[0021] refer to Figure 2 and Figure 3 The positioning mechanism 8 includes a load-bearing block 801, two compression springs 802, two vertical blocks 803 and two insertion rods 804. The load-bearing block 801 is fixedly connected to the front side of the inner wall of the cavity 7. The two compression springs 802 are respectively fixedly connected to the left and right sides of the load-bearing block 801.

The tops of the two vertical blocks 803 are fixedly connected to two connecting columns 10, which are used in conjunction with the adjustment mechanism 9.

[0022] By adopting the above solution, by providing the positioning mechanism 8 , the connecting block 5 can be fixed by the clamping block 4 , so that the protective plate 3 is fixed to the front side of the interface end 2 to prevent dust from entering the interface end 2 .

[0023] refer to Figure 4 The adjusting mechanism 9 includes a pulling rod 901, a connecting plate 902, two pushing columns 903, two circular shafts 904 and two connecting rods 905. The pulling rod 901 is fixedly connected to the top of the connecting plate 902. The top of the pulling rod 901 passes through and extends out of the surface of the clamping block 4. The two pushing columns 903 are respectively fixedly connected to the left and right sides of the top of the connecting plate 902. The two circular shafts 904 are respectively fixedly connected to the two sides of the inner wall of the cavity 7. The two connecting rods 905 are respectively rotatably connected to the surfaces of the two circular shafts 904.

The sides of the connecting rods 905 close to the connecting column 10 are sleeved on the surface of the connecting column 10.

[0024] The above solution is adopted: by providing the adjustment mechanism 9, it is convenient for the user to flip the protection plate 3 to expose the interface end 2, and then the interface end 2 can be connected to other instruments.

[0025] refer to Figure 4 A transmission hole 11 is opened on the surface of the connecting rod 905, and the inner wall of the transmission hole 11 contacts the surface of the connecting column 10.

[0026] By adopting the above solution, the transmission hole 11 is provided, so that the linkage between the connecting rod 905 and the connecting column 10 can be improved, so that the movement of the connecting rod 905 drives the connecting column 10 to move.

The side of the limiting rod 12 close to the vertical block 803 penetrates the surface of the vertical block 803 and is fixedly connected to the other side of the inner wall of the cavity 7.

[0028] By adopting the above solution, the limiting rod 12 is provided to limit the movement of the vertical block 803, thereby preventing the vertical block 803 from being offset during movement.

[0029] refer to Figure 4 The bottom of the inner wall of the cavity 7 is fixedly connected to two slideways 13 , and the bottom of the connecting plate 902 is fixedly connected to two support columns 14 , which are slidably connected to the surface of the slideways 13 .

[0032] By adopting the above solution, the anti-sliding block 15 is provided, so that the friction between the tester 1 and the palm of the user can be increased, thereby preventing the tester 1 from being too smooth.

[0033] When in use, the pulling rod 901 is pulled to the front side, and the pulling rod 901 drives the connecting plate 902 and the two pushing columns 903 to move to the front side when moving. The two pushing columns 903 squeeze the surfaces of the two connecting rods 905 when moving, so that the two connecting rods 905 rotate clockwise and counterclockwise around the surfaces of the two circular shafts 904 respectively. After the two connecting rods 905 move, they squeeze the surface of the connecting column 10 through the inner wall of the transmission hole 11, so as to drive the two connecting columns 10 to move toward the side close to each other. When the two connecting columns 10 move, they drive the two vertical blocks 803 to move toward the side close to each other. When the two vertical blocks 803 move, they squeeze the two compression springs 802. When the vertical block 803 moves, it drives the insertion rod 804 to enter the interior of the cavity 7. At this time, the protective plate 3 can be flipped over to expose the interface end 2.
