[0015] Preferably, the connection structure comprises oppositely arranged clamping rings, and the middle scraper rods are respectively fixed on the opposite clamping rings; the opposite clamping rings are sleeved on the stirring shaft and are tightened and fixed by bolts.

[0016] By adopting the above technical solution, the middle scraper rod is sleeved on the stirring shaft in the form of a clamping ring and tightened with bolts, so that the position of the clamping ring can be adjusted arbitrarily according to the height of the tank body, thereby improving the universality of the device.

[0017] Preferably, a connecting sleeve with an internal threaded notch is extended from the end of one of the clamping rings, and the connecting sleeve is inserted into another clamping ring, and a bolt is threadedly connected to the other clamping ring and inserted into and threadedly connected to the internal threaded notch.

[0018] By adopting the above technical solution, an extended connecting sleeve is provided with an internal thread groove to cover and protect the bolt, thereby reducing contact with the paint.
