[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-3The slotted locking nut disassembler shown comprises an outer sleeve 1, the top of the outer sleeve 1 is connected with an inner sleeve 2, the bottom of the outer sleeve 1 is provided with a rotating part, the rotating part comprises a hexagonal column 8, and the hexagonal column 8 is provided at the bottom end of the outer sleeve 1;

[0026] It should be noted that the outer sleeve 1 and the inner sleeve 2 are both made of chrome vanadium steel, which has excellent wear resistance and high strength and is suitable for use under high loads. The hexagonal column 8 is fixed to the bottom of the outer sleeve 1 by welding, and the user is connected to the pneumatic wrench to realize the rotation of the outer sleeve 1. The top of the top of the outer sleeve 1 has a separate design. When the inner sleeve 2 is inserted into the inner cavity of the outer sleeve 1, the separation is bonded with a fixed adhesive to prevent the inner sleeve 2 and the outer sleeve 1 from being separated from each other;

[0027] A fixing member for fixing the slotted locking nut is symmetrically arranged on the outer top of the inner sleeve 2;

[0028] Specifically, the fixing member includes a screw rod 4, one end of which is threadedly inserted into the side of the inner sleeve 2, a tightening nut 5 is sleeved on the outer side of the screw rod 4 and located outside the inner sleeve 2, and a top screw 6 is threadedly inserted into the inner cavity of the inner sleeve 2 at one end of the screw rod 4;

[0029] It should be noted that a threaded hole for inserting the screw 4 is provided at the top of the side of the inner sleeve 2, and a rotating transverse groove 401 is provided at the other end of the screw 4, so that the user can use a flat-nosed screwdriver to rotate the screw 4, and the sleeve of the tightening nut 5 is used to fix the position of the screw 4 to prevent the position of the screw 4 from loosening. A cylindrical threaded hole for inserting a top screw 6 is provided at one end of the screw 4. The top screw 6 adopts a round-headed cylindrical shape and can be rotated in the cylindrical threaded hole. According to the different specifications of the slotted locking nut, the insertion depth of the top screw 6 and the cylindrical threaded hole is adjusted, so that the slotted locking nut cannot rotate in the inner cavity of the inner sleeve 2;

[0030] An adjustment member is provided at the interlacing point between the outer sleeve 1 and the inner sleeve 2;

[0031] Specifically, the adjustment member includes a limit bolt 3, one end of which is threadedly inserted and connected to the outside of the outer sleeve 1, one end of the limit bolt 3 is provided with a friction block 301 located inside the outer sleeve 1, and the other end of the limit bolt 3 is fixedly connected to a torsion rod 302;

[0032] It should be noted that the outer side of the outer sleeve 1 is provided with a plurality of fixing holes 102 for inserting the limit bolts 3, and the inner wall of the fixing hole 102 is provided with a thread for rotating the limit bolts 3. The friction block 301 is made of rubber mixed with nylon thread, and is connected with the limit bolts 3 by glue. The user rotates the torsion bar 302 so that the friction block 301 tightly squeezes the outer side of the inner sleeve 2. When the slotted locking nut is difficult to rotate, the number of the limit bolts 3 can be increased, so that the inner sleeve 2 cannot rotate in the inner cavity of the outer sleeve 1.

[0033] Specifically, a support ring 9 is provided on the outer side of the inner sleeve 2 and located in the inner cavity of the outer sleeve 1, and a limiting ring column 7 is fixedly connected to the bottom end of the inner sleeve 2 and located in the inner cavity of the outer sleeve 1;

[0034] It should be noted that the inner wall of the outer sleeve 1 is provided with a limiting ring groove 101 for the movement of the limiting ring column 7 and the support ring 9, the inner side of the support ring 9 is welded and fixed to the outer side of the inner sleeve 2, the limiting ring column 7 and the inner sleeve 2 are fixed by welding, and the limiting ring column 7 and the support ring 9 jointly support the inner sleeve 2, so that the inner sleeve 2 does not tilt in the inner cavity of the outer sleeve 1, and the outer sleeve 1 is limited from being separated from the inner sleeve 2;

[0035] During actual use, the user inserts the screw 4 through the symmetrical thread on the top of the inner sleeve 2, locks the position of the screw 4 with the tightening nut 5, and inserts the top screw 6 of the screw 4 located in the cavity of the inner sleeve 2 into the slot of the slotted locking nut to fix the position of the inner sleeve 2 and the slotted locking nut. Compared with using a crescent wrench to rotate the slotted locking nut, this design can fix the position of the inner sleeve 2 and the slotted locking nut, making it convenient for the user to quickly rotate the hexagonal column 8 with a pneumatic wrench, thereby rotating the sleeve 1, and the limit bolt 3 fixes the inner sleeve 2 so that it cannot rotate in the inner cavity of the outer sleeve 1, thereby driving the rotation of the slotted locking nut. At the same time, the telescopic adjustment of the inner and outer sleeves facilitates the disassembly and installation of the slotted locking nut on the long screw.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
