[0005] The back box is a rectangular shell structure composed of a top plate, a back plate, and left and right side plates. On the left and right side plates at the lower end of the back box, there are respectively two symmetrically arranged shaft holes on the left and right. Between the left and right side plates above the shaft holes, there is a support plate. A through slot parallel to the axis of the shaft hole is provided on the support plate, and the through slot is an elongated hole that penetrates the support plate vertically. A longitudinal positioning plate is connected to the support plate in front of the through slot and is parallel to the through slot. A number of horizontally arranged positioning holes are provided on the positioning plate. On the left and right side plates of the back box, there are respectively two symmetrically arranged and perpendicular to the back plate chutes. The lock rod is arranged parallel to the positioning plate and is located behind the through slot on the support plate. The left and right ends of the lock rod are respectively connected to the left and right chutes. A number of lock heads respectively cooperating with the positioning holes on the positioning plate are provided on the lock rod. A spring is provided between the lock rod and the back plate. The front cover is a rectangular shell structure composed of a top plate, a front panel, and left and right side plates. On the left and right side plates at the lower end of the front cover, there are respectively two symmetrically arranged shaft holes on the left and right. On the left and right side plates of the front cover, there are two left and right driving heads respectively corresponding to the left and right chutes on the back box. The front cover is arranged in front of the back box. The left and right shaft holes on the front cover and the back box are respectively connected to the left and right shaft necks of the rotating shaft. Transverse partitions are respectively provided below the top plates of the front cover and the back box. Front pressing strips and rear pressing strips are respectively provided between the top plates of the front cover and the back box and the transverse partitions. The front pressing strips and the rear pressing strips are both rectangular column structures. On the transverse partitions of the front cover and the back box, there are respectively two front left and right hooks and two rear left and right hooks. The hook is jointly composed of a horizontal support rod and a hook rod vertically connected to the outer end of the support rod through a hinge. The hook rod on the hook can fold inward around the hinge and can be vertically reset through elasticity. The front and rear left hooks are arranged corresponding to each other front and rear and are offset left and right. The front and rear right hooks are arranged corresponding to each other front and rear and are offset left and right. Front and rear insertion holes respectively corresponding to the rear left and right hooks and the front left and right hooks are provided on the front pressing strips and the rear pressing strips. The insertion holes are grooves for receiving the hooks.

[0006] The garbage bag is a rectangular pocket structure. A number of horizontally arranged finger holes are evenly provided at the upper end of the garbage bag. The finger holes are through holes corresponding to the positioning holes on the positioning plate. Four horizontally arranged hanging holes are provided below the finger holes. The hanging holes are through holes corresponding to the hooks. On the back bag surface of the garbage bag, a through seam longitudinally connecting the hanging holes is provided on the upper bag surface corresponding to the hanging holes of the front left and right hooks. A through seam longitudinally connecting the hanging holes is provided on the lower bag surface corresponding to the hanging holes of the rear left and right hooks. On the front bag surface of the garbage bag, a through seam longitudinally connecting the hanging holes is provided on the lower bag surface corresponding to the hanging holes of the front left and right hooks. A through seam longitudinally connecting the hanging holes is provided on the upper bag surface corresponding to the hanging holes of the rear left and right hooks. The through seam is a slot for cooperating with the hook rod on the hook. A number of garbage bags are connected end to end and wound around the rotating shaft. A splitting band is provided between the sealing band at the lower end of the upper garbage bag and the finger holes at the upper end of the lower garbage bag. The splitting band is composed of a number of horizontally arranged small through holes.

[0007] In use, the upper end of the garbage bag is passed through the through groove on the support plate and the gap between the locking rod and the positioning plate and moved upward. When the hanging holes on the upper garbage bag and the finger holes on the lower garbage bag are respectively aligned with the upper hook and the lower positioning hole, the locking rod can drive the lock head to insert into the finger hole and the positioning hole under the action of the spring to lock the garbage bag. When closing the front cover around the rotating shaft, the front pressing strip and the rear pressing strip can press the upper end of the garbage bag, and each hook will respectively pass through the corresponding hanging hole on the garbage bag and enter each jack, and the locking rod on the hook will fold and pass through the hanging hole on the garbage bag. When opening the front cover, the hook will pass through the hanging hole with the upper seam and hook the hanging hole without the upper seam through the upright locking rod, and thus the bag mouth of the garbage bag in the box will be unfolded.

[0008] When replacing the garbage bag, the locking rod is squeezed through the driving head to release the locking of the garbage bag, and then the garbage bag is lifted upward through the finger hole. When the support rods on each hook move downward to the bottom position of the lower seam of the hanging hole, the hook and the upright locking rod can be separated from the garbage bag through the hanging hole and the lower seam. Continue to lift the garbage bag upward until the locking rod and the positioning plate lock the garbage bag again, then the front cover can be closed and the upper end of the next garbage bag can be fixed through the front pressing strip, the rear pressing strip and each hook, and finally the old garbage bag can be removed along the splitting strip.

[0009] The beneficial effect of the present invention is that the garbage bag in the box is replaced semi-automatically in a mechanical manner, thereby reducing the contact of the human body with the garbage bin and the garbage bag. BRIEF DESCRIPTION OF THE DRAWINGS
