[0025] By utilizing the above technical solutions, this utility model not only achieves rapid positioning and stable connection, but also improves operating efficiency and equipment adaptability, making it suitable for various working conditions, reducing disassembly and assembly time, and extending equipment service life. With the cooperation of several limiting grooves 10 in the adjusting sleeve 4 and the positioning component 6, precise adjustment of the set screw length is achieved, meeting different usage requirements and avoiding the limitation of traditional integrated set screws having no adjustable length. Under the action of the positioning component 6, the adjusting sleeve 4 can be stably positioned during operation, preventing loosening or displacement and ensuring the stability of the set screw during use.
[0026] In one embodiment, for the threaded rod 5, the top of the threaded rod 5 is symmetrically provided with sliding grooves 501 that cooperate with two sets of positioning components 6, and the top of the sliding grooves 501 is provided with through grooves 502 that cooperate with the positioning components 6. Thus, under the combined action of the sliding grooves 501 and the through grooves 502, the stable operation of the positioning components 6 is ensured.
[0027] In one embodiment, the positioning component 6 includes a spring 601 disposed in the sliding groove 501. A limiting post 602 that cooperates with the limiting groove 10 is disposed on one side of the spring 601. A connecting rod 603 that cooperates with the through groove 502 is disposed at the top of the limiting post 602. A handle 604 is disposed on one side of the top of the connecting rod 603. An adjusting handle 605 is disposed at the end of the handle 604 away from the connecting rod 603. Thus, under the action of the positioning component 6, the adjusting sleeve 4 can be stably positioned during operation, avoiding loosening or displacement, and ensuring the stability of the set screw during use.
[0028] The working principle of the positioning component 6 is as follows: The operator holds the adjusting handle 605 and squeezes it inward. During the squeezing process, the connecting rod 603 moves inward through the grip rod 604. With the cooperation of the through groove 502, the limiting post 602 moves inward in the sliding groove 501 through the connecting rod 603. The limiting post 602 squeezes the spring 601. At this time, the adjusting sleeve 4 is put on the outside of the threaded rod 5 and aligned with the limiting groove 10 to be positioned according to the usage requirements. Then, the adjusting handle 605 is released. During the reset process of the spring 601, the spring 601 will squeeze the limiting post 602 outward in the sliding groove 501, causing the limiting post 602 to slide into the limiting groove 10 to be positioned.
[0029] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0030] In practical application, the operator holds the adjusting handle 605 of the positioning component 6 and squeezes it inward. During the squeezing process, the connecting rod 603 moves inward through the grip rod 604. With the cooperation of the through groove 502, the connecting rod 603 drives the limiting post 602 to move inward in the sliding groove 501, and the limiting post 602 squeezes the spring 601. At this time, the adjusting sleeve 4 is placed on the outside of the threaded rod 5 and aligned with the limiting groove 10 to be positioned according to the usage requirements. Then, the adjusting handle 605 is released. 5. During the reset process of spring 601, spring 601 will press the limiting post 602 outward in sliding groove 501, and make the limiting post 602 slide into the limiting groove 10 to be positioned (the working principle of positioning component 6 is as described above); at this time, under the action of anti-slip protrusion 8, hold the threaded base 1 and align the groove 2 at the bottom of the threaded base 1 with the adjusting sleeve 4. At this time, rotate the threaded base 1, and under the action of the internal thread of the adjusting sleeve 4 and the external thread in the groove 2, the connection between the threaded base 1 and the adjusting sleeve 4 is completed.
[0031] In summary, by utilizing the above-mentioned technical solutions of this utility model, this utility model not only achieves rapid positioning and stable connection, but also improves operating efficiency and equipment adaptability, making it suitable for various working conditions, reducing disassembly and assembly time, and extending equipment service life; under the cooperative action of several limiting grooves 10 in the adjusting sleeve 4 and the positioning component 6, the precise adjustment of the set screw length is achieved, meeting different usage requirements and avoiding the limitation of the traditional integrated set screw length not being adjustable; under the action of the positioning component 6, the adjusting sleeve 4 can be stably positioned during operation, avoiding loosening or displacement, and ensuring the stability of the set screw during use.
