The shift shaft 210 is transmitted to the shift connecting shaft 110 through the cooperation of the gas valve rod (not shown in the figure), the power-assisting cylinder push rod (not shown in the figure), the power-assisting gas valve dial head 230 and the power-assisting shift dial head 120. The mounting groove 220 is a through-groove structure. An end cover 280 is provided outside the mounting groove 220 and at the other side relative to the power-assisting gas valve dial head 230 and the power-assisting shift dial head 120. A second end cover 280 is provided between the end cover 280 and the connecting seat 200. The sealing gasket 281 and the mounting groove 220 are set as through grooves to make assembly easier. The addition of the second sealing gasket 281 allows the end cover 280 to seal with the connecting seat 200, thereby increasing the structural stability. The air valve stem and the power-assisting cylinder push rod are common parts of the cylinder device, and their installation and operation will not be described in detail. The technical problem to be solved by this application is to improve the connecting seat 200, and to set a mounting groove 220 on one side of the connecting seat 200 to connect the power-assisting device, so as to achieve the purpose of saving effort by installing the power-assisting device at the mounting groove 220 and connecting the power-assisting air valve dial head 230 and the power-assisting shift dial head 120.
