[0034] See Figure 1-6 This utility model provides a flexible elastic element 1 for use in a track socket adapter. The track socket adapter includes a base 2, and an active rotating element 3, an N-pole conductive sheet 4, and an L-pole conductive sheet 5 disposed on the base 2. The active rotating element 3 is provided with a rotating protrusion 31.

[0035] The flexible elastic element 1 is provided with three limiting points to divide the flexible elastic element into four sections;

[0036] The flexible elastic element 1 achieves the storage or unfolding state of the N-polar conductive sheet 4 and the L-polar conductive sheet 5 by abutting and cooperating with the rotating protrusion 31 through its three limiting points.

[0037] In this embodiment, the flexible elastic element 1 includes a fixed end 11, which is fixedly disposed on the base 2. The base 2 is provided with a fixing groove 21, in which the fixed end 11 can be fixed. The fixed end 11 is L-shaped, and the fixing groove 21 is L-shaped. The flexible elastic element 1 also has a free end 12, which is located on the base 2. In this embodiment, the flexible elastic element 1 is an irregularly shaped retaining spring, and the base 2 is also provided with an L-shaped fixing groove 21. The fixed end of the irregularly shaped retaining spring is L-shaped and fixed in the fixing groove. It should be noted that the shape of the flexible elastic element and the shape of the fixing groove in this embodiment can also be other than these, and the present invention is not limited thereto.

[0038] In this embodiment, the three limiting points of the flexible elastic element are the first limiting point P1, the second limiting point P2 and the third limiting point P3. The second limiting point P2 is located between the first limiting point P1 and the third limiting point P3, and the first limiting point P1 is close to the fixed end 11.

[0039] When the rotating protrusion 31 abuts against the first limiting point P1, the N-polar conductive sheet 4 and the L-polar conductive sheet 5 rotate to the first angular position. The first angular position corresponds to the retracted state of the N-polar conductive sheet 4 and the L-polar conductive sheet 5, that is, the N-polar conductive sheet 4 and the L-polar conductive sheet 5 are in the retracted state, and the track socket is in the de-energized state. As the rotating outer shell is rotated clockwise, the rotating protrusion 31 slides along one side of the flexible elastic element 1 to the second limiting point P2. The rotating protrusion 31 experiences the greatest resistance at the second limiting point P2.

[0040] When the outer shell continues to rotate clockwise, the rotating protrusion 31 slides from the second limiting point P2 to the third limiting point P3. The active rotating component 3 drives the conductive rotating body to rotate, which in turn drives the N-pole conductive sheet 4 and the L-pole conductive sheet 5 to rotate to the second angle position. The second angle position corresponds to the unfolded state of the N-pole conductive sheet 4 and the L-pole conductive sheet 5, that is, the N-pole conductive sheet 4 and the L-pole conductive sheet 5 are in the unfolded state, and the track socket is in the power-taking state.

[0041] Furthermore, when rotating the outer casing to rotate the N-polar conductive sheet 4 and the L-polar conductive sheet 5 from the unfolded state to the retracted state, the above operation can be reversed, which will not be elaborated here.

[0042] In this embodiment, the base 2 is also provided with a limiting spring 6. The flexible elastic element 1 can be abutted against the base 2 by the limiting spring 6. When the rotating protrusion 31 slides along one side of the flexible elastic element 1, the limiting spring 6 is used to provide resistance.

[0043] See Figure 6In this embodiment, the flexible elastic element is plate-shaped, and its free end 12 can be straight or L-shaped. This flexible elastic element has the advantage of providing the required elastic force within a limited space, making it suitable for compact designs. The three limiting points correspond to different working states or physical constraints, which are used to control the movement rhythm and positional stability of the conductive sheet. The four segments have different stiffness or elasticity characteristics. In this embodiment, the segmented elasticity + limiting point setting makes the movement of the conductive sheet more controllable and avoids overpressure or misalignment.

[0044] The flexible elastic element provided in this embodiment is equipped with different limiting points and sections, so that the product has a jerky feeling and a push-pull feeling when rotating. When the product is between the initial and energized positions, it protrudes on the inclined surface of the flexible elastic element, so that there is a feeling of being blocked when the product rotates. When the hand is released at this position, the protrusion will automatically return to the initial position. When the product is in the unlocked position, it protrudes on the small inclined surface of the flexible elastic element, so that there is a feeling of being blocked when the product rotates. When the hand is released at this position, the protrusion will automatically return to the initial position.

[0045] The flexible elastic element provided by this utility model realizes automatic control of the unfolding and retracting state of the conductive sheet in the track socket. It is set as a spring-type structure with three limiting points and divided into four sections. The first section from right to left plays a fixing role, the second section plays an accelerating and pushing role, the third section plays a positioning role, and the fourth section plays an accelerating and pushing role. The flexible elastic element provided by this utility model realizes convenient cooperation with the rotating protrusion of the active rotating part. This utility model realizes automatic control of the unfolding and retracting state of the conductive sheet in the track socket by introducing an irregularly shaped snap ring structure with multiple limiting points.

[0046] The limiting points in this invention control the angle and position of the conductive sheet by contacting the protrusions on the rotating component. Multiple limiting points enable precise positioning of the conductive sheet in different states. The irregularly shaped retaining spring is integrated into the base, maximizing space utilization. Switching between the limiting points provides clear tactile feedback, enhancing the user experience. Furthermore, the conductive sheet can only be unfolded / retracted when the outer shell is actively rotated, preventing accidental activation or deactivation.
