A ball server includes a server seat, a movable rod inserted into the server seat, an elastomer, a touch plate, and a delay element within the server seat. In using, the movable rod is pressed so as to buckle the touch plate and the movable rod is interacted with the delay element, the ball will flatly place on the movable rod. When the ball server is actuated, the movable rod will be driven by the delay element so that it rises slowly, but after a time period, the action of the delay element is released and the movable rod rises rapidly and at the same time, the ball rises. When the movable rod is operated by the delay element, the batter can prepare for next beating.

1. A ball server comprising: a server seat flatly placed one a ground; a movable rod having a first part in the server seat and a second part out of the server seat, a top of the second part having a ball seat; a bottom of the first part having a buckle plate; and the buckle plate having a first

1. A ball server comprising: a server seat flatly placed one a ground; a movable rod having a first part in the server seat and a second part out of the server seat, a top of the second part having a ball seat; a bottom of the first part having a buckle plate; and the buckle plate having a first buckle and a driving portion; an elastomer at a bottom of the server seat for ejecting the movable rod upwards; a touch plate pivotally installed at one side of a bottom of the server seat and having a second buckle having a portion within the server seat to be buckled with the first buckle so as to confine an ejecting length of the movable rod; and a delay element in the server seat and having a driving element which is interacted with the driving portion of the buckle plate; the delay element further having a delay unit for delaying an interaction time of the driving portion of the buckle plate and the driving element; and wherein when serving a ball, the movable rod is pressed toward the server seat, then the first buckle of the buckle plate is buckled to the second buckle of the touch plate so that the movable rod is buckled to the touch plate and the driving portion of the buckle plate is in contact with the driving element of the delay element; thereby, the movable rod is interacted with the delay element; when the ball is flatly placed on the ball seat at the top of the movable rod, the elastomer at the bottom of the server seat is stored with a potential energy for ejecting the movable rod; when the ball server is operated, the movable rod is ejected upwards due to the action of the elastomer; by action of the delay element, the movable rod will rise up slowly; when the movable rod is released from the action of the delay element; the movable rod rises up rapidly with being driven by the delay element and thus the ball also rises up; when the movable rod is operated by the delay element, the batter prepares for next beating. 2. The ball server as claimed in claim 1, wherein the ball server includes a server seat which is formed by two casing halves; an interior of the server seat has a longitudinal through hole; a middle section of the through hole is installed with a concave seat for receiving the delay element; a side of the bottom of the through hole has a slot; besides, a bottom of the server seat has a connecting seat for being locked to a bottom plate; thereby, the server seat is steadily placed on a ground. 3. The ball server as claimed in claim 1, further comprising a restoring element for moving the touch plate to return to the unbuckling condition. 4. The ball server as claimed in claim 1, wherein the delay element has a gear set for forming the delay unit and the gear set is installed in a case seat of the delay element; the driving element is a gear extended out of the case seat; the driving portion of the buckle plate is a rack with a predetermined length and is engagable with the driving element of the delay element. 5. The ball server as claimed in claim 4, wherein the delay unit of the delay element has an effect of delaying the rack by designing the number of teeth of the gear set. 6. The ball server as claimed in claim 4, wherein the delay unit of the delay element has an effect of delaying the rack by rotation of the gear set. 7. The ball server as claimed in claim 4, wherein the delay unit of the delay element has an effect of delaying the rack by designing the number of teeth of the gear set and by rotation of the gear set. 8. The ball server as claimed in claim 1, wherein the elastomer is a compressing spring positioned by a rod.
