The bevel gear 210 is rotatably connected inside the annular bracket 29, and it meshes with the upper bevel gear 5. When bevel gear 5 rotates, it drives bevel gear 210 to rotate synchronously, achieving vertical power transmission. A threaded rod 11 is threadedly connected inside bevel gear 210, and the threaded rod 11 engages with bevel gear 210 through a threaded structure. When the bevel gear 10 rotates, it can drive the threaded rod 11 to move up and down in the vertical direction. A pressure plate 12 is fixedly connected to the bottom of the threaded rod 11. The pressure plate 12 adjusts its height as the threaded rod 11 moves up and down. It is used to press and fix the car floor mat in a designated position before processing, so as to prevent the floor mat from shifting during the drilling process. Two guide posts 7 are fixedly connected to the top of the pressure plate 12. The two guide posts 7 are symmetrically distributed on both sides of the top of the pressure plate 12, providing stable guidance for the up and down movement of the pressure plate 12 and preventing the pressure plate 12 from tilting and rotating during the movement.

[0033] Reference Figures 1-3The main frame 1 has a square slot 15 inside, which is located in the middle area of ​​the main frame 1. Its size is adapted to the shape of the mold 17, providing sufficient space for the installation of the mold 17. The four sides of the square slot 15 have grooves 16, which facilitates the operator to pick up, put down and adjust the position of the mold 17. The mold 17 is slidably connected to the inner wall of the square slot 15, which facilitates the quick replacement of the corresponding mold 17 according to the processing needs of different models and sizes of car floor mats. The center of the mold 17 has a round hole 18, which is precisely aligned with the movement trajectory of the subsequent cutting tool 14 to ensure accurate drilling position. The outer wall of the mold 17 has four pull grooves 19, which are evenly distributed on the four sides of the outer wall of the mold 17. The operator can easily pull the mold 17 to adjust or replace its position by inserting fingers or tools into the pull grooves 19, which improves the convenience of operation.

[0034] Reference Figure 1 , Figure 4 and Figure 5 A collection bracket 20 is fixedly connected to the bottom wall of the main frame 1. The collection bracket 20 is installed directly below the square groove 15 on the bottom wall of the main frame 1. A collection box 21 is slidably connected inside the collection bracket 20. The collection box 21 can slide back and forth along the internal track of the collection bracket 20. When the amount of drilling waste collected in the collection box 21 reaches a certain amount, the operator can pull it out for cleaning. After cleaning, it can be pushed back into place. The operation is convenient. A lock shell 22 is fixedly connected to the outside of the collection box 21. The inside has a hollow cavity to provide installation space for the abutment plate 23, the latch 24, and the spring 25. The abutment plate 23 is slidably connected inside the lock shell 22. The abutment plate 23 can slide up and down along the inner wall of the lock shell 22. The latch 24 is fixedly connected inside the abutment plate 23. When the abutment plate 23 slides, the latch 25... 4. Move accordingly to achieve insertion or separation with the locking groove 27. The locking tongue 24 is fitted with a spring 25. When the spring 25 is in its natural state, it generates an upward elastic force on the abutment 23. When there is no external force intervention, it can push the abutment 23 and the locking tongue 24 to reset, ensuring that the locking tongue 24 is stably inserted into the locking groove 27. The bottom front end of the collection box 21 has a locking groove 27. The position and size of the locking groove 27 match the locking tongue 24. When the collection box 21 is fully pushed into the designated position inside the collection bracket 20, the locking tongue 24 can be accurately aligned and inserted into the locking groove 27. The locking tongue 24 is inserted into the locking groove 27. Through the insertion and cooperation of the two, the collection box 21 is firmly fixed in the collection bracket 20, preventing the collection box 21 from being displaced or falling out due to vibration during the operation of the device.

[0035] Reference Figures 1-3An electric push rod 13 is fixedly connected to the top of the main frame 1. The electric push rod 13 is vertically installed at the center of the top of the main frame 1, with its output end facing downward and connected to the tool 14. It can output a stable thrust to drive the tool 14 to move up and down. The output end of the electric push rod 13 is threadedly connected to the tool 14. The threaded connection method allows the operator to quickly disassemble the old tool 14 and replace it with a new tool 14 according to different drilling diameter requirements. At the same time, it ensures that the tool 14 is firmly connected to the output end of the electric push rod 13, and avoids the tool 14 from loosening during drilling, which would affect the machining accuracy.

[0036] Reference Figures 1-3 The guide post 7 is slidably connected inside the support arm 2. The guide post 7 passes through the support arm 2 and can slide along the preset through hole inside the support arm 2, further enhancing the guiding effect on the up and down movement of the pressure plate 12, preventing the pressure plate 12 and the threaded rod 11 from rotating together with the bevel gear 10, ensuring that the pressure plate 12 always remains horizontal during the movement, and avoiding uneven pressing of the foot pad due to the tilt of the pressure plate 12.

[0037] Reference Figures 1-3 The cutting tool 14 is slidably connected to the inner wall of the round hole 18. When the cutting tool 14 moves downward under the drive of the electric push rod 13, it can slide precisely along the inner wall of the round hole 18, effectively preventing the cutting tool 14 from deviating during the drilling process and ensuring that the accuracy of the machined hole position meets the requirements.

[0038] Reference Figures 1-3 The handle 6 is rotatably connected to the inside of the support arm 2. One end of the handle 6 extends into the inside of the support arm 2 and is fixed to the bevel gear 5, while the other end is exposed on the outside of the support arm 2. When the operator rotates the handle 6 on the outside of the support arm 2, the bevel gear 5 can be directly driven to rotate inside the ring bracket 4. Power transmission can be achieved without disassembling the parts, making the operation simple and convenient.

[0039] Reference Figures 4-5 One end of the spring 25 is fixedly connected to the bottom of the abutment plate 23, and the other end of the spring 25 is fixedly connected to the inner wall of the lock housing 22. This method of fixing at both ends ensures that the spring 25 will not fall out of the lock housing 22 during the extension and retraction process, and can always provide a stable elastic restoring force for the abutment plate 23, ensuring the reliability of the locking structure. The end of the latch 24 away from the abutment plate 23 is fixedly connected to a pull plate 26, which extends to the outside of the lock housing 22. By pulling the pull plate 26 downward, the operator can drive the latch 24 and the abutment plate 23 to move downward synchronously, thereby compressing the spring 25 and causing the latch 24 to disengage from the lock groove 27, making it convenient to quickly open the collection box 21 for waste cleaning.

[0040] Working principle: First, the mold 17, which is compatible with the model of the foot pad to be processed, is slid into the inner wall of the square groove 15 inside the main frame 1 through the four grooves 19 on the outer wall of the mold 17. Then, the operator rotates the handle 6 inside the support arm 2. The handle 6 drives the bevel gear 5 to rotate. The bevel gear 5 meshes with the bevel gear 10, which in turn drives the threaded rod 11 inside the bevel gear 10 to move downward in the vertical direction. At the same time, the two guide posts 7 at the top of the pressing plate 12 slide along the inside of the support arm 2 to ensure that the pressing plate 12 does not rotate with the bevel gear 10. Then, the electric push rod 13 fixed at the top of the main frame 1 is started. Its output end drives the cutter 14 to move downward. The cutter 14 achieves precise drilling of the foot pad. The waste generated during the drilling process will naturally fall into the collection box 21 inside the collection bracket 20 fixed at the bottom wall of the main frame 1.

[0041] When the waste material in the collection box 21 accumulates to a certain amount, the operator pulls down the pull plate 26 extending from the outer lock shell 22 of the collection box 21. The pull plate 26 drives the lock tongue 24 and the abutment plate 23 fixed to the lock tongue 24 to slide down along the inner wall of the lock shell 22, compressing the spring 25 sleeved on the outside of the lock tongue 24, causing the lock tongue 24 to disengage from the lock groove 27 at the bottom front end of the collection box 21. At this time, the collection box 21 can be pulled out along the internal track of the collection bracket 20 to clean up the waste material. After cleaning, the collection box 21 is pushed back to the original position of the collection bracket 20. The spring 25 resets and pushes the abutment plate 23 and the lock tongue 24 to move upward. The lock tongue 24 is re-inserted into the lock groove 27, and the collection box 21 is firmly fixed in the collection bracket 20. This completes a complete car floor mat processing and drilling operation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
