Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

This embodiment is not intended to limit the scope of the invention, but is presented by way of example only.

Body 10 of the present invention is a hollow pipe-shaped metal material in the upper end in Figure 1, the grip 11 for the user to hold by hand is mounted on the outside.

The grip 11 is fitted to the outside of the front end of the body 10 by a soft synthetic resin material or rubber material so that the user has a texture similar to that of holding the grip of the golf club.

Inside the body 10 in which the grip 11 is installed, a power supply unit 80 for displaying a swing speed and the like using the amount of impact of the laser pointer 90 and the speed sensor 60, which will be described later, is displayed on the display screen 70. do.

The power supply unit 80 is composed of a plurality of batteries 81, the cap bolt 85 is screwed to the front end of the body 10 for replacement of the battery 81.

Then, the guide member 20 is fixedly installed inside the upper and end portions of the hollow tubular body 10 concentrically.

In order to install the guide member 20, as shown in the drawing, the nut body 21 is fastened to the center of the upper body of the guide member 20 by screwing in the center, and several pins 22 are provided at the bottom. It is fixed to the body concentric with the body (10).

Inside the end of the body 10, the shock absorbing member 30 is made of a material of good cushioning, such as a rubber is located, even if the weight member 40 is in strong contact with the compression spring 50 by a swing, the impact The torso 10 is buffered so that the impact force is not transmitted to the user's hand.

The weight member 40 fitted between the inner diameter of the body 10 of the structure and the outer diameter of the guide member 20 may be formed by the centrifugal force during the fast swing, such as when the driver strikes the driver strongly with a metal material. Molding is relatively long in the longitudinal direction to have an appropriate weight that can be moved toward.

Both ends of the outer diameter of the weight member 40 are provided with a slide bearing 41 to minimize the resistance when the slide slides in contact with the inner diameter of the body 10, the fitting hole 42 is fitted to the guide member 20 The receiving groove 43 is dug to a larger diameter so that the end of the coil-shaped compression spring 50 can be accommodated.

The compression spring 50 is interposed between the buffer member 30 and the weight member 40, the weight member 40 is in the normal position toward the grip 11 in the free state in which the inertia does not act on the weight member 40 When the user grasps the grip 11 and the centrifugal force is applied by the fast swing is compressed.

At this time, the compression spring 50 should be designed so that the depth of the receiving groove 43 is deeper than the length of the spring at the time of compression so that the end of the weight member 40 can hit the buffer member 30 in the state of the maximum compression. .

In addition, a speed sensor 60 is installed around the buffer member 30.

That is, as shown in FIG. 4, the coil 61 is wound around the buffer member 30 in the cap-shaped speed sensor 60, and the permanent magnet 62 is formed at the end of the weight member 40. To measure the amount of current generated when the permanent magnet 62 passes through the coil 61 immediately before the impact of the buffer member 30, and to display the current amount on the display screen 70 in proportion to the current amount. An example is shown.

And, in addition to the method of the induced current by the coil 61 and the permanent magnet 62, by installing an impact sensor (not shown) on the upper portion of the buffer sensor 30, the weight member 40 by the user's fast swing After the movement, the degree of impact generated when contacting the impact sensor is detected, and it may be designed to display the numerical value on the display screen 70 through an electronic circuit.

Here, the impact amount is centrifugal force is applied in proportion to the swing speed, so it may be applied to the swing speed value in proportion to the magnitude of the impact amount.

The display screen 70 is installed so as to be exposed to the outside immediately below the grip 11, as shown in the figure so that the user can grasp numerically the amount of impact that appears in proportion to the swing speed.

In addition, a laser pointer 90 is installed inside the end of the body 10 to emit a laser beam, and the laser beam is fired through a through hole 62 drilled in the holder 91 so that the user grasps the grip 11. When swinging the body (10) is to allow the naked eye to grasp the swing angle or trajectory of the body (10).

Here, the laser pointer 90 and the display screen 70 may be selectively turned on / off by the operation of the switch 71.

In addition, the laser pointer 90 is also installed at the position of the cap bolt 85 overlapped to the upper end of the body 10 in which the grip 11 is installed, and as a through hole 86 drilled in the center of the cap bolt 85. Allow the laser beam to be fired.

Therefore, when the user swings the torso 10 while holding the grip 11, the laser beams are emitted from the tip and the tip, respectively, so that both trajectories can be identified.

The guide member 20 may be selected as a hollow pipe member to reduce the overall weight and to allow an electric wire for a circuit configuration to pass therethrough.

In this way, the grip 11 holding the golf club by hand and the swing angle or the trajectory of the end corresponding to the head can be grasped, respectively, so that the wrong part can be corrected.

And, when swinging the body 10 of the present invention by the centrifugal force, the weight member 40 overcomes the elastic resistance of the compression spring 50, while compressing and gives a strong impact at the moment of contact with the buffer member 30.

This state is used as a driver to recognize the moment when the head hits the golf ball to practice the swing.

After the quick swing operation, the weight member 40 is returned to the normal position again without any other manipulation by the elastic force of the compression spring 50, thereby preparing to immediately perform the next swing.

In this way, the swing sense and laser beam can be used to continue swing practice while adjusting the swing angle or form, and serve as a measuring device that indicates the correct swing.
