[0013] The beneficial effects in the application are:

[0014] 1. By setting the fixed frame, the No. 2 hydraulic cylinder, the ejection block, the extrusion sheet, the wiping fiber plate and the arc-shaped wiping protrusion, when the generator set is clamped by the clamping ring, the No. 2 hydraulic cylinder drives the multiple extrusion sheets on the ejection block to contact the wiping fiber plate, so that the wiping fiber plate is ejected, the wiping fiber plate is in close contact with each face of the generator set, at the same time, the arc-shaped wiping protrusion on the film slides into each concave point on the generator set, when the wiping fiber plate is wiped by adjusting the No. 1 hydraulic cylinder, the wiping fiber plate and the arc-shaped wiping protrusion are in close extrusion contact with each convex surface and concave surface of the generator set, perfect wiping is realized, and the stability during the clamping process of the generator set by the clamping ring is ensured.

[0015] 2. By setting the multiple extrusion assemblies, the multiple extrusion assemblies are composed of multiple extrusion plates, extrusion springs are distributed at equal distances between each extrusion plate, when the generator set is clamped by the clamping ring, the gravity of the generator set on the position below the clamping ring is the largest, the multiple extrusion assemblies are located close to the lowermost position of the clamping ring, the gravity causes the extrusion springs between each extrusion plate to be infinitely compressed until the critical point, at this time, the potential energy of the rebound of the extrusion spring drives the extrusion plate to be in close contact with the generator set, complete clamping support is realized, within the limited range, the greater the weight of the generator set, the greater the extrusion force of the multiple extrusion assemblies at the contact point, and the more stable the clamping of the generator set.

[0016] 3. By setting up bottom support plates and friction plates, when the generator set is supported at both ends, the friction plates on the bottom support plates are in contact with the bottom end of the generator set. The friction plates on the same bottom support plate are distributed in regions, and the friction direction of the friction plates in each region is pointing towards the center end of that region. This makes the friction plates in each region on the bottom support plate form independent arc-shaped friction ranges, increasing the friction force on the outer wall of the generator set from each region and improving its stability when supported at both ends.

[0017] 4. By incorporating a buffer assembly consisting of a placement plate, a support, a buffer spring, and a guide rail, the generator set is protected from the potential safety hazard of falling during hoisting. When the generator set falls from the clamping ring, it impacts the placement plate. The support below the placement plate causes the buffer spring to slide along the inner wall of the guide rail, thus buffering the impact force of the falling generator set and protecting it. At the same time, it also provides safety protection for nearby personnel.

[0018] 5. By setting up uprights and suction cups, the uprights are distributed in a stepped manner on the placement plate, and each upright is equipped with a suction cup. When the generator set falls and hits the placement plate, the stepped suction cups will adhere to the various outer surfaces of the generator set, improving its stability after falling onto the placement plate and preventing it from shaking significantly.

[0019] 6. By incorporating a dual buffer assembly, when the generator set placed on the mounting plate is cushioned, the mounting plate compresses the pressure plate below, and the hydraulic damper below the pressure plate is also compressed. This causes the mounting plate to gradually come into contact with the pressure plates on each step, achieving progressive cushioning and shock absorption. When the hydraulic damper below each pressure plate is compressed to the critical point, the first buffer plate compresses the buffer airbag below. After the buffer airbag is compressed to the critical point, the spring rod is also compressed. Through the cooperation of this dual buffer assembly with the buffer assembly below the second buffer plate, triple cushioning is achieved, improving the cushioning effect of this maintenance tool.
