[0008] Preferably, the connecting assembly includes: a connecting piece, whose front end is sleeved on the electric cylinder shaft and whose rear end is connected to the cylinder shaft of the booster cylinder assembly; and an adjusting piece, which is sleeved on the electric cylinder shaft and whose end face abuts against one side of the connecting piece, and is used to push the connecting piece to move on the electric cylinder shaft to adjust the extension length of the electric cylinder shaft.

[0009] Preferably, the adjusting member is configured as a nut which is threadedly connected to the electric cylinder shaft.

[0010] Preferably, the front end of the oil cylinder shaft has a clamping block, the front end of the clamping block is connected to the connecting piece, and the rear end abuts against the front end surface of the reset push plate.

[0011] Preferably, an electric cylinder base is provided on the main base for fixing the booster electric cylinder assembly.

[0012] Compared with the prior art, the technical solution has the following outstanding and beneficial technical effects:

[0013] 1. The booster electric cylinder assembly designed in this technical solution serves as a driving part of the booster oil cylinder assembly, which can better control the stroke of the booster oil cylinder assembly, and the stroke of the booster oil cylinder assembly can be adjusted by adjusting the position of the connecting assembly on the electric cylinder shaft. In addition, the connecting assembly can also enable the booster electric cylinder assembly and the booster oil cylinder assembly to be accurately aligned.
