Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a connector includes a tube body 10, which is a hollow structure. A gasket 13 is fixed to one end of the tube body 10, and a connector head 12 is fixed to the other end of the gasket 13. The connector head 12 is elastic and capable of elastic deformation. The outer periphery of the connector head 12 is round, and the inner periphery is a regular hexagon. The connector head 12 has several deformation grooves 27. Preferably, as shown... Figure 4 As shown, in this embodiment, four deformation grooves 27 are provided, and a locking head 16 is threadedly connected to the outer circumference of the connector 12. After the locking head 16 is screwed in, it fixes the shaft that extends from one end of the tube body 10 into the tube body 10. After the locking head 16 is screwed in, the connector 12 will deform. A connecting cavity 14 is provided through the tube body 10. In this embodiment, the cross-section of the connecting cavity 14 is a regular hexagon.

[0024] like Figure 1 and Figure 3As shown, the number of connecting heads 12 is greater than or equal to 2, and the deformation groove 27 is arranged symmetrically with respect to the center of the cross section of the pipe body 10.

[0025] As shown in Figure 1 and Figure 6 , the connecting head 12 is composed of a first stress section 25, a bending section 24 and a second stress section 23 connected in sequence, the first stress section 25 is fixed at one end of the gasket 13, the bending section 24 is deformed under the action of the locking head 16, the bending section 24 drives the second stress section 23 to approach each other, thereby realizing the fixation of the shaft, the outer periphery of the first stress section 25 is provided with external threads 22, the connecting head 12 is fixedly provided with a sleeve head 26, the first installation cavity 19 is provided in the sleeve head 26, the first installation cavity 19 is provided with internal threads 20, the internal threads 20 are matched with the external threads 22, so that the locking head 16 is threadedly connected with the connecting head 12.

[0026] The first installation cavity 19 is provided with a second installation cavity 18 which is communicated with the outside, and the second stress section 23 extends into the second installation cavity 18 after the locking head 16 is screwed in.
