Referring to fig. 12, when a portion of the docking post 161 located in the positioning slot 410 enters the mounting hole 510, the portion contacts with two stoppers 940 located at the opening of the mounting hole 510, so as to push the reset cap 800 to compress the spring 700, and as the docking post 161 pushes the stoppers 940 into the mounting hole 510, the two supporting rings 900 are driven to rotate by the stoppers, in this process, the arc-shaped deflector 910 is turned away from the bottom of the base 500, i.e. the two arc-shaped deflector 910 are close to each other, and in the process of continuing to press the base 500, the two arc-shaped deflector 910 stretches into the annular space-avoiding slot 430;
the base 500 is pressed by continuing to apply force until the base 500 enters the positioning groove 410 until the bottom of the base 500 abuts against the bottom surface of the positioning groove 410, and at this time, the two arc-shaped deflector rods 910 are both positioned in the annular position avoiding groove 430 and are not contacted with the inner wall of the annular position avoiding groove 430, as shown in fig. 12.
Referring to fig. 13, finally, the adaptor 400 is rotated to rotate the adaptor 400 relative to the liftable support 10, the stop screw 421 on the inner wall of the through hole 420 starts to slide along the spiral chute 11, when the stop screw 421 enters the inclined section 11A from the stop section 11B, the adaptor 400 rises along the axial direction of the docking cylinder 161, at this time, the portion of the docking cylinder 161 located in the positioning slot 410 starts to move away from the mounting hole 510, the spring 700 stretches and pushes the reset cap 800 to move towards the opening position of the mounting hole 510, thereby pushing the abutment ring 900 to rotate reversely, the two arc-shaped deflector 910 start to separate from each other and abut against the inner wall of the annular space-avoiding slot 430, and the elastic force provided by the spring 700 is converted into the abutting force of the two arc-shaped deflector 910 and the inner wall of the annular space-avoiding slot 430, so as to fix the lamp socket 500 in the adaptor 400.
When the lamp holder 500 is required to be separated from the adaptor holder 500, the adaptor holder 400 is only required to be twisted reversely to draw out the lamp holder 500 from the adaptor holder 400.
The two movable propping rings 900 prop against the annular position avoidance groove 430 to provide friction force to prevent the lamp holder 500 from being separated from the adapter 400, even if the inner walls of the propping rings 900 and the annular position avoidance groove 430 are worn, the outward turning range of the lower arc-shaped deflector 910 at the left and right sides of the spring 700 is enlarged, the propping against the annular position avoidance groove 430 can be realized, the abrasion caused by frequent assembly and disassembly can be automatically adapted, and the adapter 400 is more durable. For the user, after the auxiliary positioning component is added, the step of docking the adapter 400 with the lamp holder 500 is only one more step, that is, the adapter 400 needs to be slightly twisted, so that the assembly and the disassembly are simple.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
