[0002] Sockets are key components in the power tool industry, primarily used to transmit the rotational torque of electric screwdrivers to fasteners such as screws and nuts, and to accommodate different sizes of bits or workpieces. With the increasing demands for automated assembly and precision manufacturing, sockets need to maintain stable connection performance under high-speed, high-torque conditions, while also meeting requirements for quick changeover, anti-slip properties, and durability.

[0003] Among them, announcement number CN210757403U discloses a magnetic sleeve that is easy to assemble and disassemble, including a nut positioning sleeve, a rotating sleeve connected to the nut positioning sleeve, and an annular magnet disposed between the nut positioning sleeve and the rotating sleeve; the lower end of the nut positioning sleeve has a nut receiving cavity, the middle part has an annular magnet placement ring, the upper end is connected to the rotating sleeve, the annular magnet has an opening in the middle, and the middle part of the rotating sleeve has a cavity to accommodate the passage of the screw. This utility model can prevent bolts and nuts from slipping off, ensure personal safety and equipment safety, reduce safety hazards during the process of picking up fallen objects, improve work efficiency, shorten working time, improve power supply reliability, facilitate efficient live-line work, and continuously ensure a stable power supply for residents.

[0004] However, in actual use, since the nut positioning sleeve and the rotating sleeve are fixed by plugging, they can be disassembled and reassembled at will. But under high-speed rotation, the connection stability is low and they are prone to falling off, which may cause safety hazards.

[0005] Therefore, it is necessary to invent a highly stable strong magnetic sleeve to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a highly stable strong magnetic sleeve to solve the problem that the connection between the nut positioning sleeve and the rotating sleeve is unstable under high-speed rotation, making it easy to fall off and causing safety hazards.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a highly stable strong magnetic sleeve, comprising a fixed sleeve, a nut sleeve fixedly connected to the lower end of the fixed sleeve, a nut groove formed on the lower surface of the nut sleeve, a rotating sleeve inserted inside the fixed sleeve, a strong magnetic block disposed inside the fixed sleeve, and a fixing assembly disposed between the fixed sleeve and the rotating sleeve, the fixing assembly comprising a limiting groove, a limiting ball, a first support ring, a support spring, a positioning sleeve, an abutment ring, a second support ring, a positioning ring, and a positioning groove.

[0008] By adopting the above technical solution, the lower end of the rotating sleeve is inserted into the inside of the fixed sleeve. At this time, the positioning sleeve is pushed upward, and the abutment ring pushes multiple sets of limiting balls inward, locking them into the inside of the positioning groove, thereby effectively improving the stability of the connection between the fixed sleeve and the rotating sleeve. At the same time, the positioning sleeve is slid downward, so that the abutment ring disengages from the side of the limiting balls. At this time, the positioning sleeve can be pulled out, which is convenient for disassembling the positioning sleeve.

[0009] Optionally, multiple sets of limiting grooves are provided on the side wall of the fixed sleeve near the upper end, and limiting balls are engaged inside the limiting grooves.

[0010] By adopting the above technical solution, the limiting ball can slide inward and outward inside the limiting groove.

[0011] Optionally, the first support ring is fixedly connected to the side wall of the fixed sleeve near the lower end, the support spring is sleeved on the surface of the fixed sleeve, and the lower end of the support spring abuts against the upper surface of the first support ring.

[0012] By adopting the above technical solution, the first support ring supports the lower end of the support spring.

[0013] Optionally, the positioning sleeve is fitted onto the surface of the fixed sleeve, the second support ring is fixedly connected to the middle of the positioning sleeve, and the upper end of the support spring abuts against the lower surface of the second support ring.

[0014] By adopting the above technical solution, the second support ring supports the upper end of the support spring.

[0015] Optionally, the abutment ring is fixedly connected to the upper part of the inner wall of the positioning sleeve, the positioning ring is fixedly connected to the lower end of the positioning sleeve, and the abutment ring, the second support ring, and the positioning ring are all slidably connected to the fixed sleeve.

[0016] By adopting the above technical solution, the support spring pushes the positioning sleeve upward through the second support ring, so that the abutment ring is located on the side of the limiting ball, and at the same time the positioning ring abuts against the lower surface of the first support plate.

[0017] Optionally, the lower end of the fixing sleeve is provided with a slot, and the strong magnetic block is engaged inside the slot.

[0018] By adopting the above technical solution, both the card slot and the strong magnetic block are hexagonal, which improves the stability of the strong magnetic block inside the card slot.

[0019] Optionally, a locking block is fixedly connected to the lower end of the rotating sleeve, and the locking block is locked inside the slot.

[0020] By adopting the above technical solution, the locking block is hexagonal, and the rotating sleeve drives the fixed sleeve and nut sleeve to rotate through the cooperation of the locking block and the locking groove.

[0021] Optionally, the nut sleeve and the strong magnetic block are both provided with a first connecting hole, and the rotating sleeve and the locking block are both provided with a second connecting hole.

[0022] By adopting the above technical solution, when the nut and the lead screw are connected, as the nut is pushed downwards, the lead screw will be inserted into the interior of the first connecting hole and the second connecting hole.

[0023] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0024] This invention involves inserting the lower end of the rotating sleeve into the interior of the fixed sleeve. When the positioning sleeve is pushed upward, the abutment ring pushes multiple sets of limiting balls inward, locking them into the positioning groove and securing the rotating sleeve. Simultaneously, the positioning sleeve is slid downward, causing the abutment ring to disengage from the side of the limiting balls, allowing the rotating sleeve to be pulled out. This facilitates the assembly and disassembly of the fixed sleeve and the rotating sleeve while effectively improving the stability of the connection between them. Attached Figure Description

Detailed Implementation

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1 to 4The illustrated high-stability magnetic sleeve includes a fixed sleeve 1, a nut sleeve 11 fixedly connected to the lower end of the fixed sleeve 1, a nut groove 12 formed on the lower surface of the nut sleeve 11, a rotating sleeve 3 inserted inside the fixed sleeve 1, a strong magnetic block 13 disposed inside the fixed sleeve 1, a slot 19 formed at the lower end of the fixed sleeve 1, the strong magnetic block 13 being engaged inside the slot 19, a locking block 31 fixedly connected to the lower end of the rotating sleeve 3, the locking block 31 being engaged inside the slot 19, a first connecting hole 18 formed inside the nut sleeve 11 and the strong magnetic block 13, and a second connecting hole 33 formed inside the rotating sleeve 3 and the locking block 31, and a fixing assembly provided between the fixed sleeve 1 and the rotating sleeve 3, the fixing assembly including a limiting groove 14, a limiting ball 15, a first support ring 16, a support spring 17, a positioning sleeve 2, an abutment ring 21, a second support ring 22, a positioning ring 23 and a positioning groove 32.

[0034] During the assembly of the fixed sleeve 1 and the rotating sleeve 3, the strong magnetic block 13 is first placed inside the slot 19. Then, the lower end of the rotating sleeve 3 is inserted into the fixed sleeve 1. At this time, the locking block 31 will be inserted into the slot 19 and push the strong magnetic block 13 to the bottom. Then, the positioning sleeve 2 and the abutment ring 21 are used to push the limiting ball 15 inward and lock the limiting ball 15 inside the positioning groove 32. This locks and fixes the rotating sleeve 3, making it easier to assemble and disassemble the fixed sleeve 1 and the rotating sleeve 3, while improving the stability of the connection between the fixed sleeve 1 and the rotating sleeve 3, thereby effectively improving the safety of use.

[0035] In addition, the driving component in this embodiment is a motor shaft or a handle. During use, the upper end of the rotating sleeve 3 is connected to the motor shaft or handle, and the hexagonal nut or hexagonal screw is locked inside the nut groove 12. The strong magnetic block 13 magnetically attracts and fixes the hexagonal nut or hexagonal screw. At this time, the motor shaft or handle drives the rotating sleeve 3 to rotate, the rotating sleeve 3 drives the fixed sleeve 1 to rotate, the fixed sleeve 1 drives the nut sleeve 11 to rotate, and the nut sleeve 11 drives the hexagonal nut or hexagonal screw to rotate.

[0036] See Figures 2 to 5 The fixed sleeve 1 has multiple sets of limiting grooves 14 near the upper end of its side wall. Limiting balls 15 are engaged inside the limiting grooves 14. The first support ring 16 is fixedly connected to the side wall of the fixed sleeve 1 near the lower end. The support spring 17 is sleeved on the surface of the fixed sleeve 1, and the lower end of the support spring 17 abuts against the upper surface of the first support ring 16. The positioning sleeve 2 is sleeved on the surface of the fixed sleeve 1. The second support ring 22 is fixedly connected to the middle of the positioning sleeve 2, and the upper end of the support spring 17 abuts against the lower surface of the second support ring 22. The abutting ring 21 is fixedly connected to the inner wall of the positioning sleeve 2 near the upper end. The positioning ring 23 is fixedly connected to the lower end of the positioning sleeve 2. The abutting ring 21, the second support ring 22, and the positioning ring 23 are all slidably connected to the fixed sleeve 1.

[0037] Specifically, during the splicing process of the fixed sleeve 1 and the rotating sleeve 3, the positioning sleeve 2 is first slid downwards. At this time, the outer side of the limiting ball 15 lacks a limit. Then, the lower end of the rotating sleeve 3 is inserted into the interior of the fixed sleeve 1. When the rotating sleeve 3 is inserted to the bottom, the positioning groove 32 is just inside the limiting ball 15. Then, the positioning sleeve 2 is slid upwards. At this time, the abutment ring 21 will push multiple sets of limiting balls 15 inwards, locking the limiting balls 15 inside the positioning groove 32, thereby locking and fixing the fixed sleeve 1 and the rotating sleeve 3. Under the action of the support spring 17, without applying external force, the positioning sleeve 2 is effectively prevented from sliding downwards, and the position of the abutment ring 21 is prevented from shifting, thereby further improving the connection stability.

[0038] Meanwhile, when it is necessary to disassemble the fixed sleeve 1 and the rotating sleeve 3, simply apply external force to slide the positioning sleeve 2 downward, so that the abutment ring 21 moves to the lower side of the limiting ball 15. At this time, the rotating sleeve 3 can be pulled upward to detach the rotating sleeve 3 from the inside of the fixed sleeve 1.

[0039] The working principle of this utility model is as follows: By inserting the lower end of the rotating sleeve 3 into the inside of the fixed sleeve 1, the positioning sleeve 2 is pushed upward, and the abutment ring 21 pushes multiple sets of limiting balls 15 inward, locking them into the inside of the positioning groove 32, thus locking and fixing the rotating sleeve 3. At the same time, the positioning sleeve 2 is slid downward, so that the abutment ring 21 disengages from the side of the limiting balls 15, and the rotating sleeve 3 can be pulled out. This facilitates the disassembly and assembly of the fixed sleeve 1 and the rotating sleeve 3, while effectively improving the stability of the connection between the fixed sleeve 1 and the rotating sleeve 3.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
