Both the fixed striking head seat 4072 and the movable striking head seat 4071 are provided with a second threaded hole 408. The fixing bolt passes through the fixed striking head seat fixing hole 4061 and the second threaded hole 408 in sequence to fix the fixed striking head seat 4072 to the striking head. On the adjusting plate 406, the fixing bolts pass sequentially through the movable strike head seat movable groove 4062 and the second threaded hole 408 to fix the movable strike head seat 7041 onto the adjusting plate 406. When the fixing bolts are screwed into the second threaded hole 408, and the threaded head is not locked to the movable strike head seat movable groove 4062, the interval between the movable strike head seat movable groove 4062 and the fixed strike head seat fixing hole 4061 can be changed by adjusting the relative position of the fixing bolts within the movable strike head seat movable groove 4062. In a specific embodiment of this utility model, the interval between the movable strike head seat movable groove 4062 and the fixed strike head seat fixing hole 4061 corresponds to the interval between the first and second rows of the keyboard under test (the default order is from top to bottom).

[0042] Reference Figure 7a The keycap 407 (including the fixed keycap 4072 and the movable keycap 4071) is equipped with keycap components 409. The fixed keycap 4072 includes five keycap components 409 with equal spacing, which are used to detect keystrokes on the second to sixth rows of the keyboard under test. The movable keycap 4071 includes one keycap component 409, which is used to detect keystrokes on the first row of the keyboard under test.

[0043] Reference Figure 7aThe striking assembly 409 includes an electromagnet core 4091 mounted on a striking head base 407. An electromagnet 4092 is fitted around the electromagnet core 4091. When the electromagnet 4092 is energized, a magnetic field is generated around it, causing the electromagnet core 4091 to move upward under the influence of the magnetic field. A weight 4093 is mounted above the electromagnet core 4091. In this specific embodiment, the weight 4093 is preferably 25g. When the top of the electromagnet core 4091 is fixedly connected to the bottom of the weight 4093, the electromagnet core 4091 drives the weight 4093 to move upward together. A through hole 4094 is provided on the rear side of the weight 4093. A guide rod 4095 is provided through the inner wall of the through hole 4094. The guide rod 4095 is used to adjust the direction of movement of the electromagnet core 4091 and the weight 4093, ensuring that their direction of movement is always vertically upward along the guide rod 4095. A striking rod 4096 is fixedly connected to the front side of the weight 4093. A striking rod guide sleeve 4073 is provided inside the striking head seat 407. The bottom of the striking rod 4096 passes through the bottom of the striking head seat 407 along the direction of the striking rod guide sleeve 4073. When the weight 4093 moves vertically upward along the guide rod 4095, it drives the striking rod 4096 to move vertically upward along the striking rod guide sleeve 4073.

[0044] Reference Figure 7a A weight plate 4051 is positioned above the weight 4093. Both ends of the weight plate 4051 are fixed to the second striking head base fixing plate 405. The weight 4093 moves vertically upward along the guide rod 4095 until it abuts against the weight plate 4051. At this point, the weight 4093, the striking rod 4096, and the electromagnet core 4091 stop moving vertically upward. Then, the electromagnet 4092 is de-energized, the magnetic field disappears, and the weight 4093 moves vertically downward along the guide rod 4095 under the influence of gravity. This causes the electromagnet core 4091 to move vertically downward, and the striking rod 4096 to move vertically downward along the striking rod guide sleeve 4073. An annular protrusion 4097 is provided on the electromagnet core 4091. The electromagnet core 4091 moves vertically downward until the annular protrusion 4097 abuts against the electromagnet 4092; the weight 4093 drives the striking rod 4096 and the electromagnet core 4091 to stop moving vertically downward.

[0045] In summary, the weight 4093 and the electromagnet core 4091 can move vertically up and down along the guide rod 4095, which in turn drives the striking rod 4096 to move vertically up and down along the striking rod guide sleeve 4073.

[0046] As a preferred embodiment of this utility model, refer to Figure 7a The bottom of the key stick 4096 is provided with a key contact 4098. When the key stick 4096 strikes the keyboard up and down, the key contact 4098 can reduce the mechanical wear caused to the keyboard under test by the keying test.

One end of each vision inspection support rod 601 is vertically fixed to the base plate 1. A vision inspection fixing frame 602 is vertically mounted between the other ends of the two vision inspection support rods 601. The vision inspection fixing frame 602 includes two main fixing rods 608 vertically connected to the vision inspection support rods 601 and two secondary fixing rods 607 connecting the same ends of the two main fixing rods 608. A third slide rail 603 is provided between the two secondary fixing rods 607 and slides back and forth along the secondary fixing rods 607. The third slide rail 603 is provided with a fourth slide rail 604 that slides left and right along the third slide rail 603. The fourth slide rail 604 is provided with a camera fixing block 605 that slides up and down along the fourth slide rail 604. A camera 606 is fixed on the camera fixing block 605. The camera 606 can slide up and down along the fourth slide rail 604 with the camera fixing block 605. Driven by the fourth slide rail 604, the camera can slide left and right along the third slide rail 603 with the fourth slide rail 604. Driven by the third slide rail 603, the camera can slide back and forth along the third slide rail 603 along the secondary fixing rod 607.

[0048] The light sensor of camera 606 is facing the linear module 2. When the keyboard under test moves along the linear module 2 below camera 606, camera 606 is controlled to take a picture of the keyboard under test.
