other rolling roller 203, namely, the adhesive tape 208 passes through the bottom end of the circular arc-shaped surface of the pressing block 12, when the pressing block 12 starts to touch the floor, one line on the adhesive tape 208 firstly touches the floor, and the adhesive tape 208 can temporarily adhere and fix the floor at the moment, that is, the condition that the floor at this time cannot slip or shift in position can be ensured, so that the operation convenience can be greatly improved, and when the floor is replaced later, in the process of testing, if the single-sided adhesive tape 208 at the bottom end of the pressing block 12 is not sticky, the knob 207 inserted into the jack 204 can be rotated at this time, the waste adhesive tape 208 can be wound outside the other winding roller 203 in a winding manner, so that the effect of convenient and quick replacement can be achieved, then the screw rod 9 is rotated until the pressing block 12 presses the floor to break, at this time, the tension and compression sensor 11 can transmit compression data to the display on the machine base 1 to display the compression resistance value of the floor to be tested, and when the pressing block 12 descends, the third sliding block 408 in the guide rod 402 can be driven to slide down in the second sliding groove 401, because the other end of the pull rope 406 connected with the third slide block 408 is connected with the second slide block 404, and the other end of the second slide block 404 is connected with the inner side wall of the machine base 1 through the first spring 405, and the first spring 405 is always in a stretched state, namely, when the third slide block 408 slides down, the second slide block 404 is pulled by the first spring 405 to move towards the direction of the placing seat 304 due to the loose force of the pull rope 406, namely, when the pressing block 12 slides down, the two protective covers 403 can be synchronously driven to move towards the direction of the placing seat 304, and when the pressing block 12 just presses against the floor, the protective covers 403 can shield and protect the two ends of the floor placed on the placing seat 304, so that the operation safety can be improved, the operator is prevented from being accidentally injured when the floor breaks, when the pressing block 12 is completely extruded and rises, the two protective covers 403 can be reset again under the pulling force of the pull rope 406, therefore, the floor can not be affected in placement and taking out, the operation is convenient and quick, the synchronism is high, during the use of the device, the pull rod 602 can be moved from the vertical groove of the limit groove 601 to the transverse groove of the limit groove 601, at the moment, the pull rod 602 is not limited, the rubber plug 605 fixed with the second spring 604 can be forced to press the butter in the oil storage cavity 606 under the pulling force of the second spring 604, the butter in the oil storage cavity 606 can be forced to flow out to the outer surface of the screw rod 9 from the position of the oil outlet 608, the automatic lubrication work can be carried out on the screw rod 9, the operation smoothness of the screw rod 9 can be ensured, the service life of the screw rod 9 can be prolonged, when the device is not used, the pull rod 602 is pulled to the leftmost side of the limit groove 601 again, and then the pull rod 602 is pulled forward to the vertical groove of the limit groove 601, at this time, the pull rod 602 can be limited, the butter inside the oil storage cavity 606 can not be pressurized, if the testing interval supporting force needs to be changed, only the worm 301 needs to be rotated outside, the worm 301 rotates to drive the first worm wheel 306 outside the first screw 305 to rotate, thereby enabling the first screw 305 to rotate, since the directions of threads at two ends of the first screw 305 are opposite, the two placing seats 304 can be driven to be away from or close to each other, the testing of different interval supporting forces is applicable, the applicability of the device is increased, and since the second worm wheel 506 is meshed with the worm 301, the second worm wheel 506 can be driven to rotate while the worm 301 drives the first worm wheel 306 to rotate, and therefore the second screw 504 can be driven to rotate, since the second screw 504 is opposite to the threads at two ends, the two limiting blocks 502 can be simultaneously driven to adjust the positions according to the two placing seats 304, at this time, the sliding distance of the protective cover 403 can be limited and controlled, that is to say, when the interval between the two placing seats 304 is increased, the two limiting blocks 403 can be blocked by the two limiting blocks, and the two limiting blocks 403 can be just moved to the two limiting seats 502 at the two end positions of the two limiting blocks, and the two limiting blocks can be just blocked by the two limiting seats 403, so that the two limiting blocks can be just moved to the two more than the two limiting seats 403.
