Abstract: This disclosure discloses a high-energy power generation device for casual shoes, comprising a battery, a motor, a worm, a forward transmission crown gear, a transmission gear set, a backward transmission crown gear and a planetary gear set. This disclosure provides an efficient high-energy power generation device, which is concise in structure and exquisite in design. By the transmission design of the forward transmission crown gear, the transmission gear set, the backward transmission crown gear and the planetary gear set, this disclosure can generate power when the feet are pedaled down or lifted up, and power generation efficiency is doubled totally.

Abstract: A photoelectric sensing instant display type golf swing collimation trainer comprises a base (1) and a display device (2), two photoelectric sensor mounting supports (3, 3?) are mounted on the base (1), two groups of photoelectric detection devices with transmitters (4) and sensors (5) are mounted on each mounting support (3 or 3?), the distance between the two sensors (5) on each mounting support is matched with the distance of the straight line section at the bottom of a club head of a golf club, when the club head of the golf club passes between the transmitters (4) and the sensors (5), the pulse receiving of the sensors (5) is blocked, and the sensors (5) are used for sending the synchronous state of blocking the pulse receiving of the club head of the golf club to the display device (2) which is electrically connected with the sensors (5) for real-time display.
