Description

Technical Field

[0001] This utility model belongs to the field of cutting machine technology, specifically relating to a cutting machine with an adjustable cutting head. Background Technology

[0002] In the construction, renovation, woodworking, and DIY industries, there is a growing demand for small, portable cutting tools. These tools need to balance cutting power, operational flexibility, and safety. Currently, the mainstream portable cutting tools on the market mainly include angle grinders, reciprocating saws, and cutting machines specifically designed for sheet metal cutting that have emerged in recent years.

[0003] To compensate for the shortcomings of angle grinders and reciprocating saws in precision cutting, rechargeable cutting machines specifically designed for high-precision cutting have emerged on the market. These machines typically employ a fixed head with a guard and base, and a built-in small motor drives a small-diameter saw blade for cutting, balancing safety and cut smoothness. However, these products also face a key bottleneck: Its head and body are fixed as one piece, resulting in a single, unremarkable design. When performing trimming or cutting work in narrow spaces such as corners, inside cabinets, or around pipes, its long body interferes with the wall, preventing in-depth work and severely limiting its flexibility. Users are forced to carry an additional angle grinder to complete the task.

[0004] In summary, there is a lack of a cutting machine in the current technology that is suitable for multiple scenarios. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a cutting machine with an adjustable cutting head.

[0006] A cutting machine with an adjustable cutting head includes a cutting head, a handle assembly, and a rotating connector. The cutting head is connected to the handle assembly via the rotating connector, which allows the cutting head to switch between a 0° position and a 90° position relative to the handle assembly. When the cutting head is at the 0° position, the axis of the cutting head coincides with or is parallel to the axis of the handle assembly, and the cutting machine is horizontal. When the cutting head is at the 90° position, the axis of the cutting head is perpendicular to the axis of the handle assembly, and the cutting machine is vertical.

[0007] Preferably, the rotary connector is installed in the corresponding grooves of the housing assembly and handle assembly of the cutting head. The rotary connector includes a cylindrical part and two annular protrusions. The two annular protrusions are respectively connected to the two ends of the cylindrical part and respectively engaged in the corresponding grooves of the housing assembly and handle assembly.

[0008] Preferably, a locking assembly is provided on the side of the rotating connector. The locking assembly includes a locking screw and a fixing nut. The fixing nut is installed inside the housing assembly of the cutting head. The locking screw is threadedly connected to the fixing nut. When the locking screw abuts against the rotating connector, the cutting head is locked. When the locking screw is separated from the rotating connector, the cutting head is unlocked.

[0009] Preferably, a snap-fit ​​groove is provided on the handle assembly at the position corresponding to the rotating connector, and a snap-fit ​​component that cooperates with the snap-fit ​​groove is provided on the housing assembly of the cutting head.

[0010] Preferably, the cutting head includes a housing assembly, a drive assembly, and an output assembly. The drive assembly is located inside the housing assembly, and the output assembly is installed at the drive end of the drive assembly. The output assembly extends out of the housing assembly and connects to the corresponding cutting accessory.

[0011] Preferably, a protective cover is provided on the cutting head at the position corresponding to the cutting accessory, and a base is installed on the protective cover by a fixing component. The base has an L-shaped support structure.

[0012] Preferably, the end of the handle assembly away from the cutting head is equipped with a pin assembly for connecting to a power source to power the entire machine.

[0013] The beneficial effects of this utility model are: the adjustable cutting head of this cutting machine, through the structural design of the rotating connector and its cooperation with the cutting head and handle assembly, can realize the rotation switching of the cutting head between the 0° position and the 90° position, realizing "one machine for multiple uses" and expanding the application scenarios of the cutting machine.

[0014] Furthermore, the rotating connector has a simple and compact structure and a mature manufacturing process. While enabling the cutting machine to perform multiple functions, it does not significantly increase the overall complexity and manufacturing cost, which is conducive to its widespread use.

[0015] Furthermore, through the internal structure design of the handle assembly and the configuration of the locking assembly, users can quickly switch and lock the cutting machine mode according to their needs, resulting in high work efficiency. Attached Figure Description

[0018] Example 1 like Figure 1 As shown, a cutting machine with an adjustable cutting head includes a protective cover 1, a base 2, a cutting head 3, a handle assembly 4, a pin assembly 5, and a rotating connector 6. One end of the handle assembly 4 is connected to the cutting head 3 via the rotating connector 6, and the other end is connected to the pin assembly 5. The pin assembly 5 is used to connect a lithium battery to provide power for the entire machine.

[0019] The rotating connector 6 allows the cutting head 3 to rotate between 0° and 90° positions relative to the main body, and is equipped with a locking component to securely lock the cutting head 3 in the user-selected position.

[0020] like Figure 6 As shown, when the cutting head 3 is in the 0° position, the axis of the cutting head 3 is basically coincident with or parallel to the axis of the handle assembly 4, and the whole is horizontal, which is suitable for conventional cutting and force-driven sawing.

[0021] like Figure 7 As shown, when the cutting head 3 is in the 90° position, the axis of the cutting head 3 is perpendicular to the axis of the handle assembly 4, and the whole is vertical, which is suitable for lateral operation in narrow spaces.

[0022] like Figure 1 As shown, the front end of the cutting head 3 is equipped with a protective cover 1 to protect the operator and prevent cutting debris from injuring the operator. The protective cover 1 is connected to the base 2 by a fastener 12, which can be a fixing bolt or other components. The base 2 is an L-shaped support structure that provides support for the cutting machine and improves the stability of the cutting machine during use.

[0023] Furthermore, such as Figure 2As shown, the cutting head 3 includes a housing assembly 9, a drive assembly 10, and an output assembly 11. The drive assembly 10 is located inside the housing assembly 9, and the drive end of the drive assembly 10 is equipped with the output assembly 11. The output assembly 11 extends out of the housing assembly 9 and connects to the cutting accessories. The cutting accessories can be cutting discs, saw blades, grinding discs, etc., and users can select them according to their needs.

[0024] like Figure 3 As shown, the rotating connector 6 is installed in the corresponding grooves of the housing assembly 9 and the handle assembly 4. Specifically, as... Figure 4 As shown, the rotating connector 6 includes a cylindrical part and two annular protrusions. The two annular protrusions are respectively connected to the two ends of the cylindrical part and respectively engaged in the grooves of the housing assembly 9 and the handle assembly 4 at corresponding positions, so as to realize the connection and rotation between the housing and the handle.

[0025] In the actual manufacturing of the rotary connector 6, a groove can be directly cut into the column structure to form a shape such as... Figure 4 The rotating connector 6 shown consists of a cylindrical part and two annular protrusions.

[0026] like Figure 3 As shown, the rotating connector 6 is equipped with a locking component, which includes a locking screw 8 and a fixing nut 7. The fixing nut 7 is installed inside the housing assembly 9. The locking screw 8 is threadedly connected to the fixing nut 7. When the locking screw 8 abuts against the rotating connector 6, the cutting head 3 is locked. When the locking screw 8 moves away from the rotating connector 6, the cutting head 3 is unlocked and can be rotated relative to the handle assembly 4.

[0027] Furthermore, such as Figure 5 As shown, in order to rotate and position the cutting head 3 to ensure that the rotation angle is 90°, a limiting groove 401 is provided on the handle assembly 4 at the position corresponding to the rotating connector 6. The corresponding housing assembly 9 is equipped with a snap-fit ​​component that works with the limiting groove 401. The rotation angle of the cutting head 3 is limited by the cooperation between the snap-fit ​​component and the limiting groove 401. After the cutting head 3 rotates 90°, it is limited to achieve accurate positioning at the 0° and 90° positions.

[0028] Working principle: This adjustable cutting head cutting machine allows users to select the appropriate cutting accessories and connect them to the drive component 11 according to their needs, and then select the corresponding workstation of the cutting head 3 according to the requirements of the scenario.

[0029] When switching workstations, the locking screw 8 is loosened by the threaded engagement between the locking screw 8 and the fixing nut 7, which separates it from the rotating connector 6 and unlocks the cutting head 3. Then, through the structural engagement between the rotating connector 6, the housing assembly 9, and the handle assembly 4, the cutting head 3 is rotated to the corresponding workstation. The locking screw 8 is then tightened to abut against the rotating connector 6, locking the cutting head 3, and then the corresponding cutting operation can begin.
