Figure 6 , 7 As shown), the synchronous belt 28 can ensure that the motor four 31 can stably drive the screw three 30 to rotate.

[0024] Example 2

[0025] A guide rail sleeve 3 and a brake sleeve 4 are provided above the chassis 1, and a connecting block 32 is provided above the opening and closing door 2. A sliding block 42 capable of moving left and right is provided inside the guide rail sleeve 3. A connecting rod 33 is connected to one side of the sliding block 42. One end of the connecting rod 33 penetrates the outside of the guide rail sleeve 3 and is fixedly connected to the connecting block 32. A spring 1 34 is sleeved on the surface of the connecting rod 33, and the other end of the spring 1 34 is in pressure contact with the sliding block 42. Two movable teeth 43 and two springs 3 46 are provided inside the sliding block 42. The two movable teeth 43 and the two springs 3 46 are symmetrically distributed in the center. The two movable teeth 43 have engaging teeth on the corresponding sides. A rotating gear 45 capable of rotating is provided between the two movable teeth 43, and the rotating gear 45 is connected to the movable teeth 43 through the engaging teeth. A linear slide groove 47 is provided at the inner end of the movable tooth 43, and a fixed slider 48 is sleeved inside the linear slide groove 47. The fixed slider 48 is fixedly connected to the inner wall of the sliding block 42 (such as Fig.10 As shown in the figure), the linear slide groove 47 cooperates with the fixed slider 48 to limit the moving direction of the movable tooth 43.

[0026] In this embodiment, a winding wheel 44 is coaxially connected to the surface of the rotating gear 45, a movable pull wire 36 is counterclockwise wound on the surface of the winding wheel 44, and a fixed pull wire 35 is connected to the other side surface of the sliding block 42; two steering shafts 37 are provided on the inner front side of the brake sleeve 4, and a slidable electromagnet 23 is provided on the inner rear side of the brake sleeve 4, and the other end of the fixed pull wire 35 passes through a steering shaft 37 and is connected to the electromagnet 23. A limit block 38 is provided on the inner front side of the brake sleeve 4, and a power supply contact 39 is provided at the end of the limit block 38; a spring 40 is provided between the limit block 38 and the electromagnet 23, two contact electrodes 19 are provided on the front side of the electromagnet 23, and a permanent magnet 41 is provided on the rear side of the electromagnet 23, and the other end of the movable pull wire 36 passes through another steering shaft 37 and the electromagnet 23 and is connected to the permanent magnet 41. When the power supply contact 39 is activated to supply power to the electromagnet 23 (such as Fig.11 As shown), the electromagnet 23 will repel the permanent magnet 41 to move backwards, and at the same time, the permanent magnet 41 will also drag the winding wheel 44 to rotate counterclockwise through the movable pull wire 36.

[0027] The working principle of the present invention is as follows: after the motor 3 24 is started, it will drive the screw rod 25 to rotate, and the rotation of the screw rod 25 can make the moving platform 11 move left and right (such as Figure 3 , 4 As shown in the figure), after the motor 1 20 is started, it will drive the screw 1 22 to rotate, so that the lifting platform 6 can drive the motor 2 21 to rise and fall, so that the cutting blade 12 moves closer to the material 14.

[0028] After the motor 4 31 is started, the screw rod 3 30 can be driven to rotate by the synchronous belt 28 structure (such as Figure 6 , 7As shown in the figure), as the screw rod 30 rotates, the slide 17 can move forward and backward, thereby driving the material 14 to move forward and backward, thereby adjusting the relative position of the material 14 and the cutting blade 12.

[0029] When the material 14 needs to be cut, the opening and closing door 2 needs to be closed. At this time, the opening and closing door 2 only needs to be pulled closer to each other, so that the connecting block 32 will drive the sliding block 42 to overcome the elastic force of the spring 1 34 and move to one side (such as Figure 8 , 9 As shown), the movement of the sliding block 42 will pull the electromagnet 23 to move forward through the fixed pull wire 35 (as shown Fig.11 as shown).

[0030] When the sliding block 42 is completely moved to the end of one side, the movable tooth 43 inside the sliding block 42 will be stuck in the pin groove on the right side (the pin groove is located on the inner wall of the end of one side of the guide rail sleeve 3), and the contact electrode 19 will also contact the power supply contact 39. When the power supply contact 39 is activated to supply power to the electromagnet 23 (such as Fig.11 As shown in FIG. 2 ), the electromagnet 23 will repel the permanent magnet 41 to move backwards, and at the same time, the permanent magnet 41 will also drag the winding wheel 44 to rotate counterclockwise through the movable pull wire 36 (as shown in FIG. 2 ). Fig.10 As shown), at this time, the coaxial rotating gear 45 will drive the two movable teeth 43 to move closer to each other, and then withdraw from the pin groove. Under the effect of spring 1 34, the opening and closing door 2 is reopened.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
