A clamping block 85 is fixed to the end of the contact rod 84 away from the swivel 82. A volute spring 86 is fixed to the surface of the swivel 82. The end of the volute spring 86 away from the swivel 82 is fixed to the inner wall of the cavity 81. The clamping block 85 penetrates the groove 80, and the clamping block 85 is slidably connected to the inner wall of the groove 80. Four groups of the clamping blocks 85 are arranged, and the four groups of the clamping blocks 85 are all arranged in a circular array with the center of the cavity 81 as the axis center. A pull rod 89 is fixed to the end of one group of the four groups of the clamping blocks 85 away from the center of the cavity 81. The end of the pull rod 89 away from the clamping block 85 penetrates the connecting plate 7, and the pull rod 89 slides with the connecting plate 7 The movable connection, the surface of the stabilizing column 87 contacts the inclined surface of the block 85, and the block 85 drives the contact rod 84 to move synchronously away from the center of the groove 80. At this time, the surface of the contact rod 84 contacts the inner wall of the contact hole 83, the swivel 82 rotates, and the spiral spring 86 is wound. When the surface of the stabilizing column 87 contacts the top of the groove 80, the block 85 is parallel to the position of the limiting groove 88, and the spiral spring 86 is released, driving the swivel 82 to reverse, and the contact rod 84 drives the block 85 to enter the limiting groove 88 through the contact hole 83. The limiting groove 88 contacts the side of the block 85 away from the inclined surface, limiting the stabilizing column 87, stabilizing the stabilizing plate 14 and the cutting knife 10. At this time, bolts can be fixed without accidental contact causing deviation, and there is no need for personnel to hold the stabilizing plate 14 for installation, saving effort and facilitating installation after maintenance.

[0022] The limiting assembly 9 includes a fixed plate 90, which is fixed on the surface of the connecting plate 7. A spring 91 is fixed on the surface of the fixed plate 90. An L-shaped plate 92 is fixed on the end of the spring 91 away from the fixed plate 90. A movable rod 93 is fixed on the surface of the L-shaped plate 92. The end of the movable rod 93 away from the L-shaped plate 92 passes through the fixed plate 90, and the movable rod 93 is slidably connected to the fixed plate 90. When the block 85 limits the stabilizing column 87, the movable rod 93 is released, and the spring 91 drives the L-shaped plate 92 to return to its position. The L-shaped plate 92 contacts the surface of the pull rod 89 to limit the pull rod 89.

[0023] The side of the block 85 away from the connecting plate 7 is set to be inclined. When being interfered, the block 85 moves synchronously away from the center of the groove 80. The interference hole 83 is set to be arc-shaped. When the interference rod 84 moves with the block 85, the interference hole 83 drives the swivel 82 to rotate. A positioning block 13 is fixed on the top of the stabilizing plate 14, and a positioning groove 12 is provided at the bottom of the connecting plate 7 to facilitate positioning and installation. The positioning block 13 and the surface of the connecting plate 7 are both provided with mounting holes to facilitate bolt fixing.

[0024] A motor 6 is fixed on the top of the top plate 3, and the output shaft of the motor 6 passes through the top plate 3. The output shaft of the motor 6 is fixed on the top of the threaded rod 4. A handle 11 is fixed on the surface of the stabilizing plate 14. When the motor 6 is started, it can drive the connecting plate 7 to move, and then perform the cutting work. The movement of the connecting plate 7 is stabilized by the sliding rod 5. By turning on the forward and reverse rotation of the motor 6, the cutting knife 10 is controlled to descend or rise. The handle 11 is convenient for personnel to replace.

[0025] When the maintained cutting knife 10 needs to be installed, the movable rod 93 is pulled outward to drive the L-shaped plate 92 away from the pull rod 89. At this time, the personnel puts the positioning block 13 into the positioning groove 12, and the stabilizing column 87 enters the groove 80. The surface of the stabilizing column 87 will contact the inclined surface of the block 85, and the block 85 drives the interference rod 84 to move synchronously away from the center of the groove 80. At this time, the surface of the interference rod 84 contacts the inner wall of the interference hole 83, thereby causing the swivel 82 to rotate. At this time, the volute spring 86 is wound up, and when the surface of the stabilizing column 87 contacts the top of the groove 80, the block 85 is parallel to the position of the limiting groove 88, the volute spring 86 is released, driving the swivel 82 to reverse, and the interference rod 84 drives the block 85 to enter the limiting groove 88 through the contact hole 83, and the limiting groove 88 contacts the side of the block 85 away from the inclined surface. , thereby limiting the stabilizing column 87 and further stabilizing the stabilizing plate 14 and the cutting knife 10. At this time, the movable rod 93 is released, and the spring 91 drives the L-shaped plate 92 to return to its position. At this time, the L-shaped plate 92 conflicts with the surface of the pull rod 89, which can prevent the stabilizing plate 14 from being separated from the connecting plate 7 by accidentally touching the pull rod 89 when installing the bolts. At this time, personnel can fix the bolts without accidentally touching the pull rod 89 and causing the stabilizing plate 14 to be separated from the connecting plate 7, which is dangerous. At this time, personnel can fix the bolts without the phenomenon of misconception and deviation. There is no need for personnel to hold the stabilizing plate 14 all the time for installation, which saves effort and facilitates the installation after maintenance. At the same time, when the cutting knife 10 needs to be removed, the bolts are removed, the movable rod 93 is pulled, the L-shaped plate 92 is away from the pull rod 89, and the pull rod 89 is pulled, so that the block 85 is driven to move radially synchronously, and the block 85 is separated from the limiting groove 88. The stabilizing plate 14 and the cutting knife 10 are taken out through the handle 11, which is convenient for personnel to perform maintenance.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
