[0028] In this embodiment, Figure 2 As shown, the gear 103 is in a rotating structure through the servo motor 102, and the first movable seat 101 forms a transmission structure inside the first base 1 through the gear 103 and the rack 104, and the inner wall of the first base 1 and the inner wall of the second base 2 are both provided with a slide groove, and the first movable seat 101 slides inside the groove through the first limit block 105, and a mounting frame is fixed below the servo motor 102, and a pulley is provided below the mounting frame; the gear 103 is rotated by the servo motor 102 to transmit on the surface of the rack 104, which can drive the upper adjustment component 3 to reciprocate to replace the manual back and forth sliding of the detection element 5, which can not only achieve the effect of automated detection, but also the internal transmission structure of the first base 1 can reduce the possibility of displacement of the detection element 5 during the transmission process.

[0030] In this embodiment, Figure 5 As shown, the column 301 is threadedly connected to the adjusting screw 302, and the clamping member 303 forms a movable structure with the column 301 through the adjusting screw 302; due to the uncertainty of the specifications of the detection object, in order to facilitate the fixing of the position of the detection element 5, the position of the clamping member 303 is moved by adjusting the screw 302, so that the clamping members 303 can present adjustment structures of different distances for clamping at both ends of the detection object, thereby improving the use range of the device and making the clamping width not limited.
