[0029] like Figures 1 to 3As shown, this embodiment of the utility model provides a telescopic rod assembly 10, including a first rod 11, a second rod 12, a connecting seat 13, and a locking member 14. The first rod 11 has an axially extending cavity 111, which penetrates at least one end of the first rod 11 along the axial direction, and a first through hole 112 is formed on the side wall of the first rod 11. At least a portion of the second rod 12 passes through the cavity 111 and can reciprocate relative to the first rod 11. At least a portion of the connecting seat 13 is located in the cavity 111 and is connected to the first rod 11, and a second through hole 131 communicating with the cavity 111 is formed on the connecting seat 13. The locking member 14 passes through the first through hole 112 and is inserted into the second through hole 131, and is movably connected to the connecting seat 13 to abut against the second rod 12. The locking member 14 can abut against any part of the side wall of the second rod 12 through the second through hole 131 to lock the position of the second rod 12 relative to the first rod 11.

[0030] Specifically, the axial direction of the first rod 11 refers to the direction from one end of the first rod 11 to the other, which can also be understood as the length direction of the first rod 11. The cavity 111 formed on the first rod 11 extends axially through at least one end of the first rod 11, creating an opening at at least one end of the first rod 11 into which the second rod 12 can pass. It is understood that the cross-sectional dimensions of both the first rod 11 and the cavity 111 in the horizontal direction (perpendicular to the axial direction) are larger than the cross-sectional dimensions of the second rod 12 in the horizontal direction, to ensure that the second rod 12 can smoothly pass into the cavity 111 and reciprocate axially relative to the first rod 11. It is understood that the axial direction of the second rod 12 is parallel or coincident with the axial direction of the first rod 11. Of course, under the premise of smooth sliding, a certain positional deviation is also allowed, resulting in non-parallelism or non-coincidence.

[0031] The connecting seat 13 is typically positioned near the first through hole 112 and connected to the first rod 11. At least a portion of the connecting seat 13 is located within the cavity 111, such that the second through hole 131 of the connecting seat 13 communicates with the cavity 111. For example, the connecting seat 13 may be partially located within the cavity 111, with the other portion extending out of the first rod 11 via the first through hole 112; alternatively, the connecting seat 13 may be entirely located within the cavity 111, with one end of the second through hole 131 communicating with the first through hole 112 and the other end communicating with the cavity 111. Optionally, the connection between the connecting seat 13 and the first rod 11 can be achieved through non-removable methods such as bonding or welding, or through detachable methods such as threaded connections or snap-fit ​​connections, as long as the requirement of a stable and reliable connection is met.

[0032] The locking member 14 passes through the second through hole 131 on the connecting seat 13. One end of the locking member 14 extends from the end of the second through hole 131 that connects to the cavity 111, so as to abut against the second rod 12. Under the action of the abutment force, the position of the second rod 12 relative to the first rod 11 is locked. Furthermore, the locking member 14 is movably connected to the connecting seat 13, and the relative position of the locking member 14 and the connecting seat 13 can be adjusted as needed, so that the locking member 14 can switch between pressing and locking the second rod 12 and releasing the second rod 12. When the locking member 14 releases the second rod 12, the length of the second rod 12 extending from the first rod 11 can be adjusted. After the adjustment is completed, the locking member 14 abuts against the second rod 12 and presses the second rod 12, so that a large frictional force is generated between the locking member 14 and the second rod 12, which can restrict the extension and retraction of the second rod 12 and realize the position locking of the second rod 12.

[0033] Specifically, to achieve the movable connection between the locking member 14 and the connecting seat 13, in one embodiment, the locking member 14 can be configured as a spring, with one end fixed to the connecting seat 13 and the other end movable relative to the connecting seat 13, passing through the second through hole 131 and abutting against the second rod 12. When the spring abuts against the second rod 12, the spring is in a compressed state, thereby continuously applying an elastic force to the second rod 12, pressing the second rod 12 tightly, thus keeping the second rod 12 stable in position when not subjected to external force, and preventing it from loosening. When it is necessary to adjust the extension length of the second rod 12, the friction between the spring and the second rod 12 can be overcome by applying external force, causing the second rod 12 to extend or retract. With this design, when the second rod 12 completes the extension and retraction adjustment and the external force is removed, the friction between the spring and the second rod 12 can automatically stop the movement of the second rod 12 and keep it in the adjusted position. During the adjustment process, there is no need to operate the locking member 14, making the adjustment operation simple and convenient. Of course, the spring in the above solution can also be replaced with a spring sheet, rubber damping block, or other components that can apply elastic force. In addition to the above solution, the movable connection between the locking member 14 and the connecting seat 13 can also be a threaded connection, which will be described in detail in the following embodiments.

[0034] It should be noted that the locking member 14 can abut against any part of the side wall of the second rod 12. The term "any part of the side wall" means at least any position of the side wall extending axially. In other words, the locking member 14 can abut against at least any position of the side wall of the second rod 12 extending axially, and is not limited to a specific preset position. This allows the second rod 12 to be freely extended and retracted in the axial direction and locked after adjustment.

[0035] The telescopic rod assembly 10 provided in this embodiment includes a first rod 11, a second rod 12, a connecting seat 13, and a locking member 14. A cavity 111 extending axially is formed in the first rod 11, allowing the second rod 12 to pass through the cavity 111 and reciprocate relative to the first rod 11, adjusting the length of the second rod 12 extending beyond the first rod 11. A first through hole 112 is formed on the side wall of the first rod 11, and a second through hole 131 communicating with the cavity 111 is formed in the connecting seat 13. The locking member 14 passes through the first through hole 112 and is movably connected to the connecting seat 13, allowing it to abut against any part of the side wall of the second rod 12 to lock the position of the second rod 12. This design allows for free adjustment of the length of the second rod 12 extending beyond the first rod 11. The second rod 12 can be locked at any extension length within a preset range (e.g., within the length of the first rod 11, ensuring the second rod 12 does not detach from the first rod 11), rather than being limited to a preset locking position. This achieves stepless adjustment and significantly improves the flexibility of adjustment. Furthermore, since the contact position between the locking member 14 and the second rod 12 is not limited to a specific location, a connection structure compatible with the locking member 14 is typically not required on the side wall of the second rod 12. This simplifies the structure of the second rod 12 and helps reduce the structural complexity of the telescopic rod assembly 10.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the connecting seat 13 includes a first connecting member 132 and a second connecting member 133. The first connecting member 132 is inserted into the first through hole 112. One end of the first connecting member 132 located within the cavity 111 has an abutment portion 1321, the area of ​​which is larger than the area of ​​the first through hole 112. The abutment portion 1321 abuts against the side wall of the first rod 11. The second connecting member 133 is connected to the end of the first connecting member 132 located outside the first rod 11 and is connected to the first rod 11. The second through hole 131 is formed on the first connecting member 132.

[0037] Specifically, the "area" of both the abutment portion 1321 and the first through hole 112 refers to the projected area along the direction in which the abutment portion 1321 abuts against the side wall of the first rod 11, or it can be understood as the projected area along the opening direction of the first through hole 112. By making the area of ​​the abutment portion 1321 larger than the area of ​​the first through hole 112, it is ensured that the abutment portion 1321 will not pass through the first through hole 112 when it abuts against the side wall of the first rod 11. With this arrangement, one end of the first connector 132 located inside the cavity 111 abuts against the first rod 11 through the abutment portion 1321, and the other end of the first connector 132 extending outside the first rod 11 is connected to the first rod 11 through the second connector 133, thus achieving the connection and fixation between the connecting seat 13 as a whole and the first rod 11.

[0038] Optionally, the abutment portion 1321 and the side wall of the first rod 11 may simply abut against each other, or they may be further fixed together using fasteners such as screws, or other connection methods such as bonding or snap-fitting. This arrangement allows the abutment portion 1321 and the first rod 11 to form a more stable connection, improving structural reliability. When the abutment portion 1321 and the side wall of the first rod 11 only abut against each other, the assembly operation can be simplified, and the second connector 133 can also reliably fix the first connector 132 and the first rod 11.

[0039] In one possible embodiment, the first connector 132 and the second connector 133 are both independent components, requiring assembly connection to the first rod 11, rather than being integrally formed with the first rod 11. The second connector 133 can typically be detachably connected to the first connector 132 and abut against the first rod 11. This allows the abutting portion 1321 and the second connector 133 to abut against the inner and outer sides of the first rod 11, respectively, forming a clamping effect on the first connector 132. This effectively prevents the first connector 132 from loosening and secures it to the first rod 11. Furthermore, with this connection method, the first rod 11 only needs the first through hole 112; no other connecting structures are required, simplifying the structure of the first rod 11 and improving its production efficiency.

[0040] In one embodiment of the above-described connection method, the second connector 133 can be a retaining ring, and the end of the first connector 132 extending outside the first rod 11 has a corresponding retaining groove. A retaining ring is inserted into the groove using retaining ring pliers or similar tools. Thus, by the retaining ring abutting against the outer sidewall of the first rod 11, and the abutting portion 1321 abutting against the inner sidewall of the first rod 11, a clamping effect is formed on the first connector 132, preventing it from loosening along the opening direction of the first through hole 112. Besides the above solution, the connection between the second connector 133 and the first connector 132 can also be a threaded connection, as detailed in the following embodiments.

[0041] In the above embodiment, a first connector 132 is inserted into the first through hole 112. One end of the first connector 132 located inside the cavity 111 abuts against the side wall of the first rod 11 via an abutment portion 1321, and the other end of the first connector 132 located outside the first rod 11 is connected to the first rod 11 via a second connector 133, thereby achieving a reliable connection between the connecting seat 13 and the first rod 11. By adopting the above design, there is no need to set up a complex connection structure on the first rod 11 to adapt to the installation of the connecting seat 13, which helps to simplify the structure of the first rod 11, improve the production efficiency of the first rod 11, and reduce the number of assembly steps for the first connector 132 and the second connector 133, thus reducing the assembly difficulty.

[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the locking member 14 is provided with a first external thread 141, and the first connecting member 132 is provided with a first internal thread 1311 on the inner wall of the second through hole 131. The first external thread 141 and the first internal thread 1311 are engaged and connected. Specifically, the movable connection between the locking member 14 and the first connecting member 132 is a threaded connection. When the first external thread 141 on the locking member 14 is aligned with the position of the second through hole 131, and the locking member 14 rotates relative to the first connecting member 132, the first external thread 141 engages with the first internal thread 1311 in the second through hole 131, which guides the locking member 14 to move along the opening direction of the second through hole 131, so that the locking member 14 passes through the second through hole 131 and abuts against the second rod body 12.

[0043] Optionally, the locking member 14 may be provided with an operating part, which may specifically be a knob, handle, or other structure suitable for hand operation, for example... Figure 2The locking member 14 shown is equipped with a knob structure. With this design, the user can rotate the locking member 14 by grasping the operating part on the locking member 14, thereby rotating the locking member 14 as a whole. This causes the first external thread 141 on the locking member 14 to engage with the first internal thread 1311 in the second through hole 131, thus realizing the installation of the locking member 14 and the first connecting member 132, or adjusting the tightness of the compression between the locking member 14 and the second rod 12. Moreover, the above operations can be completed by hand without the aid of tools, making the operation convenient.

[0044] In the above embodiments, the locking member 14 is connected to the first internal thread 1311 on the locking member 14 by engaging with the first internal thread 1311 on the first connecting member 132, thereby achieving a reliable connection and fixation between the locking member 14 and the first connecting member 132. Furthermore, by rotating the locking member 14, the tightness of the compression between the locking member 14 and the second rod 12 can be easily adjusted. When the locking member 14 is released from the second rod 12, it is convenient to perform telescopic adjustment. When the locking member 14 is pressed tightly against the second rod 12, it can achieve a stable position lock.

[0045] In some embodiments, such as Figure 3 and Figure 4 As shown, the second connector 133 has a connecting hole 1331, and one end of the first connector 132 located outside the first rod 11 is inserted into the connecting hole 1331. The end of the first connector 132 located outside the first rod 11 is provided with a second external thread 1322, and the inner wall of the second connector 133 forming the connecting hole 1331 is provided with a second internal thread 1332. The second external thread 1322 and the second internal thread 1332 are engaged and connected.

[0046] Specifically, the second connector 133 is connected to the first connector 132 by a threaded connection. After the second external thread 1322 and the second internal thread 1332 are engaged, the end of the second connector 133 facing the first rod 11 abuts against the outer wall of the first rod 11, while the abutting portion 1321 formed by the first connector 132 abuts against the inner wall of the first rod 11, thus clamping and fixing the first connector 132 onto the first rod 11. Optionally, the second connector 133 can directly use a standard nut that meets the requirements, thus eliminating the need to separately machine the connecting hole 1331 and the second internal thread 1332, thereby simplifying the production process and improving production efficiency.

[0047] In some possible implementations, to improve the stability of the connection between the second connector 133 and the first connector 132, an elastic structure, such as a spring sheet, can be provided between the second connector 133 and the first rod 11, so that the second connector 133 abuts against the first rod 11 via the spring sheet. In this way, the elastic force generated by the compression of the spring sheet makes the second external thread 1322 and the second internal thread 1332 press tightly against each other, increasing the friction between the threads, which can effectively prevent the connection from loosening and ensure that the connection between the second connector 133 and the first connector 132 is stable and reliable.

[0048] In the above embodiment, a connecting hole 1331 is opened on the second connector 133, a second internal thread 1332 is provided on the inner wall of the connecting hole 1331, and a second external thread 1322 is provided on the first connector 132. By making the second external thread 1322 and the second internal thread 1332 cooperate and connect, the locking member 14 and the first connector 132 are reliably fixed. Moreover, the structure is simple and the assembly operation is convenient.

[0049] In some embodiments, such as Figure 3 and Figure 5 As shown, the telescopic rod assembly 10 also includes a connecting sleeve 15. The connecting sleeve 15 is installed at the end of the first rod 11 through which the second rod 12 passes, and the second rod 12 is movably inserted into the connecting sleeve 15. The connecting sleeve 15 is provided with a first limiting part 151, and the portion of the second rod 12 located in the cavity 111 is provided with a second limiting part 121. The second limiting part 121 is used to abut against the first limiting part 151 to limit the relative movement range between the second rod 12 and the first rod 11.

[0050] Specifically, the connecting sleeve 15 is typically inserted into the cavity 111 at one end of the first rod 11 through which the second rod 12 passes, rather than being sleeved on the outside of the first rod 11, so that at least the first limiting part 151 provided on the connecting sleeve 15 is located within the cavity 111. Furthermore, the inner cavity of the connecting sleeve 15 extends through both opposite ends of the connecting sleeve 15, allowing the second rod 12 to pass through the connecting sleeve 15, with both ends of the second rod 12 extending out through both ends of the connecting sleeve 15. When assembling the connecting sleeve 15, it is generally possible to first insert one end of the second rod 12 with the second limiting part 121 into the cavity 111, then sleeve the connecting sleeve 15 onto the other end of the second rod 12, allowing the connecting sleeve 15 to move axially along the second rod 12 towards the first rod 11, and finally install the connecting sleeve 15 onto the end of the first rod 11 through which the second rod 12 passes. The above assembly steps are clear and easy to implement.

[0051] The above embodiment employs a connecting sleeve 15 at the end of the first rod 11 through which the second rod 12 passes, and a first limiting part 151 on the connecting sleeve 15, and a second limiting part 121 on the portion of the second rod 12 located within the cavity 111. With this configuration, when the second rod 12 extends outward relative to the first rod 11, the second limiting part 121 gradually approaches the connecting sleeve 15 until it abuts against the first limiting part 151, indicating that the extension length of the second rod 12 has reached the maximum preset length. Thus, the blocking effect of the first limiting part 151 restricts further extension of the second rod 12, preventing the second rod 12 from over-extending and detaching from the first rod 11.

[0052] In some embodiments, such as Figures 1 to 3 As shown, the connecting sleeve 15 is provided with a first locking part 152, and the first rod 11 is provided with a second locking part 113 corresponding to the first locking part 152. The first locking part 152 and the second locking part 113 are locked together.

[0053] Optionally, such as Figure 2 As shown, the first latching portion 152 can be a snap fastener, and the second latching portion 113 is a snap-fit ​​hole adapted to the snap fastener. Alternatively, the first latching portion 152 can also be a snap-fit ​​hole, and the second latching portion 113 can be a snap fastener adapted to the snap-fit ​​hole. Furthermore, one or more of the first latching portion 152 and the second latching portion 113 can be provided corresponding to each other, for example, as... Figure 1 As shown, a plurality of second snap-fit ​​parts 113 are provided on the side wall of the first rod body 11, and a plurality of first snap-fit ​​parts 152 are also provided on the connecting sleeve 15, so that each first snap-fit ​​part 152 and each second snap-fit ​​part 113 are snapped together one by one. This arrangement can increase the stability of the connection between the connecting sleeve 15 and the first rod body 11.

[0054] The above embodiment adopts a first snap-fit ​​part 152 on the connecting sleeve 15 and a second snap-fit ​​part 113 on the first rod body 11. The first snap-fit ​​part 152 and the second snap-fit ​​part 113 are snapped together to achieve a reliable connection between the connecting sleeve 15 and the first rod body 11. Furthermore, this connection method is easy to install and disassemble and convenient to operate.

[0055] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, one end of the connecting sleeve 15 along the axial direction is inserted into the cavity 111, and a third through hole 153 is formed on the side wall of the connecting sleeve 15 within the cavity 111. The third through hole 153 communicates with the first through hole 112, and one end of the connecting seat 13 located within the cavity 111 is connected to the connecting sleeve 15. The other end of the connecting seat 13 is located within the third through hole 153, or within the first through hole 112, or extends out of the first rod body 11.

[0056] Specifically, in the scheme with the connecting sleeve 15, since the connecting sleeve 15 is connected to the first rod 11, the connecting seat 13 can be connected to the connecting sleeve 15, thereby achieving an indirect connection with the first rod 11. To prevent the connecting sleeve 15 from obstructing the first through hole 112 opened in the first rod 11, a third through hole 153 can be opened on the connecting sleeve 15 and connected to the first through hole 112. In this way, when one end of the connecting seat 13 is connected to the connecting sleeve 15, the second through hole 131 opened on the connecting seat 13 communicates with the outside of the first rod 11 through the space formed by the first through hole 112 and the third through hole 153.

[0057] Optionally, when the connecting seat 13 includes a first connecting member 132 and a second connecting member 133, the abutting portion 1321 formed by the first connecting member 132 can be connected to the connecting sleeve 15, and the area of ​​the abutting portion 1321 can be larger than the area of ​​the third through hole 153, so that the abutting portion 1321 abuts against the side wall of the connecting sleeve 15 located in the cavity 111, without passing through the third through hole 153. The first connecting member 132 extends out of the outside of the first rod body 11 through the third through hole 153 and the first through hole 112 in sequence, and is connected to the first rod body 11 through the second connecting member 133, thereby realizing the connection and fixation of the connecting seat 13, the connecting sleeve 15 and the first rod body 11.

[0058] In the above embodiments, by opening a third through hole 153 on the connecting sleeve 15 and connecting the third through hole 153 to the first through hole 112, the connecting seat 13 can be indirectly connected to the first rod 11 by connecting to the connecting sleeve 15. This arrangement ensures that the connection between the connecting seat 13 and the first rod 11 is still achieved even with the connecting sleeve 15, avoiding interference between the connecting sleeve 15 and the connecting seat 13, and resulting in a reasonable structural arrangement. Furthermore, since the portion of the connecting seat 13 located within the cavity 111 is directly connected to the connecting sleeve 15, it does not need to directly contact the inner wall of the first rod 11. This allows the connecting sleeve 15 to act as a buffer, reducing the squeezing effect of the connecting seat 13 on the first rod 11, thereby reducing the squeezing deformation and wear caused to the first rod 11.

[0059] In some embodiments, such as Figure 3 and Figure 5 As shown, the connecting sleeve 15 has a receiving groove 154 on its side wall inside the cavity 111, the connecting seat 13 is at least partially located in the receiving groove 154, and the third through hole 153 is located in the receiving groove 154.

[0060] Specifically, the receiving groove 154 is typically formed in the inner side wall of the connecting sleeve 15, that is, in the side wall of the connecting sleeve 15, on the side connected to the connecting seat 13. The shape of the receiving groove 154 can be designed according to the shape of the end of the connecting seat 13 connected to the connecting sleeve 15 or according to the shape of the abutment part 1321, and ensure that the receiving groove 154 has sufficient depth to at least satisfy that the end of the connecting seat 13 connected to the connecting sleeve 15 is set in the receiving groove 154 without protruding from the inner wall of the connecting sleeve 15, thereby avoiding interference with the telescopic movement of the second rod 12. Furthermore, by positioning the third through hole 153 in the receiving groove 154, it is possible to satisfy that one end of the connecting seat 13 is set in the receiving groove 154, and the other end can extend toward the third through hole 153, so that the second through hole 131 opened on the connecting seat 13 communicates with the outside of the first rod 11. Optionally, when the connector 13 includes the first connector 132 and the second connector 133 described above, the shape of the receiving groove 154 can be adapted to the shape of the abutment portion 1321 so that the abutment portion 1321 is disposed in the receiving groove 154.

[0061] The above embodiment employs a receiving groove 154 on the side wall of the connecting sleeve 15, so that the connecting seat 13 is at least partially located in the receiving groove 154. This reduces the space occupied by the connecting seat 13 in the cavity 111 when the connecting sleeve 15 is provided, improves the structural compactness, and can better prevent the connecting seat 13 from protruding out of the connecting sleeve 15 and interfering with the telescopic movement of the second rod 12, thereby ensuring the smooth movement of the second rod 12.

[0062] In some embodiments, such as Figures 1 to 3 As shown, the end of the connecting sleeve 15 away from the cavity 111 is provided with a flange 155, which overlaps the end face of the first rod 11, and the surface of the flange 155 is a smooth curved surface.

[0063] Optionally, the flange 155 can be formed into a smooth curved surface by direct molding, or the sharp edges on the flange 155 can be removed by rounding the corners. When the connecting sleeve 15 is provided with a first locking part 152 and the second rod 12 is provided with a second locking part 113, the positions of the first locking part 152 and the second locking part 113 can be reasonably designed so that when the flange 155 overlaps the end face of the first rod 11, the first locking part 152 and the second locking part 113 can be locked together, thereby realizing the connection positioning and fixation of the connecting sleeve 15.

[0064] The above embodiment employs a flange 155 at the end of the connecting sleeve 15 facing away from the cavity 111, allowing the flange 155 to overlap the end face of the first rod 11, thus reliably positioning the connecting sleeve 15. Simultaneously, by making the surface of the flange 155 a smooth curved surface, the flange 155 covers the end face of the first rod 11, preventing sharp edges from causing scratches and improving safety.

[0065] In some embodiments, such as Figure 3 As shown, the telescopic rod assembly 10 also includes a guide wheel 16, which is movably connected to the side wall of the second rod 12. The guide wheel 16 can abut against the side wall of the first rod 11 to guide the second rod 12 to move axially. Optionally, the guide wheel 16 can be cylindrical, spherical, or other shapes that facilitate rolling on the side wall of the first rod 11, and multiple guide wheels 16 can be provided. Each guide wheel 16 can be arranged axially on the second rod 12 or circumferentially (perpendicular to the axial direction) on the second rod 12, providing a flexible design.

[0066] In the above embodiment, a guide wheel 16 is movably connected to the side wall of the second rod 12. When the second rod 12 is extended or retracted relative to the first rod 11, the guide wheel 16 abuts against the side wall of the first rod 11, which reduces the swaying of the second rod 12 and improves the smoothness of the axial extension and retraction of the second rod 12. Furthermore, the guide wheel 16 can roll along the side wall of the first rod 11 to drive the second rod 12 to extend or retract axially. Since the rolling friction is small, the smoothness of the movement can be improved.

[0067] Optionally, when a connecting sleeve 15 is provided, and a first limiting part 151 is provided on the connecting sleeve 15, then the guide wheel 16, which is closest to the first limiting part 151, can serve as a second limiting part 121, such as... Figure 2 As shown, with this configuration, the guide wheel 16 serves both as a limiter and a guide, eliminating the need for a separate limiter structure on the second rod 12, which simplifies the structure.

[0068] like Figure 6 As shown, this utility model embodiment also provides a lamp 20, including a base 21, a lamp head 22 and the above-mentioned telescopic rod assembly 10, wherein one of the first rod body 11 and the second rod body 12 is connected to the base 21 and the other is connected to the lamp head 22.

[0069] The lamp 20 provided in this embodiment of the present invention, by employing the aforementioned telescopic rod assembly 10, allows the second rod 12 to reciprocate relative to the first rod 11. Furthermore, the locking member 14 enables the second rod 12 to be locked in position within a preset range of any extended length, thereby allowing for stepless adjustment of the distance between the lamp head 22 and the base 21, meeting the usage requirements of different lighting heights for the lamp head 22. Simultaneously, the height adjustment of the lamp head 22 offers high flexibility and is convenient to use.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
