The part of the knife body inserted into the receiving cavity has a fixing hole, and the fixing hole penetrates the knife body. The handle has a fixing column at the part of the receiving cavity, and the two ends of the fixing column are respectively connected with the two side walls of the receiving cavity. The fixing column is matched with the fixing hole, and the fixing column is inserted into the fixing hole and connected with the knife body. The end of the knife body away from the handle is a hook structure, the hook structure is curved near the handle, and the inner edge of the hook structure is provided with a blade. The above-mentioned edge trimming knife has poor practicability because the knife head position is worn after long-term use, and the knife head cannot be conveniently replaced. SUMMARY
[0004] The utility model discloses a wheel cover edge trimmer with higher practicability. The first knife head and the second knife head are stably installed on the knife handle through the cooperation of the clamping columns and the clamping grooves, and the first knife head and the second knife head can be conveniently replaced and repaired on the knife handle, so that the utility model has higher practicability.
[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of a wheel cover edge trimmer, which includes a knife handle and first and second knife heads arranged at the two ends of the knife handle. The first and second knife heads are provided with clamping columns, and the knife handle is provided with clamping grooves matched with the clamping columns.
[0006] The knife handle is also provided with fixing pins matched with the clamping columns.
[0007] The knife handle is provided with first through holes matched with the fixing pins, and the clamping columns are provided with second through holes matched with the fixing pins.
[0008] The first knife head is provided with a sharp end.
[0009] The second knife head is provided with a groove.
[0010] The end of the clamping column is provided with a rounded corner.
[0011] The knife handle is provided with a protective sleeve.
[0012] The beneficial effects of this utility model are:
[0013] The locking pins on the first and second cutting heads engage with the locking slots at both ends of the tool holder, thereby achieving stable installation of the first and second cutting heads on the tool holder and facilitating the replacement and repair of the first and second cutting heads on the tool holder, thus increasing their practicality.
[0014] The handle is also equipped with a fixing pin that engages with the locking post. The fixing pin ensures that the first and second cutting heads are stably placed on the handle, preventing them from falling off during use. Attached Figure Description
