All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1, the pneumatic press-fit jig of the utility model comprises a base 9, wherein a power device and three sliding parts 10 for loading a detection element 11 are arranged on the base 9, the power device and the sliding parts 10 are rotatably connected through a push rod assembly, the three sliding parts 10 are arranged right in front of the push rod assembly, the other two sliding parts are symmetrically arranged relative to the push rod assembly, and according to different tested products, the detection element can be placed on different sliding parts 10, and the power device pushes the push rod assembly to drive the sliding block to reciprocate. In the actual production, the single-die movement module 13 is installed on the jig and is matched with the jig for use. Since the single-mode motion module 13 belongs to the prior art and is not within the protection scope of the present invention, it is not described in detail. The power means in this embodiment is preferably a cylinder 8, but other power means are also possible, such as a motor drive or the like. In addition, the test element in this embodiment is specifically a needle hub assembly, and the needle hub assembly is only mounted on the sliding member through a bolt, which is not within the protection scope of the present invention.

The push rod assembly in the embodiment comprises a first push rod 1, a second push rod 2, a third push rod 3 and a switching block 4, one end of the first push rod 1, one end of the second push rod 2 and one end of the third push rod 3 are connected with the switching block 4 in a rotating mode, the other end of the first push rod 1, the other end of the second push rod 2 and the other end of the third push rod 3 are respectively connected with three different sliding parts 10 in a rotating mode, and the other side of the switching block 4 is connected with a driving end of a power device. Specifically, one ends of the first push rod 1, the second push rod 2 and the third push rod 3 are overlapped together, a protrusion is formed on one side of the switching block 4, and the four connecting parts form rotary connection through a connecting rotating shaft. The transmission between the push rods is smoother through the switching block 4, and the stability is higher. In order to further improve the balance of the sliding part 10, the sliding parts 10 and the bottoms of the switching blocks 4 are provided with sliding blocks 5 which are arranged in pairs, and the base 9 is provided with a sliding rail 6 which is matched with the sliding blocks 5.
