In this embodiment, the bow 621 includes a middle guide portion 621a with a vertical middle section and side fixing portions 621b extending laterally from two ends of the middle guide portion 621a, the whole is arc-shaped, and the lead frame 62 further includes a plurality of wire buckles 623 for fixing the wires 7, the wire buckles 623 are vertically arranged along the length direction of the middle guide portion 621a of the bow 621, so that the wires 7 bypassing the bow 621 can be clamped and fixed on the bow 621 by the wire buckles 623, and the length and state of the wires 7 between the lead frame 62 and the control element 52 can be kept fixed when the control panel 5 is detached or opened, so that the wires 7 pulled or extruded by the control panel 5 due to opening cannot directly act on the control element 52, and damage caused by pulling, extrusion and torsion of the wires 7 is avoided.

The cable 7 led out from the inner shield 21 accumulates a section of non-stretched portion in the form of an arc at the front end of the side guide frame 11, that is, the section is bent or curled between the inner shield 21 and the side guide frame 11, and when the control panel 5 is opened, a margin is given to a little pull of the cable 7 on the lead frame 62, so that the swinging movement of the control panel 5 is prevented from being influenced by the tension;
Moreover, in this embodiment, the lengths of the bows 621 extending from the base frame 61 and the opening portion opened by swinging the enclosure space decrease sequentially towards the hinge connection portion of the base frame 61, that is, the lengths of the bows 621 extending from the outer side of the opening portion in the opened base frame 61 decrease gradually inwards, so that the cables 7 on the bows 621 on the outermost layer are pressed onto the cables 7 on the next layer, and stacking interference of the cables 7 between the bows 621 when the bows 621 are on the same plane is avoided;
Therefore, the fixing seat 622 is installed at two ends of the bow frame 621 through the adjusting seat 624, the adjusting seat 624 is movably installed on the side fixing portions 621b at two ends of the bow frame 621, the adjusting seat 624 and the bow frame 621 between the fixing seats 622 with two sides clamped in the limiting grooves 61a are clamped and fixed, the inner side of the adjusting seat 624 is provided with a sliding groove along the length direction of the adjusting seat 624, the side fixing portions 621b are clamped in the sliding, and one surface of the side fixing portions 621b close to the bottom of the sliding groove and the bottom surface of the sliding groove are provided with a structure or a coating for limiting the mutually attached two from sliding, so that when the adjusting seat 624 at two sides extrudes towards the center to drive the side fixing portions 621b to clamp on the base frame 61, the adjusting seat 624 and the side fixing portions 621b cannot slide relatively, in general, in the basic setting, the adjusting seat 624 can adopt a tubular structure with the sliding groove, and the tubular structure is generally required to be in clearance fit with the side fixing portions 621b, but the coating on the surface of the side fixing portions 621b can make the side fixing portions 621b troublesome when the adjusting seat is pulled in the adjusting seat, and the clearance between the two portions is not stable even if the two are too large;
Therefore, in this embodiment, the sliding groove is provided with an opening on the side of the adjusting seat 624, and the opening direction is directed to the adjusting seat 624 provided on the other side, the end of the side of the adjusting seat 624, which is close to one side of the bow frame 621, is provided with the clamping beam 625, the clamping beam 625 extends from the adjusting seat 624 towards the middle guide portion 621a, the shortest distance from the clamping beam 625 to the bottom edge of the sliding groove of the adjusting seat 624 is greater than or equal to the vertical thickness of the side fixing portion 621b, so that when the clamping beam 625 needs to adjust the position on the adjusting seat 624, the adjusting seat 624 swings to enable the adjusting seat 624 and the side fixing portion 621b to be staggered, after the adjusting seat 624 is moved to the required position, the adjusting seat 624 is broken back to be attached to the side fixing portion 621b, then the bow frame 621 is bent to enable the fixing seat 622 to be mounted on the base frame 61, the adjusting seat 624 drives the side fixing portion 621b to be pressed down, and the clamping beam 625 is pressed against the side fixing portion 621b upwards, thereby stabilizing the side fixing portion 621b up and down, and the risk of shaking is avoided on an adjustable basis.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
