The first and second adjustment parts 1161, 1162 are respectively provided with a first hollow opening 11611 and a second hollow opening 11621, The first and second hollow openings 11611 and 11621 are respectively formed at the center of the first and second adjustment parts 1161 and 1162, and the first adjustment part 1161 is accommodated in the second adjustment part 1162 in a first direction X1 is movable, that is, the aforementioned first adjustment part 1161 is accommodated in the second hollow opening 11621 of the second adjustment part 1162, and its upper and lower sides are respectively pivoted with the corresponding upper and lower sides of the second adjustment part 1162 Suppose, in this embodiment, the first adjustment part 1161 and the second adjustment part 1162 are pivoted through multiple axes, that is, one axis passes through the upper side of the first adjustment part 1161 Together with the upper side relative to the second adjustment part 1162, the other axis passes through the lower side of the first adjustment part 1161 and is pivotally connected with the lower side relative to the second whole part, so that the first adjustment The part 1161 can rotate left and right in the second hollow opening 11621 of the second adjusting part 1162 (ie, move in the first direction X1). The first direction X1 in this embodiment is described as the X-axis direction.

The aforementioned fixing portion 1164 defines a third hollow opening 11641, the third hollow opening 11641 is formed at the center of the fixing portion 1164, and the aforementioned second adjusting portion 1162 is accommodated in the fixing portion 1164 and arranged in a second direction Y1 movable, that is, the aforementioned second adjustment part 1162 is accommodated in the third hollow opening 11641 of the fixed part 1164, and its left and right sides are respectively pivoted with the left and right sides of the corresponding fixed part 1164. For example, the second adjusting part 1162 and the fixing part 1164 are pivoted through multiple axes, that is, one axis passes through the upper side of the second adjusting part 1162 and the left side of the fixing part 1164. The sides are pivotally connected together, and the other axis passes through the right side of the second adjusting part 1162 and is pivotally connected with the right side opposite to the fixing part 1164, so that the second adjusting part 1162 can be positioned on the second side of the fixing part 1164. The three hollow openings 11641 rotate upwards and downwards (that is, move in the second direction Y1). The second direction Y1 in this embodiment is described as the Y-axis direction, and the aforementioned first adjustment part 1161 will move along with the second adjustment part 1162 in the second direction Y1, that is, in the third hollow opening 11641 When the opening of the second adjustment part 1162 is forced to rotate upwards (or downwards), the first adjustment part 1161 in the second hollow opening 11621 will also go up together with the second adjustment part 1162 Turn (or turn down).

Referring to Fig. 1, Fig. 3A, Fig. 3B, and refer to Fig. 4B supplementedly, the aforementioned grasping adjustment unit 11 is accommodated in the first adjusting unit and moves in a third direction Z1, that is, the grasping adjustment unit 11 The movable part 111 of the first adjustment unit is accommodated in the first hollow opening 11611, and the plurality of external threads 1111 on the movable part 111 are screwed with the plurality of internal threads 11613 on the inner periphery of the first hollow opening 11611, The movable part 111 of the grasping adjustment unit 11 can be rotated (or rotated) forward and backward in the first hollow opening 11611 of the first adjustment unit (that is, movable in the third direction Z1), and in this embodiment The third direction Z1 is described as the Z-axis direction. Wherein the aforementioned grip adjustment unit 11 will follow the movement of the first and second adjustment parts 1161, 1162 in the first and second directions, that is, the first adjustment part 1161 in the second hollow opening 11621 is forced to turn to the left When moving (or turning to the right), the grasping adjustment unit 11 in the first hollow opening 11611 will also be rotated to the left (or turning to the right) by the first adjustment part 1161 at the same time, and then the When the opening of the second adjusting part 1162 in the third hollow opening 11641 is forced to rotate upwards (or downwards), the first adjusting part 1161 in the second hollow opening 11621 and the upper part grab the adjustment unit 11 It will also be rotated upwards (or downwards) by the second adjustment part 1162 at the same time.

Therefore, when the assembler wants to adjust (or fine-tune) the virtual keyboard image projected by the projection module 2 to a certain inclination angle (such as about 30 degrees), the assembler needs to screw in the movable part 111 of the grasping adjustment unit 11 ( or unscrew) rotation, so that the movable part 111 rotates forward (or backward) in the first hollow opening 11611, and the projection module 2 grasped (or clamped) by the grasping part 113 is simultaneously With the rotation (or rotation) of the movable part 111, the angle direction of the virtual keyboard image projected by the projection module 2 is adjusted.

If the assembler wants to adjust (or fine-tune) the projected virtual keyboard image to the left (or right), then the first adjustment part 1161 in the second hollow opening 11621 needs to be adjusted to the left ( or to the right) to make the first adjustment part 1161 rotate leftward (or rightward) in the second hollow opening 11621 after receiving force, and at the same time, the first adjustment part 1161 and the grasping adjustment unit 11 And the projection module 2 captured on it will also rotate to the left (or to the right), and then adjust the virtual keyboard image projected by the projection module 2 to move to the left (or to the right).

If the assembler wants to adjust the projected virtual keyboard image in the forward direction (or backward direction), then it is necessary to adjust the downward direction (or upward direction) of the second adjustment part 1162 in the third hollow opening 11641 Push to make the second adjusting part 1162 turn down (or turn up) in the third hollow opening 11641 after receiving the force, and at the same time, the first adjusting part 1161 and the grasping adjustment unit 11 and the projection grasped on it The module 2 will also rotate downwards (or upwards), and then adjust the projection module 2 to project the virtual keyboard image to move forward (or backward). Wherein the above moving in the forward direction means that the projection module 2 moves the projected virtual keyboard image towards its own direction, and the above moving in the backward direction means that the projection module 2 moves the projected virtual keyboard image away from itself.

Therefore, the grasping adjustment unit 11 and the adjustment unit 116 of the present invention constitute the three-dimensional grasping adjustment structure 1, which is applied to adjust the design of the projection module 2, so that it can effectively achieve convenient projection of the grasping projection module 2. The image of the virtual keyboard is adjusted (or fine-tuned), thereby effectively avoiding the effect of covering the projection light of the projection module 2 (that is, projecting the image of the virtual keyboard) during the adjustment process, and achieving high adjustment accuracy and easy mass production Effect.
