[0029] The box 110 is used to form a closed space to ensure the safety of the experiment. The base 120 is used to fix the bearing 130. The bearing 130 is used to fix the rotating seat 140 and ensure the stability of the rotating seat 140 during rotation. The rotating seat 140 is used to install the placement plate 160 and drive the placement plate 160 to rotate.

[0030] The driving member 150 is used to drive the rotating base 140 to rotate, including a motor 151 fixed on the inner bottom wall of the box body 110, a transmission wheel 152 fixed on the shaft of the motor 151, and a transmission belt 153 with one end sleeved on the transmission wheel 152 and the other end sleeved on the rotating base 140. An annular groove 141 is provided on the outer surface of the rotating base 140, one end of the transmission belt 153 is sleeved in the annular groove 141, and the other end is sleeved on the transmission wheel 152. Through this arrangement, when the motor 151 is started, it drives the transmission wheel 152 to rotate, and the rotation of the transmission wheel 152 drives the rotating base 140 to rotate through the transmission belt 153, and then drives the placement tray 160 to rotate, thereby switching the samples on the placement tray 160.

[0031] The top of the placement tray 160 is provided with a plurality of grooves 161 in a circular array, which can be used to place multiple samples at one time, and a label 162 is fixed on one side of each groove 161, which is convenient for subsequent experimental data corresponding to different samples according to the number. In addition, a cross protrusion 163 is fixed to the bottom end of the placement tray 160, and a cross groove 142 is provided at the top of the rotating base 140. The cross protrusion 163 is embedded in the cross groove 142, which facilitates the placement tray 160 to be taken out and placed from the rotating base 140, further increasing the convenience of use.

[0032] The detection mechanism 200 is used to detect samples, and includes multiple sliding rods 210 fixed on the inner wall of the box body 110, a movable seat 220 movably mounted on the sliding rods 210, a telescopic rod 250 fixed on the inner wall of the box body 110 and fixedly connected to the movable seat 220, a supporting seat 230 movably mounted on one side of the movable seat 220, an electrode 240 fixed on the fixed seat, and a dripping device 260 fixed on the inner wall of the box body 110.

[0033] Two sliding rods 210 are set as a group and are symmetrically arranged in the inner cavity of the box body 110. The bottom end is fixed on the bottom wall of the box body 110, and the top end is fixed to the inner top wall of the box body 110, which is used to install the moving seat 220. The moving seat 220 includes a rectangular plate 221, a plurality of ear plates 222 symmetrically fixed on both sides of the rectangular plate 221, and a support rod 223 arranged on one side of the rectangular plate 221 and connected to the opposite ear plates 222. A through hole 2221 is opened on the ear plate 222 on the other side of the rectangular plate 221. The sliding rod 210 moves through the through hole 2221 to ensure the stability of the entire moving seat 220 when moving up and down along the sliding rod 210.

[0034] The supporting seat 230 includes a sleeve 232 movably mounted on the support rod 223, an L-shaped bracket 231 fixed between the relative sleeves 232, and a spring 233 connecting the top of the sleeve 232 and the ear plate 222. The sleeve 232 is movably mounted on the support rod 223, so that the entire L-shaped bracket 231 can be adjusted up and down, that is, the electrode 240 can automatically adjust its position according to the thickness of the sample to ensure that the inclined end of the electrode 240 can be completely close to the sample. The L-shaped bracket 231 is used to install the electrode 240, and the spring 233 gives the sleeve 232 and the L-shaped bracket 231 a downward force to ensure that the end of the electrode 240 is close to the sample surface.

[0035] The telescopic rod 250 is fixed to the inner wall of the box body 110 through a bracket, and its end is fixedly connected to the movable seat 220 for driving the movable seat 220 to move up and down, that is, driving the supporting seat 230 and the electrode 240 to move up and down.

[0036] The liquid dripping device 260 is used to drip liquid between the opposing electrodes 240 to perform a tracking test.

[0037] The working principle and use process of the present invention are as follows: when in use, a plurality of different samples are placed in the groove 161 on the placement plate 160, and the placement plate 160 is placed on the top of the rotating seat 140, so that the cross protrusion 163 at the bottom end of the placement plate 160 is embedded in the cross groove 142 at the top end of the rotating seat 140, and the telescopic rod 250 is retracted, driving the movable seat 220 to move downward, and the downward movement of the movable seat 220 drives the supporting seat 230 to move downward, and the downward movement of the supporting seat 230 drives the electrode 240 to move downward, so that the inclined end of the electrode 240 is closely attached to the sample surface. Since the supporting seat 230 is movably arranged, and the spring 233 gives the sleeve 232 and the L-shaped bracket 231 a downward force Therefore, the motor 151 can automatically adjust its position according to the thickness of different samples and stick to their surface, and then the test can begin. After the sample test is completed, the telescopic rod 250 drives the movable seat 220 to move upward, and the movable seat 220 moves upward with the supporting seat 230, and the supporting seat 230 moves upward and drives the electrode 240 to move upward synchronously. At this time, the motor 151 starts, driving the transmission wheel 152 to rotate, and the transmission wheel 152 rotates and drives the rotating seat 140 to rotate through the transmission belt 153. The rotating seat 140 rotates and drives the placement plate 160 to rotate. The placement plate 160 rotates to switch the sample on its top and rotate another sample to the test position. The above process can be repeated subsequently.
