The invention relates to a quick change device of an excavator. Comprising a connecting frame body, and a connecting position used for being connected with an excavator is arranged on the upper portion of the connecting frame body; the lock hook mechanism is arranged on the lower portion of the connecting frame body, the lock hook mechanism comprises a front lock hook and a rear lock hook which are connected to the connecting frame body, an opening of the front lock hook and an opening of the rear lock hook are oppositely arranged, and the front lock hook and the rear lock hook are connected with a front pin shaft and a rear pin shaft of the accessory respectively; a sliding block connected with the connecting frame body in a sliding mode is connected to the rear locking hook, an elastic driving mechanism is arranged in the connecting frame body, the sliding block is connected to the elastic driving mechanism, and the elastic driving mechanism pushes the rear locking hook to move back to the front locking hook. The movable lock hook adopts a mechanical translation type structure, most load of an excavator accessory directly acts on a mechanical body, namely the connecting frame body instead of acting on the hydraulic cylinder, the hydraulic cylinder is protected, and the service life of the hydraulic cylinder is prolonged.
本发明涉及一种挖掘机快换装置；包括：连接架本体，连接架本体上部布置有用于与挖机连接的连接位；锁钩机构，锁钩机构布置于连接架本体下部，锁钩机构包括连接于连接架本体的前部锁钩和后部锁钩，前部锁钩和后部锁扣的开口互相背向设置，前部锁钩和后部锁钩分别连接属具的前部销轴和后部销轴；后部锁钩上连接有与连接架本体滑动连接的滑动块，在连接架本体内布置有弹性驱动机构，滑动块连接于弹性驱动机构上，弹性驱动机构推动后部锁钩背向前部锁钩移动；本产品的活动锁钩采用机械平动式结构，将挖机属具的大部分载荷直接作用在机械本体也就是连接架本体上，而不是作用在液压缸上，保护了液压缸增加了使用寿命。
