Description

Technical Field

[0001] This utility model belongs to the field of power tool technology, specifically relating to an improved power tool working unit. Background Technology

[0002] Power tools, such as sweepers, hair dryers, and pruning machines, are commonly used equipment in daily life and work. Conventional handheld power tools generally include a handle, a linkage, and a functional section. The functional section is equipped with a working unit that is used for operation after being powered on.

[0003] Existing power tools, such as the power tool pruning machine disclosed in patent CN207269429U, have a working unit consisting of two blades that can reciprocate in a staggered manner for pruning. However, the assembly structure of the two blades is exposed, making it easy for dirt to accumulate, affecting work efficiency and making cleaning relatively troublesome. Similarly, the power tool assembly with a quick-release structure disclosed in patent CN214446112U also has a two-blade reciprocating working component, with the assembly structure exposed, making it prone to dirt accumulation and requiring improvement.

[0004] Therefore, based on some shortcomings in the existing technology, this application has made further improvements. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an improved power tool working unit with a redesigned assembly structure that is less prone to accumulating dirt and improves work efficiency.

[0006] The present invention is solved by the following technical solution.

[0007] An improved power tool working unit includes a working unit body, which includes a housing with an inner cavity and one open side, and a first working part and a second working part that can reciprocate; the assembly structure of the first working part and the second working part is disposed in the inner cavity of the housing; a sealing plate is provided on the open side of the housing, and the sealing plate, after assembly, hides the assembly structure of the first working part and the second working part in the inner cavity.

[0008] In this application, the assembly structure of the first and second working parts is concealed within an inner cavity by a sealing plate. During operation, the first and second working parts reciprocate at high frequency under the drive of the internal drive structure to prune branches. Therefore, excessive accumulation of dirt can affect work efficiency. The concealed assembly structure in this application significantly reduces dirt accumulation at the assembly structure during operation, thereby improving work efficiency.

[0009] In a preferred embodiment, the sealing plate is detachably mounted on the housing by bolts, which is convenient for assembly and disassembly and secure after assembly.

[0010] In a preferred embodiment, the first and second working pieces are branch pruning boards with a multi-blade structure, used to perform pruning operations.

[0011] In a preferred embodiment, an extension piece extends from the sealing plate and is positioned below the blade portion of the first working piece to provide a certain degree of support.

[0012] Compared with the prior art, the present invention has the following beneficial effects: it provides an improved power tool working unit, redesigns the assembly structure, and hides the assembly structure of the first and second working parts in the inner cavity, so that it is not easy to accumulate dirt during operation and improves work efficiency.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In the following embodiments, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this utility model, it should be understood that the terms such as center, longitudinal, transverse, length, width, thickness, upper, lower, front, back, left, right, vertical, horizontal, top, bottom, inner, outer, clockwise, and counterclockwise, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] See Figures 1 to 4 This utility model relates to an improved power tool working unit, which includes a working unit body. The working unit body includes a housing 1 with an inner cavity and one open side, and a first working part 2 and a second working part 3 that can reciprocate. The assembly structure of the first working part 2 and the second working part 3 is located in the inner cavity of the housing 1. A sealing plate 4 is provided on the open side of the housing 1. After the sealing plate 4 is assembled, it hides the assembly structure of the first working part 2 and the second working part 3 in the inner cavity.

[0021] Specifically, as shown in the accompanying drawings, the sealing plate 4 described in this application is detachably assembled to the housing 1 using bolts 41, making assembly and disassembly convenient and ensuring a secure fit after assembly. Furthermore, the working unit is equipped with a drive component 5. After the working unit is mounted on a power tool, the drive component 5 is connected to the output end of the motor. When the drive component 5 rotates, it drives the first working piece 2 and the second working piece 3 to reciprocate relative to each other, performing the pruning operation. The specific transmission structure is prior art and will not be described further in this application; however, reference can be made to the structures in patents CN207269429U and CN214446112U.

[0022] In the embodiments of this application, the working unit is a pruning unit, the first working piece 2 and the second working piece 3 are branch pruning boards with a multi-blade structure, used to perform pruning operations, and the sealing plate 4 has an extension piece 42 extending out, the extension piece 42 is placed below the blade part of the first working piece 2, providing a certain support capacity.

[0023] As can be seen from the above description, the working unit in this application conceals the assembly structure of the first working piece 2 and the second working piece 3 within the inner cavity through the sealing plate 4. In the working state, the first working piece 2 and the second working piece 3 move relative to each other at a high frequency under the drive of the internal driving structure to achieve the purpose of pruning branches. Therefore, excessive accumulation of dirt can affect work efficiency. The concealed assembly structure in this application can significantly reduce the accumulation of dirt at the assembly structure during operation, thereby improving work efficiency.

[0024] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
