The positioning component 104 can move in a first direction (i.e., vertical direction) relative to the shell 102. The positioning body 152 is accommodated in the shell cavity 112. The adjusting member 106 has an adjusting member axis X and can rotate around the adjusting member axis X relative to the shell 102. The limiting member 107 is connected to the adjusting member 106 to prevent the adjusting member 106 from moving along the adjusting member axis X relative to the shell 102. In an embodiment of the present application, the limiting member 107 is a limiting ring. The motion conversion component 130 is configured to cause the rotation of the adjusting member 106 around the adjusting member axis X to drive the positioning component 104 to move in a first direction relative to the shell 102. Among them, the adjusting member axis X is substantially perpendicular to the first direction. The adjusting member axis X extends along the left-right direction.

[0049] It should be noted that in order to ensure that the directions of the various figures are consistent, this application uses Figure 1B That is, the left-right direction is defined by the extension direction of the adjustment member axis X, the up-down direction is defined by the extension direction of the first direction (vertical direction), and the second direction is defined by the direction substantially perpendicular to the adjustment member axis X and the first direction.

[0050] In addition, the fixing assembly further includes a limiting structure 141, a positioning structure 143 and a display structure 146. The limiting structure 141 is disposed on the adjusting member 106 and the housing 102, and is configured to limit the maximum angle of rotation of the adjusting member 106 around the adjusting member axis X. The positioning structure 143 is disposed on the adjusting member 106 and the housing 102, and is configured to hinder the relative movement of the adjusting member 106 and the housing 102. The display structure 146 is disposed on the adjusting member 106 and the housing 102, and is configured to display the distance that the positioning component 104 moves relative to the housing 102 along the first direction.

[0051] like Figure 1B-1C As shown, the motion conversion component 130 includes a slider 108, a first motion conversion structure 131 and a second motion conversion structure 132. A positioning body accommodating portion 116 is provided in the positioning component 104. The slider 108 is accommodated in the positioning body accommodating portion 116 and can move along the adjusting member axis X. The first motion conversion structure 131 is arranged on the adjusting member 106 and the slider 108, and is configured to convert the rotation of the adjusting member 106 around the adjusting member axis X into the movement of the slider 108 around the adjusting member axis X. Among them, the first motion conversion structure 131 is a threaded structure, which includes an internal thread 142 arranged on the slider 108 and an external thread 144 arranged on the adjusting member 106. The second motion conversion structure 132 is arranged on the slider 108 and the positioning component 104, and is configured to convert the movement of the slider 108 around the adjusting member axis X into the movement of the positioning component 104 along the first direction. Further, the second motion conversion structure 132 is configured such that the movement distance of the positioning body 152 along the first direction increases as the movement distance of the slider 108 along the adjusting member axis X increases. In the first embodiment of the second motion conversion structure 132, the second motion conversion structure 132 is configured such that the movement distance of the slider 108 along the adjusting member axis X is proportional to the movement distance of the positioning component 104 along the first direction. The second motion conversion structure 132 includes a slider inclined portion provided on the slider 108 and a positioning component inclined portion provided on the positioning component 104.

[0052] Figure 2 yes Figure 1C The three-dimensional view of the housing 102 is shown in FIG. Figure 2As shown, the shell 102 includes a shell body 202 and a side plate 204. The side plate 204 is arranged on the right side of the shell body 202 and is connected to the shell body 202. Specifically, the side plate 204 is extended in the front-to-back direction. The shell cavity 112 is extended downward from the upper surface of the shell body 202 to accommodate the positioning component 104 and the slider 108. The size of the shell cavity 112 in the left-right direction is larger than the size of the slider 108 in the left-right direction, so that the slider 108 can move in the left-right direction in the shell cavity 112. The hole 114 extends in the left-right direction and passes through the shell body 202 and the side plate 204, so that the adjustment member 106 can extend into the shell cavity 112 through the hole 114. Four shell positioning members 206 are also provided on the shell 102. The shell positioning member 206 is extended to the right from the right surface of the side plate 204 of the shell 102. The shell positioning member 206 is used to extend into the first member 1001 to be connected (see Fig. 10A In other words, the housing positioning member 206 can position the housing 102 relative to the first member 1001 to be connected along the axis X direction of the adjusting member.

[0053] like Figure 2 As shown, the limiting structure 141 includes a boss 212 disposed on the housing 102. The boss 212 extends rightward from the right surface of the side plate 204. The boss 212 forms a first abutment surface 222 (i.e., a front abutment surface) and a second abutment surface 224 (i.e., a rear abutment surface) that are oppositely disposed in the front-to-back direction. A boss accommodating portion 214 is provided on the boss 212. The boss accommodating portion 214 is formed by being recessed to the left from the right surface of the boss 212, and the cross section of the right surface of the boss 212 is formed into a V shape.

[0054] like Figure 2 As shown, the positioning structure 143 includes two grooves 232 disposed on the housing 102. The two grooves 232 are disposed above and below the hole 114, respectively, and are formed by being recessed to the left from the right surface of the side plate 204. The two grooves 232 extend along the radial direction of the hole 114.

[0055] It should be noted that, although the positioning structure 143 in the present application includes two grooves 232 , the positioning structure 143 including at least one groove 232 is within the protection scope of the present application.

[0056] like Figure 2As shown, the display structure 146 includes a display area 242 arranged on the housing 102. The display area 242 is located on the right surface of the side plate 204. The display area 242 is arranged along the circumference of the hole 114, and when the adjusting member 106 is installed in place on the housing 102, the adjusting member 106 will not block the display area 242. Several numerical values ​​244 are displayed on the display area 242. In the present application, several numerical values ​​244 include positive numbers, the number 0 and negative numbers. The number 0 is located below the hole 114 and is arranged relative to the boss 212. The display area 242 is also provided with arrows 252 and arrows 254 on both sides of 0, and the positive and negative directions represented by the arrows are shown. In the present application, starting from the number 0, the numerical value displayed in the counterclockwise direction around the adjusting member axis X is a negative number, and the absolute value of the negative number increases in the counterclockwise direction. Starting from the number 0, the values ​​displayed in the clockwise direction around the adjustment element axis X are positive numbers, and the positive values ​​increase in the clockwise direction.

[0057] Figure 3 Yes Figure 1C The three-dimensional view of the positioning component 104 is shown. Figure 3 As shown, the positioning pin 154 is arranged above the positioning body 152 and connected to the positioning body 152. The positioning pin 154 is formed to extend along the axis X of the adjustment member and is used to extend into the second member 1002 to be connected (see Fig. 10A In other words, the positioning pin 154 can position the positioning component 104 relative to the second component 1002 along the axis X direction of the adjusting component.

[0058] like Figure 3 As shown, the positioning body 152 is roughly a cube. A positioning body accommodating portion 116 is provided on the positioning body 152 for accommodating the slider 108. The positioning body accommodating portion 116 penetrates the positioning body 152 in the left-right direction, so that the slider 108 can move in the left-right direction relative to the positioning body 152. The positioning component inclined portion of the second motion conversion structure 132 includes a first positioning component inclined portion 312 and a second positioning component inclined portion 314. The first positioning component inclined portion 312 and the second positioning component inclined portion 314 are inclined surfaces, which respectively constitute the upper surface and the lower surface of the positioning body accommodating portion 116. The upper surface and the lower surface are located on opposite sides of the positioning body accommodating portion 116 along the first direction. The inclination angles of the two inclined surfaces are the same.

[0059] Figure 4 Yes Figure 1C The three-dimensional view of the slider 108 shown in FIG. Figure 4As shown, the slider 108 includes a first slider inclined portion 402 and a second slider inclined portion 404 that are arranged opposite to each other. The first slider inclined portion 402 and the second slider inclined portion 404 are located on opposite sides of the slider 108 along the first direction. The first slider inclined portion 402 and the second slider inclined portion 404 are inclined surfaces, and the inclination angles of the first slider inclined portion 402 and the second slider inclined portion 404 are the same as the inclination angles of the first positioning component inclined portion 312 and the second positioning component inclined portion 314. In other words, on the cross section formed by the first direction and the adjusting member axis X, the slope of the inclined surface is a constant that is not equal to 0 (that is, the slopes of the inclined surfaces are the same).

[0060] Thus, when the slider 108 is accommodated in the positioning body accommodating portion 116, the movement of the slider 108 along the adjusting member axis X can be transmitted to the first positioning member inclined portion 312 and the second positioning member inclined portion 314 through the first slider inclined portion 402 and the second slider inclined portion 404, thereby driving the positioning body 152 to move along the first direction. The movement distance of the slider 108 along the adjusting member axis X is proportional to the movement distance of the positioning body 152 along the first direction. For example, for every 1 mm movement of the slider 108 along the adjusting member axis X, the positioning body 152 moves 0.2 cm along the first direction.

[0061] like Figure 4 As shown, the slider 108 is further provided with an adjusting member hole 406 . The adjusting member hole 406 penetrates the slider 108 along the adjusting member axis X. An internal thread 142 is provided on the inner wall of the adjusting member hole 406 for matching with the external thread 144 on the adjusting member 106 .

[0062] Figure 5A-5B Yes Figure 1C The three-dimensional images of the adjusting member 106 in different directions are shown. Figure 5A-5B As shown, the adjusting member 106 includes an adjusting member head 502 and an adjusting member tail 503. The adjusting member head 502 is roughly disc-shaped. An operating portion 510 is provided on the adjusting member head 502. The operating portion 510 is used to cooperate with a tool (not shown, for example, a screwdriver) so that the tool can rotate the adjusting member 106 by rotating the operating portion 510. Specifically, the operating portion 510 includes an operating protrusion 512. The operating protrusion 512 extends to the right from the right surface of the adjusting member head 502. A recess 514 is provided on the operating protrusion 512. The shape of the inner wall of the recess 514 matches the shape of the tool. The adjusting member tail 503 is located on the left side of the adjusting member head 502 and is connected to the adjusting member head 502. The adjusting member tail 503 is roughly cylindrical. External threads 144 are arranged on the outer surface of the adjusting member tail 503. In addition, a limiting recess 522 is provided on the end of the adjusting member tail 503 away from the adjusting member head 502 for accommodating the limiting member 107 (see Figure 1B-1CSpecifically, the limiting member 107 is annular and can be accommodated in the limiting recess 522. The limiting member 107 is used to prevent the adjusting member 106 from moving rightward along the adjusting member axis X.

[0063] like Figure 5A As shown, the limiting structure 141 also includes a protrusion 504 arranged on the adjusting member head 502. The protrusion 504 is formed to protrude outward from the adjusting member head 502 along the radial direction of the adjusting member head 502. The protrusion 504 can be accommodated in the boss accommodating portion 214 of the housing 102. The protrusion 504 can also leave the boss accommodating portion 214 and rotate between the first abutting surface 222 and the second abutting surface 224 around the adjusting member axis X. Specifically, after the protrusion 504 leaves the boss accommodating portion 214, the first abutting surface 222 and the second abutting surface 224 can abut against the protrusion 504, thereby preventing the protrusion 504 from rotating.

[0064] like Figure 5A As shown, the display structure 146 also includes a pointer 506 disposed on the adjusting member head 502. The pointer 506 is disposed on the right surface of the adjusting member head 502. It is disposed along the radial direction of the adjusting member head 502. When the adjusting member 106 is assembled in place on the housing 102, the pointer 506 will point to the display area 242 on the housing 102, and point to a certain value in the display area 242. The value pointed to by the pointer 506 represents the distance that the positioning component 104 moves relative to the housing 102 along the first direction.

[0065] like Figure 5B As shown, the positioning structure 143 also includes a plurality of protruding ridges 507 disposed on the adjusting member head 502. The plurality of protruding ridges 507 extend from the left surface of the adjusting member head 502 to the left and away from the adjusting member head 502. The plurality of protruding ridges 507 are arranged in the circumferential direction around the adjusting member head 502, and when the adjusting member 106 is assembled in place on the housing 102, two of the plurality of protruding ridges 507 can be respectively accommodated in the grooves 232 on the housing 102 (see Figure 2 ).

[0066] Figure 6 1 is a cross-sectional view of the fixing assembly, thereby showing the specific shapes of the cross-section (ie, cross section) of the internal thread 142 on the slider 108 and the external thread 144 provided on the adjusting member 106. Figure 6As shown, each of the internal thread 142 and the external thread 144 has a first thread 602 and a second thread 604 with different cross-sectional shapes. In other words, the tooth profiles of the first thread 602 and the second thread 604 are different. The first thread 602 and the second thread 604 are alternately arranged in the direction along the axis X of the adjusting member. Specifically, in the embodiment of the present application, the first thread 602 and the second thread 604 are both sawtooth-shaped. The tooth side angle φ1 on the left side of the first thread 602 is 24°, and the tooth side angle φ2 on the right side of the first thread 602 is 36°. The tooth side angle φ1 on the left side of the second thread 604 is 36°, and the tooth side angle φ2 on the right side of the second thread 604 is 24°.

[0067] It should be noted that although the tooth angles of the first thread 602 and the second thread 604 in the present application (i.e., the sum of the tooth side angle on the left and the tooth side angle on the right) are the same, in other embodiments, the tooth angles of the first thread 602 and the second thread 604 may also be different.

[0068] It should also be noted that, although the tooth profiles of the first thread 602 and the second thread 604 are different in the present application, in other embodiments, the tooth profiles of the first thread 602 and the second thread 604 may also be the same.

[0069] The adjusting member 106 of the present application has an initial position, a first extreme position and a second extreme position. When the fixing assembly is assembled in place, the adjusting member 106 is in the initial position. The adjusting member 106 can rotate around the adjusting member axis X from the initial position to the first extreme position or from the initial position to the second extreme position.

[0070] Fig. 7A is a front view of a first embodiment of a fixing assembly, Figure 7B is a cross-sectional view of a first embodiment of a fixing assembly, Figure 7C FIG. 1 is a top view of a first embodiment of a fixing assembly. Figures 7A-7C As shown, when the fixing assembly is assembled in place, the adjusting member 106 is in the initial position. The following describes an exemplary process of the operator assembling the fixing assembly in place:

[0071] The operator can first insert the slider 108 into the positioning body receiving portion 116 of the positioning component 104, so that the first slider inclined portion 402 abuts against the first positioning component inclined portion 312, and the second slider inclined portion 404 abuts against the second positioning component inclined portion 314. Then the operator inserts the slider 108 and the positioning component 104 together into the housing cavity 112 of the housing 102, and aligns the adjustment member hole 406 on the slider 108 with the hole 114 on the housing 102. Next, the operator inserts the adjustment member 106 into the hole 114 and the adjustment member hole 406 of the housing 102, and twists the adjustment member 106 until the pointer 506 is aligned with the number 0 in the display area 242, and the protrusion 504 of the adjustment member 106 is accommodated in the boss receiving portion 214 of the housing 102. The operator sets the limiter 107 on the adjustment member tail 503 of the adjustment member 106, and accommodates the limiter 107 in the limiter recess 522. Thus, the left side of the adjusting member tail 503 is limited by the limiting member 107, and the right side is limited by the adjusting member head 502, so as to be kept in place. Thus, the fixing assembly is assembled in place, and the adjusting member 106 is in the initial position.

[0072] Fig. 8A is a perspective view of a first embodiment of a fixing assembly, Figure 8B FIG. 1 is a cross-sectional view of a first embodiment of a fixing assembly, wherein the adjusting member 106 is in a first extreme position. Figures 8A-8B As shown, when the adjusting member 106 is located at the first limit position, the protrusion 504 of the adjusting member 106 abuts against the second abutting surface 224 of the protrusion 504. The pointer 506 of the adjusting member 106 points to the number -3 in the display area 242 on the housing 102.

[0073] refer to Figures 7A-8B When the adjusting member 106 moves from the initial position to the first limit position, the adjusting member 106 rotates counterclockwise around the adjusting member axis X. When the adjusting member 106 rotates counterclockwise around the adjusting member axis X, the adjusting member 106 is slightly deformed, and the protrusion 504 accommodated in the boss accommodating portion 214 passes over the first abutting surface 222 and leaves the boss accommodating portion 214 under the guidance of the wall surface of the boss accommodating portion 214.

[0074] like Figures 8A-8B As shown, during the movement of the adjusting member 106 from the initial position to the first extreme position, the rotation of the adjusting member 106 around the adjusting member axis X drives the slider 108 to move rightward along the adjusting member axis X through the threaded structure, so that the positioning member 104 moves downward along the first direction under the cooperation of the slider inclined portion and the positioning member inclined portion. When the adjusting member 106 is at the first extreme position, the pointer 506 of the adjusting member 106 points to the number -3 in the display area 242, which represents that the positioning member 104 moves downward along the first direction by 3 mm.

[0075] It should be noted that when the adjusting member 106 is located at the first limit position, the protrusion 504 of the adjusting member 106 abuts against the second abutment surface 224 of the protrusion 504. The second abutment surface 224 blocks the adjusting member 106 from continuing to rotate around the adjusting member axis X in the counterclockwise direction.

[0076] Fig. 9A is a perspective view of a first embodiment of a fixing assembly, Fig. 9B FIG. 1 is a cross-sectional view of the first embodiment of the fixing assembly, wherein the adjusting member 106 is in the second extreme position. Figures 9A-9B As shown, when the adjusting member 106 is located at the second extreme position, the protrusion 504 of the adjusting member 106 abuts against the first abutting surface 222 of the protrusion 504. The pointer 506 of the adjusting member 106 points to the number +3 in the display area 242 on the housing 102.

[0077] refer to Figures 7A-7C and Figures 9A-9B When the adjusting member 106 moves from the initial position to the second limit position, the adjusting member 106 rotates in the clockwise direction around the adjusting member axis X. When the adjusting member 106 rotates in the clockwise direction around the adjusting member axis X, the adjusting member 106 is slightly deformed, and the protrusion 504 accommodated in the boss accommodating portion 214 passes over the second abutting surface 224 and leaves the boss accommodating portion 214 under the guidance of the wall surface of the boss accommodating portion 214.

[0078] like Figures 9A-9B As shown, during the movement of the adjusting member 106 from the initial position to the second extreme position, the rotation of the adjusting member 106 around the adjusting member axis X drives the slider 109 to move leftward along the adjusting member axis X through the threaded structure, so that the positioning member 104 moves upward along the first direction under the cooperation of the slider inclined portion and the positioning member inclined portion. When the adjusting member 106 is at the second extreme position, the pointer 506 of the adjusting member 106 points to the number +3 in the display area 242, which represents that the positioning member 104 moves upward along the first direction by 3 mm.

[0079] It should be noted that when the adjusting member 106 is located at the second limit position, the protrusion 504 of the adjusting member 106 abuts against the first abutment surface 222 of the protrusion 504. The first abutment surface 222 blocks the adjusting member 106 from continuing to rotate around the adjusting member axis X in the clockwise direction.

[0080] In the present application, since the first motion conversion structure 131 is a threaded structure, the inclined portion of the slider and the inclined portion of the positioning component are inclined planes. Therefore, when the adjusting member 106 rotates around the adjusting member axis X, the angle of rotation of the adjusting member 106 around the adjusting member axis X is proportional to the distance the slider 108 moves along the adjusting member axis X and the distance the positioning component 104 moves along the first direction.

[0081] Thus, by rotating the adjusting member 106 around the adjusting member axis X, the positioning component 104 can be moved along the first direction relative to the housing 102 .

[0082] Figures 10A-10B 1 is a process diagram of connecting the first piece 1001 and the second piece 1002 according to the first embodiment of the fixing assembly of the present application. The first piece 1001 is provided with a first hole (not shown) for accommodating the shell positioning member 206 of the shell 102. The fixing assembly is connected to the first piece 1001 through the shell positioning member 206 of the shell 102. The second piece 1002 is provided with a second hole 1004 for accommodating the positioning pin 154. The fixing assembly is connected to the second piece 1002 through the positioning pin 154. After the first piece 1001 and the second piece 1002 are connected in place through the fixing assembly, the top surface 1011 of the first piece 1001 is flush with the top surface 1012 of the second piece 1002.

[0083] Reference below Figures 10A-10B The following is an exemplary process of connecting the first piece 1001 and the second piece 1002 by the fixing assembly: Figures 10A-10B As shown, the operator inserts the housing positioning member 206 of the fixed assembly that has been assembled in place (i.e., the adjusting member 106 is in the initial position) into the first hole of the first member 1001, thereby connecting the housing 102 of the fixed assembly to the first member 1001. Subsequently, the operator inserts the positioning pin 154 of the fixed assembly that has been assembled in place into the second hole 1004 on the second member 1002, thereby connecting the positioning member 104 of the fixed assembly to the second member 1002. Fig. 10A It can be seen that when the housing positioning member 206 is inserted into the hole of the first member and the positioning pin 154 is inserted into the hole 1004 of the second member, the top surface 1011 of the first member 1001 and the top surface 1012 of the second member 1002 have a height difference D. At this time, the operator can rotate the adjustment member 106 clockwise around the axis X of the adjustment member, so that the positioning pin 154 moves upward in the first direction relative to the housing 102 until the top surface 1011 of the first member 1001 is flush with the top surface 1012 of the second member 1002. When the top surface 1011 of the first member 1001 is flush with the top surface 1012 of the second member 1002, the operator can release the adjustment member 106. The several protruding edges 507 (see Figure 5B ) are respectively received in the grooves 232 on the housing 102 (see Figure 2 ), so that the adjusting member 106 remains in place relative to the housing 102. In addition, the operator can observe the specific number in the display area 242 pointed to by the pointer 506, so as to know the distance that the adjusting member 106 moves relative to the housing 102.

[0084] Therefore, the fixing assembly of the present application can connect the first piece 1001 and the second piece 1002 when the setting positions of the holes 1004 of the first piece deviate from the predetermined positions, and make the connected first piece 1001 and the second piece 1002 be located at a preset position (for example, the top surface 1011 of the first piece 1001 is flush with the top surface 1012 of the second piece 1002).

[0085] It should be noted that although the motion conversion component 130 in the present application includes a slider 108, a first motion conversion structure 131 and a second motion conversion structure 132, in other embodiments, any motion conversion component configured so that the rotation of the adjustment member 106 around the axis of the adjustment member drives the positioning body 152 to move along the first direction relative to the shell 102 is within the protection scope of the present application.

[0086] It should also be noted that although the first motion conversion structure 131 in the present application is a threaded structure, in other embodiments, any first motion conversion structure configured to convert the rotation of the adjusting member 106 around the adjusting member axis X into the movement of the slider 108 around the adjusting member axis X is within the protection scope of the present application.

[0087] It should also be noted that, although the slider inclined portion provided on the slider 108 and the positioning component inclined portion provided on the positioning component 104 in the present application are both inclined planes, and the left end of the inclined portion is lower than the right end of the inclined portion, in other embodiments, the inclined portion may also be other shapes (for example, an inclined curved surface), or the left end of the inclined portion may be higher than the right end of the inclined portion.

[0088] In addition, although the second motion conversion structure 132 in the present application includes a slider inclined portion arranged on the slider 108 and a positioning component inclined portion arranged on the positioning component 104, in other embodiments, any second motion conversion structure configured to convert the movement of the slider 108 along the axis X around the adjusting member into the movement of the positioning component 104 along the first direction is within the scope of protection of the present application.

[0089] Fig.11 is a perspective view of the second embodiment of the fixing assembly of the present application. Fig.11 The second embodiment of the fixing assembly shown is Figure 1A-9B The similarities of the first embodiment of the fixing assembly shown are not repeated here, and the main differences are that the shell locating member 206 is separately arranged from the shell 102, and the shell locating member 206 and the locating pin 154 are configured to respectively connect a first member and a second member (not shown) to be connected, wherein the first member and the second member are located on opposite sides of the fixing assembly along a second direction substantially perpendicular to the axis X of the adjusting member and the first direction.

[0090] Specifically, if Fig.11As shown, the side plate 204 is formed by extending from the housing body 202 along the adjustment member axis X. The side plate 204 is provided with a hole 1102, and the hole 1102 penetrates the side plate 204 along the second direction, and is used to accommodate a housing positioning member 206. The housing positioning member 206 can extend into the hole 1102, and is used to extend into a hole (not shown) on the first member to be connected, so as to position the housing 102 relative to the first member. In other words, the housing positioning member 206 can position the housing 102 relative to the first member along the second direction. As an example, the housing positioning member 206 is a positioning column.

[0091] like Fig.11 As shown, the positioning pin 154 is connected to the positioning body 152 and extends along the second direction. The positioning pin 154 is used to extend into a second hole (not shown) of the second member to be connected, so as to position the positioning pin 154 relative to the second member. In other words, the positioning pin 154 can position the positioning member 104 relative to the second member 1002 along the second direction.

[0092] Therefore, the second embodiment of the fixing assembly of the present application can connect the first piece and the second piece located on both sides thereof in the second direction.

[0093] Fig.12 is a three-dimensional diagram of the third embodiment of the fixing assembly of the present application. Fig.12 The third embodiment of the fixing assembly shown is Figure 1A-9B The similarities of the first embodiment of the fixing assembly shown are not repeated, and the main difference is that the fixing assembly further includes a connecting member 1202. The connecting member 1202 is configured to penetrate the housing 102 and is configured to connect the housing 102, the first piece 1001 and the second piece 1002 together.

[0094] Specifically, if Fig.12 As shown, the housing 102 further includes an additional connecting plate 1204. The additional connecting plate 1204 is connected to the housing body 202 and extends downward from the housing body 202. The additional connecting plate 1204 is provided with an additional connecting hole 1210. The additional connecting hole 1210 penetrates the additional connecting plate 1204 along the axis X of the adjusting member. The first member 1001 is provided with a first member additional hole 1211. The second member 1002 is provided with a second member additional hole 1212. After the fixing assembly makes the top surface 1011 of the first member 1001 flush with the top surface 1012 of the second member 1002, the additional connecting hole 1210, the first member additional hole 1211 and the second member additional hole 1212 are aligned, and the connecting member 1202 passes through the additional connecting hole 1210, the first member additional hole 1211 and the second member additional hole 1212, thereby connecting the first member 1001, the second member 1002 and the housing 102 together.

[0095] Therefore, the third embodiment of the fixing assembly of the present application can further enhance the connection between the first piece 1001 , the second piece 1002 and the housing 102 .

[0096] Fig.13A 1 is an exploded view of the second embodiment of the second motion conversion structure 132 of the present application, the slider 108 and the positioning body 152. Fig. 13B yes Fig.13A The second embodiment of the second motion conversion structure 132, the slider 108 and the vertical cross-sectional view of the positioning body 152 are shown. Figures 13A-13B The second embodiment of the second motion conversion structure 132 shown in FIG. Figure 1A-9B The similarities with the first embodiment of the second motion conversion structure 132 shown are no longer repeated, and the main difference is that: in the first embodiment of the second motion conversion structure 132, the movement distance of the slider 108 along the axis X of the adjusting member is proportional to the movement distance of the positioning body 152 along the first direction, while in the second embodiment of the second motion conversion structure 132, the movement distance of the slider 108 along the axis X of the adjusting member is not proportional to the movement distance of the positioning body 152 along the first direction.

[0097] Specifically, Figures 13A-13B As shown, the second motion conversion structure 132 is arranged on the slider 108 and the positioning component 104. The second motion conversion structure 132 includes a slider matching portion arranged on the slider 108 and a protrusion arranged on the positioning component 104. The slider matching portion of the second motion conversion structure 132 includes a first slider matching portion 1306 and a second slider matching portion 1308. The first slider matching portion 1306 and the second slider matching portion 1308 are located on opposite sides of the slider 108 along the first direction. Each of the first slider matching portion 1306 and the second slider matching portion 1308 includes two first stage portions 1311 and a second stage portion 1312. In the direction of the axis X of the adjusting member, the second stage portion 1312 is located between the two first stage portions 1311 and is smoothly connected to the adjacent first stage portions 1311. The first stage portion 1311 is an inclined surface with a first slope, and the second stage portion 1312 is an inclined surface with a second slope different from the first slope. The first stage portion 1311 can increase the movement distance of the positioning body 152 along the first direction at a first speed as the movement distance of the slider 108 along the adjusting member axis X increases. The second stage portion 1312 can increase the movement distance of the positioning body 152 along the first direction at a second speed different from the first speed as the movement distance of the slider 108 along the adjusting member axis X increases. In other words, on the cross section formed by the first direction and the adjusting member axis X, the slopes of the outer contours of the first slider matching portion 1306 and the second slider matching portion 1308 vary.

[0098] like Figures 13A-13BAs shown, the protrusion of the second motion conversion structure 132 includes a first protrusion 1302 and a second protrusion 1304 provided on the slider 108. The first protrusion 1302 and the second protrusion 1304 are located on opposite sides of the positioning body receiving portion 116 along the first direction, and are formed by protruding from the inner wall of the positioning body receiving portion 116. The first protrusion 1302 is matched with the first slider matching portion 1306, and the second protrusion 1304 is matched with the second slider matching portion 1308.

[0099] Thus, when the slider 108 is accommodated in the positioning body accommodating portion 116, the movement of the slider 108 along the adjusting member axis X can be transmitted to the first protrusion 1302 and the second protrusion 1304 through the first slider matching portion 1306 and the second slider matching portion 1308, thereby driving the positioning body 152 to move along the first direction. The movement distance of the slider 108 along the adjusting member axis X is not proportional to the movement distance of the positioning body 152 along the first direction.

[0100] In this embodiment, the first speed is greater than the second speed, and the second speed is equal to 0. Since the second speed is equal to 0 (i.e., the second slope of the second stage portion 1312 is 0), when the protrusions on the positioning component 104 (i.e., the first protrusion 1302 and the second protrusion 1304) cooperate with the second stage portion 1312 on the slider 108, the movement of the positioning body 152 along the first direction does not increase with the movement of the slider 108 along the axis X of the adjusting member. In other words, in the entire cooperation movement of the protrusion on the positioning component 104 and the two first stage portions 1311 and the second stage portions 1312 on the slider 108, the distance moved by the positioning body 152 along the first direction does not increase with the movement distance of the slider 108 along the axis X of the adjusting member at each moment. However, this situation should also be considered to include the situation described in the present application where the movement distance of the positioning body 152 along the first direction increases as the movement distance of the slider 108 along the axis X of the adjusting member increases, because during the overall cooperation process between the positioning component 104 and the slider 108 (i.e., in the entire cooperation movement between the protrusion on the positioning component 104 and the two first stage portions 1311 and the second stage portions 1312 on the slider 108), there is still a trend that the movement distance of the positioning body 152 along the first direction increases as the movement distance of the slider 108 along the axis X of the adjusting member increases.

[0101] It should be noted that, although in the present embodiment, the second slope is 0, in other embodiments, the second slope may not be 0.

[0102] It should be noted that, although in the present application, each of the first slider mating portion 1306 and the second slider mating portion 1308 includes two first stage portions 1311 and second stage portions 1312, in other embodiments, each of the first slider mating portion 1306 and the second slider mating portion 1308 may include at least one first stage portion 1311 and at least one second stage portion 1312.

[0103] It should be noted that although the second motion conversion structure 132 in this embodiment includes a slider matching portion provided on the slider 108 and a protrusion provided on the positioning component 104, in other embodiments, it may also include a protrusion provided on the slider 108 and a matching portion provided on the positioning component 104.
