The invention discloses a labor-saving chain block convenient to use, and relates to the technical field of chain blocks, the labor-saving chain block convenient to use comprises a deck and a folding mechanism, the folding mechanism comprises a lifting block, a first supporting plate, a second supporting plate and a connecting frame, and the lifting block movably sleeves a supporting column; the ends, close to the supporting column, of the two first supporting plates are movably installed in the middle of the top end of the side wall of the supporting frame through rotating shafts, the two second supporting plates are located between the two first supporting plates, and the ends, close to the supporting frame, of the second supporting plates are movably installed on the side wall of the lifting block through rotating shafts. When the first supporting plate and the second supporting plate drive the connecting frame to move to the maximum distance from the deck and the maximum distance from the supporting frame, the connecting frame drives the hoisting mechanism to stretch out of the deck to conduct hoisting work, the situation that a worker stands beside the deck to pull a zipper and is prone to falling down is avoided, and potential safety hazards are reduced; and the marine space is saved through folding placement, and the practicability of the device is improved.

    本发明公开了一种方便使用的省力型手拉葫芦,涉及手拉葫芦技术领域,包括甲板,折叠机构,所述折叠机构包括升降块、第一支撑板、第二支撑板和连接架,所述升降块活动套接在支撑柱外,所述第一支撑板共有两根且靠近支撑柱的一端分别通过转轴活动安装在支撑架的侧壁顶端中间,所述第二支撑板共有两根且位于两根第一支撑板之间,且靠近支撑架的一端通过转轴活动安装在升降块的侧壁。本发明通过第一支撑板和第二支撑板带动连接架移动到与甲板间距最大且与支撑架间距最大时,此时连接架带动起重机构伸出甲板进行起重工作,避免工作人员站在甲板边拉动拉链容易摔倒,减小了安全隐患,并且通过折叠放置节省了船用空间,提高了装置的实用性。
