[0033] Through the above embodiments, the storage structure 6 further includes an inner cavity 602, a sliding groove 603 and a fixing block 605. The inner cavity 602 is formed in the storage box 601, the sliding groove 603 is formed in the inner cavity 602 of the storage box 601, the sliding cover plate 604 is slidably installed in the sliding groove 603 of the storage box 601, and the fixing block 605 is fixed at the end position of the sliding cover plate 604. The adoption of the storage structure 6 facilitates the nearby storage of cables and is conducive to subsequent quick access and use.

[0034] It should be noted that after the detection terminal is purchased, each structure is in a separated state, and the detection instrument 4 is not installed in the housing 1. The system detection work of the payment device can be directly carried out using the detection instrument 4. When it is necessary to install the detection instrument 4 into the housing 1, first assemble the lifting and installation structure 3. During assembly, connect the lifting frame 304 with the clamping seat 305 to the first fixing plate 301 and the second fixing plate 302 respectively, so that the guide post 306 on the second fixing plate 302 is inserted into the through hole on the corresponding clamping seat 305. At the same time, ensure that the lower end of the adjusting screw 3074 in the adjusting frame 307 is threadedly connected to the fixing post 3071 on the first fixing plate 301. In this way, the installation and connection work of the fixing plate and the lifting frame 304 is completed. Then, place the first fixing plate 301 and the second fixing plate 302 in the lifting and installation structure 3 at the inner bottom end of the housing 1, and ensure that the holes on the two fixing plates are aligned with the connecting screw holes on the housing 1. Insert the installation bolt 303 into the holes on the fixing plate, and screw its end into the connecting screw hole to fix the first fixing plate 301 and the second fixing plate 302. After the two fixing plates are installed, at this time, the entire lifting and installation structure 3 is installed in the housing 1. Rotate the adjusting block 3075 in the adjusting frame 307, and the adjusting block 3075 drives the round bar 3072 at the clamping seat 305 to rotate. The round bar 3072 then drives the adjusting screw 3074 to rotate and rise on the fixing post 3071. Since the round bar 3072 in the adjusting frame 307 is arranged through the clamping seat 305, and at the same time, the support plates 3073 and the adjusting block 3075 at both ends of the round bar 3072 are in contact with the clamping seat 305, when the structures such as the adjusting screw 3074 rotate and rise, the lifting frame 304 and the clamping seat 305 will be driven through the support plate 3073, causing the lifting frame 304 to rise until the lifting frame 304 rises to a certain height. Subsequently, start installing the detection instrument 4. During installation, place the detection instrument 4 at the corresponding position on the lifting frame 304, and ensure precise alignment between the detection instrument 4 and the lifting frame 304. Then, screw on the fastening bolt 308 on the clamping seat 305 so that the fastening bolt 308 abuts against both ends of the detection instrument 4 to fix the detection instrument 4. After the detection instrument 4 is installed, install the protection structure 5. During installation, snap the fixing frame 501 with the first flexible strip 502 and the second flexible strip 503 onto the front and back surfaces of the detection instrument 4, and ensure the fixation of the fixing frame 501 through the clamping post 504, thereby completing the installation work of the protection structure 5. Then, place the detection instrument 4 into the housing 1. During operation, rotate the round bar 3072 by turning the adjusting block 3075, and the round bar 3072 drives the adjusting screw 3074 to rotate, causing the adjusting screw 3074 to descend along the fixing post 3071, thereby driving the lifting frame 304 and the clamping seat 305 to descend. The lifting frame 304 and the clamping seat 305 drive the detection instrument 4 to descend until the lower end of the clamping seat 305 touches the fixing plate.At this time, the fixing column 3071 is located in the corresponding yield groove on the clamping seat 305, and will not affect the normal descent of the clamping seat 305. When the clamping seat 305 contacts the fixing plate, the detection instrument 4 is located in the shell 1, thus completing the storage of the detection instrument 4. The user then closes the movable cover 2, so that the movable cover 2 and the shell 1 are locked together by the lock. At this time, the shell 1 and the movable cover 2 are closed to form a closed space, thereby storing and protecting the detection instrument 4. When the detection instrument 4 is needed to perform system detection of the payment device, the entire terminal structure is lifted by the handle on the movable cover 2 to move the terminal. When the terminal is moved to a suitable position and placed, the terminal is stably placed by the support feet 7, and the lock is opened. After buckling, flip the movable cover 2 and open it from the shell 1, then turn the adjustment block 3075 in the adjustment frame 307, the adjustment block 3075 rotates with the adjustment screw 3074 and other structures, thereby driving the lifting frame 304 and the clamping seat 305 to rise, the lifting frame 304 and the clamping seat 305 rise with the detection instrument 4 until the detection instrument 4 rises to a certain height. During this process, the clamping seat 305 at one end of the lifting frame 304 moves up through the adjustment screw 3074, and the clamping seat 305 at the other end moves along the guide column 306, thereby ensuring stability during movement. After the detection instrument 4 is raised, the sliding cover plate 604 is moved by the fixed small block 605, and the sliding cover plate 604 moves along the slide groove 603 on the storage box 601. , until the cable in the inner cavity 602 is exposed, take out the cable, connect the end of the cable to the USB interface 11 and the connection port 12, and connect the other end to the payment device to ensure that the payment device is connected to the detection instrument 4, start the detection instrument 4 through the switch, the display screen 8 lights up, and the corresponding indicator light 13 lights up. The maintenance personnel selects the function through the knob 10 and the function key 9, and then starts the payment device to run. The detection instrument 4 detects the system of the payment device and then determines whether the system of the payment device has a fault or anomaly. The detection result is displayed on the display screen 8. The maintenance personnel can correct the system of the payment device according to the detected abnormal point. When the detection instrument 4 is used up, remove the connection The cables are placed in the inner cavity 602 on the storage box 601, and the sliding cover 604 is moved by the fixed small block 605 until the sliding cover 604 is completely closed, and then the positions of the lifting frame 304 and the clamping seat 305 are adjusted by the adjusting frame 307, so that the two structures are lowered with the detection instrument 4 until the detection instrument 4 is stored in the shell 1, and then the movable cover 2 is closed and the lock is locked to store the entire terminal. The structure is simple and the use effect is excellent. During the use and storage of the detection instrument 4, when the detection instrument 4 rises to expose the corresponding connection port, the first flexible strip 502 and the second flexible strip 503 on the fixed frame 501 rise, thereby wiping the inner wall of the shell 1, which can avoid dust on the inner wall of the shell 1.Furthermore, it ensures that the dust at the upper edge of the outer shell 1 is cleaned in advance, preventing dust from falling onto connection ports such as the USB interface 11, thus ensuring the cleanliness of the connection ports. When the detection instrument 4 descends, the two flexible strips wipe the inner wall of the outer shell 1 once, ensuring the cleanliness of the detection instrument 4 after being stored, and also achieving a dust-proof effect. The structure is simple and the operation is convenient. At the same time, the flexible strips in the protection structure 5 can play a buffering role. In this way, when carrying the terminal and moving it, if the terminal accidentally falls to the ground, and if the fastening bolt 308 fixing the detection instrument 4 becomes loose, the detection instrument 4 is no longer fixed between the clamping seats 305 but can move relative to the clamping seats 305. At this time, when the detection instrument 4 moves back and forth, the protection structures 5 at the front and rear ends of the detection instrument 4 can play a buffering and protective role, preventing the connection ports on the detection instrument 4 from directly colliding with the inner wall of the outer shell 1, thereby ensuring the integrity of these connection ports, protecting the integrity of the detection instrument 4 to a certain extent, reducing the use cost, with a simple structure and excellent use effect.
