A filling groove 4 is provided on one side of the oil storage tank 3, and a nut is provided on the inner wall of the filling groove 4, and a sealing bolt 5 is connected to the inner thread of the nut.

[0026] In a specific implementation manner, a lubrication device 7 is provided, and when the tool handle body 1 is not in use, the elastic force of the first spring 709 causes the second sealing block 707 to separate from the blocking ring 708, thereby causing the connecting groove 8 to be connected to the oil outlet groove 705, so that the lubricating oil in the oil storage tank 3 flows into the oil outlet groove 705, and the first sealing block 701 is squeezed by the sealing ring 702 through the connecting rod 703, thereby sealing, thereby avoiding the lubricating liquid 6 from flowing out and causing waste when not in use, and then the tool handle body 1 is rotated to drive the first sealing block 701 to move inward by centrifugal force, thereby causing the connecting rod 703 to drive the second sealing block 707 to contact the blocking ring 708, thereby blocking the oil outlet groove 705, and then the lubricating liquid 6 in the oil outlet groove 705 flows out, thereby lubricating the inner cavity 2, thereby reducing the friction of the cutting tool on the inner cavity 2.

[0027] Two long sliding rods 11 are connected to one side of the inner cavity 2, and the outer wall of the long sliding rod 11 is slidably connected to a sliding sleeve seat 13, and the same push rod 9 is connected between the two sliding sleeve seats 13, one end of the push rod 9 is connected to a second spring 10, and the other end of the second spring 10 is connected to one side of the inner cavity 2, and one end of the two long sliding rods 11 is connected to a limiting plate 12.

[0028] In a specific implementation, a push rod 9 is provided so that when the cutting knife is installed, the cutting knife squeezes the push rod 9, and slides on the outer wall of the long sliding rod 11 through the sliding sleeve seat 13, so that the push rod 9 is more stable when moving and avoids deviation. Then, the push rod 9 squeezes the second spring 10, so that the second spring 10 generates a rebound force. When a new cutting knife is replaced, the rebound force of the second spring 10 drives the push rod 9 to reset, so that the push rod 9 pushes out the cutting knife, thereby facilitating the removal of the cutting knife.

[0029] Working principle: When in use, the cutting knife is inserted so that one end of the cutting knife squeezes the push rod 9, and the push rod 9 squeezes the second spring 10, so that the second spring 10 generates a rebound force, and then the handle body 1 is rotated to drive the first sealing block 701 to move inward by centrifugal force, and then the second sealing block 707 is driven by the connecting rod 703 to contact the barrier ring 708, thereby sealing the oil outlet groove 705, so that the lubricating liquid 6 in the oil outlet groove 705 flows out, lubricating the inner cavity 2, thereby reducing the friction force when the cutting knife is installed, and improving the service life of the handle body 1. When replacing the cutting knife, the rebound force of the second spring 10 resets the push rod 9 and squeezes out the cutting knife, making replacement more convenient.
