[0010] In a preferred example, the utility model can be further configured as follows: a guide rod is movably inserted into the top end of the T-shaped seat, and the spring is sleeved on the outside of the guide rod.

[0011] In a preferred example, the utility model can be further configured as follows: a plurality of rubber pads are installed at the bottom end of the support frame, and the thickness of the rubber pads is set to 4 cm.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] 1. In the utility model, when the user leans against the backrest, the carbon fiber plate and the sliding sleeve cooperate to press against the backrest and relieve the pressure on the backrest. Then, the greater the pressure the user applies to the backrest, the sliding sleeve will rise along the reinforcing plate, which provides the backrest with the conditions for bending, giving the user a better experience and reducing the probability of deformation or breakage of the backrest.

[0014] 2. In the utility model, the bottom end of the carbon fiber plate drops, which transmits force to the clamping sleeve, and then the clamping sleeve presses the spring to deform, and the spring buffers the force, while reducing the load on the backrest to a certain extent, further reducing the probability of deformation or breakage of the backrest.
