Stud sleeve

The invention discloses a double-end stud sleeve which comprises an ejector rod, a connecting rod, a fixing sleeve and a threaded plate, the ejector rod is connected with the connecting rod, the connecting rod is fixedly sleeved with the fixing sleeve, and the threaded plate is connected to the end, away from the ejector rod, of the fixing sleeve; the threaded plate is provided with a first threaded hole used for being connected with a double-end stud. A first limiting hole is formed in the end, close to the connecting rod, of the threaded plate, a clamping structure is slidably connected into the first limiting hole, and the first limiting hole communicates with the first threaded hole. And the connecting rod is connected with the ejector rod through an unfreezing mechanism. According to the double-end stud sleeve, it is guaranteed that the connecting torque of a double-end stud reaches the standard, the reworking rate of tightening of the double-end stud is greatly reduced, and the assembling efficiency of
