[0031] The cleaning structure includes a cleaning sleeve 216 provided at the lower end of the fixed sleeve 202. The cleaning sleeve 216 is detachable. A plurality of soft brushes 217 are fixed to the bottom end of the cleaning sleeve 216. The plurality of soft brushes 217 are distributed around the center of the cleaning sleeve 216.

[0032] The rotating structure includes a limiting rod 219 fixed to the inner wall of the fixed sleeve 202 near the lifting disc 203. A spiral groove 220 is formed on the side wall of the rotating sleeve 204. The limiting rod 219 is in sliding fit with the spiral groove 220.

[0033] The limiting structure includes two symmetrical fixed frames 207 fixed to the lower end of the lifting disc 203. A limiting block 206 is slidably installed in the fixed frame 207. A limiting spring is connected between the limiting block 206 and the fixed frame 207. Two symmetrical limiting frames 212 are fixed to the lower part of the side wall of the fixed sleeve 202.

[0035] The clamping assembly includes two symmetrical lead screws 214 rotatably provided at the upper end of the rotating sleeve 204. Two front and rear symmetrical clamping plates 215 are provided between the two lead screws 214. The thread directions of the front and rear ends of the lead screw 214 are opposite. The clamping plate 215 is threadedly connected to the lead screw 214. The clamping plate 215 is slidably connected to the rotating sleeve 204. The clamping plate 215 is arc-shaped. A runner is fixed to the end of the lead screw 214. First, the test tube 205 is clamped and fixed by the clamping assembly, and then the test tube 205 is placed in the detection pot 100 for heating through the placement assembly. After heating, the limiting structure is used to drive the test tube 205 to pop up upward for reset. Furthermore, during the process of the test tube 205 popping up upward, the cleaning structure is used to drive the test tube 205 to rotate. When the test tube 205 rotates and pops up upward, the cleaning structure wipes off the oil adhered to the side wall of the lower end of the test tube 205 in all directions, preventing the oil from adhering to the side wall of the lower end of the test tube 205 and causing inconvenience during the taking and placing and movement of the test tube 205, and preventing the oil from dripping onto the test bench, thereby facilitating the taking and placing of the heated test tube 205 and reducing certain pollution to the environment.

[0036] Working principle: First, place the placement rack 201 on the upper end of the detection pot 100, insert the test tube 205 into the rotating sleeve 204, so that the bottom end of the test tube 205 is close to the wiping plate 218 at the upper end of the cleaning sleeve 216, and then rotate the lead screw 214 to drive the front and rear clamping plates 215 to clamp and fix the middle test tube 205, and then press the pressing rod 209 downward to drive the pressing block 208 to move downward, and drive the lifting plate 203 to move downward, and store the downward pressure spring at the lower end of the lifting plate 203. When the limit stop in the fixed frame 207 at the lower end of the lifting plate 203 is When block 206 moves to the limit frame 212 below the side wall of the fixed sleeve 202, the limit block 206 will break away from the obstruction of the inner wall of the fixed sleeve 202 and be quickly inserted into the limit frame 212, and then the limit frame 212 limits the limit block 206, prompting the lifting plate 203 to stay here, and then the lifting plate 203 drives the lower end of the test tube 205 clamped by the clamping plate 215 to be inserted into the oil inside the detection pot 100, so that the test tube 205 is limited here, and the oil inside the detection pot 100 heats the sample in the test tube 205.

[0037] After heating is completed, the pressing pad is pressed downward to drive the pressing column 211 to move downward, drive the pressing plate 210 to move downward, squeeze the limit block 206, drive the limit block 206 to move toward the test tube 205, and make the limit block 206 break away from the limit block of the limit frame 212. Then, the force storage effect of the downward pressure spring is used to drive the downward pressure spring to drive the lifting plate 203 and the rotating sleeve 204 to pop up quickly, thereby driving the test tube 205 held by the clamping plate 215 to move upward. When the test tube 205 pops up, the limiting rod 219 on the inner wall of the fixed sleeve 202 slides with the spiral groove 220 on the side wall of the rotating sleeve 204, thereby prompting the rotating sleeve 204 to rotate while moving upward, thereby prompting the test tube 205 to rotate while moving upward, so that the multiple soft brushes 217 at the bottom end of the cleaning sleeve 216 are used to clean the lower end side wall of the test tube 205 in all directions to prevent oil from adhering to the side wall of the test tube 205.

[0038] Then, as the test tube 205 moves upward, after the side walls of the test tube 205 are cleaned, the side walls of the test tube 205 are immediately wiped using the wiping cloth at the ends of the multiple wiping plates 218 at the upper end of the cleaning sleeve 216, and the oil on the side walls of the test tube 205 is wiped clean in all directions. Then, the test tube 205 is released from the clamp and the test tube 205 is taken out for the next step of testing to prevent the oil from adhering to the side wall of the lower end of the test tube 205, causing inconvenience when taking and moving the test tube 205, and to prevent the oil from dripping on the test bench, thereby facilitating the taking and placing of the heated test tube 205 and reducing certain pollution to the environment.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
