Description

Technical Field

[0001] The utility model belongs to the technical field of lithium-electric scissors, in particular to a pair of lithium-electric scissors. Background Art

[0002] Lithium-ion battery scissors are compact and portable, making them a common tool for gardening. They typically include a movable blade and a fixed blade. The fixed blade is fixedly mounted on the housing, while the movable blade is rotatably connected to the fixed blade. The movable blade is driven by a motor through a transmission mechanism to swing back and forth, thereby performing the shearing action. Currently, lithium-ion battery scissors are typically designed with the motor mounted inside the handle. However, this design presents a significant problem: the motor generates a large amount of heat during operation. Because the motor is closely attached to the handle, this heat is directly transferred to the operator's hand, causing hand discomfort. When using these lithium-ion battery scissors for extended periods, the operator may find the constant heat accumulation unbearable, thus affecting work efficiency and comfort. Furthermore, the motors of current lithium-ion battery scissors are mostly arranged vertically, which increases the height of the device. Furthermore, since the length and width of the motor also occupy a certain amount of space, the overall volume and length of the device are also increased accordingly. This may impose certain restrictions on the installation and use of the device, especially in environments with limited space. Therefore, during design and layout, the impact of this vertical arrangement on the overall device size needs to be fully considered to ensure that the device can operate normally within the intended space.
