The inside of the two moving grooves 705 is slidably provided with connecting blocks, which are fixedly connected with the front and rear sides of the cutting saw 703, respectively. The moving grooves 705 and the connecting blocks can limit the cutting saw 703 and also limit the direction of the cutting saw 703, so that the electric cylinder 702 can drive the cutting saw 703 to move in the direction of the moving groove 705 when working, and then drive the cutting saw 703 to move obliquely downward or upward.

[0044] It should be noted that the cutting mechanism 7 is provided with clamping blocks 604 on the left and right sides, so that when the four clamping blocks 604 clamp the rotating shaft, the left and right sides of the cutting point can be clamped and fixed.

[0046] The inner side of the pressing rod 401 is provided with a clamping groove 404 matched with the clamping block 805, the clamping groove 404 is arranged so that, after the pressing rod 401 moves horizontally to the right, the clamping block 805 can be clamped in the clamping groove 404, thereby fixing the pressing rod 401, avoiding that the pressing rod 401 is pushed to reset by the reset spring 402, and the side wall of the mounting frame 701 is provided with a movable slot 10, the front end of the front end lever 802 penetrates through the movable slot 10 and extends above the front end pressing rod 401, and the movable slot 10 provides a moving space for the front end lever 802, so that the lever 802 can smoothly rotate;

[0047] It should be noted that, when the electric cylinder 702 drives the cutting saw 703 to move obliquely downward, the cutting saw 703 can cut the shaft, after the cutting saw 703 cuts off the shaft, the electric cylinder 702 will continue to drive the cutting saw 703 to move obliquely downward by a small distance, at this time, the lower pressing plate 801 below the cutting saw 703 will be in contact with the upper surface of the end of the two levers 802 provided with the jacking spring 803, and will press this end downward, so that the other end of the lever 802 moves upward, drives the clamping block 805 to move out of the clamping groove 404, so that the pressing rod 401 loses the limiting and fixing effect, and then the elastic force of the reset spring 402 and the reset spring 605 is released, the pressing rod 401 and the clamping block 604 are pushed to reset, so that the shaft loses the clamping and fixing effect, facilitating the transfer and discharging of the shaft, and then facilitating the continuous cutting work of the shaft.

[0049] Then the electric cylinder 702 is started, the electric cylinder 702 drives the cutting saw 703 to move to the rotating shaft direction, so that the cutting saw 703 cuts the rotating shaft, after the cutting saw 703 cuts the rotating shaft, the electric cylinder 702 drives the cutting saw to continue to move obliquely downward by a small distance, so that the lower pressing plate 801 presses the one end of the lever 802, and then the lever 802 drives the other end to move upward, the clamping block 805 is removed from the inside of the clamping groove 404, the fixing effect of the clamping block 805 on the pressing rod 401 is lost, then the elastic force of the reset spring one 402 and the reset spring two 605 is released, the reset spring one 402 drives the pressing rod 401 to move left to recover to the initial position, and the reset spring two 605 drives the limiting moving plate 602 to move away from the rotating shaft, so that the clamping block 604 loses the clamping effect on the rotating shaft, facilitating the quick replacement of the rotating shaft and the next cutting work.
