[0002] After a period of flight operation, the E190 aircraft must perform necessary cleaning of the condenser heating air in accordance with established maintenance requirements in order to maintain its efficient and stable performance. This step is crucial because it is directly related to the normal operation of the aircraft air conditioning system and the comfort of passengers. Before cleaning, the first task is to disassemble the condenser from the entire air conditioning assembly.

[0003] Since the condenser is a complex component and in order to ensure that it is thoroughly repaired and maintained, it is usually necessary to send it to a specialized repair center for separate repair. During the disassembly process, special care must be taken because there are many other accessories connected to the condenser, among which the interconnecting pipe is a particularly critical component. The connection between it and the condenser adopts a precise design, including external sleeves and nuts. This connection method not only ensures a tight connection between the pipe and the condenser, but also allows the coolant to flow smoothly. However, it is precisely because of the particularity of this design that special tools must be used when disassembling the interconnecting pipe.

[0004] Traditional disassembly tools are often designed to damage components during operation, which not only shortens the service life of the components but also may cause a series of safety hazards. In addition, traditional tools are complex to operate and inefficient, which greatly affects the progress of aircraft maintenance. Summary of the invention

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1 and 2 As shown, the utility model comprises a wrench body, wrench teeth 4 and an adjustment mechanism 3.

[0021] The wrench body comprises a wrench handle 1 and a wrench head 2. The wrench handle 1 is fixedly connected to the wrench head 2. The wrench head 2 is in an arc shape, and the shape of the nut thereof corresponds to that of the wrench head 2.

[0022] The wrench head 2 is provided with a cavity with openings on both sides, and the cavity is arranged along the arc-shaped structure of the wrench head 2. Two arc-shaped through holes are respectively provided on the two end walls of the wrench head 2. The two arc-shaped through holes are arranged concentrically, and the arc-shaped through holes correspond to the arc-shaped structure of the wrench head 2 and are connected to the cavity.

[0023] like Figures 3-5 As shown, the cavity of the wrench head 2 is provided with an adjustment mechanism 3, which includes a sliding plate 301, a positioning pin 302 and a bidirectional lead screw 304. The sliding plate 301 is provided with two strip-shaped through holes, and the inner end of the sliding plate 301 is provided with a square blind hole, in which a wrench tooth 4 is inserted. The outer end of the sliding plate 301 is provided with a rotating blind hole, which is connected with the two strip-shaped through holes. The bidirectional lead screw 304 is installed in the rotating blind hole, and the inner end of the bidirectional lead screw 304 is rotatably matched with the bottom of the rotating blind hole. A positioning pin 302 is installed in each strip-shaped through hole of the sliding plate 301, and a threaded through hole is provided in the middle part of the positioning pin 302. The outer wall of the positioning pin 302 is fitted with the inner wall of the strip-shaped through hole, and the threads at both ends of the bidirectional lead screw 304 are respectively threadedly matched with the threaded through holes of the corresponding positioning pin 302. When the bidirectional lead screw 304 rotates, the two positioning pins 302 can move symmetrically.

[0024] The walls opposite to the two arc-shaped through holes of the wrench head 2 are provided with a plurality of circularly distributed positioning holes, the positioning holes on the two arc-shaped through holes correspond to each other, and both ends of the positioning pin shaft 302 pass through the strip-shaped through holes of the sliding plate 301 and are placed in the positioning holes to fix the sliding plate 301.

[0025] In the optimization scheme, the outer end of the bidirectional lead screw 304 is fixedly connected to the operating head 303. The outer end of the operating head 303 is provided with a hexagonal blind hole. Inserting a hexagonal wrench into the operating head 303 can rotate the operating head 303 and drive the bidirectional lead screw 304 to rotate.

[0026] A square blind hole is provided inside the rear end of the wrench head 2, and a wrench tooth 4 is inserted into the square blind hole.

[0027] In the optimized solution, a magnet is installed at the bottom of the square blind hole, and a magnet with opposite magnetic properties is provided at the tail end of the wrench tooth 4, so that the wrench tooth 4 can be adsorbed in the square blind hole.

[0028] The operation process is as follows: when using this device, by rotating the bidirectional screw 304, the bidirectional screw 304 drives the two positioning pins 302 to disengage from the positioning through holes of the wrench head 2. At this time, the position of the sliding plate 301 can be adjusted at will within the range of the cavity of the wrench head 2. When the sliding plate 301 is adjusted to the specified position, rotate the bidirectional screw 304 so that the wrench teeth 4 on the sliding plate 301 are inserted into the grooves on the corresponding nut, fix the tightening nut, and disassemble the external sleeve and nut.

[0029] It should be noted that the specific embodiments of the present invention have been described in detail.
