When the 8 indicator function areas rotate to the position directly aligned with the position indicated by the push indicator board 4032, it means that the output port test base plate 3 can be pushed out when the push action is performed at this time.

[0112] When the push indicator board 4032 points to the first indicator function area 40311, it represents that the pressing transmission output member 404 can drive the middle test base plate 31, the upper test base plate 32, and the lower test base plate 33 to move.

[0113] When the push indicator board 4032 points to the second indicator function area 40312, it represents that the pressing transmission output member 404 can drive the middle test base plate 31 to move.

[0114] When the push indicator board 4032 points to the third indicator function area 40313, it represents that the pressing transmission output member 404 can drive the middle test base plate 31 and the lower test base plate 33 to move.

[0115] When the push indicator board 4032 points to the fourth indicator function area 40314, it represents that the pressing transmission output member 404 can drive the middle test base plate 31, the upper test base plate 32, and the lower test base plate 33 to move.

[0116] When the push indicator board 4032 points to the fifth indicator function area 40315, it represents that the pressing transmission output member 404 can drive the middle test base plate 31, the upper test base plate 32, and the lower test base plate 33 to move.

[0117] When the push indicator board 4032 points to the sixth indicator function area 40316, it represents that the pressing transmission output member 404 can drive the middle test base plate 31 to move.

[0118] When the push indicator board 4032 points to the seventh indicator function area 40317, it represents that the pressing transmission output member 404 can drive the middle test base plate 31 and the upper test base plate 32.

[0119] When the push indicator board 4032 points to the eighth indicator function area 40318, it represents that the pressing transmission output member 404 can drive the middle test base plate 31, the upper test base plate 32, and the lower test base plate 33 to move.

[0120] Preferably, each of the eight indicating functional areas includes three rows of indicating marks, which respectively indicate the upper test bottom plate 32, the middle test bottom plate 31, and the lower test bottom plate 33 from the outside to the inside. Among them, "one shape" means that the corresponding test plate can be pushed out, and "..." means that the corresponding test plate cannot be pushed out.

[0121] Preferably, as Figure 19 and Figure 20 shown, the rotary directional pushing member 405 includes a rotary support member 4051, a first turntable 4052, a pushing input handle 4053, a pushing transmission handle 4054, a second round-grooved turntable 4055, and a central guide rod 4056; one side of the first turntable 4052 is fixedly connected to the rotary support member 4051, and the other side of the first rotation is fixedly connected to the central guide rod 4056. Eight fourth hinge rods are circumferentially and evenly distributed on the first turntable 4052. The first turntable 4052 is hinged to the pushing input handle 4053 through the fourth hinge rod. The central guide rod 4056 is sleeved with the second round-grooved turntable 4055. Eight fifth hinge rods are circumferentially and evenly distributed on the second round-grooved turntable 4055. The second round-grooved turntable 4055 is hinged to the pushing transmission handle 4054 through the fifth hinge rod. The middle part of the pushing input handle 4053 is hinged to the pushing transmission handle 4054 through a sixth hinge rod.

[0122] When pushing the pushing input handle 4053, pushing the pushing input handle 4053 drives the second round-grooved turntable 4055 to push forward through the pushing transmission handle 4054, thereby realizing the pushing out of the first-stage transmission round rod 4041.

[0123] Preferably, a fixed connection is provided between the second round-grooved turntable 4055 and the first-stage transmission round rod 4041.

[0124] Preferably, as Figure 21 shown, a sliding connection is provided between the central guide rod 4056 and the first circular groove 4042.

[0125] Preferably, when the pushing input handle 4053 completes the pushing-out action, the lengths of the fourth hinge rod and the fifth hinge rod from the center line of the central guide rod 4056 are greater than the length of the sixth hinge rod from the center line of the central guide rod 4056.

[0126] When the lengths of the fourth hinge rod and the fifth hinge rod from the center line of the central guide rod 4056 are greater than the length of the sixth hinge rod from the center line of the central guide rod 4056, the sixth hinge rod abuts against the central guide rod 4056 under the action of the compression spring 4044, realizing the self-locking of the rotary directional pushing member 405.

[0127] Preferably, asFigure 22 As shown, the rotating support member 4051 includes a rotating support shaft 40511, a rotating support bearing seat 40512, a spring ball pin 40513 and a round pin hole 40514; the rotating support shaft 40511 and the rotating support bearing seat 40512 are rotatably connected, 8 evenly distributed spring ball pins 40513 are installed in the rotating support shaft 40511, and 8 evenly distributed round pin holes 40514 are opened in the rotating support bearing seat 40512.

[0128] The arrangement of the round pin hole 40514 and the spring ball pin 40513 enables the operator to easily align the eight indicating function areas with the pushing indicating plate 4032 when turning the pushing input handle 4053 .
