[0012] Preferably, the bottom of the connecting seat is provided with a connecting seat trapezoidal surface, and the top of the outer positioning seat is provided with a positioning seat trapezoidal surface, and when the outer positioning seat and the connecting seat are in a connected state, the positioning seat trapezoidal surface and the connecting seat trapezoidal surface abut against each other. The connecting seat trapezoidal surface and the positioning seat trapezoidal surface can play a guiding role when the outer positioning seat is installed, and when the connecting seat trapezoidal surface and the positioning seat trapezoidal surface contact and abut against each other, the positioning of the outer positioning seat and the connecting seat is completed.

[0013] Preferably, the machine is provided with a tensioning shaft arranged parallel to the driving shaft on the side where the driving shaft is located, and the connecting seat is provided with a tensioning shaft sliding groove for positioning the end of the tensioning shaft. The tensioning shaft sliding groove provides a sliding space for the tensioning shaft, which is convenient for disassembly and installation of the endless belt.

[0014] Preferably, the machine is provided with a deflection correction shaft arranged parallel to the driven shaft on the side where the driven shaft is located, and the connecting seat is provided with a deflection correction shaft sliding groove for positioning the end of the deflection correction shaft.
