[0025] Such as Figures 1 to 3As shown in the figure, the multi-functional caulking tool includes a handle 100, and a spatula 200, a corner spatula 300, a caulking press 400, and a caulking knife 500 are provided on the handle 100. The spatula 200 and the caulking press 400 are located at the head of the handle 100, and the caulking press 400 is located above the spatula 200. The corner spatula 300 and the caulking knife 500 are located at the tail of the handle 100, and the corner spatula 300 is located above the caulking knife 500. The spatula 200 is a common flat spatula for scraping work; the corner spatula 300 is a common triangular spatula, also known as a seam cleaning spatula, for removing glue at 90° corners; the caulking press 400 is used for caulking work; the caulking knife 500 is a caulking knife 500 for cleaning dust and cement in the gaps between tiles during tile caulking, and can also be used as a replacement for the glue nozzle dredging needle. In the caulking tool of this solution, a variety of tools are reasonably arranged, which can meet various requirements in caulking work, reduce the number of tools, and achieve multiple functions with one tool. In this embodiment, the spatula 200 is used as the first knife piece. Of course, the spatula can also be replaced with other caulking tools, such as a scraper and a wallpaper knife. The corner spatula 300 is used as the second knife piece and can be replaced with other tools for caulking, such as a seam cleaning cone.

[0026] See Figures 1 to 3 , a connecting portion 101 for installing the spatula 200 is provided at the head of the handle 100 and extends obliquely forward and downward. The spatula 200 is detachably installed at the front end of the connecting portion 101. A spatula cover for clamping the spatula 200 is further provided on the connecting portion 101, and the spatula cover can be installed by clamping in a manner of cooperation between a clamping block and a clamping groove. The structure of the spatula 200 belongs to the prior art and will not be described in detail here.

[0027] See Figure 1 and Figure 3 , inwardly recessed holding portions 102 are correspondingly provided on both sides of the handle 100. At the end of the holding portion 102 close to the spatula 200, anti-slip lines 103 are provided on the surface of the holding portion 102 to prevent slipping; the addition of the holding portion 102 makes it more convenient to hold and apply force, and the holding portion 102 can simultaneously meet the holding requirements for both spatula work and caulking work.

[0028] In this embodiment, the handle 100 has an open bottom and a cavity structure inside that can accommodate the caulking press 400 and the caulking knife 500. The left and right sides and the front connecting portion 101 of the handle 100 can all be integrally formed with the handle 100, and the material can be hard plastic.

[0029] See Figures 1 to 5, a front slot 104 is provided above the surface of the connecting part 101 and located above the blade part 200. The glue pressing part 400 is slidably installed inside the handle 100. The glue pressing part 400 can slide along the handle 100 to extend outside the front slot 104 or retract into the inside of the handle 100. When the glue pressing part 400 is in a fully retracted state, for the state, see Figures 1 to 3 , at this time, the glue pressing part 400 is completely hidden inside the handle 100, and scraping work can be carried out; when the glue pressing part 400 is in a fully extended state, for the state, see Figure 4 and Figure 5 , the front end of the glue pressing part 400 extends beyond the front end of the blade part 200, and glue pressing work can be carried out. Since the glue pressing part 400 is an in-built structure, the glue pressing part 400 and the blade part 200 share the same handle 100. After the glue pressing plate retracts into the handle 100, it is still operated by holding the handle 100, which can effectively prevent the glue pressing plate from being accidentally pushed out during force application and affecting the use of the tool. This in-built installation method ensures that the scraping work and the glue pressing work do not affect each other, improving the practicability and safety of tool use.

[0030] See Figure 1 , Figure 2 , Figure 4 and Figure 5 , the front slot 104 is a rectangular slot corresponding to the size of the glue pressing part 400. The glue pressing part 400 can slide and expand and contract along the front slot 104. The glue pressing part 400 is a flat structure, and the front slot 104 is also a flat structure. When the glue pressing part 400 is fully extended for glue pressing work, the middle part of the glue pressing part 400 is integrally wrapped by the front slot 104. The front slot 104 can support the glue pressing part 400, and the support surface increases the rigidity of the glue pressing part 400, enabling greater force to be used to meet the compaction operation of the fine seam caulking glue.

[0031] See Figures 5 to 7 , the glue pressing part 400 includes a glue pressing chuck 401 and a glue pressing plate 402 detachably connected to one end of the glue pressing chuck 401. The glue pressing head of the glue pressing plate 402 is located outside the glue pressing chuck 401. The glue pressing chuck 401 is slidably installed on the handle 100. A glue plate adjusting component is provided between the glue pressing chuck 401 and the handle 100. The glue pressing chuck 401 is fixed and moved by clamping or loosening through the glue plate adjusting component. In this embodiment, the glue pressing chuck 401 can adopt a metal structure to improve rigidity, and the glue pressing plate 402 adopts a rubber material with a certain flexibility to meet the glue pressing function.

[0032] The rubber plate adjusting assembly includes an adjusting slide rail 105 extending along the length direction on the handle 100. An adjusting slider 401a that slides along the adjusting slide rail 105 is installed on the rubber pressing chuck 401. An adjusting push block 401b is installed above the handle 100 where the adjusting slider 401a extends out of the adjusting slide rail 105. Positioning blocks 106 are provided on the inner surface of the adjusting slide rail 105. The positioning blocks 106 are used to position the position of the adjusting slider 401a. In this embodiment, at least two pairs of positioning blocks 106 are provided, on both side surfaces of the adjusting slide rail 105. One pair of positioning blocks 106 corresponds to the state where the rubber pressing member 400 extends completely, and one pair of positioning blocks 106 corresponds to the state where the rubber pressing member 400 retracts completely. Push the adjusting push block 401b to slide along the adjusting slide rail 105. When the adjusting slider 401a slides to the head end of the adjusting slide rail 105, the two positioning blocks 106 at the head part are stuck at the rear part of the adjusting slider 401a, so that the rubber pressing member 400 is kept in the completely extended state, and rubber pressing work can be realized; when the rubber pressing work is completed, push the adjusting slide rail 105 with reverse force. The adjusting push block 401b squeezes the two positioning blocks 106, and the adjusting push block 401b can slide reversely along the positioning blocks 106 to cross over the positioning blocks 106, driving the whole device to retract. When moving to the tail end of the adjusting slide rail 105, the two positioning blocks 106 at the tail part cooperate to keep the adjusting slider 401a in the completely retracted state, and scraping work can be realized. Here, the positioning blocks 106 play a positioning role to prevent accidental pushing out or retracting during the working process. The positioning blocks 106 can adopt arc-shaped bumps or tooth shapes.

[0033] See Figure 6 and Figure 7 , the rubber pressing chuck 401 includes a chuck body 401c. Two rubber pressing jaws 401d arranged vertically are provided at the end of the chuck body 401c. A rubber pressing slot for inserting the rubber plate 402 is formed between the two rubber pressing jaws 401d. A rubber pressing block 401e is provided at the inner bottom end of the rubber pressing slot. A rubber pressing groove 402a corresponding to the rubber pressing block 401e for clamping is provided at the tail end of the rubber plate 402. The rubber pressing block includes a connecting block and a trapezoidal chuck head provided at the outer end of the connecting block. The structure of the rubber pressing block 401e is basically the same as that of the rubber pressing groove 402a, and they cooperate with each other to realize clamping. The rubber plate 402 and the rubber pressing chuck 401 are cooperated by means of clamping and clamping, and different models can be detachably replaced.

[0034] See Figure 2 , Figure 3 and Figure 5, a caulking knife 500 is provided at the bottom of the handle 100. One end of the caulking knife 500 is provided with a caulking edge 501. The other end of the caulking knife 500 is rotatably mounted on the handle 100 through a rotating shaft 502. The rotating shaft 502 is close to the tail side of the handle 100. The caulking knife 500 can swing outwards towards the tail end around the rotating shaft 502. A stop groove 503 corresponding to the caulking knife 500 is provided on the bottom surface of the corner spatula 300. The middle part of the caulking knife 500 can abut against the stop groove 503. On the one hand, the stop groove 503 limits the caulking knife 500 to prevent it from further rotating. On the other hand, the stop groove 503 supports the caulking knife 500, facilitating forceful operation during use. The caulking knife 500 can be completely received inside the handle 100. When rotating outwards and downwards, after the caulking knife 500 swings outwards and unfolds around the rotating shaft 502 towards the outer end, at this time, the caulking knife 500 is located below the corner spatula 300, abuts against the stop groove 503, and the caulking edge 501 faces the head side of the handle 100. The caulking knife 500 can achieve the effect of a nozzle dredging needle, so it can replace the nozzle dredging needle, reducing the number of tools to be carried for the joint filling work.
