Description

HANDLE MECHANISM, LIGHTING FIXTURE, AND PORTABLE TOOLFIELD OF THE INVENTION

[0001] The present invention relates to the technical field of handles, particularly to a handle mechanism, a lighting fixture, and a portable tool.BACKGROUND OF THE INVENTION

[0002] In order to make some lighting fixtures, such as outdoor lamps and large lamps, more portable and easier to use, a clamping structure is installed on the lamp body of a lighting fixture currently available on the market, which allows the lighting fixture to provide a clamping or hanging function, so that it can be clamped or hung on an object for use, and, meanwhile, the lighting fixture can be conveniently lifted by the clamping structure.

[0003] However, an existing lighting fixture adopting a clamping structure has the following problems:

[0004] 1 . After the clamping structure is pulled out and released, it automatically retracts and tightly clamps the lamp body, likely to injure the hand. Moreover, due to the need to ensure that the clamping structure can automatically be restored to its original position, a sufficient restoring force needs to be provided, so it requires considerable physical exertion to pull out the clamping structure;

[0005] 2. A button is provided on the lamp body to control the movement of the clamping structure. When the button is pressed, the clamping structure automatically pops out of the lamp body. When the clamping structure needs to be retracted, it is necessary to push the clamping structure by hand until it is integrated with the lamp body, or push it to a suitable position so that a certain space is formed between the clamping structure and the lamp body, and then hang the clamping structure on an object to suspend the lighting fixture, which, however, can be hung but not clamped, and thus is unstable.SUMMARY OF THE INVENTION

[0006] An embodiment of the present invention provides a handle mechanism aimed at solving the technical problem of a lighting fixture with a clamping structure in the prior art being inconvenient to use.

[0028] Further, the transmission element is provided with a locking hole on one end near the locking block, and the locking block is provided with an assembly portion corresponding to the locking hole, the assembly portion being fitted in the locking hole;

[0029] Alternatively, the transmission element is provided with an assembly portion on one end near the locking block, and the locking block is provided with a locking hole corresponding to the assembly portion, the assembly portion being fitted in the locking hole.

[0030] Further, the inner bottom surface of the tool housing is provided with a first sliding rail distributed along the sliding direction of the pull rod, and the bottom surface of the pull rod is provided with a first sliding groove corresponding to the first sliding rail, wherein the first sliding rail and the first sliding groove cooperate with each other;

[0039] Further, a buffer element distributed along the width direction of the clamping portion is further arranged on one side thereof facing the tool housing.

[0040] Further, the number of pull rods is two, and the two pull rods are respectively located at both ends of the gripping element;

[0041] The locking assemblies are divided into two groups, the two groups of locking assemblies being respectively arranged on the two pull rods and the corresponding tool housing.

[0042] The present invention further provides a lighting fixture comprising:

[0043] A tool housing; and

[0044] A handle mechanism as described above, slidably connected to the tool housing, the locking structure being provided on the tool housing.

[0045] The present invention further provides a portable tool comprising:

[0048] In the present invention, the handle body is slidably connected to the tool housing, and can be inwardly retracted into the tool housing or pulled out from the tool housing. After it is pulled out, the tool can be lifted, hung, and clamped for easy use. When it is retracted, the tool can be kept neat and compact for convenient placement and receipt.

[0049] Due to the fact that the locking block can be driven by the transmission element to rotate from a first position to a second position relative to the handle body, when the locking block is in the first position, it locks with the locking structure, and when rotating from the first position to the second position, it unlocks from the locking structure, which allows a user to control the movement of the locking block by manipulating the transmission element, thereby controlling the relative position relationship between the handle body and the tool housing. For example, the locking block can lock with the locking structure, thus keeping the handle body in a position where it is pulled out relative to the tool housing for use, or it can be retracted into the tool housing, without beingpulled out, to remain in a relatively compact state, or the locking block can unlock from the locking structure, allowing the handle body to be pushed back into the tool housing for accommodation or be pulled continuously outwards, so the operations are easy and convenient.

[0050] Further, since the locking block continuously provides a turning force for rotating from the second position to the first position, which means that even if driven by the transmission element to the second position, the locking block still continuously rotates towards the first position, when the user does not operate the unlocking assembly, for example, after the user releases the handle body, the locking block, under the continuous turning force, returns to the first position and automatically locks with the locking structure, so that the handle body will not retract immediately after being released and cause accidental injury, which improves the safety of use.BRIEF DESCRIPTION OF THE FIGURES

[0069] Referring to Figure 1 to Figure 6, the handle mechanism 10 according to an embodiment of the present invention is configured to be extendable or retractable in cooperation with the tool housing 20, the handle mechanism 10 comprising:

[0070] A handle body 11 , the handle body 11 being slidably connected to the tool housing 20, which can be retracted into the tool housing 20 or pulled out from the tool housing 20; and

[0071] A locking assembly 12, the locking assembly 12 comprising a locking structure 121 provided on the tool housing 20, a locking block 122 provided on the handle body 11 , and a transmission element 123 provided on the handle body 11 and transmissively connected to the locking block 122, wherein the locking block 122 may be driven by the transmission element 123 to rotate from a first position relative to the handle body 11 to a second position, the locking block 122 having a continuous turning force for rotating from the second position to the first position;

[0072] When the locking block 122 is in the first position, it locks with the locking structure 121 , and when the locking block 122 rotates from the first position to the second position, it unlocks from the locking structure 121.

[0073] In the present invention, the handle body 11 is slidably connected to the tool housing 20, and can be retracted and accommodated inside the tool housing 20 or pulled out from the tool housing 20. After it is pulled out, the tool can be lifted, hung, and clamped for easy use. When it is retracted, the tool can be kept neat and compact for convenient placement and receipt. Due to the fact that the locking block 122 can be driven by the transmission element 123 to rotate from a first position relative to the handle body 11 to a second position, it is locked with the locking structure 121 when in the first position, and unlocked from the locking structure 121 when rotating from the first position to the second position. This allows a user to control the movement of the locking block 122 by manipulating the transmission element 123, thereby controlling the relative position relationship between the handle body 11 and the tool housing 20.

[0074] For example, the locking block 122 can lock with the locking structure 121 , thus keeping the handle body 11 in a position where it is pulled out relative to the tool housing 20 for use, or it can be retracted and accommodated in the tool housing 20, without being pulled out, to remain in a relatively compact state, or the locking block 122 can unlock from the locking structure 121 , allowing the handle body 11 to be retracted and accommodated in the tool housing 20 or pulled continuously outwards, so the operations are easy and convenient.

[0075] Further, since the locking block 122 continuously provides a turning force for rotating from the second position to the first position, which means that even if driven by the transmission element 123 to the second position, the locking block 122 still continuously rotates towards the first position, when the user does not operate the unlocking assembly, for example, after the user releases the handle body 11 , the locking block 122, under the continuous turning force, returns to the first position and automatically locks with the locking structure 121 , so that the handle body 11 will not retract immediately after being released and cause accidental injury, which improves the safety of use.

[0076] The handle mechanism 10 of the present embodiment is applicable to lighting tools, for example, the lighting fixture 100, storage tools such as suitcases, and power supply tools such as inverters and outdoor power supplies. Such a tool may comprise a tool housing 20 for installing related structures, the tool housing 20 being, for example, the lamp body of the lighting fixture 100, the body of a suitcase, or the housing of an inverter. The handle mechanism 10 is slidably connected to the tool housing 20, the tool housing 20 having an internal space that allows the handle body 11 to be pulled out or be retracted and accommodated in the internal space.

[0077] In an embodiment of the present invention, the sliding connection between the handle body 11 and the tool housing 20 is achieved through the locking assembly 12 provided on the handle body 11 and the tool housing 20, and the locking assembly can also be used to control the relative positional relationship between the handle body 11 and the tool housing 20. The handle body 11 can be pulled out of the tool housing 20 or be accommodated in the tool housing 20, so it is a part that a user can pull and push, or a part that can be used for clamping and hanging.

[0078] The locking structure 121 and locking block 122 of the locking assembly 12 are respectively provided on the tool housing 20 and the handle body 11 , and are both provided with structures cooperating with each other, such as rough friction surfaces and interlocking irregularities / tooth-shaped structures. In other words, both the locking structure 121 and the locking block 122 are provided with rough friction surfaces, or the locking structure 121 may be provided with grooves / protrusions / locking teeth, etc., while the locking block 122 may correspondingly be provided with protrusions / grooves / locking teeth, etc., to allow cooperative locking between the two by friction or interlocking, so that the handle body 11 is immovable by pulling or pushing; when the locking structure121 and the locking block 122 are separated or disengage from each other, the locking between them is released, so that the handle body 11 becomes movable by pulling or pushing.

[0079] One end of the transmission element 123 of the locking assembly 12 is transmissively connected to the locking block 122, and the other end thereof is operable by a user. For example, a user can control the movement of the locking block 122 by pulling, pushing, or pressing the transmission element 123. For example, the transmission element 123 can be pulled to drive the locking block 122 to rotate from a first position to a second position, thereby releasing the lock, or to drive the locking block122 to rotate from the second position to the first position to relock, or to keep the locking block 122 in the first position to maintain the locking.

[0080] The locking block 122 may be installed by arranging a rotating shaft 1124 on the handle body 11 , in order to allow rotation with respect to the handle body 11. In this embodiment, the first and second positions mentioned above can be understood as two extreme positions in which the locking block 122 can rotate on the handle body 11 .

[0081] As shown in Figure 5, the first position is the position in which the locking block 122 in a natural state, for example, the position taken by the locking block 122 when the handle body 11 is fully accommodated in the tool housing 20, or the position taken by the locking block 122 when the handle body 11 , in the open state, is not further movableby pulling or pushing. The first position can also be understood as the position where the area of contact between the locking block 122 and the locking structure 121 is the largest, or the position where the connection therebetween is the closest, so that the locking block 122 and the locking structure 121 can stably cooperate for locking;

[0082] As shown in Figure 6, the second position is the position where the locking block 122 separates / disengages from the locking structure 121 after rotation, for example, the position taken by the locking block 122 when the handle body 11 is pulled out of the tool housing 20 or pushed into the tool housing 20. The second position can also be understood as the position where the area of contact between the locking block 122 and the locking structure 121 is the smallest or they are completely separated from each other, so that the locking between the locking block 122 and the locking structure 121 is released.

[0083] Further, a limit structure can be arranged on the locking block 122 or the handle body 11 to restrict the rotation of the locking block 122, so that it can rotate only between the first and second positions, thereby controlling the amplitude of rotation of the locking block 122. This allows the locking block 122 to move more quickly, that is, locking with or unlocking from the locking structure 121 more quickly.

[0084] Rotation of the locking block 122 from the first position to the second position can be either clockwise or counterclockwise. It can be understood that since an outwards pulling action is a reverse action, in this embodiment, rotation of the locking block 122 from the first position to the second position is counterclockwise rotation, and rotation thereof from the second position to the first position is clockwise rotation. In other words, the second position is located further outside than the first position, or it can be understood that the second position is closer to the outer side of the tool housing 20, while the first position is located further inside.

[0085] In this embodiment, the locking block 122 rotates from the first position to the second position, so that the locking block 122 is gradually unlocked from the locking structure 121 . This can be understood as the area of contact or connection between the locking block 122 and the locking structure 121 becoming increasingly smaller and looser, for example, the engaging of a tooth structure becoming increasingly slighter and less. When the locking block 122 has completely rotated to the second position, the locking block 122 and the locking structure 121 are completely separated, thereby releasing the lock.

[0086] Correspondingly, the locking block 122 rotates from the second position to the first position, causing the locking block 122 to cooperate with the locking structure 121for locking. This can be understood as the area of contact or connection between the locking block 122 and the locking structure 121 becoming increasingly larger and closer, for example, the engaging of a tooth structure becoming increasingly greater and more numerous. When the locking block 122 has fully rotated to the first position, the locking block 122 and the locking structure 121 are fully in contact with each other, thereby achieving effective locking.

[0087] In this embodiment, the locking block 122 having a continuous turning force for rotating from the second position to the first position can be understood as follows: it continuously produces a force for rotation towards the first position when the locking block 122 is in the second position or in any position between the first and second positions; when the external force acting on the locking block 122 has disappeared or the rotation is not hindered, for example, when the transmission element 123 does not transmit the locking block 122, the locking block 122 will rotate back to the first position under the action of this turning force.

[0088] In one embodiment, a deformable element, for example, a spring, can be installed in the locking block 122, and rotation of the locking block 122 will cause the element to deform, causing the locking block 122 to have a turning force.

[0089] In another embodiment, the locking block 122 may also be manufactured with a deformable material, so that the locking block 122 itself undergoes deformation during rotation, thereby generating a turning force.

[0090] For example, in a feasible embodiment, operations between the handle mechanism 10 and the tool housing 20 can be as follows:

[0091] When the handle body 11 is accommodated in the tool housing 20, the locking block 122 is in the first position and locked with the locking structure 121 , and the handle body 11 cannot be pulled out. In this case, a user can pull the transmission element 123 outwards, and the transmission element 123 drives the locking block 122 to rotate counterclockwise from the first position to the second position to unlock from the locking structure 121 , so that the user can then pull the handle body 11 outwards;

[0092] After pulling out the handle body 11 to the desired position, the user stops pulling the handle body 11 , in which case the transmission element 123 can be pushed backwards to push the locking block 122 from the second position back to the first position, or the transmission element 123 can automatically reset, causing the locking block 122 to rotate back to the first position, or the locking block 122 can be reset from the second position to the first position under the continuous turning force, or the lockingblock 122, under the combined action applied by the above methods, can be reset to the first position to relock with the locking structure 121 ;

[0093] In the state where the handle body 11 is pulled out, when it is necessary to reset and retract the handle body 11 into the tool housing 20, the transmission element 123 can be operated to rotate the locking block 122 from the first position to the second position to unlock from the locking structure 121 , and then the handle body 11 can be pushed back and accommodated in the tool housing 20; alternatively, since the locking block 122 has a continuous turning force for rotating from the second position to the first position, and the locking block 122 is provided on the handle body 11 , it can provide a force for inwardly retracting the handle body 11 , so that the handle body 11 can be easily pushed back into the tool housing 20, without the need for operating again the transmission element 123 to rotate the locking block 122, which provides greater convenience of use.

[0094] Referring to Figure 7 and Figure 8, as well as Figure 11 and Figure 12, further, the locking block 122 is internally provided with a torsion spring 1221 , wherein the starting end of the torsion spring 1221 is fixed to the handle body 11 , and the rear end thereof abuts the inner wall of the locking block 122. The torsion spring 1221 continuously provides a turning force for the locking block 122 to rotate from the second position to the first position. When the locking block 122 continuously rotates from the first position to the second position, the torsion spring 1221 is continuously compressed.

[0095] Specifically, the torsion spring 1221 is placed in a compressed state inside the locking block 122, and the starting end of the torsion spring 1221 is fixed to the handle body 11 , while the rear end thereof abuts the inner wall of the locking block 122, which continuously provides a turning force for the locking block 122 to rotate from the second position to the first position. At the same time, the torsion spring 1221 also exerts a certain force on the handle body 11.

[0096] When the handle body 11 moves, the locking block 122 drives the torsion spring 1221 to compress clockwise or counterclockwise, causing the torsion spring 1221 to apply turning forces of varying magnitudes on the handle body 11. In this embodiment, when the locking block 122 continuously rotates from the first position to the second position, that is, when the locking block 122 rotates counterclockwise, the torsion spring 1221 is continuously compressed, which means that the torsion spring 1221 is driven counterclockwise to twist and be compressed, generating a greater torsional force. Therefore, the further outwards the handle body 11 is pulled, the greater thetorsional / turning force the torsion spring 1221 generates, thereby providing a greater clamping force on the handle body 11 and improving the stability during clamping.

[0097] In addition, the locking block 122 is a hollow structure for a reduction in its own weight, so that it is more easily driven to rotate by the transmission element 123 and is also easier to reset and rotate under the turning force provided by the torsion spring 1221 , improving control sensitivity.

[0098] Referring to Figure 7, Figure 8, and Figure 12, further, the transmission element 123 can perform reciprocating motion along the length direction of the handle body 11 , driving the locking block 122 to rotate back and forth between the first position and the second position.

[0099] In other words, in this embodiment, the linear motion of the transmission element 123 is convertible into the rotational motion of the locking block 122. The transmission mode is not only simple, clear, and easy to implement, but also easy to control. For example, the user can push or pull the transmission element 123 to perform reciprocating motion, so that the locking block 122 can rotate back and forth between the first position and the second position, effectively realising the control of locking and unlocking between the locking block 122 and the locking structure 121.

[0100] For example, the action between the transmission element 123 and the locking block 122 can be as follows:

[0101] When the transmission element 123 moves along the length direction of the handle body 11 towards the outside of the tool housing 20, if the user pulls the transmission element 123 to move outwards, the locking block 122 rotates counterclockwise to move from the first position to the second position, in which case the locking block 122 is unlocked from the locking structure 121 ;

[0102] When the transmission element 123 moves along the length direction of the handle body 11 towards the interior of the tool housing 20, if the user pushes the transmission element 123 inwards, the locking block 122 rotates clockwise to move from the second position to the first position, in which case the locking block 122 is locked with the locking structure 121.

[0103] The above content about the action and control of the transmission element 123 and the locking block 122 is only exemplary and should not be construed as limiting the present invention, as long as arrangement is done according to specific needs.

[0104] Referring to Figure 5 to Figure 8, further, the handle body 11 comprises:

[0105] A gripping element 111 , the gripping element 111 being able to be fitted in or spaced apart from the tool housing 20; and

[0106] A pull rod 112 connected to the gripping element 111 and extending towards the interior of the tool housing 20, wherein the locking block 122 and the transmission element 123 are both arranged on the pull rod 112, and the pull rod 112 can be inwardly retracted and accommodated in the tool housing 20 or pulled out from the tool housing 20, allowing the gripping element 111 to be fitted in or spaced apart from the tool housing 20.

[0107] In this embodiment, the gripping element 111 is a part for a user to push / hold / lift, clamp objects, or hang on objects. When the gripping element 111 is pulled out, it is spaced apart from the tool housing 20, and the handle body 11 is pulled out from the tool housing 20. When the gripping element 111 is fitted into the tool housing 20, the handle body 11 is retracted into the tool housing 20.

[0108] The gripping element 111 has a certain thickness and can be rod-shaped or block / plate-shaped. In order to facilitate clamping or improve stability during clamping / suspension, in one embodiment, the gripping element 111 may be plateshaped, which increases the area of contact with an object, thereby enhancing stability during clamping and suspension.

[0109] Further, an opening can be made along the thickness direction of the gripping element 111 , dividing the gripping element 111 into two parts, one of which is larger and the other smaller in volume. The user's palm can pass through the opening to grip the smaller part, making it convenient to hold and use, while the overall area of contact of the gripping element 111 is still large enough to ensure stability during clamping and hanging.

[0110] In this embodiment, the pull rod 112 can be in the shape of a long strip, which is the part establishing a slidable connection between the gripping element 111 and the tool housing 20. In other words, the gripping element 111 is spaced or fitted with the tool housing 20 through the pull rod 112. The locking structure 121 is specifically located above the pull rod 112. Therefore, the locking block 122 is arranged on the pull rod 112 to cooperate with the locking structure 121 arranged on the tool housing 20, while the transmission element 123 is arranged on the pull rod 112 to facilitate the operation of the locking block 122.

[0111] Again referring to Figure 5 to Figure 8, further, two pull rods 112 are provided, the two pull rods 112 being respectively located at both ends of the gripping element 111 ; the locking assemblies 12 are divided into two groups, and the two groups of locking assemblies 12 are respectively arranged on two pull rods 112 and the corresponding tool housing 20.

[0112] It is understandable that two pull rods 112 can enhance the stability of the handle body 11 when pulled out or pushed. The gripping element 111 is in the shape of a rectangular plate, and the two pull rods 112 are respectively arranged at the two ends of the gripping element 111 in the length direction, resulting in more uniform force distribution, so the tool can be lifted, pulled, clamped, or suspended more stably.

[0113] The locking assemblies 12 are divided into two groups, which means that there are two groups of transmission element 123, locking block 122, and locking structure 121. One group of transmission element 123, locking block 122, the locking structure 121 is arranged on one of the pull rods 112 and the tool housing 20 corresponding to the pull rod 112. The other group of transmission element 123, locking block 122, and locking structure 121 is arranged on the other pull rod 112 and the tool housing 20 corresponding to the pull rod 112. The two groups of transmission element 123, locking block 122, and locking structure 121 are arranged on both sides of the tool housing 20 to enhance the stability of the structure.

[0114] Referring to Figure 7 and Figure 8, further, the locking block 122 is rotatably provided at one end of the pull rod 112 away from the gripping element 111 , and the transmission element 123 is slidably provided along the length direction of the pull rod 112, with its end away from the gripping element 111 being transmissively connected to the locking block 122.

[0115] To ensure that the pull rod 112 can be pulled long enough to meet different user needs, in this embodiment, the locking block 122 is rotatably arranged on the end of the pull rod 112 away from the gripping element 111 , specifically on a side of the pull rod 112, for example, on the inner side of the pull rod 112. The end of the transmission element 123 away from the gripping element 111 is transmissively connected to the locking block 122, and its end close to the gripping element 111 is operable by the user. When the user operates the transmission element 123 to slide along the length direction of the pull rod 112, the locking block 122 is driven to rotate, controlling the locking or unlocking between the handle body 11 and the tool housing 20.

[0116] Referring to Figure 8 and Figure 12, further, the pull rod 112 is provided with a movable groove 1121 along its length direction, and the transmission element 123 is slidably arranged in the movable groove 1121.

[0117] Specifically, the movable groove 1121 is arranged on the inner wall of the pull rod 112, which can be formed by a certain depth of inward depression of the inner wall of the pull rod 112. The movable groove 1121 is arranged along the length direction of the pull rod 112, so that the transmission element 123 can slide along the length directionof the pull rod 112. This not only improves the utilisation of the space of the pull rod 112, but also allows the transmission element 123 to adhere to the inner wall of the movable groove 1121 , which makes the arrangement more stable and is conducive to improving structural stability.

[0118] Referring to Figure 7 and Figure 8, further, the gripping element 111 is provided with a trigger element 113 that can be pressed relative to the gripping element 111 , and the transmission element 123 is connected to the trigger element 113 at one end near the gripping element 111.

[0119] For the convenience of user operation, in this embodiment, a trigger element 113 is provided on the gripping element 111 , which can be in the form of a button. The trigger element 113 can be arranged along the length direction of the gripping element 111 , making it easier for users to, when holding the gripping element 111 , directly press and operate it. By pressing the trigger element 113, a user can control the movement of the transmission element 123, and then control the action of the locking block 122, thereby easily and conveniently controlling the locking and unlocking of the handle body 11 and the tool housing 20.

[0120] An example is given as follows:

[0121] When the trigger element 113 is pressed towards the gripping element 111 , the transmission element 123 is driven to slide in the direction closer to the gripping element 111 , and the locking block 122 is driven by the transmission element 123 to rotate from the first position to the second position. In other words, when the trigger element 113 is pressed towards the gripping element 111 , the transmission element 123 is driven to slide outwards, causing the locking block 122 to rotate counterclockwise, from the first position to the second position, thus unlocking with the locking structure 121 , so that the handle body 11 can be pulled out for use;

[0122] When the trigger element 113 is reset from the pressed state, the transmission element 123 is driven to slide away from the gripping element 111 , and the locking block 122 is driven by the transmission element 123 to rotate from the second position to the first position. In other words, when the trigger element 113 is reset from the inside to the outside of the gripping element 111 , the transmission element 123 is driven to slide inwards, causing the locking block 122 to rotate clockwise, from the second position to the first position, thus locking with the locking structure 121 , so that the handle body 11 cannot be pulled out.

[0123] Further, in order to allow the resetting of the trigger element 113 and provide control feedback to the user, a reset structure may be provided between the triggerelement 113 and the inner wall of the gripping element 111 , such as a mounting rod and a reset spring fitted with a mounting rod. The two ends of the reset spring respectively abut the inner walls of the trigger element 113 and the gripping element 111.

[0124] In a normal state, the trigger element 113 is pushed outwards by the spring and protrudes from the gripping element 111 , in which case the locking block 122 is in the first position. When the user presses the trigger element 113, the user can receive elastic feedback from the spring and know that the trigger element 113 is being pressed, in which case the trigger element 113 drives the transmission element 123 to move outwards, thereby driving the locking block 122 to turn from the first position to the second position for unlocking, so that the handle body 11 can be pulled or pushed.

[0125] When the user releases the trigger element 113, in one scenario, the spring acts on the trigger element 113 to reset it, the trigger element 113 drives the transmission element 123 to move inwards, and the transmission element 123 in turn drives the locking block 122 to turn from the second position to the first position for locking, thereby keeping the handle body 11 in its current position.

[0126] In another scenario, due to the continuous turning force of the locking block 122, when the user releases the trigger element 113, the locking block 122 automatically rotates from the second position to the first position to lock with the locking structure 121. Thus, the transmission element 123 is driven inwards by the locking block 122, and the trigger element 113 can quickly reset under the joint action of the spring and the locking block 122.

[0127] In this embodiment, the trigger element 113 is reset on the gripping element 111 under the joint action of the locking block 122 and the spring.

[0128] Referring to Figure 5, Figure 6, Figure 10, and Figure 11 , further, the locking block 122 comprises a protrusion 1222 corresponding to the locking structure 121 , and the protrusion 1222 can rotate with the locking block 122 between the first position and the second position. The locking structure 121 comprises a locking portion 1211 located inside the tool housing 20. When the locking block 122 is in the first position, the protrusion 1222 abuts and locks with the locking portion 1211. When the locking block 122 rotates from the first position to the second position, the protrusion 1222 disengages from the locking portion 1211 for unlocking.

[0129] In this embodiment, the protrusion 1222 is a part of the locking block 122 itself, so it can rotate together with the locking block 122. The locking block 122 has the shape of a block, so the protrusion 1222 can be formed by protruding outwards from a certain part around the locking block 122. For example, the protrusion 1222 can be formed byprotruding upwards from the top of the locking block 122, and the protrusion 1222 can have the shape of a sharp tooth, so that the locking block 122 is not easily pushed apart when it is locked with the locking structure 121 , ensuring stability during locking.

[0130] If the protrusion 1222 is tooth-shaped, similarly, the locking portion 1211 is also tooth-shaped. The protrusion 1222 can be pressed or clamped between the two teeth of the locking portion 1211 to achieve locking with the locking portion 1211 , that is, to allow locking between the locking block 122 and the locking structure 121.

[0131] When the locking block 122 gradually rotates from the first position to the second position, the protrusion 1222 and the locking portion 1211 gradually disengage from each other until they are completely separated, for example, the teeth of the two parts gradually disengage from each other until complete separation, so that the locking block 122 is unlocked from the locking structure 121.

[0132] When the locking block 122 gradually rotates from the second position to the first position, the protrusion 1222 gradually comes into contact with the locking portion 1211 until they are fully locked, for example, the teeth of the two parts gradually coming into contact with each other until they are fully engaged, so that the locking block 122 is locked with the locking structure 121.

[0133] In another embodiment, the locking block 122 may have a rough friction surface, and the locking structure 121 may also have an opposite rough friction surface. The locking of the locking block 122 with the locking structure 121 is achievable by full contact or large-area contact between the two rough friction surfaces, so that the handle body 11 cannot be pulled or pushed. The separation and unlocking between the locking block 122 and the locking structure 121 is achievable by the disengagement between the two rough friction surfaces for separation, or simply small-area contact, so that the handle body 11 can be easily pulled or pushed.

[0134] The preceding description of the cooperation between the locking block 122 and the locking structure 121 for locking and unlocking is only exemplary and should not be construed as a limitation of this embodiment. In other embodiments, the cooperation between the locking block 122 and the locking structure 121 can also be in another manner.

[0135] Referring to Figure 7, Figure 8, and Figure 10, further, the locking block 122 is a cam, and the protrusion 1222 is a protruding tooth arranged at the top of the locking block 122. The locking structure 121 is a rack arranged along the sliding direction of the locking block 122 on the tool housing 20. The locking portion 1211 is a gnawing tooth onthe locking structure 121 , and the shape of the protrusion 1222 is adapted to the shape of the locking portion 1211.

[0136] In this embodiment, the cam structure is combined with a torsion spring 1221 provided therein and a protruding tooth formed thereon to form a locking block 122. The protruding tooth and the gnawing tooth have the same size to ensure they adapt to each other completely for stable locking. In addition, the locking block 122 further comprises a rotating shaft 1124. One end of the rotating shaft 1124 is arranged on the tension rod 112, and the other end thereof is threaded with the locking block 122 and the torsion spring 1221. In other words, the torsion spring 1221 is fixed on the rotating shaft 1124 to avoid displacement caused by pulling, which may result in a failure.

[0137] By the above design, the further outwards the handle body 11 is pulled, the greater the rotation amplitude of the locking block 122 is. For example, the locking block 122 will be kept in the second position, and, at the same time, the torsion spring 1221 inside the locking block 122 will be compressed more tightly, thereby generating a greater turning force, so the handle mechanism 10 can be clamped to an object more tightly, improving the stability of tool clamping and suspension.

[0138] The sliding direction of the locking block 122 is the direction of movement of the handle body 11 , or can be understood as the sliding direction of the transmission element 123. The rack is arranged inside the tool housing 20 and aligned with the movement of the locking block 122 along the sliding direction of the locking block 122. This effectively achieves stable locking and effective unlocking between the locking block 122 and the locking structure 121 by means of the engaging between the gnawing tooth and the rack. In addition, by separating the gnawing tooth and the rack, the locking block 122 is caused to disengage from the locking structure 121 for unlocking; when the gnawing tooth and the rack engage, the locking block 122 is locked with the locking structure 121. In addition, when the user pulls or pushes the handle body 11 , the user can receive feedback on the contact between the protruding tooth and the rack, which improves the user experience.

[0139] Further, in this embodiment, the locking structure 121 comprises two parallel racks, and the locking block 122 cooperates with the two racks for locking or unlocking. The area of contact between the two racks and the locking block 122 is increased, providing a greater locking force and improving the stability of the locking block 122 when it is locked with the locking structure 121 in the first position.

[0140] In other embodiments, the locking structure 121 may further comprise more or fewer racks, for example, three or more racks, to further enhance the stability of thelocking block 122 when it is locked with the locking structure 121. It may also only comprise one rack to simplify the structure of the locking assembly 12 and the handle mechanism 10, thus reducing the overall structural complexity.

[0141] Referring to Figure 5, Figure 6, and Figure 11 , further, the protrusion 1222 comprises a first tooth 12221 and a second tooth 12222 adjacent to each other. In the direction facing the outside of the tool housing 20, the first tooth 12221 is located before the second tooth 12222, and the first tooth 12221 is larger than the second tooth 12222.

[0142] In this embodiment, the first tooth 12221 is a tooth with a sharp end, the second tooth 12222 is a tooth without a sharp end, and there is a gap between the first tooth 12221 and the second tooth 12222, the gap having a shape the same as that of the locking portion 1211 of the locking structure 121. When the locking block 122 is locked with the locking structure 121 , the first tooth 12221 fully engages the locking portion 1211 (namely, the gnawing tooth) of the locking structure 121 , and the second tooth 12222 partially engages with the locking portion 1211 of the locking structure 121 , making it easy to separate from the locking structure 121. The partial locking portion 1211 of the locking structure 121 engages the above-mentioned gap, allowing the mating of the fixed part and the locking portion 1211.

[0143] The first tooth 12221 is configured to allow stable engagement between the locking block 122 and the locking structure 121 , while the second tooth 12222 is configured to further enhance the locking stability between the locking block 122 and the locking structure 121. For example, when the locking block 122 is locked with the locking structure 121 , the handle body 11 is pushed inwards. The locking structure 121 , on the basis of engaging the first tooth 12221 to hinder the movement of the locking block 122, also engages the second tooth 12222 to further hinder the locking block 122.

[0144] Referring to Figure 7, Figure 8, Figure 11 , and 12, further, a locking hole 1231 is arranged on one end of the transmission element 123 near the locking block 122, and an assembly portion 1223 corresponding to the locking hole 1231 is provided on the locking block 122, the assembly portion 1223 being fitted in the locking hole 1231 ;

[0145] Alternatively, the transmission element 123 is provided with an assembly portion on one end near the locking block 122, and the locking block 122 is provided with a locking hole corresponding to the assembly portion 1223, with the assembly portion fitted in the locking hole.

[0146] In this embodiment, the transmission element 123 is transmissively connected to the locking block 122. Specifically, a locking hole 1231 can be provided at the end of the transmission element 123, and an assembly portion 1223 corresponding to the lockinghole 1231 can be provided on the locking block 122, or at the end of the transmission element 123, wherein a locking hole corresponding to the assembly portion is arranged on the locking block 122.

[0147] The assembly portion 1223 is a block-shaped protrusion on the surface of the transmission element 123 or the locking block. The shape of the locking hole 1231 is adapted to the cross-sectional shape of the assembly portion 1223, and the size of the locking hole 1231 is the same as or similar to that of the assembly portion 1223. For example, the assembly portion 1223 is slightly smaller than the locking hole 1231 , so that the two can be stably assembled together. In addition, the assembly and disassembly methods are simple, wherein the assembly portion 1223 can be directly inserted into the locking hole 1231 or removed from the locking hole 1231. By the cooperation between the locking hole 1231 and the assembly portion 1223, the transmission element 123 can easily and effectively drive the locking block 122 to rotate.

[0148] Preferably, in this embodiment, in order to ensure the structural consistency of the transmission element 123 and avoid the impact of a protrusion and other structures on the sliding of the transmission element 123, the locking hole 1231 is provided on the transmission element 123, so that the structure of the transmission element 123 remains flat and regular, which facilitates sliding on the pull rod 112, while the assembly portion 1223 is provided on the locking block 122 to fit with the locking hole 1231.

[0149] Referring to Figure 7, Figure 9, and Figure 12, further, the inner bottom surface of the tool housing 20 is provided with a first sliding rail 21 distributed along the sliding direction of the pull rod 112, the bottom surface of the pull rod 112 is provided with a first sliding groove 1122 corresponding to the first sliding rail 21 , and the first sliding rail 21 cooperates with the first sliding groove 1122; alternatively, the inner bottom surface of the tool housing 20 is provided with a first sliding groove distributed along the sliding direction of the pull rod 112, the bottom surface of the pull rod 112 is provided with a first sliding rail corresponding to the first sliding groove, and the first sliding groove cooperates with the first sliding rail.

[0150] It can be understood that the tool housing 20 is a structure with an internal space, surrounded by a plurality of inner walls, wherein the inner bottom surface of the tool housing 20 is the bottom wall of the tool housing 20, which means that the bottom wall of the tool housing 20 is provided with a first sliding rail 21 or a first sliding groove distributed along the sliding direction of the pull rod 112, the first sliding rail 21 can be formed by upward protrusion of the bottom wall of the tool housing 20, or the first sliding groove can be formed by downward depression of the bottom wall of the tool housing20. In addition, the bottom surface of the pull rod 112 is provided with a corresponding first sliding groove 1122 or first sliding rail. The first sliding groove 1122 can be formed by inward depression of the bottom surface of the pull rod 112, or the first sliding rail can be formed by downward protrusion of the bottom surface of the pull rod 112.

[0151] The first sliding rail 21 on the tool housing 20 is slidably fitted in the first groove 1122 on the pull rod 112, or the first sliding rail 21 on the pull rod 112 is slidably fitted in the first groove 1122 on the tool housing 20. By the cooperation between the first sliding rail 21 and the first groove 1122, the tool housing 20 can receive the pull rod 112 to improve the stability of the handle body 11 when it moves, and smoothly guide the sliding of the pull rod 112, reducing the displacement of the pull rod 112 when it moves.

[0152] In one embodiment, the first sliding rail 21 or the first sliding rail 1122 is integrally formed with the tool housing 20, and the first sliding rail 1122 or the first sliding rail 21 is integrally formed with the pull rod 112, thereby improving the overall integrity of the tool housing 20 and the pull rod 112 while simplifying the production process.

[0153] Indeed, in other embodiments, the first sliding rail 21 can also be made separately from the tool housing 20 or the pull rod 112, without being subject to any specific limitations herein.

[0154] As shown in Figure 9 and Figure 12, in this embodiment, the first sliding rail 21 is provided on the inner bottom surface of the tool housing 20, and the first sliding groove 1122 is provided on the bottom surface of the pull rod 112. The first sliding rail 21 protrudes to a certain height upwards from the inner bottom surface of the tool housing 20, which means that by providing the first sliding rail 21 on the tool housing 20 to receive the pull rod 112 and the handle body 11 , the structure becomes more stable and sufficiently strong.

[0155] Referring to Figure 10 and Figure 12, further, the inner top surface of the tool housing 20 is provided with a second sliding rail 22 distributed along the sliding direction of the pull rod 112, the top surface of the pull rod 112 is provided with a second sliding groove 1123 corresponding to the second sliding rail 22, and the second sliding rail 22 cooperates with the second sliding groove 1123; alternatively, the inner top surface of the tool housing 20 is provided with a second sliding groove distributed along the sliding direction of the pull rod 112, the top surface of the pull rod 112 is provided with a second sliding rail corresponding to the second sliding groove, and the second sliding groove cooperates with the second sliding rail.

[0156] Specifically, the inner top surface of the tool housing 20 is the surface of the tool housing 20 where the locking structure 121 is located, which is the top wall of the toolhousing 20. In other words, in this embodiment, a second sliding rail 22 or a second sliding groove distributed along the sliding direction of the pull rod 112 is provided on the top wall of the tool housing 20. The second sliding rail 22 can be formed by downward protrusion of the top wall of the tool housing 20, or the second sliding groove can be formed by inward depression of the top wall of the tool housing 20. In addition, the top surface of the pull rod 112 is provided with a corresponding second groove 1123 or second sliding rail. The second groove 1123 can be formed by downward depression of the top surface of the pull rod 112, or the second sliding rail can be formed by upward protrusion of the top surface of the pull rod 112.

[0157] The second sliding rail 22 on the tool housing 20 is slidably fitted in the second groove 1123 on the pull rod 112, or the second sliding rail on the pull rod 112 is slidably fitted in the second groove on the tool housing 20. By the cooperation between the second sliding rail 22 and the second groove 1123, the pull rod 112 is guided to slide smoothly, which reduces the displacement of the pull rod 112 when it moves.

[0158] In addition, the cooperation between the first sliding groove 1122 below the pull rod 112 and the first sliding rail 21 , in conjunction with the cooperation between the second sliding groove 1123 above the pull rod 112 and the second sliding rail 22, provides stable guidance for both the upper and lower parts of the pull rod 112, further improving the stability of the handle body 11 when it moves in the tool housing 20 and relative to the tool housing 20, which further avoids displacement of the pull rod 112 during movement.

[0159] In one embodiment, the second sliding rail 22 or the second sliding rail is integrally formed with the tool housing 20, and the second sliding rail 1123 or the second sliding rail is integrally formed with the pull rod 112, thereby improving the overall integrity of the tool housing 20 and the pull rod 112 and simplifying the production process.

[0160] Indeed, in other embodiments, the second sliding rail 22 can also be made separately from the tool housing 20 or from the pull rod, without being subject to any specific limitations herein.

[0161] As shown in Figure 10 and Figure 12, in this embodiment, the second sliding rail 22 is arranged on the inner top surface of the tool housing 20, and the second sliding groove 1123 is arranged on the top surface of the pull rod 112. The second sliding rail 22 protrudes downwards to a certain height on the inner top surface of the tool housing 20, so that the pull rod 112 can maintain high structural flatness.

[0162] Referring to Figure 7 to Figure 9 and Figure 11 , further, the inner bottom surface of the tool housing 20 is further provided with a third sliding rail 23 distributed along thesliding direction of the pull rod 112, and the bottom surface of the locking block 122 is provided with a third sliding groove 1224 corresponding to the third sliding rail 23, wherein the third sliding rail 23 cooperates with the third sliding groove 1224; alternatively, a third sliding groove distributed along the sliding direction of the pull rod 112 is arranged on the inner bottom surface of the tool housing 20, and a third sliding rail corresponding to the third sliding groove is provided on the bottom surface of the locking block 122, wherein the third sliding groove cooperates with the third sliding rail.

[0163] Specifically, the inner bottom surface of the tool housing 20 is the bottom wall of the tool housing 20 where the first sliding rail 21 is located. In other words, in this embodiment, a third sliding rail 23 or a third groove is further provided on the bottom wall of the tool housing 20 along the sliding direction of the pull rod 112, wherein the third sliding rail 23 can be formed by upward protrusion of the bottom wall of the tool housing 20, or the third groove can be formed by downward depression of the bottom wall of the tool housing 20. In addition, the bottom of the locking block 122 is provided with a corresponding third groove 1224 or third sliding rail, wherein the third groove 1224 can be formed by inward depression of the bottom of the locking block 122, or the third sliding rail can be formed by downward protrusion of the bottom of the locking block 122.

[0164] The third sliding rail 23 on the tool housing 20 is slidably fitted in the third groove 1224 on the locking block 122, or the third sliding rail on the locking block 122 is slidably fitted in the third groove on the tool housing 20. By the cooperation between the third sliding rail 23 and the third groove 1224, the locking block 122 can be stably received, and the sliding of the locking block 122 can be smoothly guided, which reduces the displacement of the locking block 122 when it moves.

[0165] In one embodiment, the third sliding rail 23 or the third sliding rail is integrally formed with the tool housing 20, and the third sliding rail 1224 or the third sliding rail is integrally formed with the locking block 122, which improves the overall integrity of the tool housing 20 and the locking block 122 and simplifies the production process.

[0166] Indeed, in other embodiments, the third sliding rail 23 can also be made separately from the tool housing 20 or from the locking block, without being subject to any specific limitations herein.

[0167] As shown in Figure 9 and Figure 11 , in this embodiment, a third sliding rail 23 is provided on the inner bottom surface of the tool housing 20, a third sliding rail 1224 is provided at the bottom of the locking block 122, and the third sliding rail 23 is arranged parallel to the first sliding rail 21 at a distance. Specifically, the same structure can be divided into two parts, which are respectively formed into the first sliding rail 21 and thethird sliding rail 23 to guide the sliding of the pull rod 112 and the locking block 122 respectively, which can also simplify the production process.

[0168] Further, the third sliding groove 1224, besides cooperating with the third sliding rail 23 to receive and guide the sliding of the locking block 122, limits the rotation of the locking block 122, preventing the locking block 122 from rotating with an excessive amplitude to become difficult to control. By designing parameters such as the shape and size of the third sliding groove 1224, the rotation amplitude of the locking block 122 can be kept between the first and second positions.

[0169] As shown in Figure 9 and Figure 10, in this embodiment, the tool housing 20 can be divided into an upper part and a lower part. The upper part is used to arrange the locking structure 121 and the second sliding rail 22, and the second sliding rail 22 is arranged side by side with the locking structure 121. The lower part is used to arrange the first sliding rail 21 and the third sliding rail 23, and the first sliding rail 21 and the third sliding rail 23 are arranged side by side.

[0170] Referring to Figure 1 to Figure 4, further, the gripping element 111 comprises:

[0171] A gripping portion 1111 , wherein the trigger element 113 can be arranged in a pressable manner on the gripping portion 1111 ; and

[0172] A clamping portion 1112 connected to the gripping element 1111 , with an opening arranged between the gripping element 1111 and the clamping portion 1112, wherein when the handle mechanism 10 is pulled out from the tool housing 20, a clamping space is formed among the clamping portion 1112, the pull rod 112, and the tool housing 20.

[0173] Specifically, the gripping portion 1111 is the smaller part of the gripping element 111 mentioned earlier, which can mainly be used for a user to gripping, lifting, pulling, etc. The trigger element 113 is arranged in a pressable manner on the gripping element 1111 , making it easier for users to press and trigger.

[0174] Indeed, the gripping portion 1111 can also be used for clamping and hanging, depending on actual needs.

[0175] The clamping portion 1112 is the larger part of the gripping element 111 mentioned earlier, which can mainly be used to grip and hang the handle mechanism 10. The gripping portion 1111 is located above the clamping portion 1112, with an opening therebetween, making the gripping portion 1111 closer to the centre of gravity of the tool, which saves the user labour in lifting the tool by gripping the gripping portion 1111.

[0176] Indeed, the clamping portion 1112 can also be used by users for gripping, lifting, and pulling, depending on actual needs.

[0177] A clamping space is formed among the clamping portion 1112, the pull rod 112, and the tool housing 20. By pushing and pulling the pull rod 112, the size of the clamping space is adjustable to accommodate objects of different volumes. When in use, an object is insertable into the clamping space or placeable into the clamping space, and the pull rod 112 is pushed so that the clamping portion 1112, the pull rod 112, and the tool housing 20 wrap and clamp the object, thereby clamping, hanging, and fixing the tool.

[0178] Referring to Figure 1 , Figure 2, Figure 7, and 8, further, on the side of the clamping portion 1112 facing the tool housing 20, a buffer element 114 is further arranged, which is distributed along the width direction of the clamping portion 1112.

[0179] Specifically, the buffer element 114 can be made of a deformable material, for example, sponge, silicone, or rubber, and can be directly attached or otherwise fixed to the side of the clamping portion 1112 facing the tool housing 20, that is, on the inner side of the clamping portion 1112 facing the tool housing 20, wherein the width direction of the clamping portion 1112 is the vertical direction, which can avoid impact on the horizontal gripping portion 1111. The buffer element 114 is configured to provide a buffering effect between the clamping portion 1112 and the tool housing 20, which can reduce the impact and wear between the clamping portion 1112 (the handle mechanism 10) and the tool housing 20 when it is retracted back into the tool housing 20.

[0180] As shown in Figure 8, further, two buffering elements 114 are provided, the two buffering elements 114 being arranged at both ends of the clamping portion 1112, respectively, so that the entire clamping portion 1112 can remain stable when accommodated in the tool housing 20, and a better buffering effect is provided.

[0181] Indeed, in other embodiments, the buffer 114 can also be of another quantity and can be provided in another place on the clamping portion 1112 and / or the tool housing 20, depending on specific requirements.

[0182] Referring to Figure 1 , Figure 2, Figure 5, and Figure 6, a lighting fixture 100 according to an embodiment of the present invention comprises:

[0183] A tool housing 20; and

[0184] A handle mechanism 10 according to any of the above embodiments, the handle mechanism 10 being slidably connected to the tool housing 20, the locking structure 121 being provided on the tool housing 20.

[0185] In the lighting fixture 100 of this embodiment, the beneficial effects brought by the handle mechanism 10 are described in the previous embodiments of the handle mechanism 10, and no similar details will be given again herein. The following description will focus on the lighting fixture 100.

[0186] Exemplarily, the lighting fixture 100 can be a tower lamp or an all-round lamp, and the tool housing 20 can comprise a base, a middle frame arranged on the base, and a lamp body arranged on the middle frame, wherein the base can be internally provided with structures such as a power source and a control component (controller), on which structures such as control buttons and charging ports can be provided, the top of the base can be provided with light-emitting components, such as lamp beads, and the lamp body cover can be provided with light-emitting components and is translucent. For details about other structures of the lighting fixture 100, reference may be made to the structures of related lighting fixtures 100 in the prior art, and no similar details will be given again herein.

[0187] The lighting fixture 100 is applicable outdoors, to automotive repair or in other environments. In order to improve the lighting range, this type of lighting fixture 100 can have a relatively large volume and can be placed on a flat surface for use. When it needs to be clamped or suspended for use, or when it needs to be pulled for transport and transfer, high stability is required. Therefore, it is necessary to use the handle mechanism 10 stably.

[0188] When the handle mechanism 10 is applied to the lighting fixture 100, it is slidably connected to the base, and the locking structure 121 is arranged in the base to cooperate with the handle body 11 , so that the handle body 11 has a clamping function, which provides the following advantages:

[0189] 1. The handle body 11 has a clamping function and a movable handle function, wherein the two functions are integrated;

[0190] 2. The handle body 11 and the tool housing 20 (lamp body) are integrally designed, the clamping of which observes the ergonomic principle. When the trigger element 113 is pressed with the hand, the handle body 11 can be pulled out at the same time; when the trigger element 113 is not pressed, the handle body 11 is immovable by pulling, because it is securely locked, regardless of its state;

[0191] 3. When the handle body 11 is pulled out, without the need to press the trigger element 113, the handle body 11 can be easily pushed until it is integrated with the tool housing 20. For example, it can be pushed to clamp a wooden block or an object having the shape of a round tube to achieve clamping, which prevents hand clamping to improve safety;

[0192] 4. The locking block 122 is designed on the basis of the cam principle. The further outwards it is pulled, the more tightly the locking block 122 (cam) will be locked and clamped, which improves the stability of clamping on a large object;

[0193] 5. The handle mechanism 10 achieves non-polarised clamping by polarised motion, which allows non-polarised clamping on objects with different thicknesses, such as wooden blocks or round tubes;

[0194] 6. The handle body 11 can be used as a handle and is freely movable to different positions for easy human-machine interaction.

[0195] Referring to Figure 3 to Figure 6, a portable tool 200 according to another embodiment of the present invention comprises:

[0196] A tool housing 20; and

[0197] A handle mechanism 10 according to any of the above embodiments, the handle mechanism 10 being slidably connected to the tool housing 20, the locking structure 121 being provided on the tool housing 20.

[0198] In the portable tool 200 of this embodiment, the beneficial effects brought by the handle mechanism 10 are described in the above-described embodiments of the handle mechanism 10, and no similar details will be given again herein. The following will focus on the portable tool 200.

[0199] In one embodiment, the portable tool 200 can be an inverter, and the tool housing 20 is the housing of the inverter, which can be provided with components such as a power source and a controller. It may further be provided with structures such as sockets, display screens, and operation buttons. The inverter proposed in this embodiment can perform conventional functions of a general inverter, which uses the handle mechanism 10 to carry out pulling and other functions. For details about the specific structure of the inverter, reference may be made to the structures of related inverters in the prior art, and no similar details will be given again herein.

[0200] Due to the fact that inverters are generally heavy, pulleys can be installed on the tool housing 20, for example, the four corners or two corners of its bottom. By pulling the handle mechanism 10 out of the tool housing 20 and in conjunction with the pulleys, the inverter can be moved, which makes the inverter more portable, thus reducing the burden on the user when using the inverter.

[0201] Indeed, in other embodiments, the portable tool 200 may also be another commonly used tool in daily life, for example, a suitcase or loading box, and it is not limited to the inverters mentioned above, as long as those skilled in the art apply it according to specific needs.

[0202] In addition, Figure 5 to Figure 8 show the application of the handle mechanism 10 in the lighting fixture 100. Although the structure of the portable tool 200 is not the same as that of the lighting fixture 100, the arrangements of the locking structure 121 ,the first sliding rail 21, and other structures on the tool housing 20 of the portable tool 200 are the same as those in the lighting fixture 100. On the basis of the application of the handle mechanism 10 in the lighting fixture 100 as shown in Figure 5 to Figure 8, those skilled in the art can obtain the application of the handle mechanism 10 in the portable tool 200.
