[0035] Working principle: each second screw rod 48 is arranged along the circumferential circle of the bevel rack 43. When the bevel rack 43 and the arc rod 44 are connected by the connecting structure, they can rotate in the connecting block 41. At this time, the meshing bevel gear 47 can be driven to make the bevel gear 47 rotate. When the bevel gear 47 rotates, it will drive the second screw rod 48 to move, and the second screw rod 48 and the connecting block 41 are slidingly connected, so as to avoid the second screw rod 48 from rotating when it moves. At this time, each second screw rod 48 will move in the direction of approaching each other, so as to squeeze the cable, so as to install the connecting block 41 on the cable. After the arc rod 44 and the bevel rack 43 are separated, it will be convenient for the cable to enter between the second screw rods 48, and through the movement between the second screw rods 48, The connecting block 41 is installed on cables of different diameters, wherein the bevel rack 43 and the arc rod 44 form a ring and can be rotated in the connecting block 41, thereby driving each bevel gear 47 to rotate, and the bevel rack 43 and the arc rod 44 are both provided with a connecting groove 5, and the connecting block 41 limits the rotation of the bevel rack 43 and the arc rod 44 through the connecting groove 5, and when the bevel rack 43 and the arc rod 44 are rotated to a suitable position, the second screw 42 is tightened, and the second screw 42 will squeeze the bevel rack 43 or the arc rod 44, thereby limiting the bevel rack 43 or the arc rod 44 to prevent the two from moving, thereby ensuring that the bevel gear 47 meshing with the bevel rack 43 and the arc rod 44 will not rotate, wherein when the second screw 48 moves, it will drive the pressing plate 4 9 is moved, wherein the second screw rods 48 are preferably three, and at this time the three second screw rods 48 will move toward the center of the circle, and the cable will also be placed at the center of the circle, and at this time the three pressure plates 49 will clamp the cable under the drive of the three second screw rods 48, and the friction between the pressure plates 49 and the cable will be increased by the rubber pad, and after the bevel rack 43 and the arc rod 44 are docked, the sliding plug rod 45 is inserted into the slot 431, and at this time the bevel rack 43 will be connected to the arc rod 44 to form a circle, wherein the plug rod 45 will not extend into the connecting groove 5, thereby preventing the plug rod 45 from affecting the rotation of the bevel rack 43 and the arc rod 44, and the spring 46 will always push the plug rod 45 to be inserted into the slot 431, avoiding the arc rod 44 and the bevel rack 43 The "L"-shaped plug rod 45 is convenient for the staff to use, and it is convenient to slide it out of the slot 431 or insert it into the slot 431. When the anti-vibration hammer needs to be installed on a cable with a larger size, the weight of the hammer body is often required to be greater. At this time, the first screw rod 34 is rotated first. At this time, the first screw rod 34 will drive the second hammer body 36 to move in a direction away from the first hammer body 31. At this time, a storage space will be generated between the first hammer body 31 and the second hammer body 36. During the rotation of the first screw rod 34, the limit rod 35 on the second hammer body 36 is always inserted in the first hammer body 31 to ensure that the second hammer body 36 will not rotate during the movement. Then the spare block 37 can be put on the limit rod 35. At this time, the spare block 37 will be placed in the storage space.By adding different numbers of spare blocks 37 as needed, when the spare blocks 37 are added, the first screw rod 34 is screwed, and the first screw rod 34 will drive the second hammer body 36 to move toward the direction of the first hammer body 31, so that the first hammer body 31 and the second hammer body 36 clamp the spare block 37 to prevent the spare block 37 from falling off. The limiting rod 35 is specifically square. When the spare block 37 is sleeved on the limiting rod 35 through the groove 371, the groove 371 and the square limiting rod 35 are closely matched, so as to prevent the spare block 37 from being offset. The spare block 37 is installed in the limiting rod 35. After the positioning rod 35 is positioned, the sleeve 32 is slid until the sleeve 32 blocks the storage space. At this time, the two first screws 33 are respectively located on the first hammer body 31 and the second hammer body 36. Then the two first screws 33 are tightened. At this time, the two first screws 33 are respectively against the first hammer body 31 and the second hammer body 36, thereby limiting the movement of the sleeve 32. The sleeve 32 also ensures that no debris falls into the storage space. The two first screws 33 on the sleeve 32 also further limit the second hammer body 36 to prevent the second hammer body 36 from sliding.
