Fixed handle is connected on the handle of tennis racket lower end, interlocking has display screen on handle, and handle, at its lower end passes through screw
It is fixed with lithium battery.
Further, it is embedded with charge port on the lithium battery, is linked with switch button on lithium battery；Lithium battery passes through conducting wire
Connect pressure sensor, display screen, lithium battery, single-chip microcontroller, counter, display screen, bluetooth connector.
Further, surrounding is clamped there are four pressure sensor between the fixed iron ring and racket face, pressure sensor
Measurement end is intertwined and connected with the cable on racket face.
Further, the pressure sensor passes through conducting wire and connect with single-chip microcontroller, counter, and single-chip microcontroller passes through with counter
Conducting wire connects display screen, and display screen connects bluetooth connector by conducting wire.
The advantages of the utility model and good effect are as follows:
The utility model detects the pulling force of spherical surface cable by pressure sensor, cooperates calculating and the counter of single-chip microcontroller
Record, can cue power recorded with number of batting, and shown by display screen, bluetooth connection electronic equipment can also be passed through
It is recorded；Fixed handle can further fix the both hands of trainer, and can prevent trainer from holding loosely leads to tennis racket
The case where flying out.
The utility model can record cue power and batting number, and be shown by display screen, can also pass through
Bluetooth connection electronic equipment is recorded, and fixed handle can prevent trainer from holding the case where loosely tennis racket being caused to fly out.
Detailed description of the invention
