[0026] The adjusting component 7 is arranged above the base 1, and the adjusting component 7 is used to change the state of the connecting component 8 to facilitate the replacement of the cutting tool 5. The adjusting component 7 includes a fixed column 71, a central shaft 72, a square block 73, a return spring 74, an auxiliary gear 75, a trapezoidal block 76, an auxiliary rack 77, a stop block 78 and a connecting rod 79. The fixed column 71 is fixedly installed on the base 1. The central shaft 72 is movably arranged on the connecting seat 4. The square block 73 is rotatably arranged on the central shaft 72. The return spring 74 is arranged between the square block 73 and the connecting seat 4, and both ends of the return spring 74 are fixedly connected to the square block 73 and the connecting seat 4 respectively. The auxiliary gear 75 is fixedly installed on the end of the central shaft 72 passing through the connecting seat 4. The trapezoidal block 76 is rotatably arranged on the auxiliary gear 75, and the trapezoidal block 76 can slide inside the fixed column 71. The auxiliary rack 77 is fixedly installed on the side wall of the inner chute of the fixed column 71. The stop block 78 is fixedly installed on the central shaft 72, and the stop block 78 can slide inside the connecting seat 4. The connecting rod 79 is fixedly installed on the end of the central shaft 72 away from the auxiliary gear 75, and the connecting rod 79 is inserted into the first worm 81. There is a step design in the inner chute of the fixed column 71, and after the trapezoidal block 76 slides over the step, the auxiliary gear 75 meshes with the auxiliary rack 77. A number of grooves are arranged on the stop block 78, and when the stop block 78 contacts the connecting seat 4, there is a certain friction between the groove and the connecting seat 4. The fixed column 71 is arranged on the side of the connecting seat 4, and the fixed column 71 contacts the connecting seat 4, further enhancing the function of the overall device, simplifying the replacement steps of the cutting tool 5, and improving the overall efficiency.

[0027] Working principle: A U-shaped column 2 is fixed on a base 1. A stamping rod 3 is arranged on the U-shaped column 2. A connecting seat 4 is arranged on the stamping rod 3. The connecting seat 4 slides on the U-shaped column 2. The connecting seat 4 is also connected to a cutting tool 5 through a connecting assembly 8. The stamping rod 3 can thus control the up and down movement of the cutting tool 5 to cut the car door panel. Among them, the stamping rod 3 is an existing technical achievement, so the working principle and specific operation steps of the stamping rod 3 will not be elaborated too much.

[0028] The fixed column 71 is fixed on the base 1. The central shaft 72 is movable on the connecting seat 4. The square block 73 is rotatably connected to the central shaft 72. The square block 73 is also connected to the connecting seat 4 by a return spring 74. The auxiliary gear 75 is fixed to the end of the central shaft 72. The trapezoidal block 76 slides inside the fixed column 71 and is rotatably connected to the auxiliary gear 75. The chute inside the fixed column 71 for the trapezoidal block 76 to slide has a stepped design. The auxiliary rack 77 is fixed on the fixed column 71. The stop block 78 is fixed on the central shaft 72. A small groove is formed on the stop block 78 to generate a certain friction when contacting the connecting seat 4. The connecting rod 79 is fixed on the central shaft 72 and is inserted into the first worm 81. The first worm 81 rotates inside the connecting seat 4. The first worm gear 82 is threadedly connected to the first worm 81 and also rotates inside the connecting seat 4. The second worm 83 is fixedly connected to the first worm gear 82. The second worm 83 is in threaded transmission connection with the second worm gear 84 fixed on the threaded cylinder 85. The threaded cylinder 85 also rotates inside the connecting seat 4. The threaded cylinder 85 is internally threadedly connected with a fastening screw 86. The fastening screw 86 is threadedly connected to the cutting tool 5. When the punching rod 3 is started and drives the connecting seat 4 to slide upward, the trapezoidal block 76 is squeezed by the step of the chute inside the fixed column 71, and the trapezoidal block 76 will move towards the connecting seat 4, causing the auxiliary gear 75 to mesh with the auxiliary rack 77. At the same time, the stop block 78 slides into the connecting seat 4. At this time, the stop block 78 is in the cavity area inside the connecting seat 4. The connecting seat 4 continues to rise. Under the action of the auxiliary rack 77, the auxiliary gear 75 drives the central shaft 72 to rotate. Then, under the linkage of the connecting rod 79, the first worm 81 rotates synchronously. Then, under the transmission of the first worm gear 82, the second worm 83 and the second worm gear 84, the threaded cylinder 85 rotates synchronously. The position of the fastening screw 86 changes and gradually screws out of the cutting tool 5 and disengages from the cutting tool 5. At this time, the cutting tool 5 can be removed. Place a new cutting tool 5 under the connecting seat 4, and then start the punching rod 3, causing the connecting seat 4 to slide downward. The auxiliary gear 75 and the central shaft 72 will rotate in the opposite direction. Then, the threaded cylinder 85 also rotates in the opposite direction, screwing the fastening screw 86 into the cutting tool 5, thereby fixing the position of the cutting tool 5. When the trapezoidal block 76 slides down to below the step of the chute inside the fixed column 71, under the action of the return spring 74, the trapezoidal block 76 is pushed, so that the side surface of the trapezoidal block 76 is always in contact with the surface of the chute inside the fixed column 71. Similarly, the stop block 78 contacts the connecting seat 4 again, restricting the rotation of the central shaft 72 to lock the whole device.
