They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0024] refer to Figures 1 to 4 , an electrical instrument with a wire harness storage structure, comprising an instrument body 1 and a display screen 2 and an operation button 3 embedded in the front surface of the instrument body 1, a storage box is provided inside the instrument body 1, and a limit box 6 is provided at the lower end of the instrument body 1, the storage box comprises a reel 9, a baffle 10 is provided on the reel 9, and a rotating drum 11 is provided at one end of the reel 9, a wire harness 5 is wound on the reel 9, an insertion tube 12 is provided at one end of the rotating drum 11, and an adjustment ring 8 is connected to one end of the insertion tube 12 near the outside of the instrument body 1, a pressing strip 4 is embedded in the front and back surfaces of the limit box 6, and a threading hole 17 is provided inside the limit box 6, and a wire harness fixing structure is relatively provided inside the threading hole 17.

[0025] The storage box includes a reel 9, a baffle 10 is provided on the reel 9, and a rotating drum 11 is provided at one end of the reel 9, a wire harness 5 is wound on the reel 9, and an insert 12 is provided at one end of the rotating drum 11. The rotating drum 11 is a hollow multi-corrugated structure. The outer diameter of the insert 12 is the same as the inner diameter of the rotating drum 11, and the outer edges of the insert 12 are the same as the number of the inner edges of the rotating drum 11. One end of the insert 12 is connected to the outside of the instrument body 1 with an adjusting ring 8, and the outer wall of the instrument body 1 is close to the adjusting ring 8. A plurality of limiting holes 7 are provided at the inner side thereof, and two limiting strips 13 are provided on the inner side of the adjusting ring 8. The diameter of the limiting hole 7 is the same as that of the limiting strip 13. When the adjusting ring 8 is pulled, the limiting strip 13 is disengaged from the limiting hole 7. Then the insert cylinder 12 is rotated, and the insert cylinder 12 drives the rotating drum 11 to rotate, which can drive the reel 9 to rotate, and the wire harness of the reel 9 can be wound up. After winding up, press the adjusting ring 8, and the limiting strip 13 is inserted into the limiting hole 7 and fixed.

[0026] The front and rear surfaces of the limit box 6 are embedded with a pressing strip 4, and the interior of the limit box 6 is provided with a threading hole 17, and the interior of the threading hole 17 is provided with a relatively arranged harness fixing structure, the harness fixing structure includes a limit strip 14, a connecting rod 16 and an arc ring 18, the limit strip 14 is installed on the rear side of the pressing strip 4, and one end of the limit strip 14 is connected to the connecting rod 16, a spring 15 is provided between the limit strip 14 and the outer wall of the limit box 6, one end of the connecting rod 16 is connected to the arc ring 18, and a protective strip 19 is provided on the inner side of the arc ring 18. The two harness fixing structures are arranged relatively, and the harness 5 passes through When the spring 15 is between the two arc-shaped circles 18, the protective strip 19 is a component made of rubber. The protective strip 19 serves to increase friction and provide protection. The protective strip 19 is a long arc-shaped structure fixed on the inner side of the arc-shaped circle 18. When the wiring harness passes through the two arc-shaped circles 18, the wiring harness squeezes the two arc-shaped circles 18 outward. At this time, the spring 15 is in a compressed state, and the wiring harness is tightly fixed by the two arc-shaped circles 18, playing a fixing role. When the pressing strip 4 is squeezed inward, the two arc-shaped circles 18 move outward, and the squeezing force applied to the wiring harness becomes smaller, so the wiring harness can be pulled.

[0027] During use, after the electrical instrument is fixed, if the wiring harness is too long, first pull the adjusting ring 8 outward, then squeeze the pressing strip 4 inward, lengthen the distance between the two arc circles 18, and loosen the wiring harness. Then rotate the adjusting ring 8. At this time, the insert cylinder 12 drives the rotating drum 11 to rotate, which can drive the reel 9 to rotate, and the wiring harness can be wound around the reel 9. After adjustment, press the adjusting ring 8, insert the limiting insert strip 13 on the adjusting ring 8 into the limiting hole 7, and then release the pressing strip 4 to fix the wiring harness. It is not only beautiful, but also convenient for maintenance operations by the staff.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
