In addition, the integrated weed cutter occupies a large volume and requires a large space for storage, resulting in inconvenience in storage. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] The utility model provides a split-type power device, comprising: a carrier, a rotating device 1 detachably arranged on the carrier, a direction conversion component 3 detachably connected to the power output shaft of the rotating device 1 and capable of changing the transmission direction of the rotating device 1, a transmission shaft 10 rotatably arranged on the carrier and having one end corresponding to the direction conversion component 3, the other end of the transmission shaft 10 is also detachably connected to an external functional part, and also includes: a clutch 4 arranged between the direction conversion component 3 and the transmission shaft 10 and having two ends respectively connected to the direction conversion component 3 and the transmission shaft 10, which can connect the direction conversion component 3 and the transmission shaft 10 together so that the direction conversion component 3 drives the transmission shaft 10 to rotate, or can disconnect the connection between the direction conversion component 3 and the transmission shaft 10 so that the transmission shaft 10 stops rotating.

[0022] Specifically, the rotating device 1 of the present application can be an angle grinder, a hand drill or a hand hammer, and some lithium-powered power tools with high rotation speed can also be used.

[0023] The direction conversion component 3 can be a common right-angle gearbox on the market. Specifically, a driving gear and a driven gear are arranged in the right-angle gearbox. A predetermined angle (for example, 90 degrees) is formed between the driving gear and the driven gear and they mesh with each other. The rotating device 1 is connected to the driving gear, and the driven gear is connected to the transmission shaft 10. When the driving gear rotates, the driven gear can be driven to rotate, thereby driving the transmission shaft 10 to rotate, thereby realizing the steering of the transmission direction of the rotating device 1.

[0024] Specifically, the angle grinder is provided with a power output shaft connected to the angle grinding disc, and a power output shaft extends from both sides of the direction conversion component 3. When connecting the angle grinder with the direction conversion component 3, the angle grinding disc of the angle grinder itself is first removed, and then the power output shaft of the angle grinder is connected to the power output shaft connected to the driving gear in the direction conversion component 3 through the conversion head 2. The direction conversion component 3 converts the transmission direction of the angle grinder by 90 degrees and outputs it outward.

[0025] Specifically, the clutch 4 includes: a first pressure plate 401, a second pressure plate 402 and a lever 5, wherein the first pressure plate 401 is fixedly arranged on the transmission shaft 10, and the second pressure plate 402 is arranged on the power output shaft of the direction conversion assembly 3. Specifically, a clamping portion 301 is provided on the power output shaft of the direction conversion assembly 3 along the axial outward protrusion, and a clamping groove is provided on the second pressure plate 402, and the clamping groove on the second pressure plate 402 and the clamping portion 301 are mutually clamped and can be axially slidably matched, and when the second pressure plate 402 rotates circumferentially, the power output shaft can be driven to rotate synchronously circumferentially through the clamping groove and the clamping portion 301. Specifically, the opposing surfaces of the first pressure plate 401 and the second pressure plate 402 are friction surfaces, one end of the lever 5 is hinged to the end of the second pressure plate 402 through the first hinge shaft 6, and the other end is hinged to the carrier through the second hinge shaft 7 and extends out of the carrier. When in use, when it is necessary to output the power of the rotating device 1 to the transmission shaft 10, the user only needs to turn the lever 5 to make the second pressure plate 402 move toward the first pressure plate 401 and contact the first pressure plate 401, so that the power of the rotating device 1 is transmitted to the first pressure plate 401 through the direction conversion component 3 and the second pressure plate 402, and the first pressure plate 401 drives the transmission shaft 10 to rotate, thereby driving the saw blade 8 to rotate. When it is necessary to briefly pause the mowing operation or replace the saw blade 8, the lever 5 can be turned again to make the lever 5 drive the second pressure plate 402 to move away from the first pressure plate 401, and the second pressure plate 402 is separated from the first pressure plate 401, thereby cutting off the power output of the rotating device 1.

[0026] Specifically, the transmission shaft 10 is rotatably disposed on the carrier via a bearing 9 .

[0027] Specifically, the transmission shaft 10 is a hollow structure, and the connection shaft at the upper end of the saw blade 8 can be directly inserted into the transmission shaft 10 to achieve connection.

[0028] Specifically, the carrier may be a fixed plate.

[0029] Preferably, the carrier is a box body, and a plug interface for the functional component to be inserted and connected to the transmission shaft 10 is provided on the box body at a position corresponding to the transmission shaft 10 .

[0030] Preferably, a shoulder strap can be provided on the box body for carrying operations.
