So set up, can realize folding the accomodating of garbage bin, the expansion of big lid 300 and collet 100 all only need rotate the round pin axle with folding can, convenient and practical, simple and convenient swift occupies the bulky reduction when folding depositing, and is small, easily carries.

It should be noted that an anti-tipping structure may also be provided on the shoe 100.

For example; the bottom support 100 between the connecting lugs forms a limiting step, and the lower end of the connecting rod 200 is directly abutted against the limiting step between the connecting lugs for limiting so as to prevent the connecting rod 200 from toppling over under the action of gravity of the large cover part 300.

For example: one end of the shoe 100 is provided with a connecting part, the lower end of the connecting rod 200 is provided with a pair of connecting lugs, and a pin 220 passes through holes on the connecting part and the connecting lugs to rotatably connect the lower end of the connecting rod 200 to the shoe 100. Limiting bosses are arranged on two sides of the connecting part, and the lower end of the connecting rod 200 can abut against the limiting bosses to prevent the connecting rod 200 from toppling under the action of gravity of the large cover part 300.

Or an anti-toppling structure is arranged at the lower ends of the bottom support 100 and the connecting rod 200. The anti-toppling structure may employ conventional techniques in the art.

As shown in fig. 4, preferably, the single-support trash can without can wall further includes 2 symmetrically disposed support bars 240, and the upper ends of the support bars 240 are rotatably connected to the connecting rod 200; the bottom support 100 is symmetrically provided with 2 limiting grooves 130 corresponding to the supporting rods 240, an optical axis 140 is fixedly arranged in the bottom support 100 below the limiting grooves 130, and the lower ends of the supporting rods 240 are provided with grooves 241; in an operating state, the lower end of the supporting rod 240 is inserted into the limiting groove 130, and the groove 241 is clamped on the optical axis 140, so as to be supported and limited by the bottom bracket 100, and the connecting rod 200 is prevented from falling under the gravity of the big lid 300.

With this arrangement, the two sides of the limiting groove 130 can limit the position of the supporting rod 240 respectively, so as to prevent the connecting rod 200 and the large lid 30 from tipping forward and prevent the connecting rod 200 and the large lid 30 from tipping backward. The stability of the garbage can structure is further improved.

Preferably, as shown in fig. 4, the upper end of the connecting rod 200 has a pair of engaging lugs 250, a third through hole is provided on the engaging lug 250, a connecting portion 360 is provided on the top of the large lid portion 300, a fourth through hole is provided on the connecting portion 360, the pin shaft 210 passes through the third through hole and the fourth through hole to string up the engaging lug 250 and the connecting portion 360, so as to realize rotatable connection, two ends of the pin shaft are limited by an axial limiting structure (such as a nut, a shoulder, a snap spring, a nut, and an elastic buckle structure), and the side wall of the large lid portion 300 abuts against the upper end of the connecting rod 200.

Of course, those skilled in the art and others will understand that a pair of engaging lugs may be further provided at the upper end of the large lid portion 200, a third through hole is provided on the engaging lug, a connecting portion is provided at the top of the connecting rod, a fourth through hole is provided on the connecting portion, a pin shaft penetrates through the third through hole and the fourth through hole to string up the engaging lug and the connecting portion, so as to realize rotatable connection, both ends of the pin shaft are limited by an axial limiting structure, and the side wall of the large lid portion abuts against the upper end of the connecting rod.

When the garbage can of the embodiment is folded, the lower end of the connecting rod 200 and the bottom support 100 are rotationally folded by taking the pin shaft as a rotating shaft, and the upper end of the connecting rod 200 and the large cover 300 are rotationally folded by taking the pin shaft as a rotating shaft, so that the folding effect is realized. The volume of the folded garbage can is obviously reduced, and the folded garbage can is integrally cake-shaped and is convenient to store and transport.

Of course, it may also be: the upper end of the connecting rod 200 is rotatably connected to the large lid 300 by a pin so that the large lid 300 can be rotated and folded by using the pin as a rotating shaft, and the lower end of the connecting rod 200 is detachably and fixedly mounted to the bottom bracket 100.
