[0027] When it is necessary to adjust the direction and position of the wire clamping mechanism 4 and the circular ring clamping mechanism 3 and to disassemble them, the nut 35 is rotated to the right from the outer wall of the screw 2 33, so that the outer wall of the cylinder 2 37 and the upper and lower sides of the inner wall of the square groove are rotated, so that the left and right semicircular rings 31 are rotated toward the sides away from each other and loosened. After adjusting to the required direction and position, the nut 35 is rotated on the outer wall of the screw 2 33 to squeeze the sides away from each other of the left and right fixing blocks 32 to fix them, so that the direction and position can be flexibly adjusted when clamping the wire, and the nut 35 can be disassembled after it is completely turned out from the outer wall of the screw 2 33.

[0028] By pressing the button assembly 47, the clamping mechanism 4 can be rotated to an angle to facilitate clamping the line.

After sliding with the inner wall of the circular hole 482 and disengaging from the circular hole 482, the square block 41 is rotated to make the circular hole 482 slide. After the column plate 483 drives the outer wall of the circular wheel 481 and the inner wall of the circular groove 38 to rotate and adjust to the desired position, release the button 479, so that the spring 478 bounces the cylinder four 472 into the inner wall of the circular hole 482 for fixation. Finally, after placing the wire between the two wire clamping blocks 42, move the wire clamping block 42 to make the cylinder three 49 and the block two 46 slide, and then rotate the nut two 45 on the outer wall of the screw three 44 to squeeze the side away from the fixing block two 43 to fix the wire, making it more convenient and flexible to clamp the wire, so as to adapt to different work scenarios and wiring requirements.

[0029] Working principle: When the length of the cylinder 2 and the cylindrical tube mechanism 1 needs to be adjusted, the cylinder 21 is rotated upward to rotate the outer wall of the thread tooth 22 and the inner wall of the thread groove 1. After the screw is rotated out to the required length, the screw 13 is inserted into the threaded hole 12 and rotated until the thread gap with the thread tooth 22 is close.

[0030] The ring clamp mechanism 3 can be adjusted in direction and position and can be disassembled conveniently. When in use, the nut 35 is rotated to the right from the outer wall of the screw 2 33, so that the outer wall of the cylinder 2 37 and the upper and lower sides of the inner wall of the square groove are rotated, so that the left and right semicircular rings 31 are rotated toward the sides away from each other and then loosened. After adjusting to the desired direction and position, the nut 35 is rotated on the outer wall of the screw 2 33 to squeeze the sides of the left and right fixing blocks 32 away from each other to fix them, so that the direction and position can be flexibly adjusted when clamping the line. The nut 35 can also be disassembled after it is completely turned out from the outer wall of the screw 2 33.

[0031] By pressing the button assembly 47, the clamping mechanism 4 can be rotated to an angle to facilitate clamping the line. When in use, by pressing the button 479, the outer wall of the cylinder 5 473 slides with the inner wall of the cylindrical shell 471, and the semicircular ball 475 pulls the rope 476 through the cylindrical rod 477, so that the other end of the rope 476 pulls the cylinder 472, so that the outer wall of the cylinder 472 slides with the inside of the cylindrical shell 471, and then the spring 478 is squeezed. After sliding with the inner wall of the circular hole 482 and disengaging from the circular hole 482, the square block 41 is rotated to make the circular hole 482 slide. After the column plate 483 drives the outer wall of the circular wheel 481 and the inner wall of the circular groove 38 to rotate and adjust to the desired position, release the button 479, so that the spring 478 bounces the cylinder four 472 into the inner wall of the circular hole 482 for fixation. Finally, after placing the wire between the two wire clamping blocks 42, move the wire clamping block 42 to make the cylinder three 49 and the block two 46 slide, and then rotate the nut two 45 on the outer wall of the screw three 44 to squeeze the side away from the fixing block two 43 to fix the wire, making it more convenient and flexible to clamp the wire, so as to adapt to different work scenarios and wiring requirements.
