[0053] The following refers to the appendix to the specification of this invention. Figure 1 To be continued Figure 11C The tool lamp of the present invention will be described in detail.

[0054] This invention provides a tool lamp comprising at least one power supply unit 10 and at least one lamp body unit 20. The power supply unit 10 is electrically connected to the lamp body unit 20, and the power supply unit 10 provides electrical energy to the lamp body unit 20 to enable it to emit light. The tool lamp provided by this invention, as a lighting device, is not only easy to carry, store, and use, but is also not limited to any particular application environment.

[0055] Furthermore, the tool lamp also includes at least one connecting unit 30, and the lamp body unit 20 is detachably installed on the connecting unit 30. The connecting unit 30 is used to connect the lamp body unit 20 so that the lamp body units 20 are connected in series. By changing the number of lamp body units 20, the overall length of the detachable tool lamp is changed, thereby changing the illumination range of the tool lamp according to the needs of different usage environments.

[0056] In this invention, the number of lamp body units 20 can be one, two or more. Those skilled in the art will understand that the number of lamp body units 20 and the number of connecting units 30 are not limited.

[0057] For example, when there is one lamp unit 20, the lamp unit 20 is installed on the power supply unit 10. By controlling the power supply unit 10, the lamp unit 20 can be controlled to emit light to meet the lighting needs. When there are two lamp units 20, a connecting unit 30 needs to be set between the two lamp units 20 so that the two lamp units 20 are connected in series. By controlling the power supply unit 10, the two lamp units can be controlled to emit light to meet the lighting needs. When there are three or more lamp units 20, a connecting unit 30 is provided between each pair of adjacent lamp units 20 so that the lamp units 20 and the connecting units 30 are alternately connected. By controlling the power supply unit 10, three or more lamp units can be controlled to emit light to meet the lighting needs.

[0058] In summary, depending on the needs of the illumination environment, an appropriate number of the lamp body units 20 can be selected. For example, when the illumination environment is small, the tool lamp can be adjusted to one lamp body unit, and when the illumination environment is large, the tool lamp can be adjusted to two or more lamp body units.

[0059] It is worth mentioning that when the connecting unit 30 connects each of the lamp body units 20 together in series, the power supply unit 10, the lamp body unit 20 and the connecting unit 30 are electrically connected together. By controlling the power supply unit 10, the lamp body unit can be controlled to emit light 20 to meet the lighting needs.

[0060] Furthermore, the tool lamp also includes at least one hook-lock unit 40, which is disposed at the end of the power supply unit 10. The hook-lock unit 40 can be rotated and stretched. By stretching the hook-lock unit 40, the tool lamp can be suspended or fixed to an object for convenient use.

[0061] As attached Figure 2 To be continued Figure 11C A preferred tool lamp of the present invention is shown, such as Figure 3 As shown, the tool lamp includes two power supply units 10, three lamp body units 20, and two connecting units 30. The power supply units 10 are fixedly disposed at both ends of the tool lamp, and the lamp body units 20 and the connecting units 30 are arranged alternately to form a tool lamp with three light-emitting units.

[0062] The power supply unit 10 includes a first power supply unit 11 and a second power supply unit 12; the lamp body unit 20 includes a first lamp body unit 21, a second lamp body unit 22 and a third lamp body unit 23; and the connection unit 30 includes a first connection unit 31 and a second connection assembly unit 31.

[0063] Preferably, in this embodiment of the present invention, the first lamp body unit 21, the second lamp body unit 22, and the third lamp body unit 23 have roughly the same structure and function; the first connecting unit 31 and the second connecting unit 32 have roughly the same structure and function; the first power supply unit 11 and the second power supply unit 12 have roughly the same structure and function. In the following description, only a part of them will be described, and the others will not be repeated.

[0064] Wherein, one end of the first lamp body unit 21 is installed on the first power supply unit 11, the other end of the first lamp body unit 21 is connected to one end of the first connecting unit 31, the other end of the first connecting unit 31 is connected to one end of the second lamp body unit 22, the other end of the second lamp body unit 22 is installed on one end of the second connecting unit 32, the other end of the second connecting unit 32 is connected to one end of the third lamp body unit 23, and the other end of the third lamp body unit 23 is installed on the second power supply unit 12.

[0065] In short, the power supply unit 10 is disposed at both ends of the tool lamp, and the lamp body unit 20 and the connection unit 30 are disposed alternately in sequence. That is, the first power supply unit 11, the first lamp body unit 21, the first connection unit 31, the second lamp body unit 22, the second connection unit 32, the third lamp body unit 23, and the second power supply unit 12 are electrically connected together in sequence to form the tool lamp. By controlling the first power supply unit 11 or the second power supply unit 12, the entire circuit can be controlled, thereby controlling the first lamp body unit 21, the second lamp body unit 22, and the third lamp body unit 23 to emit light and achieve the function of illumination.

[0066] The first lamp body unit 21 is detachable from the first connecting unit 21, and the third lamp body unit 23 is detachable from the second connecting unit 32, so as to change the number of light-emitting units of the tool lamp, thereby changing the illumination range or illumination area of ​​the tool lamp.

[0067] Furthermore, such as Figures 5 to 7 As shown, the tool lamp also includes a plug-in unit 50. The plug-in unit 50 is disposed at one end 32 where the first lamp body unit 21 or the third lamp body unit 23 is connected to the first connecting unit 31 and the second connecting unit. The plug-in unit 50 is used to electrically connect the first lamp body unit 21 and the third lamp body unit 23 to the first connecting unit 31 and the second connecting unit 32. Through the plug-in unit 50, the first lamp body unit 21 and the third lamp body unit 23 can be detachably installed to the first connecting unit 31 and the second connecting unit 32.

[0068] Specifically, the plug-in unit 50 includes a plug-in portion 51, a fixing portion 52, a fixing device 53, an elastic element 54, and two buttons 55, such as... Figures 5 to 7As shown, the plug-in part 51 and the fixing part 52 are two integrally connected upper and lower parts. The plug-in part 51 is detachably inserted into the connecting unit 30, and the lamp body unit 20 is fixed to the connecting unit 30 by the button 55. The fixing part 52 can be sleeved on the end of the lamp body unit 20 and fix the plug-in part 50 to the end of the lamp body unit 20. Preferably, the fixing part 52 fixes the plug-in part 50 to the end of the lamp body unit 20 by screws or rivets.

[0069] Furthermore, the plug-in part 51 is a hollow cuboid structure. A row of electrical connection holes 511 is provided at the middle position of the top of the cuboid structure, and two fixing holes 512 are provided opposite to each other at the middle position of the two sides of the top. Two locking holes 513 are provided at the middle position of the two side walls respectively. The interior of the plug-in part 51 is used to accommodate the fixing device 53.

[0070] Specifically, the fixing device 53 has a receiving cavity 531 for the elastic member 54 to extend and retract, and its opposite side walls each have an extension hole 532. Preferably, the button 55 has a front end 551, a rear end 552 and a protruding end 553, wherein the front end of the button 55 passes through the extension hole 532, and the rear end 552 is connected to the elastic member 54. When the front end of the button 55 is pressed at the same time, the elastic member 54 can extend and retract within the fixing device 53.

[0071] When the fixing device 53 is placed inside the plug-in portion 51, the telescopic holes 532 on both sides of the fixing device 53 are exactly opposite to the locking holes 513 on both sides of the plug-in portion 51. At this time, the front end 551 of the button protrudes through the locking hole 513 of the plug-in portion 51. Since the area of ​​the protruding end 553 of the button is larger than the area of ​​the locking hole 513, only the front end of the button 55 can protrude outside the locking hole 513. When the fixing device 53 is placed inside the plug-in portion 51 and the front end of the button 55 is pressed, the elastic member 54 continues to reciprocate within the fixing device 53, thereby causing the button 55 to reciprocate.

[0072] In this embodiment, the fixing device 53 is fixed to the plug-in portion 51 by screws. That is, the side wall of the fixing device 53 is provided with two threaded holes 533, which are aligned with the fixing hole 512 on the top of the plug-in portion 51. The fixing device 53 is installed into the interior of the plug-in portion 51 by screws.

[0073] Preferably, in this embodiment, the elastic element 54 is a spring.

[0074] Furthermore, each of the two arms of the connecting unit 30 has a button hole 301. When the plug part 51 is inserted into the connecting unit 30, the front end 551 of the button can just protrude from the button hole 301. At this time, the lamp body unit 20 is fixedly connected to the connecting unit 30. When the button 55 is pressed at the same time, the plug part 51 can be removed from the connecting unit 30, thereby realizing the detachable installation of the lamp body unit 20 and the connecting unit 30.

[0075] It is worth mentioning that the front end 551 of the button has a bevel to facilitate the removal or insertion of the button 55 from the button hole 301 during disassembly.

[0076] For example, when the first lamp body unit 21 is detached from the first connecting unit 31, the first power supply unit 11 and the first lamp body unit 21 form a complete tool lamp. By controlling the first power supply unit 10, the first lamp body unit 21 can be controlled to achieve the lighting function. The second power supply unit 112, the second lamp body unit 22, and the third lamp body unit 23 form a complete tool lamp. By controlling the second power supply unit 12, the second lamp body unit 22 and the third lamp body unit 23 can be controlled to achieve the lighting function. Alternatively, when the third lamp body unit 23 is detached from the second connecting unit 32, the second power supply unit 12 and the third lamp body unit 23 form a complete tool lamp. By controlling the second power supply unit 12, the third lamp body unit 23 can be controlled to achieve the lighting function. The first power supply unit 11, the first lamp body unit 21, and the second lamp body unit 22 form a complete tool lamp. By controlling the second power supply unit 12, the first lamp body unit 21 and the second lamp body unit 22 can be controlled to achieve the lighting function.

[0077] When the first lamp body unit 21 and the third lamp body unit 23 are detached from the first connecting unit 31 and the second connecting unit 32 respectively, the first power supply unit 31 and the first lamp body unit 21 form a complete tool lamp assembly, and the second power supply unit 12 and the third lamp body unit 23 form a complete tool lamp assembly. By controlling the first power supply unit 11, the first lamp body unit 21 can be controlled to achieve the lighting function, and by controlling the second power supply unit 12, the third lamp body unit 23 can be controlled to achieve the lighting function. That is, the tool lamp is disassembled into two independent parts, which are hooked to the car window position by the hook-lock unit 40, and each part can achieve lighting independently.

[0078] In summary, when the lamp body units 20 are connected together through the connecting unit 30, they can form a relatively long tool lamp. When the lamp body units 20 are detached from the connecting unit 30, the lamp body units 20 can also form a tool lamp on their own. In use, the tool lamp can be disassembled into different parts according to actual needs. Therefore, the tool lamp is more flexible and convenient to use.

[0079] like Figure 8A and 8B As shown, the connection unit includes a first rotating unit 302, a second rotating unit 303, a braking element 304, a reset element 305, and a push button 306.

[0080] The first rotating unit 302 has a first rotating space 3021, and the second rotating unit 303 has a second rotating space 3031. Both the first rotating space 3021 and the second rotating space 3031 are circular spaces, and are arranged opposite to each other to form a connected space. The first rotating unit 302 has a first rotating shaft 3022, and the second rotating unit 303 has a second rotating shaft 3023. Shaft 3032, the first rotating shaft 3022 and the second rotating shaft 3032 are both located at the center of the rotating unit, and the first rotating shaft 3022 and the first rotating unit 302 are integrally formed, and the second rotating shaft 3032 and the second rotating unit 303 are integrally formed. The first rotating shaft 3022 and the second rotating shaft 3032 are coaxially arranged, and the first rotating shaft 3022 can be sleeved on the outside of the second rotating shaft 3032 so that the first rotating unit 302 is coupled to the second rotating unit 303.

[0081] Furthermore, the braking element 304 is disposed in the space where the first rotation space 3021 and the second rotation space 3031 are connected, and the braking element 304 can move within the space where the first rotation space 3021 and the second rotation space 3031 are connected. By controlling the position of the braking element 304, the rotation state of the connecting unit 30 can be controlled, whether the connecting unit 30 is in a rotating state or a non-rotating state.

[0082] Furthermore, the push button 306 is located on the outside of the first rotating unit 302, adjacent to the braking element, and the reset element is located in the second rotating space. By pressing the push button 306, the position of the braking element 304 in the communicating space can be controlled.

[0083] Specifically, when the braking element 304 is located in the first rotation space 3021 or the second rotation space 3031, the braking element 304 can rotate with the first rotation unit 302 or the second rotation unit 303, and the connecting unit 30 is in a rotatable state; when the braking element 304 is located between the first rotation space 3021 and the second rotation space 3031, the braking element 304 prevents the first rotation unit 302 and the second rotation unit 303 from rotating relative to each other, and the connecting unit is in a non-rotatable state.

[0084] like Figure 3 As shown, since the connecting unit 30 has a rotation function, when the lamp body unit 20 is installed on the connecting unit 30, the lamp body unit 20 can rotate based on the connecting unit 30, so that the lamp body unit 20 has different unfolded states. Specifically, when two lamp body units 20 connected to the same connecting unit 30 are flipped around the connecting unit 30 as an axis, a certain rotation angle will be formed between the two lamp body units 20. Preferably, the rotation angle is between 0° and 180°. By controlling the rotation angle, the position of the lamp body unit 20 can be controlled, such as... Figure 1 It can be seen that when the rotation angle is 180°, the tool lamp is in a straight line and in its fully extended state. At this time, the tool lamp has the longest illumination range; for example... Figure 4 It can be seen that when the rotation angle is 0°, the two adjacent lamp body units 20 overlap together, and the tool lamp is in a fully retracted state, with the smallest volume and overall shape, making it easy to carry, store and store.

[0085] It is worth mentioning that when the rotation angle is 0°, the two lamp body units 20 overlap and the tool lamp is in a fully retracted state. If the hook locking unit 40 is rotated and locked onto the connecting unit 30, the hook locking device 40 can prevent the lamp body unit 20 from being unfolded.

[0086] It is worth mentioning that, due to the rotation function of the connecting unit 30, when the lamp body unit 20 is flipped around the connecting unit 30 as the axis, the tool lamp can be in different unfolded states, so as to make the tool lamp have different usage states according to the needs of the lighting environment, making the tool lamp more flexible and practical to use.

[0087] like Figure 11AAs shown, the tool light is extended into a straight line and suspended from both sides of the car hood by the hook-lock unit 40. The hook-lock unit 40 is twisted and stretched to adjust the hook position, simultaneously changing the length of the tool light to fit the width of the car hood. Furthermore, the hook-lock unit 40 has a contraction reaction force during the stretching process, causing it to firmly fix the tool light to both sides of the hood. Figure 11B As shown, the tool light is rotated into a right angle and suspended from the top of the car hood via the hook-lock unit 40. Therefore, each unfolded state of the tool light creates a different illumination range. Thus, during use, the unfolded state of the tool light can be adjusted according to actual needs to achieve the desired lighting requirements, making the tool light more convenient and flexible to use.

[0088] Furthermore, the power supply unit 10 includes a battery, a control circuit, and a control switch. The battery and the control circuit are disposed inside the power supply unit 10, and the control switch is disposed on the outer wall of the power supply unit. The lamp body unit is electrically connected to the power supply, the control circuit, and the control switch, and the power supply provides electrical energy to the lamp body unit. Preferably, the battery is a rechargeable battery. The power supply unit also includes a charging port, which is electrically connected to the power supply.

[0089] Refer to the accompanying drawings of the specification of this invention. Figures 12 to 21 A tool lamp according to a preferred embodiment of the present invention will be disclosed and described below. The tool lamp includes two lamp bodies 10A, two mounting units 20A, and an extension 30A. Each mounting unit 20A is fixedly mounted to each end of the extension 30A, and each lamp body 10A is detachably mounted to each mounting unit 20A. The tool lamp has an assembled state and a disassembled state. In the assembled state, each lamp body 10A is mounted to each mounting unit 20A, thereby holding each lamp body 10A to opposite ends of the extension 30A. This allows the overall length of the tool lamp to be extended, enabling it to be suspended from a vehicle hood. Correspondingly, in the disassembled state, at least one lamp body 10A is detached from the mounting unit 20A and can be used independently. The tool lamp in different states provides different modes of use for the user to choose according to actual needs.

[0090] Preferably, in the disassembled state, the two lamp bodies 10A are respectively detached from the assembly unit 20A to allow the two lamp bodies 10A to be used individually.

[0091] Furthermore, each of the assembly units 20A is foldable, so that when the tool lamp is in the assembled state, the length of the tool lamp can be reduced by folding the assembly unit 20A, thereby facilitating the storage or carrying of the tool lamp.

[0092] Specifically, each assembly unit 20A includes a fixed arm 21A and a movable arm 22A rotatably mounted on the fixed arm 21A. The fixed arm 21A is fixedly mounted on the end of the extension body 30A, and the lamp body 10A is detachably mounted on the movable arm 22A. Thus, when the movable arm 22A rotates relative to the fixed arm 21A, the lamp body 10A rotates synchronously and with the same amplitude relative to the extension body 30A. Furthermore, the lamp body 10A is configured to overlap the extension body 30A. In this way, while reducing the length of the tool lamp by folding, the tool lamp in the folded state can be kept narrow.

[0093] More specifically, the lamp body 10A includes a power supply unit 11A, a light-emitting unit 12A, and a self-locking unit 13A. The power supply unit 11A and the self-locking unit 13A are respectively disposed at opposite ends of the light-emitting unit 12A, and the light-emitting unit 12A can be electrically connected to the power supply unit 11A. Thus, when the power supply unit 11A supplies power to the light-emitting unit 12A, the light-emitting unit 12A can generate light and radiate it in a preset direction. Correspondingly, the movable arm 22A of the assembly unit 20A has a mounting space 221A and at least one mounting hole 222A communicating with the mounting space 221A. The self-locking unit 13A of the lamp body 10A can be installed in the mounting space 221A of the movable arm 22A and self-locked in the mounting hole 222A. Thus, the lamp body 10A is installed in the movable arm 22A of the assembly unit 20A, so that the tool lamp is in the assembled state.

[0094] Continue to refer to the appendix Figures 16 to 19The self-locking part 13A of the lamp body 10A further includes a housing 131A, a self-locking seat 132A, a reset element 133A, and a self-locking element 134A. The housing 131A is mounted on the end of the light-emitting part 12A. The self-locking seat 132A is mounted on the housing 131A, and the self-locking seat 132A has a through hole 1321A. Two openings of the through hole 1321A are respectively formed on the side surface 1322A of the self-locking seat 132A. The reset element 133A is held in the through hole 1321A of the self-locking seat 132A. The self-locking element 134A has a… A sliding end 1341A and a corresponding locking end 1342A are provided. The self-locking element 134A is mounted on the self-locking seat 132A such that the sliding end 1341A is slidably mounted in the through hole 1321A of the self-locking seat 132A. The reset element 133A is held between the sliding ends 1341A of the two self-locking elements 134A, so that when the self-locking element 134A moves relative to the self-locking seat 132A, the two self-locking elements 134A can compress the reset element 133A, allowing the reset element 133A to accumulate elastic potential energy by deforming. The movable arm 22A of the assembly unit 20A has two mounting holes 222A. The opening of the mounting space 221A is formed on the end face of the movable arm 22A, and the two mounting holes 222A are formed in a corresponding manner on the side wall 223A of the movable arm 22A. The self-locking part 13A of the lamp body 10A is installed in the mounting space 221A of the movable arm 22A of the assembly unit 20A, and the locking ends 1342A of the two self-locking elements 134A of the self-locking part 13A are respectively held in the mounting holes 222A of the movable arm 22A by the reset element 133A, so that the lamp body 10A can be reliably installed in the assembly unit 20A.

[0095] During the installation of the lamp body 10A onto the assembly unit 20A, firstly, after the self-locking part 13A of the lamp body 10A is aligned with the mounting space 221A of the movable arm 22A of the assembly unit 20A, the lamp body 10A is pushed toward the movable arm 22A to allow the self-locking part 13A to enter the mounting space 221A of the movable arm 22A. Secondly, as the self-locking part 13A extends into the mounting space 221A of the movable arm 22A, the side wall 223A of the movable arm 22A simultaneously presses against the locking ends 1342A of the two self-locking elements 134A of the self-locking part 13A, allowing the sliding ends 1341A of the self-locking elements 134A to slide along the track formed by the through hole 1321A of the self-locking seat 132A into the interior of the self-locking seat 132A. At this time, the sliding ends 1341A of the two self-locking elements 134A compress the reset element 133A, allowing the reset element 133A to accumulate elastic potential energy in a deformable manner. Furthermore, when the self-locking part 13A extends into the mounting space 221A of the movable arm 22A to the position where the locking end 1342A of the self-locking element 134A of the self-locking part 13A corresponds to the mounting hole 222A of the movable arm 22A, the reset element 133A pushes the two self-locking elements 134A outward during the process of restoring the initial state, allowing the locking ends 1342A of the two self-locking elements 134A to automatically enter the mounting hole 222A of the movable arm 22A to install the lamp body 10A onto the movable arm 22A of the assembly unit 20A. The reset element 133A also allows the locking ends 1342A of the two self-locking elements 134A to be reliably held in the mounting hole 222A of the movable arm 22A, thereby ensuring the reliability of the installation relationship between the lamp body 10A and the movable arm 22A of the assembly unit 20A.

[0096] Preferably, at least a portion of the end face of the locking end 1342A of the self-locking element 134A of the self-locking part 13A is a bevel, so as to guide the self-locking part 13A to conveniently enter the installation space 221A of the movable arm 22A during the installation of the lamp body 10A into the installation space 221A of the movable arm 22A of the assembly unit 20A.

[0097] Accordingly, during the disassembly of the lamp body 10A from the assembly unit 20A, firstly, pressure is simultaneously applied to the locking end 1342A of the self-locking element 134A of the self-locking part 13A, allowing the sliding end 1341A of the self-locking element 134A to slide along the track formed by the through hole 1321A of the self-locking seat 132A into the interior of the self-locking seat 132A. At this time, the sliding ends 1341A of the two self-locking elements 134A compress the reset element 133A, allowing the reset element 133A to accumulate elastic potential energy by deforming. Secondly, the lamp body 10A is pulled away from the movable arm 22A of the assembly unit 20A, so that the lamp body 10A can disengage from the movable arm 22A of the assembly unit 20A, thus disassembling the lamp body 10A from the movable arm 22A of the assembly unit 20A. It is understood that after the lamp body 10A is detached from the movable arm 22A of the assembly unit 20A, the reset element 133A pushes the two self-locking elements 134A outward during the process of restoring the initial state, allowing the locking ends 1342A of the two self-locking elements 134A to be exposed on the side 1322A of the self-locking seat 132A.

[0098] It is worth mentioning that the specific type of the reset element 133A is not limited in the tool lamp of the present invention; for example, in the attached... Figures 12 to 21 In this specific example of the tool lamp shown, the reset element 133A is a compression spring.

[0099] Continue to refer to the appendix Figures 16 to 19The housing 131A has an assembly space 1311A, an assembly opening 1312A, and two through holes 1313A. The assembly opening 1312A connects to one end of the assembly space 1311A, and the two through holes 1313A connect to both sides of the assembly space 1311A in a corresponding manner. The self-locking seat 132A is installed in the assembly space 1311A of the housing 131A in a manner corresponding to the through hole 1321A of the self-locking seat 132A and the through hole 1313A of the housing 131A, and the size of the through hole 1321A of the self-locking seat 132A is larger than the size of the through hole 1313A of the housing 131A. The self-locking element 134A includes a sliding portion 1343A and a locking portion 1344A integrally extending outward from the sliding portion 1343A. The sliding portion 1343A forms the sliding end 1341A, and the locking portion 1344A forms the locking end 1342A. The size and shape of the sliding portion 1343A match the size and shape of the through hole 1321A of the self-locking seat 132A to allow the sliding portion 1343A to be slidably mounted on the self-locking seat 132A. Correspondingly, the size and shape of the locking portion 1344A match the size and shape of the through hole 1313A of the housing 131A to allow the locking portion 1344A to be movably held in the through hole 1313A of the housing 131A.

[0100] In other words, the self-locking seat 132A and the housing 131A can cooperate with each other to allow the self-locking element 134A to be slidably installed in the through hole 1321A of the self-locking seat 132A, so as to prevent the self-locking element 134A from disengaging from the self-locking seat 132A.

[0101] The housing 131A of the self-locking part 13A is installed on the light-emitting part 12A such that the end of the light-emitting part 12A extends into the assembly space 1311A through the assembly port 1312A of the housing 131A.

[0102] Continue to refer to the appendix Figures 16 to 19The self-locking element 134A includes a stabilizing post 1345A, wherein the stabilizing post 1345A extends integrally outward from the sliding portion 1343A, that is, the stabilizing post 1345A and the locking portion 1344A are integrally formed on opposite sides of the sliding portion 1343A, wherein the stabilizing post 1345A extends into the interior of the reset element 133A. Thus, during the sliding portion 1343A of the self-locking element 134A sliding along the track formed by the through hole 1321A of the self-locking seat 132A, the reset element 133A and the self-locking element 134A can be prevented from disengaging from each other, thereby ensuring the reliability of the self-locking part 13A of the lamp body 10A.

[0103] Furthermore, the through hole 1321A of the self-locking seat 132A has a middle section 13211A and outer sections 13212A located at opposite ends of the middle section 13211A. The size of the outer sections 13212A is larger than the size of the middle section 13211A. The size and shape of the middle section 13211A of the self-locking seat 132A match the size and shape of the stabilizing post 1345A of the self-locking element 134A. The outer portion 13212A of the self-locking seat 132A is sized and shaped to match the sliding portion 1343A of the self-locking element 134A, such that when the locking end 1342A of the self-locking element 134A in the self-locking part 13A is pressed, the sliding portion 1343A of the self-locking element 134A is restricted to sliding in the middle portion 13211A of the through hole 1321A of the self-locking seat 132A.

[0104] Preferably, the outer portion 13212A of the self-locking seat 132A is generally square in shape, and correspondingly, the sliding portion 1343A of the self-locking element 134A is generally square in shape. In this way, as the sliding portion 1343A of the self-locking element 134A slides along the outer portion 13212A of the self-locking seat 132A, the self-locking element 134A can be prevented from rotating relative to the self-locking seat 132A.

[0105] Preferably, the extension 30A is capable of generating light, such that the extension 30A not only extends the physical length of the tool lamp to allow the tool lamp to be suspended on the hood of the vehicle, but also extends the length of the light-emitting portion of the tool lamp, so that when the tool lamp is suspended on the hood of the vehicle, the tool lamp can generate light along its entire length to provide sufficient illumination for the engine compartment of the vehicle.

[0106] Specifically, after the self-locking part 13A of the lamp body 10A is installed in the mounting space 221A of the movable arm 22A of the assembly unit 20A, the electrical energy of the lamp body 10A can be supplied to the extension body 30A through the assembly unit 20A, so that the light-emitting part of the extension body 30A can generate light, thus making it convenient for the user to select the usage state of the tool lamp between the assembled state and the disassembled state.

[0107] More specifically, the tool lamp further includes an electrical connection unit 40A having a series of conductive posts 41A and a series of conductive holes 42A. The series of conductive posts 41A are disposed on the movable arm 22A and protrude from the mounting space 221A of the movable arm 22A. The series of conductive holes 42A are formed at the end of the housing 131A of the self-locking part 13A. When the self-locking part 13A of the lamp body 10A is installed in the mounting space 221A of the movable arm 22A, the series of conductive posts 41A of the electrical connection unit 40A are automatically inserted into and held in the series of conductive holes 42A, so that the electrical energy of the lamp body 10A can be supplied to the extension body 30A through the assembly unit 20A.

[0108] Continue to refer to the appendix Figures 12 to 21 The lamp body 10A further includes a suspension portion 14A, wherein the suspension portion 14A is disposed outside the power supply portion 11A for suspending the tool lamp on the hood of the vehicle. Furthermore, the direction of the suspension portion 14A can be rotated, so that when the tool lamp is in a folded state, the suspension portion 14A can hook onto the mounting unit 20A, allowing the tool lamp to be stably held in the folded state. Figure 13 As shown.

[0109] Figure 20 The illustration shows a usage state of the tool lamp of the present invention, in which two lamp bodies 10A are respectively mounted on two assembly units 20A, allowing the two lamp bodies 10A, the two assembly units 20A and the extension body 30A to form an extended structure. At this time, the tool lamp can be suspended on the hood of the vehicle by the suspension part 14A of the two lamp bodies 10A, so that the light generated by the two lamp bodies 10A and the extension body 30A can provide sufficient illumination to the engine compartment of the vehicle.

[0110] Appendix Figure 21Another mode of use of the tool lamp of the present invention is shown, wherein the lamp body 10A is allowed to be detached from the assembly unit 20A, in which case the user can use the lamp body 10A by holding it. Preferably, the power supply part 11A of the lamp body 10A forms a handle of the lamp body 10A, that is, the user can use the lamp body 10A independently by holding the power supply part 11A of the lamp body 10A.

[0111] Those skilled in the art will understand that the embodiments of the present invention shown in the accompanying drawings and described above are merely examples of the present invention and not limitations.

[0112] Therefore, it can be seen that the objective of the present invention can be fully and effectively achieved.
