Low-cost micro rod clamping structure

The utility model relates to the technical field of workpiece clamping, in particular to a low-cost micro bar clamping structure which is particularly suitable for clamping micro bars or micro pipes with the diameter smaller than 0.5 mm. The low-cost micro bar clamping structure comprises an elastic collet chuck, a central round hole is formed in the elastic collet chuck, and a plug gauge assembly capable of being used for clamping the bars or the pipes with the diameter smaller than 0.5 mm is installed in the central round hole. Due to the adoption of the structural arrangement, the plug gauge assembly is additionally arranged in the central circular hole in the elastic collet chuck, so that the elastic collet chuck can be used for clamping a bar or a pipe with the diameter smaller than 0.5 mm, and is simple in structure, low in manufacturing cost and short in manufacturing time. 本实用新型涉及工件夹持技术领域，特指一种低成本的微细棒夹持结构，尤其适用于直径小于0.5mm的微细棒料或微细管材的夹持，包括弹性筒夹，弹性筒夹内设有中心圆孔，中心圆孔内安装有可用于夹持直径小于0.5mm的棒料或管材的塞规组件。本实用新型采用这样的结构设置，通过
