Figures 1-3, the bottom of the lamp head 14 is connected with the tilting transmission mechanism, the side of the lamp head 14 is rotatably connected with a lamp head fixing support 17, the lamp head fixing support 17 is arranged between the tilting pipe 7 and the tilting transmission mechanism, and the tilting transmission mechanism is used for transmitting the rotary motion of the tilting pipe 7 to the tilting swing motion of the lamp head 14; the tilting pipe 7 is sleeved with a push-pull pipe 6, the push-pull pipe 6 is provided with a first eccentric wheel locking mechanism, and the first eccentric wheel locking mechanism is used for locking the tilting pipe 7 and the push-pull pipe 6.

[0030] The upper push rod of the utility model adjusts the tilting of the lamp head 14 through the tilting transmission mechanism, can transmit the rotary motion of the lower tilting pipe 7 to the tilting swing motion of the lamp head 14, thereby realizing the function that the operator does not need to climb to the height of the lamp head 14 and can adjust the tilting angle of the lamp head 14 through the tilting pipe 7 below, and through the first eccentric wheel locking mechanism, the eccentric wheel can be locked after adjustment, the tilting pipe 7 is quickly locked at the current position, thereby locking the tilting angle of the lamp head 14, and the tilting adjustment and angle fixation of the lamp head 14 below are realized quickly, the upper push rod of the structure greatly simplifies the operation of the tilting adjustment of the lamp head 14, significantly improves the tilting adjustment convenience of the lamp head 14, prevents the safety hidden danger caused by the personnel climbing adjustment operation, and is more simple and efficient in operation, compared with the thread or buckle locking in the prior art, is more time-saving and labor-saving, and only needs one-hand operation to lock or loosen the first eccentric wheel locking mechanism and rotate the tilting pipe 7, which is more convenient and fast than the usual two-hand operation of the existing locking mechanism.

[0031] Specifically, when the tilting angle needs to be adjusted, the operator holds the tilting pipe 7 exposed below the push-pull pipe 6 with one hand on one side of the upper push rod, and rotates the tilting pipe 7 clockwise or counterclockwise according to the tilting direction to be adjusted, the rotary motion is transmitted to the lamp head 14 through the tilting transmission mechanism connected with the top end of the tilting pipe 7 and through the transmission of different motion directions such as connecting rods, so that the lamp head 14 rotates around the connection between the lamp head fixing support 17 and the lamp head 14 in the vertical plane, thereby realizing the function that the lamp head 14 can be adjusted in the low place; the top of the push-pull pipe 6 sleeved outside the tilting pipe 7 is also fixedly connected with the lamp head fixing support 17, when the push-pull pipe 6 is rotated, the lamp head fixing support 17 drives the lamp head 14 to rotate in the horizontal plane, when the push-pull pipe 6 is pushed and pulled to move up and down, the lamp head fixing support 17 drives the lamp head 14 to move up and down synchronously, and the rotation and height adjustment are realized. For the first eccentric wheel locking mechanism, the eccentric wheel is used for pressing the tilting pipe 7 inside to lock or loosen the motion thereof.

[0032] Embodiment 2: This embodiment is based on embodiment 1, please refer to Figure 1 、 Figure 6The pitch transmission mechanism includes a pitch swing arm 16 connected to the end of the pitch tube 7. The end of the pitch swing arm 16 is connected to a pitch fork 4 via a bearing 15. A pitch connecting rod 3 is rotatably connected to the pitch fork 4. A pitch pin 2 is connected to the pitch connecting rod 3. The pitch pin 2 is fixedly connected to the lamp head 14 via a pin base 1. The lamp head fixing bracket 17 is located between the pitch tube 7 and the pitch swing arm 16.

[0033] In this embodiment, the pitch transmission mechanism rotates, causing the pitch tube 7 to rotate and drive the pitch arm 16 to rotate on the lamp head fixing bracket 17. The pitch arm 16 drives the pitch fork 4 to rotate around the connection center between the pitch arm 16 and the pitch tube 7. Driven by this rotation, the pitch connecting rod 3 on the pitch fork 4, due to its connection with the lamp head 14, pulls the lamp head 14 downward or lifts it upward, thereby causing the lamp head 14 to pitch and rotate in the vertical plane. This structure transforms the rotational motion of the lower pitch tube 7 into the pitch motion of the lamp head 14 through transmission, eliminating the need for circuit control and the need to climb to operate the lamp head 14, significantly improving the convenience of operation.

[0034] Example 3: This example is based on Example 1. Please refer to Example 1.

The first manual lever 8 and the push-pull tube seat 11 are connected to the first lever spring 9.

[0035] In this embodiment, the first eccentric wheel locking mechanism is connected to the outer surface of the push-pull tube 6. The push-pull tube seat 11 has a push-pull tube groove, exposing a portion of the internal pitch tube 7. The first eccentric wheel 10 rotates to press the pitch tube 7 into the groove, thus locking the position of the pitch tube 7 and locking the pitch angle. When adjusting the pitch, the operator can hold the pitch tube 7 with one hand and press the first manual lever 8 with their finger. The first eccentric wheel 10 rotates to release the pitch, unlocking the pitch tube 7. The pitch tube 7 can then be rotated for pitch adjustment. After adjusting to the desired angle, the finger pressing the first manual lever 8 is released. The lever rebounds under the elastic action of the first lever spring 9, causing the first eccentric wheel 10 to rotate again and press the pitch tube 7 back into place, locking the position of the pitch tube 7 and preventing further movement. This embodiment's structure allows for quick adjustment and locking of the pitch tube 7 with only one hand, without contacting the lamp head 14, significantly reducing the complexity of the operation.
