[0005] However, when the flexible shaft is used in a skylight, the flexible shaft and the slider are connected by a thread, that is, the threaded end of the flexible shaft is screwed into the threaded groove on the slider by rotating the flexible shaft or the slider, and the slider can only slide along the direction of the guide groove under the limiting effect of the guide groove in the skylight frame. Therefore, when the flexible shaft needs to be removed, the flexible shaft and the slider need to be removed from the skylight frame together before the slider can be rotated to remove the flexible shaft. Therefore, when reinstalling the flexible shaft, the slider needs to be coupled to the guide groove again, which leads to a certain inconvenience when replacing the flexible shaft. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a car sunroof flexible shaft that is convenient to disassemble and assemble, so that the flexible shaft can be disassembled and assembled without removing the slider, thereby improving the overall disassembly and assembly efficiency of the flexible shaft.

[0010] The utility model is further configured as follows: the peripheral wall of the sleeve is provided with an annular groove formed by a depression, and the annular grooves are multiple and are spaced apart from each other along the axial direction.

[0011] The utility model is further configured as follows: the ejection groove is located on a side facing the accommodating groove and is provided with a limiting side wall whose inner diameter decreases successively toward the accommodating groove, and the limiting side wall is used to limit the steel ball to prevent the steel ball from escaping from the ejection groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Since a connecting end is provided on the flexible shaft body and a connecting tube is provided on the slider, when the flexible shaft body needs to be installed, the slider is first slid in a direction away from the flexible shaft slide groove in the skylight frame to increase the spacing between the slider and the flexible shaft slide groove, and then the sliding sleeve is used to allow the pressing portion to be offset from the ejection groove, and then the connecting end is inserted into the slot, and then the sliding sleeve is used to allow the pressing portion to be aligned with the ejection groove, and then the pressing portion can press the steel ball, and the connection end can be fixed by tightening the steel ball against the connecting end, and then the flexible shaft body is pushed into the flexible shaft slide groove to complete the installation of the flexible shaft body. Similarly, when the flexible shaft body needs to be removed, first pass By sliding the sleeve so that the pressing part and the ejection groove are offset, the connecting end can be separated from the slider, and then the slider is slid in the direction away from the flexible shaft slide groove in the skylight frame to increase the distance between the slider and the flexible shaft slide groove, and the flexible shaft body can be pulled out from the flexible shaft slide groove to complete the disassembly of the flexible shaft body. In this way, there is no need to remove the slider, and the disassembly and assembly of the flexible shaft body can be completed only by sliding the slider. Therefore, the technical problem in the prior art that when the flexible shaft needs to be removed, the flexible shaft and the slider need to be removed from the skylight frame together is effectively solved, thereby reducing the number of disassembly and assembly of components in the skylight frame and improving the overall disassembly and assembly efficiency of the flexible shaft.
