It should be noted that in this application, where the context requires no explicit mention, the use of directional terms such as "upper, lower, top, bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in a vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

According to the figure 1, the oil cup to be disassembled comprises an oil cup 1 made of glass and a flange 2, and a connecting hole 3 is formed in the flange 2.

According to fig. 2, the transformer respirator oil cup detacher comprises a base 4, positioning columns 5, a connecting plate 6 and a clamping piece 7, wherein the positioning columns 5 and the connecting plate 6 are fixedly connected to two opposite sides of the top of the base 4 respectively, a clamping claw 8 is arranged at the left end of the clamping piece 7, a handle 9 is arranged at the right end of the clamping piece, a screw rod 10 is arranged in the middle of the clamping piece and is in threaded connection with the connecting plate 6, and the screw rod 10 is rotatably connected with the clamping claw 8.

According to the figures 3 and 4, in specific use, the positioning column 5 is inserted into the connecting hole 3 in the oil cup flange 2 of the transformer respirator, the handle 9 is rotated, the clamping jaw 8 is pushed to the oil cup flange 2, the clamping jaw 8 and the positioning column 5 clamp the oil cup flange 2 at the moment, the handle 9 is rotated anticlockwise, the oil cup flange 2 is detached along with the rotation of the handle 9, the middle of the clamping part 7 is in threaded connection with the connecting plate 6 through a screw rod, the distance between the clamping jaw 8 and the positioning column 5 can be adjusted through rotating the handle 9, and the problem that the oil cup detachers of the transformer respirators with different sizes in the prior art cannot be used universally is solved through the structural design.

Specifically, base 4 is rectangle structure one, and the welding of reference column 5 is in 4 top left sides of base to be level with the left surface of base 4, connecting plate 6 is rectangle structure two, welds on 4 top right sides of base, and is level with the right surface of base 4, is equipped with the screw hole on the connecting plate 6, and the screw thread in the screw hole is self-locking thread.
