[0035] When the trowel knife needs to be replaced as a whole, the positioning bolt 4 is rotated to move the positioning bolt 4 out of the plug-in hole 3. During the movement of the positioning bolt 4, the clamping plate 5 is driven to move apart through the transmission plate 16, so that the connecting shaft 2 can be taken out from the plug-in hole 3, and the turntable 1 and the trowel knife can be quickly replaced together.

[0036] During assembly, the connecting shaft 2 is inserted into the plug hole 3, and the positioning bolt 4 is rotated in the opposite direction. The positioning bolt 4 moves relatively, and the positioning bolt 4 drives the clamping plate 5 to move relatively through the transmission plate 16. The positioning bolt 4 and the positioning rod 6 on the clamping plate 5 are respectively connected to the positioning hole 1 7 and the positioning hole 2 8 on the connecting shaft 2, thereby realizing the connection between the connecting shaft 2 and the turntable 1.

[0037] Combined with Figure 1-3 The turntable 1 is evenly provided with connecting rods 9 on the side, and a connecting groove 10 is provided on the lower end surface of the connecting rod 9. The separated end of the connecting groove 10 extends to the separated end of the connecting rod 9. A trowel 11 is provided below the connecting rod 9, and a connecting block 12 is provided on the upper end surface of the trowel 11. The connecting block 12 is slidably connected to the connecting groove 10. A second positioning bolt 13 is threadedly connected to the side of the connecting rod 9. The second positioning bolt 13 is exposed in the connecting groove 10. A through hole 14 is provided on the connecting block 12. The cross sections of the connecting groove 10 and the connecting block 12 are both T-shaped.

[0038] When a single trowel blade needs to be replaced, the positioning bolt 13 is removed, and the connecting block 12 on the trowel blade is removed from the connecting groove 10 on the connecting rod 9, thereby realizing the disassembly of the trowel blade.

[0039] During assembly, the connecting block 12 is placed into the connecting groove 10, and the positioning bolt 13 is rotated to pass through the through hole 14 of the connecting block to realize the assembly of the trowel. Since the cross-sections of the connecting groove 10 and the connecting block 12 are both T-shaped, the position of the trowel is well fixed during assembly, and it is easy to assemble.

[0041] Combined with Figure 3-4 The inner surface of the side of the plug hole 3 is symmetrically provided with a limit strip 17, the side of the connecting shaft 2 is symmetrically provided with a limit groove 18, the limit strip 17 is slidably connected with the limit groove 18, and the outer side of the connecting shaft 2 is sleeved with a limit sleeve 19.

[0042] When the connecting shaft 2 is connected to the plug hole 3, the limiting strip 17 is slidably connected with the limiting groove 18 to limit the direction of the connecting shaft 2, thereby ensuring the orientation of the positioning hole 1 7 and the positioning hole 2 8. The limiting sleeve 19 is slid downward, and the limiting sleeve 19 is sleeved on the outside of the clamping plate 5 to limit the position of the clamping plate 5.

[0043] Combined with Figure 1-2 A groove 1 is provided on the side of the turntable 1 at a position corresponding to the position of the positioning bolt 1 4 , and a groove 2 is provided on the side of the connecting rod 2 at a position corresponding to the position of the positioning bolt 2 13 .

[0044] The groove 1 and the groove 2 accommodate one end of the positioning bolt 1 4 and the one end of the positioning bolt 2 13 respectively.

[0045] The utility model and its implementation methods are described, and such description is not restrictive. The drawings are only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and implementation method similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
