The connecting device is a folding connecting mechanism, one end of which is hinged to the lower front part of the backboard 4, and the other end of which is connected to the rear end of the basket 1. The basket 1 is rotated downward from the horizontal state when in use to the vertical state, that is, it is converted into a folded state.

[0021] Specifically, the folding connection mechanism includes a connecting plate 1-1, a U-shaped member 1-2, an elastic oblique support 2, a fixing plate 3 and a latch shaft 8. The fixing plate 3 is fixedly connected to the front lower part of the backboard 4, the rear end of the basket 1 is fixedly connected to the front end of the connecting plate 1-1, the rear end of the connecting plate 1-1 is hinged to the upper part of the fixing plate 3 in a detachable manner, and the rear end of the basket 1 located below the connecting plate 1-1 is fixedly connected to the U-shaped member 1-2. The upper and lower ends of the elastic oblique support 2 are both provided with mounting holes, and a connecting bolt 7 is used to pass through the mounting hole at the upper end of the elastic oblique support 2 and the U-shaped member 1-2 to achieve a detachable connection. The lower part of the fixing plate 3 is provided with two latch holes corresponding to the mounting hole at the lower end of the elastic oblique support 2, and the latch shaft 8 is used to pass through the mounting hole at the lower end of the elastic oblique support 2 and the two latch holes on the fixing plate 3 to achieve a detachable connection. The above-mentioned basket 1 includes a basket ring and a net.

[0022] Furthermore, the upper edge of the above-mentioned fixed plate 3 is a flange bent forward, the front end of the flange is curled to form two sockets, and the rear end of the connecting plate 1-1 is curled to form a transverse socket, and the connecting bolts 7 are inserted into the transverse socket on the connecting plate 1-1 and the two sockets on the flange of the fixed plate 3 to achieve hinged connection.

[0023] Furthermore, two connecting plates are symmetrically arranged vertically on the front side of the fixing plate 3, and each connecting plate is provided with a pin hole.

[0024] Specifically: the above-mentioned elastic inclined support 2 includes a spring upper connecting seat 2-4, a spring lower connecting seat 2-5, a spring 2-1, an outer sleeve 2-2 and an inner sleeve 2-3, the spring 2-1 is arranged between the outer sleeve 2-2 and the inner sleeve 2-3, the above-mentioned mounting holes are respectively arranged on the spring upper connecting seat 2-4 and the spring lower connecting seat 2-5, the spring upper connecting seat 2-4 is connected to the U-shaped part 1-2 by a connecting bolt 7, and the spring lower connecting seat 2-5 is connected to the two latch holes on the fixed plate 3 using a latch shaft 8.
