The periphery of the lower pressing plate 4 is provided with a square frame 5 in a vertical sliding mode, the square frame 5 is formed by splicing and fixing four pieces of transparent glass, and four inner sides of the square frame 5 are respectively attached to the periphery of the lower pressing plate 4. A lifting component for driving the square frame 5 to slide up and down is arranged between the object stage 2 and the lower pressing plate 4. During the experiment, the test block is placed on holding down plate 4, rethread lifting unit drives square frame 5 and rises, square frame 5 goes up and down to shelter from the region between holding down plate 4 and top board 3, thereby the test block is sealed at top board 3, between holding down plate 4 and the square frame 5, rethread organism 1 drives top board 3 and descends, thereby test the test block, after the experiment is crushed, the residue is difficult for splashing to ground owing to sheltering from under square frame 5, and the residue is all restricted on holding down plate 4, thereby made things convenient for the clearance to the residue.

Referring to fig. 2 and 3, a vertical accommodating groove 6 (see fig. 5) is formed in the upper side of the object stage 2, a vertical supporting column 7 is fixed to the lower side of the lower pressing plate 4, and the bottom end of the supporting column 7 is fixed to the bottom of the accommodating groove 6. The sides of the square frame 5, which face away from the lower pressing plate 4, are respectively abutted against the four groove walls of the accommodating groove 6. A guide plate 15 is fixed on one side of the square frame 5, the upper side of the guide plate 15 is obliquely arranged, and the edge of the upper side of the guide plate 15, which is close to the square frame 5, is higher. When the square frame 5 is at the lowest position, the lower side of the guide plate 15 is attached to the upper side of the objective table 2, the highest position of the upper side of the guide plate 15 is flush with the upper side of the lower press plate 4, and simultaneously the top end of the square frame 5 is flush with the upper side of the lower press plate 4. When holding down plate 4 during the clearance, lifting unit will square frame 5 will be minimum, and the residue on the convenient 4 holding down plate of following of this moment is led away from holding down plate 4 on guide plate 15, has made things convenient for the collection and the clearance to the residue.

Referring to fig. 2 and 3, the lifting assembly includes a threaded screw 8, a connecting plate 9 and a driving member, a vertical sliding groove 10 is provided on a groove wall of one side of the accommodating groove 6, and the connecting plate 9 is slidably disposed in the sliding groove 10. Connecting plate 9 one end is fixed in the inside of square frame 5, and the other end stretches into the inside of objective table 2 through sliding tray 10, and threaded screw 8 is vertical and rotate and install in the inside of objective table 2, and threaded screw 8's both ends rotate respectively and install two upper and lower inboards at objective table 2, and threaded screw 8 wears to locate connecting plate 9 perpendicularly and with connecting plate 9 threaded connection. The driving part is used for driving the threaded screw rod 8 to rotate and comprises a worm wheel 11, a worm 12 and a hand wheel 13. The worm wheel 11 is fixedly sleeved at the bottom end of the threaded screw rod 8, the worm wheel 11 is rotatably installed on the inner side of the objective table 2 and meshed with the worm wheel 11, and one end of the worm 12 penetrates out of the objective table 2 and is coaxially fixed with the hand wheel 13. After the test block is placed on holding down plate 4, drive worm 12 through rotating hand wheel 13 and rotate, because worm 12 and worm wheel 11 mesh to worm wheel 11 and screw lead screw 8 are driven and are rotated, because screw lead screw 8 and connecting plate 9 threaded connection, thereby connecting plate 9 is driven and upwards slides, square frame 5 is consequently driven and is slided to sheltering from between top board 3 and the holding down plate 4, reduces the possibility that the residue splashes to ground, convenient clearance.

Referring to fig. 4, brushes 14 are fixed at the edges of the lower side of the lower pressing plate 4 through bolts, and the bristles of the brushes 14 abut against the inner side of the square frame 5. Along with the lifting of the square frame 5, the brush 14 wipes the inner side of the square frame 5, so that the cleanness of the square frame 5 is conveniently maintained, and the state of the test block is conveniently observed.
