The clamping plate 14 can be moved by rotating the screw rod 13, and the first telescopic rod 15 will perform a telescopic movement to make the clamping plates 14 on both sides approach the middle, and then move the mold body 1 to the middle of the clamping plates 14 on both sides, so that the positioning rod 18 is aligned with the bracket 16. At this time, under the action of the magnetic attraction between the magnetic block 19 and the magnetic ring 110, the positioning rod 18 can be moved to the middle of the first through hole 17, and then the positioning rod 18 is passed through the side wall of the first through hole 17, and the mold body 1 is positioned by the positioning rod 18. After that, the screw rod 13 is held and rotated again, and the mold body 1 is clamped and fixed by the clamping plate 14. In this process, the existing difficulty in positioning the mold body 1 can be reduced, resulting in a more cumbersome installation process, which has a certain impact on the production speed of the hook. At this time, the positioning rod 18 is inserted into the side wall of the first through hole 17 to position the mold body 1, and the clamping plate 14 can play a role in fixing and clamping the mold body 1 during processing.

When the fixing plate 36 is fully inserted into the inner wall of the fixing block 3, the slot 37 will correspond to the position of the insert block 34. At this time, by loosening the pull rod 35, a certain reaction force will be applied to the insert block 34 under the elastic action of the first spring 33, so that the insert block 34 passes through the second through hole 31 and is inserted into the side wall of the slot 37, so that the vertical plate 12 can be fixed. In this process, the screw rod 13 can be reduced from being damaged during long-term use, which makes it inconvenient to disassemble and replace it, thereby increasing a certain amount of workload. At this time, the fixed block 3 is set to facilitate the disassembly and maintenance of the screw 13.

[0026] like Figure 3 As shown, the side wall of the bracket 16 is provided with a pair of limit blocks 4; the limit blocks 4 are symmetrically arranged on both sides of the bracket 16 and have the same structure; the side walls of the limit blocks 4 are evenly fixed with a plurality of arc plates 41; when in use, first align the positioning rod 18 with the first through hole 17, and then insert the positioning rod 18 into the side wall of the first through hole 17, at this time, the positioning rod 18 will contact the limit blocks 4 on both sides, and under the tilting action of the limit blocks 4, the positioning rod 18 will slide toward the middle of the limit blocks 4 on both sides, and at the same time, when the positioning rod 18 slides to To a certain extent, the arc-shaped action of the arc plate 41 can block the positioning rod 18 to reduce the sliding of the positioning rod 18 toward the outside. In this process, it can reduce the difficulty in aligning the positioning rod 18 with the first through hole 17 when the positioning rod 18 is inserted into the side wall of the first through hole 17, thereby causing the insertion process to be more cumbersome. At this time, the limit block 4 is set to play a limiting role when the positioning rod 18 is inserted into the side wall of the first through hole 17, and at the same time, the arc plate 41 can prevent the positioning rod 18 from falling off.

[0027] like Figure 3As shown, a pair of second telescopic rods 5 are fixedly connected to the side wall of the bracket 16; the second telescopic rods 5 are symmetrically arranged on both sides of the bracket 16 and have the same structure; a second spring 51 is sleeved on the outer side of the second telescopic rod 5; the second telescopic rod 5, the second spring 51 and the limit block 4 are in a fixed relationship; when in use, when the positioning rod 18 is inserted into the side wall of the first through hole 17, due to the squeezing of the limit blocks 4 on both sides, the second telescopic rod 5 and the second spring 51 can perform telescopic movement, and at this time, under the elastic action of the second spring 51, the limit blocks can be 4 exerts a certain reaction force. At this time, the positioning rod 18 can be pushed to the middle of the first through hole 17 through the limit blocks 4 on both sides. In this process, the positioning rod 18 can be inserted into the side wall of the first through hole 17. In the process, the positioning rod 18 is easily hit against the wall of the limit block 4, which makes it difficult to move the limit block 4, thereby making the insertion process more complicated. At this time, the second telescopic rod 5 and the second spring 51 are set to further increase the limiting effect when the positioning rod 18 is inserted into the side wall of the first through hole 17.

[0028] like Figure 4 As shown, a pair of protrusions 6 are symmetrically fixed to the inner side wall of the fixing block 3; a pair of rubber blocks 61 are symmetrically fixed to the side wall of the fixing plate 36; when in use, by pressing the fixing plate 36 into the fixing block 3, the rubber block 61 will shrink due to the squeezing of the protrusions 6. When the fixing plate 36 is completely pressed into the fixing block 3, the protrusions 6 will be staggered from the rubber blocks 61. At this time, under the elastic action of the rubber blocks 61, they can quickly recover and get stuck to fix the fixing plate 36. In this process, the vertical plate 12 can be reduced from accidentally pulling the pull rod 35 during use, causing the insert block 34 to slide out from the side wall of the slot 37, thereby causing a certain impact on the fixing effect of the vertical plate 12. At this time, the protrusions 6 and rubber blocks 61 are set to further increase the fixing effect of the vertical plate 12 after installation.

[0029] like Figure 2 As shown, the side wall of the clamp 14 is evenly fixed with a plurality of rubber strips 7; when in use, when the clamp 14 clamps and fixes the mold body 1, the rubber strips 7 can be fully fitted with the side wall of the mold body 1 under the mutual squeezing of the clamp 14 and the mold body 1, thereby generating a certain friction force. In this process, the friction force between the clamp 14 and the mold body 1 can be reduced, resulting in the mold body 1 being easy to slide on the side wall of the clamp 14 when accidentally hitting the mold body 1. At this time, the rubber strips 7 are provided to increase the fixing effect between the mold body 1 and the clamp 14.

[0030] During operation, the staff first holds the screw 13 and rotates it. By rotating the screw 13, the clamping plate 14 can be moved, and the first telescopic rod 15 will perform a telescopic movement to make the clamping plates 14 on both sides approach the middle. Then, the mold body 1 is moved to the middle of the clamping plates 14 on both sides, so that the positioning rod 18 is aligned with the bracket 16. At this time, under the effect of the magnetic attraction between the magnetic block 19 and the magnetic ring 110, the positioning rod 18 can be moved to the middle of the first through hole 17, and then the positioning rod 18 passes through the side wall of the first through hole 17. The mold body 1 is positioned by the positioning rod 18, and then the screw 13 is held and rotated again, and the mold body 1 is clamped and fixed by the clamping plate 14. When in use, first adjust the clamping plate 14 to a suitable position, and then place the mold body 1 on both sides. The clamping plate 14 is in the middle of the clamping plates 14. At this time, the side wall of the mold body 1 will contact the cleaning brush 21. The cleaning brush 21 can be used to clean the side wall of the mold body 1, and the dust and impurities attached to the side wall of the mold body 1 can be swept away, so that the clamping plate 14 can be fully in contact with the side wall of the mold body 1. At the same time, the connecting rod 22 can be used to fix and connect them when the cleaning brush 21 is cleaning, so that they are concentrated together when cleaning. When the mold body 1 is placed in the middle of the clamping plates 14 on both sides, the mold body 1 will squeeze the elastic sheet 23, and the elastic sheet 23 can be deformed by squeezing it. When the mold body 1 is staggered with the elastic sheet 23, it will automatically recover and swing under the elastic action of the elastic sheet 23. The vibration generated by the swing can The dust and impurities on the surface are shaken off. When in use, the staff first holds and pulls the pull rod 35, and pulls the plug block 34 to one side of the pull rod 35. At this time, the first spring 33 is squeezed and will perform a telescopic movement. Then, by holding the vertical plate 12, the fixing plate 36 is inserted into the inner wall of the fixing block 3. When the fixing plate 36 is fully inserted into the inner wall of the fixing block 3, the slot 37 will correspond to the position of the plug block 34. At this time, by loosening the pull rod 35, a certain reaction force will be applied to the plug block 34 under the elastic action of the first spring 33, so that the plug block 34 passes through the second through hole 31 and is inserted into the side wall of the slot 37, so that the vertical plate 12 can be fixed. When in use, first align the positioning rod 18 with the first through hole 17, and then insert the positioning rod 18 into On the side wall of the first through hole 17, the positioning rod 18 will contact the limit blocks 4 on both sides. Under the inclination of the limit blocks 4, the positioning rod 18 will slide toward the middle of the limit blocks 4 on both sides. At the same time, when the positioning rod 18 slides to a certain extent, the arc-shaped action of the arc plate 41 can block the positioning rod 18 to reduce the sliding of the positioning rod 18 to the outside. In use, when the positioning rod 18 is inserted into the side wall of the first through hole 17, due to the squeezing of the limit blocks 4 on both sides, the second telescopic rod 5 and the second spring 51 can be telescopically moved. At this time, under the elastic action of the second spring 51, a certain reaction force can be applied to the squeezing force generated by the limit blocks 4. At this time, the positioning rod 18 can be pushed toward the middle of the first through hole 17 through the limit blocks 4 on both sides. In use,When the fixing plate 36 is pressed into the fixing block 3, the rubber block 61 is squeezed by the protrusion 6 and shrinks. When the fixing plate 36 is completely pressed into the fixing block 3, the protrusion 6 will be offset from the rubber block 61. At this time, under the elastic effect of the rubber block 61, it can quickly recover and get stuck to fix the fixing plate 36. When in use, when the clamping plate 14 clamps and fixes the mold body 1, under the mutual squeezing of the clamping plate 14 and the mold body 1, the rubber strip 7 can be fully fitted with the side wall of the mold body 1, thereby generating a certain friction force.
