[0053] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the description of the present application in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0055] Spatial relationship terms such as "under", "below", "beneath", "underneath", "above", "over", etc. can be used herein to describe the relationship of one element or feature shown in the figure with other elements or features. Meanwhile, for example, "directly above" can be used herein to describe that one element or feature shown in the figure coincides in the vertical line direction, where it can be partially coincident or completely coincident, specifically determined according to the actual situation or the content shown in the figure. It should be understood that in addition to the orientations shown in the figure, spatial relationship terms also include different orientations of the device during use and operation. For example, if the device in the attached drawing is flipped, the element or feature described as "under other elements" or "beneath it" or "under it" will be oriented "above" other elements or features. Therefore, the exemplary terms "under" and "beneath" can include both the upper and lower orientations. In addition, the device can also include other orientations (such as rotating 90 degrees or other orientations), and the spatial descriptors used herein are accordingly interpreted.

[0056] It should be noted that when an element is referred to as "fixedly connected" to another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes.

[0057] As used herein, the singular forms of "a", "an" and "the" may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms "comprising" or "having" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0058] In a first aspect, an embodiment of the present invention provides a locking structure, in combination with Figure 1 and Figure 2 , the locking structure includes: a support frame 1, a guide sleeve 2, a drive rod 3, a locking member 4 and a transmission mechanism 5.

[0059] In combination with Figure 3 and Figure 4 , a through hole 11 is formed in the support frame 1, the through hole 11 is adapted to the locking member 4, and the locking member 4 can be movably connected to the support frame 1 along a first direction through the through hole 11.

[0060] The driving rod 3 can slide relative to the support frame 1 in the second direction, and the first direction intersects with the second direction. The guide sleeve 2 is connected to the transmission mechanism 5 and forms a guiding environment with the driving rod 3. The driving rod 3 drives the guide sleeve 2 to swing between the first extreme position and the second extreme position through the guiding environment. The transmission mechanism 5 is connected to the locking member 4, and the guide sleeve 2 drives the locking member 4 to move between the locking position and the unlocking position through the transmission mechanism 5.

[0061] It can be seen that the guide sleeve 2 can convert the translation of the driving rod 3 in the second direction into rotation in the second direction, and the transmission mechanism 5 converts the rotation of the guide sleeve 2 in the second direction into translation in the first direction.

[0062] Among them, when the guide sleeve 2 is in the first extreme position, the locking member 4 passes through the support frame 1 through the through hole 11; when the guide sleeve 2 is in the second extreme position, the locking member 4 does not pass through the support frame 1.

[0063] It can be understood that when the guide sleeve 2 is in the second extreme position, the locking member 4 does not pass through the surface of the support frame 1. One end of the locking member 4 used to extend out of the support frame 1 through the through hole 11 is located inside the through hole 11 and does not extend out of the support frame 1, or one end of the locking member 4 used to extend out of the support frame 1 through the through hole 11 is not inserted into the through hole 11. Further, one end of the locking member 4 used to extend out of the support frame 1 through the through hole 11 can always be inserted into the support frame 1, that is, whether the locking member 4 is in the locking position or the unlocking position, the locking member 4 is inserted into the support frame 1 through the through hole 11, or it can be separated from the support frame 1 when the locking member 4 is in the unlocking position, that is, the locking member 4 and the support frame 1 are in a separated state.

[0064] In this embodiment, the support frame 1 is a box structure, and the guide sleeve 2, the driving rod 3 and the transmission mechanism 5 are all located in the internal space formed by the support frame 1; the first direction is perpendicular to the second direction, where the first direction is the up-down direction and the second direction is the front-back direction; the top end of the locking member 4 is always inserted into the support frame 1 through the through hole 11.

[0065] The locking structure provided by the embodiment of the present invention can switch the locking member 4 between the locking position and the unlocking position by setting the guide sleeve 2, the driving rod 3 and the transmission mechanism 5. When the locking member 4 is in the locking position, one end of it extends out of the support frame 1 and can be inserted into the external frame 100, thereby blocking the support frame 1 from moving in the second direction on the frame 100, and further realizing the fixation of the support frame 1 relative to the frame 100. When the locking member 4 is in the unlocking position, one end of it does not extend out of the support frame 1, so that the locking member 4 is separated from the external frame 100, and the support frame 1 can move relative to the frame 100 in the second direction, thereby realizing the pulling of the support frame 1 relative to the frame 100. This locking structure is simple to operate and convenient to disassemble and assemble with the external frame 100.

[0066] Combined withFigure 1 and Figure 5 The guide sleeve 2 is sleeved on the driving rod 3 along the second direction and is rotatably connected to the driving rod 3. The guiding environment includes: a guiding boss 61 and a spiral chute 62.

[0067] The guiding boss 61 is adapted to the spiral chute 62. The guiding boss 61 and the spiral chute 62 are respectively arranged on the driving rod 3 and the guide sleeve 2. The spiral chute 62 spirally extends along the second direction. The guiding boss 61 is inserted into the spiral chute 62 and can slide along the spiral chute 62.

[0068] It should be noted that the guiding boss 61 and the spiral chute 62 are respectively arranged on the driving rod 3 and the guide sleeve 2, which means that when the guiding boss 61 is arranged on the driving rod 3, the spiral chute 62 is arranged on the guide sleeve 2; when the guiding boss 61 is arranged on the guide sleeve 2, the spiral chute 62 is arranged on the driving rod 3. Among them, the driving rod 3 is sleeved with the guide sleeve 2, such as the driving rod 3 is sleeved on the outer peripheral side of the guide sleeve 2, or the guide sleeve 2 is sleeved on the outer peripheral side of the driving rod 3.

[0069] In this embodiment, the guide sleeve 2 is sleeved on the outer peripheral side of the driving rod 3 and is rotatably connected to the driving rod 3. The guiding boss 61 is fixed on the outer side wall of the driving rod 3, the spiral chute 62 is formed on the inner side wall of the guide sleeve 2, and the guiding boss 61 is slidably connected to the guide sleeve 2 through the spiral chute 62.

[0070] Among them, the spiral chute 62 may not penetrate the end face of the guide sleeve 2, or at least one end may penetrate the end face of the guide sleeve 2; the angle at which the guiding boss 61 slides along the spiral chute 62 determines the angle at which the guide sleeve 2 rotates relative to the driving rod 3. In this embodiment, the spiral chute 62 rotates clockwise from front to back, and the front end of the spiral chute 62 penetrates the left part of the front end face of the guide sleeve 2, and the rear end of the spiral chute 62 penetrates the right part of the rear end face of the guide sleeve 2. Thus, when the guiding boss 61 moves from the front end face of the guiding boss 61 to the rear end face, the guide sleeve 2 will rotate counterclockwise by 180 degrees; when the guiding boss 61 moves from the rear end face of the guiding boss 61 to the front end face, the guide sleeve 2 will rotate clockwise by 180 degrees.

[0071] By arranging the guiding boss 61 and the spiral chute 62, it can be ensured that the guide sleeve 2 can stably drive the driving rod 3 to translate along the second direction and rotate along the second direction at the same time, so as to control the locking member 4 to flexibly switch between the locking position and the unlocking position. Among them, the driving rod 3 rotates along the second direction, which can be understood as the driving rod 3 rotates in the circumferential direction of the guide sleeve 2.

[0072] Combined with Figure 1 、 Figure 2 and Figure 6 The transmission mechanism 5 includes: a link assembly 51 and a slider 52.

[0073] The slider 52 is slidably connected to the support frame 1 along the third direction, and the second direction is perpendicular to the third direction. One end of the connecting rod assembly 51 is movably connected to the slider 52, the other end of the connecting rod assembly 51 is fixedly connected to the guide sleeve 2, and the locking member 4 is connected to the slider 52.

[0074] The guide sleeve 2 drives the slider 52 to move along the third direction through the connecting rod assembly 51, so that the locking member 4 moves between the locking position and the unlocking position. Wherein, the locking member 4 can be fixedly connected to the slider 52 or movably connected to the slider 52; the third direction can be parallel or intersect with the first direction.

[0075] In this embodiment, the locking member 4 is movably connected to the slider 52. Specifically, in combination with Figure 1 and Figure 7 , a slant groove 521 is formed on the slider 52, and an L-shaped sliding groove 12 is formed on the inner side wall of the rear end of the support frame 1. The first direction is perpendicular to the third direction. In this embodiment, the third direction is perpendicular to the first direction, and the third direction is the left-right direction.

[0076] Wherein, the L-shaped sliding groove 12 includes a horizontal portion 121 and a vertical portion 122. The vertical portion 122 extends along the first direction, the horizontal portion 121 extends along the third direction, one end of the horizontal portion 121 is communicated with one end of the vertical portion 122, and the other end of the horizontal portion 121 extends towards the guide sleeve 2.

[0077] The bottom end of the locking member 4 is slidably connected to the slider 52 and the support frame 1 respectively through the slant groove 521 and the L-shaped sliding groove 12, and the top end of the locking member 4 is used to pass through the support frame 1 through the through hole 11. In this embodiment, in combination with Figure 1 and Figure 6 , a travel shaft 63 is fixedly arranged at the bottom end of the locking member 4, and the locking member 4 is slidably connected to the slider 52 and the support frame 1 respectively through the travel shaft 63. Specifically, one end of the travel shaft 63 is fixedly connected to the bottom end of the locking member 4, and the other end of the travel shaft 63 extends horizontally backward and passes through the slider 52 through the slant groove 521 and is inserted into the L-shaped sliding groove 12.

[0078] Wherein, the low end of the slant groove 521 coincides with the horizontal portion 121 in the horizontal direction, and the top end of the slant groove 521 coincides with the top end of the vertical portion 122 in the horizontal direction; the bottom end of the locking member 4 is located at the top end of the vertical portion 122 when the guide sleeve 2 is at the first extreme position; the bottom end of the locking member 4 is located at the end of the horizontal portion 121 away from the vertical portion 122 when the guide sleeve 2 is at the second extreme position.

[0079] In a further optional embodiment of this embodiment, the locking structure further includes: a spacer post 64. The spacer post 64 is sleeved on the outer peripheral side of the stroke shaft 63 and fixedly connected to the stroke shaft 63. The spacer post 64 is located between the locking member 4 and the slider 52. By providing the spacer post 64, it effectively prevents the slider 52 from wearing the locking member 4 during the sliding of the locking member 4 relative to the slider 52.

[0080] Further, the link assembly 51 includes: a first link 511 and a second link 512. Wherein, one end of the first link 511 is fixedly connected to the guide sleeve 2, the other end of the first link 511 is pivotally connected to the second link 512, the other end of the second link 512 is pivotally connected to the slider 52, and the length of the second link 512 is greater than the length of the first link 511.

[0081] When the guide sleeve 2 is at the first extreme position, both the first link 511 and the second link 512 extend in the left-right direction, and the distance between the end of the first link 511 connected to the guide sleeve 2 and the end of the second link 512 connected to the slider 52 is the largest; when the guide sleeve 2 is at the second extreme position, both the first link 511 and the second link 512 extend in the left-right direction, and the distance between the end of the first link 511 connected to the guide sleeve 2 and the end of the second link 512 connected to the slider 52 is the smallest.

[0082] Further, in combination with Figure 3 and Figure 4 , the opening of the through hole 11 extends in the third direction. By defining the opening of the through hole 11, it can ensure that the locking member 4 is always inserted into the support frame 1 through the through hole 11 when the guide sleeve 2 swings between the first extreme position and the second extreme position, thereby improving the stability of the locking structure.

[0083] In this embodiment, in combination with Figure 1 and Figure 2 , the number of the locking members 4 and the transmission mechanisms 5 is two. The two locking members 4 and the two transmission mechanisms 5 are arranged in mirror symmetry. It can be understood that the two transmission mechanisms 5 can respectively drive the two locking members 4 to move synchronously between the locking position and the unlocking position through a guide sleeve 2 and a driving rod 3, or can jointly drive the two locking members 4 to move synchronously between the locking position and the unlocking position through a guide sleeve 2 and a driving rod 3.

[0084] In this embodiment, the two transmission mechanisms 5 jointly drive the two locking members 4 to move synchronously between the locking position and the unlocking position through a guide sleeve 2 and a driving rod 3.

[0085] Specifically, the locking structure further includes a driving mechanism 7. The driving mechanism 7 is respectively connected to the two transmission mechanisms 5 and is used to drive one locking member 4 and the other locking member 4 to move synchronously between the locking position and the unlocking position.

[0086] Furthermore, the driving mechanism 7 includes: a driving wheel 71, a driven wheel 72, a conveyor belt 73, and a support shaft 74. The driving wheel 71 and the driven wheel 72 have the same radius and are arranged in the left-right direction. The driving wheel 71 is fixedly connected to the guiding sleeve 2, the driven wheel 72 is fixedly connected to the support shaft 74, the support shaft 74 is rotatably connected to the support frame 1, one end of a transmission mechanism 5 is fixedly connected to the guiding sleeve 2, and one end of the other transmission mechanism 5 is fixedly connected to the support shaft 74.

[0087] The conveyor belt is cross-sleeved on the driving wheel 71 and the driven wheel 72 so that the driving wheel 71 and the driven wheel 72 rotate away from or towards each other. The guiding sleeve 2 drives the two locking members 4 to move synchronously between the locking position and the unlocking position through the driving mechanism 7.

[0088] It should be noted that the conveyor belt is cross-sleeved on the driving wheel 71 and the driven wheel 72, that is, the part of the conveyor belt sleeved on the top of the driving wheel 71 extends to the bottom of the driven wheel 72 and is sleeved on the driven wheel 72 from the bottom to the top of the driven wheel 72. Similarly, the part of the conveyor belt sleeved on the bottom of the driving wheel 71 extends to the top of the driven wheel 72 and is sleeved on the driven wheel 72 from the top to the bottom of the driven wheel 72. In this way, the conveyor belt forms a spatial cross between the driving wheel 71 and the driven wheel 72.

[0089] It can be understood that the cross conveyor belt is prone to friction between the belts at the crossing position, which affects the working stability of the driving mechanism 7. Specifically, it can be alleviated by adjusting the driving wheel 71 and the driven wheel 72 or the inclination direction of the annular groove on the driving wheel 71 and the driven wheel 72 that defines the rotation direction of the conveyor belt, or by setting a limiting member 75 at the crossing position of the conveyor belt to separate the conveyor belts at the crossing position.

[0090] In this embodiment, the locking structure further includes: a limiting member 75. The limiting member 75 is located between the driving wheel 71 and the driven wheel 72, and the crossing positions of the conveyor belt are respectively located on opposite sides of the limiting member 75. Among them, the limiting member 75 can be fixedly connected or rotatably connected to the support frame 1.

In this embodiment, by setting the cross-sectional shape of the conveyor belt, setting the limiting member 75, and defining the connection method between the limiting member 75 and the support frame 1, the friction received by the conveyor belt at the crossing position is effectively reduced, not only improving the stability of the driving mechanism 7, but also extending the service life of the conveyor belt.

[0092] It should be noted that in combination with Figure 6 and Figure 7, a support plate 65 is fixedly arranged inside the support frame 1, and a second connection hole 651 and a third connection hole 652 are formed on the support plate 65.

The driving rod 3 is connected to the button 811, the button 811 is movably connected to the elastic driving component 9 along a second direction, and the elastic driving component 9 is connected to the support frame 1.

[0094] The button 811 can move relative to the elastic driving component 9 between a first pressing position and a second pressing position, so as to drive the guide sleeve 2 to swing between a first extreme position and a second extreme position through the driving rod 3. The elastic driving component 9 is used to limit the button 811 when the button 811 moves to the first pressing position or the second pressing position.

[0095] In this embodiment, a circular groove 812 is formed on the button 811, and the front end of the driving rod 3 is fixedly connected to the button 811 through the circular groove 812. The elastic driving component 9 includes: a driving frame 91, a movable rod 92, a sliding member 93 and an elastic member 94. Among them, the button 811 extends in the left - right direction and forms a handle 81, and the handle 81 is slidably connected to the driving frame 91 along the front - rear direction through a notch of the driving frame 91, so as to limit the handle 81; the elastic member 94 is placed between the driving frame 91 and the sliding member 93 to provide a driving force for the sliding member 93. One end of the movable rod 92 is pivotally connected to the driving frame 91, and the other end of the movable rod 92 with a frustum is located in the sliding member 93 and is slidably connected to the sliding member 93, and the handle 81 is fixedly connected to the corresponding sliding member 93 respectively.

[0096] Specifically, combined with Figure 10 and Figure 11The driving frame 91 is provided with a sliding cavity 911 extending along the second direction, and the sliding cavity 911 is connected with the notch. The sliding member 93, the movable rod 92 and the elastic member 94 are all located in the sliding cavity 911. The surface of the sliding member 93 is provided with a rotation clamping groove 931. The rotation clamping groove 931 includes: a first clamping point 9311, a second clamping point 9312, a first turning point 9313 and a second turning point 9314. The first clamping point 9311 is located on the side of the second clamping point 9312 facing forward; the first turning point 9313 and the second turning point 9314 are respectively located on opposite sides of the straight line where the first clamping point 9311 and the second clamping point 9312 are located. In this embodiment, the first turning point 9313 is located on the upper side of the straight line where the first card point 9311 and the second card point 9312 are located, and the second turning point 9314 is located on the lower side of the straight line where the first card point 9311 and the second card point 9312 are located. The first turning point 9313 and the second turning point 9314 are both located in front of the first card point 9311.

[0097] Combination Figure 8 and Figure 9 The movable rod 92 includes a pivot end and a plug end. The movable rod 92 is used to stop the elastic member 94 from driving the sliding member 93 to move forward when the plug end is located at the first locking position 9311 or the second locking position 9312. The rotation locking groove 931 can be provided in the sliding member 93 or on the surface of the sliding member 93.

[0098] In this embodiment, the sliding member 93 is a sliding block; the rotational positioning groove 931 is provided on the surface of the sliding member 93, and the shape of the rotational positioning groove 931 is similar to a heart shape; a truncated cone-shaped guide column is fixedly provided at the front end of the plug-in end, and the plug-in end is slidably plugged with the sliding member 93 through the guide column and the rotational positioning groove 931; the pivoting end is pivoted with the driving frame 91 along the left and right directions; the elastic member 94 is a compression spring, which is used to apply a forward force to the sliding member 93. Among them, the first positioning point 9311, the second positioning point 9312, the first turning point 9313 and the second turning point 9314 are all used to describe the position of the plug-in end relative to the rotational positioning groove 931. By setting a truncated cone-shaped guide column, it is possible to ensure that the guide column slides stably in the rotational positioning groove 931, and prevent the guide column from being separated from the rotational positioning groove 931.

[0099] In the process of moving the plug-in end from the first card position 9311 to the second card position 9312, the plug-in end moves to the second card position 9312 via the first turning point 9313; in the process of moving the plug-in end from the second card position 9312 to the first card position 9311, the plug-in end moves to the first card position 9311 via the second turning point 9314.

[0100] In this embodiment, the number of elastic drive components 9 is two, and they are respectively located on the left and right sides of the button 811; the openings of the sliding cavities 911 are arranged oppositely. When the plug-in end moves to the first card position 9311, the button 811 is at the first pressing station; when the plug-in end moves to the second card position 9312, the button 811 is at the second pressing station.

[0101] The locking structure provided by this embodiment is simple to operate, and the locking and unlocking of the support frame 1 and external devices can be realized without additional tools. Moreover, the structure is compact and the space utilization rate is high, which is particularly suitable for long strip-shaped installation spaces.

[0102] In a second aspect, an embodiment of the present invention provides a drawing device, in combination with Figure 12 , the drawing device includes: a frame 100, a bracket and a locking structure according to any one of the first aspect.

[0103] Among them, in combination with Figure 13 and Figure 14 , a drawing port 101 is provided on the surface of the frame 100, and the support frame 1 is slidably connected to the frame 100 along the second direction through the drawing port 101, and the support frame 1 is fixedly connected to the bracket.

[0104] An insertion hole 103 is further provided on the frame 100. When the guide sleeve 2 is at the first extreme position, the locking member 4 is inserted into the support frame 1 through the insertion hole 103.

[0105] In this embodiment, the frame 100 is of a box structure, and the number of drawing ports 101 is eight and they are all opened on the front panel of the frame 100. Among them, two through-hole riveting posts 102 arranged in the left-right direction are correspondingly installed in each drawing port 101, and the insertion hole 103 is the through hole on the through-hole riveting post 102. When the locking member is at the locking station, the upper end of the locking member extends out of the support frame 1 and is inserted into the external frame 100, thereby blocking the front-back movement of the support frame 1 on the frame 100, and further realizing the fixation of the support frame 1 relative to the frame 100. When the locking member is at the unlocking station, the upper end of the locking member does not extend out of the support frame 1, so that the locking member is separated from the external frame 100, and the support frame 1 can move relative to the frame 100 in the front-back direction, thereby realizing the drawing of the support frame 1 relative to the frame 100.

[0106] Further, in combination with Figure 4 and Figure 15 , the support frame 1 is fixedly connected with a module housing 110. Among them, the module housing 110 is used to load electronic devices; the button 811 is exposed outside the module housing 110. In this embodiment, the module housing 110 loads a PCIE board and forms a PCIE module.

[0107] Specifically, the PCB board is fixed to the bottom of the module housing 110 with a pan head combination screw. In the locked state, the handle 81 is flush with the module housing 110 and does not occupy extra space in the rack 100. The front panel of the module housing 110 is perforated to ensure heat dissipation and at the same time expose the interfaces, which can be customized according to customer needs and are not specifically limited in this embodiment. Combined with Figure 15 , the drive frame 91 is placed on the module housing 110 and locked with the first fixing hole 125 through two M3X4 screws via the third screw hole 123; the first screw hole 121 and the second screw hole 122 of the support frame 1 are fixed to the fourth screw hole 124 on the module housing 110 and the second fixing hole 126 on the drive frame 91 respectively through four M3X4 screws.

[0108] When it is necessary to take out the PCIE module for maintenance, just press the handle 81 backward, so that the sliding member 93 overcomes the elastic force of the elastic member 94, and the driving rod 3 moves from the first card position 9311 to the second card position 9312 under the action of the elastic force of the elastic member 94. At this time, the handle 81 is ejected outward, and the ejection distance can be controlled according to the size of the rotary card slot 931. When the handle 81 moves forward during the outward ejection movement, the driving rod 3 is driven to move forward. When the guiding boss 61 moves forward along the spiral chute 62, the guiding sleeve 2 will rotate 180 degrees clockwise, and then drive the driving wheel 71 to move clockwise in the direction of the horizontal arrow as shown in Figure 16 . The driven wheel 72 moves in the opposite direction to the driving wheel 71, which is counterclockwise. At this time, the guiding sleeve 2 drives the driving wheel 71 and the first connecting rod 511 to rotate. The driving wheel 71 drives the driven wheel 72 and the support shaft 74 to rotate through the conveyor belt 73.

[0109] The guiding sleeve 2 drives the first connecting rod 511 on the left side to rotate 180 degrees clockwise from the Figure 16 position and the support shaft 74 drives the first connecting rod 511 on the right side to rotate 180 degrees counterclockwise from the Figure 16 position. During this process, the second connecting rod 512 drives the slider 52 to slide along the horizontal part 121 of the support frame 1. During the movement of the slider 52, a driving force will be given to the stroke shaft 63, so that the stroke shaft 63 moves along the inclined groove 521 of the slider 52. At the same time, the inclined groove 521 and the L-shaped chute 12 cooperate with each other, and the stroke shaft 63 drives the locking member 4 to move vertically downward from the top in the L-shaped chute 12 to disengage from the through-hole rivet post 102. Then the two stroke shafts 63 move horizontally left and right. During the horizontal left and right movement of the two stroke shafts 63, the locking member 4 moves on the perforation 11 of the support frame 1 and will not disengage. When the movable rod 92 moves to the second card position 9312 along the rotary card slot 931 on the sliding member 93 under the elastic force of the elastic member 94, the unlocking of the PCIE module is realized. In this way, just pull the handle 81 forward, and the PCIE module can be taken out from the rack 100.

[0110] When the PCIE module needs to be fixed on the rack 100, after inserting the PCIE module into the chassis, press the handle 81, so that the sliding member 93 overcomes the elastic force of the elastic member 94, and the driving rod 3 moves along the rotary clamping groove 931 on the sliding member 93 to the first clamping point 9311. During the backward movement of the handle 81, the driving rod 3 is driven to move backward. When the guiding boss 61 moves backward along the spiral chute 62, the guiding sleeve 2 will rotate 180°, and then drive the driving wheel 71 to move counterclockwise in the direction of the arrow as shown in Figure 17 . The driven wheel 72 moves in the opposite direction to the driving wheel 71, which is clockwise rotation. At this time, the guiding sleeve 2 drives the driving wheel 71 and the connected first connecting rod 511 to rotate. The driving wheel 71 drives the driven wheel 72 and the support shaft 74 to rotate through the conveyor belt 73, and the support shaft 74 drives the connected first connecting rod 511 to rotate.

[0111] The guiding sleeve 2 drives the first connecting rod 511 to rotate counterclockwise by 180 degrees from the position of Figure 17 and the support shaft 74 drives the first connecting rod 511 to rotate clockwise by 180 degrees from the position of Figure 17 . During this process, the second connecting rod 512 drives the slider 52 to slide in the corresponding chute on the support frame 1. During the movement of the slider 52, a driving force will be given to the stroke shaft 63, so that the stroke shaft 63 moves along the inclined chute 521 of the slider 52. At the same time, the inclined chute 521 and the L-shaped chute 12 cooperate with each other, and the stroke shaft 63 drives the locking member 4 to move left and right in the L-shaped chute 12, and then move upward at the vertical part of the L-shaped chute 12 and insert into Figure 14 the through hole riveting post 102. When the driving rod 3 moves along the rotary clamping groove 931 to the first clamping point 9311 under the elastic force of the spring, the elastic force of the elastic member 94 always acts on the driving rod 3, and the handle 81 is hidden in the rack 100 and is flush with the front panel of the rack 100, thereby reducing the overall size of the whole machine and realizing the locking of the PCIE module.

[0112] The pulling device provided in this embodiment has a simple structure and high space utilization rate. It can realize the disassembly and assembly of the PCIE module without tools, and at the same time has excellent ergonomics, which can fully improve the user experience. At the same time, it can also reduce the overall size of the chassis and improve the market competitiveness of the product.
