[0015] A method for detecting heavy metals in high-salt food, comprising the following steps: first, by pressing a second pressing rod, the lock plate is driven to move inward under the action of a cross bar, and a reset spring is compressed at the same time; when in use, the lock plate is moved inward under the rotation of a limit block, and then at this time, the second pressing rod is driven to move up and down, and the limit block slides under the limit of a protective shell to adjust the height, and at the same time, the device is used for protection when it is inside; when the height is adjusted by the second pressing rod, the second pressing rod is released to allow the lock plate to be clamped on the second card plate to play a fixing role; when the lock plate slides to the top of the second card plate, the connection block is ejected from the outside of the protective shell through a positioning seat; when the screw rods are driven to rotate by starting the second motors on both sides, the front and rear positions of the moving blocks are adjusted according to the use needs when in use; when the moving blocks are driven to rotate by the second motor, and the moving blocks are staggered to both sides, the adjusting rods are driven by the moving blocks to push the connecting blocks, and at the same time, the moving blocks are rotated under the limit of the moving blocks and the screw rods, and at this time, the connecting blocks will tilt to the left and right on one side, and the device orientation position of the upper cover can be adjusted according to the use needs during use;

[0016] Then, the upper cover is pulled upward, and the guide rail slide is driven by the upper cover to make the slide bar in the middle of the fixed guide rail slide inside the slide groove, so as to limit and position the upper cover, and the upper cover slides to the top and then tilts backward to quickly open the food, and the food to be tested is placed into the testing chamber through the through hole of the testing chamber, and then the corresponding fusion testing liquid is added, and then the upper cover is reset, and at this time, the first motor is started to drive the first gear to rotate, and when the first gear drives the second gear to rotate, the second gear drives the connecting rod to rotate at the inner ring tooth end of the sleeve at the same time, so that it can move and rotate at the same time, and the first gear drives the mixing rod to rotate to play the role of main stirring, and the connecting rod rotates at the same time during the movement to play the role of auxiliary stirring, so that the food can be dissolved more easily for testing;

[0017] After the detection is completed, the spring pick is driven out of the card slot by pressing the slide rod body.

This is because the first spring uses the thrust of the push rod on the inclined surface in the middle of the first spring and the top of the second spring during the movement of the first spring. When in use, the push rod moves downward to allow the card block to slide out from the inner wall of the second spring, thereby quickly unlocking the upper cover.

During use, the second spring drives the push rod to move downward, so that the first spring drives the first pressing rod to be pushed outward during use, thereby achieving the effect of rapid disassembly during use.

[0020] 2. The present invention starts the first motor to drive the first gear to rotate. When the first gear drives the second gear to rotate, the second gear drives the connecting rod to rotate at the inner ring tooth end of the ring at the same time, so that it can move and rotate at the same time. During use, the food to be tested can be quickly integrated with the test liquid.

[0021] 3. The present invention drives the lock plate to move inward under the action of the cross bar by pressing the second pressing rod, and compresses the reset spring at the same time. When in use, the lock plate moves inward under the rotation of the limit block. During use, it not only has the effect of height adjustment, but also has a protective effect when the equipment is retracted into the interior.

[0022] 4. The present invention drives the screw to rotate through the second motor, and drives the moving block to adjust the front and rear positions of the equipment during use. When the moving block moves alternately to both sides, the moving block drives the adjusting rod to push the connecting block. At this time, the connecting block will tilt to the left and to the right. During use, the orientation of the device can be adjusted according to the needs. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the lock plate 24 is compressed by the lock plate 24 to allow the reset spring 27 to disengage from the second clamping plate 23 during use, so that the limit block 25 can move up and down under the limit of the protective shell 22 by pressing on both sides, so that the height can be adjusted during use. During use, the height of the device can be adjusted according to actual usage conditions, and when the device is retracted into the protective shell 22, the device can be protected. During use, when the second pressing rod 26 presses the lock plate 24 to contract, the limit block 25 can be pulled out from the interior of the protective shell 22, so that the internal structure can be directly taken out during use, and the internal structure can be maintained and replaced during use.

[0045] Please see attached Figure 1 -Attached Fig. 9, a method for detecting heavy metals in high-salt food, comprising the following steps: first, by pressing the second pressing rod 26, the lock plate 24 is driven to move inward under the action of the cross bar, and the reset spring 27 is compressed at the same time. When in use, the lock plate 24 moves inward under the rotation of the limit block 25, and then at this time, it is driven by the second pressing rod 26 to move up and down, and the limit block 25 slides under the limit of the protective shell 22 to adjust the height. At the same time, the device is used for protection when it is inside. When the height is adjusted by the second pressing rod 26, the second pressing rod 26 is released to allow the lock plate 24 to be stuck on the second clamping plate 23 to fix it, and the lock plate 24 slides When it reaches the top of the second clamping plate 23, the connecting block 33 is ejected from the outside of the protective shell 22 through the positioning seat 28. When the second motors 29 on both sides are started to drive the screw rod 30 to rotate, the moving block 31 is driven to adjust the front and rear positions according to the use needs during use. The second motor 29 drives the moving block 31 to rotate, and when the moving block 31 moves alternately to both sides, the moving block 31 drives the adjusting rod 32 to push the connecting block 33. At the same time, the moving block 31 rotates under the limit of the moving block 31 and the screw rod 30. At this time, the connecting block 33 will tilt to the left and to the right on one side. The device orientation position of the upper cover 1 can be adjusted according to the use needs during use;

[0046] Then, the upper cover 1 is pulled upward, and the guide rail slide plate 3 is driven by the upper cover 1 to make the slide bar in the middle of the fixed guide rail 2 slide inside the slide groove, so as to limit and position the upper cover 1. The upper cover 1 slides to the top and then tilts backward to quickly open. The video to be tested is placed into the testing chamber 14 through the through hole of the testing chamber 14, and then the corresponding fusion testing liquid is added. After that, the upper cover 1 is reset. At this time, the first motor 15 is started to drive the first gear 16 to rotate. When the first gear 16 drives the second gear 17 to rotate, the second gear 17 drives the connecting rod 18 to rotate at the inner tooth end of the sleeve ring 19 at the same time, so that it can move and rotate at the same time. The first gear 16 drives the mixing rod 20 to rotate to play the role of main stirring. The connecting rod 18 rotates at the same time during the movement to play the role of auxiliary stirring, so that the food can be dissolved more easily for testing.

[0047] After the detection is completed, the slide rod body 10 is pressed to drive the spring pick 9 to disengage from the card slot. At this time, the first pressing rod 7 is driven to pop out to the right by the first spring 8. This is because the first spring 8 uses the push force of the top rod 11 on the inclined surface in the middle of the first spring 8 and the top of the second spring 13 during the movement. When in use, the top rod 11 moves downward to allow the card block 12 to slide out from the inner wall of the second spring 13, thereby quickly unlocking the upper cover 1. Conversely, when the first pressing rod 7 is pressed, the top rod 11 is driven upward by the inclined surface of the first spring 8 to allow the card block 12 to expand toward the inside of the connecting shell 5, thereby quickly fixing it when in use.

10. A method for detecting heavy metals in high-salt food, applied to a high-salt food heavy metal detection device according to any one of claims 1 to 9, characterized in that: The following steps are involved: First, the second pressing rod (26) is pressed to drive the lock plate (24) to move inward under the action of the cross bar, and the reset spring (27) is compressed at the same time. When in use, the lock plate (24) moves inward under the rotation of the limit block (25), and then the second pressing rod (26) drives it to move up and down, and the limit block (25) slides under the limit of the protective shell (22) to adjust the height. At the same time, the device is used for protection when it is inside. When the height is adjusted by the second pressing rod (26), the second pressing rod (26) is released to allow the lock plate (24) to be clamped on the second clamping plate (23) to play a fixing role. When the lock plate (24) slides to the top of the second clamping plate (23), the lock plate (24) is pressed. The positioning seat (28) ejects the connecting block (33) out of the protective shell (22). When the second motors (29) on both sides are started to drive the screw rod (30) to rotate, the moving block (31) is driven to adjust the front and rear positions according to the use requirements during use. The second motor (29) drives the moving block (31) to rotate, and when the moving block (31) moves alternately to both sides, the moving block (31) drives the adjusting rod (32) to push the connecting block (33). At the same time, the moving block (31) rotates under the limit of the moving block (31) and the screw rod (30). At this time, the connecting block (33) will tilt to the left and to the right on one side. During use, the device orientation position of the upper cover (1) can be adjusted according to the use requirements. Then, the upper cover (1) is pulled upward, and the guide rail slide plate (3) is driven by the upper cover (1) to slide the slide bar in the middle of the fixed guide rail (2) inside the slide groove, so as to limit and position the upper cover (1). The upper cover (1) slides to the top and then tilts backward to quickly open the upper cover. The food to be tested is placed into the testing chamber (14) through the through hole of the testing chamber (14), and then the corresponding fusion testing liquid is added. After that, the upper cover (1) is reset. At this time, the first motor (15) is started to drive the first gear (16) to rotate. When the first gear (16) drives the second gear (17) to rotate, the second gear (17) drives the connecting rod (18) to rotate at the inner ring tooth end of the sleeve ring (19) at the same time, so that it can move and rotate at the same time. The first gear (16) drives the mixing rod (20) to rotate to play the main stirring role. The connecting rod (18) rotates at the same time during the movement to play the auxiliary stirring role, so that the food can be dissolved more easily for testing. After the detection is completed, the slide rod body (10) is pressed to drive the spring pick (9) to disengage from the card slot. At this time, the first pressing rod (7) is driven to pop out to the right side by the first spring (8). This is because the first spring (8) is pushed by the inclined surface of the push rod (11) in the middle of the first spring (8) and the top of the second spring (13). When in use, the push rod (11) moves downward to allow the card block (12) to slide out from the inner wall of the second spring (13), thereby quickly unlocking the upper cover (1). Conversely, when the first pressing rod (7) is pressed, the inclined surface of the first spring (8) drives the push rod (11) to move upward to allow the card block (12) to expand toward the inside of the connecting shell (5), thereby playing a role of quick fixing when in use.
