Description

Technical Field

[0001] The utility model relates to the technical field of scraper blades, in particular to a cleaning scraper blade. Background Art

[0002] Most blade replacement methods involve loosening two screws to release the blade or loosening a single knob and pressing the back to release the blade.

[0003] Most of the existing cleaning blades use a metal piece at the tail to knock on hard objects or a hammer to hammer the tail to achieve the purpose of cleaning hard objects. At present, cleaning blades with built-in hard object and stubborn dirt processing functions usually use the blade to directly hit the edge of the hard object to pry the dirt to achieve the purpose of cleaning. In the case of difficult prying, the tail of the blade is hammered to insert the blade into the edge of the hard object to pry the dirt to achieve the purpose of cleaning. When the edge of the hard object cannot be inserted, the tail is used to knock the hard object or other tools such as a hammer are used to hammer the hard object to achieve the purpose of breaking the hard object for easy removal. This processing method requires the use of more than two tools to handle the hard object, and when the tail of the blade is hammered to hit the hard object, the blade is pointed upward and there may be a risk of injury to people. Therefore, those skilled in the art provide a cleaning blade to solve the problems raised in the above background technology. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting a raised knocking part, hard objects that are difficult to remove can be knocked and destroyed to achieve the purpose of cleaning. During operation, when the hand swings the scraper tool by holding the handle, the action is consistent with the force application process during knocking, and the operation is more labor-saving. During the knocking process, the blade is always facing outward, and its blade edge will not face the human face, which is safer. The corners of the blade will not contact hard objects, which can increase the service life of the blade.

[0016] 2. By setting two threaded mounting grooves of different depths and using one of them to connect with the rear end of the shank through a thread, the overall length of the scraper tool can be adjusted. When the overall length is longer, it is more labor-saving, and when the overall length is shorter, it is more space-saving.

[0017] 3. The blade is fixed by setting a knob. When replacing the blade, the knob can be turned. Under the elastic force of the spring, the knob will be lifted up a certain distance. During this process, the blade is still clamped by the cutter head and the clamping plate, which can prevent the blade from moving around or falling off accidentally. Only by pressing the knob to compress the spring can the blade fall off, and by turning the knob in the opposite direction, the clamping plate and the cutter head can the newly replaced blade be clamped and fixed. The operations of loosening, tightening, and pressing the knob are all performed on the front of the cutter head, without the need for extra flipping and identification operations, and are more convenient to operate.
