[0024] A threaded sleeve 14 is rotatably connected to the shell body 1, one end of the threaded sleeve 14 is fixedly connected to a handle 15, a threaded screw rod 16 is threadedly connected to the threaded screw rod 16, a slide rod 17 is fixedly connected to the shell body 1, and a pad 18 is fixedly connected to one end of the slide rod 17. A handle 19 is fixedly connected to the bottom of the shell body 1, and a handle 20 is fixedly connected to the bottom of the shell body 1. A hole 21 is provided on the shell body 1, and a hole 3 22 is provided on the shell body 1. A bolt 14 passes through the rotating shaft 3, the bolt 14 passes through the sleeve 15, the hole 21 passes through the shell body 1, and the hole 3 22 passes through the shell body 1. Several groups of holes 12 are provided, and a spring 2 13 is provided in the sleeve 15. When using the new detachable double-bolt device, the staff disassembles and replaces the sleeve 15 according to the caliber of the tightened double bolts, so that the device can easily adapt to double bolts of different calibers, further improving the adaptability and work efficiency of the device.

[0025] Working principle: When using the new detachable double-bolt device, the staff first twists the handle 15, the handle 15 drives the threaded sleeve 14 to rotate on the housing 1, the threaded sleeve 14 drives the threaded screw 16 to move forward through the threaded connection, the threaded screw 16 drives the slide bar 17 to slide forward on the housing 1, and the slide bar 17 drives the pad 18 to slide forward. When it is adjusted to the required position, it is used to ensure that the exposed length of the double bolts is consistent when tightening the double bolts, so that each group of double bolts can be uniformly stressed during subsequent fixing, thereby improving the fastening quality of the object, and then the staff can adjust the double bolts according to the requirements. The thread length of the double bolts pulls the pressure plate 10, and the pressure plate 10 drives the connecting rod 9 to move by rotating on the bracket 7, and compresses the spring 11 at the same time, and then the connecting rod 9 drives the clamping column 8 to slide on the bracket 7, so that one end of the clamping column 8 leaves the hole 12 on the sleeve 5, and then the bracket 7 is pulled by the length of the double bolt threads, and the bracket 7 drives the baffle 6 to slide in the sleeve 5 by compressing the spring 2 13 or the rebound of the spring 2 13. After sliding to a certain position, the pressure plate 10 is released, and the spring 11 rebounds on the pressure plate 10, so that the pressure plate 10 passes The connecting rod 9 drives the clamping column 8 to slide on the bracket 7, so that the clamping column 8 is clamped into the corresponding hole 12 to complete the fixation of the baffle 6, which is used to adjust the internal thread length of the sleeve 5 according to the thread length of the double bolts, so that it is suitable for fastening the double bolts with different thread lengths into the objects to be fixed. Then the staff aligns the sleeve 5 with the double bolts to be fastened by holding the handle 19 and the handle 20, and then turns on the motor 2. The motor 2 drives the shaft 3 to rotate on the housing 1, and the shaft 3 drives the sleeve 5 to rotate through the meshing connection. When the sleeve 5 rotates, the double thread When the bolt is fitted on the baffle 6 through the thread in the sleeve 5, the baffle 6 prevents the double bolts from entering the sleeve 5, so that the sleeve 5 drives the double bolts to be tightened into the object. When it is necessary to replace the sleeve 5 of different diameters, the staff unscrews the bolt 4, then pulls out the sleeve 5, and then replaces the sleeve 5 of the required caliber, so that one end of the sleeve 5 is engaged with the rotating shaft 3, and then the bolt 4 is turned to reset. It is used to disassemble and replace the sleeve 5 according to the caliber of the tightened double bolts, so as to facilitate the subsequent application of the staff and improve work efficiency.
