Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a table lamp with a telescopic structure. Background Technology

[0002] With the accelerating pace of modern life and the ever-increasing demand for high-quality lighting, desk lamps, as a flexible and efficient lighting tool, have been widely used in various settings such as homes, offices, and study areas. When reading, writing, working, or engaging in craft activities, people often need desk lamps to provide focused and soft light to protect their eyesight and improve work efficiency.

[0003] Existing desk lamps typically have a lamp head to provide a light source. However, the position of the lamp head cannot be adjusted forward or backward or extended. When users need to adjust the lighting position of the lamp head, they often have to move the entire desk lamp, which is inconvenient.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] Regarding the aforementioned problem that existing desk lamps typically have a lamp head to provide a light source, but the position of the lamp head cannot be adjusted forward or backward or extended, and users often need to move the entire desk lamp to adjust the lighting position of the lamp head, which is inconvenient, the technical solution adopted by this utility model to solve this problem is:

[0006] A desk lamp with a telescopic structure includes a desk lamp body, the desk lamp body including a lamp head assembly and a support assembly, the support assembly including a movable telescopic rod connected to the lamp head assembly and a fixed connecting rod sleeved on the outer wall of the movable telescopic rod, a telescopic mechanism is provided between the movable telescopic rod and the fixed connecting rod, the movable telescopic rod is slidably connected to the fixed connecting rod through the telescopic mechanism, so that the lamp head assembly moves closer to or further away from the fixed connecting rod.

[0007] Furthermore, a rotating mechanism is provided between the lamp head assembly and the movable telescopic rod, and the lamp head assembly is rotatably connected to the movable telescopic rod through the rotating mechanism.

[0008] Furthermore, the telescopic mechanism includes a slide rail mechanism located on the inner side wall of the fixed connecting rod, a slide groove mechanism located on the outer side wall of the movable telescopic rod and slidably connected to the slide rail mechanism, and a limiting member extending through the fixed connecting rod and toward the slide groove mechanism. When the slide groove mechanism moves relative to the slide rail mechanism, the limiting member abuts against the inner side wall of the slide groove mechanism to limit the movement range of the movable telescopic rod.

[0009] Furthermore, the telescopic mechanism includes positioning holes located on the slide mechanism and engaging with the limiting member, the positioning holes being spaced apart along the length direction of the slide mechanism.

[0010] Furthermore, the movable telescopic rod includes a hollow connecting sleeve rod located on the side away from the fixed connecting rod. The rotating mechanism includes a mounting part on the lamp head assembly, a mounting through hole on the side of the connecting sleeve rod near the lamp head assembly, and a fixing mechanism located between the mounting part and the mounting through hole. The mounting part extends into the mounting through hole and is rotatably connected to the connecting sleeve rod through the fixing mechanism. A fixing space for clamping the connecting sleeve rod is formed between the mounting part and the fixing mechanism.

[0011] Furthermore, the mounting part includes an extension shaft extending toward the mounting through hole, and the fixing mechanism includes a limiting nut, an elastic clamping member, and a washer. The limiting nut, the elastic clamping member, and the washer are all sleeved on the outer side wall of the extension shaft and are arranged vertically along the height direction of the extension shaft.

[0012] Furthermore, the connecting sleeve rod and the fixed connecting rod are the same size. When the movable telescopic rod approaches the fixed connecting rod, the ends of the connecting sleeve rod and the fixed connecting rod are connected, and the outer side wall of the connecting sleeve rod is flush with the outer side wall of the fixed connecting rod.

[0013] Furthermore, the slide rail mechanism includes a first slide rail located on the side wall of the fixed connecting rod and a second slide rail corresponding to the first slide rail.

[0014] Furthermore, the slide rail mechanism includes a third slide rail located above the first slide rail, the cross-section of the third slide rail being U-shaped, and the slide groove mechanism includes a third slide groove slidably connected to the third slide rail.

[0015] Furthermore, the mounting part and the extension shaft are in the form of a boss, and the mounting part has a mounting end face on the side near the extension shaft, and the washer is located on the mounting end face.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features a movable telescopic rod, a fixed connecting rod, and a telescopic mechanism located between the movable telescopic rod and the fixed connecting rod. The movable telescopic rod is connected to the lamp head assembly. When the user needs to adjust the lighting position of the lamp head assembly, the telescopic mechanism allows the movable telescopic rod to move closer to or further away from the fixed connecting rod, thereby adjusting the lighting position of the lamp head assembly without moving the entire lamp body. This improves the convenience and flexibility of using the lamp body and effectively solves the problem that existing lamps typically have a lamp head to provide a light source, but the position of the lamp head cannot be adjusted forward or backward or extended. When the user needs to adjust the lighting position of the lamp head, they often need to move the entire lamp, which is inconvenient.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 8The table lamp shown includes a lamp body 1, which includes a lamp head assembly 2 and a support assembly 3. The support assembly 3 includes a movable telescopic rod 31 connected to the lamp head assembly 2 and a fixed connecting rod 32 sleeved on the outer wall of the movable telescopic rod 31. A telescopic mechanism 4 is provided between the movable telescopic rod 31 and the fixed connecting rod 32. The movable telescopic rod 31 is slidably connected to the fixed connecting rod 32 through the telescopic mechanism 4, so that the lamp head assembly 2 can move closer to or further away from the fixed connecting rod 32.

[0029] This invention features a movable telescopic rod, a fixed connecting rod, and a telescopic mechanism located between the movable telescopic rod and the fixed connecting rod. The movable telescopic rod is connected to the lamp head assembly. When the user needs to adjust the lighting position of the lamp head assembly, the telescopic mechanism allows the movable telescopic rod to move closer to or further away from the fixed connecting rod, thereby adjusting the lighting position of the lamp head assembly without moving the entire lamp body. This improves the convenience and flexibility of using the lamp body and effectively solves the problem that existing lamps typically have a lamp head to provide a light source, but the position of the lamp head cannot be adjusted forward or backward or extended. When the user needs to adjust the lighting position of the lamp head, they often need to move the entire lamp, which is inconvenient.

[0030] Furthermore, the telescopic mechanism 4 reduces safety hazards caused by frequent movement of the lamp body 1. Users do not need to frequently move the entire lamp body 1 to adjust the lighting position, thereby reducing the risk of the lamp body 1 tipping over or the power cord being accidentally pulled, which helps to improve the safety of use.

[0031] Optionally, in some embodiments, the telescopic mechanism 4 includes an external thread located on the outer side wall of the movable telescopic rod 31 and an internal thread located on the inner side wall of the fixed connecting rod 32 that matches the external thread. When the user needs to adjust the position of the lamp body 1, the movable telescopic rod 31 is rotated, and the movement of the movable telescopic rod 31 relative to the fixed connecting rod 32 is achieved by using the engagement of the threads, thereby adjusting the position of the lamp body 1.

[0032] Optionally, in some embodiments, the telescopic mechanism 4 includes a first limiting through hole located on the movable telescopic rod 31, a second limiting through hole located on the fixed connecting rod 32, and a limiting pin that simultaneously engages with both the first and second limiting through holes. The first limiting through holes are spaced apart along the length of the movable telescopic rod 31, and the second limiting through holes are spaced apart along the length of the fixed connecting rod 32. When the user needs to adjust the position of the lamp body 1, the limiting pin is pulled out, and the movable telescopic rod 31 and the fixed connecting rod 32 are in an unlocked state. The movable telescopic rod 31 can move freely relative to the fixed connecting rod 32, thereby adjusting the position of the lamp body 1. When the position is adjusted to a suitable position, the limiting pin is reinserted, and the limiting pin simultaneously engages with both the first and second limiting through holes, and the movable telescopic rod 31 and the fixed connecting rod 32 are in a locked state.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the telescopic mechanism 4 includes a slide rail mechanism 41 located on the inner side wall of the fixed connecting rod 32, a slide groove mechanism 42 located on the outer side wall of the movable telescopic rod 31 and slidably connected to the slide rail mechanism 41, and a limiting member 43 extending through the fixed connecting rod 32 and extending toward the slide groove mechanism 42.

[0034] Specifically, the fixed connecting rod 32, the movable telescopic rod 31, and the connecting sleeve rod 311 are all hollow structures. The limiting nut 531, the elastic clamping member 532, the washer 533, the extension shaft 511, and the mounting part 51 are all provided with wire holes for power supply wires to pass through. The wires pass through the fixed connecting rod 32 and the movable telescopic rod 31 in sequence to the connecting sleeve rod 311, and then pass through the limiting nut 531, the elastic clamping member 532, the washer 533, the extension shaft 511, and the mounting part 51 in the vertical direction from top to bottom to the lamp head assembly 2, thereby providing power to the lamp head assembly 2.

[0035] like Figures 1 to 8 A rotating mechanism 5 is provided between the lamp head assembly 2 and the movable telescopic rod 31 shown, and the lamp head assembly 2 is rotatably connected to the movable telescopic rod 31 through the rotating mechanism 5;

[0036] Furthermore, the rotating mechanism 5 allows the lamp head assembly 2 to rotate, so that the user can easily adjust the illumination direction of the lamp head assembly 2 according to actual needs.

[0037] Furthermore, since the lamp head assembly 2 can rotate, users do not need to move the entire lamp body 1 when they need to adjust the lighting direction. This not only saves users time and effort, but also reduces safety hazards such as wire tangling and lamp tipping caused by frequent movement of the lamp body 1.

[0038] Optionally, in some embodiments, the rotating mechanism 5 includes a universal joint located between the lamp head assembly 2 and the movable telescopic rod 31. The lamp head assembly 2 is connected to the movable telescopic rod 31 via the universal joint. The universal joint consists of two mutually perpendicular rotating shafts, each of which can rotate independently. The universal joint is provided with a locking nut, which the user can tighten or loosen to fix or adjust the position of the lamp head assembly 2.

[0039] Optionally, in some embodiments, the rotating mechanism 5 includes a rotary bearing located between the lamp head assembly 2 and the movable telescopic rod 31. The lamp head assembly 2 is connected to the movable telescopic rod 31 via the rotary bearing. The rotary bearing can be a one-way bearing or a multi-way bearing. The outer ring of the rotary bearing is fixedly connected to the movable telescopic rod 31, and the inner ring of the rotary bearing is fixedly connected to the lamp head assembly 2. The user can manually rotate the lamp head assembly 2 so that it can rotate freely in the inner ring of the rotary bearing, thereby rotating the lamp head assembly 2.

[0040] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the movable telescopic rod 31 includes a connecting sleeve rod 311 located on the side away from the fixed connecting rod 32 and having a hollow structure. The rotating mechanism 5 includes a mounting part 51 located on the lamp head assembly 2, a mounting through hole 52 located on the side of the connecting sleeve rod 311 near the lamp head assembly 2, and a fixing mechanism 53 located between the mounting part 51 and the mounting through hole 52. The mounting part 51 extends into the mounting through hole 52 and is rotatably connected to the connecting sleeve rod 311 through the fixing mechanism 53. A fixing space for clamping the connecting sleeve rod 311 is formed between the mounting part 51 and the fixing mechanism 53.

[0041] like Figures 1 to 8 The telescopic mechanism 4 shown includes a slide rail mechanism 41 located on the inner side wall of the fixed connecting rod 32, a slide groove mechanism 42 located on the outer side wall of the movable telescopic rod 31 and slidably connected to the slide rail mechanism 41, and a limiting member 43 extending through the fixed connecting rod 32 and toward the slide groove mechanism 42. When the slide groove mechanism 42 moves relative to the slide rail mechanism 41, the limiting member 43 abuts against the inner side wall of the slide groove mechanism 42 to limit the movement range of the movable telescopic rod 31.

[0042] Furthermore, the slide rail mechanism 41 is located on the inner wall of the fixed connecting rod 32, while the slide groove mechanism 42 is located on the outer wall of the movable telescopic rod 31, so that the movable telescopic rod 31 always stays on the predetermined track during the sliding process, avoiding shaking or deviation during the extension and retraction process, and ensuring the smoothness of the extension and retraction action.

[0043] Furthermore, the limiting member 43 passes through the fixed connecting rod 32 and extends to the sliding mechanism 42. When the sliding mechanism 42 moves to the limit position, the limiting member 43 abuts against the inner wall of the sliding mechanism 42, thereby limiting the movement range of the movable telescopic rod 31. This helps to prevent the movable telescopic rod 31 from extending or retracting excessively and avoids structural damage caused by exceeding the set range.

[0044] Furthermore, during the use of the desk lamp, the movable telescopic rod 31 will bear the weight from the lamp head assembly 2 and the external forces that may be applied. Through the cooperation of the slide rail mechanism 41 and the slide groove mechanism 42, these forces can be evenly distributed across the entire sliding contact surface, avoiding excessive local stress. This can effectively reduce wear and damage to components, extend the service life of the telescopic mechanism 4, and improve the overall stability and reliability of the desk lamp body 1.

[0045] Optionally, the limiting element 43 is a pin or a screw.

[0046] like Figures 1 to 8 The telescopic mechanism 4 shown includes a positioning hole located on the slide mechanism 42 and inserted into the limiting member 43. The positioning holes are spaced apart along the length direction of the slide mechanism 42.

[0047] Furthermore, once the movable telescopic rod 31 is fixed to the limiting member 43 through the positioning hole, it can effectively prevent it from sliding accidentally due to external force during use. This helps to ensure that the lamp head assembly 2 remains stable in the adjusted position, avoids affecting the lighting effect due to changes in the position of the lamp head assembly 2, and provides users with continuous and stable lighting.

[0048] Furthermore, the insertion and engagement of the positioning hole and the limiting member 43 increases the connection strength and stability of the telescopic mechanism 4. Compared with relying solely on friction or other simple fixing methods, the insertion structure can better withstand the weight of the lamp head assembly 2 and the external forces that may be applied, reducing wear and loosening between components and extending the service life of the telescopic mechanism 4.

[0049] Furthermore, when the user needs to adjust the position of the lamp head assembly 2, he / she only needs to pull the limiting member 43 out of the current positioning hole, then slide the movable telescopic rod 31 to the appropriate position, and then insert the limiting member 43 into the corresponding positioning hole to complete the adjustment. The whole operation process is simple and easy to understand, without complicated tools or operation steps, and can quickly change the position of the lamp head assembly 2, improving the efficiency of use.

[0050] like Figures 1 to 8The movable telescopic rod 31 shown includes a connecting sleeve rod 311 with a hollow structure located on the side away from the fixed connecting rod 32. The rotating mechanism 5 includes a mounting part 51 located on the lamp head assembly 2, a mounting through hole 52 located on the side of the connecting sleeve rod 311 near the lamp head assembly 2, and a fixing mechanism 53 located between the mounting part 51 and the mounting through hole 52. The mounting part 51 extends into the mounting through hole 52 and is rotatably connected to the connecting sleeve rod 311 through the fixing mechanism 53. A fixing space for clamping the connecting sleeve rod 311 is formed between the mounting part 51 and the fixing mechanism 53.

[0051] Specifically, the mounting part 51 extends from bottom to top into the connecting sleeve rod 311 through the mounting through hole 52 and is rotatably connected to the connecting sleeve rod 311 via the fixing mechanism 53. This allows the lamp head assembly 2 to be installed at the lower part of the connecting sleeve rod 311, forming a fixed space between the mounting part 51 and the fixing mechanism 53 for clamping the connecting sleeve rod 311. In actual use, the lamp head assembly 2 can rotate within the mounting through hole 52 under external force, allowing it to rotate relative to the connecting sleeve rod 311, thereby improving the flexibility of use of the lamp head assembly 2.

[0052] Furthermore, the fixing mechanism 53 can provide sufficient clamping force to prevent the lamp head assembly 2 from loosening or shaking due to external forces during use, thereby extending the service life of the lamp body 1.

[0053] Furthermore, the connecting sleeve 311 adopts a hollow structure, which helps to reduce the overall weight of the lamp body 1.

[0054] Optionally, the connecting sleeve 311 can be installed on the side of the movable telescopic rod 31 away from the fixed connecting rod 32 using a connection method such as threaded connection, snap-fit ​​connection, or slot connection.

[0055] like Figures 1 to 8 The mounting part 51 shown includes an extension shaft 511 extending toward the mounting through hole 52. The fixing mechanism 53 includes a limiting nut 531, an elastic clamping member 532, and a washer 533. The limiting nut 531, the elastic clamping member 532, and the washer 533 are all sleeved on the outer side wall of the extension shaft 511 and are arranged vertically along the height direction of the extension shaft 511.

[0056] Specifically, the extension shaft 511 extends into the connecting sleeve 311 through the mounting through hole 52, the limiting nut 531 is located at the end of the extension shaft 511 away from the mounting part 51, the elastic clamping member 532 is located between the limiting nut 531 and the inner wall of the connecting sleeve 311, and the washer 533 is located between the mounting part 51 and the outer wall of the connecting sleeve 311, forming a fixed space between the elastic clamping member 532 and the washer 533.

[0057] Furthermore, the extension shaft 511 provides a stable axis for the connection between the lamp head assembly 2 and the movable telescopic rod 31. The limiting nut 531 is set on the extension shaft 511, which can stably connect the lamp head assembly 2 and the connecting sleeve rod 311 together, preventing the lamp head assembly 2 from accidentally falling off during use.

[0058] like Figures 1 to 8 The connecting sleeve rod 311 and the fixed connecting rod 32 shown are the same size. When the movable telescopic rod 31 approaches the fixed connecting rod 32, the ends of the connecting sleeve rod 311 and the fixed connecting rod 32 are connected, and the outer side wall of the connecting sleeve rod 311 is flush with the outer side wall of the fixed connecting rod 32.

[0059] Furthermore, the outer walls of the connecting sleeve rod 311 and the fixed connecting rod 32 are flush, making the appearance of the entire lamp body 1 neater and more uniform, without any abrupt parts, so that the lamp body 1 looks more beautiful and harmonious when the telescopic function is not in use; secondly, the flush outer walls can hide the internal structure of the telescopic mechanism 4, avoiding the exposure of too many mechanical parts, thereby improving the overall aesthetics of the device.

[0060] Furthermore, the connecting sleeve rod 311 and the fixed connecting rod 32 are the same size and have flush outer walls, so that the lamp body 1 is more compact and occupies less space when it is retracted.

[0061] Furthermore, the flush outer wall design allows the connecting sleeve rod 311 and the fixed connecting rod 32 to distribute pressure more evenly when under stress, avoiding structural damage caused by excessive local stress, thereby extending the service life of the lamp body 1.

[0062] like Figures 1 to 8 The slide rail mechanism 41 shown includes a first slide rail 411 located on the side wall of the fixed connecting rod 32, and a second slide rail 412 corresponding to the first slide rail 411. The cross-sections of the first slide rail 411 and the second slide rail 412 are both "C" shaped. The slide groove mechanism 42 includes a first slide groove 421 slidably connected to the first slide rail 411, and a second slide groove 422 slidably connected to the second slide rail 412.

[0063] Furthermore, by setting the first slide rail 411 and the second slide rail 412, as well as the corresponding first slide groove 421 and the second slide groove 422, the sliding of the movable telescopic rod 31 within the fixed connecting rod 32 is more stable. The setting of the double slide rail can effectively prevent the movable telescopic rod 31 from shaking or shifting during the sliding process, ensuring the smoothness of the telescopic action.

[0064] Furthermore, the "C"-shaped structure can effectively reduce the contact area between the slide rail and the slide groove, reducing friction. This allows users to exert less force when pulling the movable telescopic rod 31 to extend or retract, making operation easier and smoother. Users can quickly and flexibly adjust the length of the telescopic rod according to actual needs, improving ease of use.

[0065] Furthermore, the dual-rail configuration can distribute the weight and external force of the movable telescopic rod 31 to the two rails instead of concentrating it on a single rail. This way of distributing the force can effectively reduce the load on each rail, thereby improving the structural strength and durability of the entire telescopic mechanism 4.

[0066] Specifically, the first slide rail 411 is integrally formed on one side of the inner wall of the fixed connecting rod 32, and the second slide rail 412 is integrally formed on the other side of the inner wall of the fixed connecting rod 32. The integral forming setting makes the slide rail and the fixed connecting rod an inseparable whole, avoiding problems such as loosening and breakage of the connection parts that may occur when using traditional connection methods.

[0067] like Figures 1 to 8 The slide rail mechanism 41 shown includes a third slide rail 413 located above the first slide rail 411. The cross-section of the third slide rail 413 is U-shaped. The slide groove mechanism 42 includes a third slide groove 423 that is slidably connected to the third slide rail 413.

[0068] Furthermore, by adding a third slide rail 413 to the first slide rail 411 and the second slide rail 412, the movable telescopic rod 31 is subject to more constraints during the sliding process. The multi-layer slide rail setting can effectively prevent the movable telescopic rod 31 from shaking or deviating during the sliding process, ensuring the smoothness and accuracy of the telescopic action.

[0069] Furthermore, the U-shaped slide rail has high structural strength and can withstand large lateral and axial forces, ensuring that it will not deform or be damaged under frequent extension and retraction operations.

[0070] Furthermore, the U-shaped third slide rail 413 can effectively prevent the movable telescopic rod 31 from derailing during sliding. The protruding parts on both sides of the U-shape can limit the movement range of the third slide groove 423, ensuring that the movable telescopic rod 31 always slides within the predetermined track, thereby improving the safety and reliability of the telescopic mechanism 4.

[0071] like Figures 1 to 8 The mounting portion 51 and the extension shaft 511 shown are in the shape of a boss. The mounting portion 51 is provided with a mounting end face 512 on the side near the extension shaft 511, and the washer 523 is located on the mounting end face 512.

[0072] Furthermore, the boss-shaped configuration provides a clear positioning reference for the installation of components. The mounting part 51 and the extension shaft 511 form a step through the boss structure, so that each component can accurately find its installation position during the assembly process, ensuring the accuracy and consistency of the installation. The washer 523 is placed on the mounting end face 512 and can be accurately positioned in the required position with the help of the positioning effect of the boss, thereby making the entire connection structure more stable.

[0073] Furthermore, when the mounting part 51 is connected to other components and bears loads, the washer 523 can distribute the pressure evenly on the mounting end face 512, which helps to avoid local stress concentration, enabling the mounting part 51 and the components connected to it to bear external forces more evenly, thereby improving the load-bearing capacity and stability of the entire connection structure.

[0074] Optionally, the side of the mounting part 51 away from the extension shaft 511 can be connected by threaded connection, snap-fit ​​connection, slot connection or other connection methods and can be detachably connected to the lamp holder assembly 2.

[0075] The implementation method of Example 1 is as follows:

[0076] A desk lamp with a telescopic structure includes a desk lamp body 1. The desk lamp body 1 includes a lamp head assembly 2 and a support assembly 3. The support assembly 3 includes a movable telescopic rod 31 connected to the lamp head assembly 2 and a fixed connecting rod 32 sleeved on the outer wall of the movable telescopic rod 31. A telescopic mechanism 4 is provided between the movable telescopic rod 31 and the fixed connecting rod 32. The movable telescopic rod 31 is slidably connected to the fixed connecting rod 32 through the telescopic mechanism 4, so that the lamp head assembly 2 can move closer to or further away from the fixed connecting rod 32.

[0077] This invention features a movable telescopic rod, a fixed connecting rod, and a telescopic mechanism located between the movable telescopic rod and the fixed connecting rod. The movable telescopic rod is connected to the lamp head assembly. When the user needs to adjust the lighting position of the lamp head assembly, the telescopic mechanism allows the movable telescopic rod to move closer to or further away from the fixed connecting rod, thereby adjusting the lighting position of the lamp head assembly without moving the entire lamp body. This improves the convenience and flexibility of using the lamp body and effectively solves the problem that existing lamps typically have a lamp head to provide a light source, but the position of the lamp head cannot be adjusted forward or backward or extended. When the user needs to adjust the lighting position of the lamp head, they often need to move the entire lamp, which is inconvenient.

[0078] The implementation method of Example 2 is as follows:

[0079] Based on Embodiment 1, Embodiment 2 further includes the following implementation: A rotating mechanism 5 is provided between the lamp head assembly 2 and the movable telescopic rod 31, and the lamp head assembly 2 is rotatably connected to the movable telescopic rod 31 through the rotating mechanism 5.

[0080] The implementation method of Example 3 is as follows:

[0081] Based on Embodiment 1, Embodiment 3 further includes the following implementation: The telescopic mechanism 4 includes a slide rail mechanism 41 located on the inner wall of the fixed connecting rod 32, a slide groove mechanism 42 located on the outer wall of the movable telescopic rod 31 and slidably connected to the slide rail mechanism 41, and a limiting member 43 extending through the fixed connecting rod 32 and toward the slide groove mechanism 42. When the slide groove mechanism 42 moves relative to the slide rail mechanism 41, the limiting member 43 abuts against the inner wall of the slide groove mechanism 42 to limit the movement range of the movable telescopic rod 31.

[0082] The implementation method of Example 4 is as follows:

[0083] Based on Embodiment 3, Embodiment 4 also has the following implementation method: The telescopic mechanism 4 includes a positioning hole located on the slide mechanism 42 and engaged with the limiting member 43. The positioning holes are spaced apart along the length direction of the slide mechanism 42.

[0084] The implementation method of Example 5 is as follows:

[0085] Based on Example 2, Example 5 further includes the following implementation: The movable telescopic rod 31 includes a hollow connecting sleeve rod 311 located on the side away from the fixed connecting rod 32. The rotating mechanism 5 includes a mounting part 51 located on the lamp head assembly 2, a mounting through hole 52 located on the side of the connecting sleeve rod 311 near the lamp head assembly 2, and a fixing mechanism 53 located between the mounting part 51 and the mounting through hole 52. The mounting part 51 extends into the mounting through hole 52 and is rotatably connected to the connecting sleeve rod 311 through the fixing mechanism 53. A fixing space for clamping the connecting sleeve rod 311 is formed between the mounting part 51 and the fixing mechanism 53.

[0086] The implementation method of Example 6 is as follows:

[0087] Based on Embodiment 5, Embodiment 6 further includes the following implementation: The mounting part 51 includes an extension shaft 511 extending toward the mounting through hole 52, and the fixing mechanism 53 includes a limiting nut 531, an elastic clamping member 532, and a washer 533. The limiting nut 531, the elastic clamping member 532, and the washer 533 are all sleeved on the outer side wall of the extension shaft 511 and are arranged vertically along the height direction of the extension shaft 511.

[0088] The implementation method of Example 7 is as follows:

[0089] Based on Example 5, Example 7 also has the following implementation method: the connecting sleeve rod 311 and the fixed connecting rod 32 are the same size.
