Zusammenfassung: | The utility model discloses a releasing type inner slip overshot which comprises a pressurizing separation mechanism and a slip clamping mechanism which are connected up and down. The slip clamping mechanism comprises an elastic component (13), a rail cylinder (12) and an outer sleeve (10) which are sequentially arranged in a sleeving mode from inside to outside. The rail cylinder (12) is in a vertical state; the utility model relates to a high-efficiency energy-saving lamp. The diameter of the inner surface of the rail cylinder (12) is gradually reduced; a plurality of slips (14) are connected in the rail cylinder (12); the slips (14) are arranged at intervals in the circumferential direction of the rail cylinder (12), a slip guide rail (20) is arranged on the inner surface of the rail cylinder (12), the slips (14) can move along the slip guide rail (20) and enable the clamping radius of the slips (14) to be increased or decreased, and the elastic component (13) can provide restoringforce for the slips (14). |
