The invention discloses a clamp spreader facilitating removal of clamping feet, and belongs to the technical field of clamp spreaders. The clamp spreader facilitating removal of the clamping feet comprises spreader rods, wherein a movable groove is formed in the outer surface of each spreader rod; an inserting rod is inserted into the movable grooves; a stop block is fixedly connected to one end of the inserting rod; and a thread is arranged at the other end of the inserting rod. According to the clamp spreader,the movable grooves are formed in the outer surfaces of the spreader rods separately, the inserting rod is inserted into the movable grooves, the other end of the inserting rod is in threaded connection with a nut, and the movable grooves, the inserting rod and the nut are arranged in a matched manner, so that the inserting rod has a certain limiting effect on the spreader rod in the movable grooves, and a clamp can normally clamp steel materials; and a spring is arranged at the bottom end of the inserting rod, and fixing blocks are fixedly connected to two ends of the spring, so that the spreader rod has certain rebound force after clamping the steel materials by means of the operation that the spreader rods compress the spring.

    本发明公开了一种便于拆卸夹脚的夹钳吊具,属于夹钳吊具技术领域。一种便于拆卸夹脚的夹钳吊具,包括吊具杆,所述吊具杆的外表面开设有活动槽,所述活动槽的内部插接有插接杆,所述插接杆的一端固定连接有阻挡块,所述插接杆的另一端设置有螺纹;本发明通过吊具杆的外表面开设有活动槽,活动槽的内部插接有插接杆,插接杆的另一端螺纹连接有螺帽,利用活动槽、插接杆和螺帽的相互配合设置,能够使插接杆在活动槽内部对吊具杆起到一定限位的作用,确保夹具可以正常的夹取钢材物料,插接杆的底端设置有弹簧,弹簧的两端均固定连接有固定块,利用吊具杆压缩弹簧的操作,能够使吊具杆在夹取钢材物料后有一定的反弹力。
