inner diameter of the workpiece, the mechanical arm 3 is uniformly arranged on the inner side of the workpiece, meanwhile, the adjusting plate rotates anticlockwise, because the first connecting rod 12 is connected with the adjusting plate belt through threads, in the process of rotating the adjusting plate anticlockwise, the first connecting rod 12 drives the adjusting plate to move upwards, because the clamping ball 14 fixedly connected with the first section rod is connected with the first circular groove 16 through a ball, in the process of rotating the adjusting plate anticlockwise, the circular rod cannot rotate along with the first connecting rod 12, because the second sliding block 18 fixedly connected with the supporting plate 17 is in sliding connection with the second sliding groove 22 on the inner wall of the mechanical arm 2, in the process of rotating the first connecting rod 12 anticlockwise, the supporting plate 17 drives the second sliding block 18 to slide upwards in the second groove 29, and meanwhile, the mechanical arm 2 opens, when a small workpiece needing galvanizing is grabbed, the workpiece is firstly placed on the inner side of a mechanical arm 2 which is uniformly arranged, the adjusting plate is rotated clockwise, in the process of rotating the adjusting plate clockwise, a supporting plate 17 is driven by a first connecting rod 12 to slide downwards, meanwhile, the mechanical arm 2 contracts inwards to clamp the workpiece for galvanizing, an adjusting column 1 is rotatably connected with the first connecting rod 12 through threads, when the mechanical arm 3 clamps the workpiece, the adjusting column 1 and the first connecting rod 12 are meshed and clamped through threads, the situation that the workpiece is grabbed by the mechanical arm 3 and the workpiece is loosened and falls off due to the fact that the first connecting rod 12 moves downwards when the mechanical arm 3 grabs the workpiece can be prevented, the inner diameter of the mechanical arm 2 can be adjusted at will in the process that the supporting plate 17 moves up and down, the workpiece with different inner diameters can be grabbed in the process, and the problem of grabbing trouble due to the different inner, when the manipulator 3 needs to be replaced, the pressing plate 32 at the bottom of the manipulator 3 is pressed, the pressing plate 32 drives the second section rod 33 to move upwards, meanwhile, the side rod 34 hinged through the rotating shaft moves upwards, when the side rod 34 completely enters the second groove 29, the manipulator 3 is pulled downwards, the manipulator 3 can be separated from the manipulator 2, so that the replacement of the manipulator 2 is realized, when the manipulator 2 is installed, the button 26 connected to the first slide block 21 is firstly pressed, in the process of pressing the button 26, the second connecting rod 25 fixedly connected above the button 26 drives the third slide block 24 in the third slide groove 23 to move upwards, in the process of moving the third slide block 24 upwards, gas in the third slide groove 23 is simultaneously extruded, the gas is transmitted into the second groove 29 through the air channel, meanwhile, the square 211 tightly attached to the inner wall of the second groove 29 in the second groove 29 is extruded, and the square 211 slides leftwards under the action of the gas, simultaneously, the sliding plate in the first groove is driven to move towards the inner side of the first groove, simultaneously, the sliding plate drives the clamping blocks uniformly arranged on the sliding plate to move towards the inner side of the first groove, the clamping blocks are arranged in the inner wall of the first sliding block 21, at the moment, the first sliding block 21 fixedly connected to the top of the mechanical arm 2 slides into the first groove, when the first sliding block 21 slides to a position needing to be adjusted, the button 26 is loosened, the clamping plate pops the first sliding block 21 out under the acting force of the spring to extend into the corresponding clamping groove 19, so that the clamping effect of the mechanical arm 2 is realized, because the fourth sliding block 37 is the same as the first sliding block 21 in structure, the long plate can be randomly adjusted in height in the first sliding groove 11, because the mechanical arm 2 is mutually matched with the first sliding block 21 to clamp the mechanical arm 2, when the mechanical arm 2 grabs a heavy workpiece, the mechanical arm 2 only needs to be, thereby causing damage to the mechanical arm 2, because the other end of the spring fixedly connected with the bottom of the long plate 111 is connected with the mechanical arm 2, when grabbing a heavy workpiece, the knob 131 is rotated clockwise, the knob 131 drives the second round rod 121 to rotate clockwise, because the spring is designed around the second round rod 121, in the process of rotating the second round rod 121, the adjusting block 141 fixedly connected with the bottom of the round rod drives the spring to rotate clockwise, in the process, because the spring is wound and contracted, the elastic force of the spring is gradually increased, so as to increase the grabbing tension of the mechanical arm 2, when the tension of the mechanical arm 2 is appropriate, because the upper surface of the long plate 111 is connected with the clamping plate in a sliding way, the circular groove on the clamping plate is matched with the second round rod 121, thereby clamping the second round rod 121, because the opposite sides of the mechanical arm 2 are fixedly connected with the uniformly arranged circular rings 221, and the blocking rods 231 are hinged in the circular rings 221 through rotating shafts, the pull ring on the other side of the spring can be hung on the stop lever 231 in the circular ring 221, when the pull ring is hung on the stop lever 231 in the circular ring 221, the stop lever is pressed downwards through the pull ring, because the stop lever 231 is fixed in the circular ring 221 through the rotating shaft, the stop lever 231 rotates downwards when the pull ring is pressed, the pull ring slides downwards to the bottom of the stop lever 231 along the stop lever 231, the stop lever 231 is restored to the initial position under the acting force of the spring, when the pull ring is clamped in the stop lever 231, because the inner walls on the two opposite sides of the notch of the circular ring 221 are connected through the elastic cloth 241, the pull ring drives the elastic cloth 241 to move towards the circular ring 221 together, and meanwhile, the pull ring is arranged at the bottom of the stop lever 231 under the action of the elastic.
