When using this product to carry out arm exercise, place this product base on the horizontal plane, both hands grip two handle sleeve pipes respectively, outside both sides pulling handle sleeve pipe to outside extreme position, rotate the interior body of rod immediately for the interior body of rod enters into the holding tank, and the handle sleeve pipe enters into in the holding tank under the drive of the interior body of rod this moment. And the handle sleeve is pressed inwards forcibly, so that the insertion column is inserted into the second insertion hole, and the handle sleeve and the hand wheel are fixed relatively. The in-process of second spliced eye is inserted to the grafting post, and the handle sleeve pipe will offset and make spacing post move to the inboard with spacing post, and then makes spacing latch move to the inboard, spacing latch no longer with interior ring gear joint, the second spring compression simultaneously, the hand wheel can rotate the mounting disc relatively. The interior pole body rotates the in-process for sector gear rotates, and two sector gears are connected with the gear drive that links respectively, and sector gear rotates and drives the gear rotation that links, and the gear rotation that links drives another sector gear and rotates, thereby makes two interior pole body synchronous motion, and the operation is simple and convenient more.

The hand wheel pawl and the ratchet form a ratchet pawl mechanism in one-way transmission, when the hand wheel stops rotating, the counterweight wheel still rotates under the action of inertia, and the hand wheel cannot rotate due to the rotation of the counterweight wheel, so that the situation that the counterweight wheel drives the handle sleeve to move can be avoided, and joint damage of a user is prevented.

After the exercise is completed, the two handle sleeves are gripped by the two hands and pulled outwards, so that the inserting column leaves the second inserting hole, the limiting column moves outwards under the elastic action of the second spring, and the limiting latch is connected with the inner ring gear in a clamped mode. If the limiting latch is not just opposite to the teeth of the inner ring gear, the hand wheel can be rotated, so that the limiting latch is clamped with the next adjacent tooth, and the hand wheel is relatively fixed with the mounting disc. Pulling handle sleeve pipe to outside extreme position, the outside motion of handle sleeve pipe will make connecting pin pulling spread groove, and then makes interior pole body rotate to the outside and leave the holding tank, until handle sleeve pipe and interior pole body collineation and relative level. Then, the handle sleeve is pushed inwards to the limit position of the inner side, so that the inner rod body is inserted into the handle sleeve, meanwhile, the insertion column is inserted into the first insertion hole, and the handle sleeve and the hand wheel are fixed relatively.
