[0031] An electric chainsaw is a power tool primarily used for logging and wood processing. With societal development, the application of electric chainsaws has become increasingly widespread, placing higher demands on the operability of these products. Currently, electric chainsaws on the market lack a reference length for cutting trees, resulting in inconsistent log lengths. If the same length of wood needs to be cut, traditional electric chainsaws require measuring with a tape measure each time, which is not only cumbersome but also reduces work efficiency.
[0032] Figure 1 A schematic diagram of the structure of the housing according to an embodiment of the present invention is shown. Figure 2 for Figure 1 A structural schematic diagram of the telescopic component. (See diagram below.) Figure 1 and 2 As shown, this utility model proposes a cutting device. The cutting device of this utility model includes a housing 100, which includes a housing body 10 and a telescopic member 20. The outer side of the housing body 10 is provided with a groove. The telescopic member 20 includes a plurality of telescopic sleeves connected in sequence. The plurality of telescopic sleeves includes a first telescopic sleeve 21, which is connected to the groove. Any two adjacent telescopic sleeves are slidably connected and can be telescopically extended.
[0033] By using the cutting device in this technical solution, the outer side of the housing 100 is provided with a groove to accommodate and fix the telescopic member 20. The telescopic member 20 includes multiple telescopic sleeves and two adjacent telescopic sleeves can be slidably connected. The length of the entire telescopic member 20 can be changed by telescoping, thereby supporting the housing body 10 at a fixed height position or different height positions. This provides a reference for the height position during cutting, making it easier for the cutting device's blade to perform cutting operations of the same or different lengths on the workpiece, thus improving work efficiency and convenience. In addition, when cutting at a specific height position is not required, the telescopic member 20 can be retracted to its shortest length without interfering with the cutting operation of the cutting device.
[0034] In some embodiments of this utility model, such as Figure 1 and 3 As shown, the housing 100 also includes a sealing cover 30, which includes an annular body 31, a connecting body 32, and a sealing cover 33. The opposite ends of the connecting body 32 are connected to the annular body 31 and the sealing cover 33, respectively. The annular body 31 is installed inside the groove and spaced outside the first telescopic sleeve 21. The sealing cover 33 covers the port of the annular body 31 facing away from the bottom surface of the groove. In this embodiment, the sealing cover 30 can protect the telescopic component 20 that is fully retracted into the groove, preventing external dust and other impurities from entering the groove and affecting the subsequent use of the telescopic component 20, thus improving reliability.
[0035] Specifically, in this embodiment, such as Figure 1 and 3As shown, the annular body 31 is inserted into the groove and has a transition fit with the groove, ensuring the fixation of the overall sealing cover 30. The telescopic components 20 are spaced apart within the annular body 31, preventing the annular body 31 from affecting the expansion and contraction of the telescopic components 20, thus improving reliability. Furthermore, the connecting body 32 connects the annular body 31 and the sealing cover 33. When the sealing cover 33 separates from the groove, the connecting body 32 prevents the sealing cover 33 from being lost. The connecting body 32 is foldable, allowing the sealing cover 33 to move towards the groove and insert into the annular body 31, thus sealing both the annular body 31 and the groove. Alternatively, the sealing cover 33 can move away from the groove, separating the annular body 31 and the sealing cover 33, thus opening the inner cavity of the annular body 31 and the groove.
[0036] In some embodiments of this utility model, such as Figure 3 As shown, the capping body 33 includes a first capping portion 331 and a second capping portion 332 connected together. The first capping portion 331 can be inserted into the annular body 31, and the second capping portion 332 can abut against the side of the annular body 31 opposite to the bottom surface of the groove. In this embodiment, when the capping body 33 is engaged with the annular body 31, the first capping portion 331 is inserted into the annular body 31, ensuring a fixed fit between the capping body 33 and the annular body 31, thereby sealing the annular body 31 and the groove. The second sealing part 332 abuts against the annular body 31, which can ensure the insertion depth of the first sealing part 331, the annular body 31 and the groove, and position the insertion depth. This prevents the first sealing part 331 from being over-inserted into the annular body 31 and the groove, thus making it difficult for operators to remove the sealing body 33. It also prevents the insertion depth of the first sealing part 331, the annular body 31 and the groove from being too small, which could cause the sealing body 33 to detach due to a certain vibration.
[0037] In some embodiments of this utility model, such as Figure 3 As shown, a cavity 3311 is provided on the side of the first sealing part 331 facing the bottom surface of the groove. In this embodiment, when the telescopic member 20 is located in the groove and is not fully retracted to its shortest length, the cavity 3311 can accommodate part of the telescopic member 20, which facilitates the sealing body 33 to seal the annular body 31 and the groove, thereby improving the sealing efficiency of the sealing body 33.
[0038] In some embodiments of this utility model, the sealing cap 30 is an elastic element. In this embodiment, the elastic sealing cap 30 facilitates the insertion of the annular body 31 into the annular body 31, and also facilitates the folding or elastic deformation of the connecting body 32, ensuring that the sealing cap 33 is inserted into or separated from the annular body 31. In addition, a protrusion 3321 is provided on the side of the second sealing portion 332 away from the connecting body 32. The protrusion 3321 is also an elastic element, which facilitates the operator to pull up the sealing cap 33 located in the annular body 31 through the protrusion 3321.
[0039] Specifically, in this embodiment, the protrusion 3321 can be a semi-circular structure or a square structure. Any shape that facilitates the removal of the cap 33 located within the annular body 31 is within the protection scope of this utility model.
[0040] In some embodiments of this utility model, such as Figure 2 As shown, the multiple telescopic sleeves include a second telescopic sleeve 22, which is used to contact the ground. A fixed platform 221 is provided on the side of the second telescopic sleeve 22 facing away from the bottom surface of the groove. Along the telescopic direction of the telescopic member 20, the orthographic projection of the second telescopic sleeve 22 onto the fixed platform 221 is located within the fixed platform 221. In this embodiment, the fixed platform 221 facilitates the support of the housing 100 on the ground. Furthermore, the fact that the orthographic projection of the second telescopic sleeve 22 onto the fixed platform 221 is located within the fixed platform 221 along the telescopic direction of the telescopic member 20 results in a larger cross-section of the fixed platform 221, thereby increasing the contact area between the housing 100 and the ground. This makes it easier for the housing 100 to be supported on the ground, improving stability.
[0041] In some embodiments of this utility model, adjacent telescopic sleeves are fitted with an interference fit. In this embodiment, the interference fit ensures that sliding between adjacent telescopic sleeves is relatively effortless, and when the extended telescopic member 20 is supported on the ground, the telescopic member 20 will not retract due to the vibration of the housing 100 and the cutting device, thus improving reliability.
[0042] In some embodiments of this utility model, the depth of the groove is greater than or equal to the shortest dimension of the telescopic member 20 along its telescopic direction. In this embodiment, the above-mentioned arrangement ensures that the shortest dimension of the telescopic member 20 is completely located within the groove, ensuring that the sealing cap 30 can seal the groove without being affected, further improving reliability.
[0043] In some embodiments of this utility model, each telescopic sleeve has the same size along the telescopic direction of the telescopic member 20.
[0044] In some embodiments of this utility model, the fixed platform 221 is a rubber part. Rubber material is widely used because of its good friction properties. It can increase the friction between the shell 100 and the ground or other contact surfaces, and ensure the stability of the shell 100 when it is supported by the telescopic member 20.
[0045] In some embodiments of this utility model, the cutting device further includes a cutting tool mechanism and a driving mechanism. The cutting tool mechanism is mounted on the housing 100 and includes a blade body. The cross-section of the blade body is perpendicular to the thickness direction of the housing body 10, ensuring that the telescopic member 20 supports the housing 100 in the telescopic direction while the blade body can cut the workpiece to be cut. The driving mechanism is mounted on the housing 100 and is drivenly connected to the cutting tool mechanism.
[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
