referring to fig. 1 to 3, an electronic product clamping bracket is used for clamping a planar product such as a mobile phone and a tablet computer. The clamping device comprises a fixed seat for fixing the whole clamping support, a clamping device for clamping or supporting a product, and a connecting arm for connecting the fixed seat with the clamping device.

Wherein, clamping device includes box-shaped base plate 1, and base plate 1 has certain thickness and inside and has the accommodation space, locates telescopically first centre gripping subassembly 2 and second centre gripping subassembly 3 at 1 both ends of base plate, and locate connecting portion 4 at the base plate 1 back, connecting portion 4 be used for with the linking arm is connected, can be fixed connection or rotate the connection, when being fixed connection, then usually the linking arm is flexible arm of can buckling to make the whole certain angle of lateral rotation of support. The first clamping assembly 2 comprises a first pull rod 21 telescopically inserted in the substrate 1, a first clamping jaw 22 rotatably connected to the outer end of the first pull rod 21 and foldable towards the front surface of the substrate 1, and a limiting part 23 limiting the first clamping jaw 22 to be opened to be perpendicular to the substrate 1, wherein the front surface of the substrate 1 is further provided with a position avoiding groove 11 accommodating the first clamping jaw 22; the second clamping assembly 3 comprises a second pull rod 31 telescopically inserted in the substrate 1, and a second clamping claw 32 fixed at the outer end of the second pull rod 31 and perpendicular to the front surface of the substrate 1. The first pull rod 21 or the second pull rod 31 is inserted into the accommodating space of the substrate 1 and extends or retracts by a spring or an elastic band connected or abutted between the first pull rod and the second pull rod.

During the use, making the firm scene of product centre gripping, for example need violently the screen to watch or the centre gripping when the position of easy moving such as head of a bed, can manually open first jack catch 22, it is fixed with product both sides centre gripping through flexible first centre gripping subassembly 2 and second centre gripping subassembly 3 again, not only the difficult pine of product takes off, can vertically or transversely freely place moreover. And the scene of only needing the bearing product, for example the support is fixed when studying or watching at the desktop, then can make clamping device's second jack catch 32 be located the lower extreme for the bearing product, and first jack catch 22 is located the upper end of base plate 1, and first jack catch 22 folds to draw in to base plate 1 nature under the action of gravity this moment, does not influence the product and places, is equivalent to single-hand jack catch support, only needs one-hand operation, convenient to use.

The first clamping assembly 2 comprises a first pull rod 21 positioned in the middle, and first clamping jaws 22 arranged on two sides of the first pull rod 21; the second clamping assembly 3 comprises two groups of second pull rods 31 positioned on two sides of the first pull rod 21 and two groups of second clamping jaws 32 corresponding to the second pull rods 31, the two groups of second clamping jaws 32 are fixedly connected, the first pull rod 21 and the second pull rod 31 are inserted into the accommodating space of the substrate 1 in a staggered manner, so that the structure is compact, and the first clamping jaw 22 and the second clamping jaw 32 are both provided with two groups, so that the product is clamped more firmly and reliably; the first claw 22 and the first pull rod 21 are arranged in a staggered manner, so that the first claw 22 can be conveniently folded and accommodated in the avoiding groove 11 of the substrate 1, and the thickness space of the substrate 1 is not occupied.

Wherein, both sides connect through a pivot 221 between the first jack catch 22, first pull rod 21 has and is used for wearing to establish the shaft hole 211 of pivot 221, locating part 23 including radial protrusion in the spacing arris 231 of pivot 221 to and the indent shaping in being used for of shaft hole 211 inner wall is spacing the arc wall 232 of spacing arris 231. Only a limiting piece 23 is arranged between the first claw 22 and the first pull rod 21, so that the first claw 22 can be folded towards the base plate 1 under the action of gravity without elastic reset, and a product supported on the bracket can be prevented from being ejected out when the first claw 22 extends out elastically. In addition, the limiting edge 231 and the arc-shaped groove 232 of the limiting member 23 are both arranged inside the first pull rod 21, so that the integrity of the exterior is stronger.

The substrate 1 is provided with a sliding groove 12 in sliding fit with the first pull rod 21 and the second pull rod 31, a return spring 5 is connected between the first pull rod 21 and the substrate 1 and between the second pull rod 31 and the substrate 1, and a first limit buckle 213 and a second limit buckle 311 are respectively arranged between the inner ends of the first pull rod 21 and the second pull rod 31 and the sliding groove 12 to limit the first limit buckle and the second limit buckle from being pulled out of the sliding groove 12. The sliding grooves 12 limit the sliding tracks of the first pull rod 21 and the second pull rod 31, and the first claw 22 and the second claw 32 can be prevented from swinging to influence the clamping stability. The reset spring 5 has stronger reset capability and can provide stronger clamping force. The limit buckle can prevent the first clamping component 2 or the second clamping component 3 from being pulled away from the substrate 1 due to excessive pulling when in use.

The base plate 1 comprises a base 13 and a cover plate 14, the sliding groove 12 is convexly arranged on the top surface of the base 13, and a first fixing column 15 for fixing one end of the return spring 5 is arranged in the sliding groove 12; the first pull rod 21 and the second pull rod 31 are both in a long box shape with an opening at the inner end, and second fixing columns 212 for fixing the other end of the return spring 5 are arranged in the first pull rod 21 and the second pull rod 31. The substrate 1 adopts a split structure of the base 13 and the cover plate 14, and is convenient to produce. The first fixing column 15 and the second fixing column are adopted to fix the return spring 5, and the first pull rod 21 and the second pull rod 31 are arranged in a long box shape, so that the return spring 5 can be prevented from loosening, and the smoothness of the return spring 5 is ensured.

The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
