[0020] A trimming blade 10 is detachably mounted on the outer wall of the other side of the guide column 8 through a connecting piece 9. When the ceramic clay blank rotates, the blade of the trimming blade 10 applies appropriate force and angle to the surface of the blank to remove or scrape off excess ceramic material. An elastic support structure 7 for forcing the guide column 8 to move outward and reset is installed inside the base 1.

[0021] The connecting rod support structure is an H-shaped main connecting rod 4 installed on one side of the top end of the inverted T-shaped seat 3, and a secondary connecting rod 5 hinged at one end of the H-shaped main connecting rod 4 away from the inverted T-shaped seat 3, the bottom end of the secondary connecting rod 5 is fixedly connected to the top end of the guide column 8, one end of the surface of the secondary connecting rod 5 is hinged with a C-shaped joint 6, and the end of the C-shaped joint 6 away from the secondary connecting rod 5 is connected to the movable end of the elastic support structure 7;

[0022] The elastic support structure 7 includes an inner hollow cylinder 701 fixed inside the base 1, and a guide rod 704 slidably installed inside the inner hollow cylinder 701, one end of the guide rod 704 is fixedly connected to one end of the C-shaped joint 6, and a support plate 703 is fixed to the other end of the guide rod 704, and a coil spring 702 is installed on the outer wall of the support plate 703 away from the guide rod 704, and the top of the coil spring 702 is fixedly connected to the inner wall of one side of the inner hollow cylinder 701. When the user pushes the guide column 8 and the trimming blade 10 to swing outward or inward through the finger ring 11, the top of the auxiliary connecting rod 5 swings with one end of the H-shaped main connecting rod 4 as the center of the circle, and the auxiliary connecting rod 5 pushes the support plate 703 to slide through the C-shaped joint 6 and the guide rod 704, and the coil spring 702 is compressed inside the inner hollow cylinder 701;

[0023] When the user's fingers no longer apply force to the finger ring 11 and the guide column 8, the coil spring 702 forces the components to reset. Compared with relying on the strength of the upper arms and upper limbs, the fingers gradually control the movement of the trimming tool, which can reduce the user's fatigue. Less force is required for fine-tuning and control. During the long trimming process, the user is more likely to maintain a good operating state and is less likely to experience fatigue and hand discomfort.

[0024] The connecting member 9 includes a plane portion 901 disposed on an outer wall of one side of the guide column 8, and a U-shaped guide bar 902 fixed on the plane portion 901, a trimming blade 10 is inserted into the interior of the U-shaped guide bar 902, and a bolt 903 for bolting the trimming blade 10 is installed on an outer wall of one side of the U-shaped guide bar 902, and the length of the U-shaped guide bar 902, the trimming blade 10 and the guide column 8 are equal;

[0025] When the trimming blade 10 is worn or otherwise damaged, the user can tighten the bolt 903 so that the bolt 903 is withdrawn to the outside of the U-shaped guide bar 902 and the trimming blade 10, thereby releasing the bolt connection restriction between the trimming blade 10 and the U-shaped guide bar 902, and then install a new trimming blade 10 in the U-shaped guide bar 902, thereby making it convenient for the user to replace the worn trimming blade 10 in a timely manner.

[0026] When using the embodiment of the present application, the user first holds the trimming tool through the right-angle grip 2, so that the trimming blade 10 is facing the ceramic clay blank, and the user's fingers buckle the finger ring 11. When the trimming tool needs to be brought close to the ceramic clay blank, the user drives the trimming tool to move and position it near the outer wall of the ceramic clay blank through the strength of his own upper limbs, upper arms and forearms. When the clay blank needs to be corrected, the user ensures the stability of his own upper limbs, upper arms and forearms, and the user's fingers push the finger ring 11, the guide column 8 and the trimming blade 10 outward, so that the blade part of the trimming blade 10 gradually approaches the ceramic clay blank. When the ceramic clay blank rotates, the blade part of the trimming blade 10 is used to apply appropriate force and angle on the surface of the blank to cut or scrape off excess ceramic material. When this part of the ceramic clay blank is After the material is corrected, the user still keeps the upper limbs stable and pulls the fingers toward the inside of the right-angle grip 2, and then the user's fingers pull the guide column 8, the trimming blade 10 and the auxiliary connecting rod 5 toward the base 1 through the finger ring 11, and the elastic support structure 7 is in a moving and compressed state under the action of the C-joint 6, and the H-shaped main connecting rod 4 supports the swing of the C-joint 6 and the auxiliary connecting rod 5. Then the ceramic trimming tool can gradually control its own movement through the user's fingers, and the user can achieve more precise control. The flexibility and sensitivity of the fingers enable the user to more accurately perceive the surface details and shape changes of the ceramic body, thereby making more precise adjustments during the trimming process, allowing the user to use the trimming tool more flexibly to create more unique and individual textures, curves and shapes.
