Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a wire harness pipe joint disassembly device with high operating performance for aviation, comprising a handle 1, a telescopic rod 2 is inserted through one end of the handle 1, a fixing ring 3 is connected to one end of the telescopic rod 2, a fixing sleeve 4 is connected to both ends of the fixing ring 3, a screw rod 5 is threaded through one end of the fixing sleeve 4, and a pressure block 6 and a knob 7 are connected to both ends of the screw rod 5;

[0023] The outer wall of the handle 1 is connected to a mounting seat 9, a pull rod 10 is inserted through one end of the mounting seat 9, one end of the pull rod 10 is connected to a connecting block 11, one end of the connecting block 11 is connected to a latch 12, a spring 13 is sleeved on the outer wall of the pull rod 10, and a plurality of slots 14 are provided on the outer wall of the telescopic rod 2.

[0024] Preferably, two pressing blocks 6 are provided, and the two pressing blocks 6 are symmetrically distributed, and one end of the pressing block 6 is connected to a guide rod 8;

[0025] It should be noted that one end of the guide rod 8 extends through the outside of the fixing ring 3, and the guide rod 8 plays a guiding role in the movement of the pressing block 6, and an anti-slip pad can be provided on the contact surface between the pressing block 6 and the joint.

[0026] When in use, the screw rod 5 is rotated by the knob 7. Since the screw rod 5 and the fixing sleeve 4 are in a threaded connection structure, the pressing block 6 at one end of the screw rod 5 will move along the guide rod 8. Then, the two knobs 7 are rotated in the above manner so that the symmetrically distributed pressing blocks 6 clamp the joint and subsequent disassembly work can be carried out.

[0027] It should be noted that the sizes of connectors that the wrench can adjust to are relatively limited, so compared to traditional wrenches, the above structure can be used for disassembly operations of aviation wire harness connectors of more sizes.

[0028] Preferably, one end of the bayonet 12 is inserted into the interior of the handle 1, and the sizes of the bayonet 12 and the slot 14 are matched. The handle 1 can form an elastic snap-fit ​​structure with the telescopic rod 2 through the mounting seat 9, the pull rod 10, the connecting block 11, the bayonet 12, the spring 13, and the slot 14.

[0029] During specific use, the pull rod 10 is pulled to make the connecting block 11 drive the pin 12 to disengage from the slot 14, and then the telescopic rod 2 is extended and retracted according to the needs of the staff and then the pull rod 10 is released. At this time, the pin 12 will be reset under the action of the connecting block 11 and the spring 13, and inserted into the corresponding slot 14 to fix the telescopic rod 2 after extension and retraction, so that the length of the tool handle 1 can be conveniently adjusted.

[0030] Working principle: First, pull the pull rod 10 to make the connecting block 11 drive the pin 12 to disengage from the slot 14, then extend and retract the telescopic rod 2 according to the needs of the staff and then release the pull rod 10.

At this time, the screw rod 5 is rotated by the knob 7. Since the screw rod 5 and the fixing sleeve 4 are threaded connection structures, the pressure block 6 at one end of the screw rod 5 will move along the guide rod 8, and then the two knobs 7 are rotated in the above manner so that the symmetrically distributed pressure blocks 6 clamp the joint and subsequent disassembly work can be carried out. Compared with traditional wrenches, it can be suitable for more sizes of aviation wire harness pipe joint disassembly operations.
