Abstract[English]
An electric tool (100), comprising an adjustment sleeve (4), wherein the adjustment sleeve (4) has a first arm of force (41), by means of which a transmission arm (311) is driven to rotate and a mode switching member (31) is moved from a first position to a second position; the adjustment sleeve (4) further has a second arm of force (42); when the mode switching member (31) is maintained at the first position, the transmission arm (311) and the second arm of force (42) are misaligned in an axial direction, such that when the adjustment sleeve (4) rotates, the second arm of force (42) cannot come into contact with the transmission arm (311); and when the mode switching member (31) is maintained at the second position, the transmission arm (311) moves to axially overlap with the second arm of force (42), such that when the adjustment sleeve (4) is rotated in a direction opposite a first direction, the second arm of force (42) drives the mode switching member (31) to rotate, thereby preventing a torsion spring (34) from not being able to get the mode switching member (31) of the electric tool (100) reset due to excessive circumferential resistance, and thus ensuring that the electric tool (100) can be smoothly switched from an impact gear back to a drilling gear.[French]
L'invention concerne un outil électrique (100), comprenant un manchon d'ajustement (4), le manchon d'ajustement (4) présentant un premier bras de force (41), au moyen duquel un bras de transmission (311) est entraîné en rotation et un élément de commutation de mode (31) est déplacé d'une première position à une seconde position ; le manchon d'ajustement (4) présente en outre un second bras de force (42) ; lorsque l'élément de commutation de mode (31) est maintenu dans la première position, le bras de transmission (311) et le second bras de force (42) sont désalignés dans une direction axiale, de sorte que lorsque le manchon d'ajustement (4) tourne, le second bras de force (42) ne peut pas entrer en contact avec le bras de transmission (311) ; et lorsque l'élément de commutation de mode (31) est maintenu dans la seconde position, le bras de transmission (311) se déplace pour chevaucher axialement le second bras de force (42), de sorte que lorsque le manchon d'ajustement (4) est en rotation dans un sens opposé à une premier sens, le second bras de force (42) entraîne l'élément de commutation de mode (31) en rotation, évitant ainsi qu'un ressort de torsion (34) ne puisse pas réinitialiser l'élément de commutation de mode (31) de l'outil électrique (100) en raison d'une résistance circonférentielle excessive, et garantissant ainsi que l'outil électrique (100) puisse être commuté en douceur d'un mode percussion à un mode perçage.[Chinese]
一种电动工具（100），包括调节套（4），调节套（4）具有第一力臂（41），第一力臂（41）带动传动臂（311）旋转并将模式切换件（31）由第一位置移动至第二位置；调节套（4）还具有第二力臂（42）；模式切换件（31）保持于第一位置时，传动臂（311）与第二力臂（42）沿轴向方向错位，调节套（4）旋转时，第二力臂（42）无法接触传动臂（311）；模式切换件（31）保持于第二位置时，传动臂（311）移动至与第二力臂（42）轴向重叠，沿与第一方向相反的方向转动调节套（4），第二力臂（42）带动模式切换件（31）转动，避免电动工具（100）的模式切换机构（31）因周向阻力过大而使扭簧（34）无法将模式切换件（31）复位，确保电动工具（100）可以顺利由冲击档切换回钻档。
