By setting a locking rod 44, the locking rod 44 is rotatably connected to the first protruding portion 411, and the slot 4121 provided in the second protruding portion 412 has a clearance opening away from the clamping hole 46. The locking rod 44 can be rotated to be clamped into the slot 4121 from the clearance opening, and then the locking nut 45 is tightened to make the locking nut 45 abut against the second protruding portion 412, so that the two clamping portions are connected to form the clamping hole 46 at one end away from the rotating shaft 43. When the clamping hole 46 needs to be opened, the locking nut 45 is loosened, and the locking rod 44 is rotated to make the locking rod 44 escape from the clearance opening and the slot 4121. In addition, since the first protruding portion 411 is provided with a positioning protrusion 4111 on the side facing the second protruding portion 412, the positioning protrusion 4111 can cooperate with the slot 4121 to play a positioning role when the two clamping members 41 are closed, so as to prevent the two clamping members 41 from being relatively deformed along the axial direction of the clamping hole 46 to form an angle.

[0056] Preferably, the other end of the pull rod 42 away from the clamping member 41 is connected to a U-shaped clip 421, and the opening width of the U-shaped clip 421 corresponds to the thickness of the pressing plate 31. When the pulling assembly 40 and the pressing plate 31 are installed, the U-shaped clip 421 can be clamped to the outer periphery of the pressing plate 31.

[0057] The auxiliary disassembly and assembly device of the utility model can assemble and disassemble the back tube and the extension piece. When the extension piece needs to be installed on the back tube, the second base is first installed on the first base, the back tube is placed in coordination with the supporting parts of the second base, and one end of the back tube away from the pressing plate abuts against the abutment piece, and then the hydraulic pump is controlled to reduce the pressure on the driving piece so that the telescopic end of the driving piece contracts and drives the pressing plate to move in the direction close to the abutment piece, so that the extension piece is pressed tightly into the end of the back tube; when the extension piece needs to be taken out from the back tube after the target material is cast, the second base is first removed from the back tube, and the second base is removed from the back tube. The first base support is removed, and then the target material is placed in the first supporting groove of the first base support, and each top cover member is installed one by one in coordination with each first base support to clamp the target material, and then the two clamping members are enclosed and clamped in the annular groove on the surface of the target material. At this time, the U-shaped clamp at the end of the pull rod is synchronously clamped to the outer periphery of the pressing plate, and then the hydraulic pump is controlled to increase the pressure on the driving member so that the telescopic end of the driving member extends to drive the push plate to move away from the fixed seat. At this time, the pressing plate moves with the push plate in the direction away from the abutment member, and the pulling assembly pulls the extension member out of the back tube.

[0058] In summary, the embodiments of the utility model provide an auxiliary disassembly and assembly device, which does not require manual knocking to disassemble and assemble the extension piece. Instead, a driving member drives a pressing plate to press and assemble the extension piece to a back tube, or a driving member drives a pressing plate to drive a pulling assembly to pull the extension piece out of the back tube, which greatly saves manpower and time costs and will not damage the target material product.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
