One end of the first electric telescopic rod 1 passes through the shell 2 and is installed with a first connecting plate 3. A plurality of fixing plates 9 are fixed to the bottom outer wall of the shell 2 by bolts. A support plate 6 is slidably connected to the bottom end of the fixing plate 9. A protrusion 10 is fixed to one end of the supporting plate 6 by bolts. The protrusion 10 can limit the moving distance of the supporting plate 6 to prevent the supporting plate 6 from being detached from the fixing plate 9. A first spring 4 is welded on one side of the protrusion 10, and the first spring 4 is fixed to the fixed plate 9, a first pull rope 5 is installed on one side of the protrusion 10, and the other end of the first pull rope 5 is fixed to the first connecting plate 3, when the splint 8 clamps the object, the pressure sensor 18 contacts the object and detects the pressure of the splint 8 clamping the object, so that the first electric telescopic rod 1 is started, and the first electric telescopic rod 1 contracts to cause the first pull rope 5 to pull the support plate 6 to slide inward until the end points of the multiple support plates 6 contact each other, and the first spring 4 contracts, so that the support plate 6 protects the object clamped by the splint 8.

[0024] In the present invention, it should be noted that the clamping assembly includes a plurality of slide grooves 14, the slide grooves 14 are opened at the bottom of the shell body 2, a clamping plate 8 is slidably connected in the slide grooves 14, a second spring 13 is welded on the top part of the clamping plate 8 for facilitating the resetting of the clamping plate 8, and the second spring 13 is fixed to the slide grooves 14, a second pull rope 12 is installed on the top of the clamping plate 8, a second electric telescopic rod 16 is fixed to the top outer wall of the shell body 2 by bolts, a second connecting plate 11 is installed on the telescopic end of the second electric telescopic rod 16, and the second pull rope 12 is fixed to the second connecting plate 11, the second electric telescopic rod 16 is extended to make the second connecting plate 11 pull the second pull rope 12, so that the clamping plate 8 moves inward along the slide grooves 14, thereby making the plurality of clamping plates 8 clamp objects. The bottom inner wall of the shell 2 is fixed with multiple second guide frames 15 by bolts, the second pull rope 12 passes through the bottom of the second guide frame 15, and the second guide frame 15 is located at the top of the slide groove 14, and the second guide frame 15 can guide the second pull rope 12, and the first guide frame 7 is fixed with a first guide frame 7 by bolts on one side of the fixed plate 9, and the first pull rope 5 passes through the bottom of the first guide frame 7, and the first guide frame 7 can guide the first pull rope 5.

[0025] Working principle: when it is necessary to clamp the bagged object, the robot senses the position of the object through the optical fiber sensor 17, moves the device to the top of the clamped object, and then starts the second electric telescopic rod 16. The second electric telescopic rod 16 extends to make the second connecting plate 11 pull the second pull rope 12, so that the clamping plate 8 moves inward along the slide groove 14, and the second spring 13 contracts, so that the multiple clamping plates 8 clamp the object. At this time, the pressure sensor 18 contacts the object and detects the pressure of the clamping plate 8 clamping the object, so that the first electric telescopic rod 1 is started. The first electric telescopic rod 1 contracts to make the first pull rope 5 pull the support plate 6 to slide inward until the end points of the multiple support plates 6 contact each other, and the first spring 4 contracts, so that the support plate 6 protects the object clamped by the clamping plate 8. When the clamped object accidentally detaches from the clamping plate 8, it can fall directly onto the supporting component surrounded by the multiple support plates 6.
