[0003] Existing technologies, such as the utility model patent with publication number CN220887571U, disclose a leather punching device for processing and producing trolley bags. This patent uses a positioning plate and a pusher. The pusher is fixed on both sides of the rotating plate body, and the positioning plate is located above the pusher. A positioning block is fixedly set in the middle part of the positioning plate. By operating the two clamping components and moving the pull rod, the elastic clamping plate folds over. The pusher is activated, causing the positioning plate to move. Then, the pull rod is released, and the elastic clamping plate resets. After resetting, the elastic clamping plate presses down on the leather body. The multiple elastic clamping plates provide a limiting effect on the leather body on the rotating plate body, making the leather body more firmly placed on the rotating plate body, improving the stability of the leather body on the rotating plate body, and thus improving the punching quality of the leather body.

The inner wall of the movable plate 308 is provided with a connecting groove 318, two positioning grooves 309 and several positioning holes 312. The inner wall of the positioning groove 309 is slidably connected with a connecting block 311. The upper surface of the two connecting blocks 311 is fixedly connected with an adjusting plate 313. The inner wall of the adjusting plate 313 is provided with a connecting groove 318. The connecting groove 318 is slidably connected with the punch 5. The side of the adjusting plate 313 near the positioning hole 312 is fixedly connected with a positioning block 314. The inner wall of the positioning block 314 is slidably connected with an insertion rod 315. The insertion rod 315 is slidably connected with the positioning hole 312. When personnel need to punch holes in the irregularly shaped leather body 2, it allows for convenient punching and adjustment of the hole spacing, thereby improving the efficiency and accuracy of punching.

[0034] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary structure 4 includes a connecting plate 401, which is fixedly connected to an adjusting plate 313. Two telescopic rods 402 are fixedly connected to the upper surface of the connecting plate 401. An installation plate 404 is fixedly connected to the end of the two telescopic rods 402 away from the connecting plate 401. A compression spring 403 is sleeved on the arc surface of the telescopic rod 402. The two ends of the compression spring 403 are fixedly connected to the connecting plate 401 and the installation plate 404 respectively.

A pressing plate 410 is fixedly connected to the side of the auxiliary block 406 away from the installation plate 404. When personnel need to continuously punch holes using the puncher 5, the puncher 5 can be limited by two extrusion plates 410 and two springs 317, thus facilitating continuous punching of the irregularly shaped leather body 2 and improving punching efficiency. Protective pads 411 are fixedly connected to the sides of the two extrusion plates 410 that are close to each other, and the two protective pads 411 abut against the puncher 5. The protective pads 411 protect the puncher 5 and prevent direct contact between the puncher 5 and the extrusion plates 410. Several anti-slip grooves 409 are evenly distributed on the arc surface of the auxiliary plate 408. The anti-slip grooves 409 increase the friction between the personnel's hands and the auxiliary plate 408, preventing slippage during rotation of the auxiliary plate 408.

[0035] The working principle of the irregular leather perforation spacing adjustment and positioning device provided by this utility model is as follows: When a person needs to punch holes in the irregular leather body 2, the person can first move the irregular leather body 2 to the fixed plate 301. Then, the person uses the auxiliary rod 307 to drive the turntable 306 to rotate. The turntable 306 drives the lead screw 304 to rotate. The lead screw 304 drives the moving block 305 to move downward. The moving block 305 drives the moving plate 308 to move downward. The moving plate 308 drives the two connecting blocks 311 and the two limiting rods 310 to move downward. The two connecting blocks 311 drive the adjusting plate. 313 moves downwards, the adjusting plate 313 drives the positioning block 314 to move downwards, the positioning block 314 drives the spring 317 to move downwards, the spring 317 drives the insertion rod 315 to move downwards, and the insertion rod 315 drives the pull ring 316 to move downwards until the moving plate 308 abuts against the irregular leather body 2. After the personnel determine the position to be drilled, the personnel can first use the pull ring 316 to drive the insertion rod 315 to move upwards. The pull ring 316 facilitates the movement of the insertion rod 315, improving the ease of operation. Then, the insertion rod 315 drives the spring 317 to pull upwards. The spring 317 can limit the insertion rod 315, preventing it from sliding out of the inner wall of the positioning hole 312 during the drilling process of the irregular leather body 2. Once the insertion rod 315 slides out of the inner wall of the positioning hole 312, the operator moves the adjusting plate 313, which in turn moves the two connecting blocks 311 and the positioning block 314. The connecting block 311 slides on the arc surface of the limiting rod 310, which limits the connecting block 311 and prevents it from misaligning during sliding on the inner wall of the positioning groove 309. Then, the positioning block 314 moves... The insertion rod 315 and spring 317 move until the connecting groove 318 corresponds to the position where a hole needs to be punched. Then, the operator releases the pull ring 316, at which point the spring 317 rebounds, causing the insertion rod 315 to move closer to the positioning hole 312 until the insertion rod 315 slides into the inner wall of the positioning hole 312. Then, the operator slides the punch 5 into the inner wall of the connecting groove 318, so that the punching end of the punch 5 abuts against the irregular leather body 2. Finally, the punch 5 is struck to achieve the punching effect. When the operator needs to punch again, the distance between the next punching position and the already punched position can be adjusted according to the position of several positioning holes 312.

[0036] Additionally, when the operator slides the punch 5 into the inner wall of the connecting groove 318 to punch holes in the irregularly shaped leather body 2, the operator can first use the rotating column to drive the threaded rod 407 to rotate. The anti-slip groove 409 on the arc surface of the rotating column increases the friction between the operator's hand and the auxiliary plate 408, preventing slippage during the rotation of the auxiliary plate 408. Then, the threaded rod 407 drives the two auxiliary blocks 406 to move closer to each other. The auxiliary blocks 406 drive the extrusion plate 410 to move closer to the punch 5. The extrusion plate 410 drives the protective pads 411 to move closer to the punch 5 until the two protective pads 411 abut against the punch 5. The protective pads 411 can provide pressure on the punch 5. The protection mechanism prevents the punch 5 from directly contacting the extrusion plate 410. When the punch 5 is struck, it causes the two protective pads 411 to move downwards. The protective pads 411 then cause the extrusion plate 410 to move downwards, which in turn causes the auxiliary block 406 to move downwards. The two auxiliary blocks 406 then cause the mounting plate 404 to move downwards, which in turn causes the output ends of the threaded rod 407 and the two telescopic rods 402 to move downwards. The mounting plate 404 also causes the two compression springs 403 to retract. After the punch 5 has punched the irregular leather body 2, the two springs 317 rebound, causing the punch 5 to move back to its initial position, thus facilitating subsequent continuous punching by the punch 5.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
