[0026] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] In daily life, the most common easily scattered objects on elevated roads include bird nests, clumps of plastic bags, etc. Figure 1 As shown. Based on field experience, bird nests built on elevated structures are often surrounded by ribbons, thatch, and other strips of debris. Existing bird-catching tools simply have barbs 13 on the gripper 1, which fail to effectively remove these strips along with the nest. In fact, the nest may scatter due to the traction of these strips during the grasping process. Furthermore, for bird nest-catching devices that heavily utilize motors, cameras, and other power-dependent components, there is a risk of electrical discharge.

[0028] Based on this, the present invention provides a device for grasping easily scattered and disorderly objects on elevated structures. Please refer to [reference needed]. Figures 2 to 6 The device includes a gripper 1 and a gripper drive 2. The gripper 1 is mounted on the gripper drive 2, which controls the gripper 1 to tighten inward or open outward. The gripper 1 includes at least two gripper assemblies arranged opposite each other, and the gripper assembly includes a first gripper 11 and a second gripper 12. One end of the first gripper 11 is connected to one end of the second gripper 12 and forms a first included angle at the connection point. The other end of the first gripper 11 is provided with a barb 13. The first gripper 11 has a first rack structure 14 extending from the middle to both ends on its inward side. The second gripper 12 has a second rack structure 15 extending from the middle to both ends on its outward side. The second gripper 12 is connected to the gripper drive 2.

[0029] Understandably, the design of the barb 13 and the first rack structure 14 allows the gripper 1 to firmly grasp loose debris while preventing it from slipping under limited gripping force. The debris also rotates with the gripper 1. During rotation, the second rack structure 15 hooks and coils around ribbons, thatch, and other strips surrounding the loose debris, effectively collecting them and maintaining the integrity of the debris, thus improving the removal efficiency of loose debris on overhead structures. The rotation operation can be manually controlled by the operator, making it simple and convenient.

[0030] In some embodiments, such as Figure 3As shown, the first gripper 11 comprises a first long strip plate 111 and a second long strip plate 112; one long side of the first long strip plate 111 and one long side of the second long strip plate 112 are connected, and a second included angle is formed at the connection; and a first rack structure 14 is arranged on the other long side of the first long strip plate 111 and the other long side of the second long strip plate 112. The first gripper 11 adopts a bending structure composed of the first long strip plate 111 and the second long strip plate 112, and the first rack structure 14 is arranged on the first long strip plate 111 and the second long strip plate 112, thereby effectively increasing the contact area with the easily-dispersed objects and making the gripping more stable; and the bending design makes it not cause excessive damage to the basic form of the easily-dispersed objects when pressing the easily-dispersed objects.

[0031] In some embodiments, as shown in Figure 3 and Figure 5 As shown, the clamping jaw driving member 2 comprises a telescopic driving member 21, a movable seat 22 and a connecting rod 23; the movable seat 22 is arranged on the movable end of the telescopic driving member 21, and the movable seat 22 is located between the gripper assemblies; the connecting rod 23 corresponds to the second gripper 12 one by one, one end of the connecting rod 23 is hinged to the movable seat 22, and the other end is hinged to the second gripper 12, and the end of the second gripper 12 away from the first gripper 11 is hinged to the telescopic driving member 21; when the telescopic driving member 21 extends forward, the movable seat 22 drives the clamping jaw 1 to tighten inward; when the telescopic driving member 21 retracts, the movable seat 22 drives the clamping jaw 1 to open outward. In this way, the torque change is realized by the hinged cooperation between the movable seat 22, the connecting rod 23 and the second gripper 12.

[0032] In some other embodiments, the telescopic driving member 21 comprises an outer sleeve rod 211 and an inner telescopic rod 212; the outer sleeve rod 211 is sleeved on the inner telescopic rod 212, the movable seat 22 is arranged on the upper end of the inner telescopic rod 212, and the end of the second gripper 12 away from the first gripper 11 is hinged to the upper end of the outer sleeve rod 211. Unlike the driving mode of a motor, this embodiment adopts manual control, that is, the operator holds the outer sleeve rod 211 with one hand and holds the inner telescopic rod 212 with the other hand, and controls the telescopic movement of the inner telescopic rod 212 to open or tighten the clamping jaw 1. Moreover, the presence of the outer sleeve rod 211 and the inner telescopic rod 212 can make the operator keep a certain distance from the overhead while grabbing the easily-dispersed objects, ensuring personal safety. At the same time, in order to facilitate operation, the lower end of the inner telescopic rod 212 passes through the outer sleeve rod 211; an anti-slip hand guard 215 is arranged on the lower end of the inner telescopic rod 212.

[0033] In some embodiments, as shown in Figure 5As shown, the telescopic driving member 21 further comprises a reset spring 213; the reset spring 213 is sleeved on the inner telescopic rod 212; the outer sleeve rod 211 is provided with a limiting baffle 214; one end of the reset spring 213 close to the movable seat 22 abuts against the limiting baffle 214, and the other end abuts against the inner telescopic rod 212; when the clamping jaw 1 is tightened inwardly, the reset spring 213 is in the original length state. The inner telescopic rod 212 is compressed or lengthened while moving telescopically; when the inner telescopic rod 212 is retracted, the movable seat 22 moves downward, the connecting rod 23 opens the second gripper 12, that is, the clamping jaw 1 is opened; at this time, the reset spring 213 is lengthened. When the force controlling the retraction of the inner telescopic rod 212 is removed, the reset spring 213 drives the inner telescopic rod 212 to reset, and the clamping jaw 1 is tightened again; the presence of the reset spring 213 enables the clamping jaw 1 to maintain the clamping state when clamping the easily scattered objects, so that the easily scattered objects are not easy to fall off.

[0034] In some embodiments, as shown in Figure 4 As shown, the outer sleeve rod 211 is provided with a strip-shaped limiting hole 24 extending in the axial direction of the outer sleeve rod 211; the inner telescopic rod 212 is provided with a limiting pin 25 at a position corresponding to the strip-shaped limiting hole 24; the limiting pin 25 is arranged through the strip-shaped limiting hole 24. The strip-shaped limiting hole 24 is provided with at least two clamping holes 26 distributed on the long side edge; the inner telescopic rod 212 can rotate relative to the outer sleeve rod 211, so that the limiting pin 25 enters or exits the clamping hole 26. It can be understood that the inner telescopic rod 212 can not only move telescopically relative to the outer sleeve rod 211, but also rotate. When the inner telescopic rod 212 moves telescopically, the limiting pin 25 moves in the strip-shaped limiting hole 24; by rotating the inner telescopic rod 212, the limiting pin 25 can be made to enter one of the clamping holes 26 on the long side edge of the strip-shaped limiting hole 24; under the limiting action of the clamping hole 26, the limiting pin 25 cannot move along the axial direction of the outer sleeve rod 211, that is, the inner telescopic rod 212 cannot move telescopically, so that the clamping jaw 1 is kept in a certain state. The limiting pin 25 falls into different clamping holes 26, which corresponds to keeping the clamping jaw 1 in different states. Moreover, since the inner telescopic rod 212 is connected with the movable seat 22, the connecting rod 23 and the clamping jaw 1, in order to enable it to rotate, a rotatable mounting seat can be designed for the part connecting the outer sleeve rod 211 and the second gripper 12 of the clamping jaw 1.

[0035] In some embodiments, the inner telescopic rod 212 comprises a movable rod 2121, a bearing 2123 and a limiting rod 2122; one end of the movable rod 2121 is connected with the movable seat 22, the other end of the movable rod 2121 is rotatably connected with one end of the limiting rod 2122 through the bearing 2123, and the limiting pin 25 is located on the limiting rod 2122. The presence of the bearing 2123 enables the inner telescopic rod 212 to rotate without rotating the whole body, but only rotating the part of the limiting rod 2122 with the limiting pin 25, thereby simplifying the fixing operation of the clamping jaw 1.
