The present invention discloses a tool (100) having a work implement (102), a handle (104), and a locking element (132) for detachably coupling the work implement (102) to the handle (104). The work implement (102) has an annular groove (106) disposed about a longitudinal axis (XX’) thereof. The locking element (132) is received within a hollow interior region (116) of the handle (104). The locking element (132) has a recess (144) bound by an arcuate edge (146) disposed partway along an outer circumference (C3) of the locking element (132). The arcuate edge (146) comprises a leading end (148), a trailing end (150), and a detent (152) located between the leading end (148) and the trailing end (150). The locking element (132) is rotatably moveable within the hollow interior region (116) about a transverse axis (ZZ’) of the handle (104) between an open position (P1) and a locked position (P2). When disposed in the open position (P1), the locking element (132) allows an axial movement of the work implement (102) with respect to the handle (104). When disposed in the locked position (P2), the detent (152) of the locking element (132) biases the work implement (102) towards the trailing end (150) of the arcuate edge (146) such that the detent (152) abuts with the annular groove (106) of the work implement (102) to restrict an axial movement of the work implement (102) in relation to the handle (104).本發明揭露一種工具(100),具有操作器具(102)、把手(104)、及用以將操作器具(102)可拆卸地耦接到把手(104)的鎖定元件(132)。操作器具(102)具有圍繞其縱軸線(XX’)設置的環形槽。鎖定元件(132)收納在把手(104)的中空內部區域(116)內。鎖定元件(132)具有由設置在沿鎖定元件(132)的外圓周(C3)中間部位的弧形邊緣(146)限制的凹槽(144)。弧形邊緣(146)包括前端(148)、尾端(150)及位於前端(148)與尾端(150)之間的卡爪(152)。鎖定元件(132)能在解鎖位置(P1)與鎖定位置(P2)之間圍繞把手(104)的橫軸線(ZZ’)在中空內部區域(116)內可旋轉地移動。當設置在解鎖位置(P1)中時,鎖定元件(132)允許操作器具(102)相對於把手(104)軸向移動。當設置在鎖定位置(P2)中時,鎖定元件(132)的卡爪(152)朝向弧形邊緣(146)的尾端(150)偏壓操作器具(102),使得卡爪(152)與操作器具(102)的環形槽(106)鄰接,以限制操作器具(102)相對於把手(104)的軸向移動。100‧‧‧工具102‧‧‧操作器具104‧‧‧把手106‧‧‧環形槽108‧‧‧環形槽的第一端110‧‧‧環形槽的第二端112‧‧‧第一突起區域114‧‧‧第二突起區域116‧‧‧中空內部
