1. the opening flange plastic bucket carrying forklift clamps the plastic bucket through the clamping frame, and the bottom and the top of the plastic bucket are limited respectively through the bucket bottom bearing bracket and the bucket top limiting frame on the clamping frame. It had both avoided the plastic drum to drop from the holding frame bottom in the transportation, and when fork truck made the holding frame drive the plastic drum upset through rotary regulating mechanism and emptyd the raw materials in addition, avoided the plastic drum to follow the holding frame top and to the landing to one side, improved the job stabilization nature when plastic drum transport and raw materials are emptyd, effectively prevented the extravagant damage with the plastic drum of raw materials, avoided the plastic drum or the raw materials injury that drop to producers, improve production security.

2. The second limiting strip is blocked at the opening flange of the plastic barrel. Because the diameter of plastic drum narrows from the middle part to the top opening part gradually, through letting the lateral wall looks adaptation of first spacing and plastic drum, can shorten the required length of second spacing. The position of the second limiting strip in contact with the plastic barrel opening flange is closer to the first limiting strip, the joint of the second limiting strip and the first limiting strip is not easy to deform, and the structural stability of the barrel top limiting frame is kept. Meanwhile, the first limiting strip can also play a certain role in limiting the plastic barrel to slide downwards. The third spacing strip can reduce the range of rocking on plastic drum upper portion.

3. First clamping part and second clamping part all include three and pass through hinge articulated grip block in proper order. Thereby when tightly pressing from both sides tight plastic drum through straining mechanism tightens up the interval of the relative edge of first clamping part and second clamping part, because first clamping part and second clamping part are the components of a whole that can function independently structure, rotatable between the adjacent grip block, then reduced the stress that the clamping part locally received, delayed its stress fatigue to the life of extension clamping part.

4. The torque increasing gear set is arranged in the rotation adjusting mechanism, so that the resistance of the hand wheel is reduced, an operator can rotate the hand wheel with smaller strength, the clamping frame is driven to rotate the plastic barrel, and the operation difficulty is reduced.

The invention will become more apparent from the following description when taken in conjunction with the accompanying drawings which illustrate embodiments of the invention.
