The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1 to 6The present invention preferably provides the following technical solution: a cutting tool changing module for polishing a cutting board, comprising: a U-shaped frame 111; an assembly assembly disposed on the top of the U-shaped frame 111 for connecting to the execution end of a driving device; and a switching fixture staggered and symmetrically installed on opposite sides of the U-shaped frame 111, wherein a plurality of polishing modules are installed between the switching fixtures, wherein the plurality of polishing modules are used to install different types of polishing molds, and under the drive of the switching fixtures, the plurality of polishing modules always switch positions in a horizontal state; the switching fixture includes rotating shafts 112 respectively rotatably installed on opposite ends of the U-shaped frame 111, and two cross mounting brackets 113 staggeredly distributed on opposite ends of the two rotating shafts 112, and the two cross mounting brackets 113 are assembled with the plurality of polishing modules one by one through a plurality of sets of pins 114 rotatably installed on their opposite ends.

[0025] The driving device of this application can be a motor, a handle, etc., to realize both electric and manual driving modes;

[0026] The switching fixture set on the opposite side of the C-shaped frame 111, combined with Figure 1 , 2 As shown, the two cross-shaped mounting brackets 113 are rotatably mounted on opposite sides of the U-shaped frame 111 via rotating shafts 112, and are staggered and symmetrically distributed. Simultaneously, several sets of pins 114 at the opposite ends of the two cross-shaped mounting brackets 113 are used to mount polishing modules. When the two cross-shaped mounting brackets 113 rotate, the polishing modules can always switch positions in a horizontal state, ensuring that when each polishing module is switched to the lower part of the device, its operating end always remains downward and horizontal. Figure 2 , 6 As shown, this design is intended for polishing the work surface. Firstly, it ensures a uniform and consistent polishing effect with high surface quality. Secondly, it reduces adjustment and rework time, guarantees smooth polishing, and improves polishing efficiency.

[0027] Furthermore, each polishing module includes an assembly box 211 fixed on two pins 114, and a first slot 212 and a second slot 213 respectively disposed on the upper and lower parts of the assembly box 211 for assembling the polishing mold; further, the polishing mold includes a spare mold 214 and a working mold 215 respectively limited and embedded in the first slot 212 and the second slot 213, wherein the operating end of the working mold 215 faces downward and extends into the second slot 213.

[0028] On one of the opposite ends of the two cross-shaped mounting brackets 113, a pin 114 is rotatably mounted and fixed to an assembly box 211, which is then combined with... Figure 1 , 2As shown in Figure 3, two pins 114 are fixed on the front and rear sides of the assembly box 211 to ensure the stability of the assembly box 211. When the two staggered and symmetrically distributed second slots 213 rotate in the same direction, the pins 114 rotate adaptively, so that the assembly box 211 can remain in a horizontal state. Then the polishing mold assembled inside the assembly box 211 can always switch positions in a horizontal state and ensure the uniformity of polishing when working in the working position.

[0029] In order to further improve the functionality of this device, the single polishing mold set in this application consists of a spare mold 214 and a working mold 215. It is known that several sets of polishing molds are of different types, and can be selected as polishing blades (for wooden and bamboo cutting boards), sandpaper, sanding stone, polishing disc (with soft pad or cloth wheel) etc. (for stainless steel and PP / PE plastic cutting boards).

[0030] The spare mold 214 and working mold 215, which contain individual polishing molds, are of the same type but have different grit sizes to meet different polishing needs.

[0031] Furthermore, each assembly box 211 is also provided with a pin structure for reinforcing the spare mold 214 and the working mold 215; the pin structure includes a first insertion hole 216 respectively opened on the spare mold 214 and the working mold 215; a second insertion hole opened on the assembly box 211 and corresponding to the first insertion hole 216; and a plug bar 218, wherein one end of the plug bar 218 passes downward through the second insertion hole and the first insertion hole 216 respectively, and the other end is rotatably mounted with a lever 219. When the lever 219 is perpendicular to the cross-section of the plug bar 218 and abuts against the assembly box 211, it is used for reinforcing the spare mold 214 and the working mold 215; when the lever 219 is parallel to the plug bar 218, it is used for disassembling the spare mold 214 and the working mold 215.

[0032] To ensure the stability of polishing the spare mold 214 and the working mold 215, this application provides a pin structure on the assembly box 211. When the pin structure's insert 218 passes downwards sequentially through the upper part of the assembly box 211, the spare mold 214, the middle part of the assembly box 211, and the working mold 215, the spare mold 214 and the working mold 215 can be limited in the front-back direction. Furthermore, the shape and characteristics of the first slot 212 and the second slot 213 also limit the spare mold 214 and the working mold 215 in the up-down and left-right directions. Figure 4 , 5 As shown.

[0033] Furthermore, a groove 217 is provided on the top of the assembly box 211 corresponding to the position of the second insertion hole. When the lever 219 is parallel to the plug bar 218, the groove 217 facilitates the lifting of the lever 219. Figure 5 As shown.

[0034] Furthermore, the C-shaped frame 111 is also provided with a steering wheel assembly for switching tooling drive. The steering wheel assembly includes a turntable 1151 fixed to one end of one of the rotating shafts 112 away from the cross mounting bracket 113.

One end of the limiting post 1154 can engage with any one of the limiting grooves 1152, and a spring 1155 is connected between the other end and the inner wall of the mounting frame 1153.

[0035] like Figure 3 As shown, the limiting post 1154 provided in the mounting frame 1153 can extend into one of the limiting grooves 1152 opened on the turntable 1151. The turntable 1151 is fixed to one of the rotating shafts 112. Therefore, when the turntable 1151 is rotated, and the polishing modules on the two cross mounting brackets 113 complete the position switching, the limiting post 1154 is driven to engage with one of the limiting grooves 1152, and the position of the polishing module can be fixed.

[0036] Furthermore, the assembly assembly includes support plates 311 fixed on both sides of the U-shaped frame 111, and an assembly block 312 fixed on the upper part of the opposing surfaces of the two support plates 311; an assembly groove 313 and a through groove 314 respectively opened inside and at the bottom of the assembly block 312; and screw holes 315 respectively opened on the two assembly grooves 313, with the ends of the screw holes 315 extending into the assembly grooves 313.

[0037] This application presents a fixedly installed support plate 311 and assembly block 312. The assembly slot 313 opened on the assembly block 312 engages with the handle, and the bolt passes through 315 to achieve fixation. The device can then be manually operated for polishing. Manual operation is suitable for the use of polishing blades, sandpaper, and abrasive stone slabs.

[0038] When the through slot 314 in the middle of the assembly block 312 is fitted into the output shaft of the motor, and the device is fixed to the output shaft of the motor by passing bolts through the screw hole 315, the motor can run to realize the electric polishing of this device. The electric operation is suitable for the use of sandpaper, abrasive stone slabs and grinding discs.
