Description

Technical Field

[0001] This utility model relates to the field of trowels, and more particularly to an adjustable trowel. Background Technology

[0002] Plastering boards, as a common building decoration tool, are mainly used for applying plaster and smoothing walls, efficiently completing tasks such as wall plastering, leveling, and detail finishing. However, traditional plastering boards typically consist of a fixed handle and a plastering trowel, with a fixed structure and non-adjustable handle height. This design limits the flexibility of use in specific construction environments, especially in special situations requiring different height adjustments, where traditional plastering boards struggle to meet the needs, affecting construction efficiency and quality. Therefore, this utility model proposes an adjustable plastering board to solve the problem of non-adjustable handle height in existing technologies, improving the applicability and ease of operation of plastering boards under different construction conditions. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable trowel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adjustable trowel consists of a handle, a trowel, and a bracket. The handle is formed by fixing a left handle and a right handle together with a fixing bolt. The handle includes a gripping part in the middle and inclined parts at both ends. The inclined parts at both ends away from the gripping part and the two ends of the gripping part have slots. The bracket has four brackets. The upper end of the bracket has an opening, and the lower end has a lower opening. A fixing shaft is fixed between the left and right sides of the lower opening. A threaded hole is provided below the fixing shaft.

[0006] The trowel is located below the handle, and four support shafts are fixedly connected to its upper end in sequence at the front and back positions. The upper end of each support shaft is provided with an external thread, and the external threads at the upper ends of the four support shafts are threadedly connected to the threaded holes below the fixed shafts at the lower openings of the four brackets.

[0007] The four supports pass vertically through the four slots on the handle, and the width of the four supports matches the width of the four slots.

[0008] The left handle has four slots with bolt holes, and the right handle has a nut groove corresponding to the bolt holes of the left handle. A nut is placed in the nut groove, and a washer is placed outside the nut groove. The diameter of the washer is larger than the upper opening of the bracket.

[0009] The four brackets are fixed to the four slots by bolts, nuts and washers. The fixing method is that the bolts pass through the bolt holes, the upper opening of the brackets and the washers in sequence, so as to connect with the nuts in the nut slots and thus fix the brackets.

[0010] The grip portion of the handle is cylindrical and has anti-slip grooves on the side.

[0011] The upper end of the bracket is arc-shaped.

[0012] The beneficial effects of this utility model are:

[0013] By designing an adjustable bracket and handle connection structure, the height of the trowel handle can be flexibly adjusted according to construction needs. This feature is particularly suitable for scenarios where the working height needs to be frequently adjusted for different heights or different construction heights, greatly improving construction efficiency and ease of operation.

[0014] The bracket is fixed to the trowel support shaft by a threaded connection. At the same time, the bracket is also firmly installed in the groove of the handle by a combination of bolts, nuts and washers. This multiple fixing method ensures the stability and durability of the entire trowel structure, thereby guaranteeing construction quality and work safety.

[0015] Adjusting the handle height is as simple as loosening the bolts, adjusting the bracket position, and then tightening them again – a quick and easy process. Furthermore, the design of the components facilitates disassembly and assembly, making routine maintenance and replacement of damaged parts easier.

[0016] The handle's grip area is cylindrical and features anti-slip grooves, which not only conforms to ergonomic principles and reduces fatigue caused by prolonged use, but also increases stability and safety when gripping, enhancing the user's operating experience and comfort.

[0017] In summary, the adjustable trowel of this invention, through innovative design, effectively solves the problem of the non-adjustable handle height of traditional trowels. It not only improves construction efficiency and flexibility, but also enhances comfort and safety through structural optimization, demonstrating significant technological progress and practical value.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] An adjustable trowel consists of a handle 1, a trowel 2, and a bracket 3. The handle 1 is formed by a left handle 4 and a right handle 5 fixed together by a fixing bolt 6. The handle 1 includes a middle gripping part 7 and two inclined parts 8 at both ends. The inclined parts 8 at both ends away from the gripping part 7 and the two ends of the gripping part 7 have slots 9 through them. The bracket 3 has four brackets. The upper end of the bracket 3 has an upper opening 10, and the lower end has a lower opening 11. A fixing shaft 12 is fixed between the left and right sides of the lower opening 11. The fixing shaft 12 has a threaded hole below it.

[0024] The trowel 2 is located below the handle 1, and four support shafts 13 are fixedly connected to the upper end in sequence at the front and back positions. The upper end of the support shaft 13 is provided with external threads, wherein the external threads at the upper end of the four support shafts 13 are threadedly connected to the threaded holes below the fixed shaft 12 at the lower opening of the four brackets 3.

[0025] The four supports 3 pass vertically through the four slots 9 on the handle 1, and the width of the four supports 3 matches the width of the four slots 9.
