A power-assisted shifting dial head 120 is provided for cooperating with the power-assisted device and linked with the shift connecting shaft 110. The power-assisted air valve dial head 230 and the power-assisted shifting dial head 120 are linked and cooperated with each other. The shifting shaft 210 is transmitted to the shift connecting shaft 110 in sequence through the power-assisted air valve dial head 230, the power-assisted device and the power-assisted shifting dial head 120. The shift connecting shaft 110 is connected to the small shift cover of the gearbox (not shown in the figure), and the shifting shaft 210 is used to connect the shift rocker arm (not shown in the figure). The connecting plate 100 and the connecting seat 200 can be fixedly assembled by bolting.

The shift shaft 210 and the power-assisting air valve shift head 230 are linked by inserting the driving pin 211 into the first guide groove 231. A retaining ring 213 for assembling the driving pin 211 is provided at the notch of the first guide groove 231 to prevent the driving pin 211 from being separated from the first guide groove 231. The power-assisting air valve shift head is linked with the rotation of the shift shaft 210 through the cooperation between the first guide groove 231 and the driving pin 211.

[0029] The power-assisted air valve head 230 is provided with a transmission pin 232 for linkage with the power-assisted shift head 120, and the power-assisted shift head 120 is provided with a second guide groove 121 that matches the transmission pin 232.

The shift shaft 210 is transmitted to the shift connecting shaft 110 through the gas valve rod (not shown in the figure), the boost cylinder push rod (not shown in the figure), the boost gas valve head 230 and the boost shift 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 boost gas valve head 230 and the boost shift head 120. A second 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 and the connecting seat 200 to play a sealing role, thereby increasing the structural stability. The air valve stem and the power-assisted cylinder push rod are common parts of the cylinder device, and their installation and operation are not described in detail. The technical problem to be solved in this application is to improve the connecting seat 200. A mounting groove 220 that can be connected to the power-assisted device is set on one side of the connecting seat 200, so that the power-assisted device can be installed at the mounting groove 220 to cooperate with the power-assisted air valve dial head 230 and the power-assisted shift dial head 120 to achieve the purpose of saving effort.
