An injection needle apparatus in which an operation for relatively moving an outer tube 4 and an inner tube 5 is performed to project and retract a needle body 12 from and into a distal end of the outer tube 4, and to carry out a movement of rotation of the needle body 12 at a predetermined angle by relative forward and backward movements of the outer tube 4 and inner tube 5 in their longitudinal directions every time the forward and backward movement operations is repeated, thereby enabling changing a direction of a needlepoint 14 of the needle body 12 at each angle.

The invention provides a basketball pass training device to solve the problem in the existing basketball pass training device that the passing angle is single, the passing quality is unstable, basketballs are not launched continuously, and basketball launching is limited by the shooting angle of trainees. The training device does not require personnel to carry out docking pass training to save manpower, and a cylinder is adopted to launch the basketballs, so that the passing quality becomes stable and reliable. At the same time, by means of alternative engagement of a third sector gear and a fourth sector gear with an arc rack, the angle of the launching cylinder in the vertical direction is adjustable. A horizontal angle adjusting device is also added to enable a swing rod to swing with an eighth gear to achieve angle adjustment of the launching cylinder in the horizontal direction. The basketball launching angle is varied, and the basketball catching difficulty of the trainees is improved. At the same time, the basketballs can be launched continuously when the trainees miss the basketballs, and the basketballs can be launched quickly when the trainees make a goal. The training time is saved, and the training quality is improved.
