[0025] As shown in [Fig.l] and [Fig.2], the clamping device with adjustable clamping thickness according to the present invention comprises: a base 10, two clamping arms 20, 30 and at least two clamping parts 40, 50. The base 10 has a placement surface 11 for placing electronic products; the two clamping arms 20, 30 are installed on the opposite sides of the base 10, at least one clamping arm 20 can move to approach or move away from the other clamping arm 30. Each clamping arm 20, 30 has at least one support 21, 31 at an end far from the base 10, and the support 21, 31 protrudes from the placement surface 11. The two clamping parts 40, 50 are respectively arranged on the support 21, 31 of the corresponding clamping arm 20, 30. The clamping part 40, 50 can move along the support 21, 31 to adjust the relative height with the placement surface 11.The two clamping parts 40 and 50 are responsible for clamping both sides of the electronic product, so that electronic products of different thicknesses can be well clamped by using the clamping device according to the present invention.

[0026] The clamping device according to the present embodiment is of the electric type, and the base 10 is provided with a motor and a gear for driving the clamping arm 20 and the clamping arm 30 to approach or move away from each other synchronously. However, the present invention is not limited to this, and the clamping device may also be manually operated, i.e., a spring may be provided inside the base 10 to provide power to the clamping arm 20 and the clamping arm 30 to move. Furthermore, the base 10 also comprises a stop 60, the stop 60 has at least one stop member 61 which protrudes from the placement surface 11. In the present embodiment, the stop 60 can also approach or move away from the base 10, and the position of the stop member 61 is perpendicular to the direction of movement of the clamping arms 20, 30.The function of the stopper 60 is to prevent the electronic products placed on the placement surface 11 from sliding downward, and since the above structures are in accordance with conventional structures, no further description will be provided.

[0027] The present invention is a clamping device with adjustable clamping thickness. It is mainly designed to allow the clamping parts 40, 50 to move up and down, and then adjust the height with the placement surface 11, as shown in [Fig.l]. As shown, the position of the clamping portion 40 and the clamping portion 50 is the highest, and can hold the thickest electronic product. As shown in [Fig.3], the clamping portion 40 and the clamping portion 50 are adjusted to the lowest position, which is suitable for thinner electronic products, so that the invention can be applied to a larger number of electronic products of different sizes.

[0028] The structure of the present invention is described in detail. [Fig.4] shows an exploded view of the present invention. Since the structure of the clamping portion 40 and the structure of the clamping portion 50 are similar, the description will focus on the clamping portion 40 provided on the clamping arm 20. Similarly, the clamping arm 30 and the clamping portion 50 also have the same structure as the clamping portion 40 and the clamping arm 20.

[0029] The clamping arm 20 is an L-shaped body in cross-section, and extends partially into the base 10. As described, the clamping arm 20 is driven by the motor and the gear in the base 10. The clamping arm 20 has the bracket 21 erected at the end far from the base 10, the bracket 21 protrudes from the placement surface 11, and the bracket 21 is responsible for installing the clamping portion 40 therein. Therefore, the clamping portion 40 can move along the bracket 21 in a direction perpendicular to the placement surface 11. Referring to [Fig. 5], the bracket 21 has a guide groove 22 facing away from the wall of the base 10, and the guide groove 22 passes through longitudinally.There is also a movable elastic upper part 23 located in the guide groove 22, the elastic upper part 23 must withdraw from the guide groove 22 when the external force is received and, when the external force disappears, the elastic force causes the elastic upper part 23 to move back inside the guide groove 22. This structure can be constructed in various ways, and the present embodiment only provides one for illustration, but it is not intended to be restrictive. In the present embodiment, the elastic upper part 23 is an arc-shaped metal elastic piece with a protruding part 231 in the middle. The holder 21 has a receiving groove 24 on the same wall as that where the guide groove 22 is located. The receiving groove 24 has an opening 241 and the opening 241 communicates with the guide groove 22.The elastic upper part 23 is restricted in the receiving groove 24, the protruding part 231 is located in the guide groove 22 through the opening 241. When an external force pushes the protruding part 231, the protruding part 231 should withdraw from the guide groove 22 and automatically return when the external force disappears.

[0030] In the present embodiment, the clamping portion 40 comprises a housing member 41, an intermediate member 42 and a cushion 43. The side wall of the member of housing 41 facing the base 10 has a protruding strip 411, and the side wall of the protrusion 411 has a plurality of positioning arc grooves 412. The side wall of the intermediate member 42 facing the housing member 41 has a chamber 421. The longitudinal dimension of the chamber 421 is larger than that of the support 21, and the transverse widths correspond to each other. After locking the housing member 41 with the intermediate member 42, the holder 21 will be confined in the chamber 421 to ensure that the clamping part 40 can move up and down without detaching from the holder 21. As shown in [Fig. 5], furthermore, after being locked, when pushed by an external force, the protruding strip 411 can slide up and down because it is located in the guide groove 22.By pressing one of the positioning arc grooves 412, the height of the clamping portion 40 on the support 21 can be fixed.

[0031] The pad 43 is located in the direction from the clamping portion 40 toward the base 10. More specifically, the pad 43 is fixed on the side wall of the intermediate member 42 toward the base 10. The pad 43 is a covering pad having an inverted L-shaped body in the vertical direction. The pad 43 is in contact with the electronic product during clamping to increase friction and prevent the surface of the electronic product from being scratched. In addition, the inverted L-shaped body also prevents the electronic product from falling after clamping. The pad 43 is made of a sponge or a soft colloid (such as silicone), and when adhered to the side wall of the intermediate member 42, the screw holes on the intermediate member 42 are covered, so that the clamping portion 40 has a more compact and pleasing appearance.

[0032] Furthermore, the clamping arm 30 and the clamping portion 50 are also constructed with the same structure. For example, the end of the clamping arm 30 away from the base 10 also has the holder 31, the holder 31 also has a guide groove 32, and a movable elastic upper part is disposed in the guide groove 32. The clamping portion 50 has a protruding strip 511 inside, and the protruding strip 511 is disposed with a plurality of positioning arc grooves 512 on the side wall. The clamping portion 50 is arranged in the guide groove 32 via the protruding strip 511, so that the clamping portion 50 can move up and down along the support 31. When the elastic upper portion is pressed against one of the positioning arc grooves 512, the height of the clamping portion 50 on the support 31 is temporarily fixed.

[0033] In addition, the clamping portion 50 also comprises a housing member 51, an intermediate member 52 and a cushion 53. The side wall of the housing member 51 facing the base 10 has a protruding strip 511. The side wall of the intermediate member 52 facing the housing member 51 has a chamber. After locking of the housing member 51 with the intermediate member 52, the support 31 will also be confined in the chamber to ensure that the clamping portion 50 can move up and down without detaching from the support 31. The cushion 53 is also disposed on the clamping portion 50 and faces the base 10.

[0034] In the aforementioned embodiment of the present invention, although each clamping arm only has one clamping portion, this is not limiting. A plurality of clamping portions can also be used as long as a plurality of protruding supports are erected. Furthermore, one clamping arm can have only one clamping portion, and the other clamping arm can have two clamping portions, to meet the needs of different products.

[0035] In summary, the clamping device according to the present invention comprises movable clamping arms 20, 30 on both sides of the base 10, to achieve the purpose of clamping or opening. In addition, the ends of the clamping arms 20, 30 away from the base 10 comprise the movable clamping portion 40 and the clamping portion 50 respectively for adjusting the height, and the clamping portion 40 and the clamping portion 50 are intended to clamp the two sides of the electronic product of different thicknesses to achieve a good clamping effect.

[0036] Although the present invention has been described with reference to its preferred embodiments, it will be apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention.
