The connecting pipe 221 is formed on and protrudes from the inner surface of the covering plate 22, extends in the outer side of the rotating mount 21, and engages one of the inserting holes 214 to hold the covering plate 22 with the rotating mount 21. The connecting pipe 221 is hollow and has a free end and an external surface. The free end of the connecting pipe 221 extends in the rotating mount 21 via a corresponding inserting hole 214. The abutting ring 222 is formed on and protrudes from the external surface of the connecting pipe 221 at the free end, and abuts against the inner side of the rotating mount 21.</p>
<p id="p0018" num="0018">The cutting grooves 223 are axially formed through the external surface of the connecting pipe 221 and the abutting ring 222 to enable the connecting<!-- EPO <DP n="8"> --> pipe 221 to deform relative to the corresponding inserting hole 214 of the rotating mount 21. Then, the abutting ring 222 can be passed through the corresponding inserting hole 214 to abut against the inner side of the rotating mount 21 to hold the covering plate 22 with the rotating mount 21. The track grooves 224 are formed through the curved outer edge of the covering plate 22, are space apart from each other at intervals, align with some of the notches 215 of the rotating mount 21, and each one of the track grooves 224 has a width. The width of the track groove 224 is wider than the width of a corresponding notch 215 of the rotating mount 21. The guiding channel 225 is formed in the flat inner edge of the covering plate 22. In addition, each one of the track grooves 224 of the operating set 20 communicates with one of the track grooves 224 of one of the adjacent operating sets 20.</p>
<p id="p0019" num="0019">With reference to <figref idref="f0001">Fig. 1</figref>, when the covering plates 22 are mounted on the rotating mount 21, the operating set 20 has a sliding groove 25 formed between the guiding channels 225 of the covering plates 22, and the sliding groove 25 aligns with two of the notches 215 of the rotating mount 21. That is, the notches 215 of the rotating mount 21 align with the sliding groove 25 and the track grooves 224 of the covering plates 22. Furthermore, the sliding groove 25 of the operating set 20 communicates with the two sliding grooves 25 of two of the adjacent operating sets 20. Preferably, each one of the covering plates 22 has a color.</p>
<p id="p0020" num="0020">The sliding sheets 23 are movably mounted in the track grooves 224 of the covering plates 22 and the sliding groove 25 of the operating set 20 to cover the rotating mount 21. Each one of the sliding sheets 23 is a curved and<!-- EPO <DP n="9"> --> rectangular sheet and has an outer surface and a mark 231. The outer surface of the sliding sheet 23 is exposed from one of the track grooves 224 or the sliding groove 25 of the operating set 20. The mark 231 is formed on the outer surface of the sliding sheet 23, and the mark 231 can be a numeral or an English alphabet as shown in <figref idref="f0008">Fig. 8</figref>.</p>
<p id="p0021" num="0021">Additionally, the mark 231 of the sliding sheet also can be a pattern of Chinese Animal Zodiac, Constellations, Poker or Numerology. Furthermore, the outer surface and the mark 231 of the sliding sheet 23 have different colors. Preferably, the color of the outer surface of the sliding sheet 23 is same or different from the colors of the two covering plates 22. The amount of the sliding sheets 23 of one of the operating sets 20 is fewer than amount of the other operating sets 20 to form a gap on the operating set 20, and this can enable the sliding sheets 23 of the operating set 20 to move to another operating set 20 via the gap.</p>
<p id="p0022" num="0022">In use, with reference to <figref idref="f0005">Fig. 5</figref>, a user can turn the educational ball over to enable the operating set 20 that has fewer sliding sheets 23 to move to a top of the educational ball. In the first embodiment of an educational ball, the gap is formed in the sliding groove 25 of the corresponding operating set 20. With reference to <figref idref="f0006">Fig. 6</figref>, the user can rotate one of the adjacent operating sets 20 to enable one of the sliding sheets 23 of the adjacent operating set 20 to align with the gap. Then, the user can push the corresponding sliding sheet 23 to move into the gap to fill the sliding groove 25 of the operating set 20 that has fewer sliding sheets 23 as shown in <figref idref="f0007">Fig. 7</figref>, and the gap is moved and formed on the adjacent operating set 20.<!-- EPO <DP n="10"> --></p>
<p id="p0023" num="0023">According to the above-mentioned operation, the user also can rotate two adjacent operating sets 20 to enable the gap to align with one of the track grooves 224 of one of the two adjacent operating sets 20 to form different spatial arrangements. In addition, each one of the operating sets 20 can be rotated relative to the four adjacent operating sets 20 to move the sliding sheets 23 between the operating sets 20. Furthermore, the user can move the sliding sheets 23 in the track grooves 224 annularly according to the order and sequence of numerals or English alphabets or move the sliding sheets 23 in the sliding grooves 25 to align with each other according to the order and sequence of numerals or English alphabets. In addition, the user also can push the sliding sheets 23 with same colors to move in the track grooves 224 and the sliding groove 25 of one of the operating sets 20. Therefore, the educational ball in accordance with the present invention can provide different spatial arrangements and modes of operation, and this can increase operational variability, fun and challenge of using the educational ball. Then, the training effect of mental, spatial concepts and logical thinking for the users can be improved by the educational ball of the present invention.</p>
<p id="p0024" num="0024">With reference to <figref idref="f0008">Fig. 8</figref>, a second embodiment of an educational ball in accordance with the present invention is substantially the same as the first embodiment except for the following features. Only one of the operating sets 20 has a sliding groove 25, and the mark 231 of each one of the sliding sheets 23 is an English alphabet.</p>
<p id="p0025" num="0025">With reference to <figref idref="f0009">Fig. 9</figref>, a third embodiment of an educational ball in accordance with the present invention is substantially the same as the first<!-- EPO <DP n="11"> --> embodiment except for the following features. Each rotating mount 21A of the operating sets 20A does not have the engaging ring 212 and the cutting slots 213, and the engaging jacket 211 cannot be deformed.
