The mounting mechanism 46 further includes an operating device 94, the operating device 94 including a linkage 96 and a resilient member 98. The elastic member 98 can provide elastic force to load the movable member 52 by the connecting rod 96. In particular, the link 96 has a head portion 100 and a body portion 102 connected to the head portion 100, the body portion 102 partially extending through the mounting feature 60 of the extension wall 58; the resilient member 98 can be disposed through the body portion 102 and abut between the extension wall 58 and the head portion 100. In addition, a first linking member 104 and a second linking member 106 are movably disposed between the link 96 and the transmission device 50. In detail, the second supporting member 64 is disposed for the first linking member 104 to pass through, so that the first linking member 104 can pivot relative to the base 48. The first linkage member 104 includes a plurality of teeth 108 that are capable of intermeshing with the transmission 50. The second linking member 106 is movably connected between the connecting rod 96 and the first linking member 104. The second linking member 106 is connected to the first linking member 104 by a first connecting member 110, and the second linking member 106 is connected to the head 100 of the connecting rod 96 by a second connecting member 112. Preferably, the second linking member 106 includes a manual portion 114 for an operator to manually adjust the second linking member 106 by a tool.

As shown in fig. 6, the transmission device 50 is inserted through a first support 62 on the base 48. The transmission device 50 includes a first transmission member 68 and a second transmission member 70. The first transmission member 68 and the second transmission member 70 may be integrally formed; alternatively, the first transmission member 68 and the second transmission member 70 may be two independent components and connected together by a connection means, such as, but not limited to, snap-fit, or adhesive. The first transmission member 68 has a first plurality of teeth 72, and the second transmission member 70 has a second plurality of teeth 76.

As shown in fig. 7, the first member 40 includes a first longitudinal wall 116a, a second longitudinal wall 116b, and a transverse wall 118 connected between the two longitudinal walls 116a, 116 b. Preferably, an auxiliary portion 120 is connected between the two longitudinal walls 116a, 116b, and a first adjustment member 122 is disposed on one of the two longitudinal walls 116a, 116 b. As shown in fig. 7 in conjunction with fig. 2, wherein the transverse wall 118 can be connected to the panel 36 of the carrier 24.

As shown in fig. 8 and 9, when the protrusion 66 corresponds to the second channel 88 of the movable member 52, the movable member 52 is temporarily located at a first position P1 relative to the base 48. In this state, the movable member 52 is inclined with respect to the base 48; on the other hand, the transmission device 50, the first linking member 104, the second linking member 106, the connecting rod 96 and the elastic member 98 are respectively in a predetermined state relative to the movable member 52. The elastic member 98 can store an elastic force in the predetermined state, but is not limited in implementation. As shown in fig. 8 and fig. 2, when the panel 36 of the supporting object 24 is to be mounted on the sidewall 34, an operator can move the first member 40 on the panel 36 toward a direction D, and during the movement toward the direction D, the auxiliary portion 120 of the first member 40 pushes against the guide surface 92 of the movable member 52.

As shown in fig. 10 and 11, when the auxiliary portion 120 of the first member 40 continuously pushes against the guide surface 92 of the movable member 52 in the direction D, the movable member 52 is displaced from the first position P1 in the direction D, so that the protruding element 66 can correspond to the first passage 86 of the movable member 52, in which state the movable member 52 is no longer inclined relative to the base 48, and the movable member 52 can be installed on the first member 40. In this embodiment, the first member 40 is snap-mounted to the snap section 90 of the movable member 52 by the auxiliary portion 120; on the other hand, the rack 78 of the movable member 52 drives the first transmission member 68 of the transmission device 50, and the second transmission member 70 drives the first linkage member 104, the second linkage member 106, and the connecting rod 96 in response to the transmission of the first transmission member 68. When the connecting rod 96 is driven to a position from the predetermined state, the movable member 52 releases an elastic force by the elastic member 98 to be automatically displaced from the first position P1 to a second position P2 relative to the base 48, and in the process, the movable member 52 is movably displaced toward the second position P2 in the direction D (as shown in fig. 10) by the engagement of the rack 78 and the first transmission member 68 of the transmission device 50 until the movable member 52 reaches the second position P2 (as shown in fig. 11), and the first member 40 is firmly mounted on the second member 44. That is, the transmission device 50 is responsive to the snap section 90 of the first member 40 being mounted to the snap portion 84 of the moveable member 52 for moving the moveable member 52 from a first position to a second position.

When the first member 40 is to be detached from the second member 44, an operator may insert a tool, such as a screwdriver, into the manual portion 114 of the second linking member 106 to manually adjust the movement of the second linking member 106, so as to link the link 96, the first linking member 104, the transmission device 50, and the movable member 52, such that the movable member 52 can be movably displaced from the second position P2 toward the first position P1 in another direction opposite to the direction D relative to the base 48 until the movable member 52 is displaced to the first position P1, and the auxiliary portion 120 on the first member 40 can be released from the latching section 90 of the latching portion 84 of the movable member 52 (as for the operation principle of this portion, fig. 11, 10, 9, and 8 are sequentially referred to, and are not further described herein for brevity).

As shown in FIG. 12, the first member 40 can be mounted to the moveable member 52 and the housing 54 can be closed over the base 48. In addition, the first adjustment element 122 disposed on the first component 40 includes an adjustment portion 124, an abutting portion 126, and a thread feature 128 connected between the adjustment portion 124 and the abutting portion 126. The adjusting portion 124 can correspond to a first operation hole 130 of the housing 54; the pushing portion 126 can pass through the two longitudinal walls 116a, 116b and correspond to the base 48. Preferably, the mounting mechanism 46 further includes a second adjustment member 132 mounted to the base 48, such that an operator can adjust the second adjustment member 132 from a second aperture 134 of the housing 54.

As shown in fig. 13 and 14, a lateral position of the panel 36 can be adjusted by the first adjusting member 122 disposed on the first member 40. Specifically, one of the two longitudinal walls 116a, 116b of the first member 40 has a boss 136, and the boss 136 has a threaded feature (e.g., an internal threaded feature, not shown). When the operator adjusts the first adjusting member 122 through the first operation hole 130 of the housing 54, the first member 40 and the panel 36 can be displaced in the transverse direction (or in the lateral direction) by the corresponding screwing relationship between the screw feature 128 of the first adjusting member 122 and the screw feature of the boss 136, that is, the transverse position (or in the lateral direction) of the panel 36 relative to the base 48, the second member 44 or the side wall can be adjusted.

As shown in fig. 15, the base 48 has a plurality of first holes 138 and a second hole 140, and the hole-shaped direction of the second hole 140 is substantially perpendicular to the hole-shaped direction of each of the first holes 138. Herein, the hole shape direction of each first hole 138 is arranged in a straight direction, and the hole shape direction of each second hole 140 is arranged in a longitudinal direction. The mounting mechanism also includes a plurality of guides 142. Each guide 142 corresponds to each first hole 138. Specifically, each guide 142 has a connecting portion 144 and a blocking portion 146 connected to the connecting portion 144. The connecting portion 144 of each guide 142 can pass through the first hole 138 of the base 48 to connect to the second member 44, and the blocking portion 146 of each guide 142 blocks one side of the base 48. The connecting portion 144 of each guide 142 is smaller than the length of each first hole 138, so that the base 48 can be movably mounted to the second member 44.

As shown in fig. 15 and 16, the second adjusting element 132 includes an adjusting portion 148, a pivoting portion 150, and an eccentric portion 152 connected between the adjusting portion 148 and the pivoting portion 150. The adjusting portion 148 and the pivoting portion 150 have the same axis. On the other hand, the eccentric portion 152 is deviated from the axial center, that is, the center of the eccentric portion 152 is deviated from the center of the adjusting portion 148 and the pivot portion 150. Preferably, the second adjustment member 132 further includes a stop 154 that stops on one side of the base 48. Wherein the pivot portion 150 passes through the second hole 140 of the base 48 and is pivotally connected to the second member 44; the eccentric portion 152 may correspond to the second hole 140 of the base 48.

As shown in fig. 17, 18 and 19, the base 48 can be movably displaced upward or downward relative to the second member 44 by adjusting the second adjusting member 132. Specifically, when the operator adjusts the adjusting portion 148, the eccentric portion 152 can push against an upper wall 156a or a lower wall 156b adjacent to the second hole 140 of the base 48, so that the base 48 can be movably displaced from the state of fig. 18 (see fig. 19) or the state of fig. 17 (see fig. 17) to the second member 44 according to the straight hole shape of the first hole 138. Referring to fig. 20, when the panel is mounted to the movable member 52 on the base 48 by the first member 40, the position of the base 48 can be adjusted upward or downward, so that the panel can be adjusted upward or downward relative to the second member 44 or the sidewall 34.

As shown in FIGS. 20 and 21, the mounting mechanism 46 of one embodiment of the present invention can include a retaining wall 158 that is connected to the base 48. The retaining wall 158 is adjacent to the second linking member 106. When the first member 40 is mounted to the second member 44 and an external force F is forcibly applied to the first member 40 in another direction opposite to the direction D, the movable member 52 is pulled by the external force F together with the first member 40, so as to link the transmission device 50, the first linking member 104 and the second linking member 106. That is, the second linking member 106 is linked and blocked at the blocking wall 158 in response to the external force F, so that the first member 40 cannot be pulled out relative to the second member 44. Accordingly, the reliability of the first member 40 being mounted on the second member 44 can be improved.

As shown in fig. 22 and 23, the mounting mechanism includes a stop feature 160, such as a retaining wall, that can be disposed on the base 48. When the second linking component 106 is in a predetermined state and located at a position (referring to the state of the second linking component 106 in fig. 8 and 9 for the predetermined state), the position of the manual portion 114 of the second linking component 106 is corresponding to the position of the blocking feature 160 of the base 48, so that when a tool, such as a screwdriver (not shown), is inserted into the manual portion 114 of the second linking component 106, the front end of the tool is blocked by the blocking feature 160 of the base 48 when the tool rotates, so that the screwdriver cannot rotate the second linking component 106, thereby ensuring that the related components of the first linking component 104 and the connecting rod 96 can be kept in the predetermined state relative to the second linking component 106.
