A thin wire 21 is wound around the axial surface of the lower end of the winding post 6. There are two thin wires 21. One end of the two thin wires 21 is respectively wound around the winding post 6, and the other end is respectively fixedly connected to the end surface of the wearing strap 2 extending into the interior of the accommodating block 1. When the winding post 6 rotates around the axis, the winding post 6 will wind or release the thin wire 21, so that the length of the wearing strap 2 outside the accommodating block 1 is shortened or extended, thereby controlling the length of the wearing strap 2;

[0024] like Figure 3 As shown, the driving shaft 7 is arranged in parallel with adjacent winding poles 6, a cylinder 71 is arranged at the lower end of the driving shaft 7, the upper end of the cylinder 71 is the moving end of the cylinder 71, a rotating motor 72 is fixedly arranged above the moving end of the cylinder 71, one end of the rotating shaft of the rotating motor 72 is coaxially fixedly connected with the upper part of the driving shaft 7, and a one-way gear 1 73, a one-way gear 2 74, and a one-way gear 3 75 are arranged on the shaft of the driving shaft 7 from bottom to top in sequence; the one-way gear 1 73, the one-way gear 2 74, and the one-way gear 3 75 are all coaxially connected to the driving shaft 7 through a one-way bearing, so that the one-way gear 1 73, the one-way gear 2 74, and the one-way gear 3 75 can only rotate in one direction relative to the driving shaft 7, respectively, wherein the one-way gear 1 73 and the one-way gear 3 75 have the same rotation direction relative to the driving shaft 7, and are opposite to the rotation direction of the one-way gear 2 74 relative to the driving shaft 7;

[0025] like Figure 3 As shown, the vertical moving shaft 8 is arranged adjacent to and parallel to the driving shaft 7, the lower end of the vertical moving shaft 8 is rotatably arranged on the bottom surface of the accommodating block 1, a fixed gear 2 81 is coaxially fixedly arranged on the vertical moving shaft 8, a screw portion 82 is arranged on the upper end of the fixed gear 2 81, a nut portion 83 is sleeved on the screw portion 82, the screw portion 82 and the nut portion 83 are threadedly matched, the fixed gear 2 81 drives the screw portion 82 to rotate by meshing with the one-way gear 1 73 or the one-way gear 2 74, so that the nut portion 83 descends or rises, the top end of the nut portion 83 is fixedly arranged with the bottom end of the support plate 4, the outside of the nut portion 83 is fixedly arranged with a protrusion 831, the protrusion 831 is vertically slidably arranged in a limiting guide rail 9 adjacent to and parallel to the vertical moving shaft 8, the limiting guide rail 9 is used to limit the nut portion 83 from rotating, so that the screw portion 82 and the nut portion 83 realize thread transmission;

[0026] like Figure 3As shown, the fixed gear 1 61 can mesh with the one-way gear 2 74 or the one-way gear 3 75 for transmission.

[0029] Preferably, as an implementable embodiment, a touch button or a push button (not shown) is arranged outside the receiving block 1, so that the touch button or the push button is electrically connected to the single-chip computer, and a signal is sent to the single-chip computer by pressing or touching the button, so that the single-chip computer controls the bracelet display screen 5 to be exposed or retracted inward;

[0030] Working principle: a pressure sensor (not shown) is arranged under the receiving block 1, and the operation of the cylinder 71 and the rotating motor 72 is controlled by a program set in the single-chip microcomputer. The single-chip microcomputer (not shown) is arranged inside the receiving block 1, so that when the pressure measured by the pressure sensor is less than the set minimum value, the wearing strap 2 is controlled to retract; when the pressure measured by the pressure sensor is between the set minimum value and the maximum value, the length of the wearing strap 2 is controlled to remain unchanged; when the pressure measured by the pressure sensor is greater than the maximum value, the wearing strap 2 is controlled to extend; a touch button or a push button (not shown) is arranged outside the receiving block 1, so that the touch button or the push button is electrically connected to the single-chip microcomputer, and a signal is sent to the single-chip microcomputer by pressing or touching the button, so that the single-chip microcomputer controls the bracelet display screen 5 to be exposed or retracted inward; in the general state, the fixed gear The wheel 1 61 meshes with the one-way gear 3 75, and the fixed gear 2 81 meshes with the one-way gear 2 74. Looking downward from the upper end of the rotating motor 72, the clockwise rotation of the rotating shaft of the rotating motor 72 is considered positive rotation, so that when the rotating shaft of the rotating motor 72 rotates forward, it drives the winding column 6 to rotate and wind the thin wire 21, so that the extended length of the worn watch strap 2 is reduced. When the rotating shaft of the rotating motor 72 reverses, it drives the screw portion 82 of the vertical movable shaft 8 to rotate, so that the nut portion 83 is threadedly driven, so that the support plate 4 and the bracelet display screen 5 rise; after the cylinder 71 starts to extend, the upper end of the driving shaft 7 rises, so that the fixed gear 1 61 meshes with the one-way gear 2 74, and the fixed gear 2 81 meshes with the one-way gear 1 73, so that the forward and reverse rotation of the rotating motor 72 controls the extension of the worn watch strap 2 and the descent of the bracelet display screen 5.
