[0023] Embodiment 1:

[0024] In this embodiment, Figure 1 As shown, an extended nut disassembly and assembly tool comprises a main rod 1, a support rod 2, a rod sleeve 3 and a nut sleeve 4. The rod sleeve 3 is rotatably mounted on one end of the main rod 1, and the nut sleeve 4 is slidably mounted on the other end of the main rod 1. The nut sleeve 4 is fixed to the main rod 1 by a pin 5. The support rod 2 is symmetrically mounted on the main rod 1 and is located between the rod sleeve 3 and the nut sleeve 4.

[0025] Generally, nut sleeves 4 (commonly known as sleeves) are prepared in various calibers to meet the disassembly and assembly of nuts of various specifications. When working, first select a nut sleeve 4 of appropriate size according to the caliber of the nut to be disassembled, and then use the pin 5 to fix the nut sleeve 4 on the far end of the main rod 1. Then the staff holds the handle at the near end of the main rod 1 with one hand ( Figure 1Use one hand to hold the top position in the figure (not marked in the figure), and use the other hand to drag the main rod 1 and push it toward the nut until the nut sleeve 4 and the nut cooperate with each other. Finally, grab the two support rods 2 with both hands and turn the tool to complete the disassembly.

[0026] When the screw rod is long, resulting in a long disassembly and assembly stroke of the nut, the worker holds the rod sleeve 3 with one hand and moves the support rod 2 with the other hand to rotate it quickly, thereby quickly disassembling and assembling the nut, which greatly saves time.

[0027] Preferably, anti-slip protrusions 6 are provided at both ends of the support rod 2 .

[0028] The anti-skid protrusion 6 can prevent the hand from slipping when the staff holds the support rod 2.

[0029] Preferably, a stiffening rod 7 is provided between the main rod 1 and the supporting rod 2 .

[0030] The main rod 1 is half as long as the other, and the stiffening rod 7 can stabilize the main rod 1 and reduce its shaking or deformation.

[0031] Embodiment 2:

[0032] Based on the above embodiments, this embodiment Figure 2 and Figure 3 As shown, a length adjustment assembly is provided between the main rod 1 and the nut sleeve 4. The length adjustment assembly comprises an inner rod 8, a threaded rod 9 and a hand wheel 10. The inner rod 8 is slidably mounted in the main rod 1, the nut sleeve 4 is slidably mounted on the outer end of the inner rod 8, and the nut sleeve 4 is fixed on the outer end of the inner rod 8 through a latch 5. The threaded rod 9 is rotatably mounted in the main rod 1, and the threaded rod 9 is threadedly connected to the inner rod 8, and the hand wheel 10 is mounted on the outer end of the threaded rod 9.

[0033] When the tool is too long or too short, the threaded rod 9 can be rotated by the hand wheel 10 to make the inner rod 8 rotate inside the main rod 1, thereby controlling the length of the inner rod 8 extending outside the main rod 1 and thus controlling the length of the tool.

[0034] Preferably, at least one slide bar 11 is provided on the outer periphery of the inner rod 8 along its axial direction, and a slide groove 12 slidably matched with the slide bar 11 is provided in the main rod 1 .

[0035] The cooperation between the slide bar 11 and the slide groove 12 can prevent the inner rod 8 from rotating and at the same time enhance its stability.

[0036] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
