DETAILED DESCRIPTION

[0023] A hole adjustment device includes a slope plate 1 for a golf practice device. The slope plate 1 is a component of the golf practice device. The slope plate 1 is made of plastic. The front of the slope plate 1 is a slope practice surface 11. A lower ball hole 12 is provided in the middle and rear part of the slope practice surface 11 (the opening of the lower ball hole 12 is the hole of the hole). The lower ball hole 12 is circular. The diameter of the lower ball hole 12 is fixed, generally ranging from 5 cm to 12 cm, and can be set according to actual needs. The left, right, and rear edges of the slope plate 1 are upward. A frame 13 extends from the ramp board 1, allowing the ball to roll uphill only from the front end onto the sloped practice surface 11. The frame 13 prevents the ball from rolling out to the left or right side. If the ball does not roll into the hole after rolling uphill, it can flow back through the sloped practice surface 11. The back side of the ramp board 1 is connected to an orifice adjustment device 2 for adjusting the size of the lower ball hole 12. The orifice adjustment device 2 is not limited to the specific structure described below. The orifice adjustment device 2 adjusts the diameter of the lower ball hole 12 to a degree that does not decrease below the diameter of the golf ball being practiced. For example, if a golf ball has a diameter of 42 mm and weighs 46 grams, and the diameter of the lower ball hole 12 is 10 cm, the orifice adjustment device 2 adjusts the diameter of the lower ball hole 12 to 45 mm, which is larger than the 42 mm diameter of the golf ball. In other words, the orifice adjustment device 2 can adjust the diameter of the lower ball hole 12 to between 100 mm and 42 mm.
