The invention discloses equipment for disassembling a bearing on a rotating shaft. The equipment for disassembling the bearing on the rotating shaft comprises a rack, wherein a rotating shaft cavity with a leftward opening is formed in the rack, two sliding grooves are formed in the inner wall of the upper side and the inner wall of the lower side of the rotating shaft cavity in a communication mode, and the two sliding grooves are symmetrically distributed up and down with the center of the rotating shaft cavity as the symmetric center; and abutting plates are slidably arranged in the sliding grooves. According to the invention, the bearing on the rotating shaft can be disassembled, so that the situation that when people replace the bearing, much time is consumed to disassemble the bearing on the rotating shaft, and then the replacement speed is reduced; and moreover, damage to the rotating shaft during manual disassembling by people is avoided, and the physical output of a replacement person is reduced while the replacement speed is increased.

The invention discloses a gymnastic turnover skill trainer. The trainer comprises a pedestal, wherein an annular slot with a cross section being in the shape of a swallow tail is formed in the top surface of the pedestal; a plurality of sliders with swallow-tail-shaped cross sections are arranged in the annular slot; the plurality of sliders are uniformly distributed; the bottom end of a verticalsupport rod is fixedly connected to the top surface of each slider; the top ends of the plurality of support rods are fixedly connected via a circular turn plate; a tooth ring is fixedly connected with the periphery of the circular turn plate, and the tooth ring is of an external tooth structure. According to the trainer, a turnover plate is axially turned over and can be stopped at different positions to perform decomposed explanation of turnover skills and action essentials, so that a practicer conveniently grasps the different turnover skills and action essentials, the practice difficulty of the practicer is reduced, the practice speed of the practicer is improved; meanwhile, power is provided via a first motor and a second motor, so that the practicer can perform anti-vertigo practice,output of physical power of the practicer is reduced while the practicer adapts to vertigo, and thus practice time is increased and practice efficiency is improved.

The invention provides a battery installation support for a vehicle. Installation beams are arranged on two sides of the battery installation support, installation grooves with a same extending direction are arranged in the installation beams, a plurality of rolling wheels with a same rolling direction are rotatably arranged in the installation grooves, and circumferential surfaces of the rollingwheels are higher than upper edges of the installation grooves. Swing devices corresponding to the rolling wheels in number are further arranged in the installation beams and comprise swing arms and driving mechanisms, the rolling wheels rotate at one ends of the swing arms, and the other ends of the swing arms rotate on inner walls of the two sides of the installation grooves through a rotating shaft. And each driving mechanism can drive the swing arm to rotate so as to make the circumferential surface of the rolling wheel to be lower than the upper edge of the installation groove. A batteryinstallation process is effectively simplified, an installation and positioning process is easier and convenient, and meanwhile, accurate positioning of a battery position can be ensured.

The invention discloses a high-efficiency ball picking device for badminton training and a ball picking method thereof, which belong to the field of badminton. A high-efficiency ball picking device for badminton training can simultaneously pick up multiple balls in a standing state during the badminton training process. The falling shuttlecock improves the efficiency of picking up the ball compared to picking up the ball alone. When picking up the ball, the end of the retractable rod can be in contact with the shuttlecock, so as to realize the adsorption of the shuttlecock. After picking up the shuttlecock, control the shrinkage line through the layered handle Rolled up, so that the inner retracting rod retracts toward the self-opening and closing oblique club, so that multiple magnetic isolation arcs contact each other, thereby isolating the magnetic attraction between the shuttlecock and the retracting rod, and realizes the release of the picked up shuttlecock. Attached, it is easy to pick up the ball again. Compared with the existing technology, it can effectively prevent the trainer from bending over to pick up the ball one by one, which can significantly improve the efficiency of picking up the badminton ball, and at the same time effectively reduce the unnecessary physical exertion of the trainer due to picking up the ball. , so as to effectively ensure the training effect of the trainer for badminton.

The invention relates to a portable fire-fighting equipment for gardens, which includes a casing, a handle, an oil tank, a grip rod, a first air outlet pipe, a first fixing plate, a dry powder storage box and a connecting rod. The inner side of the casing is provided with a sound-absorbing layer, the inner side of the buffer layer is provided with a fan, the handle is provided at the lower right end of the shell, and the handle is provided with a fire switch, and a discharge pipe is provided below the exhaust fan, and the discharge pipe is inserted in the second Inside the air outlet pipe, the end of the telescopic rod is connected with a support frame, and the support frame is provided with a second rotating shaft, and the lower surface of the support frame is provided with a suction cup. The interior of the portable fire extinguishing equipment for gardens is provided with a buffer layer, and a buffer spring is arranged on the buffer layer. Such an arrangement can utilize the elastic force of the buffer spring to offset the vibration feeling generated when the device is in use, and can also reduce the vibration of the user. Numbness in the palm of the hand allows for a stronger grip on the device.
