It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

In order to solve the problem that the clamping device cannot be used for adaptive clamping of different handheld devices in the prior art, the application provides an electric clamping device of the handheld device.

As shown in fig. 1 to 8, the electric clamping device of the handheld device in the present application includes a housing 10, a clamping structure 20, a pressing portion 30, and a driving portion 40. The housing 10 has a receiving cavity; the clamping structure 20 comprises at least two oppositely arranged clamping arms 21, the two clamping arms 21 can move relatively, and clamping ends of the two clamping arms 21 respectively extend out of two sides of the shell 10 and can clamp the equipment to be clamped; the pressing part 30 is movably arranged in the accommodating cavity and located between the two clamping arms 21, the surfaces of the pressing part 30, facing the pressing ends 211 of the two clamping arms 21, are respectively provided with a pushing surface 31, the distance between the two pushing surfaces 31 is gradually changed along the height direction of the shell 10, and when the pressing part 30 is switched between a pressing position and a releasing position, the pressing ends 211 of the clamping arms 21 are kept attached to the pushing surfaces 31, so that the two clamping arms 21 are relatively movable; the driving part 40 is in driving connection with the pressing part 30 to switch the pressing part 30 between a pressing position and a releasing position, thereby realizing the releasing or clamping of the device to be clamped.

When the electric clamping device of the handheld device with the structure is used, the device to be clamped can be clamped through the clamping structure 20 due to the clamping structure 20. And, under the effect that the driving part 40 drives the pressing part 30, before the device to be clamped is placed into the electric clamping device of the handheld device, the pressing part 30 pushes the pressing end 211 of the clamping arm 21, so that the two oppositely arranged clamping arms 21 move in the direction away from each other, and the device to be clamped can be placed into the electric clamping device of the handheld device. Then, the driving portion 40 drives the pressing portion 30 to switch from the pressing position to the releasing position, so that the two oppositely arranged clamping arms 21 can move toward the direction approaching each other, and the device to be clamped can be clamped. In addition, during the process of moving the two clamping arms 21 towards each other, the distance between the two clamping arms 21 is gradually reduced, so that the clamping of different types of equipment can be realized. Therefore, the problem that the clamping device can not be used for carrying out adaptive clamping on different handheld devices in the prior art is effectively solved by the electric clamping device for the handheld devices.

As shown in fig. 3 and 4, the pressing portion 30 is slidably disposed in the accommodating cavity, and a moving track of the pressing portion 30 is perpendicular to a moving direction of the holding arm 21. In one embodiment of the present application, the pressing part 30 moves in the height direction of the housing 10, and the pressing part 30 moves from bottom to top when the pressing part 30 is switched from the release position to the pressing position.

By this arrangement, when the driving portion 40 drives the pressing portion 30 to move, the clamping arm 21 can be released from the clamped device by pressing the convex surface section 312 against the clamping arm 21. When the contact position of the pressing end 211 and the pressing part 30 is provided with a convex surface section 312 and a transition to a concave surface section 311, the two clamping arms 21 can gradually clamp the device.

And it is also noted that in the present application there is a smooth transition between the concave face section 311 and the convex face section 312.

Specifically, the two pushing surfaces 31 are symmetrically arranged along the movement locus of the pressing portion 30. By this arrangement, the synchronism of the movements of the two oppositely disposed gripper arms 21 can be ensured. Thereby ensuring a more uniform force application to the two clamp arms 21.

Alternatively, the pressing part 30 has a guide rail 33, and the housing 10 has a guide groove 11 engaged with the guide rail 33; alternatively, the pressing portion 30 has a guide groove 11, and the housing 10 has a guide rail 33 engaged with the guide groove 11. The guide rail 33 and the guide groove 11 can effectively ensure that when the driving part 40 drives the pressing part 30 to move, the movement of the pressing part 30 does not deflect, and the movement of the pressing part 30 is more stable. Thereby guarantee that handheld devices's electronic clamping device's performance is more stable.

Through setting up like this, can also carry on spacingly to the direction of motion of centre gripping arm 21 to guarantee the stability performance who is used for handheld device's auto-lock clamping device, prevent that the equipment that is used for handheld device from rocking appearing in the auto-lock clamping device who is used for handheld device, and can also make the equipment atress by the centre gripping more even through setting up like this.

It should be noted that, in one embodiment of the present application, there are two holding arms 21, and the two holding arms 21 are disposed oppositely, and accordingly, the first guiding structure 12 is two and disposed corresponding to the two holding arms 21.

Specifically, the pressing end 211 of the clamping arm 21 has a pressing seat 212, and the clamping structure 20 further includes a plurality of tensioning structures 22, and the tensioning structures 22 are installed between the pressing seat 212 and the inner wall of the housing 10 to provide the clamping arm 21 with a restoring force from the open state to the retracted state. By this arrangement, when the pressing structure is switched from the pressing position to the releasing position, the two oppositely arranged clamping arms 21 can be moved towards each other by the corresponding tensioning structures 22 and clamp the device to be clamped.

As shown in fig. 3, 4 and 8, the pressing base 212 has an ejector protrusion 213 protruding toward the ejector surface 31. By this arrangement, clamping or unclamping of the clamp arm 21 to the device to be clamped can be achieved by the interaction between the ejector protrusion 213 and the pressing portion 30.

In one particular embodiment of the present application, the ejector protrusion 213 has an arc-shaped face. By this arrangement, when the ejector protrusion 213 interacts with the pressing portion 30, it is possible to reduce the smoothness of the gripper arm 21 during movement and reduce the resistance between the gripper arm 21 and the pressing portion.

As shown in fig. 2, an edge of the front cover structure of the housing 10 is recessed inward to form an accommodating recess 13, and at least a portion of the clamping arm 21 protrudes from the cavity and is located at the accommodating recess 13. By means of the arrangement, the clamping arm 21 can be effectively guaranteed to clamp equipment with smaller size, and therefore the electric clamping device of the handheld equipment is improved.
