Abstract
An adhesive substance removing tool is provided with a cracking tool and a scrapping assembly which are removably coupled to a base. The cracking tool is used to crack the adhesive substance by forming breaking lines on the surface of the adhesive substance, and then the scrapping assembly is used to scrape off the adhesive substance by starting from the breaking lines. The combination of the cracking tool and the scraping assembly allows the user to remove adhesive substance easily and completely. Besides, the cutting assembly of the cracking tool is able to move freely both in straight-line or circular fashion, and the cracking tool can be prevented from rotating or disengaging once it is positioned in place on the base. Hence, convenience and safety of use can both be assured.
Claims4
An adhesive substance removing tool comprising:
- a base formed with an assembling chamber, and an outer periphery of the assembling chamber protruding upward to form a jaw portion and a tail portion;
- wherein
- the assembling chamber includes a bottom surface, an opening and an inner peripheral surface between the bottom surface and the opening, at the bottom surface are formed a guide protrusion and an assistant protrusion, the bottom surface is provided with a first elastic portion around the guide protrusion and a second elastic portion around the assistant protrusion, each of the first and second elastic portions includes two opposite slits and a slot, the slot is in communication with the slits and extends between the bottom surface and the inner peripheral surface, the two slits penetrate the bottom surface and cooperate with the slot to define a U-shaped gap, so as to make a portion of the bottom surface surrounded by the U-shaped gap elastic, the inner peripheral surface of the assembling chamber is provided with a first threaded section and a second threaded section;
- a scrapping assembly including a blade holder and a blade mounted on the blade holder, and the blade holder being disposed on the jaw portion of the base;
- and
- a cracking tool including a cover and a cutting assembly, the cover being formed with a receiving chamber and a terminal periphery, in the receiving chamber being disposed a center shaft, and around the terminal periphery being formed a first positioning concave and a second positioning concave, on an outer surface of the cover being formed a first helical protrusion and a second helical protrusion, the cutting assembly being provided with a sleeve, a double-cutter shaft and two cutting rollers, the sleeve being provided with an extension arm to pivotally connect the double-cutter shaft, the two cutting rollers being pivotally connected to two ends of the double-cutter shaft, the sleeve being pivotally sleeved onto the center shaft and fixed thereon by inserting the positioning member into the center shaft, and the cutting assembly partially protruding out of the terminal periphery, after the cutting assembly is positioned on the cover, the first and second helical protrusions of the cover are screwed with the first and second threaded sections of the base, and the guide protrusion and the assistant protrusion of the base are restricted in the first and second positioning concavities of the cover, respectively.
