from the first through hole 24 through hydraulic oil, the second through hole 44 is communicated, so that the hydraulic oil can rapidly flow into a rod cavity from a rodless cavity of the first piston cylinder 21, when the piston plate 22 moves upwards, the elastic rope 45 pulls the rubber plug 41 to reset, then the rubber plug 41 is sealed with the top end of the first through hole 24, and then the hydraulic oil can only flow out of the second through hole 44, therefore, the speed of the piston plate 22 returning upwards is slowed down, the guide rod 43 is used for positioning the fixing plate 42 so as to drive the rubber plug 41 to seal the first through hole 24, the parts are matched with each other, so that the speed of returning the piston plate 22 moving upwards can be reduced, and the speed of returning downwards is not changed, when the device is used, the first rotating shaft 56 is rotated, then the first rotating shaft 56 drives the gear 55 to rotate, so as to drive the rack 53 to move downwards, then the slider 54 pulls the telescopic rod 51 to move downwards, after the sample is taken out, the device can be convenient for a worker to return the sample carrying plate 18, when the sample is pressed, the sample carrying plate 18 drives the telescopic rod 51 to move downwards, then the rack 53 slides in the first sliding groove 52, when the rotating shaft needs to be rotated, the handle 62 is pulled by hand, then the square tube is taken out from the square groove 61, the square rod 64 slides in the handle 62, thus, the fixing of the handle 62 is released, the handle 62 is rotated to drive the first rotating shaft 56 to rotate, when the height of the first rotating shaft 56 is required, the handle 62 is pressed to insert the square cylinder into the square groove 61 to fix the square sleeve 63, so that the handle 62, the first rotating shaft 56 and the gear 55 are fixed, the first rotating shaft 56 can be conveniently rotated by a worker through the arrangement, meanwhile, the first rotating shaft 56 can be fixed, the sample loading plate 18 is prevented from moving upwards when raw materials are placed, when the sample loading plate 18 moves downwards, the sample loading plate 18 pushes the moving rod 74 to move downwards, then the moving rod 74 pushes the inclined rod 73, the fixed disk 72 and the second rotating shaft 71 to rotate anticlockwise, so that the arc-shaped rods 75 are mutually opened, when the sample loading plate 18 returns upwards, the torsion spring drives the second rotating shaft 71 to return, so that the arc-shaped rods 75 are driven to return, then the magnetic ball 79 will be attracted by the magnetic block, then the elastic sheet 78 will bend, then when the worker places the raw material, the sample-carrying plate 18 will push the moving rod 74 to move downwards again, so as to make the arc rod 75 rotate, further make the magnetic block 791 separate from the magnetic ball 79, then the elastic sheet 78 will drive the magnetic ball 79 to strike the side wall of the first cavity 77, so as to make the inside wall of the forming cylinder 15 vibrate, further clean the raw material adhered on the inside wall of the forming cylinder 15 due to extrusion, thereby avoiding affecting the ingredient content of the raw material, and thus improving the accuracy of the experimental analysis, the extrusion block 76 will extrude the connecting rod 82, so as to drive the piston rod 84 to move, thereby extract the gas in the collection box 85, so as to extract the raw material remained on the top side of the forming cylinder 15 through the absorption hopper 89, when the worker places the raw material, a small amount of raw material will be sprinkled on the top of the forming cylinder 15 due to hand shaking, thereby cleaning the top of the forming cylinder 15 and reducing the error, and the third spring is used for driving the piston rod 84 to reset.
