Tablets, not available for tablets of all sizes.

Accordingly, it is an object of the present invention to provide a clamping device that is not limited in size.

Thus, the novel holding device comprises a pivot seat, a first lower clamp arm, a second lower clamp arm, and an upper clamp arm.

The hub includes a seat that surrounds an axis.

The first lower clamp arm extends downward from the hinge seat and is rotatable relative to the base body about the axis. The first lower clamp arm includes a first positioning portion that protrudes forward.

The second lower clamp arm extends downward from the hinge seat and is rotatable relative to the base body about the axis, and the second lower clamp arm includes a second positioning portion that protrudes forward.

The upper clamping arm is slidably disposed on the pivot seat, and includes an upper positioning portion protruding forwardly, the first positioning portion and the second positioning portion And the upper positioning portion jointly defines a clamping space.

The utility model has the beneficial effects that: in use, the first lower clamping arm and the second lower clamping arm can adjust the clamping range of the clamping space in the longitudinal direction by rotating, and the upper clamping arm can be used up and down The sliding adjustment adjusts the clamping range of the clamping space in the height direction, so the clamping device can be applied to different size tablet computers to achieve an unrestricted use effect.

The foregoing and other technical aspects, features, and advantages of the present invention will be apparent from the following description of the preferred embodiments.

As shown in FIGS. 1, 2, and 3, the preferred embodiment of the present clamping device 200 is adapted to clamp and hold a tablet computer 90. The clamping device 200 includes a pivot base 20 and a first lower clamp arm 30. A second lower clamp arm 40, an upper clamp arm 50, a top support unit 60, a cushion unit 70, and a rear support arm 80.

The hinge base 20 includes a seat body 21 surrounding an axis X, a through hole 22 extending vertically through the seat body 21, and a hinge hole 23 extending through the seat body 21 along the axis X.

The first lower clamp arm 30 extends downward from the hinge seat 20 and is rotatable relative to the base body 21 about the axis X. The first lower clamp arm 30 includes a seat body 21 disposed thereon. The first turntable 31, a first arm body 32 extending downward from the first turntable 31, and a first positioning portion 33 projecting forwardly and located at the first arm body 32.

The first turntable 31 has a first upper portion spaced apart in the rotational direction The stopping portion 311 and a first lower stopping portion 312.

The first positioning portion 33 has a first positioning surface 331 facing rearward, and a first positioning opening between the first positioning surface 331 and the first arm body 32 and extending in the direction of the first arm body 32. 332.

The second lower clamp arm 40 extends downward from the hinge seat 20 and is rotatable relative to the base body 21 about the axis X. The second lower clamp arm 40 includes a side disposed on the seat body 21 and along the axis 21 The axis X is stacked on the second turntable 41 of the first turntable 31, a second arm body 42 extending downward from the second turntable 41, and a second forwardly projecting portion of the second arm body 42 Two positioning portions 43.

As shown in FIGS. 1, 6, and 7, the second turntable 41 has a second upper stop portion 411 and a second lower stop portion 412 spaced apart from each other in the rotational direction. The first upper stop portion 311 and the The second upper stopping portion 411 can abut against the upward rotation of the second lower clamping arm 30 and the second lower clamping arm 40. The first lower stopping portion 312 and the second lower stopping portion 412 can The downward rotation of the first lower clamp arm 30 and the second lower clamp arm 40 abut each other to limit the amplitude of the upward rotation and the downward rotation.

The second positioning portion 43 has a second positioning surface 431 facing rearward, and a second positioning opening between the second positioning surface 431 and the second arm 42 and extending in the direction of the second arm 42 432. As shown in FIG. 8 , the first positioning opening 332 and the second positioning opening 432 can provide the lead angle of the tablet 90 to achieve a better fixing effect.

As shown in Figures 1, 2 and 3, the upper clamp arm 50 can be slid up and down. The pivot base 20 includes a slide bar assembly 51 extending through the through hole 22, an upper positioning portion 52 disposed on the top of the slide bar group 51 and projecting forwardly, and a seat portion 21 disposed on the base member 21. And abutting the slider 53 of the slider group 51, and a slip-proof knob 54 screwed to the back surface of the slider 53 and protruding rearwardly of the seat body 21, the first positioning portion 33, the first The two positioning portions 43, and the upper positioning portion 52 collectively define a clamping space.

The slider set 51 has a long through hole 511 extending upward and downward, and a lower stop portion 512 opposite to the upper positioning portion 52 and capable of abutting against the stop slider 53.

The upper positioning portion 52 has a rearward facing upper positioning surface 521 and an upper positioning groove 522 between the upper positioning surface 521 and the slider group 51.

The stop slider 53 is located in front of the slider group 51.

The anti-slip knob 54 is screwed to the stop slider 53 through the long through hole 511. When the user rotates the anti-slip knob 54 and causes the stop slider 53 to be pressed toward the slide bar group 51, the slide bar The group 51 is fixed. When the user rotates the anti-slip knob 54 and causes the stop slider 53 to move away from the slider group 51, the slider group 51 can freely slide up and down, allowing the user to adjust the upper positioning portion 52. The height, but the height of the upward pull, is limited by the top stop of the lower stop 512 and the stop slider 53 to avoid the upper clamp arm 50 being withdrawn from the base 21.

The top support unit 60 includes a top support block 61 located in the front and facing forward of the clamping space, and an adjusting button 62 screwed to the back of the top support block 61. The top support block 61 is matched with the adjusting button 62. Rotation produces forward or backward .

In this embodiment, the top support unit 60 is combined in the hub 20 and the number is only one; when the clamping device 200 is actually manufactured, the top support unit 60 can also be combined in the first lower clamp arm 30, The second lower clamp arm 40, or the upper clamp arm 50, and the top support unit 60 are not limited to one (not shown).

The top stay 61 is located in front of the hinge hole 23.

The adjusting button 62 is disposed in the hinge hole 23. As shown in FIGS. 4 and 5, when the user rotates the adjusting button 62 and causes the top stay 61 to move forward, the top stay 61 can face the flat plate. Pressing the back surface of the computer 90 causes the tablet 90 to abut against the upper positioning surface 521, the first positioning surface 331, and the second positioning surface 431, thereby achieving the effect of fixing the tablet 90. When the user turns the adjustment button 62 and causes the top stay 61 to move forward, the tablet 90 can be released from the fixed state.

As shown in FIGS. 1 , 4 , and 5 , the cushion unit 70 includes a plurality of the top support blocks 61 , the first lower clamp arm 30 , the second lower clamp arm 40 , and the upper clamp arm 50 . The cushion 71 faces the clamping space for providing a non-slip and shockproof use effect.

The rear support arm 80 is pivotally connected to the base body 21 and can be rotated backward to provide support behind the seat body 21.

As shown in FIGS. 2, 8, and 9, in use, the first lower clamp arm 30 and the second lower clamp arm 40 can adjust the clamping range of the clamping space in the longitudinal direction by rotating, the upper clamp The arm 50 can adjust the clamping range of the clamping space in the height direction by sliding up and down, so the clamping device 200 can be applied. It can be used on different sizes of tablets to achieve unrestricted use.

However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the present invention and the contents of the specification are all It is still within the scope of this new patent.
