Inserting rod type quick connection device

An inserting rod type quick connection device, comprising:

• an upper sleeve with an opening at one end and internally provided with an inserting rod piece extending out of the opening, and
• a lower sleeve with an opening at one end, and the end with the opening of the lower sleeve is provided with a detachable extrusion sleeve provided with a plurality of extrusion gaskets,
• wherein the plurality of extrusion gaskets are fitted and connected to form a hollow conical cylinder with an outer conical surface, an inner conical surface, an upper end surface and a lower end surface, wherein the outer conical surface is fitted with an inner wall of the extrusion sleeve, the outer conical surface of the conical cylinder is provided with a spiral groove, the spiral groove is sleeved with a conical spring connected to the plurality of extrusion gaskets, and an outer diameter and inner diameter of the conical cylinder are gradually decreased from the lower end surface to the upper end surface;
• and
• the inserting rod piece is integrally formed and comprises an inserting rod and a fixing portion detachably connected with an inner wall of the upper sleeve, wherein a root portion of the inserting rod is connected with the fixing portion and a head portion of the inserting rod extends out of the opening of the upper sleeve, wherein the inserting rod is conical and a taper of the inserting rod is the same as that of the inner conical surface of the conical cylinder;
• and when the connection is completed, the head portion of the inserting rod passes through the conical cylinder and inner surfaces of the extrusion gaskets are fitted with a surface of the inserting rod.
