Slide rail assembly

Abstract

A slide rail assembly includes a first rail, a second rail, a working device, an operating element, and a safety lock. The working device is movably mounted to the second rail; the safety lock is linearly movable relative to the second rail; when the operating element is operated and displaced from an initial position to a first operating position, it can drive the working device to a first operating state, allowing the second rail to displace relative to the first rail from the predetermined position in a first direction; when the safety lock is activated to an unlocked state, it allows the operating element to displace from the initial position to a second operating position, thereby driving the working device to a second operating state, allowing the second rail to displace relative to the first rail from the predetermined position in the first direction and in a second direction opposite to the first direction.

Description

Technical Field

[0001] This invention relates to a slide rail mechanism, and more particularly to a slide rail assembly with a safety mechanism. Prior Technology

[0002] For example, US Patent Publication No. 12,127,673 B2 discloses a slide rail assembly comprising a first rail, a second rail, a working member, an operating member, and a stop. The working member and the stop are arranged on the second rail; the operating member can be used to operate the working member; when the second rail is in a predetermined position relative to the first rail and the working member is in a first state, the working member and the first rail mutually block each other through a blocking feature to prevent the second rail from displacing from the predetermined position in a predetermined direction; when the stop is in a blocking state, the stop will block the operating member, preventing the operating member from driving the working member; when the stop is in an unblocking state, the stop will not block the operating member, allowing the operating member to drive the working member from the first state to a second state.

[0003] However, with varying market demands, how to develop a different slide rail product to meet the needs of the market or users has become a topic worth exploring. Summary of the Invention

[0004] This invention relates to a slide rail assembly with a safety mechanism.

[0005] According to one aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a working device, an operating member, and a safety mechanism. The first rail is provided with a stop; the second rail is longitudinally displaceable relative to the first rail; the working device is movably mounted to the second rail; the operating member is longitudinally displaceable relative to the second rail, and the operating member can be in one of an initial position, a first operating position, and a second operating position relative to the second rail, the first operating position being between the initial position and the second operating position; the safety mechanism is arranged to the second rail, and the safety mechanism includes a safety lock and an elastic member, the safety lock being linearly movable relative to the second rail; wherein, when the safety lock is in a locked state, the safety lock prevents the operating member from displacing to the second operating position; wherein, when the second rail is in a predetermined position relative to the first rail, the working device in an initial working state and the stop block each other to prevent the second rail from displacing from the predetermined position in a first direction and a second direction opposite to the first direction; wherein, when the operating member is in a locked state, the first operating position is movable relative to the second rail; wherein, when the first operating position is movable relative to the second rail, the second operating position is movable relative to the second rail; wherein, when the second operating device is in a locked state ... When the operating member is operated to move from the initial position to the first operating position, the operating member drives the working device from the initial operating state to a first operating state, allowing the second rail to move from the predetermined position in the first direction; wherein, when the safety lock is operated to move linearly from the locked state to an unlocked state, the operating member is allowed to move from the initial position to the second operating position; wherein, when the safety lock is in the unlocked state, the elastic member accumulates a spring force; wherein, during the process of the operating member being operated to move from the initial position to the second operating position, the operating member drives the working device from the initial operating state to a second operating state, allowing the second rail to move from the predetermined position in the first and second directions; wherein, when the operating member returns from the second operating position to the initial position, the safety lock returns to the locked state by releasing the spring force from the unlocked state.

[0006] According to another aspect of the present invention, a slide rail assembly includes a first rail, a second rail, a working device, an operating member, and a safety mechanism. The first rail is provided with a stop; the second rail is longitudinally displaceable relative to the first rail; the working device is movably mounted to the second rail; the operating member is movably mounted to the second rail, and the operating member can be in one of an initial position, a first operating position, and a second operating position relative to the second rail; the safety mechanism is arranged to the second rail, and the safety mechanism includes a safety lock, which is linearly movable relative to the second rail; wherein, when the safety lock is in a locked state, the safety lock blocks the movement path of the operating member to the second operating position; wherein, when the second rail is in a predetermined position relative to the first rail, the working device in an initial working state and the stop mutually block each other to prevent the second rail from displacing from the predetermined position in a first direction and a second direction opposite to the first direction; wherein, when the operating member is... When the operating member is moved from the initial position to the first operating position, it drives the working device from the initial operating state to the first operating state, allowing the second rail to move from the predetermined position in the first direction. The safety lock, in the locked state, stops the operating member at the first operating position. When the safety lock is operated to move from the locked state to the unlocked state, the safety lock no longer obstructs the path of the operating member to the second operating position, allowing the operating member to move from the initial position to the second operating position. During the process of the operating member being operated to move from the initial position to the second operating position, the operating member drives the working device from the initial operating state to the second operating state, allowing the second rail to move from the predetermined position in both the first and second directions.

[0007] Overall, the safety lock can move linearly relative to the second rail. Furthermore, the safety lock provides greater safety for the slide rail assembly during use. Simple Explanation of the Diagram

[0020] As shown in Figures 1 to 3, a slide rail assembly 20 according to a first embodiment of the present invention includes a first rail 22, a second rail 24, a working device 26, an operating member 28, and a safety mechanism 30. The second rail 24 and the first rail 22 are longitudinally displaceable relative to each other. Here, the X-axis direction is longitudinal (the length direction or displacement direction of the slide rail), the Y-axis direction is transverse (the lateral direction of the slide rail), and the Z-axis direction is vertical (the height direction of the slide rail). Preferably, it further includes a third rail (not shown), and the first rail 22 (e.g., the middle rail) is movably mounted between the third rail (e.g., the outer rail) and the second rail 24 (e.g., the inner rail).

[0021] The first rail 22 has a first end 22a and a second end 22b (e.g., a front end and a rear end, but this is not a limitation in implementation) that are positioned opposite each other. Furthermore, the first rail 22 includes a channel 32 for receiving and movably mounting the second rail 24. The first rail 22 is provided with a stop 34 (as shown in FIG. 2), preferably located within the channel 32 and adjacent to the first end 22a of the first rail 22. On the other hand, the second rail 24 has a first end 24a and a second end 24b (e.g., a front end and a rear end, but this is not a limitation in implementation).

[0022] The working device 26 is movably mounted to the second rail 24 (as shown in Figure 2). Here, the working device 26 includes at least one working component; for example, a first working component 36 and a second working component 38 are pivotally connected to the second rail 24 via a first shaft 40 and a second shaft 42, respectively. Preferably, the slide rail assembly 20 further includes an auxiliary elastic member 44 for providing elastic force to the first working component 36 and the second working component 38. For example, the auxiliary elastic member 44 is connected (e.g., fixed) to the second rail 24. The auxiliary elastic member 44 is a base having a first elastic portion 46a and a second elastic portion 46b, but the implementation is not limited. The first elastic portion 46a and the second elastic portion 46b are used to provide elastic force to the first working component 36 and the second working component 38, respectively.

[0023] The operating element 28 is movably mounted to the second rail 24, and furthermore, the operating element 28 is longitudinally displaceable relative to the second rail 24. Preferably, the operating element 28 has an operating portion 48 and at least one driving portion, such as a first driving portion 51 and a second driving portion 52, wherein the operating portion 48 is located closer to the first end 24a of the second rail 24 than the first driving portion 51 and the second driving portion 52. In addition, the first driving portion 51 is located between the operating portion 48 and the second driving portion 52 (as shown in FIG. 2). Preferably, both the first driving portion 51 and the second driving portion 52 include a guide surface (e.g., a slope or an arc surface) for use with the first working piece 36 and the second working piece 38, respectively. Preferably, the slide rail assembly 20 further includes a return spring 53 to provide a return force to the operating member 28, wherein the two ends of the return spring 53 are respectively connected to a first predetermined portion M1 on the second rail 24 and a second predetermined portion M2 on the operating member 28 (as shown in FIG. 2). Preferably, the second rail 24 and the operating member 28 have corresponding predetermined holes 49, and the predetermined holes 49 are adjacent to the operating member 48 for the user's fingers to be inserted to facilitate applying force to the operating member 48, thereby operating the operating member 28 to drive one or both of the first working member 36 and the second working member 38 of the working device 26.

[0024] The safety mechanism 30 is arranged on the second track 24. The safety mechanism 30 includes a safety lock 54 and a resilient element 56, and preferably, it also includes an auxiliary element 58 (as shown in Figures 2 and 3).

[0025] The safety lock 54 can move linearly (or linearly) relative to the second rail 24. Preferably, the safety lock 54 can move linearly along the height direction (e.g., the Z-axis direction) of the second rail 24. Preferably, one of the safety lock 54 and the second rail 24 has a first limiting feature 60, while the other of the safety lock 54 and the second rail 24 has a second limiting feature 62 for use in conjunction with the first limiting feature 60, so that the safety lock 54 can only move linearly in the height direction relative to the second rail 24 within a limited range; furthermore, one of the first limiting feature 60 and the second limiting feature 62 is, for example, a protrusion, while the other of the first limiting feature 60 and the second limiting feature 62 is, for example, an elongated hole into which a portion of the protrusion can pass.

[0026] The elastic element 56 is, for example, an elastic seat and has at least one elastic segment for providing elastic force to the safety lock 54. Here, it is taken as an example that the elastic element 56 has a first elastic segment 66a and a second elastic segment 66b for providing elastic force to the safety lock 54, but in practice, any object with elastic capacity capable of providing elastic force to the safety lock 54 is acceptable; the implementation is not limited. Furthermore, the elastic element 56 is arranged to the second track 24.

[0027] The auxiliary component 58 can move linearly (or linearly) relative to the second rail 24. Preferably, unlike the safety lock 54, which can move linearly along the height direction (e.g., the Z-axis direction) of the second rail 24, the auxiliary component 58 can move linearly along the longitudinal or length direction (e.g., the X-axis direction) of the second rail 24, which is substantially perpendicular to the height direction.

[0028] Preferably, the auxiliary member 58 and the second rail 24 have mutually mating limiting structures, allowing the auxiliary member 58 to move linearly in the longitudinal direction only relative to the second rail 24 within a limited range. For example, one of the auxiliary member 58 and the second rail 24 has a first limiting structure 68, while the other has a second limiting structure 70. One of the first limiting structure 68 and the second limiting structure 70 is, for example, a protrusion (e.g., a nail or pin), while the other is, for example, a first extension hole into which the protrusion can pass. And / or one of the auxiliary member 58 and the second rail 24 has a third limiting structure 72, while the other has a fourth limiting structure 74. One of the third limiting structure 72 and the fourth limiting structure 74 is, for example, a second extension hole, while the other of the third limiting structure 72 and the fourth limiting structure 74 is, for example, a protrusion (e.g., a nail or pin) for inserting into a portion of the second extension hole. However, in practice, the implementation of these limiting structures is not limited to this.

[0029] The slide rail assembly 20 can be in a retracted state, in which case the second rail 24 is in a retracted position R relative to the first rail 22 (as shown in Figure 1). Alternatively, the slide rail assembly 20 can be in an extended state, in which case the second rail 24 is in a predetermined position P relative to the first rail 22, for example, an extended position (as shown in Figure 2).

[0030] As shown in Figures 2 and 3, the operating component 28 can be in an initial position K0 relative to the second rail 24; the safety lock 54 is in a locked state J1; and the auxiliary component 58 is in a first auxiliary position A1.

[0031] During the opening displacement of the second rail 24 relative to the first rail 22 to the predetermined position P, the first working member 36 of the working device 26 will first encounter the stop 34 of the first rail 22 and deflect at an angle, causing the first elastic part 46a of the auxiliary elastic member 44 to accumulate elastic force. After the first working member 36 of the working device 26 passes the stop 34 of the first rail 22, the first working member 36 of the working device 26 will release the elastic force of the first elastic part 46a of the auxiliary elastic member 44 and return to an initial working state. In short, at this time, the working device 26 in the initial working state and the stop 34 on the first rail 22 block each other to prevent the second rail 24 from displacing from the predetermined position P in a first direction D1 and a second direction D2. The first direction D1 and the second direction D2 are opposite directions, for example, a closing direction and an opening direction, respectively.

[0032] Preferably, when the second rail 24 is at the predetermined position P relative to the first rail 22, the working device 26 is in the initial working state, so that the first working piece 36 and the second working piece 38 are respectively blocked at the two opposite ends of the stop 34, such as a first end 34a and a second end 34b (front end and rear end), and form mutual obstruction with the stop 34 to prevent the second rail 24 from displacing from the predetermined position P in the first direction D1 and the second direction D2.

[0033] As shown in Figures 4 and 5, when the operating member 28 is operated to move from the initial position K0 along the second direction D2 to a first operating position K1, the operating member 28 is used to drive the working device 26 from the initial working state to a first working state, so as to allow only the second rail 24 to move relative to the first rail 22 from the predetermined position P to the first direction D1.

[0034] Specifically, when a user (who can insert a finger through the predetermined hole 49) applies a first force F1 to the operating part 48 of the operating member 28, causing the operating member 28 to move longitudinally relative to the second rail 24 from the initial position K0 to the second direction D2 to the first operating position K1, the operating member 28 drives the working device 26 from the initial working state to the first working state. For example, the first driving part 51 of the operating member 28 drives the first working part 36 of the working device 26, causing the first working part 36 to rotate in a first pivoting direction r1 (e.g., counterclockwise) to a predetermined angle and no longer block the first end 34a of the stop part 34, so that only the second rail 24 is allowed to move from the predetermined position P to the first direction D1, for example, to the retracted position R (as shown in Figure 1). On the other hand, when the working device 26 is in the first working state, the second working member 38 of the working device 26 is not yet driven by the second driving part 52 of the operating member 28 and is still blocked by the second end 34b of the stop part 34 to prevent the second rail 24 from displacing from the predetermined position P to the second direction D2 (as shown in FIG4). When the working device 26 is in the first working state, the first elastic part 46a of the auxiliary elastic member 44 is pressed by the first working member 36 and is in a state of accumulating a first auxiliary elastic force. Once the user stops applying the first force F1 to the operating member 28, the operating member 28 returns to the initial position K0 by the return force of the return spring 53, allowing the first working member 36 of the working device 26 to release the first auxiliary elastic force by the first elastic part 46a of the auxiliary elastic member 44 and return to the aforementioned initial working state.

[0035] It is worth mentioning that when the safety lock 54 is in the locked state J1, the safety lock 54 prevents the operating member 28 from moving only to the first operating position K1 (as shown in Figure 5), thus preventing the operating member 28 from continuing to move in the second direction D2 to a second operating position K2 (refer to Figure 8 for the second operating position K2). Furthermore, when the safety lock 54 is in the locked state J1, the safety lock 54 blocks the movement path of the operating member 28 from the initial position K0 or the first operating position K1 to the second operating position K2. The first operating position K1 is located between the initial position K0 and the second operating position K2.

[0036] Preferably, when the operating member 28 is in the first operating position K1, the return spring 53 is in a state of accumulating return force. Once the user stops applying the first force F1 to the operating member 28, the operating member 28 can return to the first operating position K1 from the first operating position K1 to the initial position K0 by responding to the return spring 53 to release the return force.

[0037] As shown in Figures 3 and 6, one of the auxiliary component 58 and the safety lock 54 has a guide portion 76. The guide portion 76 is, for example, a sloped surface or a curved surface. Here, it is taken as an example that both the auxiliary component 58 and the safety lock 54 have guide portions 76, but the implementation is not limited to this.

[0038] When the second rail 24 is at the predetermined position P relative to the first rail 22, the working device 26 is in the initial working state, so that the first working piece 36 and the second working piece 38 respectively block the first end 34a and the second end 34b of the stop 34 and form mutual obstruction with the stop 34, so as to prevent the second rail 24 from moving from the predetermined position P to the first direction D1 and the second direction D2 (as shown in Figure 6).

[0039] As shown in Figures 3 and 6 to 8, when the safety lock 54 is operated and moves linearly from the locked state J1 (as shown in Figure 3) to an unlocked state J2 (as shown in Figure 6) in a first height direction h1, the safety lock 54 no longer obstructs the movement path of the operating member 28 from the initial position K0 or the first operating position K1 to the second operating position D2, thereby allowing the operating member 28 to move from the initial position K0 (as shown in Figure 6) to the second operating position D2, passing through the first operating position K1 to the second operating position K2 (as shown in Figure 8).

[0040] When the operating member 28 is operated to move from the initial position K0 to the second operating position K2, the operating member 28 is used to drive the working device 26 from the initial working state to a second working state, so that the working device 26 and the stop 34 on the first rail 22 no longer block each other, so as to allow the second rail 24 to retract from the predetermined position P in the first direction D1 or move in the second direction D2 to be unloaded.

[0041] Preferably, as shown in Figures 6 to 8, when the operating member 28 is operated by the user with a second force F2 along the second direction D2 to move from the initial position K0 (as shown in Figure 6) to the second operating position K2 (as shown in Figures 7 and 8), the operating member 28 is used to drive the working device 26 from the initial working state (as shown in Figure 6) to the second working state (as shown in Figures 7 and 8). For example, the operating member 28 is used through the first driving part 51 and the second driving part 52 to drive the first working member 36 and the second working member 3 of the working device 26 respectively. 8. The first working piece 36 is rotated in the first pivoting direction r1 (e.g., counterclockwise) to a predetermined angle, and the second working piece 38 is rotated in a second pivoting direction r2 (e.g., clockwise) to another predetermined angle so that it no longer obstructs the stop 34. For example, the first working piece 36 and the second working piece 38 no longer obstruct the first end 34a and the second end 34b of the stop 34, respectively, so as to allow the second rail 24 to retract relative to the first rail 22 from the predetermined position P in the first direction D1 or to displace in the second direction D2 (as shown in Figure 7). When the working device 26 is in the second working state, the first elastic part 46a and the second elastic part 46b of the auxiliary elastic member 44 are pressed by the first working piece 36 and the second working piece 38, respectively, and are in a state of accumulating a first auxiliary elastic force and a second auxiliary elastic force.

[0042] Preferably, when the auxiliary member 58 is operated by a predetermined force F applied by the user to move linearly from the first auxiliary position A1 (as shown in FIG. 3) to a second auxiliary position A2 (as shown in FIG. 6) in the first direction D1, the auxiliary member 58 drives the safety lock 54 from the locked state J1 (as shown in FIG. 3) to the unlocked state J2 (as shown in FIG. 6), and the auxiliary member 58 blocks (e.g., presses down) the return path of the safety lock 54, so that the safety lock 54 remains in the unlocked state J2 (as shown in FIG. 6). When the safety lock 54 is in the unlocked state J2, the elastic member 56 accumulates an elastic force f (as shown in FIG. 6).

[0043] Preferably, the auxiliary component 58 is used through the guide portion 76 to contact and drive the safety lock 54 from the locked state J1 to the first height direction h1 (as shown in FIG3) to the unlocked state J2 (as shown in FIG6).

[0044] As the operating member 28 moves from the initial position K0 (as shown in Figure 6) to the second operating position K2 (as shown in Figure 8), the operating member 28 contacts and drives the auxiliary member 58 away from the second auxiliary position A2, causing the auxiliary member 58 to return to the first auxiliary position A1 in the second direction D2 (refer to Figure 3 for the first auxiliary position A1). The auxiliary member 58 no longer obstructs the return path of the safety lock 54. At this time, once the external force applied to the operating member 28 is released, the operating member 28 returns to the initial position K0 from the second operating position K2 in the first direction D1 in response to the return force of the return spring 53 (refer to Figure 3 for the initial position K0). When the safety lock 54 returns to the locked state J1 from the unlocked state J2 in the second height direction h2 (as shown in Figure 8) by the return force f released by the elastic member 56.

[0045] Preferably, specifically, when the operating member 28 is in the second operating position K2, the return spring 53 is in a state of accumulating return force (as shown in Figure 7). Once the user stops applying the second force F2 to the operating member 28, the operating member 28 can return to the initial position K0 from the second operating position K2 by responding to the return spring 53 to release the return force.

[0046] Preferably, once the user stops applying the second force F2 to the operating member 28, and the operating member 28 returns from the second operating position K2 to the initial position K0, the first working member 36 and the second working member 38 of the working device 26 respectively respond to the first elastic part 46a and the second elastic part 46b of the auxiliary elastic member 44 to release the first auxiliary elastic force and the second auxiliary elastic force and return to the above-mentioned initial working state.

[0047] As shown in Figures 8 and 3, when the operating member 28 returns from the second operating position K2 (as shown in Figure 8) to the initial position K0 (as shown in Figure 3) in the first direction D1, and the auxiliary member 58 no longer obstructs (e.g., no longer presses down) the safety lock 54, the safety lock 54 returns to the locked state J1 (as shown in Figure 3) via the elastic member 56 releasing the elastic force f from the unlocked state J2 (as shown in Figure 8) to the second height direction h2 along the return path. The second height direction h2 is opposite to the first height direction h1.

[0048] As shown in Figures 7 and 9, once the working device 26 is in the second working state, the second rail 24 is allowed to move relative to the first rail 22 from the predetermined position P to the second direction D2, so that the second rail 24 can be detached from the channel 32 of the first rail 22. That is, through the safety mechanism 30, the user can selectively move the operating member 28 to the first operating position K1 or the second operating position K2 as needed. Only when the operating member 28 is moved to the second operating position K2 can the working device 26 be driven to move to the second working state, so that the second rail 24 can be detached from the channel 32 of the first rail 22. Therefore, the slide rail assembly 20 is safe and reliable in use, avoiding unexpected operational errors that could cause the slide rail and the load attached to the slide rail to fall. Furthermore, when the slide rail assembly 20 is installed in a rack (cabinet) and the second rail 24 carries a load (such as electronic equipment), the safety mechanism 30 can prevent the operating element 28 from being operated to the second operating position K2 unintentionally or unintentionally, and can prevent the working device 26 from moving to the second working state, so that the second rail 24 cannot be arbitrarily removed from the channel 32 of the first rail 22, thereby making the slide rail assembly 20 safe or reliable in use.

[0049] Figures 10 and 11 illustrate the elastic element 201 of the second embodiment of the present invention. The difference between this elastic element and the elastic element 56 of the first embodiment, which is an elastic seat, is that this elastic element 201 is a spring, which can also be used to provide elastic force to the safety lock 202. Preferably, the two ends of the elastic element 201 are respectively used to connect to a first corresponding portion 204 on the second rail 24 and a second corresponding portion 206 on the safety lock 202.

[0050] Furthermore, the safety lock 202 can also move linearly relative to the second rail 208 from a first state J1' (as shown in Figure 10) to a second state J2' (as shown in Figure 11) in a first height direction h1'; or, in response to the release of the elastic force of the elastic member 201, it can return from the second state J2' to the first state J1' in a second height direction h2'. In the first state J1', the safety lock 202 can be used to block the movement path of the operating member 210 from the initial position K0' or the first operating position to the second operating position in the second direction D2; or, in the second state J2', the safety lock 202 no longer blocks the movement path of the operating member 210 from the initial position K0' or the first operating position to the second operating position in the second direction D2.

[0051] Preferably, during the process of the auxiliary member 212 moving from the first auxiliary position A1' (as shown in FIG. 10) to the second auxiliary position A2' (as shown in FIG. 11) in the first direction D1, the auxiliary member 212 can be used through the guide part 214 (e.g., a slope or arc surface) to drive the safety lock 202 from the first state J1' to the second state J2' in the first height direction h1'.

[0052] Similar to the first embodiment, this second embodiment can also achieve the goal of making the slide rail assembly 200 safe to use.

[0053] Therefore, the slide rail assembly 20 of the embodiment of the present invention includes the following features:

[0054] 1. When the safety lock 54 is in the locked state J1, the operating member 28 can only be moved from the initial position K0 to the first operating position K1, so as to drive the first working member 36 of the working device 26 to no longer block the first end 34a of the stop 34. Accordingly, only the second rail 24 is allowed to move relative to the first rail 22 from the predetermined position P to the first direction D1 (i.e., close). When the safety lock 54 is in the unlocked state J2, the operating member 28 can be moved from the initial position K0 to the second operating position K2, so as to drive the first working member 36 and the second working member 38 of the working device 26 to no longer block the first end 34a and the second end 34b of the stop 34, so as to allow the second rail 24 to move relative to the first rail 22 from the predetermined position P to the first direction D1 or the second direction D2 (e.g., unload the slide rail). Furthermore, the safety lock 54 of the safety mechanism 30 allows the user to selectively move the operating element 28 from the initial position K0 or the first operating position K1 to the second operating position K2 as needed. This allows the operating element 28 to drive the working device 26 to the second working state, so that the second rail 24 can move from the predetermined position P to the second direction D2, thereby allowing the second rail 24 to be unloaded from the channel 32 of the first rail 22. Therefore, the slide rail assembly 20 is safer and more reliable in use.

[0055] 2. The safety lock 54 can move linearly relative to the second rail 24, thus meeting different market or user needs and providing better reliability of the blocking.

[0056] 3. During the process of the operating member 28 moving from the initial position K0 or the first operating position K1 to the second operating position D2, the operating member 28 can contact and drive the auxiliary member 58 from the second auxiliary position A2 to the first auxiliary position A1 from the second auxiliary position A2 to the second operating position D2, and the auxiliary member 58 no longer obstructs (e.g., no longer presses down) the safety lock 54. At this time, once the operating member 28 returns from the second operating position K2 to the initial position K0 from the first operating position D1, the safety lock 54 responds to the elastic member 56 to release the elastic force f from the unlocked state J2 to the second height direction h2 and return to the locked state J1.

[0057] 4. The first working part 36 and the second working part 38 of the working device 26 can be operated by the first drive part 51 and the second drive part 52 of the operating part 28 respectively, thus meeting the different needs of the market or users.

[0058] 5. The auxiliary component 58 and the safety lock 54 can move linearly (or in a straight line) relative to the second rail 24 in different directions, so that the actuation relationship between them has clear reliability.

[0059] Although the present invention has been disclosed with reference to the foregoing preferred embodiments, it is not intended to limit the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
