摘要： The invention provides a quick blade attachment structure For quickly but securely attaching and detaching one or a plurality of blades to and from a mower. A rotary member (3) of a mower (1) includes a blade holder (4) and a support member (5) coaxially attached to the blade holder (4) to allow pivotal movement of the support member (5). A pair of blades (23,23) are supported by ends (9a, 9a) of rimmed pins (9,9) projected from a lower surface (4a) of the blade holder (4). A wave washer (16) is interposed between the support member (5) and a cap (17). When the rotary member (3) is assembled by a clamp screw (18), pressing force of the wave washer (16) allows the support member (5) to be rotated integrally with the blade holder (4). The support member (5) further has a pair of grooves (12). Each groove (12) includes a deeper portion (13) which receives the end (9a) of the rimmed pin (9) through relative rotation of either the blade holder (4) or the support member (5) against the pressing force of the wave washer (16), and a guide element (14) which the end (9a) of the rimmed pin (9) moves along to be eventually released from the support member 5. The structure of the invention allows the pair of blades (23,23) to be quickly and easily attached to and detached from the mower (1) by simple rotation of either the blade holder (4) or the support member (5). The structure of the invention also ensures secure attachment of the blades (23,23) to the mower (1). The grooves (12,12) allow the rimmed pins (9,9) to be smoothly moved along the guide elements (14,14) and securely received by the deeper portions (13,13).
摘要翻译：本发明提供了一种快速的叶片附接结构，用于快速但牢固地将一个或多个叶片与割草机连接和分离。割草机（1）的旋转构件（3）包括刀片保持器（4）和同轴地附接到刀片保持器（4）的支撑构件（5），以允许支撑构件（5）的枢转运动。一对刀片（23,23）由从刀片保持器（4）的下表面（4a）突出的边缘销（9,9）的端部（9a，9a）支撑。波形垫圈（16）插入在支撑构件（5）和盖（17）之间。当通过夹紧螺钉（18）组装旋转构件（3）时，波形垫圈（16）的按压力允许支撑构件（5）与刀架（4）一体旋转。支撑构件（5）还具有一对凹槽（12）。每个凹槽（12）包括较深部分（13），其通过刀片保持器（4）或支撑构件（5）的相对旋转抵抗所述边缘销（9）的压紧力来容纳所述边缘销（9）的端部（9a）波浪垫圈（16）和引导元件（14），其中边缘销（9）的端部（9a）沿着移动以最终从支撑构件5释放。本发明的结构允许一对叶片（23 ，23）通过刀片保持器（4）或支撑构件（5）的简单旋转而快速且容易地附接到割草机（1）和从割草机（1）分离。本发明的结构还确保了叶片（23,23）与割草机（1）的牢固连接。凹槽（12,12）允许边缘销（9,9）沿着导向元件（14,14）平滑地移动并被较深部分（13,13）牢固地接收。
