1. A transmission device for lifting a sickbed comprising:
a first casing made of 70% polyamide (PA) and 30% glass fiber, and the first casing including a first rotatable connection portion extending along a first axial line, a second rotatable connection portion connected with the first rotatable connection portion and extending along a second axial line, a first space defined between the first rotatable connection portion and the second rotatable connection portion, and multiple locking orifices passing through the first rotatable connection portion and the second rotatable connection portion, the first axial line being perpendicular to the second axial line;
a second casing made of 70% polyamide (PA) and 30% glass fiber, and the second casing including a third rotatable connection portion extending along the first axial line, a fourth rotatable connection portion connected with the third rotatable connection portion and extending along the second axial line, a second space defined between the third rotatable connection portion and the fourth rotatable connection portion, and multiple coupling orifices passing through the third rotatable connection portion and the fourth rotatable connection portion, the first space of the first casing and the second space of the second casing being connected to form an accommodation chamber;
a power input assembly including an input shaft rotatably accommodated in the first rotatable connection portion and the third rotatable connection portion, and the power input assembly including a first bevel gear connected on the input shaft;
a power output assembly including an output shaft rotatably received in the second rotatable connection portion and the fourth rotatable connection portion, and the power output assembly including a second bevel gear connected on the output shaft and meshing with the first bevel gear, the first bevel gear and the second bevel gear being received in the accommodation chamber; and
multiple screw elements inserted through the multiple coupling orifices of the second casing to screw with the multiple locking orifices of the first casing.
