DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In one embodiment, a multifunctional cleaning blade is provided. Figure 1-4As shown, the multifunctional cleaning scraper includes a blade head 1 and a gripping rod 2. The blade head 1 is mounted on the front end of the gripping rod 2. The blade head 1 is used to scrape off the surface layer when cleaning, such as scraping off the old wall surface paint layer during renovation. The gripping rod 2 is used as a gripping portion. The blade head 1 includes a connecting rod portion 11 at the rear and a blade clamping plate portion 12 at the front. The connecting rod portion 11 is used to connect to the front end of the gripping rod 2. The blade clamping plate portion 12 is provided with a replaceable blade 13. The replaceable blade 13 means that the entire blade 13 can be disassembled and replaced. Because as a cleaning scraper, it needs to be in constant contact and friction with the surface of the wall, etc., the blade 13 is a wear part and needs to be replaced from time to time. The gripping rod 2 is also detachably connected to the connecting rod portion 11 at the rear of the cutter head 1, so that the gripping rod 2 can be removed to repair the blade 13 on the cutter head 1, wherein the blade 13 is a utility knife that can be cut off in sections. This type of utility knife is very common on the market, that is, a pre-processed cutting mark is provided at each interval on the knife body. The cutting mark will not easily cause the blade 13 to break during use, but the blade 13 can be cut off along the cutting mark on it by applying force with a tool. Such a utility knife is actually intended to be cut off when the cutter head is worn in order to form a new cutter head, and in this embodiment In this example, the purpose of truncation is to match the length of the blade 13 with the width of the blade clamping portion 12 to prevent the two ends of the blade 13 from being exposed. If the two ends of the blade 13 are exposed, the ends of the blade 13 may interfere with other areas outside the working surface when the multifunctional cleaning scraper is used. For example, when the multifunctional scraper is used to scrape off the old wall surface paint layer during renovation, if the two ends of the blade 13 are exposed, when the multifunctional cleaning scraper is used to scrape off the wall skin at the bottom of the wall, the ends of the blade 13 may poke the ground and damage the floor tiles. A screwdriver 3 is provided in the gripping rod 2, and the screwdriver 3 can be removed from the gripping rod 2. The front end of the screwdriver rod of the screwdriver 3 is provided with a clamping edge for cutting off the blade 13. The end of the blade 13 is clamped in the clamping edge, and the gripping rod 2 is bent to one side to break off a section of the blade 13.

[0024] Furthermore, in another embodiment, Figure 1-4 As shown, the front end of the blade clamping plate portion 12 of the multifunctional cleaning blade is provided with a blade slit 121, the top and left and right sides of the blade slit 121 are slits, and the lower side of the blade 13 is clamped in the blade slit 121, and the gap of the blade slit 121 is slightly wider than the thickness of the blade 13; a through screw hole 122 is provided on the lower side of the blade slit 121, and a bolt component is passed through the screw hole 122 to narrow the blade slit 121 by the bolt component to clamp the blade 13.

[0025] Furthermore, in another embodiment, Figure 1-4As shown, the bolt assembly of the multifunctional cleaning blade includes a stud 123, with a nut 124 provided on both sides of the stud 123. This allows the corresponding nuts to be tightened on both sides of the stud 123 to prevent a single nut from being threaded and unable to be tightened. Of course, in other embodiments, a bolt assembly consisting of a screw and a nut may also be used.

[0026] Furthermore, in another embodiment, Figure 1-4 As shown, the connecting rod portion 11 at the rear of the blade head of the multifunctional cleaning blade is provided with a first internal thread, and the front end of the holding rod 2 is correspondingly provided with a first external thread. The holding rod 2 is screwed to the connecting rod portion 11, and the connecting rod portion 11 is a hollow structure that can accommodate the front end of the screwdriver 3.

[0027] Furthermore, in another embodiment, Figure 1-2 As shown, the screwdriver 3 of the multifunctional cleaning scraper includes a handle 31 and a screwdriver rod 32. The thickness of the handle 31 matches the gripping rod 2. The gripping rod 2 is provided with a hollow section from the lower end to the upper end for accommodating the screwdriver rod 32. The lower part of the gripping rod 2 is provided with a second internal thread, and the front end of the handle 31 is correspondingly provided with a second external thread 311. The handle 31 is screwed onto the rear part of the gripping rod 2 to constitute a part of the gripping rod 2. At this time, the screwdriver rod 32 is located in the hollow section.

[0028] Furthermore, in another embodiment, Figure 1-4 As shown, the top end of the screwdriver rod 32 of the multifunctional cleaning scraper has a flat blade, a clamping edge 321 is located in the middle of the flat blade, and the bottom end of the screwdriver rod 32 has a cross blade. The screwdriver rod 32 can be removably installed in the handle 31 to allow for the use of different screwdriver blades. When the flat blade end of the screwdriver rod 32 is inserted into the handle 31, the cross blade can be used. When the cross blade end of the screwdriver rod 32 is inserted into the handle 31, the flat blade can be used. Thus, the multifunctional cleaning scraper can be used not only as a cleaning tool, but also as a screwdriver.

[0029] Furthermore, in another embodiment, Figure 1-2 As shown, the gripping rod 2 of the multifunctional cleaning blade is provided with anti-skid lines so as to prevent loosening during gripping. In addition, the gripping rod 2 is gradually thickened from top to bottom, which is conducive to gripping the gripping rod 2 tightly.

[0030] Furthermore, in another embodiment, Figure 4 As shown, the multifunctional cleaning scraper also includes a long rod 4 that can be detachably connected to the connecting rod portion 11 at the rear of the blade head.
