A chair elbow capable of rotating with double shaft is disclosed. Two bearings are disposed on a mount board fixed on a chair. Each of the bearings connects one end of each of two rotating plates, while the other ends thereof are pivotally connected in a linear slot of a seat plate used for securing an armrest. The length of the slot is longer than the distance between the two bearings, and the latter is longer than the length of the rotating plates. Thus, the armrest on the seat plate can rotate against the mount board with 360 degrees and move forward and backward.

1.

1. A rotary elbow of chair comprising: a mount board;two bearings, each having a first pivot seat and a second pivot seat axially aligning with each other, and the two first pivot seats being separately fixed at two ends of the mount board;two rotating plates, one end of each of which fixedly connects one of the second pivot seats; anda seat board having a linear slot, two pivot shafts penetrating the slot to pivotally connect the other end of each of the rotating plates;thereby the rotating plates can rotate on the mount board about the bearings. 2. The rotary elbow of chair of claim 1, wherein the mount board is provided with two mounting holes for separately being embedded by the first pivot seats of the bearings, and each the rotating plate is provided with a connecting hole for being embedded one of the second pivot seats. 3. The rotary elbow of chair of claim 1, further comprising two fastening rods separately penetrating the rotating plates, the bearings and mount board. 4. The rotary elbow of chair of claim 1, wherein a length of each the rotating plate is shorter than a distance of the two bearings and a length of the slot is longer than the distance of the two bearings. 5. The rotary elbow of chair of claim 1, wherein the other end of each the rotating plate is provided with a pivot hole, and two pivot shafts separately penetrate the slot and pivot holes to form a pivotal connection, thereby the seat board can linearly move forward and backward under orientation of the pivot shafts and slot. 6. The rotary elbow of chair of claim 3, wherein at least one of the bearings comprises: a round seat, provided with a plurality of rolling balls in an annular arrangement with an identical pitch, wherein the round seat has a first shaft base protrudent from a center thereof and a first shaft hole is disposed in the first shaft base;a flexible depressor, being a round disk on the round seat, having a through hole at a center thereof, and being provided with circular holes corresponding to the rolling balls; anda cap covering the round seat to accommodate the flexible depressor therein, wherein the cap has a second shaft base at a center thereof for penetrating into the through hole to secure the flexible depressor, the second shaft base is provided with a second shaft hole therein and the first shaft hole, the through hole and the second shaft hole directly communicate with each other;wherein the flexible depressor presses the round seat, a positioned status can not be formed until the circular holes are embedded by the rolling balls, when the cap is forced to rotate with the flexible depressor against the round seat, the rolling balls diverge from the circular holes to rotate and the flexible depressor is deformed by being leaned by the rolling balls, and when the rolling balls move to a position of the circular holes again, they will be automatically embedded into the circular holes to make another positioned status by means of pressure from the flexible depressor. 7. The rotary elbow of claim 6, wherein the circular holes are the same as the rolling balls or an integer multiple of the rolling balls in number. 8. The rotary elbow of claim 6, wherein an outline of the second shaft base is a many-sided body. 9. The rotary elbow of claim 8, wherein the second shaft base extends from the cap inwards and outwards, and an inward part of the second shaft base penetrates into the through hole. 10. The rotary elbow of claim 9, further comprising bending edges extending from margins of the through hole of the flexible depressor for leaning against the cap.
