Abstract: The disclosure provides a driving assembly and a garden tool. The driving assembly includes a connecting base and a driving device. The driving device includes a driving body, a mounting part and an output shaft. The output shaft includes an input section and an output section. The input section is housed in the driving body and extends outward from the driving body to form the output section. The mounting part is arranged on a side of the driving body close to the output section, and a receiving hole is opened on the connecting base. A side of the driving body away from the output section passes through the receiving hole and connects a bottom of the connecting base with the mounting part.

Abstract: The disclosure provides a vacuum cleaning system. The vacuum cleaning system includes a vacuum cleaner and a storage device. The vacuum cleaner includes a battery pack and charging contacts. The storage device includes a vacuum cleaner holder, a bracket and a wall mounted bracket. The vacuum cleaner holder includes a first wall mounted connection structure, a first bracket connection structure and a suspension supporting structure. Two ends of the bracket are respectively provided with a bracket base, and a second bracket connection structure detachably connected with the first bracket connection structure. The wall mounted bracket is mounted on a vertical wall, and is provided with a second wall mounted connection structure detachably connected with the first wall mounted connection structure. The charging contacts are electrically connected with the storage device when the vacuum cleaner is docked with the storage device.

Abstract: The disclosure provides a string trimmer. The string trimmer includes a protective shield, a first motor, a blade and a fan. The first motor is arranged on one side of the protective shield, and a first rotation shaft of the first motor penetrates the protective shield to the other side of the protective shield. The blade is arranged on the other side of the protective shield, and the blade is connected with the first rotation shaft. The fan is arranged on the same side as the first motor, and the fan is mounted on the protective shield through a second rotation shaft. Wherein, a rotation speed ratio between the second rotation shaft and the first rotation shaft ranges from 0.5 to 4. With the string trimmer of the disclosure, the rotation speed of the blade and the fan are different.

Abstract: There is provided a composite separator for a lithium-ion battery, including a polyolefin substrate and a coating layer containing a binder and inorganic particles formed on a surface of the polyolefin substrate, a hydrogen bond being formed between the binder and the inorganic particles. Also provided are a method for preparing the composite separator for a lithium-ion battery and a lithium-ion battery using the composite separator. The composite separator of the present application increases adhesion force between the substrate and the inorganic particles, thereby reducing detachment of the inorganic particles. By using the composite separator, the product quality of the battery is improved, and the risk of influencing the safety performance of the battery caused by the detachment of the inorganic particles in a production process is reduced.
