Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1, the interlock adjustment handle provided in this embodiment includes a Z-shaped handle rod 1 and a switching mechanism 3, a forward rotation one-way bearing 41 and a reverse rotation one-way bearing 42 are connected to the Z-shaped handle rod 1, and the switching mechanism 3 switches to brake an outer ring of the forward rotation one-way bearing 41 or the reverse rotation one-way bearing 42. Preferably, the switching mechanism 3 comprises two bearing fixing rings 31, a sliding brake ring 32; the two bearing fixing rings 31 are respectively fixed on the outer rings of the forward rotation one-way bearing 41 and the reverse rotation one-way bearing 42, the sliding brake ring 32 is sleeved on the Z-shaped handle rod 1, the sliding brake ring 32 can axially slide, and the sliding brake ring 32 is sleeved between the forward rotation one-way bearing 41 and the reverse rotation one-way bearing 42; the inner side wall of the sliding brake ring 32 is provided with a brake notch 333, and one side of each of the two bearing fixing rings 31 facing the sliding brake ring 32 is provided with a brake boss 311 matched with the brake notch 333. However, when only the forward rotation is required, which is defined as clockwise rotation, the toggle sliding brake ring 32 is snapped into the bearing fixing ring 31 of the forward rotation one-way bearing 41, so that the bearing fixing ring 31 cannot rotate, and thus when the rotation direction of the Z-shaped handle 1 is different from the rotation direction of the forward rotation one-way bearing 41, the braking can be performed, and the unrestrained reverse rotation one-way bearing 42 can rotate along with the Z-shaped handle 1 and is not restricted.
