The technical scheme that solves the problems of the technologies described above is:
A kind of instrument that picks and places radioactive source, it is made up of lower clamping bar, collet head, spring, connecting rod, handle, the lower end of connecting rod is vertically welded in the central authorities of lower clamping bar, the diameter of lower clamping bar picks and places the width in hole less than radioactive source, and the length that the length of lower clamping bar and radioactive source pick and place the hole is complementary, and collet head is enclosed within on the connecting rod, spring housing is on the connecting rod above the collet head, there is pad at the two ends of spring, and handle is T-shaped, and the montant lower end of small end and handle is for removably connecting.
The above-mentioned instrument that picks and places radioactive source, described small end has screw thread, and the lower end of handle montant is welded with nut, and the screw thread of small end and handle montant lower end nut are complementary.
The above-mentioned instrument that picks and places radioactive source, described small end has horizontal pin-and-hole, and there is sleeve the lower end of handle montant, and horizontal pin-and-hole is arranged on the sleeve, and the trepanning of sleeve and small end diameter are complementary, and connecting rod pin-and-hole and sleeve pin-and-hole are complementary.
The beneficial effects of the utility model are:
Lower clamping bar of the present utility model stretches into radioactive source and picks and places in the hole back rotation, and lower clamping bar and collet head are clamped radioactive source, and spring can make its clamping, can take out radioactive source fast steadily, prevents from that radioactive source from dropping human body is damaged, and guarantees to keep the safety in production.The utility model is simple in structure, safe and reliable, respond well.
Description of drawings
Fig. 1 is structural representation of the present utility model;
