Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of armed classroom seat of tool, including seat 1 and handrail 6, the bottom of the seat 1 are equipped with
The side of holder 2, the seat 1 is equipped with backrest 3, and the both ends of the backrest 3 are equipped with link block 4.
The one end of the link block 4 far from backrest 3 is equipped with connecting pole 5, and one end of the handrail 6 is equipped with through-hole 7, described logical
Hole 7 is internally provided with push-pull rod 8, and the one end of the push-pull rod 8 far from block 9 is arc, and is equipped with striped, facilitates students
Press, through-hole 7 is stretched out at the both ends of the push-pull rod 8, and the push-pull rod 8 is equipped with block 9 close to one end of backrest 3, described
Side of the block 9 far from push-pull rod 8 is equipped with the first spring 10, and the inner wall of the handrail 6 is equipped with spacer block 12, first spring 10
One end far from block 9 is connect with spacer block 12, and the block 9 is equipped with slide bar 11, connecting pole 5 close to the middle place of 12 side of spacer block
In the lower section of slide bar 11, block 9 is moved by the elastic band moving slide-bar 11 of the first spring 10, and the slide bar 11 is far from block 9
One end passes through spacer block 12.
The surface of the slide bar 11 is equipped with supporting block 13, and bottom of the supporting block 13 far from 11 one end of slide bar is equipped with stop block
14, the one end of the connecting pole 5 far from link block 4 passes through handrail 6, and is rotatablely connected with the inner wall of handrail 6, the connecting pole
The surface of 5 sides is equipped with the groove 15 to match with stop block 14, and the spigot of the groove 15 is arc, is conducive to inserting for stop block 14
Enter, the center of the groove 15 and stop block 14 is in the same horizontal line.
Inner wall of the handrail 6 far from 7 side of through-hole is equipped with card slot 16, and the card slot 16 is internally provided with baffle 17, institute
It states the one end of slide bar 11 far from spacer block 12 to connect with the surface of baffle 17, the surface of the card slot 16 is equipped with limiting plate 18.
