[0011] A steel ball strip connected with steel balls is connected to the middle rail;

[0012] The blocking block is fixedly connected to the outer rail;

[0013] The inner rail pulls the middle rail to slide, the middle rail pulls the steel ball strip to slide in the outer rail, the steel ball strip slides to the maximum range, and the steel ball strip abuts against the blocking block.

[0014] Further, a clamping groove is formed in the outer rail, the clamping groove is matched with the clamping block, and when the clamping block is installed in the clamping groove, the limiting block abuts against the outer rail.

[0015] Further, the middle rail is connected with a ball holder, and the ball holder is connected with the inner rail in sliding mode.

[0016] Compared with the prior art, the buffer assembly and the three-section slide rail have the following beneficial effects:

[0017] The parts not involved in the device are the same as or can be realized by the prior art, the blocking block fixedly connected to the outer rail can effectively resist the steel ball strip when the middle rail slides, can effectively prevent the blocking block from falling off the outer rail, the application does not need to bend the hole face of the hole in the outer rail to block the blocking block, and the smoothness in the sliding process of the slide rail is ensured; meanwhile, the rubber blocking block can effectively buffer the steel ball strip in movement, reduce the possibility of the middle rail impacting the outer rail, and prolong the service life of the slide rail.
