The invention discloses an adjustable magnetic sling comprising an outer box, wherein a permanent magnet block is fixedly installed inside the outer box, a concave groove is provided on the top of thepermanent magnet block, the side wall of the permanent magnet block is fixedly installed with a magnetic switch, a lifting ring is fixedly connected inside the concave groove, the top of the permanent magnet block is fixedly installed with a connecting plate, the top of the connecting plate is movably installed with a rotating frame, and a limit hole is provided inside the rotating frame. By adopting neodymium iron boron permanent magnet material as the core of the product, the invention can be used without electricity when working, and is not easy to generate heat during the working. The optimized magnetic circuit design makes the residual magnetism almost zero. The neodymium iron boron material makes the product smaller, lifting force stronger, self weight lighter, probability of failure lower and service life longer. The design of a telescopic rod can make the sling absorb various irregular-shaped metal objects more stably. The design of a clamping block can increase the stabilityand safety of the permanent magnet block during adsorption.

    本发明公开了一种可调式磁力吊具,包括外箱,所述外箱的内部固定安装有永磁块,所述永磁块的顶部开设有凹型槽,所述永磁块的侧壁固定安装有磁力开关,所述凹型槽的内部固定连接有吊环,所述永磁块的顶部固定安装有连接板,所述连接板的顶部活动安装有旋转架,所述旋转架的内部设有限位孔。本发明采用钕铁硼永磁材料为产品内核,工作时不用通电即可使用,且工作时不易发热,优化的磁路设计使剩磁几乎为零,钕铁硼材料使产品体积更小、吊装力更强、自身重量更轻、产生故障的几率更低且使用寿命更长,伸缩杆设计可以使吊具可以更稳固的吸附各种不规则形状的金属物体,夹块设计可以增加永磁块吸附时的稳定性和安全性。
