[0019] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.

[0020] As Figures 1-4 shown, the present utility model provides a technical solution: a wire harness airtightness test device, including the main body 1 of the test device. Since the four corners of the main body 1 of the test device are designed as arc surfaces, it prevents the main body 1 of the test device from scratching the user and improves safety. A protective cover 3 is hinged on the main body 1 of the test device. A rotating rod 5 is fixedly connected to the protective cover 3. One end of the rotating rod 5 is fixedly connected to a turntable 11. A first handle 4 is fixedly connected to one side of the protective cover 3. Since there is a first handle 4, the first handle 4 provides a holding point, which is convenient for personnel to hold the first handle 4 to rotate the protective cover 3 and improves the operation convenience. A groove 6 is opened on the main body 1 of the test device.

[0021] A first circular groove 17 is opened on the turntable 11, and a second circular groove 18 is opened on the turntable 11. Due to the arc surface design of the first circular groove 17 and the second circular groove 18, it is convenient to push the hemisphere 14, thus facilitating the smooth progress of subsequent operations. A box body 2 is fixedly connected to the main body 1 of the test device. A movable rod 12 is slidably connected to the box body 2. A spring 16 is sleeved on the movable rod 12.
