[0027] like Figure 1-Figure 4 As shown, the present embodiment provides an assembly structure of a handle for connecting a handle body 10 and a hollow rod body 30, wherein the assembly structure of the handle includes a first locking portion 20, wherein the handle body 10 and the first locking portion 20 can be connected or separated by axial movement, wherein the first locking portion 20 includes an expansion body 21 and a linkage shaft 22, wherein the expansion body 21 is axially penetrated with a through hole, wherein the linkage shaft 22 can penetrate into the expansion body 21 along the through hole under the action of an external force, and wherein the expansion body 21 can deform and expand in a radial direction after the linkage shaft 22 penetrates.

[0028] The expansion body 21 is provided with a deformation groove 201 , which is communicated with the through hole. After the linkage shaft 22 penetrates into the expansion body 21 , the deformation groove 201 has a tendency to expand.

[0029] Moreover, the expansion body 21 includes a first expansion unit 211 and a second expansion unit 212, and the deformation groove 201 axially penetrates the first expansion unit 211 and the second expansion unit 212. The first expansion unit 211 is for the linkage shaft 22 to penetrate, and the second expansion unit 212 is for the handle body 10 to penetrate. One end of the handle body 10 has a locking head 11, and the locking head 11 is plugged into the second expansion unit 212.

[0030] A circle of positioning grooves 111 is arranged around the locking head 11 , and a positioning protrusion 213 is arranged around the inner wall of the second expansion unit 212 . The positioning protrusion 213 is engaged with the positioning grooves 111 .

[0031] Moreover, the linkage shaft body 22 includes an end portion 221 and a shaft portion 222 which are coaxially arranged. The outer diameter of the end portion 221 is larger than the outer diameter of the shaft portion 222. The shaft portion 222 is used to penetrate the first expansion unit 211. The outer peripheral surface of the end portion 221 is in contact with the inner side surface of the hollow rod body 30.

[0032] Furthermore, the second locking portion 20 is arranged in the hollow rod body 30, and the linkage shaft body 22 can move along the axial direction of the hollow rod body 30 and penetrate into the expansion body 21 under the action of external force. After the linkage shaft body 22 penetrates, the expansion body 21 can expand to abut against the inner wall of the hollow rod body 30, and thus be fixed at any position of the hollow rod body 30.

[0033] Meanwhile, a pushing rod 40 is also included, and the pushing rod 40 is used to push the linkage shaft 22 into the expansion body 21 .

[0034] Here, the expansion body 21 and the linkage shaft body 22 are integrally formed, and a connecting rib 23 is provided between the expansion body 21 and the linkage shaft body 22 . The expansion body 21 can be separated from the connecting rib 23 to the inside of the expansion body 21 under the action of external force.

[0035] When assembling the utility model, the first locking portion 20 is first pushed into the hollow rod body 30 through a push plate 50, and then the push plate 50 is kept stationary, and the push rod 40 is then inserted from the other end of the hollow rod body 30 until it contacts the end 221 of the linkage shaft body 22, and force is continued until the connecting rib 23 is broken, and then the shaft portion 222 of the linkage shaft body 22 is inserted into the first expansion unit 211 of the expansion body 21 to achieve an interference fit, and the first expansion unit 211 expands outward until it abuts against the inner wall of the hollow rod body 30, thereby the second locking portion 20 is fixed at this position and cannot continue to move, and then the handle body 10 is inserted into the second expansion unit 212 of the expansion body 21 until the positioning protrusion 213 is engaged with the positioning groove 111 to achieve connection.

[0036] Example 2

[0037] like Figure 5 As shown, in this embodiment, the expansion body 21 and the linkage shaft body 22 are split structures. During assembly, the linkage shaft body 22 is first pre-pressed into the expansion body 21, but not completely pressed in, and then the first locking portion 20 is pushed into the hollow rod body 30 through a push plate 50. Subsequently, the push plate 50 is kept stationary, and the push rod 40 is inserted from the other end of the hollow rod body 30 until it contacts the end 221 of the linkage shaft body 22. Force is continued to be applied until the shaft portion 222 of the linkage shaft body 22 is inserted into the first expansion unit 211 of the expansion body 21 to achieve an interference fit. The first expansion unit 211 expands outward until it abuts against the inner wall of the hollow rod body 30, thereby the second locking portion 20 is fixed in this position and cannot continue to move. Then the handle body 10 is inserted into the second expansion unit 212 of the expansion body 21 until the positioning protrusion 213 is engaged with the positioning groove 111 to achieve connection.
