Through the mandrel, linear motion is transformed into rotary motion and transferred to the worm, the worm wheel is driven to rotate, the opening angles of the cutter bodies are thus controlled, continuous cutting of the sleeve pipes different in diameter can be achieved, the number of times of tripping operation is reduced, and the sleeve pipe cutting efficiency and operation reliability in the operation of abandoned wells are largely improved.

The invention discloses a backpack motor-driven sprayer with a rope-pull falling-back starting function. The sprayer comprises a rack, a fan, a gasoline machine, an oil tank, a medicine box, a starter and the like; the starter comprises a starting shaft, a ratchet clutch piece, a spring seat, a starting plate, a restoration spring, a pulling rope and an outer shell, wherein one end of the shaft is a single-way ratchet wheel, and the other end is a round shaft; the ratchet clutch piece is installed on a gasoline rotor S; the spring seat and the starting plate are installed on the starting shaft; the surface of the spring seat is provided with a boss; the restoration spring is installed between the spring seat and the starting plate; the inner end of the restoration spring is connected withthe starting plate, and the outer end of the restoration spring is connected with the spring seat; the pulling rope is wound on the starting plate; one end of the pulling rope is connected with the starting plate, and the other end of the pulling rope is connected with a starting handle; the outer shell is sleeved on the starting plate; the inner side wall of the outer shell is provided with a groove which is matched with the boss; and the center of the bottom part of the outer shell is provided with a shaft sleeve which is slidingly matched. Two ends of the starting shaft of the sprayer are placed in the axial hole of the spring seat and the shaft sleeve on the outer shell, when one end of the starting shaft is pulled by the pulling rope, the starting shaft is not subjected to radial central deviation, the pulling rope can be taken back in time, and the starting is safe and reliable.

The invention discloses an intelligent indoor and outdoor clothes drying rack, which includes a telescopic device, a lifting device, a transmission device and a controller. It solves the problem of long-term single-sided exposure and uneven drying of clothes. At the same time, the telescopic device and lifting device realize the indoor and outdoor drying and lifting functions of the clothes rack; the controller uses an infrared detector to detect the state of the clothes fixed on the clothes rail, which plays a role The function of anti-loss; the controller uses the limit device to monitor the power-off time of each motor, which prolongs the service life of the motor; the controller uses the sensor component group to monitor the weather in real time, and reminds people to take the clothes rack indoors in time when abnormal weather occurs; The controller communicates wirelessly with the remote control terminal, and people use the remote control terminal to take the drying rack back into the room to solve the problem of no one collecting clothes, and closing the window solves the problem of the clothes being taken back into the room being wet and scraped away.

The invention relates to the technical field of baking, and discloses an automatic fixed pallet transport device for a baking oven, comprising a shell, the inside of the shell is fixedly connected with a support shell, the inside of the support shell is fixedly connected with lamp beads, the support shell The inner movable connection of the rotating gear is connected with the rotating gear, the outer movable connection of the rotating gear is connected with the chain, the outer part of the chain is fixedly connected with the connecting block, and the outer part of the connecting block is fixedly connected with the photosensitive component, through the interaction between all the structures of the device, it can make When the operator uses the oven, the transport tray is extended in time, which is convenient for the operator. At the same time, the cake tray can be fixed in time under the action of the push rod, and it can ensure that the surrounding of the cake is heated evenly. After the cake is removed, the tray can be retracted in time, preventing the operator from accidentally touching the tray and causing burns, ensuring the safety of the operator and improving work efficiency.

The invention relates to the technical field of awnings, and discloses a new energy awning that can be automatically opened under heavy rain, including a vertical plate, and a tooth bar is connected to the front wall and the left wall of the vertical plate in rotation. The upper part of the plate is fixedly sleeved with a supporting plate, the upper end of the left part of the supporting plate is provided with a storage battery, the upper end of the storage battery is provided with a driving device, a driving shaft is provided between the driving device and the gear bar, and the inner cavity of the driving shaft is provided with The through groove, the right part of the inner cavity of the through groove is provided with a spring tube, and the inner cavity of the spring tube is provided with a nanometer material.
