DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will further describe the present application in detail Figures 1 - 3 with reference to the accompanying drawings.

[0020] The embodiment of the present application discloses a magnetic suction sleeve. Refer to Figure 1 、 Figure 2 、 Figure 3The present invention relates to a magnetic suction sleeve, comprising a columnar wrench 1, so that when using the device, after the sleeve 4 is placed outside the nut, the sleeve 4 is driven to rotate by rotating the wrench 1, so as to tighten the nut, and a connecting block 2 is fixedly connected to the lower surface of the wrench 1, and a groove-shaped mounting groove 3 is opened on the lower surface of the connecting block 2, and a sleeve 4 is clamped and connected to the inner wall of the mounting groove 3, so that the sleeve 4 can be quickly disassembled and installed, so as to facilitate rapid replacement with other types of sleeves 4, so as to be suitable for tightening nuts of different types, greatly improving work efficiency and work quality, and two clamping plates 5 are slidably connected to the inner top surface of the sleeve 4, and the sleeve 4 is connected with a block-shaped magnetic block 6 through the two clamping plates 5, and the magnetic block 6 is placed on the inner walls of the two clamping plates 5, so that when the magnetism is weakened, the magnetic block 6 can be quickly replaced, thereby effectively adsorbing the nut to prevent it from falling, and reducing maintenance costs.

[0021] Reference Figure 2 Two square groove-shaped guide grooves 7 are provided on the inner top surface of the installation groove 3, and two rectangular parallelepiped guide blocks 8 are fixedly connected to the upper surface of the sleeve 4, and the guide blocks 8 slide relatively with the inner wall of the guide groove 7, and an arc-shaped groove-shaped clamping groove 9 is provided on the outer surface of the sleeve 4, and an arc-shaped strip-shaped clamping ring 10 is fixedly connected to the inner side wall of the installation groove 3, and the clamping ring 10 can be clamped on the inner wall of the clamping groove 9, and two arc-shaped grooves 11 are provided on the outer surface of the sleeve 4 below the clamping groove 9, and two groove-shaped limiting grooves 12 are provided on the inner side wall of the installation groove 3 at the lower surface of the clamping ring 10, and the inner wall of the limiting groove 12 is elastically slidably connected with a block-shaped limiting block 13 through a spring, and the limiting block 13 can be clamped on the inner wall of the groove 11, so that when it is necessary to replace the sleeve 4 with a different model, the limiting block 13 can be pressed to keep it away from the groove. The inner wall of 11, then the sleeve 4 is slid downward and pulled out, so that the locking ring 10 is separated from the inner wall of the slot 9, thereby completing the quick disassembly of the sleeve 4, and then the limit block 13 is pressed to shrink it to the inner wall of the limit groove 12. At this time, the spring is in a compressed state, and then the sleeve 4 that can be suitable for other types of nuts is slid downward along the installation groove 3, and at the same time, the guide block 8 is slid upward along the inner wall of the guide groove 7, so that the installation is guided and positioned by the guide block 8, and then the locking ring 10 is engaged with the inner wall of the slot 9, thereby performing a preliminary engagement of the sleeve 4, and then under the resetting action of the spring, the limit block 13 rebounds and engages with the inner wall of the groove 11, thereby stably fixing the sleeve 4 to the inner wall of the installation groove 3, thereby completing the quick installation of the sleeve 4, thereby completing the quick replacement of the sleeve 4, so that it can be suitable for nuts of different types.

[0022] Reference Figure 3, a groove-shaped sliding groove 14 is formed on the inner top surface of the sleeve 4, and a double-headed lead screw 15 is rotatably connected to the inner side wall of the sliding groove 14. The outer surface of the double-headed lead screw 15 is relatively screwed with both clamping plates 5, so that by rotating the double-headed lead screw 15, the two clamping plates 5 slide away from each other, so that the magnet 6 can be quickly removed. Then, the replaced magnet 6 is placed between the two clamping plates 5. Subsequently, by rotating the double-headed lead screw 15 in the reverse direction, the two clamping plates 5 slide towards each other, thereby stably fixing the magnet 6, thus ensuring the magnetism of the device and ensuring that the nut can be stably adsorbed during work to prevent it from falling.

[0023] The implementation principle of a magnetic adsorption sleeve in an embodiment of the present application is as follows: Select a magnet 6 with an appropriate magnetic force according to the model size of the nut or screw to be tightened. Place the magnet 6 between the two clamping plates 5. Subsequently, by rotating the double-headed lead screw 15, the two clamping plates 5 slide towards each other, thereby stably fixing the magnet 6, so as to ensure that the nut can be stably adsorbed during work to prevent it from falling. Then, by pressing the limit block 13, it contracts into the inner wall of the limit groove 12. At this time, the spring is in a compressed state. Subsequently, the sleeve 4 applicable to other model nuts is slid downward along the installation groove 3, and at the same time, the guide block 8 slides upward along the inner wall of the guide groove 7, so as to guide and position the installation through the guide block 8. Then, the snap ring 10 is snapped into the inner wall of the card slot 9, thereby initially snapping the sleeve 4. Subsequently, under the reset action of the spring, the limit block 13 rebounds and is snapped into the inner wall of the groove 11, thereby stably fixing the sleeve 4 on the inner wall of the installation groove 3, thus completing the rapid installation of the corresponding model sleeve 4. When in use, after placing the sleeve 4 outside the nut, rotate the wrench 1 to drive the sleeve 4 to rotate, thereby tightening the nut.
