At present, with the continuous growth of the demand for communication products, higher and higher requirements are put forward for the production capacity of equipment manufacturers, and at the same time, the requirements for the cost, weight and reliability of communication products are also more and more stringent. In order to facilitate the positioning of the equipment, pins are often used to complete the equipment, and a certain cost is incurred for its manufacture and assembly. In the past, such parts have been assembled in the form of threads. In order to ensure that the assembly height is within the specified range and to prevent loosening, bar turning is often used to form threads and positioning steps, and thread pinning glue is used in the assembly, and the cost of machining is relatively high. Large, more material waste. Based on the above drawbacks, in order to better solve this problem, some existing manufacturers use the interference fit riveting method, which solves the problem of material waste and anti-loosening, but the inner diameter of the pin hole and the outer diameter of the pin are matched. The machining accuracy of the machine is relatively high. Once the matching size is out of tolerance, a second matching is required, which wastes working hours and increases the slack time.

It can be seen from the figure that no matter how the screw core swings, it will not fall off from the screw sleeve. This is because part of the bead 5 is stuck in the hole 6 of the screw sleeve 1 and the other part is stuck in the screw core 2. In the groove 8, it plays the role of positioning. If the screw sleeve rotates clockwise, the beads 5 can only slide in the groove 8 of the screw core 2 under the driving of the screw sleeve 1 and cannot drive the screw core 2 to rotate. If the screw sleeve 8 rotates in the opposite direction, the bead 5 will be stuck on the stop 7 of the screw core 2 so as to drive the screw core 2 to rotate.

Tightening nut

In order to meet the needs of different assembled installation components, there are also hand-tightening methods for tightening the screws, but in actual use, ordinary manual screws can easily cause hand pain to the user, and the operation is extremely inconvenient; at the same time, due to tightening The contact area between the screw and the installation component is too small. If the user exerts too much force, the uneven force per unit area of the installation component will cause deformation and depression, which will affect the use. Therefore, a manual screw is proposed to solve the above problems.

In view of the deficiencies of the prior art, Guangdong Yueluo Hardware Industry Co., Ltd. provides a relatively simple screw that can be manually disassembled. In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical scheme: a screw that can be disassembled manually, including a stud and a nut, and the axial direction of the screw is provided with a screw extending from the nut to the stud. A groove, a control column that is slidably matched with the groove is arranged in the groove, a through groove is opened on the circumferential side wall of the control column, and a circumferential side wall of the control column is provided with a parallel to the axis of the control column. A limit bar, the side wall of the groove is provided with a limit groove that cooperates with the limit bar, the control column is provided with a accommodating groove, and the accommodating groove is provided with a rotating rod that cooperates with the through groove, so The accommodating groove and the rotating rod are arranged separately. Further, a accommodating groove is opened at the corresponding groove on the nut, a baffle is hinged on the side wall of the accommodating groove, and a torsion spring is provided at the hinged joint between the baffle and the accommodating groove.
