The invention discloses a basketball shooting training device. The device comprises a circular truncated cone, and an annular disc is arranged on the outer side of the circular truncated cone. A sliding groove is formed in the annular disc in the radius direction of the annular disc. A sliding block is slidably connected to the sliding groove. The sliding block is connected with a supporting framethrough a swinger. A backboard is fixed to the top of the supporting frame. A basket is arranged on the side, facing the circular truncated cone, of the backboard. A vertical supporting rod is fixedon the annular disc. The vertical supporting rod is located on the extension line of the straight line where the sliding groove is located and is close to the annular disc. A longitudinal circular ring is arranged at the top of the vertical supporting rod and connected with the backboard through a conveying pipe. An electric telescopic device capable of doing reciprocating motion in the length direction of the sliding groove is arranged on the groove wall of one side of the sliding groove, and the free end of the electric telescopic device is connected to the sliding block. The basketball basket moves around a trainer, and the distance between the basket and the trainer is adjusted, so that the trainer can easily adjust the distance and the angle between the trainer and the basket and simulate shooting at each angle position.

The invention relates to an electronic mechanical padlock. The electronic mechanical padlock comprises a lock body and a lock bar. A lock bar left hole and a lock bar right hole which are vertically downward are formed in the top of the lock body in the length direction. The two ends of the lock bar are correspondingly arranged in the lock bar left hole and the lock bar right hole. The lock body internally comprises a lock cylinder. The lock cylinder comprises an inner shell. A motor is arranged in the inner shell. An output shaft of the motor is connected with a transmission cap. Lock tongues are arranged on the transmission cap. A buckle is arranged on each lock tongue. Clamping grooves are formed in the lock bar. The clamping grooves are formed in the two ends of the lock bar and engaged with the right lock tongue. The electronic mechanical padlock further comprises an electronic identification module and a LIGHTING DOCK connector. The electronic identification module is connected with the motor and the LIGHTING DOCK connector. Compared with the prior art, according to the electronic mechanical padlock, buckling plates are pulled through the motor to make the lock tongues extend and contract, the continuous opening state, namely the half-open state of the lock can be achieved, the problem that the service life is shortened due to the repeated use of the lock is avoided, switch of the half-open state and the full-open state is set by handheld equipment of a user, the structure of the electronic mechanical padlock is simple, and the production cycle is shortened greatly.
