The first embodiment is as follows: as shown in fig. 1-5, the present embodiment describes a hard tissue slice knife rest, comprising a base 1, two vertical rods 2, a propping device 3, a knife supporting block 4 and a bolt 5; the upper end of the base 1 is fixedly connected with two vertical rods 2, and the base 1 is provided with two slots 11; the propping device 3 is arranged at the upper end of the base 1; the bolt 5 passes through the propping device 3 and is inserted into the corresponding slot 11; the knife supporting block 4 is positioned between the vertical rod 2 and the propping device 3.

Each of said vertical bars 3 comprises a bar body 31; the rod body 31 is provided with a chute I32 and a chute II 33 which penetrates through the rod body 31 and is communicated with the chute I32.

The cutter supporting block 4 comprises a sliding block 41 and two sliding rods 43; the sliding block 41 is in sliding fit with the sliding groove I32, two ends of the sliding block 41 are fixedly connected with sliding rods 43, and the sliding rods 43 are in sliding fit with the corresponding sliding grooves II 33; the side of the slide 41 facing the abutment device 3 is also provided with a knife holder 42.

The propping device 3 comprises a triangular block 21, a connecting plate 22, a spring 25, a sliding plate 26, a push plate 29, a screw 210, an inclined plate 212 and a pulling plate 213; one right-angle side of the cross section of the triangular block 21 is arranged at the upper end of the base 1, the other right-angle side of the triangular block 21 is arranged towards the vertical rod 2, the bottom end of the inclined plane of the triangular block 21 is fixedly connected with a connecting plate 22 which is horizontally arranged, and the connecting plate 22 is provided with a through hole 23 for inserting a bolt 5; the bottom end of one side, facing the vertical rod 2, of the triangular block 21 is fixedly connected with a rear baffle 214, and a slideway 24 is arranged between the rear baffle 214 and the triangular block 21; the sliding plate 26 is in sliding fit with the slideway 24, and a spring 25 is fixedly connected between the sliding plate 26 and the bottom surface of the slideway 24; a groove 211 is formed in the middle of one side, facing the vertical rod 2, of the triangular block 21, and a threaded hole which is matched with the groove 211 is formed in one side, close to the inclined plane of the triangular block 21, of the groove 211; the screw 210 is in threaded connection with the threaded hole, and one end of the screw 210 positioned in the groove 211 is fixedly connected with the push plate 29; the upper end of one side of the triangular block 21 facing the vertical rod 2 is also provided with a U-shaped groove 27 matched with the sliding block 41; a clamping groove is formed in the inclined surface of the triangular block 21; the inclined plate 212 is provided with a through hole in sliding fit with the screw 210, and the inclined plate 212 is sleeved on the screw 210 and in sliding fit with the clamping groove; the bottom end of the sloping plate 212 is also fixedly connected with a pulling plate 213. The screw 210 prevents the wax sheet from continuously sliding down the inclined surface of the triangular block 21.

The sliding plate 26 is blocked at the side surface of the groove 211 when the sliding plate 26 is only acted by the elastic force of the spring 25.

When the through holes 23 on the connecting plate 22 are communicated with the slots 11 far from the vertical rods 3, the sliding blocks 41 are separated from the U-shaped grooves 27, and the sliding blocks 41 are positioned at the upper ends of the sliding plates 26.

When the through holes 23 on the connecting plate 22 are communicated with the slots 11 far away from the vertical rods 3, the distance between the vertical surfaces of the triangular blocks 21 and the vertical rods 3 is equal to the width of the cutter supporting groove 42 and smaller than the height of the cutter 6, so that the cutter 6 is prevented from toppling over;

when the through holes 23 on the connecting plate 22 are communicated with the slots 11 close to the vertical rods 3, the distance between the vertical surfaces of the triangular blocks 21 and the vertical rods 3 is the same as the thickness of the cutter 6, so that the cutter 6 is fixed, and shaking during slicing is avoided.

The working principle of the utility model is as follows: when the device is used, the bolt 5 is pulled out, then the triangular block 21 is pushed in the direction away from the vertical rod 3, the through hole 23 on the connecting plate 22 is communicated with the slot 11 far from the vertical rod 3, the bolt 5 is inserted into the slot 11 through the through hole 23, then the last blade 6 is taken out by a tool such as tweezers, and then two slide bars 43 are pushed downwards, the slide bars 43 drive the slide blocks 41 to move downwards, the slide blocks 41 are positioned at the upper ends of the slide plates 26, so that the slide blocks 41 drive the slide plates 26 to move downwards in the downward moving process, the springs 25 are compressed, when the slide blocks 41 move downwards to the lowest end, the lower ends of the knife supporting grooves 42 and the lower end faces of the grooves 211 are positioned on the same horizontal plane, the received gravity of the slide blocks 41 is larger than the elastic force of the springs 25 at the moment, an operator rotates the screw rods 210 to drive the push plates 29 to move, pushing the cutter 6 positioned at the outermost side inside the groove 211 into the cutter supporting groove 42, lifting the slider 41 upwards, moving the sliding plate 26 upwards along with the slider 41 under the action of the elastic force of the spring 25, shielding the groove 211, lifting the slider 41 to the highest point of the sliding groove I32, supporting the slider 41 by one hand, pulling out the plug pin 5 by the other hand, pushing the triangular block 21 towards the slider 41, positioning a part of the slider 41 in the U-shaped groove 27, clamping the cutter 6 through the inner wall of the cutter supporting groove 42 and the vertical surface of the triangular block 21, inserting the plug pin 5 into the slot 11 close to the vertical rod 3 through the perforation 23, namely completing replacement, wherein an operator does not need to contact the cutter 6 in the process of installing the cutter 6, and the installation position of the cutter 6 can be limited through the cutter supporting groove 42 without subsequent calibration, so that the cutter is prevented from being cut;

after slicing operation, the wax sheet can drop onto the inclined plane of the triangular block 21, and the length of the inclined plate 212 at the upper end of the screw rod 210 is 0.5-1cm, which is smaller than the length of the wax sheet, so that when the wax sheet is attached to the inclined plane of the triangular block 21 once in the downward sliding process along with the increase of the cutting quantity of the wax sheet, the part of the wax sheet on the inclined plate 212 can be separated from the inclined plane of the triangular block 21 only by pulling the pulling plate 213, thereby being convenient for operators to take down the wax sheet by using auxiliary devices such as writing brushes, hairbrushes and the like.
