A connecting plate 222 is fixed to the side wall of the hand-held block corresponding to the strip through hole 16. The connecting plate 222 is movable through the strip through hole 16 away from the side end of the hand-held block and is bonded and fixed to the fixed support plate 21 or fixed with bolts.

[0057] In some embodiments, the support plate 21 includes a fixed plate 211 and a length adjustment plate 212; the fixed plate 211 and the length adjustment plate 212 are arranged in parallel and are slidably connected along the plug-in direction of shell 11 and shell 2 12 to form a support plate structure with adjustable length; the fixed plate 211 is fixed to the bottom of the height adjustment part 22.

[0058] The total length of the support plate 21 can be changed by sliding and pulling the length adjustment plate 212 to adapt to the barrel cavity with varying lengths, thereby ensuring that the support plate 21 can adapt to supporting the bottom ends of garbage bags of different sizes.

[0059] In some embodiments, a water receiving tank 111 is provided at the bottom of the inner cavity of the shell 11 , and a water receiving tank 2 121 is provided at the bottom of the inner cavity of the shell 2 12 corresponding to and below the water receiving tank 111 .

[0060] The water receiving trough 111 and the water receiving trough 2 121 are used for collecting garbage and sewage leaked due to the damage of garbage bags.

[0061] Specifically, the water receiving trough 111 is an integral structure with the shell 11, and the water receiving trough 111 is formed at the bottom of the inner cavity of the shell 11; the water receiving trough 121 is an integral structure with the shell 2 12, and the water receiving trough 121 is formed at the bottom of the inner cavity of the shell 2 12.

[0063] When the sewage level in the water receiving tank 1 111 is higher than the water outlet 1111, it can be diverted from the water outlet 1111 to the water receiving tank 2 121; when the overlapping length of the shell 1 11 and the shell 2 12 is the largest and the volume of the barrel cavity 13 is the smallest, the water receiving tank 1 111 serves as the main water receiving tank. When there is too much sewage in the water receiving tank 1 111, it can flow through the water outlet 1111 to the water receiving tank 2 121. At this time, the water receiving tank 2 121 serves as a backup water receiving tank; when the shell 1 11 and the shell 2 are overlapped, the sewage level in the water receiving tank 1 111 is higher than the water outlet 1111, and the sewage level in the water receiving tank 1 111 is diverted from the water outlet 1111 to the water receiving tank 2 121. When the overlapping length of shell 11 and shell 2 is adjusted to the minimum, the volume of the corresponding barrel cavity 13 is the largest, and the water receiving trough 111 and the water receiving trough 2 121 serve together as the main water receiving troughs to receive sewage; during the relative pulling or closing movement of shell 11 and shell 2 12, the positions of water receiving trough 111 and the water receiving trough 2 121 change synchronously, so that the receiving area of ​​the water receiving trough notch always adapts to the size change of the barrel cavity bottom surface, so as to ensure that the leakage of the garbage bag can be completely collected in the water receiving trough.

[0064] In some embodiments, a limit block 113 is provided at the bottom of the open side end of shell one 11 and extends downward into water receiving trough two 121. The limit block 113 can prevent the bottom of shell one 11 from completely falling out of the inner cavity of shell two 12 when shell one 11 and shell two 12 are pulled.

[0065] Specifically, the limit block 113 can be a baffle integrally connected to the bottom end of the shell 11 or a stop nail threadedly connected to the bottom end of the shell 11.
