[0043] The following section will explain the specific settings and functions of the replacement device 6, the telescopic device 7, and the limiting device 8.

[0044] like Figures 1-6As shown, the replacement device 6 also includes a mounting block 605 fixedly connected to the inner wall of the handle 5. A sleeve plate 604 is rotatably connected to the upper surface of the mounting block 605, and a rotating plate 603 is slidably connected to the inner wall of the sleeve plate 604. The rotating plate 603 is rotatably connected to the push block 601. By setting the mounting block 605, the sleeve plate 604 and the rotating plate 603 can be installed. By setting the sleeve plate 604 and the rotating plate 603, the rotation of the push block 601 can be restricted during its movement. A limit block 610 is fixedly connected to the surface of the slide plate 608, and a pull plate 609 is fixedly connected to one end of the slide plate 608 near the connecting block 607. By setting the limit block 610, the position of the slide plate 608 can be restricted. By setting the pull plate 609, the position of the slide plate 608 can be easily moved.

[0045] A connecting plate 611 is fixedly connected to the side of the slide plate 608 near the leaf spring 4. An adjusting screw 612 is threaded into the inner wall of the connecting plate 611. By setting the connecting plate 611, the adjusting screw 612 can be connected to the slide plate 608. The adjusting screw 612, threaded into the inner wall of the connecting plate 611, can be adjusted in position by rotation. A clamping plate 613 is rotatably connected to the end of the adjusting screw 612 near the leaf spring 4. A limiting rod 614 is fixedly connected to the side of the clamping plate 613 near the connecting plate 611. The limiting rod 614 is slidably connected to the inner wall of the connecting plate 611. By setting the adjusting screw 612, the position of the clamping plate 613 can be easily adjusted. The adjusting screw 612, rotatably connected to the clamping plate 613, can adjust the position of the clamping plate 613 without causing the clamping plate 613 to rotate. The limiting rod 614 prevents the clamping plate 613 from rotating.

[0046] like Figure 1 and Figure 2 as well as Figure 6 and Figure 7 As shown, the telescopic device 7 also includes a second fixing plate 706 fixedly connected to the surface of the handle 5, a second arc-shaped plate 708 fixedly connected to the surface of the connecting rod 701, and a positioning rod 710 fixedly connected to the side of the second fixing plate 706 near the connecting rod 701. The positioning rod 710 is slidably connected to the inner wall of the second arc-shaped plate 708. By setting the second fixing plate 706, the positioning rod 710 can be connected to the handle 5. By setting the positioning rod 710 and the second arc-shaped plate 708, a positioning effect can be achieved during the connection of the handle 5 and the connecting rod 701.

[0047] A first fixing plate 705 is fixedly connected to the surface of the handle 5, and a first arc-shaped plate 707 is fixedly connected to the surface of the connecting rod 701. A connecting screw 709 is threaded into the inner walls of the first fixing plate 705 and the first arc-shaped plate 707. By setting the first fixing plate 705, the connecting screw 709 can be connected to the handle 5. The stability of the connection between the handle 5 and the connecting rod 701 can be ensured as much as possible by setting the first fixing plate 705, the first arc-shaped plate 707, and the connecting screw 709. A limiting ring 704 is fixedly connected to the surface of the connecting rod 701, and the limiting ring 704 is slidably connected to the inner wall of the adjusting cylinder 703. The limiting ring 704, slidably connected to the inner wall of the adjusting cylinder 703, does not affect the rotation of the connecting rod 701. By setting the limiting ring 704, the stability of the connecting rod 701's rotation inside the adjusting cylinder 703 can be ensured.

[0048] like Figure 2 and Figures 8-10 As shown, the limiting device 8 also includes two locking plates 84 fixedly connected to the upper surface of the support plate 83, and a stop rod 85 is fixedly connected to the side of the two locking plates 84 near the leaf spring 4. By setting the locking plates 84 and the stop rod 85, the effect of limiting the position of the leaf spring 4 can be improved, and the stability of the leaf spring 4 during the installation process can be improved.

[0049] A fixing rod 86 is fixedly connected to the inner wall of the slider 82. The fixing rod 86 is fixedly connected to the surface of the groove on the handle 5. A spring 87 is sleeved on the surface of the fixing rod 86, and both ends of the spring 87 are fixedly connected to the slider 82 and the handle 5, respectively. By setting the fixing rod 86, the position of the spring 87 can be restricted. By setting the spring 87, the movement of the slider 82 can be assisted. By setting the fixing rod 86 and the spring 87, the smoothness of the slider 82's movement can be improved.

[0050] Working principle: Before using the grooved precision casting module hook, it needs to be assembled. The handle 5 and the module body 1 are connected by the connecting tube 2, and the positions of the connecting tube 2 and the module body 1 are fixed by the leaf spring 4 and the hook body 3. When the leaf spring 4 needs to be replaced, rotate the push screw 602 to make it rotate on the inner wall of the handle 5. At this time, the push screw 602 rotates on the surface of the push block 601, causing the push block 601 to drive the rotating plate 603 to rotate. At the same time, the rotating plate 603 slides on the inner wall of the sleeve plate 604, causing the sleeve plate 604 to rotate on the surface of the mounting block 605. The movement of the push block 601 causes the leaf spring 4 to retract, thereby releasing the restriction on the position of the leaf spring 4 on the hook body 3. Then, pull the slide plate 609 to slide the slide plate 608 on the inner wall of the connecting block 607, causing the slide plate 608 to drive the leaf spring 4 to move away from the hook body 3. Then, rotate the adjusting screw 612 to make it rotate on the inner wall of the connecting plate 611. At this time, the limiting rod 614 slides on the inner wall of the connecting plate 611 and the clamping plate 613 moves. Move the leaf spring 4 away from the slide plate 608, and move the leaf spring 4 to be installed closer to the slide plate 608. Rotate the adjusting screw 612 so that the clamping plate 613 restricts the position of the leaf spring 4. Move the slide plate 608 so that the leaf spring 4 moves away from the fixing ring 606. When the leaf spring 4 is inserted into the hook body 3, the limiting block 610 abuts against the connecting block 607, completing the replacement of the leaf spring 4. By setting the replacement device 6, the leaf spring 4 in the grooved precision casting module hook can be easily replaced after fatigue, which improves the efficiency of replacing the leaf spring 4, reduces the complexity of maintaining the grooved precision casting module hook, and at the same time ensures the service life of the grooved precision casting module hook as much as possible.

[0051] When the length of handle 5 needs to be adjusted, first move connecting rod 701 close to handle 5 so that positioning rod 710 on second fixed plate 706 is engaged in second arc plate 708. Then rotate connecting screw 709 to make it rotate on the inner wall of first fixed plate 705, thereby connecting first fixed plate 705 and first arc plate 707 and completing the installation of connecting rod 701. Then rotate adjusting cylinder 703 to drive threaded ring 702 to rotate on the surface of connecting rod 701, thereby completing the length adjustment. By setting limit ring 704, the stability during length adjustment can be improved. By setting telescopic device 7, the length of grooved precision casting module hook can be adjusted, thereby maximizing the flexibility of using grooved precision casting module hook and improving the convenience of using grooved precision casting module hook.

[0052] When replacing the leaf spring 4, pull the slide plate 608 to move the leaf spring 4 away from the module body 1, remove the leaf spring 4, grasp the support plate 83, and move the leaf spring 4 to be installed into the space between the support plate 83 and the abutment rod 85. At this time, the support plate 83, the abutment rod 85, and the clamping plate 84 can restrict the position of the leaf spring 4. Then, control the leaf spring 4 to move into the space between the two limiting plates 81, and then move the leaf spring 4 closer to the hook body 3 through the slide plate 608. During this process, the slider 82 slides on the surface of the fixed rod 86, and the spring 87 extends, which facilitates the installation of the leaf spring 4. By setting the limiting device 8, the position of the leaf spring 4 can be restricted and positioned when replacing the leaf spring 4 of the grooved precision casting module hook, so as to facilitate the replacement operation of the leaf spring 4 as much as possible, reduce the difficulty of replacing the leaf spring 4, and improve the efficiency of the leaf spring 4 installation.
