The manual grabbing clamp can realize the effect of large load and simple grabbing form, and has advantages of reliability, simplicity and low cost.

[0005] The technical scheme of the utility model is: the utility model discloses a PCB manual grabbing device, which comprises a bottom plate, four fixed supports are arranged at four corners of one side of the bottom plate, a group of grabbing heads are arranged in each fixed support, and holes are formed in each group of grabbing heads and fixed supports.

[0006] Further, an axle is arranged in the hole, and the grabbing head is fixed on the fixed support after the axle passes through the hole.

[0007] Further, a spring is arranged in the axle, and the spring is fixed between the fixed support and the grabbing head after passing through the axle.

[0008] Further, a handle rod is arranged between the two opposite fixed supports, and the two ends of the handle rod are fixed on the threaded holes formed in the fixed supports.

[0009] Further, positioning pins are arranged on the bottom plate near the two side handle rods, and the positioning pins are fixed on the lower side of the bottom plate.

[0010] Further, the middle of the bottom plate is hollow, and rectangular holes are formed on the two sides of the bottom plate.

[0011] Further, the fixed supports are fixedly arranged at the four corners of the upper end face of the bottom plate.

[0012] The working principle of the device is:

[0013] When no external force is applied, the spring in the middle of the fixed support pushes the grab head to slide to the two sides of the clamp, the grab head will always be under force, and be kept in the position on the outside, in a tensioned state.

[0014] When manually grabbing the PCB, the handle position of the bottom plate is aligned with the positioning hole of the PCB, the handle rod is manually pushed to the inside of the clamp, at this time the grab head is driven to move to the middle; at this time the end of the grab head and the grabbing hole position of the PCB are coincided, the clamp is moved downward, the positioning pin is inserted into the positioning hole of the PCB, and the end of the grab head is inserted into the hole of the PCB; at this time the handle rod is loosened, and the grab head returns to the initial position under the action of the spring, at this time the end of the four grab heads is clamped to the grabbing hole of the PCB, and the grabbing action is completed, and the handle position of the bottom plate can be moved to move the PCB.

[0015] Conversely, the PCB can be unlocked and placed in a designated position.

[0016] The above one action cycle can realize the grabbing and releasing actions of the manual plate taking clamp, so that the grabbing and placing purposes of the PCB are achieved.

[0017] The beneficial effects of the utility model are: 1, the operation space occupied by the manual grabbing clamp is small, the problem of interference between the clamping jaw and the components on the PCB due to space reasons can be improved, the use scene is wide, and the manual grabbing clamp has irreplaceable advantages over traditional clamping jaws; 2, mechanical clamping jaw locking is adopted, the structure is simple, the adaptability is strong, manual operation is easy to operate, and the utility model can be widely promoted; 3, compared with the existing clamping jaw, the manual grabbing clamp is simple, easy to manufacture, and the production cost is reduced.
