A fixing assembly is installed between the chair and the table. The fixing assembly includes a track. A first locking block is fixedly connected to one side of the track near the rear. A second locking block is inserted through the upper end of the first locking block. One side of the second locking block is fixedly connected to the chair. A mounting block is movably connected to the inner side of the track. A mounting cavity is formed inside the mounting block, and a fixing block is movably installed within the mounting cavity. Several locking teeth are provided on the other side of the fixing block near its upper and lower ends. Several tooth grooves are formed in the track near the ends of the locking teeth. A threaded rod is threadedly connected to the center of the other side of the mounting block. One end of the threaded rod is rotatably connected to the fixing block. The other side of the mounting block is fixedly connected to the table. The threaded rod passes through the other side of the table, and a knob is fixedly connected to the other end of the threaded rod.

[0007] Preferably, the upper and lower ends of the inner side of the track are fixedly connected with locking strips, and the upper and lower ends of the mounting block are provided with mounting grooves, which are used in conjunction with the locking strips.

[0008] Preferably, a fixed sleeve is movably fitted on the outer side of the track, and the opening of the fixed sleeve is fixedly connected to the table.

[0009] Preferably, mounting grooves are provided through the upper and lower ends of the mounting block and at the front and rear ends, and second silent rollers are installed at the upper and lower ends of the mounting grooves respectively.

[0010] In summary, the present application includes the following beneficial technical effects:

[0011] 1. The chair is adjusted in position along the direction of the track, the smoothness and silence of the movement are improved by the first silent roller and the second silent roller, the chair is disassembled and installed conveniently by the second clamping block and the first clamping block, the track is limited by the mounting cavity, the fixed block, the clamping tooth, the threaded rod, the knob and the tooth groove, and the position of the chair is limited, so that the noise of the chair during the position adjustment is reduced, the smoothness of the chair position adjustment is improved, and the noise generated by the chair movement does not affect the classroom order and the concentration of students.
