[0008] Three sets of bridging sliding frames and three sets of bridging limiting frames are respectively hinged to the inner sides of the middle and upper parts of the three reinforcing connecting plates. An actuator is installed on the bottom inner side of each reinforcing connecting plate for clamping parts.

[0009] The actuator includes a support limiting block and a reinforcing connecting frame. The support limiting block is an L-shaped block with two platforms, bracket A and bracket B, machined on the horizontal part to support the part from the bottom. Multiple sets of screw holes B are opened at the bottom of the horizontal part. The vertical part is a limiting plate to limit the part from the outside. Multiple sets of screw holes A are opened on the limiting plate. The reinforcing connecting frame is formed by bending bracket A and bracket B at right angles. Multiple sets of screw holes D and C are opened on bracket A and bracket B respectively. The reinforcing connecting frame is located outside the support limiting block and is fixed to screw holes B and screw holes A respectively by screw assembly A. Reinforcing angle plates are welded to the bent ends of bracket A and bracket B for reinforcement.

[0010] A crash barrier is installed at the bottom of the bridging sliding frame. Multiple sets of screw holes F are opened on the crash barrier, and it is installed at the bottom of the bridging sliding frame by countersunk screws.

[0011] Multiple sets of through holes A, B and C are respectively opened at the top, bottom and middle of the reinforcing connecting plate. The fixed end of the connecting hinge B is installed in through hole A, the fixed end of the connecting hinge A is installed in through hole C, and through hole B is connected to screw hole C and screw hole A through screw assembly B.

One end of the bridging limit frame is a straight rod with a through hole J at the end, and the other end has a bent end with two through holes I at the end of the bent end. Through holes I and through holes J are respectively hinged to through holes H and rotating hinge B.

[0014] The connecting hinge B and the connecting hinge A have the same structure; the connecting hinge B includes a fixed end and a U-shaped end A; the fixed end has a screw hole E and is fixed to the reinforcing connecting plate by a screw assembly C; the U-shaped end A has a through hole D and is hinged to the rotating hinge A or the rotating hinge B.

[0019] This utility model provides an adaptive universal lifting tool. Employing a universal design concept, the clamping area can freely change according to the size of the part. Three extendable clamping points achieve a certain degree of versatility, improving handling safety and reducing labor costs. The tool connects a bridging limiter and a fixing block, which function as limiting devices within the lifting tool, maintaining a fixed relative position. A sliding guide rod slides through the center hole of the sliding fixed end, thereby driving the actuator to move, achieving the universal lifting function. A compression spring keeps the lifting tool in the open state even when stationary.

[0020] This utility model's support and limiting block is made of polyurethane, a soft material that effectively protects parts from scratches during transport. Its arc-shaped, hook-like design provides added stability, especially for specialized round parts. A reinforcing connecting frame partially encloses the support and limiting block, effectively enhancing its strength and increasing its service life. The reinforcing connecting plate is made of aluminum alloy, making it lightweight and reducing the overall weight of the lifting device, thus making it more convenient to use. The reinforcing connecting plate serves as a bridge connecting the actuator and control ends of the entire mechanism. The connecting hinge is also made of aluminum alloy, making it lightweight, and features inlaid bushings within the holes to increase wear resistance and extend its service life. The anti-collision baffle is made of polyurethane and is connected to the bridging sliding frame via countersunk screws to prevent scratches on the workpiece during lifting.
