[0002] In the existing technology, the valve bottom cup assembly of the gas pressure reducing valve is an important main body of the gas pressure reducing valve. The valve bottom cup assembly includes a valve bottom cup 400, a handwheel, a QCC part (or called a flow-through mounting part), and a rubber gasket, all of which are installed on the valve bottom cup 400. Among them, there are two types of valve bottom cups 400 on the market (named as the first valve bottom cup and the second valve bottom cup respectively): Figure 6 and Figure 7 , the back side of the cup body 430 of the first valve bottom cup is provided with an I-shaped tube portion, and the two ends of the I-shaped tube portion are respectively an inlet pipe 410 and an outlet pipe 420; Figure 8 and Figure 9 An L-shaped tube portion is provided on the back side of the cup body 430 of the second valve bottom cup, the short end of the L-shaped tube portion is the air inlet pipe 410, and the long end is the air outlet pipe 420.

[0003] In this regard, in order to automatically assemble and produce two valve bottom cup assemblies with different valve bottom cups 400, some manufacturers have designed two jigs that can respectively hold the first valve bottom cup and the second valve bottom cup, so that the two jigs can be switchably installed on the assembly equipment, so that the assembly equipment can produce the corresponding valve bottom cup assemblies. However, the applicant found in actual production activities that: 1. After the jig on the assembly equipment is switched, the production personnel still need to readjust the machine, and the readjustment work will affect the overall production cycle; 2. The work of switching the jig on the assembly equipment is very cumbersome, and the work of switching the jig will also affect the overall production cycle. Utility Model Content
