By providing the avoidance slot 101, when the cutting blade 903 is cutting, it is prevented that the bottom of the cutting blade 903 touches the surface of the base 1 and causes damage.

[0021] See also Figure 1-2 In the embodiment of the utility model, the ends of the movable plate 5 are symmetrically fixed with sliders, one side of the U-shaped support plate 2 is symmetrically provided with slide grooves, and the two ends of the movable plate 5 are slidably installed in the slide grooves on one side of the U-shaped support plate 2 through the sliders. By sliding the two ends of the movable plate 5 on the surface of the U-shaped support plate 2, the stability of the lifting of the movable plate 5 is further improved.

[0022] See also Figure 1-3In the embodiment of the utility model: the pressing assembly 7 includes: a fixed block 701, two fixed blocks 701 are provided, and the two fixed blocks 701 are symmetrically fixedly installed at the bottom of the movable plate 5, a screw rod 702 is rotatably installed between the two fixed blocks 701, and one end of the screw rod 702 extends to the outside of the fixed block 701, and a screw cap is fixedly installed at one end of the screw rod 702 to facilitate the rotation of the screw rod 702, and a threaded sleeve 703 is symmetrically threadedly installed on the surface of the screw rod 702, and the top of the threaded sleeve 703 is slidably installed with the bottom of the movable plate 5, and the front and rear ends of the threaded sleeve 703 are A movable rod 704 is symmetrically and movablely arranged, an upper pressure plate 705 is fixedly installed between the bottoms of the two movable rods 704, the top of the movable rod 704 extends to the upper end of the movable plate 5 through the adjacent through groove 501, a return spring 706 is sleeved on the middle part of the movable rod 704, and one end of the return spring 706 is fixedly connected to the bottom of the threaded sleeve 703, and the other end of the return spring 706 is fixedly connected to the top of the upper pressure plate 705, a limiting ring 7041 is fixedly installed on the surface of the upper end of the movable rod 704, and the bottom of the limiting ring 7041 is placed on the surface of the top of the threaded sleeve 703. When the length of the fireproof sleeve to be cut is shorter, the screw rod 702 is rotated, and the two threaded sleeves 703 symmetrically installed on the surface of the screw rod 702 move relative to each other to adjust the distance between the two upper pressure plates 705. After the position adjustment is completed, the electric hydraulic cylinder 4 is started, so that the output end of the electric hydraulic cylinder 4 pushes the movable plate 5 downward. When the movable plate 5 moves downward, the upper pressure plate 705 first automatically presses and positions the fireproof sleeve placed between the tops of the two placement plates 8. During the continuous descent of the movable plate 5, the two symmetrical movable rods 704 on the top of the upper pressure plate 705 avoid through the through grooves 501 at both ends of the movable plate 5, so that the descent of the movable plate 5 is not interfered with, and then the cutting blade 903 cuts the fixed fireproof sleeve.

[0023] See also Figure 2 In the embodiment of the utility model, both left and right ends of the screw rod 702 are provided with threads, and the threads of the left and right ends are arranged in opposite directions. By arranging the threads of the left and right ends of the screw rod 702 in opposite directions, when the screw rod 702 is rotated, the symmetrical thread sleeves 703 on the surface of the screw rod 702 drive the corresponding upper pressing plates 705 to move relative to or oppositely at the same time, thereby adjusting the distance between the two upper pressing plates 705. When cutting a shorter fireproof casing, it is convenient to adjust the distance between the two upper pressing plates 705, thereby improving the application range of the device.

[0024] See also Figure 1In the embodiment of the utility model, arc grooves are provided on the top of the placement plate 8 and the bottom of the upper pressing plate 705. When the upper pressing plate 705 is lowered to press and fix the fireproof sleeve, the arc grooves on the top of the placement plate 8 and the bottom of the upper pressing plate 705 increase the contact area between the placement plate 8, the upper pressing plate 705 and the fireproof sleeve during pressing, thereby improving the stability during pressing.

[0025] See also Figure 1-2 In the embodiment of the utility model, the cutting assembly 9 includes a positioning plate 901, which is fixedly mounted on one side of the bottom of the mounting block 6, a driving motor 902 is fixedly mounted on the lower end of the positioning plate 901, and a cutting blade 903 is fixedly mounted on the output end of the driving motor 902, and the cutting blade 903 is located directly above the avoidance groove 101. When the output end of the electric hydraulic cylinder 4 pushes the movable plate 5 downward, the driving motor 902 is started, so that the output end of the driving motor 902 drives the cutting blade 903 to rotate, and after the upper pressing plate 705 presses and fixes the fireproof sleeve, the cutting blade 903 cuts the fireproof sleeve through the continued downward movement of the movable plate 5.

[0026] Working principle: When the power is turned on, when the fireproof sleeve is cut, if the length of the fireproof sleeve to be cut is short, the screw rod 702 is rotated, and the two threaded sleeves 703 symmetrically threaded on the surface of the screw rod 702 move relative to each other, so as to adjust the distance between the two upper pressing plates 705. After the position adjustment is completed, the electric hydraulic cylinder 4 and the drive motor 902 are started, so that the output end of the electric hydraulic cylinder 4 pushes the movable plate 5 downward. When the movable plate 5 moves downward, the upper pressing plate 705 first automatically presses and positions the fireproof sleeve placed between the tops of the two placing plates 8. When the movable plate 5 continues to descend, the two symmetrical movable rods 704 on the top of the upper pressing plate 705 avoid the through slots 501 at both ends of the movable plate 5, so that the descent of the movable plate 5 is not interfered. Then, the output end of the drive motor 902 drives the cutting blade 903 to rotate, so that the cutting blade 903 cuts the fixed fireproof sleeve.
