The placement plate 305 is fixedly connected to one side of the slider 304.

[0025] Further as shown in Figure 1 , Figure 2 and Figure 3 shown, specifically, the punching structure 4 is composed of a cross bar 401, a cross block 402, a second spring 403, a push plate 404, a positioning block 405 and a punching plate 406. A cross groove is formed in the middle of the placement plate 305. The cross bar 401 is fixedly connected inside the cross groove of the placement plate 305. The cross blocks 402 are symmetrically slidably connected to both sides of the outside of the cross bar 401. The second spring 403 is fixedly connected between the two cross blocks 402, and the second spring 403 is sleeved on the outside of the cross bar 401.

[0026] Further as shown in Figure 1 , Figure 2 and Figure 3 shown, specifically, the positioning block 405 is fixedly connected to the top surface of the cross block 402, and the shape of the positioning block 405 is "「". An inclined surface is provided on the top surface of the short side of the positioning block 405;

[0027] Through the provided inclined surface, when the punching plate 406 is installed above the placement plate 305, the positioning groove 407 first squeezes the inclined surfaces of the two positioning blocks 405 on both sides, causing the cross blocks 402 to slide towards each other. Until the punching plate 406 is installed above the placement plate 305, under the elastic action of the second spring 403, the cross blocks 402 are driven to reset, so that the positioning block 405 is stuck into the inside of the positioning groove 407 to fix the installation of the punching plate 406.

[0028] Further as shown in Figure 1 , Figure 2 and Figure 3 shown, specifically, the punching plate 406 is arranged above the placement plate 305. Positioning grooves 407 are symmetrically formed at the left and right ends of the punching plate 406, and the shape of the positioning groove 407 is adapted to the positioning block 405. The push plate 404 is fixedly connected to the bottom surface of the cross block 402;

[0029] By providing the push plate 404, it is convenient for the user to push the two push plates 404, drive the positioning block 405 to move, and disengage from the inside of the positioning groove 407, so as to release the connection between the placement plate 305 and the punching plate 406, and facilitate the replacement of the punching plate 406.

[0030] According to the above working process, it can be seen that: by setting the punching structure 4, the punching plate 406 can be replaced, which is convenient for meeting the requirements of different punching positions, hole sizes and shapes, and improving the applicable range of the device.

[0031] Further, as shown in Figure 1 , Figure 2 and Figure 4 It is specifically noted that the replacement structure 5 is composed of a motor 501, a connecting shaft 502, a threaded rod 504, a positioning plate 505, a connecting column 506 and a limiting block 508. A support frame is connected above the bottom plate 1. The motor 501 is fixedly connected to the lower part of the support frame. The connecting shaft 502 is connected to the lower part of the motor 501. An installation groove 503 is formed in the bottom surface of the connecting shaft 502. The threaded rods 504 are symmetrically and threadedly connected to the left and right sides of the installation groove 503. The positioning plate 505 is rotatably connected to the opposite surfaces of the threaded rods 504, and the other ends of the threaded rods 504 extend out of the connecting shaft 502.

[0032] Further, as shown in Figure 1 , Figure 2 and Figure 4 It is specifically noted that the connecting column 506 is fixedly connected to the top surface of the punching head 6, and the connecting column 506 is adapted to the shape of the installation groove 503. Limiting blocks 508 are symmetrically and fixedly connected to the front and rear side surfaces of the connecting column 506, and sliding grooves adapted to the limiting blocks 508 are formed in the installation groove 503;

[0033] First, align the limiting block 508 with the sliding groove inside the installation groove 503, and install the connecting column 506 inside the installation groove 503 to facilitate the installation of the connecting column 506.

[0034] Further, as shown in Figure 1 , Figure 2 and Figure 4 It is specifically noted that positioning holes 507 are formed in the left and right sides of the connecting column 506, and the positioning plate 505 is adapted to the shape of the positioning holes 507;

[0035] Rotate the threaded rod 504 in the reverse direction to drive the positioning plate 505 to be stuck into the positioning holes 507 to fix the installation of the connecting column 506 and ensure the stability of the punching head 6 during punching.

[0036] This solution has the following working process: When in use, place the circuit board above the punching plate 406, then control the motor 501 to drive the punching head 6 to rotate, and then move the punching head 6 downward to punch the circuit board. The waste material obtained from punching falls into the interior of the punching table 2. After punching is completed, open the door body to clean the waste material inside the punching table 2; when it is necessary to change the punching position or the size and shape of the holes, press the two to drive the push plate 404 to move, and at the same time drive the positioning block 405 to move out of the interior of the positioning groove 407, then the connection between the placement plate 305 and the punching plate 406 can be released, facilitating the upward removal of the punching plate 406. Then place a new punching plate 406 above the placement plate 305. Through the provided inclined surface, when the punching plate 406 is installed above the placement plate 305, the positioning groove 407 first squeezes the inclined surfaces of the two positioning blocks 405 on both sides, causing the cross blocks 402 to slide towards each other. Until the punching plate 406 is installed above the placement plate 305, under the elastic action of the second spring 403, drive the cross blocks 402 to reset, so that the positioning blocks 405 are snapped into the interior of the positioning groove 407 to fix the installation of the punching plate 406, thus completing the replacement of the punching plate 406 and improving the applicable range of the device; when the punching head 6 is worn after long-term use, rotate the threaded rod 504 to drive the positioning plate 505 out of the interior of the positioning hole 507, then the fixation of the connecting column 506 can be released, and the punching head 6 can be removed downward. Replace the new punching head 6. First, align the limiting block 508 with the sliding groove inside the installation groove 503, install the connecting column 506 inside the installation groove 503 to facilitate the installation of the connecting column 506, and then rotate the threaded rod 504 in the reverse direction to drive the positioning plate 505 to snap into the interior of the positioning hole 507 to fix the installation of the connecting column 506 and ensure the stability of the punching head 6 during punching.

[0037] In summary: Through the provided punching structure 4, the punching plate 406 can be replaced, facilitating the satisfaction of requirements for different punching positions, hole sizes, and shapes, and improving the applicable range of the device; through the provided replacement structure 5, it is convenient to quickly replace the punching head 6 when the punching head 6 is worn. The structure is simple, the operation is convenient, and the use efficiency and practicality of the punching device are improved.
