The invention relates to bell-shaped tongs. The bell-shaped tongs comprise a cylinder body; guide rods are horizontally arranged on the upper surface of the cylinder body at intervals; guide column check blocks are arranged on the side faces, facing a central shaft of the cylinder body, of the guide rods; the guide column check blocks are located on the same horizontal plane; a cross beam is arranged between the cylinder body and the guide column check blocks; the horizontally-arranged cross beam is movably inserted into the guide rods in a penetrating mode; a clamping and loosening control mechanism is arranged on the upper surface of the cross beam; clamping parts are hinged to the two ends of the cross beam located outside the cylinder body; open grooves are formed in the positions, corresponding to the clamping parts, of the cylinder body; hook-shaped rods of the clamping parts are hinged into the open grooves; each hook-shaped rod comprises a vertical rod and a connecting rod; anincluded angle is formed between the downward inclined connecting rod located outside the cylinder body and the vertical rod; and the upper end of each connecting rod is hinged with the correspondingcross beam end through a pull rod. Due to the cooperative arrangement of the clamping and loosening control mechanism, the cross beam and the cylinder body, an external graphite electrode can be quickly clamped and transferred, and the bell-shaped tongs are suitable for industrial production and have very high practicability.
本发明涉及钟形钳。该装置包括有筒体,筒体上表面水平间隔设置有导向杆,朝向筒体中心轴的各导向杆侧面均设置有导柱挡块,各导柱挡块位于同一水平面上,位于筒体与导柱挡块之间设置有横梁,水平设置的横梁活动穿插在各导向杆上,横梁上表面上设置有夹松控制机构,位于筒体外的横梁两端均铰接有夹持部件,各夹持部件对应的筒体上开设有开口槽,各开口槽内铰接有夹持部件的钩型杆,钩型杆包括有竖杆以及连杆,位于筒体外的倾斜向下连杆与竖杆之间形成夹角,各连杆上端头与对应的横梁端头经拉杆铰接。由于夹松控制机构、横梁以及筒体之间的配合设置,能够快速地将外设石墨电极进行夹持转运,该装置适用于工业生产中,具有很强的实用性。
