On the other hand, Figure 6 is another embodiment of the putting practice, to install a rather thin flat green portion 210 a predetermined length from one side of the hole cup body 110 to the putting position, wherein the thickness of the green portion 210 As the relative height of the hole cup body 110 is lowered, the same conditions as in the actual green are given.

The on / off cam 150 and the actuating cam 170 installed on the driving motor 130, the reduction gear unit 140, and the drive shaft 144 are installed on the hole cup main body 110, and the operating plate ( After the 180 is embedded in a separate case, even if the case is installed at a position close to the hole cup main body 110, it belongs to the scope of the present invention.

Hereinafter, the operation of the putting practice configured as described above are as follows.

First, the putting exerciser is installed at an appropriate position, and then the putting position is taken at a predetermined distance. At this time, a somewhat thin flat green portion 210 may be installed between the putting position and the putting exerciser.

In addition, the insertion hole 114 of the ball guide 113 is inserted into the fixing hole 112 formed at the rear of the hole cup 111 of the hole cup body 110 to pass the hole cup 111 or slightly biased the golf ball 300. ) Into the hole cup 111.

When the putting exerciser is installed as described above, the golf ball is putt in the putting position. When the golf ball 300 is introduced into the hole cup 111, the golf ball 300 is inside the hole cup 111 as shown in FIG. 5B. It is located in the ball holder 191 of the operating table 190 is installed and at the same time to operate the push switch 200 installed on the bottom of the hole cup 111.

The push switch 200 detects this for a predetermined time, for example, for one second as shown in FIG. 7, and then operates the driving motor 130. At this time, the rotational force generated from the driving motor 130 is reduced in number of the reduction gear unit 140. In the process of rotating the drive shaft 144 by one gear (141, 142, 143) of the fan-shaped on / off cam 150 fixed to the drive shaft 144 starts to rotate at the same time to turn off the power cut-off switch 160 of one side Will remain on.

On the other hand, the drive motor 130, and the reduction gear 140 is rotated by the rotational force is very low, so that almost no mechanical noise occurs.

At the same time, the operation cam 170 at the end of the drive shaft 144 rotates together to lift the projection 181 on one side of the operation plate 180 as shown in FIG. 5A, wherein the ball holder (fixed to the operation plate 180) 191 is a moving magnet 196 fixed to one side is attached to the fixed magnet 198 of the hole cup 111 and the magnetic force, so that the driving force generated by the driving motor 130 is a moving magnet of the ball holder 191 ( When the driving force is generated after about 2 seconds 196 is separated from the stator magnet 198 of the hole cup 111, the moving magnet 196 is separated from the stator magnet 198 and the golf ball 300 is seated ball holder An operating table 190 having 191 lifts the support shaft 193 into the shaft.

As the operating plate 180 rotates, the operating plate 190 connected to the operating plate 180 is rotated so that the inclination of the operating plate 190 is about 60 degrees to the ball holder 191 of the operating table 190. The golf ball 300 that was placed is to be rolled from the operating table 190 to the putting position.

When the inclination of the operating table 190 is about 60 degrees, the operating cam 170 is separated from the protrusion 181 on one side of the operating plate 180 corresponding to the operating cam 170, and at this time, the operating table 190 as shown in FIG. 5B. Owing to its own weight and the restoring force of the return spring 194 formed on one side of the support shaft 193, the operating table 102 quickly returns to the bottom surface of the hole cup 111.

At this time, the movable magnet 196 of the operating table 190, the ball holder 191 to the fixed magnet 198 of the hole cup is not generated any noise due to the rubber film 197 surrounding the outer periphery.

At the same time, the fan-shaped on / off cam 150 is released from the power cutoff switch 160 and at the same time, the power supplied to the driving motor 130 is turned off, and at this time, the predetermined angle is rotated by the rotational force of the driving motor 130. The on / off cam 150 is maintained in its original position.

Therefore, the present invention eliminates the green portion and lowers the height of the hole cup to almost the same height as the green, thereby creating a condition similar to that of the general green, while increasing the return force of the golf ball regardless of the number of times of use, and automatically returning to the putting position as well. In addition, there is a very useful effect that allows the user to concentrate only on putting practice by eliminating noise during automatic return of the golf ball.
