disc 3 through the connecting rod 8, the lower stopper 7 is clamped into the ratchet groove 601 at the same time, and the upper stopper 4 and the lower stopper 7 clamped into the ratchet groove 601 at the same time increase the braking performance of the flying disc 3, and are suitable for the protection of the arm strength device with large force.
[0030] The winding disc 2 is wound with two wires outside, one end of one wire is connected with one side of the transverse of the external arm strength device, the other end of the other wire is connected with the other side of the transverse of the external arm strength device, the support 1 is provided with a first side rod 9 on one side of the transverse, the support 1 is provided with a second side rod 10 on the other side of the transverse, the first side rod 9 is provided with a first perforation 901 for one wire to pass through, and the second side rod 10 is provided with a second perforation 101 for the other wire to pass through, which is beneficial to guide and pull out the wire outside the winding disc 2.

The connecting piece can prevent the wire from contacting the fingers when the arm force device is not compressed during use. Since the blocking column is provided on the upper and lower ends of the rotating piece, the angle between the rotating piece and the second cylinder is prevented from becoming small, thereby avoiding the disadvantage that the wire cuts the hand during use. The rotating piece is preferably U-shaped, and can be turned by 180 degrees, while the second cylinder can be rotated by 360 degrees. Therefore, the angle does not need to be fixed during use, and the user can use it conveniently.

[0032] Further referring to Figures 1 to 6 Embodiment two discloses an arm force device centrifugal protection device, which is different from embodiment one in that the recycling piece 5 is a first attracting object, and the upper stop piece 4 can be provided with a second attracting object on the side close to the first attracting object for cooperation with the first attracting object. The second attracting object is not shown, and the second attracting object can also not be provided. When the first attracting object is a magnet, the side close to the first attracting object of the upper stop piece 4 or the whole upper stop piece 4 is made of iron material, and the upper stop piece 4 can be attracted to the first attracting object.
[0033] When the other side of the upper stop piece 4 is provided with a second attracting object, the first attracting object can be a magnet which is attracted to the second attracting object, or can be an iron material, so that the upper stop piece 4 can be attracted to the recycling piece 5 when the side of the upper stop piece 4 is close to the recycling piece 5.
[0034] When the arm force device is compressed, the winding disc 2 is driven by the spring to do the winding and unwinding motion, and the maximum speed or force of the spring winding is less than the magnetic force of the recycling piece 5, so as to prevent the upper stop piece 4 from being clamped into the ratchet groove 601 to generate braking during the contraction motion.

When the arm force device is compressed, the upper stop piece 4 returns to the original state under the influence of gravity, and the side of the upper stop piece 4 is cooperated with the first attracting object.
[0036] The first attracting object and / or the second attracting object is a magnetic object. When the first attracting object is a magnetic object, the other cooperating second attracting object can also be a magnetic object or an iron material which is cooperated with the magnetic object.
[0037] The winding disc is combined with a spring, the spring plays a role of winding and unwinding, when the reverse force of winding is too large, one side of the upper stopper is separated from the magnetic force of the recycling part 5 under the action of centrifugal force, the upper stopper is clamped into the ratchet groove 601 of the ratchet part 6 to complete the braking, when the compression movement is performed, the pawl is released from the braking under the action of gravity to restore the normal function.
[0038] The counterweight a is arranged on the side of the upper stopper 4 away from the recycling part 5, when the compression movement is performed, the side of the upper stopper 4 is more easily lowered under the action of the counterweight, and the winding disc can be inserted into the ratchet groove 601 at a higher speed by selecting the counterweight with different weights.
