[0030] In this embodiment: by connecting the motor 3 to electricity and running it, the output shaft of the motor 3 in the running state drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the stirring blade 5 in the installed state to rotate, so that the stirring blade 5 in the rotating state uniformly mixes the various mixed materials inside the color mixing tank 1.

[0031] Please refer to Figure 3, the first locking assembly includes a fixing seat 601, an external thread 602, a docking piece 603 and an internal thread 604;

[0032] The fixing seat 601 is fixedly connected to the top of the rotating shaft 4, the external thread 602 is set on the outer wall of the fixing seat 601, the docking piece 603 is detachably connected to the fixing seat 601, and the fixing seat 601 and the docking piece 603 are both hollow structures, and the internal thread 604 is set on the inner wall of the docking piece 603.

[0033] In this embodiment, the docking member 603 drives the internal thread 604 provided on the inner wall to be threadedly connected with the external thread 602 provided on the outside of the fixing seat 601, and the internal thread 604 and the external thread 602 in the threaded connection state fix the docking member 603 and the fixing seat 601.

[0034] Please refer to Figure 3 The internal thread 604 and the external thread 602 are threadedly connected, and the internal thread 604 and the external thread 602 in the threaded connection state are used to fix and install the docking piece 603 and the fixing seat 601.

[0035] In this embodiment, the internal thread 604 and the external thread 602 are separated, and the internal thread 604 and the external thread 602 in the separated state can disassemble the docking piece 603 and the fixing seat 601 .

[0036] Please refer to Figure 4 , the second locking assembly includes a connecting shaft 605, a pressing block 606, a telescopic rod 607, a first spring 608, a receiving groove 609, a second spring 6010 and a stopper 6011;

[0037] The telescopic rod 607 includes a sleeve and a sliding rod, and the sliding rod is slidably connected to the inner cavity of the sleeve;

[0038] The connecting shaft 605 is rotatably connected to the inner wall of the docking piece 603, the pressing block 606 is fixedly connected to the end of the connecting shaft 605, the telescopic rod 607 is installed inside the fixed seat 601, the first spring 608 is sleeved on the outside of the telescopic rod 607, and the two ends of the first spring 608 are respectively fixedly connected to the sleeve and the sliding rod, the accommodating groove 609 is opened on the inner wall of the fixed seat 601, the second spring 6010 is installed inside the accommodating groove 609, the stopper 6011 is slidably connected to the inside of the accommodating groove 609 and extends to the outside thereof, and the stopper 6011 is fixedly connected to the end of the second spring 6010.

[0039] In this embodiment, the pressing block 606 is driven to move downward by the docking member 603 through the connecting shaft 605, and the pressing block 606 in the descending state contacts the stopper 6011. Since the end surfaces of the pressing block 606 and the stopper 6011 in contact are both inclined, the pressing block 606 squeezes the stopper 6011 along the two inclined ends, and the stopper 6011 in the compressed state transmits the force to the second spring 6010, and the compressed second spring 6010 assists the stopper 6011 to move into the receiving groove 609. The pressure block 606 moves, and the descending state contacts the top of the telescopic rod 607, transferring the pressure to the telescopic rod 607 and the first spring 608, so that the telescopic rod 607 and the first spring 608 are compressed. When the pressure block 606 is separated from the stopper 6011 after the descent is completed, the pressure of the second spring 6010 disappears, so that the second spring 6010 in the reset state drives the stopper 6011 to move to the outside of the accommodating groove 609, and the stopper 6011 in the state of moving to the outside contacts the pressure block 606.

[0040] Please refer to Figure 4 The end surfaces of the pressing block 606 that contact the stopper 6011 are both inclined structures, and the pressing block 606 in the lifting state is used to squeeze the stopper 6011.

[0041] In this embodiment, the pressing block 606 is assisted to move upward by the telescopic rod 607 and the first spring 608 in the reset state, and the pressing block 606 in the ascending state squeezes the stopper 6011 into the accommodating groove 609 through the two inclined ends, so that the pressing block 606 is separated from the stopper 6011.

[0042] Please refer to Figure 2 The stirring blade 5 is fixedly connected to the outer wall of the docking member 603 through a connecting ring, and the installed stirring blade 5 is used to evenly mix the various mixed materials inside the color mixing tank 1.

[0043] In this embodiment, the rotating shaft 4 drives the installed stirring blade 5 to rotate, so that the rotating stirring blade 5 evenly mixes the various mixed materials in the color mixing tank 1.

[0044] Working principle: when the stirring blade 5 needs to be installed, align the fixing seat 601 with the docking piece 603, and rotate the docking piece 603 by hand to make the docking piece 603 drive the internal thread 604 set on the inner wall to be threadedly connected with the external thread 602 set on the outside of the fixing seat 601, and the docking piece 603 drives the pressing block 606 to move downward through the connecting shaft 605, and the pressing block 606 in the descending state contacts with the stopper 6011, because the end surfaces of the pressing block 606 and the stopper 6011 in contact are both inclined structures, the pressing block 606 squeezes the stopper 6011 along the two inclined ends, and the stopper 6011 in the compressed state transfers the force to the second spring 6010, and the compressed second spring 6010 assists the stopper 6011 to move toward the inside of the accommodating groove 609, and the pressing block 606 in the descending state contacts with the top of the telescopic rod 607, transferring the pressure to the telescopic rod 6 07. On the first spring 608, the telescopic rod 607 and the first spring 608 are compressed. When the pressure block 606 is completely lowered and separated from the stopper 6011, the pressure of the second spring 6010 disappears, so that the second spring 6010 in the reset state drives the stopper 6011 to move to the outside of the accommodating groove 609. The stopper 6011 in the state of moving to the outside abuts against the pressure block 606. At the same time, the internal thread 604 and the external thread 602 in the threaded connection state fix the docking piece 603 and the fixing seat 601, and then the stirring blade 5 is installed inside the color mixing tank 1. When the mixed materials need to be stirred and mixed, the motor 3 is powered on and operated. The output shaft of the running motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the stirring blade 5 in the installed state to rotate, so that the stirring blade 5 in the rotating state evenly mixes the various mixed materials inside the color mixing tank 1.

[0045] When the stirring blade 5 needs to be disassembled, the internal thread 604 and the external thread 602 are separated, and the docking piece 603 drives the pressure block 606 to move upward through the connecting shaft 605. At the same time, the telescopic rod 607 and the first spring 608 in the reset state assist the pressure block 606 to move upward. The pressure block 606 in the ascending state squeezes the stopper 6011 into the accommodating groove 609 through the two inclined ends, and the pressure block 606 is separated from the stopper 6011. At the same time, the docking piece 603 is separated from the fixing seat 601, so that the stirring blade 5 can be easily disassembled, which can avoid the operator's hands being scratched when cleaning the stirring blade 5. The stirring blade 5 can be disassembled and cleaned, which has a protective effect on the operator.

[0046] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
