Detailed Description of the Preferred Embodiments
[0028] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0029] Refer to Figures 1 - 4 , a trowel with an adjustable angle cutter head structure, comprising a trowel 1 and a handle 2. The trowel 1 is located at the bottom of the handle 2. An adjusting assembly is provided between the trowel 1 and the handle 2, and a disassembling assembly is provided between the trowel 1 and the handle 2;
[0030] The adjusting assembly includes a connecting rod 5. The connecting rod 5 is located between the handle 2 and the trowel 1. A knob 7 is provided on one side of the handle 2. The knob 7 is used to drive the connecting rod 5 to drive the trowel 1 for angle adjustment.
[0031] Refer to Figures 1 - 4, a cavity 6 is formed inside the handle 2. A worm 8 is rotatably connected inside the cavity 6. One end of the worm 8 penetrates through one side of the handle 2 and is fixedly connected to one side of the knob 7. The top end of the connecting rod 5 penetrates through the bottom of the handle 2 and extends into the cavity 6. A worm gear 9 is fixedly connected to the outer wall of the connecting rod 5. The worm gear 9 meshes with the worm 8. A damping bearing 10 is provided at the connection between the top end of the connecting rod 5 and the inner wall of the cavity 6. The top end of the connecting rod 5 is rotatably connected to the inner wall of the cavity 6 through the damping bearing 10.
[0032] The angle of the trowel 1 during use can be adjusted through the adjusting assembly. The specific operation method is that when the angle of the trowel 1 needs to be adjusted, first rotate the knob 7. The knob 7 drives the worm 8 to rotate in the cavity 6. Since the worm 8 meshes with the worm gear 9, the rotation of the worm 8 will drive the worm gear 9 to rotate. The worm gear 9 is fixed to the outer wall of the connecting rod 5, thereby driving the connecting rod 5 to rotate. The top end of the connecting rod 5 is rotatably connected to the inner wall of the cavity 6 through the damping bearing 10, which enables the connecting rod 5 to stably drive the trowel 1 to adjust the angle. The damping bearing 10 can provide a certain amount of resistance to keep the trowel 1 stable after being adjusted to the required angle and not easily change the angle.
[0033] Through the adjusting assembly, when dealing with an uneven base surface, the angle can be flexibly adjusted to ensure a consistent coating thickness, avoid uneven thickness, significantly improve the project quality and aesthetics, and can adapt to various complex construction environments and requirements. Whether it is large-area flat construction or construction in narrow spaces and areas with special shapes, the ideal construction effect can be achieved by adjusting the angle. Different construction workers can adjust the trowel 1 to the most suitable angle according to their own operating habits and experience, so as to construct more comfortably and efficiently and improve the construction efficiency.
[0034] Refer to Figures 1 - 3 and Figure 5 , the disassembly assembly includes an insertion plate 4. A fixing block 11 is fixedly connected to the bottom of the trowel 1. The fixing block 11 is fixedly connected to the top of the insertion plate 4. A fixing plate 3 is provided at the top of the trowel 1. A slot 12 is formed inside the fixing plate 3. The cross-sectional shapes of the slot 12 and the insertion plate 4 are both set as convex shapes. The insertion plate 4 is inserted into the slot 12. A friction pad 13 is provided on the inner wall of the slot 12. The friction pad 13 is made of an elastic material. A through hole is formed at the top of the friction pad 13. Extension plates 14 are fixedly connected to both sides of the fixing plate 3. A plurality of screws 15 are provided on the tops of the two extension plates 14. The two extension plates 14 and the trowel 1 are connected through a plurality of screws 15.
[0035] The trowel 1 and the handle 2 can be quickly installed and disassembled by means of a disassembly component. The specific operation method is as follows: during installation, first align the insertion plate 4 at the top of the trowel 1 with the slot 12 inside the fixed plate 3, and then insert the insertion plate 4 completely into the slot 12. Due to the elastic friction pad 13 on the inner wall of the slot 12, there will be a certain tightness when the insertion plate 4 is inserted, ensuring the stability of the connection. Then, pass multiple screws 15 through the extension plate 14 and tighten them to firmly connect the extension plate 14 to the trowel 1, thus completing the installation of the trowel 1 and the handle 2; when disassembling, first loosen the multiple screws 15 that fix the extension plate 14 and the trowel 1, and then pull out the insertion plate 4 connected to the fixed block 11 from the slot 12 inside the fixed plate 3, and the separation of the trowel 1 and the handle 2 can be smoothly achieved.
[0036] When the trowel 1 is worn, damaged or needs to be replaced with a different type of trowel 1, the new trowel 1 can be quickly disassembled and installed by means of the disassembly component, reducing the equipment downtime, improving the construction efficiency, reducing the maintenance and replacement costs, and the trowel 1 and the handle 2 are detachable and can be stored separately when not in use, saving storage space and facilitating storage and management.
[0037] Refer to Figures 1 - 3 , sawteeth 16 are provided on both sides of the trowel 1, and the number of sawteeth 16 is set to be multiple, and the multiple sawteeth 16 are evenly distributed along the horizontal direction of the trowel 1. The setting of the sawteeth 16 can help to form a specific texture and thickness during the scraping process, making the coating more uniform and flat.
[0038] Refer to Figure 1 , grip grooves 17 are provided on both sides of the handle 2, and the number of grip grooves 17 is set to be multiple. Through the setting of the grip grooves 17, the grip grooves 17 conform to the ergonomic design, which can make the pressure on the hand more evenly distributed, avoid excessive local force, thereby reducing the fatigue of the hand and enabling the operator to work for a longer time.
[0039] Working principle: When it is necessary to adjust the angle of the trowel 1, first rotate the knob 7, and the knob 7 drives the worm 8 to rotate in the cavity 6. Since the worm 8 meshes with the worm gear 9, the rotation of the worm 8 will drive the worm gear 9 to rotate. The worm gear 9 is fixed on the outer wall of the connecting rod 5, thereby driving the connecting rod 5 to rotate. The top end of the connecting rod 5 is rotationally connected to the inner wall of the cavity 6 through a damping bearing 10, which enables the connecting rod 5 to stably drive the trowel 1 to adjust the angle. The damping bearing 10 can provide a certain resistance to keep the trowel 1 stable after being adjusted to the required angle and not easily change the angle.
[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
