[0002] Chinese patent document CN222229709U discloses a ball valve that can be installed quickly, including: a ball valve body, a connecting assembly, and a fixing assembly. A valve seat is integrally formed on the upper surface of the ball valve body, and a switch is installed on the upper surface of the valve seat. A connecting pipe is integrally formed on the front and rear surfaces of the ball valve body. Compared with the prior art, this utility model has the following advantages: By setting the connecting assembly, quick installation can be achieved during use through the cooperation of connecting flange one and connecting flange two, as well as the use of the fixing assembly, thus improving installation efficiency. At the same time, the design of the annular protrusion and annular groove increases the stability and sealing of the connection. By setting the fixing assembly, the ball valve and the connecting assembly can be quickly installed through the combination of the fixing assembly and connecting flange one and connecting flange two. At the same time, the fixing rod inside the fixing assembly passes through the fixing hole, through hole one, and through hole two, which helps to ensure the firmness of the ball valve connection.

[0003] However, in the above-mentioned solution, the top of the valve stem of the ball valve that can be installed quickly is usually fixed with a handle for controlling the opening and closing of the ball valve by tightening a nut. After long-term use, the handle of the ball valve will be damaged and broken and needs to be replaced in time. The replacement of the handle requires the use of auxiliary tools to loosen and tighten the nut, which is time-consuming and laborious, affecting the installation efficiency of the ball valve handle. Improvement and optimization are needed. Utility Model Content
