[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Due to the structural differences between prefabricated wall panels, wall panels and columns, wall panels and floor slabs, etc., in actual operations, in order to ensure the flatness of the walls of prefabricated buildings, construction workers often need to use scrapers to scrape off the protruding parts of the sealant used for caulking or leveling. Existing scrapers are all integrated structures, that is, the handle and the scraper blade are fixed together, and the scraper blade cannot be removed from the handle. The overall length is long, and it takes up a large space when carrying and storing, which is not convenient to carry. Utility Model Content

[0021] Please refer to Figure 1 and Figure 2 The present invention is a scraper knife 100 that is easy to disassemble and carry. The scraper knife 100 that is easy to disassemble and carry includes a handle cover 20, a clamping tube 30 with one end sleeved in the handle cover 20, a locking tube cap 40 adapted to the clamping tube 30, and a scraper blade 50 that is clamped and fixed on the clamping tube 30 and extends from the locking tube cap 40. The clamping tube 30 is provided with four external threaded tube parts 31, a guide block 32 connected to one end of the external threaded tube part 31 away from the handle cover 20, and a clamping gap 33 is formed between adjacent external threaded tube parts 31. The inner wall of the locking tube cap 40 is provided with an internal thread 41 and a first guide tapered surface 42, and the first guide tapered surface 42 is adapted to the guide block 32 and is located on the end of the locking tube cap 40 away from the handle cover 20.
[0022] Furthermore, the handle sleeve 20 is provided with a mounting hole 21, and the clamping tube 30 is provided with a mounting rod 34 connected to the external threaded tube 31, and the mounting rod 34 is located in the mounting hole 21. Furthermore, the mounting rod 34 is provided with a second guide tapered surface 35, and the second guide tapered surface 35 is located on one end of the mounting rod 34 away from the external threaded tube 31, so that the handle sleeve 20 and the clamping tube 30 can be quickly disassembled or installed.
[0023] Furthermore, a plurality of anti-skid ridges 22 are provided on the outer wall of the handle cover 20, and the anti-skid ridges 22 are arranged along the circumference of the handle cover 20. The anti-skid ridges 22 extend along the length direction of the handle cover 20, and the cross-sectional width of the anti-skid ridges 22 gradually increases from the end close to the locking cap 40 to the end away from the locking cap 40. The provision of the anti-skid ridges 22 can increase the stability of the handle cover 20 when held by hand, and avoid slipping and rotation during the scraping operation, which affects the quality of the scraping operation. In order to increase the practicality of the handle cover 20, a bulge 23 is provided on the handle cover 20, and the bulge 23 is located on the end of the handle cover 20 away from the locking cap 40.
[0024] Furthermore, a limiting step 36 is provided on the mounting rod 34, and the limiting step 36 is located on one end of the mounting rod 34 close to the external threaded tube 31. In this embodiment, the limiting step 36 is arranged in a circular ring shape, and the mounting rod 34 can be limited by the setting of the limiting step 36 to avoid excessive insertion of the handle cover 20 and damage to the handle cover 20.
[0025] Furthermore, a through hole 51 is provided on the scraper blade 50. The through hole 51 is located on one end of the scraper blade 50 close to the handle sleeve 20. Figure 3 Through the setting of the perforation 51, it is convenient to store the scraper blades 50 of different sizes that can be used together with each other with a rope, so that they can be taken out immediately for subsequent use.
[0026] The above-mentioned scraper blade 100, which is easy to disassemble and carry, is assembled by the handle cover 20, the clamping tube 30, the locking tube cap 40, and the scraper blade 50. When in use, it is only necessary to insert the scraper blade 50 from the locking tube cap 40 into the clamping tube 30 so that both ends of the scraper blade 50 are located in the clamping gap 33, and then twist the locking nut 40 toward the end close to the handle cover 20, and the locking nut 40 will move toward the handle cover 20 on the external threaded tube portion 31. As the movement goes deeper, the first guide cone surface 42 abuts against the guide block 32, forcing the clamping gap 33 to continuously shrink until the scraper blade 50 is clamped and fixed. When the scraper blade 50 needs to be disassembled, it is only necessary to twist it toward the end away from the handle cover 20 until the clamping gap 33 is restored to a thickness greater than the scraper blade 50, and then the scraper blade 50 is pulled out to complete the disassembly. The scraper knife 100, which is easy to disassemble and carry, can be disassembled and assembled according to actual needs, takes up less space when carried and stored, and is very practical. Moreover, when the original scraper blade 50 is damaged and needs to be replaced, or a new size scraper blade 50 needs to be replaced to adapt to a new working scene, the scraper blade 50 can be quickly replaced without scrapping other parts, and use will not cause waste.
