## Claims

### Claim 1

A ball practice device comprises:
a frame;
a net attached to the frame, the net being connected to the frame by a connecting member which the net can be disassembled from;
a base bracket; and
a supporting assembly interposed between the frame and the base bracket, the supporting assembly being configured for supporting the frame together with the base bracket,
wherein the frame comprises a lower segment, two side segments respectively adjoining two ends of the lower segment, and an upper segment opposite to the lower segment, the base bracket comprising a connecting portion, two side portions adjoining two ends of the connecting portion, and a portion opposite to the connecting portion, the lower segment of the frame being coupled to the connecting portion of the base bracket by a connecting mechanism which can be disassembled to depart the frame from the base bracket,
wherein the supporting assembly comprises two sleeves separately coupled to a side segment of the frame and a respective side portion of the base bracket and a supporting rod, the supporting rod having two ends for inserting into the sleeves, and
wherein a snap fastener is connected between the two sleeves, the snap fastener being configured for straining the two sleeves so as to hold the two ends of the supporting rod in the two sleeves and allow the supporting rod to support the frame together with the base bracket.

### Claim 2 (depends on 1)

The device as claimed in claim 1, wherein the connecting member comprises a plurality of hooks for hitching net threads of the net thereon so that the net is attached to the frame.

### Claim 3 (depends on 1)

### Claim 4 (depends on 1)

The device as claimed in claim 1, wherein each sleeve has an opening end allowing for insertion of the supporting rod and a sealed end secured to the respective side segment/side portion.

### Claim 5 (depends on 1)

The device as claimed in claim 1, wherein the supporting rod comprises a plurality of segments which can be folded and adjustable in length.

### Claim 6 (depends on 1)

The device as claimed in claim 1, wherein the connecting mechanism comprises one of adherent strips, buttons, snapping mechanism, and a zipper sewed into a fabric tape.

### Claim 7 (depends on 1)
