[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment:

[0026] A composite nut, such as Figures 1-5 As shown, it includes an outer nut 1 and an inner nut 5. The outer nut 1 has a rotating groove 2 inside, and the inner nut 5 is provided on the inner side of the outer nut 1. A rotating block 6 is fixed on the outer side of the inner nut 5, and rotating rings 7 are fixed at both ends of the rotating block 6, which are engaged with the rotating groove 2 and rotate. Two sets of insert blocks 9 are fixed on the outer side of the inner nut 5 and below the rotating block 6. Several sets of insertion holes 10 are opened at equal intervals inside the two sets of insert blocks 9. Pressing strips 11 are slidably provided on both sides of the outer nut 1. A fixing plate 14 is fixed at one end of the pressing strip 11 near the vertical central axis of the outer nut 1, and several sets of connecting bolts 15 are fixed at equal intervals at the other end of the fixing plate 14, which are arranged in a corresponding manner to the several sets of insertion holes 10 and are engaged with each other.

[0027] The rotating clamping groove 2 is arranged in the outer nut 1, the rotating clamping block 6 and the rotating clamping ring 7 are fixed outside the inner nut 5, so that the inner nut 5 can rotate freely in the outer nut 1 and is clamped with the rotating clamping groove 2, so that when the outer nut 1 is accidentally touched, the fastening connection of the inner nut 5 and the bolt is not affected, the stability and anti-interference ability of the nut are effectively improved, the plug 9 and the insertion hole 10 are arranged outside the inner nut 5, the pressing strip 11, the fixed plate 14 and the connecting bolt 15 are arranged on both sides of the outer nut 1, the connecting bolt 15 is inserted and clamped with the insertion hole 10 by pressing the pressing strip 11, and then the outer nut 1 drives the inner nut 5 to rotate synchronously to release the threaded connection. This design is convenient to operate, and enhances the flexibility and practicality of the nut.

[0028] Referring to Figure 3 and Figure 4 , the two groups of limiting sliding rods 3 are symmetrically arranged on both sides of the inner part of the outer nut 1, and the outer side of the limiting sliding rod 3 is sleeved with the spring 4;

[0029] Among them, two groups of limiting sliding rods 3 are symmetrically arranged on both sides of the inner part of the outer nut 1, which can provide clear guidance for the sliding block 13 during movement, so that the movement of the sliding block 13 in the outer nut 1 is more stable and smooth, and the unstable connection problem caused by shaking or deviation is reduced. When the sliding block 13 is subjected to external force, the spring 4 can absorb part of the energy to prevent the sliding block 13 from being damaged due to excessive impact. When the external force disappears, the spring 4 can push the sliding block 13 back to the appropriate position.

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , the inner nut 5 is internally provided with a thread 8 and is threadedly connected with the bolt;

[0031] Among them, the inner nut 5 is internally provided with a thread 8 and is threadedly connected with the bolt. This standard threaded connection method has the characteristics of tight connection and strong bearing capacity, and can form a stable connection between the inner nut 5 and the bolt.

[0032] Referring to Figure 2 and Figure 3 , the pressing plate 12 is fixed to the end of the pressing strip 11 away from the outer nut 1, and the sliding block 13 is fixed to both sides of the pressing strip 11 and is limited to slide with the spring 4;

[0033] Among them, the pressing plate 12 is fixed to the end of the pressing strip 11 away from the outer nut 1. This design increases the contact area between the operator and the pressing strip 11, making it more convenient and labor-saving for the operator to press, improving the convenience and comfort of operation, and reducing the difficulty of operation. The elastic effect of the spring 4 can make the pressing strip 11 automatically rebound to the initial position after pressing, preparing for the next operation, improving the use efficiency and reliability of the device.

[0034] Referring to Figure 3 and Figure 4 Two ends of the spring 4 are respectively abutted tightly with the sliding block 13 and the outer nut 1;

[0035] When the pressing plate 12 is pressed to drive the pressing strip 11 to slide, the elastic force of the spring 4 can ensure the smooth movement of the pressing strip 11, and after the pressing is finished, the pressing strip 11 can be quickly pushed back to the original position, so that the device can be restored to the initial state in time, and the operation fluency is improved.

[0036] The implementation principle of the embodiment is as follows: first, when the outer nut 1 needs to be installed, the pressing plate 12 on both sides of the outer nut 1 is pressed to drive the pressing strip 11 to slide, so that the sliding block 13 drives the connecting bolt 15 on the fixed plate 14 to be inserted and clamped with the insertion hole 10 on the insertion block 9, so that when the outer nut 1 is rotated, the inner nut 5 inside the outer nut 1 can be driven to rotate synchronously, so that the screw thread 8 in the inner nut 5 is screwed and fastened with the bolt, then when the outer nut 1 is installed, the pressing plate 12 can be released, the sliding block 13 can be compressed and elastically released by the spring 4, so that the sliding block 13 slides along the outside of the limiting sliding rod 3, so that the sliding block 13 returns the pressing plate 12 to the original position through the pressing strip 11, and finally when the inner nut 5 is fastened with the bolt, the outer nut 1 is not affected by the fastening of the rotating clamping groove 2 through the rotating clamping block 6 on the outside and the rotating clamping ring 7 at both ends of the rotating clamping block 6.
