In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0034] The inventor of this solution found that in the prior art, most of the adapters that come with backpack power supplies on the market can only fix the output cable in two directions for application to specific power tools, which results in a limited range of application of power tools, lack of versatility, and inconvenience to users. The embodiment of the present invention provides the following solution:

[0035] like Figures 1 to 7As shown, an embodiment of the present invention provides a backpack power adapter, including a device body, the device body is provided with a circuit board 1 and a cable 2 for powering an electric tool, a movable rotating body 3 is provided in the device body, and the rotating body 3 is provided with a wire passage. One end of the cable 2 passes through the wire passage and is electrically connected to the circuit board 1, and the other end of the cable 2 extends out of the device body, and multiple directions of the device body are provided with receiving slots 4 for receiving and clamping the cable.

[0036] It should be noted that the cable 2 is rotated in different directions in the device body through the rotating body 3, so that the receiving slots 4 in different directions can be selected for placement and clamping according to the use requirements of different power tools. The receiving slot 4 and the cable 2 are interference fit, so that the cable 2 is placed and clamped in the receiving slot 4. After clamping, the power interface 21 of the cable 2 is used to insert the power interface on the power tool.

[0037] In some embodiments, the rotating body 3 includes a first hemispherical shell 31, a second hemispherical shell 32 and an arc-shaped slide plate 33, wherein the first hemispherical shell 31 is connected to the second hemispherical shell 32. The first hemispherical shell 31 and the second hemispherical shell 32 are both provided with an arc-shaped groove 34 corresponding to the arc-shaped slide plate 33, and the arc-shaped slide plate 33 is slidably connected in the arc-shaped groove 34. The first hemispherical shell 31 and the second hemispherical shell 32 are both provided with a cable clamping groove 35 and a first through hole 351 communicating with the cable clamping groove 35, and the arc-shaped slide plate 33 is provided with a second through hole 331. The device body includes an upper shell 5 and a lower shell 6, wherein the upper shell 5 is connected to the lower shell 6. The lower shell 6 is provided with a hollow body 61, wherein a plurality of rotation support blocks 611 are provided in the hollow body 61, and the rotation support surfaces of the rotation support blocks 611 are adapted to the first hemispherical shell 5 and the second hemispherical shell 6.

[0038] It should be noted that the upper shell 5 and the lower shell 6 are fastened and connected by four screws, and the first hemispherical shell 31 is provided with a third screw hole 37. After the first self-tapping screw 36 is screwed through the third screw hole 37, the first hemispherical shell 31 and the second hemispherical shell 32 are fastened and connected. When connected, the cable clamping grooves 35 of the first hemispherical shell 31 and the second hemispherical shell 32 are combined to form a cable clamping channel, and the first through holes 351 of the first hemispherical shell 31 and the second hemispherical shell 32 are combined to form a cable through-port. After the cable 2 enters from the cable through-port, it is clamped by the cable clamping channel, and passes through the second through hole 331 of the arc-shaped slide plate 33 to connect with the circuit board 1. Part of the cable can still be left in the first hemispherical shell 31 and the second hemispherical shell 32, so that the cable 2 will not be disconnected from the circuit board 1 due to the rotation while rotating and moving on the rotating support block 611. Since the arc-shaped slide plate 33 can slide in the arc-shaped groove 34, the cable 2 can avoid interference in the direction of rotation and movement, thereby improving the stability of rotation.

[0039] In some embodiments, the number of the rotating support blocks 611 is set to 4, and they are evenly arranged in a circular array, so that the rotating body 3 can rotate and move more stably.

[0040] In some embodiments, a sliding groove is provided on the groove wall of the arc groove 34, and sliding convex edges 332 corresponding to the sliding groove are provided on both sides of the arc slide plate 33. The sliding convex edges 332 are cooperatively connected with the sliding groove, so that the arc slide plate 33 can slide more smoothly in the arc groove 34.

[0041] In some embodiments, a pressing plate 7 and a first mounting column 71 are provided in the lower shell 6, and the pressing plate 7 is installed in the lower shell 6 through the first mounting column 71. The pressing plate 7 is provided with a hollow 72 corresponding to the hollow body 61, and the hollow 72 is a four-leaf clover structure, and a plurality of limit baffles 73 are provided around the hollow 72.

[0042] It should be noted that the hollowing 72 of the pressure plate 7 can limit the rotating body 3 from moving up and down in the hollow body 61 of the lower shell 6, and the limit baffle 73 of the pressure plate 7 can limit the rotating body 3 from moving left and right in the hollow body 61 of the lower shell 6, thereby improving the rotation accuracy of the rotating body 3.

[0043] In some embodiments, the pressing plate 7 is provided with a first boss 74 corresponding to the first mounting column 71, and the bottom of the first boss 74 is provided with a positioning groove 741 adapted to the first mounting column 71. The first mounting column 71 is provided with a first screw hole 711, and the first boss 74 is provided with a second screw hole 742 corresponding to the first screw hole 711, thereby improving the installation accuracy of the pressing plate 7.

[0044] In some embodiments, the accommodating grooves 4 are arranged at four directions of the bottom of the lower shell 6 , and the accommodating grooves 4 are perpendicular to each other in pairs, so that the cables 2 can be moved into the four accommodating grooves 4 .

[0045] In some embodiments, a disassembly slot 62 is provided at the bottom of the lower shell 6, so that it is more convenient to disassemble the entire backpack power adapter.

[0046] In some embodiments, a plurality of second mounting posts 63 are disposed in the lower housing 6 , and the circuit board 1 is mounted in the lower housing 6 via the second mounting posts 63 , wherein at least two of the second mounting posts 63 are provided with second bosses 631 .

[0047] It should be noted that the second boss 631 enables the circuit board 1 to be positioned in advance, and the second self-tapping screw 75 is screwed into the second mounting post 63 so that the circuit board 1 can be mounted with higher precision.

[0048] In some embodiments, the device body is provided with a spring 8 and a buckle 9 for mounting and positioning the electric tool, one end of the buckle 9 is connected to a moving block 91, and the lower housing 6 is provided with a moving groove 64 corresponding to the moving block. The other end of the buckle 9 is provided with a protruding block 92, the lower housing 6 is provided with a positioning column 65, one end of the spring 8 is connected to the protruding block 92, and the other end of the spring 8 is connected to the positioning column 65.

[0049] It should be noted that when the buckle 9 is pressed, the buckle moves downward along the movable groove 64 and is separated from the electric tool. When the buckle 9 is released, the buckle 9 returns to its original position due to the rebound force of the spring 8.

[0050] In specific implementation, Figures 8 to 11 As shown, the cable 2 is rotated and moved to the front, rear, left, and right cable clamping grooves 35 by the rotating body 3 according to specific needs. Figure 12 to Figure 14 As shown, the backpack power adapter can be installed in an electric wrench, a cutting machine or an electric hammer as needed, thereby expanding the scope of application and bringing more convenience to users.

[0051] To summarize, an embodiment of the present invention provides a backpack power adapter, which is provided with accommodating grooves for accommodating cables in multiple directions.
