The telescopic clamping members (42) and the fixing and adjusting members (43) respectively extend outward from the center of the triangular base (41), and the extension radius of the fixing and adjusting members (43) is smaller than that of the telescopic clamping members (42).

10. The switching method according to claim 9, characterized in that, The bottom of the positioning support column (44) is disc-shaped and is locked and connected in the sunken groove by screws; The sunken groove (41a) is used for accommodating a one-word cover opening structure of the one-word cover opening assembly (30), and the positioning support column (44) is connected to a positioning hole at the center of the one-word cover opening structure; Each of the fixing and adjusting members (43) is further provided with a lower edge protrusion (41b) corresponding to each corner position, and a parallel relationship is formed between the lower edge protrusion (41b) and the telescopic clamping member (42). The plane where the lower edge of the lower edge protrusion (41b) is located is higher than the height of the clamping part of the telescopic clamping member (42), but lower than the height of the installation member at the center of the bottom surface of the triangular base (41); An adjustable length limiting screw is installed on the lower edge protrusion (41b) to limit the inward contraction of the clamping part of the telescopic clamping member (42), so as to protect the IBC bucket cover; Corresponding to the installation positions of the telescopic clamping members (42) and the fixing and adjusting members (43), radially extending telescopic clamping grooves (41c) and fixing and adjusting grooves (41d) are respectively formed in the upper surface of the triangular base (41), and the telescopic clamping grooves (41c) and the fixing and adjusting grooves (41d) are T-shaped grooves; A ball positioning hole (41e) is arranged on the bottom surface of the fixing and adjusting groove (41d), and two or more than two matching holes (43a) are correspondingly arranged on the matching surface of the fixing and adjusting member (43) to match and position with the ball in the ball positioning hole (41e); The fixing and adjusting member (43) is provided with an inward adjusting clamping groove (43b) on the outside, so that the position of the fixing and adjusting member (43) in the fixing and adjusting groove (41d) can be adjusted by means of external tools, and the locking groove connection with the one-word cover opening assembly (30) is realized. The upper part of the fixed adjusting part (43) is further provided with a locking block (43c) which is higher than the top mounting surface of the triangular base (41) and is arranged in T shape transversely to the main body structure of the fixed adjusting part (43), and the locking block (43c) and the adjusting clamping groove (43b) are located at the inner and outer two ends of the fixed adjusting part (43); The upper part of the telescopic clamping part (42) is provided with a driving block (42a) which is connected with the driving tooth of the one-character type uncovering assembly (30) to drive the telescopic clamping part (42) through the driving tooth.
