[0022] In the above structure, relatively parallel and symmetrical guide rails 3 are provided on the left and right sides of the bowl basket 2. Correspondingly, two rotating wheels 4 are respectively provided on the left and right side walls of the inner container 1. The two rotating wheels 4 are both rollingly connected to the inner grooves 30 on the outer sides of the guide rails 3, so that the bowl basket 2 can push and pull relative to the inner container 1. On this basis, the front and rear ends of the guide rail 3 are respectively engaged and connected with a front clamping block 5 and a rear clamping block 6. For the rear end of the guide rail 3, an L-shaped covering portion 31 is provided at the rear end of the guide rail 3. The L-shaped covering portion 31 is bent outwardly so as to cover the rear end of the rear clamping block 6. Under the abutting cooperation of the L-shaped covering portion 31, the impact stress of the bowl basket 2 when it moves into place is transferred to the L-shaped covering portion 31 and the guide rail 3, so that the connection relationship between the rear clamping block 6 and the guide rail 3 is more stable and reliable. Compared with the prior art, the utility model can reliably fix the rear clamping block, thereby improving the movement stability of the push-pull bowl basket and the service life of the guide rail mechanism.
