[0008] Preferably, there are four springs in total, and all of the springs are fixedly connected to the moving rod.

[0009] Preferably, the specific shape of the mounting frame is an inverted C-shape.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: a rubber sheet, an active rack, a driven gear, a spring and a connecting rod, etc. are provided, and when the clamping jaws clamp an object, the two clamping jaws will simultaneously move toward the middle direction and close, and the various mechanisms will be linked during the movement of the clamping jaws. At this time, the two rubber sheets will simultaneously rotate toward the direction of the clamped object, and the two rubber sheets will tightly clamp the two sides of the object. At the same time, the two rubber sheets will also deform with the object due to the clamping force, so as to better fit the clamped object, thereby preventing the clamped object from falling off during the clamping process.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 The utility model provides a technical solution: a robot with a grasping and anti-falling structure, including a clamping rod 1, two clamping rods 1 are provided with a slide groove 2, the slide groove 2 is slidably connected with a moving rod 3, the opposite ends of the moving rod 3 are commonly fixedly connected with a clamping block 4, the slide groove 2 is fixedly connected with a spring 5, the bottom ends of the two clamping blocks 4 are fixedly connected with an active rack 6, the bottom ends of the two clamping rods 1 are fixedly connected with a mounting frame 7, the two mounting frames 7 are rotatably connected with a rotating rod 8, the two rotating rods 8 are fixedly connected with a connecting rod 9 at the position corresponding to the internal position of the mounting frame 7, the opposite sides of the two connecting rods 9 are fixedly connected with a mounting ring 10, the opposite sides of the two mounting rings 10 are provided with a rubber sheet 11, and the two rotating rods 8 are fixedly connected with a driven gear 12 at the position corresponding to the active rack 6.

[0017] Furthermore, there are four slide grooves 2 and four moving rods 3 in total.

[0018] Furthermore, the active racks 6 are meshedly connected with the driven gears 12 , so that the active racks 6 can drive the driven gears 12 to rotate.

[0019] Furthermore, there are four springs 5 ​​in total, and the springs 5 ​​are all fixedly connected to the moving rod 3 , so that the springs 5 ​​can drive the moving rod 3 to reset.

[0020] Furthermore, the specific shape of the mounting frame 7 is an inverted C-shape.

[0021] When the clamping block 4 touches the object, it will stop moving, and the clamping rod 1 will continue to move. When the clamping rod 1 moves, the spring 5 will contract, and the clamping rod 1 will also drive the mounting frame 7 to move in the direction of the clamping block 4. At the same time, the driven gear 12 will rotate due to the active rack 6 during movement, and the driven gear 12 will drive the rotating rod 8 to rotate. At this time, the two rotating rods 8 will drive the connecting rod 9 and the mounting ring 10 to rotate in the middle direction. The rotation of the mounting ring 10 will drive the rubber sheet 11 to rotate together. The two rubber sheets 11 will clamp the side walls of the object. As the clamping rod 1 moves, the two rubber sheets 11 will continue to rotate. The rotating rubber sheet 11 will be deformed due to the object, thereby achieving the best anti-slip effect. At this time, one side of the two clamping rods 1 will abut against one side of the clamping block 4, so that the clamping block 4 clamps the object with great force.
