[0020] The wire harness storage assembly 3 includes a mounting frame 36, and a storage seat 31 is installed on the outer side of the mounting frame 36, and at the same time, the end of the storage seat 31 is fixedly connected to the connecting column 32, and the end of the connecting column 32 away from the storage seat 31 is fixedly connected to the transmission frame 35, and the driving block 33 is installed inside the transmission frame 35, and the driving block 33 is fixedly connected to the driving ring 34, and at the same time, a connecting plate 45 is fixedly installed on the inner wall of the driving ring 34, and the end of the connecting plate 45 away from the driving ring 34 is fixedly connected to the connecting disk 42, one end of the rotating shaft of the connecting disk 42 is movably connected to the outer side wall of the welding device body 1, and the other end of the rotating shaft of the connecting disk 42 passes through the side wall of the top plate 37 through a bearing and is fixedly connected to the rotating wheel 38.

[0021] Working principle: When in use, the wire harness 2 is wound around the outside of the three groups of storage seats 31. At this time, the rotating wheel 38 is rotated, and the rotating wheel 38 drives the driving ring 34 to rotate through the connecting plate 45. The driving ring 34 drives the transmission frame 35 to move upward through the three groups of driving blocks 33 thereon, so that the three groups of storage seats 31 are extended outward. By increasing the friction between the three groups of storage seats 31 and the wire harness 2, the wire harness 2 is tightened and fixed, so as to avoid the wire harness 2 from falling off when the welding device body 1 is carried, and also to avoid the wire harness 2 from falling off and causing tripping.

[0022] As a preferred implementation, the storage seat 31 is made of plastic material and has an “L”-shaped cross-section. The storage seat 31 is arranged in three groups evenly distributed on the outside of the installation frame 36 .

[0023] like Figure 1-4 As shown: the storage seats 31 are arranged in three groups evenly distributed on the outside of the installation frame 36; the three groups of storage seats 31 move inward synchronously to reduce the friction between the three groups of installation frames 36 and the wiring harness 2, making it easier to remove the wiring harness 2.

[0024] As a preferred embodiment, the wiring harness 2 is wound around the outer side of the three groups of storage seats 31, and the three groups of storage seats 31 are synchronously driven to rise and fall through the driving ring 34, the connecting column 32 and the transmission frame 35. The three groups of sliders 41 are evenly installed on the outer side of the driving ring 34, and the three groups of sliders 41 are all slidably set inside the slide rail 40, and the slide rail 40 is set inside the installation frame 36.

[0025] The storage seats 31 are arranged in three groups evenly distributed on the outside of the mounting frame 36; the three groups of storage seats 31 move outward synchronously, increasing the friction between the three groups of mounting frames 36 and the wiring harness 2, making it easier to fix the wiring harness 2 on the outside of the welding device body 1 and prevent it from falling off.

[0026] As a preferred embodiment, an inclined force-bearing groove is opened inside the transmission frame 35 at the end of the connecting column 32, and the surface of the inclined force-bearing groove covers the downward pressure force-bearing groove. At the same time, the downward pressure force-bearing groove is arranged on the bottom surface of the driving block 33, and the driving block 33 is arranged to be evenly installed in three groups on the driving ring 34.

[0027] The surface of the inclined stress groove covers the downward stress groove, so that when the drive ring 34 rotates counterclockwise, the drive block 33 exerts force on the transmission frame 35, causing the transmission frame 35 to move upward to tighten the wire harness 2 wrapped on the three sets of storage seats 31.

[0028] As a preferred embodiment, a ratchet 43 is fixedly mounted on the rotating shaft of the connecting disk 42, and the size of the ratchet 43 is adapted to that of the ratchet 44. At the same time, the end of the ratchet 44 is clamped on the ratchet 43, and the ratchet 44 is movably arranged inside the mounting frame 36, and a spring 39 is installed on the ratchet 44.

[0029] When the connecting disk 42 is driven to rotate by the rotating wheel 38, when the connecting disk 42 and the ratchet 43 rotate counterclockwise, the ratchet 44 will not hinder the rotation of the ratchet 43; on the contrary, the setting of the ratchet 44 can prevent the ratchet 43 from rotating counterclockwise, thereby ensuring the stability of the storage seat 31 when it is stationary.

[0030] The top plate 37 is a funnel-shaped structure made of plastic material, and a rotating wheel 38 is installed on the outer side of the top plate 37. The rotating wheel 38 is rotated to drive the three groups of storage seats 31 to move outward to tighten the wiring harness 2.
