[0021] like Figure 1 to Figure 2 As shown, in this embodiment, the utility model comprises an adjustable connector 1 and two clamping bodies 2 arranged opposite to each other, both of the clamping bodies 2 are provided with connection holes 3 cooperating with the adjustable connector 1, the adjustable connector 1 is connected to the two connection holes 3, both of the inner sides of the two clamping bodies 2 are provided with arc-shaped clamping grooves 5, the front end of the clamping body 2 is thin, narrow and flat, and the rear ends of the two clamping bodies 2 are provided with handles 6. Specifically, the arc-shaped clamping groove 5 can be matched with the outside of the connecting steel ring to improve the stability of clamping; the front end of the clamping body 2 in a thin, narrow and flat shape can be extended into the connection gap between the connecting steel ring and the pipe to pry the too firm connecting steel ring to loosen it, so as to facilitate disassembly; at the same time, the front end of the clamping body 2 in a thin, narrow and flat shape can also be used to disassemble the screws with a slotted shape.

[0022] With respect to the deficiencies of the prior art, in the present invention, the front end of the narrow and flat clamping body 2 is extended into the connection gap between the connecting steel ring and the pipe so as to pry the overly firm connecting steel ring to loosen it, and the relative distance between the two clamping bodies 2 is further adjusted by adjusting the connecting piece 1, so that the two arc-shaped clamping grooves 5 can respectively fit the upper and lower ends of the connecting steel ring to be disassembled to adapt to the connecting steel ring, which can not only stabilize the connecting steel ring, but also prevent the two clamping bodies 2 from shaking during subsequent disassembly and damaging the pipelines on both sides of the connecting steel ring and other metal scratches. The two handles 6 are further pushed to push the connecting steel ring in the disassembly direction to complete the disassembly. Therefore, the present invention can improve work efficiency and is simple to operate, so that the operator can reduce the work intensity, and the production and manufacturing are relatively easy and low-cost, so that the present invention has the advantages of easy disassembly and easy operation.

[0023] It should be noted that the disassembly device is placed as a whole on one side of the connecting steel ring to be disassembled during disassembly. After the connecting steel ring is clamped by two arc-shaped clamping grooves 5, the disassembly of the connecting steel ring is achieved by pushing the two handles 6.

[0024] In some embodiments, the handle 6 is threadedly connected to the clamping body 2; the front end of the handle 6 is provided with a straight-line threaded connection portion 7, and the clamping body 2 is provided with a threaded hole 8 that cooperates with the threaded connection portion 7; and the handle 6 is provided with an anti-slip protrusion 9. Specifically, the handle 6 is threadedly connected to the clamping body 2, so that the handle 6 can be removed separately, and the straight-line threaded connection portion 7 at the front end of the handle 6 can be used to pry and fix the extremely strong connecting steel ring and objects, and can also be used to remove the straight-lined screws of suitable size; in addition, the anti-slip protrusion 9 can increase the friction when holding the hand to prevent sliding.

[0025] In some embodiments, an anti-skid pad 10 is provided on the inner side of the clamping body 2. Specifically, the anti-skid pad 10 is made of rubber; when the clamping body 2 is clamped, the anti-skid pad 10 contacts the connecting steel ring, which can not only effectively buffer and prevent the connecting steel ring from sliding and falling off, but also protect the connecting steel ring that needs to be disassembled, and prevent damage to the connecting steel ring and other surrounding metal parts.

[0026] In some embodiments, the adjustable connector 1 is a columnar structure, and the threaded connection portion 7 is disposed perpendicular to the adjustable connector 1 .

[0027] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
