[0030] In a preferred embodiment provided in this application, the base 1 has three control buttons 10 on one side for controlling the motor 6 to start, pause and stop. A housing 2 is provided on the upper surface of the base 1. The housing 2 is composed of an upper surface and three consecutive side surfaces, wherein on the side facing the control buttons 10, the side surface of the housing 2 is replaced by a first opening 21.

[0031] Inside the housing 2, a rectangular box 3 is provided at the center of the upper end face of the base 1. The upper end face of the box 3 is symmetrically provided with two first grooves 31, both of which are adapted to the shape of the key body 9. The box 3 is fixed to the base 1 by a detachable bolt connection. Both the box 3 and the base 1 are provided with holes suitable for bolt connection.

[0032] A cover 4 with the same shape as the box 3 is provided on the upper end face of the box 3. Two second grooves 41 are symmetrically provided on the lower end face of the cover 4. Both second grooves 41 are adapted to the shape of the key body 9. When the cover 4 is placed on the box 3, the first groove 31 and the second groove 41 form a cavity 8 with the same shape as the key body 9. The cover 4 is fixed to the plate 5 by a detachable bolt connection. Both the cover 4 and the plate 5 are provided with holes suitable for bolt connection.

[0033] A reciprocating telescopic motor 6 is provided on the upper end face of the housing 2. The upper end face of the housing 2 is provided with a through hole. The moving end of the motor 6 can reciprocate inside the housing 2. The motor 6 can be a reciprocating telescopic motor 6 in the prior art, such as "57 through-type linear screw stepper motor 6".

[0034] Inside the housing 2, a plate 5 is fixed at the top of the moving end of the motor 6. The plate 5 is a flat cuboid. The cross-section of the plate 5 in the horizontal direction is larger than the cross-section of the box 3 and the cover 4.

[0035] Four first rods 7 are provided at the four corners of the upper end face of the plate 5. The four first rods 7 are all set parallel to the movement direction of the moving end of the motor 6. Four first holes 22 are provided on the upper end face of the housing 2 for the first rods 7 to pass through. When the motor 6 drives the plate 5 to move up and down in the housing 2, the four first rods 7 move up and down synchronously in the four first holes 22. The length of the first rods 7 is greater than the distance between the upper end face of the base 1 and the upper end face of the housing 2.

[0036] During use, the operator starts the motor 6 to move upward by controlling button 10, separating the cover 4 from the box 3. The key body 9 is then placed into the first slot 31 through the first opening 21. Then, the operator starts the motor 6 to move downward by controlling button 10, connecting the cover 4 to the box 3 and enclosing the key body 9 in the cavity 8 formed by the combination of the first slot 31 and the second slot 41. After that, the operator waits for the testing program to proceed. After the testing program is completed, the operator starts the motor 6 to open the cover 4 upward and remove the key body 9, allowing for quick and repeated airtightness testing.

[0037] In this embodiment, by setting a motor 6 on the housing 2 to drive the plate 5 to move up and down inside the housing 2, the rapid separation and assembly of the cover 4 and the housing 2 are realized, which improves the efficiency of installing samples in the airtightness test of the housing, and the simple structure is easy to manufacture.
