The invention discloses a bearing supporting structure of a pinion shaft, and particularly relates to the technical field of supporting mechanisms. The bearing supporting structure comprises balls, a wheel disc, pulleys and sliding chutes, the balls are embedded in an inner cavity of the wheel disc, flat teeth are movably attached to the surfaces of the balls, the bottoms of the flat teeth are movably sleeved with convex teeth, and the bottom surfaces of the convex teeth are fixedly connected with base plates; and sound absorption plates are detachably installed on the bottom faces of the base plates, bottom plates are movably connected to the bottom faces of the sound absorption plates, and sliding bases are fixedly installed on the bottom faces of the bottom plates. According to the bearing supporting structure, a telescopic rod is arranged, a rotating shaft is movably connected to the telescopic rod, the rotating shaft can be fixed or loosened at any time, the whole telescopic rod is expanded through supporting force during use so as to bear a gear shaft bearing, conversely, the telescopic rod can be shrunk only by loosening the rotating shaft and slightly pushing the telescopic rod with force after use, the telescopic rod is small in size after being shrunk, space is not occupied, and storage is convenient.

    本发明公开了一种小齿轮轴的轴承支撑结构,具体涉及支撑机构技术领域,包括滚珠、轮盘、滑轮、滑槽,轮盘的内腔镶嵌安装有滚珠,滚珠的表面活动贴合有平齿,平齿的底部活动套接有凸齿,凸齿的底面固定连接有垫板,垫板的底面可拆卸安装有吸声板,吸声板的底面活动连接有底板,底板的底面固定安装有滑座。本发明通过设置收缩杆,收缩杆上活动连接有旋转轴,旋转轴可以随时固定或松开,使用时利用支撑力撑开整个收缩杆,从而承载齿轮轴轴承,反之,使用完毕后只需要松开旋转轴,稍做力往里轻推就可以收缩,收缩完毕后体积小,不但不占空间,而且方便收纳。
