The locking member 9 of this embodiment is of an integral structure and is provided in a sheet structure, and protruding blocks 13 are provided at two ends of the locking member 9 in the length direction for being connected with the elastic element 11 in a matching manner. The locking piece 9 with an integrated structure is simple and reliable in structure and good in integrity, and is beneficial to increasing the area abutting against the section bar 1, so that the locking and fixing stability of the handle assembly 4 is improved.

Further, the connection members 6 are provided with at least one group, each group comprising two connection members 6. The locking member 9 is provided with at least one set of connecting holes 14 for cooperation with the connecting member 6, each set of connecting holes 14 comprising two connecting holes 14. The two connecting holes 14 of the same group are respectively positioned at two sides of the transmission shaft 5 of the handle assembly 4. Still further, in order to avoid the driving shaft 5 of the handle assembly 4, the locking member 9 is provided with a through hole 15, and the driving shaft 5 passes through the through hole 15 and is connected with a component (for example, a gear) of the driver 3.

Thus, when the handle assembly 4 is detached, after the connecting piece 6 is separated from the locking piece 9, the locking piece 9 is elastically reset under the action of the elastic element 11 and automatically moves to the side close to the driver 3 and is re-attached to the shell of the driver 3, and the attachment precision of the locking piece 9 and the driver 3 can be improved through the matching of the first positioning feature 16 and the second positioning feature 17, so that the locking piece 9 can be more accurately reset to the driver 3 under the action of the first positioning feature 16 and the second positioning feature 17. In order to further improve the resetting and positioning effect of the locking member 9, the guiding surface on the positioning boss of the present embodiment plays a guiding role, especially when the locking member 9 is driven by the connecting member 6, the locking member 9 is easy to deflect, and when the positioning boss (the first positioning feature 16) on the locking member 9 fails to match the positioning pit (the second positioning feature 17) during resetting, the guiding surface and the guiding surface can be accurately and stably corresponding to each other, so as to ensure that the locking member 9 can smoothly and accurately return to the driver 3.

As another embodiment, the first positioning feature 16 may be configured as a pit structure and the second positioning feature may be configured as a bump structure, which may also achieve positioning. Alternatively, other specific positioning structures may be used to achieve this, such as positioning pins and holes, bosses and grooves, and the like.

Preferably, the handle assembly 4 is provided with a base 10, and the base 10 is arranged on one side of the handle assembly 4 close to the section bar 1; the base 10 is provided with an assembly hole matched with the connecting piece 6.
