Generally, a bowling abdomen is widely used to protect the wrist from the risk of injury by preventing the wrist from being excessively bent due to the weight of the bowling ball and correct pitching according to the rotation of the ball.

The bowling abdomen has been presented in various forms so far. In the simplest case, the wrist is fixed to prevent the wrist from being bent. In recent years, when the angle of the bowling abdomen is arbitrarily adjusted by the user, So that the rotation of spins or hooks can be adapted to their own preference.

In general, bowling ladies have begun to be used as means for preventing the wrist from being injured by heavy bowling balls. However, in recent years, they have been used as a means of creating a better pitch by making a stable wrist shape and posture.

For example, if the wrist is bent inward, the hook becomes stronger. In the case of the beginner, when the wrist is released at the moment of releasing the ball, the hook of the intended bar is not inserted. .

In addition, the left and right angles of the wrist have a significant influence on the pitch of the ball, and it is difficult to maintain a stable posture when the wrist is weak.

In order to maintain the right fingers and wrist position according to the balls, the bending angles of the upper and lower and left and right sides of the wrist are very important. For this purpose, the connecting angle between the back plate and the wrist plate can be adjusted Various types of angular adjustment devices have been proposed.

As one example of such a wrist support for bowling, there is a technique disclosed in Korean Utility Model Application No. 20-2012-0000543 as shown in Figs. 1 and 2, and its technical feature is that, in a bowling abdomen, A wrist plate frame 12 coupled to the wrist plate 10 and rotatable in the left and right direction according to the operation of the lock / unlock lever 11, And an angle regulating device 15 mounted on the wrist frame 12 to adjust the angle of the back plate 14, The angle regulating device 15 includes a case body 18 which is mounted on the upper surface of the wrist frame 12 with the upper operation hole 16 and the front entrance hole 17, Supported at both ends on a pair of support rods (19) formed inside the apparatus main body (18) The worm 20 is disposed below the inner worm 20 of the apparatus main body 18 and engages with the worm 20 and moves forward and backward by the rotation of the worm 20, And a worm bar (21) for pushing the worm bar (21).

However, although the technique described in Korean Utility Model Application No. 20-2012-0000543 can adjust the up and down and left and right angles of the wrist part, there is a problem that the left and right angles can be easily changed because the fixing force of the left and right angle adjusting parts is poor, When adjusting the angle, since the degree of the angle can be adjusted finely, it takes a lot of time to adjust the angle, which is troublesome. Also, the angle of the worm 20 can be changed during the bowling event, There is a problem.
