Pressure ring convenient to disassemble

According to the pressure ring convenient to disassemble, a pressure ring structure convenient to disassemble is arranged, and a pressure ring body is extruded, limited and fixed in a limiting and fixing structure at the inner side end of a pressure ring placing hole through a screw joint type fixing structure, so that the mounting stability of the pressure ring body is ensured; and then the middle of the outer side end of the pressure ring body is extruded through the screw joint type extrusion positioning structure, the mounting stability of the pressure ring body is further improved, the screw joint type fixing structure is screwed down when dismounting is needed, dismounting is convenient, dismounting or mounting can be conveniently conducted, and the stability of the pressure ring body after mounting can be guaranteed. 本实用新型公开一种便于拆卸压力环，通过设置有便拆卸式压力环结构，通过螺接式固定结构将压力环本体挤压限位固定在压力环放置孔内侧端的限位固定结构内，保证压力环本体安装稳定性，再通过螺接式挤压定位结构挤压压力环本体外侧端中部，进一步提高压力环本体安装稳定性，需要拆卸时，螺下螺接式固定结构即可，拆卸方便，能够方便进行拆卸或安装，并能保证压力环本体安装后稳定性。
