[0024] First side spring grooves 6 are symmetrically arranged on the two sides of the second support plate 5, first springs 7 are fixedly connected to the inner side of the first side spring grooves 6, the other end of the first spring 7 is fixedly connected with a first round head jackscrew 8, and the first spring 7 and the first round head jackscrew 8 are designed to fix the second support plate 5 by the first round head jackscrew 8 extending into the corresponding first side fixed hole 4 after the second support plate 5 is adjusted to the appropriate position, so as to prevent the second support plate 5 from sliding.

[0025] Second side spring grooves 19 are symmetrically arranged on the two sides of the lower sliding base 16, second springs 20 are fixedly connected to the inner side of the second side spring grooves 19, the other end of the second spring 20 is fixedly connected with a second round head jackscrew 21, and a manual push rod 22 is fixedly connected to the side of the lower sliding base 16, so that the lower sliding base 16 can be pushed to slide along the sliding inclined groove 15 through the manual push rod 22, and when sliding to the appropriate position, the second spring 20 pushes the second round head jackscrew 21 to extend into the corresponding second side fixed hole 11, so as to fix the position of the lower sliding base 16.

[0026] The first side fixed hole 4 penetrates from the outer side of the first support plate 2 to the inner side of the upper support plate sliding groove 3, and this design allows the first round head jackscrew 8 to extend from the first side spring groove 6 under the action of the spring and pass through the first side fixed hole 4 to fix the position of the second support plate 5.

[0027] The sliding horizontal rod 17 is matched with the sliding chute 15, and the sliding horizontal rod 17 slides in the inside of the sliding chute 15; the matching design of the sliding horizontal rod 17 and the sliding chute 15 allows the lower sliding base 16 to smoothly slide along the sliding chute 15 within a fixed angle range, so as to realize the rotation adjustment of the fixed lamp holder 13;

[0028] The limiting sliding block 18 is matched with the limiting sliding groove 12, and the limiting sliding block 18 is slidably connected in the inside of the limiting sliding groove 12, so as to limit the sliding direction of the lower sliding base 16; the matching design of the limiting sliding block 18 and the limiting sliding groove 12 ensures that the lower sliding base 16 will not deviate from the predetermined path during the sliding process, and keeps the stable sliding direction;

[0029] When the first spring 7 is naturally elongated without external force, the head part of the first round head jacking column 8 is exposed in the first side spring groove 6 and extends into the inside of the corresponding first side fixed hole 4; when the first spring 7 is in the natural state, the first round head jacking column 8 will automatically extend and be inserted into the corresponding first side fixed hole 4, so as to lock the position of the second supporting plate 5;

[0030] When the second spring 20 is naturally elongated without external force, the head part of the second round head jacking column 21 is exposed in the second side spring groove 19 and extends into the inside of the corresponding second side fixed hole 11; when the second spring 20 is in the natural state, the second round head jacking column 21 will automatically extend and be inserted into the corresponding second side fixed hole 11, so as to lock the position of the lower sliding base 16 and ensure the stability of the lamp.

[0031] The working principle of the utility model is: when the lamp pole adjusting device is in an unadjusted state, the second supporting plate 5 is fixed in a certain group of first side fixed holes 4 through the first round head jacking column 8 under the action of the first spring 7, so as to determine the vertical position of the second supporting plate 5 in the upper supporting plate sliding groove 3; the lower sliding base 16 is fixed in a certain group of second side fixed holes 11 through the second round head jacking column 21 under the action of the second spring 20;

[0032] When it is needed to adjust the vertical height of the lamp, the elastic force of the first spring 7 is overcome first, the first round head jacking column 8 is pulled out of the current first side fixed hole 4, then the second supporting plate 5 is slid along the upper supporting plate sliding groove 3 to the required position; at this time, the second supporting plate 5 is slightly slid up and down, so that the first round head jacking column 8 is automatically inserted into the first side fixed hole 4 in the new corresponding position under the action of the first spring 7, thereby fixing the new position of the second supporting plate 5;

[0033] When the rotation angle of the lamp is needed to be adjusted, the lower sliding base 16 is first pushed along the sliding chute 15 by the manual push rod 22 to overcome the elastic force of the second spring 20, and the second round head jackscrew 21 is extruded out of the current second side fixed opening 11. Due to the adaptive design of the limiting slider 18 and the limiting sliding groove 12, the lower sliding base 16 will keep a stable sliding direction. At this time, the sliding crossbar 17 slides inside the sliding chute 15 and drives the slotted inclined plate 14 and the fixed lamp holder 13 to rotate. When moving to the appropriate position, the manual push rod 22 is slightly pushed forward and backward, so that the second round head jackscrew 21 is automatically inserted into the second side fixed opening 11 in the new corresponding position under the action of the second spring 20, thereby fixing the new position of the lower sliding base 16, and realizing the rotation adjustment of the fixed lamp holder 13.

[0034] The lamp is installed on the device through the fixed lamp holder 13, and the rotation adjustment and the vertical height adjustment of the fixed lamp holder 13 together realize the accurate positioning of the lamp under different lighting requirements.
