The protective frame 801 is fixedly installed at the output end of the first electric telescopic rod 7. A second electric telescopic rod 802 is fixedly installed at the top of the interior of the protective frame 801. The second electric telescopic rod 802 is electrically connected to the transmitter 11 and the receiver 12. The output end of the second electric telescopic rod 802 is fixedly connected to a fixed block 803. A mounting groove 804 is penetrated at the right end of the fixed block 803. A second motor 805 is fixedly installed in the mounting groove 804. The output end of the second motor 805 penetrates the front end of the mounting groove 804 and is fixedly installed with a cutting knife 806. When the second electric telescopic rod 802 is retracted, the cutting knife 806 can completely enter the interior of the protective frame 801 to avoid the cutting knife 806 being exposed to the outside, which increases the risk of injury to the operator.

[0026] Reference Figure 1 , Figure 3 and Figure 4 As shown, a fixing assembly 9 is provided at the upper end of the base 1, and the fixing assembly 9 includes a rectangular groove 901, which is opened at the upper end of the base 1, and a bidirectional threaded rod 902 is rotatably installed inside the rectangular groove 901. A third motor 906 is fixedly installed at the right end of the base 1, and the output end of the third motor 906 penetrates into the interior of the rectangular groove 901 and is fixedly connected to the right end of the bidirectional threaded rod 902. The surfaces of both ends of the bidirectional threaded rod 902 are threadedly connected with second moving blocks 903, and the upper ends of the two second moving blocks 903 are fixedly connected with limiting plates 904. The inner sides of the two limiting plates 904 are provided with rubber pads 905, and the rubber pads 905 can prevent the limiting plates 904 from directly contacting the metal plate to prevent damage to both sides of the metal plate. An extension plate 10 is fixedly installed at the front end of the two mounting plates 2. A transmitter 11 is provided at the right end of the left extension plate 10, and a receiver 12 is provided at the left end of the right extension plate 10. A grating is formed between the transmitter 11 and the receiver 12. The parallel light beams of the grating can cover the monitoring area. When there is no object blocking the light beam, the receiver 12 can receive all the light beams emitted by the transmitter 11 and judge that there are no invading objects in the area. When a person's arm enters the grating area, one or more of the light beams will be blocked, resulting in the receiver 12 being unable to receive all the light beams. The receiver 12 will detect this change, and the second electric telescopic rod 802 will not drive the cutting knife 806 to extend outside the protective frame 801 to ensure the safety of personnel.

[0027] The working principle and use process of the utility model are as follows: when in use, the metal plate to be cut is placed on the upper end of the base 1, and the bidirectional threaded rod 902 is driven to rotate by the third motor 906. The rotation of the bidirectional threaded rod 902 drives the two second moving blocks 903 to move toward each other, and then drives the limiting plates 904 at the upper ends of the second moving blocks 903 to move toward each other, until the rubber pads 905 on the inner sides of the two limiting plates 904 abut against the two sides of the metal plate. At this time, the metal plate is fixed. After fixing, the operator's hands need to be at the front end of the two extension plates 10 to send A straight line is formed between the transmitter 11 and the receiver 12, forming a grating. When there is no object blocking the light beam, the receiver 12 can receive the light beams emitted by all the transmitters 11 and judge that there is no object in the area. After judging that there is no object, the second electric telescopic rod 802 will drive the cutting knife 806 to extend out of the protective frame 801, and the cutting knife 806 is driven to move downward by the first electric telescopic rod 7, and the one-way threaded rod 3 is driven to rotate by the first motor 5. The rotation of the one-way threaded rod 3 drives the first moving block 6 to move, thereby cutting the metal plate.
