The electrical box 3 is mounted on the mounting base 2.

[0025] In this embodiment, a gearbox 12 is provided on the mounting platform 11, and an extrusion screw is connected to the gearbox 12; a bracket 15 is provided on the main unit base 1, and an extrusion housing 16 is provided on the bracket 15. The extrusion housing 16 is connected to the gearbox 12, and the extrusion screw rotates inside the extrusion housing 16; a feed port 161 is opened at the top of the extrusion housing 16.

[0026] In this embodiment, a fixed platform 13 is formed on the base 1 of the main unit, and a drive motor 14 is provided on the fixed platform 13. The drive motor 14 is connected to the reduction gearbox 12. The top surface of the fixed platform 13 is flush with the top surface of the mounting platform 11.

[0027] In this embodiment, a first mounting block 111 is provided on the left side wall of the mounting platform 11, and the first rotating plate 41 is fixed to the first mounting block 111 by screws.

[0028] In this embodiment, a second mounting block 21 is provided on the left side wall of the mounting base 2, and the second rotating plate 42 is fixed to the second mounting block 21 by screws.

[0029] In this embodiment, a first rotating sleeve 411 is formed on the side wall of the first rotating plate 41, and two second rotating sleeves 421 are formed on the side wall of the second rotating plate 42. The two second rotating sleeves 421 are arranged vertically at intervals, and the first rotating sleeve 411 is located between the two second rotating sleeves 421. The rotating shaft 43 passes through the two second rotating sleeves 421 and the first rotating sleeve 411 respectively.

[0030] In this embodiment, a support bracket 17 is detachably installed on the right side of the front end of the main unit base 1. When the mounting base 2 is located on the front side of the main unit base 1, the support bracket 17 supports the mounting base 2. The support bracket 17 has multiple first connecting holes 171, and the front end of the main unit base 1 has multiple second connecting holes 18. The multiple first connecting holes 171 correspond one-to-one with the multiple second connecting holes 18.
