[0029] Reference Figure 1-8 The image shown is a preferred embodiment of the present invention.

[0030] The paddle-type hand strap bracket includes an adjustment rail component 1, a hand strap component 2, a slider 3, and a paddle component 4. The adjustment rail component 1 is assembled or integrally formed with the protective shell. The slider 3 is docked with the hand strap component 2 and is movably assembled with the adjustment rail component 1. The slider 3 is driven to move relative to the adjustment rail component 1. The movement of the slider 3 causes the hand strap component 2 to bend or unfold. The adjustment rail component 1 has multiple adjustment holes 11, which are arranged at intervals along a straight line. The paddle component 4 is installed on the slider 3 and is embedded in one of its adjustment holes 11. The paddle component 4 is driven to switch between different adjustment holes 11.

[0031] In the aforementioned paddle-type wristband bracket, when the user switches the state of the wristband 2, the user applies a pushing force to the slider 3, causing the slider 3 to move relative to the adjusting rail 1. The movement of the slider 3 drives the paddle 4 to move, thereby allowing the paddle 4 to switch between different adjustment holes 11, so that the wristband 2 is in a bent support state or an unfolded storage state. In this way, based on the user's pushing force, the paddle 4 moves relative to the adjusting rail 1. At this time, the adjustment hole 11 applies resistance to the paddle 4 in the opposite direction and produces a sound, which improves the tactile feel of the slider 3, improves the user's pushing feel of the slider 3, and thus improves the user's control over the switching of the state of the wristband 2, as well as the user's operating experience with the wristband bracket.

[0032] The paddle component 4 includes a paddle post 41 and a paddle block 42. The upper part of the paddle post 41 is arranged to be connected to the slider, and the lower part of the paddle post 41 is arranged to be connected to or integrally formed with the paddle block 42. The paddle post 41 extends vertically in the direction away from the slider 3, and the paddle block 42 is used to be embedded in the adjustment hole 11.

[0033] In this way, the position of the hand strap 2 is achieved by the cooperation of the paddle block 42 and the adjustment hole 11, ensuring the support of the protective shell. Under the action of the paddle post 41, the paddle block 42 has swing space, which facilitates the cooperation of the paddle block 42 and each adjustment hole 11.

[0034] The slider 3 has a block groove with a groove wall. The lever post 41 includes a bent section and a lever post section. The two ends of the bent section are respectively connected to the upper part of the lever post section and the groove wall. The lever post section is located in the block groove and is suspended. The lower part of the lever post section is connected to the lever block 42 or integrally formed.

[0035] Thus, under the action of the block groove, when the user applies a pushing force to the slider 3, the slider 3 drives the paddle 4 to move, while the adjustment hole 11 applies resistance to the paddle 4 in the opposite direction, causing both the paddle post 41 and the paddle block 42 to swing until the pushing force overcomes the resistance, at which point the paddle block 42 switches to the next adjustment hole 11.

[0036] The paddle block 42 has a paddle surface. Along the direction away from the paddle post 41, the paddle surface is arranged in an arched arc shape, and the paddle surface is arranged in a flat contact with the adjustment hole 11. In this way, because the paddle surface is arranged in an arched arc shape, the stability is stronger, and it is easier to pre-set the cooperation between the paddle block 42 and the adjustment hole 11.

[0037] The paddle post 41 is elastically arranged, which facilitates the swinging of the paddle post 41 and the switching of the paddle block 42 along different adjustment holes 11.

[0038] The adjustment holes 11 are arranged in a hemispherical shape along the direction away from the slider 3; this facilitates the entry or exit of the paddle block 42, thereby facilitating the switching of the paddle block 42 between the various adjustment holes 11.

[0039] Alternatively, the adjustment holes 11 are arranged in a wave-like pattern to facilitate the entry or exit of the paddle block 42, thereby facilitating the switching of the paddle block 42 along the adjustment holes 11.

[0040] The hand strap 2 includes a first strap plate and a second strap plate, which are arranged in a movable docking configuration. The slider 3 is docked with either the first or second strap plate. Thus, by moving the slider 3, the first and second strap plates are arranged in an unfolded and bent configuration, thereby achieving the switching between different states.

[0041] A protective case can be a phone case or a tablet case. Example

[0042] The rail adjustment component 1 has a rail bottom surface, which is arranged in an elongated shape. Various adjustment holes 11 are formed on the rail bottom surface. The slider 3 has a bottom block surface facing the rail adjustment component 1. The paddle block 42 extends to the outside of the bottom block surface and is embedded in one of the adjustment holes 11.

[0043] In this way, along the direction away from the protective shell, the paddle block 42 is aligned with and embedded in the adjustment hole 11, which improves the smoothness of the slider 3's movement.

[0044] The paddle block 42 is positioned in the middle of the bottom block surface, which makes the force on the paddle block 42 more even and reduces the risk of shaking when the slider 3 moves.

[0045] The rail adjustment component 1 includes two side rail plates, which are arranged at intervals. The bottom surface of the rail is located between the two side rail plates, and along the width direction, both ends of the bottom surface of the rail are respectively connected to the two side rail plates. The slider 3 is located between the two side rail plates, and both sides of the slider 3 are respectively arranged to abut against the two side rail plates.

[0046] In this way, the two side rails guide and limit the movement of the slider 3, so that the slider 3 moves in a straight line, thereby ensuring the alignment of the paddle 4 with the adjustment hole 11 and ensuring that the paddle 4 switches positions along different adjustment holes 11.

[0047] The paddle 4 and the slider 3 are integrally formed to achieve the cooperation between the slider 3 and the paddle 4. The slider 3 moves, causing the paddle 4 to move, thus achieving the switching of the hand strap's state.

[0048] Alternatively, the paddle 4 and the slider 3 can be arranged separately; this allows the slider 3 and the paddle 4 to work together, so that the slider 3 moves and drives the paddle 4 to move, thus switching the state of the hand strap. Example

[0049] The paddle-type hand strap bracket includes two paddle pieces 4, which are arranged at intervals and are synchronously installed on the slider 3. The adjusting rail piece 1 has two rows of adjusting holes, each row including multiple adjusting holes 11. The two paddle pieces 4 are arranged in a one-to-one correspondence with the two rows of adjusting holes, and the two paddle pieces 4 are synchronously embedded in one of the adjusting holes 11 of the two rows of adjusting holes.

[0050] In this way, with the combined action of the two paddles 4 and the two rows of adjustment holes, the movement of the slider 3 becomes smoother and helps to improve the user's control feel.

[0051] The paddle 4 and the slider 3 are integrally formed to achieve the cooperation between the slider 3 and the paddle 4. The slider 3 moves, causing the paddle 4 to move, thus achieving the switching of the hand strap's state.

[0052] Alternatively, the paddle 4 and the slider 3 can be arranged separately; this allows the slider 3 and the paddle 4 to work together, so that the slider 3 moves and drives the paddle 4 to move, thus switching the state of the hand strap. Example

[0053] The paddle-type hand strap bracket includes an adjustment rail component 1, a hand strap component 2, a slider 3, and multiple paddle components 4. The adjustment rail component 1 is assembled or integrally formed with the protective shell. The slider 3 is docked with the hand strap component 2 and is movably assembled with the adjustment rail component 1. The slider 3 is driven by a driving force to move relative to the adjustment rail component 1. The movement of the slider 3 causes the hand strap component 2 to bend or unfold. Each paddle component 4 is respectively installed on the adjustment rail component 1. The slider has an adjustment hole 11, which is embedded in one of the paddle components 4.

[0054] In this way, when the user switches the state of the wrist strap 2, the user applies a pushing force to the slider 3, causing the adjustment hole 11 of the slider 3 to disengage from the paddle 4. Then, with the continued application of the pushing force, the user switches to another paddle 4 until the adjustment hole 11 of the slider 3 is engaged with the other paddle 4. This allows the wrist strap 2 to switch between a bent support state and an unfolded storage state, improving the user's pushing feel on the slider 3, thereby improving the user's control over the switching of the state of the wrist strap 2 and the user's operating experience with the wrist strap bracket.

[0055] The lever component 4 and the rail adjustment component 1 are integrally formed and arranged to achieve the cooperation between the rail adjustment component 1 and the lever component 4, which facilitates the layout of the lever component 4.

[0056] Alternatively, the lever component 4 and the rail adjusting component 1 can be arranged separately and connected together; this allows for the cooperation between the rail adjusting component 1 and the lever component 4, and facilitates the layout of the lever component 4.

[0057] The paddle-type hand strap bracket includes two paddle pieces 4, one of which is arranged at the end and the other is arranged in the middle, so as to realize the positioning in the unfolded storage state and the positioning in the bent support state.

[0058] Each lever component 4 is arranged at intervals along the length of the adjusting component 1, so that the hand strap component 2 has different degrees of bending support state to meet different support requirements.

[0059] The paddle-type hand strap bracket includes four paddle pieces 4, which are arranged at intervals along the length of the adjusting rail piece 1, so that the hand strap piece 2 can have different degrees of bending support state to meet different support requirements.

[0060] The slider has at least one adjustment hole 11. The slider 3 can be positioned by cooperating with the adjustment hole 11 and the paddle 4.

[0061] The slider has an adjustment hole 11, which, in conjunction with the paddle 4, allows for the positioning of the slider 3.

[0062] The slider has two adjustment holes 11, which are arranged at intervals along the pushing direction. The slider 3 can be positioned by the cooperation of the adjustment holes 11 and the paddle 4.

[0063] The slider has three adjustment holes 11, which are arranged at intervals along the pushing direction. The slider 3 can be positioned by the cooperation of the adjustment holes 11 and the paddle 4. Example

[0064] The adjusting component 1 includes two side rail plates, which are arranged at intervals and corresponding to each other. The slider 3 is located between the two side rail plates. The side rail plates are arranged in a long strip shape and have multiple adjusting holes 11. The slider 3 has a side block surface, which is arranged corresponding to the side rail plate. The paddle 4 extends to the outside of the side block surface and is embedded in one of its adjusting holes 11.

[0065] By cooperating with the adjustment hole 11 of the side rail plate, the tactile feedback of the slider 3 is improved, the user's push feel of the slider 3 is improved, and thus the user's control over the state switching of the hand strap 2 is improved, as well as the user's operating experience of the hand strap bracket is improved. Example

[0066] Multiple adjustment holes 11 are formed simultaneously on the two side rails. The paddle-type hand strap bracket includes two paddle pieces 4. The two paddle pieces 4 are respectively set on both sides of the slider 3. Along the slider 3, the two paddle pieces 4 are symmetrically arranged, and the two paddle pieces 4 are respectively embedded in the adjustment holes 11 of the two side rails.

[0067] This improves the stability of slider 3's movement and prevents slider 3 from wobbling during movement. Example

[0068] The paddle-type hand strap bracket includes two sliders 3, which are arranged at opposite ends. The hand strap component 2 includes a first strap plate and a second strap plate. The hand strap component 2 is located between the two sliders 3, and the two sliders 3 are respectively arranged in a mating arrangement with the first strap plate and the second strap plate.

[0069] In this way, when users need to switch the stand status, they can choose to push one slider 3 or push both sliders 3 simultaneously; this improves the user's control method, making it more practical and easy to operate, and enhancing the user's experience of operating the stand.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
