[0036] The principle and process of adjusting and fixing the angle of the backrest (i.e., chair back) of the utility model are as follows:

[0037] The utility model drives the rod 5 to clamp the corresponding hole position of the rotatable backrest connector 1 through the handle 62 to fix the different angles of the backrest. Because of the clamping position, it is not easy to slide. Specifically, in the initial state, one end of the rod 5 is inserted into a certain through hole 10, and then the operator pulls the handle 62 to drive the connector 61 through the angle locking link 6, so that the baffle 9 drives the rod 5 to be withdrawn from the through hole 10. After the operator adjusts the rotation angle of the backrest connector 1 through the backrest, the operator manually resets the angle locking link 6 to insert the rod 5 into another through hole 10 (or relies on the elastic force of the second spring 51 to insert the rod 5 into another through hole 10), thereby completing the angle fixing of the backrest. Preferably, the number of the through holes 10 is 4, that is, the angle adjustment lock of the utility model has four gears that can be locked and fixed at different angles.

[0038] The principle and process of the utility model for adjusting the seat height are as follows:

[0039] The lifting handle 71 elastically controls the gas rod inserted into the gas rod mounting hole 42 through the spring member 72 to adjust the seat cushion height. Specifically, the operator moves the lifting handle 71 up and down to make the second straight portion 75 press against the head of the gas rod, so that the gas rod pops out; the operator presses the lifting handle 71 again and sits on the seat and pushes down, so that the gas rod can retract.

[0040] The utility model also provides an e-sports chair, which adopts the seat angle-adjustable tray.
