The palm curved device 12 includes a bottom portion 122, a slope portion 124 and a comfort portion 126; wherein the bottom portion protrudes from the ball striking panel; the bottom portion of the inclined portion is connected to the bottom portion, and the top end is farther from the bottom than the bottom portion On the reverse side, the side of the center of the opposite side of the ball hitting the racquet face is inclined at about 37 degrees; the comfort part is placed on the side of the front surface of the near ball at the top end of the inclined portion. The bottom layer portion 122 of the palm-shaped arc-shaped device 12 is a cylinder, and the bottom surface 1220 connected to the racket is a flat surface, and the top surface 1222 opposite to the inclined portion is a sloped surface, which is 38 with the racket hitting surface. The angle of the corner is oblique to the center axis of the racket at an angle of 45 degrees. Its long axis length and the maximum height of the slope are about the hand center position P1 when the backhand grip is taken. The inclined portion 124 is a smooth elliptical cylinder slightly smaller than the bottom portion adapted to the palm of the hand, and the inclined portion is closer to the center of the opposite side and the inclination angle of the bottom surface is 50 degrees. The two sides of the short axis are plane, and the bottom portion 1240 is connected to the inclined top surface 1222 of the bottom portion; the comfort portion 126 is disposed on the short-axis side surface of the inclined portion near the front surface of the ball, which is a cylindrical body with a curved surface.

The quick-change device 14 is a triangular cylinder disposed on the hand-held connecting portion on the opposite side of the ball striking, and the inclined surface of the bottom portion of the arc-shaped arc-shaped device is close to the side of the racket surface, and protrudes from the racket hitting surface. The vertical plane connecting the top plane of the top surface and the edge of the near hand-held connecting portion is a smooth arc narrow surface 142, and the smooth narrow surface long axis is inclined at an angle of 59 degrees with respect to the central axis of the racket surface, as shown in FIG. 5, that is, by the board surface Rotate clockwise approximately 59 degrees. The multi-function device 16 is a cylinder whose bottom is connected with the hand-held connecting portion of the front surface of the ball, and the top portion 162 is a circular arc surface; the multi-functional device is opposite to the bottom surface of the bottom portion of the arc-shaped device of the hand. The inclination angle is about 65, as shown in Fig. 5: the long axis of the bottom layer is rotated clockwise by about 45 degrees from the axial direction of the plate surface, and the long axis of the multi-function device is rotated counterclockwise by about 65 degrees from the long side of the bottom surface of the bottom portion. The multi-function device is inclined to be opposite to the direction in which the bottom portion of the opposite side of the ball is inclined. Referring to FIG. 5, the long axis of both the multi-function device and the bottom portion is rotated counterclockwise by 20 degrees from the central axis of the plate surface, respectively. It is about 45 degrees clockwise, and can also be inclined in the opposite direction to the bottom portion on the opposite side of the ball striking and at an angle to the ball striking surface. The palm-arc device, the quick-change device and the multi-function device can be fixed by an adhesive connection. .

Specifically, the shape and size of the racket can be ergonomically designed, and the size of the palm curved device 12, the quick change device 14, and the multi-function device 16 of the handle portion are changed according to the size of the human hand. Figure 12 shows the palm of the right hand of the person, P1 is the palm of the hand, P2 is the upper palm range below the thumb, P3 is the lower palm range below P2, and P4 is the joint position connecting the thumb and palm. F1 is the first quarter of the middle finger and F2 is the second section of the middle finger. The palm-shaped orphan device makes the positive and negative hand grip postures stable and easy; the inclined portion makes it difficult for the finger and the finger holding it to block the ball. It also allows the middle finger, ring finger and little finger to hold the handle firmly and comfortably during the back and back grip. Because there is a sloping part, so The small thumb, ring finger and middle finger are easy to hold and the fingers and the inclined part are not easy to block the ball; the foot can be effectively, stably and comfortably pressed in the comfort part and the comfort part can be prevented from opening or blocking the palm of the hand. The inclined portion is connected to the backboard surface via the bottom portion. If the bottom part is missing, the backhand grip method will not be implemented; if the inclined part moves to the board surface in a vertical way with the board surface, the ring finger and the little finger cannot have enough length to firmly grasp the inclined part, if The inclined part moves to the board surface by its own long axis, and the bottom part of the inclined part of the near board will open or block the palm of the hand. If the inclined part moves to the board in other directions, the above two problems are all Will appear. The bottom layer portion causes the palm-shaped curved device to extend away from the palm of the hand, and the inclined portion is stabilized and easily grasped by the fingers.

The backhand and forehand gripping methods are shown in Figures 13 through 16, respectively. The positive and negative hand grip positions can be speeded and easily converted to each other; the racket is designed to allow the user to control, change, and maintain the position and orientation of the racket with the fingers and palm of the clapping hands. This advantage is to reduce the movement of the user's footsteps, the swinging and turning of the waist, and make the returning ball faster, easier, more accurate and less laborious. The racket is also designed to allow the user to change the position and orientation of the racket using gravity. If you want to move from the backhand grip position to the forehand grip position, the user only needs to relax the palm, the racket will quickly drop to the proper position, and the racket is designed as the upper palm of the palm. The range P2 is pressed in the handle in the forehand grip position. The comfort part, while the lower palm range P3 is pressed against the comfort part of the handle in the backhand grip position, because the center of gravity of the racket is higher than the forehand when preparing for the backhand; this is also labor-saving. The upper palm range P2 is pressed against the multi-function device of the handle in the backhand grip posture, and the thumb is pressed on the multi-function device in the forehand grip posture. In the backhand grip position, the palm of the hand is located on both sides of the board, pressing on different parts of the handle, the middle finger, the ring finger and the little finger are pressed against the arc of the hand, and the finger is pressed against the center of the front panel. In the forehand grip position, the palm of the hand is on the backhand panel and only presses the handle on the backhand panel. The upper palm range P2 is pressed against the comfort part of the handle. The middle finger, ring finger and little finger are pressed against the curved arc of the hand, and the thumb is pressed against the multi-function device, instead of the plate surface, the index finger is controlled against the center of the backhand plate. The advantages of this positive and negative hand grip posture are: The female finger presses on the center of the forehand board surface, it is easy to force the backhand ball, and the index finger controls the center of the backhand board surface, which is easy to force and correct. Handball. When playing back and backhand, the attack face is easy to face forward, up or down. The curved surface and the large area of the comfort part make the palm part of the palm part range P2, and the lower palm area P3 can be pressed firmly and comfortably, so that the positive and negative grips are stable. The first or second section of the middle finger: The F1 or F2 press pushes the arc surface of the quick change device or its top plane, and pushes the multi-function device with the thumb press, which can be quickly and easily changed from the forehand grip to the backhand. The corners and sides of the quick change device are rounded to avoid scratching your fingers. The multi-function device has other functions. When the backhand grip is held, the palm part of the palm is pressed against the palm of the hand. P2 can stabilize the racket. If it lacks the angle formed by the forearm and the board surface, the angle will be increased from the player's body to the approximate amount. 180 degrees, that is, if there is no bending of the wrist, the board surface is in line with the forearm, so that when the backhand is hit, the board surface is more difficult to face the front, reducing the power of the diagonal line. When the palm part of the lower palm range P3 is pressed in the comfort part, it helps to control and stabilize. When the palm portion P2 of the palm portion is pressed against the multi-function device, the joint P4 can be prevented from being uncomfortably held against the edge of the blade. In addition, before playing the handball, the body can be straight (the rubber is on the handle) as a preparation action, and the thumb is pressed to push the multi-function device so that the body is horizontal (the rubber and the handle are at the same height). When the backhand grips the shot, the angle of returning the ball changes greatly. When the forehand grips the ball, the surface of the board is easily facing the front without bending the wrist, reducing the movement of the foot and the rotation of the waist. At the same time, since a large part of the handle part is vertically projected on the surface of the hitting board, this makes the hitting board surface not hold the palm of the hand when the backhand grip is held, and does not put the palm and the thumb when holding the forehand. In addition, the vertical projection of some multi-function devices can be used outside the board to reduce the weight of the board. The bottom part is provided with a groove at one end of the body, and the forefinger is placed for the back grip. The inclined portion is from the top to the bottom, and a groove may be provided to enable the finger to securely catch it.

Of course, in order to make the bottom part more securely attached to the board, screws can be added in addition to the glue; in order to make the comfort part firmly connected to the inclined part, an additional connection part can be added.

Of course, the rapid transition means of the handle portion of the inventive table tennis or similar hand-operated racquet can be another column of any shape with a top plane adapted to the height of the finger, which can also be connected to the underlying portion. The comfort portion of the handle portion can also be a regular cylinder or a cylinder with rounded corners, chamfers or a table or other cube with a smooth surface.

The multi-function device may also be a long axis of the inclined portion of the opposite hand-free device. The vertical projection of the board surface is inclined, and is not only inclined with respect to the center axis of the racket surface, but also may be inclined with the board surface. It may also be a protrusion with a rounded corner and a smooth surface connected to the front surface of the racket hitting ball. Any shape.

In addition, the left-hand idiom of the invention is only a mirror image of the right-hand occupant.
