Two groups of buckles 101 are arranged at both ends of the drum body 1, and a bracket 2 is arranged on the side of the buckle 101 away from the drum body 1. The bracket 2 is provided with a connecting disk 4 of a rectangular structure, and a connecting groove 402 is provided inwardly at the connection between the connecting disk 4 and the main turntable 3, and a limiting groove 401 is provided at the connection between the connecting disk 4 and the limiting rod 303 of the main turntable 3, and a knob 404 is rotatably connected to the side of the connecting disk 4 away from the cylinder 1, and a second connecting rod 403 is provided on the side of the knob 404 close to the first connecting rod 304, and the second connecting rod 403 is threadedly connected to the first connecting rod 304.

[0021] The cross-sectional shape and size of the connecting groove 402 of the connecting disk 4 are consistent with the cross-sectional shape and size of the main turntable 3, and the connecting disk 4 is slidably connected to the main turntable 3 through the connecting groove 402. Through the sliding movement of the main turntable 3, the buckle 101 of the cylinder 1 can be conveniently connected, and the installation and disassembly of the cylinder 1 are convenient. An outwardly protruding annular structure is provided on the side of the second connecting rod 403, and the second connecting rod 403 is rotationally connected to the connecting disk 4 through the annular structure, so as to avoid the second connecting rod 403 from rotating and moving, and better drive the first connecting rod 304 to move.

[0022] The main turntable 3 is inlaid on the side of the connecting disk 4 close to the buckle 101, and a secondary turntable 301 is arranged at the connection between the main turntable 3 and the buckle 101. The secondary turntable 301 is rotatably connected to the main turntable 3. A card slot 302 is provided at the connection between the secondary turntable 301 and the buckle 101, and the cross-sectional shape and size of the card slot 302 are consistent with the cross-sectional rotation size of the buckle 101. The card slot 302 can be moved by horizontal movement of the main turntable 3 to complete the insertion and extraction with the buckle 101. Four cards are fixed on the side of the main turntable 3 away from the buckle 101. A group of limiting rods 303 are provided, and a first connecting rod 304 is also provided in the middle position of the four groups of limiting rods 303. The four groups of limiting rods 303 are distributed on the side of the first connecting rod 304 with the first connecting rod 304 as the center. The four groups of limiting rods 303 can increase the stability of the sliding connection between the main turntable 3 and the connecting disk 4. A slider 405 is provided at the connection between the connecting disk 4 and the bracket 2. A sliding groove 201 is provided at the connection between the bracket 2 and the slider 405. The connecting disk 4 is slidingly connected to the bracket 2 through the sliding groove 201 and the slider 405.

[0023] When the embodiment of the present application is used, the barrel 1 and the secondary turntable 301 can be assembled by inserting the buckles 101 at both ends of the barrel 1 into the slots 302 of the secondary turntable 301, and then the barrel 1 can be rotated by rotating the secondary turntable 301 and the main turntable 3, and the position of the main turntable 3 can be adjusted by rotating the knob 404 on the connecting disk 4;

[0024] By rotating the knob 404, the second connecting rod 403 on one side is driven, and the second connecting rod 403 drives the first connecting rod 304 to move through the threaded structure connected to the first connecting rod 304, so that the main turntable 3 can be driven to move inside the connecting groove 402 of the connecting disk 4. In this process, the limiting rod 303 set on the main turntable 3 will also slide between the limiting groove 401 of the connecting disk 4 to increase the stability of the sliding connection between the main turntable 3 and the connecting disk 4. During the movement of the main turntable 3, the spacing of the auxiliary turntable 301 can be adjusted under the premise of changing the spacing of the brackets 2 at both ends of the cylinder 1. Therefore, after rotating the knob 404, the main turntable 3 can be moved, so that the slot 302 of the auxiliary turntable 301 is disengaged from the buckle 101 of the cylinder 1. On the contrary, the buckle 101 can be inserted into the card slot 302, which is convenient for the installation and disassembly of the cylinder 1.
