The locking screw penetrates through a hole in the base structure and is fixed on the base structure through screwing of the locking nut 2, so that the ball-supporting rod and the base are firmly connected.
The reinforcing pipe and the fulcrum bar can be connected in a riveting or interference fit mode, the locking screw and the reinforcing pipe are also connected in an interference fit or riveting mode, and in this case, the axial central blind hole or through hole in the locking screw is a unthreaded hole. Preferably, however, the locking screw is connected with the reinforcing pipe in a screw fit manner so as to be convenient to disassemble, assemble and move.
The stiffening tube is preferably made of an elastic material and has a certain length, for example 1/4-1/3, which occupies the whole length of the cue and the stiffening tube which are screwed together, and the bending modulus of the stiffening tube is larger than that of the cue, so that the moving track of the ball under a certain stress is not a complete circular arc but is equivalent to the superposition of two circular arc motions, and the moving tracks under different stresses are different, thereby improving the difficulty of training.
The billiard cue is made of elastic carbon fiber materials or other materials with high hardness and high elasticity, and the rebounding speed of the table tennis ball is increased due to the fact that the billiard cue is made of the elastic carbon fiber materials, so that the billiard cue is closer to the actual practice situation, and the challenging fun of training is increased. In this case, the lower end of the cue stick preferably extends to the lower end portion of the reinforced pipe, thereby improving and improving the overall strength and resilience characteristics of the cue stick and the reinforced pipe.
The fixed cover of fixed establishment is established the upper portion of a ball arm, is equipped with two upper and lower round holes on the table tennis of exercise usefulness, fixes on the fixed establishment, fixed establishment divide into upper and lower two parts, fixed establishment's lower part is equipped with ball support 6, ball support is the ascending figure nail shape structure of point portion, and its pin fin part is the taper shape of no point, passes the lower hole of table tennis, and its nut part holds in the palm the lower part of table tennis, fixed establishment's upper portion is equipped with lock ball silk post 8, the upper hole of table tennis is passed to the lower part of lock ball silk post, the upper portion and the lock ball nut 9 of lock ball silk post pass through screw thread swivelling joint, through lock ball nut's rotation makes the table tennis fastening is in the centre of ball support and lock ball nut or dismantle and trade the ball.
The ball support and the ball support rod are fixed through riveting, or a rib or a step is arranged below the ball support on the ball support, or the ball support and the ball support rod are combined for use, or other prior art is adopted for fixed connection.
The ball locking screw column and the ball supporting rod are fixed through riveting, so that the ball locking screw column and the ball supporting rod cannot fall off under the normal stress condition, and other prior art can be adopted for fixed connection.
As an improvement, a table tennis ball can be tied on the upper end of the cue stick by using a bungee cord with certain strength without the fixing mechanism, the length of the bungee cord is proper, for example, the length of the free state is not more than 1/6-1/4 of the total length of the cue stick and the reinforcing pipe which rotate together, the maximum stretching amount in normal use is not more than 50% of the free length, the elasticity coefficient of the bungee cord can be determined according to the strength of a normal user, and the design can enable the track of the ball to be more irregular and more variable, so as to enhance the training difficulty.
The connection of the elastic rope and the corresponding table tennis can adopt any suitable mode. For example, a fixing elastic ball is arranged in a table tennis, the table tennis connecting end of an elastic rope is fixedly connected in the fixing elastic ball in the manufacturing process of the fixing elastic ball to form an integral structure, a hole is arranged on one hemisphere of the table tennis, the hole diameter is equal to or slightly larger than the outer diameter of the elastic rope and is far smaller than the diameter of the elastic ball, the elastic rope penetrates through the hole, the elastic ball is placed between the two hemispheres of the table tennis, and then the two hemispheres of the table tennis are closed and bonded to form a ball.
