In this embodiment, the first support rod 3 is inserted and fixed to the lamp socket 1. Through installing connecting bush 6 on first bracing piece 3 to make connecting bush 6 be connected with locating part 5 joint, so played the guard action to first bracing piece 3, and it is more convenient to change connecting bush 6, and the cost is also lower.

As a specific implementation manner of the retractable table lamp provided by the present invention, please refer to fig. 2 and fig. 4, the locking member 302 is a hand screw, and a threaded hole for installing the hand screw is correspondingly disposed on the side wall of the first supporting rod 3. In this embodiment, hand screw is the standard component, and purchasing convenience and low cost only need process out the installation screw on first bracing piece 3 can, and the processing cost is low. Through rotatory hand screw, the terminal surface of leaning on hand screw on the outer wall of connecting bush 6 to realized the fixed connection of first bracing piece 3 with connecting bush 6, this simple structure, convenient operation. Instead of hand screws, the retaining member 302 may also be threaded.

As a specific implementation manner of the retractable table lamp provided by the present invention, please refer to fig. 2 to 4, the limiting part 5 includes: two knock pins 501 and an elastic member 502. Two knock pins 501 are located inside the mount 7, and have freedom of movement in the axial direction of the knock pins 501; the two ejector pins 501 are coaxially arranged, the end parts of the ejector pins 501 sequentially penetrate through the side walls of the mounting base 7 and the second supporting rod 4, and a plurality of second clamping grooves 601 which are in clamping fit with the end parts of the ejector pins 501 are correspondingly formed in the side walls of the connecting bushings 6 along the length direction of the connecting bushings 6; the elastic member 502 is located between the two knock pins 501, and abuts against end surfaces of the two knock pins 501, for driving the two knock pins 501 to move outward in the axial direction of the knock pins 501. In this embodiment, the limiting member 5 and the second support rod 4 are separated, so that the processing difficulty is reduced. The cross-sectional shapes of the first cavity 301 and the second cavity 401 are both rectangular, the installation seat 7 is in sliding fit with the side wall of the second cavity 401, on one hand, it is guaranteed that the installation seat 7 and the second support rod 4 are connected more stably, and on the other hand, the installation accuracy of all the parts is guaranteed. The inside of mount pad 7 is equipped with the accommodation space who holds knock pin 501 and elastic component 502, corresponds on the lateral wall of mount pad 7 and offers the guide way 703 that is used for knock pin 501 to pass, guide way 703 and knock pin 501 sliding fit to with the one end of knock pin 501 spacing in the inside of mount pad 7. The side wall of the second support bar 4 is provided with a yielding groove 403 corresponding to the guide groove 703, and the size of the yielding groove 403 is larger than or equal to that of the guide groove 703. Through applying inward pressure to two knock pins 501, make knock pin 501 shrink to the groove 403 of stepping down, the both ends of elastic component 502 are compressed simultaneously and take place to warp, at this moment, second bracing piece 4 can freely slide on connecting bush 6 along the length direction of connecting bush 6, slide to suitable height when second bracing piece 4, knock pin 501 just aligns with second draw-in groove 601, the pressure that knock pin 501 receives disappears, elastic component 502 orders about two knock pin 501's tip simultaneously and removes to second draw-in groove 601 in, thereby fix second bracing piece 4 joint on connecting bush 6, prevent second bracing piece 4 from continuing to slide. Because the connecting bush 6 is located inside the first cavity 301, the first supporting rod 3 can plug the second clamping groove 601 on the connecting bush 6 inside the first supporting rod 3, so that the overall aesthetic property of the desk lamp is improved. The connecting bush 6 can move on the first supporting rod 3 along the length direction of the first supporting rod 3, and the height of the desk lamp can be changed by adjusting the position height of the first supporting rod 3.

As a specific embodiment of the retractable table lamp provided in the present invention, please refer to fig. 2 to fig. 4, the bottom of the mounting seat 7 is provided with a limiting flange 704, and the limiting flange 704 abuts against the bottom end face of the second support rod 4.
