[0025] A bidirectional electric push rod 7 is fixedly installed on the inner wall of the shell 6, and a gripper clamp 8 is fixedly connected to the output end of the bidirectional electric push rod 7. A rotating block 9 is fixedly connected to the top of the shell 6, so that the gripping device can be easily adjusted. The motor 3 can be used as a power source to perform rotational direction adjustment on the gripping angle of the gripping device, so that the gripping device can cope with more usage situations, thereby improving the stability and work efficiency of the gripping, avoiding the risk of falling due to unstable gripping, etc., and meeting people's usage needs.

[0026] In this embodiment, a rotation groove 10 is opened on the front of the rocker arm 1, and the shape and size of the rotation groove 10 match the shape and size of the rotation block 9. The rotation block 9 cooperates with the rotation groove 10 so that the shell 6 is given a certain rotation support force after being rotated.

[0027] Example 2

[0028] On the basis of Example 1, a preferred embodiment of the grabbing device for precision mechanical parts provided by the utility model is as follows: Figures 1 to 4 As shown, there are two gripper plates 8, and the two gripper plates 8 are symmetrically arranged with the vertical center line of the housing 6 as the symmetry axis. The two gripper plates 8 can provide gripping force after being gathered together, so as to firmly grip the precision mechanical parts.

[0029] In this embodiment, the front side of the gripping splint 8 is provided with concave-convex grooves, which can increase a certain friction force, thereby making the gripping effect of the gripping splint 8 better and the gripping force stronger.

[0030] Furthermore, a bearing 5 is fixedly connected to the front of the rocker arm 1, and the rocker arm 1 is movably connected to the rotating shaft 4 through the bearing 5, and the bearing 5 can provide the rotating shaft 4 with sufficient rotational supporting force.

[0031] When in use, the grabbing device can be moved to the part to be grabbed through the rocker arm 1, and then the two-way electric push rod 7 is turned on to drive the grabbing splint 8 to gather and thereby grab the part. When the angle of the part is difficult to grab and there is a certain degree of difficulty in grabbing the angle, the motor 3 is turned on, and the motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the shell 6 to rotate, thereby driving the grabbing splint 8 inside it to adjust the rotation angle. After adjusting to the required angle, the motor 3 stops, and then the subsequent grabbing operation is performed, which meets people's usage needs.

[0032] To sum up, the grasping device for precision mechanical parts can achieve the purpose of easy adjustment. The motor 3 can be used as a power source to perform rotational direction adjustment on the grasping angle of the grasping device, so that the grasping device can cope with more usage situations, thereby improving the grasping stability and work efficiency, avoiding the risk of falling caused by unstable grasping, etc., and meeting people's usage needs.
