Next, as shown in fig. 5 to 7, when the lamp head assembly 30 abuts against the push rod 512, so that the push rod 512 compresses the spring 514, the rod handle 513 drives the sliding block 523 to move towards two sides through the connecting rod 54, so that the contact pin 524 approaches the sliding rheostat 40 and abuts against the sliding rheostat 40, so as to realize the movement of the contact pin 524 on the sliding rheostat 40, and finally reaches fig. 7, that is, the displacement block 372 passes through and abuts against the bottom of the connecting cavity 11, at this time, the resistance value of the sliding rheostat 40 is minimum, the lamp 31 is brightest, that is, the lamp 31 gradually brightens as the spring 514 compresses.
The adjustable electric contact assembly 50 is driven by fine adjustment through the lamp holder assembly 30 connected with the screw thread, and finally the adjustable electric contact assembly abuts against the slide rheostat 40 back and forth, so that the resistance value of an access circuit of the slide rheostat 40 is controlled, the brightness of the bulb 31 is adjusted, the energy is saved, and meanwhile, electric shock protection is realized.
The foregoing description shows and describes several preferred embodiments of the invention, but as aforementioned, it is to be understood that the invention is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
