The handle is hollow inside, the upper section of the central axis is inserted into the handle, and the lower section of the central axis is fixedly connected to the second chuck. The first chuck is sleeved outside the central axis and fixedly connected to the end of the handle. The central axis can move vertically relative to the first chuck. The side wall of the handle is provided with a first through hole and a second through hole. The first connecting rod passes through the first through hole, one end of which is rotatably connected to the handle, and the other end is connected to the grip arranged on the outside of the handle. The second connecting rod passes through the second through hole, one end of which is rotatably connected to the central axis, and the other end is connected to the grip.

[0006] Preferably, the hand-held clamping and picking tool provided by the present invention further includes a spring, and the spring is sleeved on the central axis.

[0007] Preferably, the first connecting rod is I-shaped, including a first horizontal section, a second horizontal section and a first vertical section, the first vertical end is inserted into the first through hole, the first horizontal section is fixed on the handle, and the two ends of the second horizontal section are rotatably connected to the side wall of the handle through pins.

[0008] Preferably, the second connecting rod is T-shaped, including a third horizontal section and a second vertical section, the second vertical section is inserted into the second through hole, the third horizontal section is fixed on the handle, and the end of the second vertical section is rotatably connected to the top of the central axis.

[0009] During operation, hold the grip and handle, tighten the four fingers, rotate the first connecting rod and the second connecting rod, move the grip closer to the handle, push the center shaft downward through the second connecting rod, and the center shaft moves downward with the second chuck. Since the position of the first chuck is fixed, the relative distance between the first chuck and the second chuck increases, and the chuck opens. When removing the workpiece, the four fingers return to the initial state, the center shaft moves upward under the action of the spring, the relative distance between the first chuck and the second chuck decreases, and the chuck is clamped to complete the clamping of the workpiece.

[0010] The beneficial effect of the technical solution of the present invention compared with the prior art is that the hand-held clamping and picking tool provided by the present invention is compact and portable, allowing operators to use the tool more conveniently, thereby improving production efficiency.
