Referring to fig. 1 and 2, as a specific embodiment of the present invention, the fishing claw includes a support 110 having a cylindrical structure, and a lifting assembly 120 is disposed under the support 110. The lifting assembly 120 includes a cable 121 and a weight 122, one end of the cable 121 is fixed to the weight 122, and the other end extends through the bottom and top of the support 110 to above the support 110. The fishing grab further comprises a plurality of support assemblies 130 and a plurality of grabbing assemblies 140, and the plurality of support assemblies 130 and the plurality of grabbing assemblies 140 correspond one to one. The top of each support assembly 130 is rotatably connected to the outer sidewall of the support base 110, and a plurality of support assemblies 130 are uniformly arranged along the circumferential direction of the support base 110. One side of the top of each grasping assembly 140 is pivotally connected to the bottom of one of the support assemblies 130 and the other side of the top is pivotally connected to the bottom of the weight 122.

In this embodiment, the support 110 can be fixedly connected to the cable of the crane. The fishing grab has a certain weight, and when the support 110 is fixedly connected with the cable of the crane, the lifting of the fishing grab can be effectively controlled by controlling the lifting of the support 110. The lifting assembly 120 includes a cable 121 and a weight 122, when the cable 121 rises, the cable 121 can drive the weight 122 to rise, and the weight 122 can drive the other side of the top of each grabbing assembly 140 to rise. Here, it should be noted that the other side of the top of the grasping assembly 140 is raised at a speed greater than that of the support 110. As the other side of the top of each gripper assembly 140 is raised relative to the support base 110, the other sides of the bottoms of the plurality of gripper assemblies 140 are brought closer together. Each support assembly 130 is capable of effectively supporting one side to which each gripper assembly 140 is fixed during movement of the gripper assemblies 140. Thus, the plurality of grabbing components 140 cooperate with each other to effectively grab objects submerged in water. Then, the submerged object is separated from the water by the continuous rising of the cable 121. The object submerged in the water is not required to be carried out of the water surface through manpower, and the danger coefficient in the fishing process is effectively reduced.

In an embodiment of the present invention, each grabbing component 140 includes a first fixing plate 141 with a triangular plate structure and a claw piece 142 with a plate structure. The plurality of grasping assemblies 140 include a plurality of claw pieces 142, and the plurality of claw pieces 142 cooperate with each other to grasp an object submerged in water. The plane of the first fixing plate 141 is parallel to the axis of the support 110. One side of the top of the first fixing plate 141 is rotatably connected to one of the supporting members 130, and the other side of the top is rotatably connected to the bottom of the weight 122. One side of the first fixing plate 141 close to the supporting member 130 is fixed to one side of the claw piece 142. The plurality of fingers 142 are relatively divergent at the top and relatively close at the bottom.

Specifically, when an object is to be fished in water, the cable of the crane is fixedly connected with the support 110. The cable of the crane descends, and the fishing grab descends. When the bottom of the claw piece 142 contacts the river bed, the crane's cable and fishing dogs stop descending. At the same time, the cable 121 is fixedly connected to the clevis on the cable of the crane. Here, it should be noted that the distance between the weight 122 and the bottom of the support 110 is the largest during the descent of the fishing grab. Then, the cable of the crane rises, and the cable 121 is driven to rise, and the cable 121 carries the counterweight 122 to move upwards. The weight 122 rises faster than the support 110, and the distance between the weight 122 and the bottom of the support 110 gradually decreases. The rising weight 122 carries the other side of the top of the first fixing plate 141 upward. Here, it should be noted that the other side of the top of the first fixing plate 141 is raised at a higher speed than the support 110. At the same time, one side of the top of the first fixing plate 141 moves downward relative to the weight 122. Here, the rising speed of the top portion of first fixing plate 141 is smaller than the rising speed of mount 110. The support assembly 130 can support and fix one side of the top of the first fixing plate 141 when the other side of the top of the first fixing plate 141 moves upward. When the other side of the top of the first fixing plate 141 moves upward, the tops of the plurality of claw pieces 142 move away from each other, and the bottoms of the plurality of claw pieces 142 move closer to each other. The plurality of claw pieces 142 cooperate with each other to effectively grab the object to be fished. Then, the cable of the crane continuously rises until the object to be fished is separated from the water surface. One side of the claw piece 142 close to the first fixing plate 141 is a concave surface, and one side far from the first fixing plate 141 is a convex surface. Therefore, after the plurality of claw pieces 142 grab the object to be fished, the object is not easy to fall off from the fishing grab. The orthogonal projection of the claw piece 142 perpendicular to the axial direction of the support 110 is a triangular structure, and the cross section of the top of the claw piece 142 is larger, and the cross section of the bottom is smaller. Therefore, the objects to be fished can be easily picked up from the bottoms of the objects to be fished by the bottoms of the claw pieces 142, and the fishing efficiency is effectively improved.

In an embodiment of the present invention, each supporting member 130 includes a supporting rod 131, one end of each supporting rod 131 is rotatably connected to the supporting base 110 through a first connecting member 133, and the other end is rotatably connected to one side of a first fixing plate 141 of one of the grabbing members 140 through a second connecting member 132. Wherein each of the first connection assemblies 133 includes a second fixing plate of a plate structure, a first fixing shaft of a cylindrical structure, and a first sleeve of a cylindrical structure. One side of the second fixing plate is fixed to the support 110. Being close to the bottom of second fixed plate, the second fixed plate is equipped with first through-hole, uses fastener fixed connection first fixed axle and second fixed plate through first through-hole. Here, the first fixing shaft is a bolt, and the fastening member is a nut. The first sleeve is sleeved on the first fixed shaft and can rotate around the axial direction of the first fixed shaft. Each second connecting assembly 132 includes a second fixed shaft and a second sleeve of cylindrical construction. One side of the top of the first fixing plate 141 is provided with a second through hole through which the second fixing shaft and the first fixing plate 141 are fixedly coupled using a fastening member. The second sleeve is sleeved on the second fixed shaft and can rotate around the axial direction of the second fixed shaft. Here, the second fixing shaft is a bolt, and the fastening member is a nut. One end of each support rod 131 is fixed to the outer side wall of the first sleeve, and the other end is fixed to the outer side wall of the second sleeve. In the fishing process, the flexibility of each supporting component 130 is high, so that the supporting components can be matched with each other conveniently, and the fishing efficiency is greatly improved. The axis of each support rod 131 is at a predetermined angle to the axis of the support 110. Specifically, the preset angle is 0 to 45 degrees. Here, it should be noted that, in the process of descending the fishing grab, the preset angle is 45 degrees. In the process of salvaging and grabbing, the preset angle is gradually reduced.

In an embodiment of the present invention, the weight 122 is a cylinder structure, and the weight 122 is disposed coaxially with the support 110. Therefore, the balance of the fishing grab can be well kept in the using process of the fishing grab. In addition, the weight 122 may be replaced with a hydraulic unit or the like. Two third fixing plates are fixed at the bottom of the counterweight 122 and are arranged in a cross manner. Both sides of each third fixing plate are provided with a third through hole, the other side of the top of the first fixing plate 141 is provided with a fourth through hole, and the third fixing plate and the first fixing plate 141 are rotatably connected by a third rotating shaft through the third through hole and the fourth through hole. The corners of the first fixing plate 141 and the claw piece 142 are chamfered. The chamfering process can effectively prevent stress concentration. And, when the assembly, be difficult for the fish tail operating personnel. The support 110, the counterweight 122, the supporting component 130 and the grabbing component 140 are all made of iron-carbon alloy, and the impact resistance and the bending resistance of the iron-carbon alloy are strong, so that the service life of the fishing grab is effectively prolonged. The number of the supporting component 130, the grabbing component 140 and the claw sheets 142 is 3-5. Fewer support assemblies 130, grasping assemblies 140, and claw tabs 142 facilitate removal and installation. The greater number of support members 130, gripping members 140 and claws 142 provides a better fishing result for the fishing grab.

In one embodiment of the present invention, the lifting assembly 120 further comprises two parallel fixed pulleys 123 and two parallel movable pulleys 124. Two fixed pulleys 123 are arranged inside the support 110, and two movable pulleys 124 are arranged between the bottom of the support 110 and the top of the balancing weight 122. Two fixed pulleys 123 and two movable pulleys 124 are connected by a cable 121. Two fixed pulleys 123 and two movable pulleys 124 are wound around the cable 121 in a flower-through manner. The two fixed pulleys 123 cooperate with the two movable pulleys 124, effectively reducing the lifting force required when the cable 121 and the counterweight 122 rise. A suspension device is fixed to the top of the support 110, by which the support 110 can be suspended on a cable of a crane. The suspension device can be a universal rotary hanging ring or a chain with a circular ring structure. The hook is fixed on the cable of the crane, and the support 110 can be hung on the cable of the crane by using the hook and the hanging device, so that the fishing grab can be hung on the cable of the crane. Therefore, the fishing grab is greatly convenient to use.
