[0024] The technical scheme of the application forms the moving space with an open lower end at the lower end of each side of the support and the pulling block 8 inserted into the moving space at one end, the lower end of the pulling block 8 being directly connected with the earphone or connected with the earphone through other connecting members, the position of the earphone or other head-mounted device being adjusted by adjusting the position of the pulling block 8 in the moving space during use, the upper end of the pulling block 8 moving in the moving space during adjustment, the pulley 5 abutting against the side wall of the moving space, the pulley 5 and the side wall having friction therebetween, a certain hand feeling being formed due to the existence of the friction, the pulley 5 rolling during the movement of the pulling block 8, the pulley 5 and the side wall being in rolling friction, the sliding friction being replaced by the rolling friction, and the friction coefficient being reduced.

[0025] Preferably, a spacer 6 is arranged between the pulley 5 and at least one side wall of the moving space, or a wear-resistant layer is arranged on the surface of the at least one side wall.

[0026] The head-mounted support is generally made of plastic at present, and the wear resistance of the plastic is poor; the friction between the pulley 5 and the side wall can also cause the wear of the side wall during long-term use, and the wear resistance of the side wall needs to be improved or other wear-resistant materials need to be used to contact the pulley 5 in order to prolong the service life; the pulley 5 abuts against the side walls on both sides during the movement of the pulling block 8, and the spacer 6 is arranged between the pulley 5 and the corresponding two side walls in the embodiment for the convenience of use; of course, the spacer 6 can also be arranged between the pulley 5 and one of the side walls, and the spacer 6 can be made of wear-resistant materials, such as wear-resistant rubber sheets and the like. The spacer 6 can be replaced when the wear-resistant rubber sheet is seriously worn. Of course, wear-resistant paint or wear-resistant plating can also be sprayed or plated on the corresponding side wall, so that a wear-resistant layer is formed on the side wall, and the wear resistance of the side wall can be effectively improved.

[0027] Further, the spacer 6 is made of Teflon EVA material.

[0028] The Teflon EVA material has the characteristics of wear resistance and softness, and can provide better friction for the pulley 5 during use, so that the pulley 5 has a certain resistance when sliding; the pulling structure has a better hand feeling when being pulled, and the spacer 6 has the characteristics of long service life due to the good wear resistance.

[0029] Further, the support comprises an upper shell 1 arranged in an arc shape, and two lower covers 7 are detachably connected to the lower ends of the two sides of the upper shell 1, and the moving space is formed between the lower end of the upper shell 1 and the corresponding lower cover 7.

[0030] As shown in Figure 1 , Figure 2 , Figure 3 In this embodiment, the lower cover 7 is connected to the inner side of the lower end of the upper shell 1, and it is understood that the lower cover 7 can also be connected to the outer side of the lower end of the upper shell 1 as an alternative structure. The lower end of the upper shell 1 and the corresponding lower cover 7 form the moving space; through the detachable connection of the lower cover 7, the pull-out block 8 can be conveniently disassembled for maintenance.

[0031] As shown in Figure 2 , Figure 3 The inner side of the lower end of the upper shell 1 is provided with two ribs 2, and the sliding groove 14 matched with the pull-out block 8 is formed between the two ribs 2.

[0032] In use, the pull-out block 8 moves relative to the upper shell 1, and the pull-out block 8 may shake during movement, thereby affecting the use experience. In order to make the movement of the pull-out block 8 directional and stable, for example, as shown in Figure 2 Two ribs 2 are designed in this embodiment, and the sliding groove 14 is formed between the two ribs 2. In use, the side surface of the pull-out block 8 abuts against or is adjacent to (the distance is less than 1mm) the side surface of the rib 2; the pull-out block 8 is limited in the sliding groove 14 during movement, and the sliding groove 14 is equivalent to a guide groove to guide the movement of the pull-out block 8.

[0033] Referring to Figure 3 , the upper end of the rib 2 extends inwardly to form a limiting block 15.

[0034] The limiting block 15 is arranged to limit the movement of the pull-out block 8.

[0035] Further, the lower end of the upper shell 1 is connected to a limiting ring 4, the middle part of the limiting ring 4 is formed with a through hole matched with the pull-out block 8, the lower end of the pull-out block 8 passes through the limiting ring 4, the limiting ring 4 is connected to the lower end of the rib 2, and when the lower cover 7 is connected to the upper shell 1, the limiting ring 4 is clamped between the lower cover 7 and the upper shell 1.

[0036] Preferably, the lower end of the rib 2 is provided with a clamping groove 13, the side of the limiting ring 4 close to the upper shell 1 is provided with a clamping block 3 matched with the clamping groove 13, the clamping block 3 extends into the clamping groove 13; the side of the limiting ring 4 away from the upper shell 1 extends outwardly to form a clamping protrusion 12, and the lower cover 7 is provided with a clamping hole 10 matched with the clamping protrusion 12, and the clamping protrusion 12 is located in the clamping hole 10.

[0037] In order to avoid the pull-out block 8 from moving out of the moving space, the limiting ring 4 is connected to the lower end of the upper shell 1, and the limiting ring 4 limits the pull-out block 8 or the pulley 5, and when limiting the pull-out block 8, the pull-out block 8 can be set as a T-shaped structure, and the lower end of the pull-out block 8 passes through the limiting ring 4, and the upper end of the pull-out block 8 is limited. Secondly, in order to fix the limiting ring 4, the limiting ring 4 is limited in the lower cover 7 by setting the clamping convex 12 and the clamping hole 10, so as to fix the limiting ring 4.

[0038] Referring to Figure 2 、 Figure 3 Figure 2 Figure 3 The upper end of the pull-out block 8 is provided with a mounting hole, a connecting shaft is connected in the mounting hole, and one or two pulleys 5 are connected through the connecting shaft, and the diameter of the pulley 5 is greater than the width of the pull-out block 8.

[0039] The diameter of the pulley 5 is set to be greater than the width of the pull-out block 8, so that the end surface of the pulley 5 protrudes from the end surface of the pull-out block 8, thereby facilitating abutting against the spacer 6.

[0040] Further, the lower cover 7 or / and the lower end of the upper shell is provided with a mounting groove 11 for mounting the spacer 6.

[0041] By setting the mounting groove 11, the spacer 6 can be conveniently mounted, and the pull-out block 8 can be prevented from moving and driving the spacer 6 to move. The mounting groove 11 of the upper shell partially overlaps with the sliding groove 14.

[0042] Further, the upper end of the lower cover 7 is provided with a positioning recess 9 matched with the pulley 5.

[0043] When not in use, in order to avoid the pull-out block 8 from moving under accidental external force, thereby causing the pulley 5 and the spacer 6 to be abraded, such abrasion is non-use state abrasion, which should be avoided. Therefore, the positioning recess 9 is arranged at the upper end of the lower cover 7, and when not in use, the pull-out block 8 is pushed upward, and the pulley 5 is clamped into the positioning recess 9.

[0044] A headset comprises the headset support.
