The fixing member 250 is provided with a breakage preventing structure 259 engaged with a portion of the retractable electric wire 240, and the breakage preventing structure 259 is used for bending the portion of the retractable electric wire 240 to share the tensile force applied to the retractable electric wire 240. The anti-snap structure 259 provides an effective anti-snap effect, i.e., the retractable cord 240 is not easily pulled off or snapped by an installer when the handle assembly 200 is installed. The principle of the stretch-breaking prevention is that the stretchable electric wire 240 is not completely in a straight line shape by partially matching and bending the stretchable electric wire 240, so that when the stretchable electric wire 240 is subjected to a tensile force, the tensile force can be shared by the stretch-breaking prevention structure, rather than being completely borne by the stretchable electric wire 240, and thus the tensile force that the stretchable electric wire 240 can bear can be effectively improved. The actual anti-breaking effect of the anti-breaking structure 259 is affected by a plurality of factors such as the material of the retractable wire 240, the structure and the size of the anti-breaking structure 259, and in an actual product, the retractable wire 240 can bear the pulling force of 100N due to the arrangement of the anti-breaking structure 259.

The anti-breaking structure 259 can adopt different structures as required, in this embodiment, referring to fig. 12 again, the anti-breaking structure 259 includes a local limiting groove 252 for accommodating the retractable wire 240, and in detail, the limiting groove 252 is in positioning fit with the first connecting segment 242 of the retractable wire 240. The arrangement of the limiting groove 252 not only can realize the anti-breaking effect, but also can improve the orderliness and stability of the retractable wire 240 in the handle 210. The limiting groove 252 is located at the rear side of the fixing member 250, and one end of the limiting groove 252 is communicated with the notch 253 located at the top of the fixing member 250, and the other end extends to the bottom of the fixing member 250.

Further, the limiting groove 252 includes a straight line section and a bent section 252b, one end of the straight line section is communicated with one end of the bent section 252b, and the straight line section is matched with the straight line portion.

Specifically, the number of the straight line segments is two, and the two straight line segments are a first straight line segment 252a and a second straight line segment 252c, and the first straight line segment 252a, the bending segment 252b and the second straight line segment 252c are sequentially communicated from top to bottom to form the limiting groove 252. One end of the first straight line section 252a away from the bending section 252b is communicated with the notch 253 at the top of the fixing member 250, and one end of the second straight line section 252c away from the bending section 252b extends to the bottom of the fixing member 250.

The first straight line section 252a is matched with the first straight line section 242a so that the first straight line section 242a can be completely or partially embedded into the first straight line section 252a, the second straight line section 252c is matched with the second straight line section 242c so that the second straight line section 242c can be completely or partially embedded into the second straight line section 252c, and the bent section 252b is matched with the bent section 242b so that the bent section 242b can be completely or partially embedded into the bent section 252b, so that the anti-breaking effect of the limiting groove 252 on the telescopic electric wire 240 is realized, the limiting effect of the limiting groove 252 on the telescopic electric wire 240 is realized, and the orderliness and the stability of the telescopic electric wire 240 in the handle 210 are ensured.

The specific shape of the bent portion 252b can be set according to the requirement, and in this embodiment, since the bent portion 242b is arc-shaped and substantially in a transverse "U" shape, the bent portion 252b is also arc-shaped and substantially in a transverse "U" shape. In other embodiments, when the bent portion 242b has other shapes, the shape of the bent section 252b changes, for example, when the bent portion 242b has a substantially horizontal "V" shape, the bent section 252b also has a substantially horizontal "V" shape; for example, when the bent portion 242b is substantially rectangular with one side open, the bent section 252b is also substantially rectangular with one side open.
