DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following further describes the present utility model in detail in conjunction with the drawings and the specific embodiments.

[0024] In this embodiment, refer to Figures 1-6, A kind of LED tool lamp that is convenient for adjusting the tilt angle in its specific implementation, including a housing 1 and a lamp head 2. The lamp head 2 is rotatably installed on the housing 1. A slidable tooth block 4 is installed in the lamp head 2 through a return spring 3. The housing 1 is provided with a tooth ring 5 for cooperating with the tooth block 4. The lamp head 2 is provided with a connecting part, and the connecting part is installed on the housing 1 through a rotating shaft. The connecting part is provided with a through hole, and the return spring 3 is installed in the through hole. The tooth blocks 4 are respectively installed at both ends of the return spring 3, and the tooth block 4 and the tooth ring 5 are meshed with each other through the return spring 3. When the user is using the tool lamp, by simply rotating the lamp head 2 or the housing 1, the angle of the lamp head 2 can be easily adjusted to meet various different lighting needs. In addition, the reset function of the return spring 3 further enhances the stability of the lamp head 2. When the user completes the angle adjustment, the reset ability of the return spring 3 makes the tooth block 4 firmly adhere to the tooth groove of the tooth ring 5, so that the rotation angle of the lamp head 2 is fixed. This ensures the stability and reliability of the lighting angle. Thus, the use of the LED tool lamp is more convenient and reliable.

[0025] Furthermore, stoppers (7) are provided at both ends of the tooth ring (5), and the lamp head (2) is provided with limit blocks (6) for cooperating with the stoppers (7). The design of the limit blocks 6 and the stoppers 7 ensures that the lamp head 2 can be blocked and stopped when it rotates to a preset angle. This avoids unnecessary wear or damage to the lamp head 2 itself or its housing 1 due to excessive rotation of the lamp head 2. Thereby, the service life of the lamp head 2 and the housing 1 is prolonged, and at the same time, the stability and safety of the device are ensured. This design not only improves the reliability of the product but also provides a more convenient and safe use experience for users.

[0026] Furthermore, the rotatable angle of the lamp head 2 is from -30 degrees to +90 degrees. Through the cooperation between the limit block 6 and the stopper 7, the lamp head 2 has the function of rotating downward to 30 degrees and upward to 90 degrees. While covering a wide lighting range from the ground to the ceiling, this avoids damage to the housing 1 or the lamp head 2 caused by excessive rotation. The user can easily adjust the lighting angle according to actual needs, and can obtain an ideal lighting effect whether it is for ground operations or high-altitude lighting.

[0027] Furthermore, the tooth rings 5 are evenly distributed around the rotation center of the lamp head 2. The even distribution of the tooth rings 5 ensures the stability of the lamp head 2 at various angles during rotation, enabling the user to feel consistent resistance and feedback when adjusting the lighting angle, thereby achieving precise positioning.

[0028] Furthermore, the shape of the tooth ring 5 is triangular. This design not only increases the contact area of meshing but also improves the strength and durability of the structure. The triangular tooth ring 5 performs better in bearing pressure and friction, thus ensuring that during long-term use, the meshing between the tooth block 4 and the tooth ring 5 is more stable and not prone to wear or damage.

[0029] Furthermore, the tooth block 4 is provided with a guiding structure 12 for cooperating with the tooth ring 5. The guiding structure 12 matches the shape of the tooth ring 5, ensuring that the tooth block 4 can accurately cooperate with the tooth ring 5 during the sliding process, thereby guaranteeing the accuracy of the angle adjustment of the lamp head 2. While making it smoother for the user to adjust the irradiation angle, it reduces the wear on the tooth ring, thus improving the service life and stability of the LED work light.

[0030] Furthermore, a sliding block 8 is provided on one side of the tooth block 4, and the lamp head 2 is provided with a sliding groove 9 for cooperating with the sliding block 8. Through the cooperation of the sliding block 8 and the sliding groove 9, the movement of the tooth block 4 becomes more stable and accurate, and it can only slide reciprocally along the sliding groove 9, avoiding the rotation of the tooth block 4 during use, which may affect the meshing effect with the tooth ring 5. This ensures the smoothness and reliability when the user adjusts the angle of the lamp head 2.

[0031] Furthermore, a battery compartment 10 is provided at the lower end of the housing 1. The setting of the battery compartment 10 makes the use of the work light more flexible and convenient. When working outdoors or in the absence of a power socket, the user can ensure the continuous use of the work light by installing a battery. The battery compartment 10 is designed at the lower end of the housing 1, which not only facilitates the user to replace the battery but also avoids the influence of the battery weight on the balance of the lamp head 2, thereby maintaining the stability of the work light and the comfort of operation.

[0032] Furthermore, a grippable handle 11 is provided on one side of the lamp head 2. The design of the handle 11 makes it more convenient for the user to adjust the angle of the lamp head 2 or move the work light. The user can easily grip the handle 11 for precise positioning and movement without directly contacting the lamp head 2, thus avoiding unnecessary injuries such as burns caused by hand contact with the lamp head 2, thereby improving the safety of the work light.

[0033] The beneficial effects of the present utility model: The tooth block 4 and the tooth ring 5 are meshed with each other through the return spring 3, enabling the user to easily adjust the angle of the lamp head 2 by rotating the lamp head 2, so as to meet different lighting requirements. And through the reset function of the return spring 3, it is ensured that the lamp head 2 can stably maintain the required angle after adjustment, thereby improving the convenience and stability of the LED work light.
