[0051] A rotating shaft 614 is rotatably connected to the upper part of the front side of the mounting plate 65, and the rotating shaft 614 is fixedly connected to the gear 615. The end of the rotating shaft 614 away from the gear 615 is fixedly connected to a winding sleeve 616, and a pull rope 617 is wound around the outside of the winding sleeve 616. The pull rope 617 passes through the mounting plate 65 and is fixedly connected to the bottom of the movable plate 64.

[0052] The two ends of spring 1 67 are fixedly connected to the top of the mounting plate 65 and the bottom of the movable plate 64 respectively.

[0053] A top groove 11 is further formed on the top of the support platform 1 , and a limit block 12 is fixedly connected to the bottom of the movable seat 10 . The limit block 12 is located inside the top groove 11 and is slidably connected to the top groove 11 .

[0054] Example 1: Figures 5-10 As shown, the operator places the sample body 9 to be tested inside the placement box 71, and keeps the top surfaces of all sample bodies 9 pressed against the clamping plate 75 to fix them, connects the colorimeter body 8 to the mobile phone Bluetooth to facilitate viewing of the test data, and then starts the linear guide 4. The linear guide 4 drives the moving seat 10 and the connecting plate 5 to move, and the moving seat 10 drives the limit block 12 to slide inside the top groove 11. The connecting plate 5 drives the multiple placement boxes 71 on the top to move, and the placement box 71 drives the connecting sleeve 72 and the arc-shaped protrusion 74 to move. When the arc-shaped protrusion 74 contacts the left side of the rack 613, since the elastic coefficient of spring three 73 is greater than the elastic coefficient of spring one 67 and spring two 611, under the same force, spring one 67 and spring two 611 are compressed first.

[0055] At this time, the arc-shaped protrusion 74 pushes the rack 613 and the sliding block 610 to move. The sliding block 610 slides on the cross bar 69 and compresses the spring 2 611. The rack 613 drives the gear 615 to rotate. The gear 615 drives the rotating shaft 614 and the winding sleeve 616 to rotate. The winding sleeve 616 reels the pull rope 617. The pull rope 617 pulls the movable plate 64 and the cross plate 62 down. The movable plate 64 compresses the spring 1 67. The cross plate 62 drives the colorimeter body 8 to descend. When the sliding block 610 moves to the rightmost side groove 612, the rack 613 does not move. The colorimeter body 8 descends to the maximum distance and contacts the top surface of the sample body 9 for detection. The detection data is sent to the mobile phone via Bluetooth for the operator to read.

[0056] Then the arc-shaped protrusion 74 is squeezed by the rack 613, and will slide into the connecting sleeve 72 and compress the spring three 73. The placement box 71 continues to move, so that the sample body 9 that has been tested is removed.

The moving plate 64 drives the horizontal plate 62 and the colorimeter body 8 to move up and reset, which is convenient for the detection of the next sample body 9, thereby improving the continuity of the detection, reducing the operator's hand-held operation, and improving the detection efficiency. It solves the problem of inconvenience in color difference detection of a large number of paint spray samples and low detection efficiency.

[0057] A positioning assembly 7 is provided on the top of the connecting plate 5, and the positioning assembly 7 includes a placement box 71 fixedly installed on the connecting plate 5, and a connecting sleeve 72 is fixedly installed on the side of the placement box 71 close to the supporting back plate 2, and a spring three 73 is fixedly connected to the inside of the connecting sleeve 72, and an arc-shaped protrusion 74 is fixedly connected to one side of the spring three 73.

[0060] An auxiliary groove 78 is formed on one side of the placement box 71 close to the screw rod 76 , and a placement plate 79 is fixedly connected to one side of the fixing piece 77 close to the connecting sleeve 72 . The placement plate 79 is slidably connected to the placement box 71 .

[0061] Example 2: Figure 3-Figure 4 and Figure 11-13 As shown, when positioning the sample body 9, the operator rotates the clamping plate 75, places the sample body 9 on the top of the placement plate 79, then rotates the clamping plate 75, and then rotates the screw rod 76. The auxiliary groove 78 limits the fixing plate 77, so that the rotation of the screw rod 76 will drive the fixing plate 77 to move upward, and the fixing plate 77 slides in the auxiliary groove 78 and drives the placement plate 79 to move upward. The placement plate 79 drives the sample body 9 to rise until the top surface of the sample body 9 is pressed against the clamping plate 75, thereby completing the positioning of the sample body 9 and keeping the top surface height of the sample body 9 the same, which is convenient for the subsequent descending detection of the colorimeter body 8 and improves the stability of the detection.

[0062] Working principle: When using this device, first, Figures 1-13As shown, the operator places the sample body 9 on the top of the placement plate 79, and then rotates the pressing plate 75. The placement plate 79 drives the sample body 9 to rise until the top surface of the sample body 9 is pressed against the pressing plate 75. The positioning of the sample body 9 is completed. Then the linear guide 4 is started to work. The linear guide 4 drives the moving seat 10 and the connecting plate 5 to move. The connecting plate 5 drives the multiple placement boxes 71 on the top to move. The arc-shaped protrusion 74 pushes the rack 613 and the sliding block 610 to move. The cross plate 62 drives the colorimeter body 8 to descend. When the sliding block 610 moves to the rightmost side groove 612, the rack 613 does not move, and the colorimeter body 8 descends to The maximum distance is reached, and the top surface of the sample body 9 is contacted for detection. Then the arc-shaped protrusion 74 is squeezed by the rack 613, and it will slide into the connecting sleeve 72 and compress the spring three 73. The placement box 71 continues to move, so that the sample body 9 that has been tested is removed. When the arc-shaped protrusion 74 is squeezed to the side position of the rack 613 away from the mounting plate 65, the spring two 611 drives the sliding block 610 and the rack 613 to reset, the gear 615 rotates, the pull rope 617 pays off, and the spring one 67 drives the moving plate 64 to reset. The moving plate 64 drives the horizontal plate 62 and the colorimeter body 8 to move up and reset, so as to facilitate the detection of the next sample body 9.
