Title (EN) SCREWDRIVER
(FR) TOURNEVIS
(ZH) 一种螺丝刀
Abstract:
(EN) A screwdriver, comprising a shaft (2) and a handle body (1). A circular protruding ring (12) is provided at the front extremity of the handle body (1). A locking mechanism is provided between the circular protruding ring (12) and the shaft (2). A rotating cover (3) for unlocking the locking mechanism is sleeved on the circular protruding ring (12). The locking mechanism comprises an engaging fitting (4) and an engaging spring (5). An annular section groove (122) is provided at a side of the circular protruding ring (12). The engaging fitting (4) is provided within the annular section groove (122) and can rotate along the annular section groove (122). A grooved engaging position (211) is provided on the exterior of the shaft (2). The screwdriver is structurally reasonable, the shaft (2) and the handle body (1) are firmly connected; tightening force is great, reaches up to 500 N, and complies with European standards; operation is effortless; and, rapid removal and replacement of the shaft can be implemented. In addition, the overall size is reduced when the shaft (2) is removed, thus facilitating packaging and storage.
(FR) L'invention concerne un tournevis, comprenant un arbre (2) et un corps de poignée (1). Un anneau en saillie circulaire (12) est disposé au niveau de l'extrémité avant du corps de poignée (1). Un mécanisme de verrouillage est disposé entre l'anneau en saillie circulaire (12) et l'arbre (2). Un couvercle rotatif (3) destiné à déverrouiller le mécanisme de verrouillage est emmanché sur l'anneau en saillie circulaire (12). Le mécanisme de verrouillage comprend un raccord de mise en prise (4) et un ressort de mise en prise (5). Une rainure de section annulaire (122) est disposée sur un côté de l'anneau en saillie circulaire (12). Le raccord de mise en prise (4) est disposé au sein de la rainure de section annulaire (122) et peut tourner le long de la rainure de section annulaire (122). Une position de mise en prise rainurée (211) est disposée sur l'extérieur de l'arbre (2). Le tournevis est structurellement raisonnable, l'arbre (2) et le corps de poignée (1) sont fermement reliés; la force de serrage est importante, atteint jusqu'à 500 N et est conforme aux normes européennes; l'actionnement est sans effort; et, un retrait et un remplacement rapides de l'arbre peuvent être mis en œuvre. De plus, la taille globale est réduite lorsque l'arbre (2) est retiré, facilitant ainsi l'emballage et le stockage.
(ZH) 一种螺丝刀,包括刀杆(2)和手柄体(1),手柄体(1)前端设有圆形凸环(12),在圆形凸环(12)与刀杆(2)之间设有锁定机构,圆形凸环(12)上套设有对锁定机构进行解锁的旋转盖(3),锁定机构包括卡扣(4)和卡扣弹簧(5),圆形凸环(12)的侧部设有环段槽(122),卡扣(4)设置在环段槽(122)内并可沿环段槽(122)转动,刀杆(2)外侧设有凹槽卡位(211)。该螺丝刀结构合理,刀杆(2)与手柄体(1)连接牢固,锁紧力大,可达到500N,符合欧洲标准,操作省力,可实现刀杆(2)的快速拆卸及更换。另外,刀杆(2)拆卸后使得整体体积缩小,利于包装及储藏。
