[0021] The specific implementation process of this utility model is as follows: In use, the workpiece is first placed on the top plate 3, and then the hydraulic cylinder 6 is started. The output end of the hydraulic cylinder 6 drives the connecting seat 7 to move down. The connecting seat 7 will pull the hinge rod 81 to deflect it. The hinge rod 81 will pull the connecting column 5 and the clamping block 4 to move horizontally. At the same time, the connecting seat 7 will pull down the connecting rod 82. The connecting rod 82 drives the connecting sleeve 83 to move down. The connecting sleeve 83 drives the connecting rod 84 and the pressure block 85 to move down, so that the pressure block 85 contacts the workpiece. The pressure block 85 stops moving while the connecting sleeve 83 continues to move down. The connecting sleeve 83 drives the guide rod 86 to slide along the connecting rod 84. The connecting sleeve 83 presses down the first spring 87. Under the elastic action of the first spring 87, it will give the connecting rod 84 a downward push force, which can make the pressure block 85 press the workpiece. As the clamping block 4 moves horizontally, it can clamp the workpiece, so that the workpiece can be limited in both horizontal and vertical directions, improving the positioning stability of the workpiece during drilling.

[0022] When it is necessary to disassemble the clamping block 4, pull the lever 91 outwards. The lever 91 drives the connecting block 92 to move horizontally. The connecting block 92 slides along the fixed rod 93 and squeezes the second spring 94. The connecting block 92 also drives the insert block 97 to move horizontally. At the same time, the connecting block 92 drives the magnetic block 95 to move. When the magnetic block 95 is attracted to the magnet 96, the insert block 97 can be pulled out from the slot 98, which makes it convenient to replace the clamping block 4. The clamping block 4 of different shapes can be adapted to workpieces with different outer contours for clamping and positioning, improving clamping adaptability.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
