Description

Technical Field

[0001] The utility model relates to the technical field of aerospace, in particular to a novel wrench. Background Art

[0002] There are basically two types of wrenches, fixed wrenches and adjustable wrenches. The former refers to wrenches with fixed numbers written on them, while the latter is an adjustable wrench. 1. Fixed wrench: One or both ends are made with an opening of fixed size, used to turn nuts or bolts of a certain size. 2. Plum wrench: Both ends have working ends with hexagonal holes or twelve-pointed holes, suitable for occasions where the working space is small and ordinary wrenches cannot be used. 3. Two-purpose wrench: One end is the same as a single fixed wrench, and the other end is the same as a plum wrench, and both ends turn bolts or nuts of the same specifications. 4. Adjustable wrench: The opening width can be adjusted within a certain size range, and can turn bolts or nuts of different specifications. The structural characteristics of this wrench are that the fixed jaws are made into flat jaws with fine teeth; one end of the movable jaws is made into a flat jaw; the other end is made into a concave jaw with fine teeth; by pressing the worm down, the movable jaw can be quickly removed and the jaw position can be changed. 5. Hook wrench: also known as a crescent wrench, used to turn flat nuts with limited thickness, etc. 6. Socket wrench: It is composed of multiple sockets with hexagonal holes or dodecagonal holes and equipped with a variety of accessories such as handles and connecting rods. It is particularly suitable for turning bolts or nuts in very narrow positions or deep recesses. 7. L-shaped hexagonal bar wrench, specially used for turning hexagon socket screws. The model of the hexagon socket wrench is based on the size of the opposite sides of the hexagon, and the size of the bolt has national standards. Uses: Specially used for tightening or disassembling round nuts on machine tools, vehicles, and mechanical equipment. 8. Torque wrench: It can display the applied torque when turning bolts or nuts; or when the applied torque reaches the specified value, it will emit a light or sound signal. Torque wrenches are suitable for equipment with clear regulations on torque size.

[0003] With the extensive use of circular electrical connectors in aerospace, the installation of electrical connector tail accessories is generally done manually by operators during the ground wiring harness production process, which is time-consuming and laborious, and the installation is not reliable enough. Especially when installing electrical connector tail accessories on an aircraft or spacecraft, the installation work is very difficult due to the limitation of working space. Therefore, it is urgent to design a new type of wrench to replace manual operation.

[0004] The new wrench is an original structure, mainly used for the installation and removal of the rear accessories of circular electrical connectors. Its notable feature is that it can quickly realize the clamping, positioning, installation and removal of the rear accessories of electrical connectors. Utility Model Content
