New Plastic Description·· [New Technology Field] This creation is a pitching exerciser, especially a kind of pitcher for the pitcher. & handcuffs and wrist force [previous technique] In the baseball game, the pitcher's silk mosquitoes spread the results. Good game process, and make the team easy to win. For the training of the pitchers, the team is also very important for the training of the ball. ^ The quantity should not be too much, the money arm is too recorded, and the pitcher of the pitcher 2 is determined to be officially turned. In addition to the body movements, it also includes the action of the arm of the fish, the movement of the wrist, and the pitcher will finish when practicing. All the actions mentioned above. Yan Liang: = Ball action, which can make the baseball track close to or the same as the pitcher's expectations. : : In the pitching action, when some of the movements are not good, it will be : :=: The number of balls to be cast must be stopped. 2 The practice of wrist and finger is not enough, and it will affect the performance of the official pitching. • When you are a pitcher, you must instruct the pitcher to know how to hold the ball in various ways. Because there is no proper exercise tool for the pitcher to practice holding the ball and handcuffs, and 'there is no exercise tool to let the pitcher observe the rotation of the ball to reduce the learning effect.状心心仵 新型 [New Content] 5 M338679 The main purpose of this creation is to provide a pitcher exerciser that allows the pitcher to change the direction of the wrist movements. The purpose of the creation of the wristwatch is to provide a kind of pitcher exerciser, which allows the pitcher to practice • throwing the ball in the direction of the ball's defeat, and let the pitcher become more accustomed to the various goals of the ball. In the provision of a kind of silk-throwing Sii, it allows the pitcher to see the spin-off state, and makes it easier for the pitcher to understand the trajectory of various paths. The "Pitching Trainer" provided by the present invention includes a baseball and a baseball system attached to the front end of the bracket device and can be tilted on the bracket device. The hand and the wrist can be used when practicing the pitching. Action to make the baseball spin. This is the "following fll" provided by this creation. The baseball is a standard ball for the general game, and the record is recorded to the center of the ball and extends obliquely. This support is mainly in the promotion of _ baseball - continued _. The core includes a front end sleeve-sleeve provided with a body, and the sleeve can rotate the shaft as an axis. The sleeve is 靡 棒 棒 , , , 蝴 蝴 蝴 蝴 蝴 蝴 蝴 蝴 蝴 蝴 蝴 蝴 蝴_[Embodiment] Applicants think that when the pitcher throws the ball, the movement of the fingers and wrists is very important, and it is a research and development exercise, let the pitcher _ finger, hand __. I cite the examples and cooperate with _, ah, the creation of the ship and the efficacy. The present invention discloses a pitching exerciser comprising: - a baseball 10 and a bracket device 20. The miscellaneous ball 10 is coupled to the front end of the bracket device 2 and is rotatable on the bracket device 6 M338679 20. Among them, the standard ball used in the baseball 4 4-game is the same as when the pitcher holds the ball. The baseball 1G can be drilled - aperture u. The aperture u is oriented toward the center of the sphere and extends in a straight line. The stent device 20 primarily provides support to the baseball 10. In the present embodiment, the bracket device 20 is formed by appropriately bending a metal wire. The front end of the bracket device is a rod body 21, and the front end of the rod body 21 is sleeved with a sleeve 22, and the sleeve body can rotate with the rod body 21 as an axis. The sleeve 22 is placed in the aperture η of the baseball 1 ,, and the sleeve 22 _ is closed with the wall of the aperture Π. Then, the rod can rotate the shaft 21 as an axis. The county is provided with a 20-end-grip 23 for the rider to place the 23 series under the baseball 1G and in an upright position. Then the maker (right hand to the left hand can hold the training 23, is expected to hold the baseball 10, and in the face of the pitching side ten with the fingers and side action to make the baseball 丨 _. So, the ball pitching action, and the direction of the wrist rotation And the purpose of Dashunzheng finger and wrist movement is: in the 'the bracket device 2. The outer wall surface of the coffee is set with the axis sleeve 22 to rotate the baseball 1G_n^, so that = ^ forms a ruin. Object, #_ The ruthenium phase = sleeve 22, the miscellaneous sleeve 22 cannot be rotated, and then the baseball 1() is rotated and the thinness is rotated to cause the _ to be screwed into the outer wall surface of the point sleeve 22 and the wall surface of the aperture 11 provided by the baseball. In the meantime, the adhesive can be bonded to make the combination of the two more tight. By the 7 M338679, the front end rod 21 of the bracket device 2G is provided with two annular grooves %, 25, and two C-shaped buckles. 26, 27 is snapped in. The sleeve 22 is disposed between the two c-shaped clasps = 27, so that the sleeve 22 is not released by the rod body 21. In addition, the c-shaped clasp is % Between the .27 and the ends of the sleeve 22, spacers 28, 29 may be disposed, so that the baseball 1 () screw sleeve 22 does not directly hit the c-shaped buckles 26, 27. [• There are at least a kind of ball-handling method for baseball 10 spherical edge, and _ a few hands control the ball-holding method. This technical idea is a well-known knowledge, and the characteristics of the application, so it is not described. In summary, the pendulum training provided by this creation has its structure and easy operation. $Hand can use this creation to practice pitching, and practice the finger movement and wrist movement to make the pitcher's skill more refined.
