[0019] 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.

[0020] like Figures 1 to 4 As shown, a multifunctional scraper comprises a shell 1, a telescopic slot 2 is provided on the front of the shell 1, a slider 3 is slidably connected to the inside of the telescopic slot 2, a knife slot 4 is provided on the front of the slider 3, a blade 5 is slidably connected to the inside of the knife slot 4, a first cylinder 6 and a first spring 7 are fixedly connected to the rear side of the bottom wall of the telescopic slot 2, the first spring 7 is located inside the first cylinder 6, a first circular plate 8 is fixedly connected to the top of the first spring 7, the first circular plate 8 is slidably connected to the inner wall of the first cylinder 6, and the top of the first circular plate 8 is fixedly connected to the first spring 7. An insert block 9, a shift groove 10 is provided on the surface of the shell 1, a circular hole is provided on the surface of the slider 3, the first insert block 9 extends through the circular hole to the top of the slider 3 and is slidably connected thereto, a fixing ring 11 is fixedly connected to the top of the slider 3, the interior of the fixing ring 11 is communicated with the circular hole, a pressure column 12 is provided inside the fixing ring 11, a pressure plate 13 is fixedly connected to the bottom of the pressure column 12, the pressure plate 13 is slidably connected to the inner wall of the fixing ring 11, a shift block 14 is fixedly connected to the top of the pressure column 12, and a hanging hole 21 is provided on the rear side of the surface of the shell 1.

[0021] refer to Figure 2 The middle part of the bottom wall of the telescopic groove 2 is fixedly connected with a second cylinder 15 and a second spring 16, the second spring 16 is located inside the second cylinder 15, the top of the second spring 16 is fixedly connected with a second circular plate 17, the second circular plate 17 is slidably connected to the inner wall of the second cylinder 15, the top of the second circular plate 17 is fixedly connected with a second plug-in block 18, and the top of the second plug-in block 18 is in contact with the slider 3.

[0022] As a technical optimization solution of the present invention, through the setting of the second plug block 18, when the blade 5 needs to be extended to scrape glue, the shift block 14 is pressed downward, so that the pressure column 12 drives the pressure plate 13 to squeeze the first plug block 9 downward, so that the first plug block 9 is out of the circular hole, and the shift block 14 can be pushed to slide the slider 3 forward to extend the blade 5 out of the telescopic slot 2. Since the second spring 16 is in a compressed state, when the second plug block 18 coincides with the circular hole on the surface of the slider 3, the second spring 16 will stretch and push the second plug block 18 through the circular hole into the interior of the fixing ring 11 for fixing, so that the blade 5 will not slide when scraping glue, making its operation more stable.

[0023] refer to Figure 1 and Figure 2 The surface of the shell 1 is provided with an anti-slip sleeve 19, and both sides of the anti-slip sleeve 19 are fixedly connected with a plurality of anti-slip strips 20, and the anti-slip strips 20 are in a linear array.

[0024] As a technical optimization solution of the present invention, the provision of the anti-slip sleeve 19 and the anti-slip strip 20 greatly increases the friction between the housing 1 and the hand, making the housing 1 more stable and comfortable when held.

[0025] refer to Figure 2 and Figure 4 The surfaces of the first plug-in block 9 and the second plug-in block 18 are both configured as inclined surfaces, and the inclined surfaces are both inclined toward the rear side.

[0026] As a technical optimization solution of the present invention, by setting the inclined surface, when the slider 3 slides backward, there is no need to press the second plug-in block 18 and the first plug-in block 9 downward. The slider 3 can squeeze the first plug-in block 9 and the second plug-in block 18 downward along the inclined surfaces, further facilitating the use of the user.

[0027] refer to Figure 2 and Figure 3 The rear end of the blade 5 is fixedly connected with an anti-slip block 22, the cross-sectional area of ​​the anti-slip block 22 is larger than the cross-sectional area of ​​the blade 5, and the anti-slip block 22 is located inside the knife groove 4 and is slidably connected thereto.

[0028] As a technical optimization solution of the present invention, the provision of the anti-slip block 22 makes the blade 5 more stable and prevents it from sliding at will. After separating the slider 3 from the second insertion block 18, the shift block 14 is pushed to slide the slider 3 forward, exposing the knife groove 4 to the outside of the telescopic slot 2. Then, the blade 5 is slid to the left or right, and the blade 5 can be taken out for replacement. The replacement is simple and convenient, thereby avoiding affecting the work efficiency.

[0029] refer to Figure 3 and Figure 4The interior of the fixing ring 11 is fixedly connected with an anti-slip ring 23 , the fixing ring 11 is located inside the anti-slip ring 23 and is slidably connected thereto, and the diameter of the pressure column 12 is smaller than the diameter of the pressure plate 13 .

[0030] As a technical optimization solution of the present invention, the anti-slip ring 23 is set to limit the pressure column 12, thereby preventing the pressure column 12 from separating from the fixing ring 11 and causing the shift block 14 to fall off, making the rubber scraper more stable when working.

[0031] The working principle and use process of the present invention are as follows: when in use, when the user needs to extend the blade 5 to scrape glue, the user presses the shift block 14 downward, so that the pressure column 12 drives the pressure plate 13 to squeeze the first plug 9 downward, so that the first plug 9 is out of the round hole, and the shift block 14 can be pushed to slide the slider 3 forward to extend the blade 5 out of the telescopic slot 2. Since the second spring 16 is in a compressed state, when the second plug 18 coincides with the round hole on the surface of the slider 3, the second spring 16 will stretch, and the second plug 18 is pushed into the interior of the fixing ring 11 through the round hole for fixing, and then the glue can be scraped. When the blade 5 needs to be replaced, the shift block 14 is pressed downward so that the second plug 18 and The circular hole on the surface of the slider 3 is disengaged, and the shift block 14 is pushed to slide the slider 3 forward, exposing the knife groove 4 to the outside of the telescopic slot 2. The blade 5 is then slid to the left or right to take out the blade 5 for replacement. When the blade 5 needs to be retracted into the telescopic slot 2, the shift block 14 is continuously pressed downward and the slider 3 is pushed backward until the circular hole on the surface of the slider 3 coincides with the first insertion block 9, and then the shift block 14 is released. At this time, the first spring 7 will stretch to extend the first circular plate 8 and the first insertion block 9, so that the first insertion block 9 slides into the interior of the fixing ring 11 through the circular hole, thereby fixing the slider 3 so that the blade 5 will not extend out at will to cut the user, thereby greatly improving its safety.
