Description

Technical Field

[0001] This application relates to the field of satellite testing devices, and in particular to a satellite attitude conversion device. Background Art

[0002] When a satellite is in operation, it needs to adjust its attitude to maintain the stability of the satellite attitude axis. After the satellite is assembled, operators need to use a satellite attitude adjustment turntable to test the satellite attitude adjustment. Common attitude adjustment turntables include a base, several push rods, and a mounting plate. The satellite includes a flange, and through holes corresponding one by one to the holes on the flange are provided on the mounting plate.

[0003] During the test, the operator needs to align the holes on the flange with the corresponding through holes on the mounting plate, insert bolts into the holes on the flange and the through holes on the mounting plate at the same time, and then screw nuts onto the bolts. Through the cooperation of multiple bolts and nuts, the satellite is fixed on the mounting plate. After the satellite is fixed to the mounting plate, the satellite attitude adjustment turntable is started to conduct attitude conversion tests on the satellite.

[0004] When fixing the satellite to the mounting plate, it is necessary to separately turn multiple bolts and nuts, which takes a long time to fix the satellite, has an adverse effect on the efficiency of the satellite attitude conversion test, and the efficiency of the satellite attitude conversion test is low. Summary of the Invention

[0005] In order to improve the efficiency of the satellite attitude conversion test, this application provides a satellite attitude conversion device.

[0006] A satellite attitude conversion device provided by this application adopts the following technical solution:

[0007] A satellite attitude conversion device includes a base, multiple push rods installed on the base, and a mounting plate installed on the multiple push rods. The satellite is placed on the mounting plate. The satellite includes a flange. A plurality of mating holes are provided on the flange, and the plurality of mating holes are distributed along the circumferential direction of the flange. The diameter of the mating holes gradually decreases from bottom to top. Mounting grooves corresponding one by one to the mating holes are provided on the upper surface of the mounting plate. A support spring is fixedly connected to the bottom wall of the mounting groove. A bottom column is slidably inserted into the mounting groove. The support spring is fixedly connected to the bottom column. The diameter of the bottom column is larger than the maximum diameter of the mating holes. A support rod is fixedly connected to the upper end surface of the bottom column. The upper end of the support rod is fixedly connected to a mounting block. The diameters of the support rod and the mounting block are not larger than the minimum diameter of the mating holes. A plurality of grooves are provided on the side wall of the mounting block. A fixing spring is fixedly connected to the bottom wall of the groove. A fixing block is fixedly connected to the fixing spring. The fixing block is slidably inserted into the groove. When the fixing spring is in a natural state, the distance between the side wall of the fixing block away from the fixing spring and the axis of the mounting block is larger than the minimum diameter of the mating groove.

[0008] By adopting the above technical solution, when an operator needs to fix a satellite, first align the mating hole with the corresponding support rod, then deliver the satellite downward. The satellite drives the flange to move. When the fixing block moves to contact the hole wall of the mating hole, as the satellite and the flange continue to move downward, the hole wall of the mating hole pushes the fixing block into the groove, and the fixing spring is compressed while the fixing block moves. When the mating hole is completely located in the groove, the satellite and the flange continue to move downward. When the groove is located on the upper surface of the flange, the lower end surface of the flange contacts the upper end surface of the bottom column. The fixing spring resumes deformation and pushes the fixing block out of the groove. When the fixing spring resumes to its natural state, the lower surface of the fixing block contacts the upper end surface of the flange. The fixing block and the bottom column cooperate to fix the flange, thereby fixing the satellite to the mounting plate, reducing the situation where the operator needs to separately screw multiple bolts and nuts when fixing the satellite, reducing the time required to fix the satellite, and improving the efficiency of the satellite attitude conversion test.

[0009] Optionally, a reinforcement assembly for further fixing the flange is provided on the mounting plate.

[0010] By adopting the above technical solution, the reinforcement assembly cooperates with the bottom column and the fixing block to jointly fix the flange, enabling the satellite to be better fixed on the mounting plate.

[0011] Optionally, the reinforcement assembly includes cavities provided on the mounting plate and arranged corresponding to the bottom columns one by one. The cavities are located on the side of the bottom columns away from the axis of the mounting plate. A communication hole communicating with the cavity is provided on the upper surface of the mounting plate. A rotating shaft is rotatably connected in the communication hole. A rotating rod is fixedly connected to the rotating shaft. A torsion spring is connected to the rotating shaft. One end of the torsion spring is fixedly connected to the rotating rod, and the other end of the torsion spring is fixedly connected to one of the hole walls of the communication hole. One end of a connecting rod is fixedly connected to a pressing plate, and the other end of the connecting rod is fixedly connected to a mating plate. Both the pressing plate and the mating plate face the direction close to the bottom column. The end of the connecting rod connecting the pressing plate is located above the mounting plate and inclines away from the bottom column. The end of the connecting rod connecting the mating plate is located in the cavity and inclines towards the bottom column. A driving rod is fixedly connected to the side wall of the bottom column. The driving rod is simultaneously slidably inserted into the mounting groove and the cavity. The driving rod is located above the mating plate. A limiting member for fixing the rotating rod is also provided in the cavity.

[0012] By adopting the above technical solution, when the flange is located between the bottom column and the fixed block, the operator continues to press the satellite and the flange downward. The flange moves downward and presses the bottom column to move downward. The movement of the bottom column compresses the support spring. At the same time, the bottom column drives the driving rod to move downward. The movement of the driving rod presses the matching plate to move downward. The movement of the matching plate drives the rotating rod and the pressing plate to move toward the flange. When the rotating rod rotates, the torsion spring deforms. When the rotating rod is vertical, the pressing plate is located above the flange and the pressing plate is horizontal. At this time, the limiting member works to keep the rotating rod vertical. The operator stops pressing the satellite and the flange downward. The support spring restores deformation and pushes the flange and the satellite upward until the upper surface of the flange contacts the lower surface of the pressing plate. At this time, the support spring is in a compressed state. The flange abuts against the pressing plate. The pressing plate cooperates with the bottom column and the fixed block to fix the flange, so that the satellite is better fixed to the mounting plate.

[0013] Optionally, the limiting member includes a support plate arranged in the cavity. The support plate is located below the matching plate. A plurality of return springs are fixedly connected to the lower surface of the support plate. A matching groove is formed on the upper surface of the support plate. A magnetic plate is fixedly connected to each groove wall of the matching groove. A limiting groove corresponding to the matching groove is formed on the lower surface of the matching plate. A limiting spring is fixedly connected to the bottom wall of the limiting groove. A limiting block is fixedly connected to the limiting spring. The limiting block is slidably inserted into the limiting groove. The limiting block is adapted to the groove surrounded by the plurality of magnetic plates.

[0014] By adopting the above technical solution, when the driving rod presses the matching plate to move downward, the matching plate rotates and presses the support plate to move downward. When the support plate moves, the return spring is compressed. When the limiting block contacts the support plate, as the matching plate continues to rotate, the support plate pushes the limiting block into the fiber groove. The movement of the limiting block compresses the fiber spring. When the matching plate rotates until the limiting groove is aligned with the matching groove, the limiting spring restores deformation and pushes the limiting block into the matching groove. After the limiting block moves into the matching groove, the magnetic plate adsorbs and fixes the limiting block, so that the rotating rod is kept vertical and the pressing plate can fix the flange.

[0015] Optionally, a guide rod is inserted into the return spring. The upper end of the guide rod is fixedly connected to the lower surface of the support plate. The lower end of the guide rod penetrates the mounting plate and is slidably inserted into the mounting plate.

[0016] By adopting the above technical solution, the downward movement of the pallet drives the guide rod to move. After the operator stops pressing the satellite, the reset spring restores its deformation and pushes the bottom column, the driving rod, and the satellite upward, and the driving rod disengages from the mating plate; when the operator needs to remove the satellite from the mounting plate, first pull the guide rod downward. The movement of the guide rod drives the movement of the pallet. While the pallet moves, the reset spring is further compressed. The movement of the pallet causes the limiting block to gradually disengage from the mating groove. When the limiting block is outside the mating groove, the torsion spring restores its deformation and drives the rotating rod, the mating plate, and the pressing plate to rotate. The pressing plate rotates away from the bottom column. When the pressing plate disengages from the flange, the supporting spring restores its deformation and pushes the bottom column and the satellite upward. Finally, the operator pushes the fixing block into the groove and pulls the satellite upward until the mounting block disengages from the flange. At this time, the satellite can be removed from the mounting plate.

[0017] Optionally, a connecting rod is fixedly connected to the bottoms of several guide rods on the pallet, and the multiple connecting rods are fixedly connected to each other.

[0018] By adopting the above technical solution, when it is necessary to pull the guide rod downward, the operator pulls one of the connecting rods. The movement of the connecting rod drives the movement of the other connecting rods. While the connecting rods move, they drive the guide rod and the pallet to move downward, enabling the operator to more conveniently remove the satellite from the mounting plate.

[0019] Optionally, the rotating shaft penetrates through the rotating rod. A strip-shaped hole is opened at the position corresponding to the rotating shaft on the rotating rod. The torsion spring is sleeved on the rotating shaft. One end of the torsion spring is fixedly connected to the hole wall of the strip-shaped hole, and the other end of the torsion spring is fixedly connected to the hole wall of the communication hole close to the bottom column.

[0020] Optionally, a sliding hole communicating with the installation groove is opened on the cavity wall close to the bottom column. The length direction of the sliding hole is arranged along the thickness direction of the mounting plate, and the driving rod is inserted into the sliding hole.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] By setting the base, the push rod, the mounting plate, the bottom column, the supporting spring, the support rod, the mounting block, the fixing spring, and the fixing block, the time required for fixing the satellite is reduced, and the efficiency of the satellite attitude conversion test is improved;

[0023] By setting the rotating shaft, the rotating rod, the pressing plate, the mating plate, the driving rod, and the limiting member, the pressing plate cooperates with the bottom column and the fixing block to fix the flange, so that the satellite is better fixed to the mounting plate;

[0024] By setting the pallet, the reset spring, the limiting spring, and the limiting block, the magnetic plate adsorbs and fixes the limiting block, so that the rotating rod maintains a vertical state, and the pressing plate can fix the flange. Brief Description of the Drawings

Embodiment

[0032] The following further describes the present application in detail with reference to the Figures 1-6 drawings.

[0033] An embodiment of the present application discloses a satellite attitude conversion device. Referring to Figure 1 and Figure 2 , the satellite 4 attitude conversion device includes a base 1, a plurality of push rods 2 installed on the base 1, and a mounting plate 3. The push rods 2 are located between the base 1 and the mounting plate 3, and the mounting plate 3 is installed on the plurality of push rods 2. The satellite 4 includes a flange 41, and a plurality of mating holes 411 are formed in the flange 41. The mating holes 411 penetrate through the flange 41, and the plurality of mating holes 411 are distributed along the circumferential direction of the flange 41. The diameter of the mating holes 411 gradually decreases from bottom to top. The mounting plate 3 is provided with a fixing assembly 5 for fixing the satellite 4.

[0034] Reference Figure 3 With Figure 4 , the fixing component 5 includes mounting grooves 31 provided on the upper end surface of the mounting plate 3 corresponding one-to-one to the mating holes 411. The depth direction of the mounting grooves 31 is arranged along the thickness direction of the mounting plate 3. A support spring 51 is fixedly connected to the inner bottom wall of each mounting groove 31. The upper end of the support spring 51 is fixedly connected to a bottom post 52. The bottom post 52 is slidably inserted into the mounting groove 31. The upper end surface of the bottom post 52 is higher than the upper surface of the mounting plate 3. The diameter of the bottom post 52 is larger than the maximum diameter of the mating hole 411; a support rod 53 is perpendicularly fixedly connected to the upper end surface of the bottom post 52. The support rod 53 and the bottom post 52 are coaxially arranged. The diameter of the support rod 53 is smaller than the minimum diameter of the mating hole 411. The length of the support rod 53 is equal to the thickness of the flange 41.

[0035] An installation block 54 is fixedly connected to the upper end surface of the support rod 53. The diameter of the installation block 54 is smaller than the minimum diameter of the mating hole 411. In other embodiments, the diameter of the installation block 54 can also be equal to the minimum diameter of the mating hole 411; a plurality of grooves 541 are provided on the side wall of the installation block 54. The length direction of the grooves 541 is arranged along the radial direction of the installation block 54. The plurality of grooves 541 are distributed circumferentially along the installation block 54. A fixing spring 55 is fixedly connected to the bottom wall of the groove 541. The length direction of the fixing spring 55 is arranged along the radial direction of the installation block 54. A fixing block 56 is slidably inserted into the groove 541. The length of the groove 541 is greater than the length of the fixing block 56. The fixing block 56 is fixedly connected to the fixing spring 55; when the fixing spring 55 is in a natural state, one side of the fixing block 56 is inserted into the groove 541, and the other side of the fixing block 56 protrudes from the side wall of the installation block 54. At this time, the distance between the side wall of the fixing block 56 away from the fixing spring 55 and the axis of the installation block 54 is d1, d1 is greater than the minimum diameter of the mating hole 411, and d1 is less than the maximum diameter of the mating hole 411.

[0036] When fixing the satellite 4, the operator aligns the mating hole 411 on the flange 41 with the corresponding support rod 53, and then delivers the satellite 4 downward. When the fixing block 56 enters the mating hole 411 and contacts the hole wall of the mating hole 411, as the satellite 4 and the flange 41 continue to move downward, the hole wall of the mating hole 411 pushes the fixing block 56 to move into the groove 541, and the fixing block 56 compresses the fixing spring 55 while moving; when the fixing block 56 is completely located in the groove 541, as the satellite 4 and the flange 41 continue to move downward, when the groove 541 moves above the flange 41, the lower end surface of the flange 41 contacts the upper end surface of the bottom post 52, and at the same time the fixing spring 55 resumes deformation and pushes the fixing block 56 to move out of the groove 541 until the fixing spring 55 resumes to the natural state. At this time, one side of the fixing block 56 is outside the groove 541, and the lower surface of the fixing block 56 of the fixing block 56 contacts the upper end surface of the flange 41.

[0037] The flange 41 is located between the bottom column 52 and the fixing block 56. The fixing block 56 cooperates with the bottom column 52 to fix the flange 41, thereby fixing the satellite 4 to the mounting plate 3. This reduces the situation where operators need to separately turn multiple bolts and nuts when fixing the satellite 4, thus reducing the time required to fix the satellite 4 and improving the efficiency of the satellite 4 attitude conversion test. After starting the satellite 4 attitude conversion device, the push rod 2 pushes the mounting plate 3 to tilt in different directions, and the mounting plate 3 drives the satellite 4 to tilt and move, thereby completing the satellite 4 attitude conversion test.

[0038] To improve the fixing effect between the satellite 4 and the mounting plate 3, the mounting plate 3 is also provided with a reinforcement component 6 for further fixing the flange 41; the reinforcement component 6 includes cavities 32 opened on the mounting plate 3 corresponding one by one to the bottom columns 52. The cavities 32 are located on one side of the corresponding bottom columns 52. The bottom columns 52 and the corresponding cavities 32 are arranged in sequence along the direction away from the axis of the mounting plate 3. A communication hole 33 communicating with the cavity 32 is opened on the upper surface of the mounting plate 3. A rotating shaft 61 is provided in the communication hole 33. The length direction of the rotating shaft 61 is perpendicular to the axial direction of the bottom column 52. Both ends of the rotating shaft 61 are respectively rotatably connected to two opposite hole walls of the communication hole 33. When the flange 41 is fixed between the fixing block 56 and the bottom column 52, the rotating shaft 61 is located on one side of the side wall of the flange 41.

[0039] The reinforcement component 6 further includes a rotating rod 62. The rotating shaft 61 passes through the rotating rod 62 and is fixedly connected to the rotating rod 62. The rotating rod 62 is inserted into the communication hole 33. One end of the rotating rod 62 is located in the cavity 32, and the other end of the rotating rod 62 is located above the mounting plate 3; a mating plate 63 is fixedly connected to one end of the rotating rod 62 located in the cavity 32. The mating plate 63 is located on the side of the rotating rod 62 close to the bottom column 52. The rotating rod 62 and the mating plate 63 are perpendicular to each other. A sliding hole 34 corresponding to the driving rod 64 is opened on the cavity wall of the cavity 32 close to the mounting groove 31. The sliding hole 34 communicates the cavity 32 with the mounting groove 31. The length direction of the sliding hole 34 is arranged along the thickness direction of the mounting plate 3. A driving rod 64 corresponding to the mating plate 63 is vertically and fixedly connected to the bottom column 52. The driving rod 64 is slidably inserted into the sliding hole 34. The side of the driving rod 64 away from the bottom column 52 is located in the cavity 32.

[0040] A pressing plate 65 is fixedly connected to one end of the rotating rod 62 located above the mounting plate 3. The pressing plate 65 is perpendicular to the rotating rod 62. The pressing plate 65 is located on the side of the rotating rod 62 close to the bottom column 52; when the rotating rod 62 is in a vertical state, the distance between the lower surface of the pressing plate 65 and the upper surface of the mounting plate 3 is d2. When the support spring 51 is in a natural state, the distance between the lower surface of the fixing block 56 and the upper surface of the mounting plate 3 is d3, and d2 is less than d3.

[0041] A strip-shaped hole 621 penetrating through the rotating rod 62 is formed at the position where the rotating rod 62 penetrates through the rotating shaft 61, and the rotating shaft 61 is located in the strip-shaped hole 621; a torsion spring 66 is sleeved on the rotating shaft 61, one end of the torsion spring 66 is fixedly connected to the upper hole wall of the strip-shaped hole 621, and the other end of the torsion spring 66 is fixedly connected to the hole wall of the communication hole 33 close to the bottom column 52; when the flange 41 is not installed on the bottom column 52, the support spring 51 is in a natural state, at this time the torsion spring 66 is in a natural state, one end of the rotating rod 62 close to the pressing plate 65 inclines away from the bottom column 52, and one end of the rotating rod 62 close to the mating plate 63 inclines towards the bottom column 52, the driving rod 64 is located above the mating plate 63, and a limiting member 7 for restricting the rotation of the rotating rod 62 is further arranged in the cavity 32.

[0042] When the flange 41 moves between the bottom column 52 and the fixed block 56, the operator continues to press the satellite 4 downwards, the flange 41 moves downwards and presses the bottom column 52 to move into the installation groove 31, the movement of the bottom column 52 drives the driving rod 64 to move downwards along the sliding hole 34, the driving rod 64 moves downwards and pushes the mating plate 63 to move downwards, while the mating plate 63 moves downwards, it drives the rotating rod 62, the rotating shaft 61 and the pressing plate 65 to rotate, so that the pressing plate 65 moves towards the flange 41, and the torsion spring 66 deforms when the rotating rod 62 rotates; when the rotating rod 62 rotates to the vertical state, the pressing plate 65 is horizontal, the pressing plate 65 is located above the flange 41, at this time the limiting member 7 works to limit the position of the rotating rod 62, so that the rotating rod 62 maintains the vertical state.

[0043] The operator stops pressing the satellite 4, at this time the support spring 51 resumes deformation and pushes the bottom column 52, the driving rod 64 and the satellite 4 to move upwards, the driving rod 64 is separated from the mating plate 63, the movement of the satellite 4 drives the flange 41 to move, when the flange 41 contacts the pressing plate 65, the support spring 51 is still in a compressed state, and the flange 41 abuts against the pressing plate 65; the pressing plate 65 and the fixed block 56 fix the flange 41 at the same time, so that the flange 41 can be better fixed on the mounting plate 3, reducing the situation that the satellite 4 detaches from the mounting plate 3.

[0044] Refer to Figure 4 And Figure 5, the limiting member 7 includes a support plate 71 disposed in the cavity 32. The support plate 71 is located below the mating plate 63. A plurality of guide rods 72 are slidably inserted into the lower surface of the support plate 71. The guide rods 72 penetrate through the lower surface of the mounting plate 3 and are slidably inserted into the mounting plate 3. In this embodiment, the number of guide rods 72 is two. A return spring 73 is sleeved on the guide rod 72. The return spring 73 is located in the cavity 32. The upper end of the return spring 73 is fixedly connected to the lower surface of the support plate 71, and the upper end of the return spring 73 is fixedly connected to the bottom wall of the cavity 32. When the torsion spring 66 and the support spring 51 are both in the natural state, the return spring 73 is in the natural state, and the upper surface of the support plate 71 contacts the mating plate 63.

[0045] A mating groove 711 is formed on the upper surface of the support plate 71. A magnetic plate 74 is fixedly connected to each groove wall of the mating groove 711. A limiting groove 631 corresponding to the mating groove 711 is formed on the lower surface of the mating plate 63. A limiting spring 76 is fixedly connected to the bottom wall of the limiting groove 631. A limiting block 77 is slidably inserted into the limiting groove 631. The material of the limiting block 77 is magnetic metal. The limiting block 77 is fixedly connected to the limiting spring 76. The limiting block 77 is adapted to the groove formed by a plurality of magnetic plates 74 in the mating groove 711. When the limiting spring 76 is in the natural state, the side of the limiting block 77 away from the limiting spring 76 is located outside the limiting groove 631. When the rotating rod 62 is in the vertical state, the mating plate 63 is in the horizontal state, the limiting groove 631 is aligned with the mating groove 711, the limiting block 77 is inserted into the limiting groove 631, and each magnetic plate 74 contacts the corresponding side wall of the limiting block 77. The magnetic plate 74 adsorbs the limiting block 77 to fix the limiting block 77 in the limiting groove 631.

[0046] Refer to Figure 6 , when the flange 41 presses the bottom column 52 and the driving rod 64 downward, the driving rod 64 presses the mating plate 63 downward. While the mating plate 63 moves, it rotates. When the limiting block 77 contacts the upper surface of the support plate 71, as the mating plate 63 continues to move, the support plate 71 presses the limiting block 77 to move into the limiting groove 631. While the limiting block 77 moves, it compresses the limiting spring 76. The support plate 71 moves and presses the support plate 71 and the guide rod 72 downward. The movement of the support plate 71 compresses the return spring 73. When the rotating rod 62 is in the vertical state, the limiting groove 631 is aligned with the mating groove 711. At this time, the limiting spring 76 resumes deformation and pushes the limiting block 77 to move into the mating groove 711. When the surface of the limiting block 77 away from the limiting spring 76 contacts the corresponding magnetic plate 74, the limiting spring 76 is still in the compressed state. The magnetic plate 74 adsorbs the limiting block 77 to fix the limiting block 77. The cooperation between the limiting block 77 and the mating groove 711 keeps the rotating rod 62 vertical, so that the pressing plate 65 keeps the flange 41 fixed.

[0047] A connecting rod 75 is fixedly connected to a plurality of guide rods 72 on a pallet 71. The connecting rod 75 is located at the lower end of the guide rods 72 and is below the mounting plate 3. The length direction of the connecting rod 75 is arranged along the radial direction of the mounting plate 3. One ends of the plurality of connecting rods 75 close to each other are fixedly connected. After the satellite 4 attitude conversion test is completed, the operator needs to remove the satellite 4 from the mounting plate 3. At this time, the operator pulls the connecting rod 75 downward, and the movement of the connecting rod 75 drives the guide rods 72 and the pallet 71 to move downward. The movement of the pallet 71 further compresses the return spring 73, and at the same time, the limit block 77 gradually disengages from the mating groove 711.

[0048] As the pallet 71 continues to move, when the limit block 77 disengages from the limit groove 631, the torsion spring 66 resumes deformation and drives the rotating rod 62 to rotate. When the torsion spring 66 resumes deformation, the pressing plate 65 rotates to disengage from the flange 41. At this time, the supporting spring 51 resumes deformation and pushes the bottom column 52 and the flange 41 upward. When the supporting spring 51 returns to its natural state, the operator pushes the fixing block 56 into the groove 541; after the fixing block 56 is located in the groove 541, the satellite 4 is pulled upward until the mounting block 54 disengages from the flange 41. At this time, the satellite 4 is disengaged from the mounting plate 3.

[0049] The implementation principle of a satellite attitude conversion device in an embodiment of the present application is as follows: When it is necessary to fix the satellite 4, the operator aligns the mating hole 411 with the support rod 53 and delivers the satellite 4 downward. The mating groove 711 causes the fixing block 56 to move into the groove 541. When the mating groove 711 moves outside the mounting plate 3, the flange 41 contacts the upper end surface of the bottom column 52, and the fixing block 56 moves out of the groove 541. The fixing block 56 cooperates with the bottom column 52 to fix the flange 41; the operator continues to press the satellite 4 downward, and the flange 41 presses the bottom column 52 and the driving rod 64 downward. The movement of the bottom rod compresses the supporting spring 51, and the movement of the driving rod 64 presses the mating plate 63 to rotate. The rotation of the mating plate 63 drives the rotating rod 62 and the pressing plate 65 to rotate. At the same time, the mating plate 63 presses the pallet 71 downward, and the pallet 71 presses the limit block 77 to move into the limit groove 631. The movement of the limit block 77 compresses the limit spring 76.

[0050] When the rotating rod 62 is in a vertical state, the pressing plate 65 is above the flange 41, the limit groove 631 is aligned with the mating groove 711, and the limit spring 76 resumes deformation and pushes the limit block 77 into the mating groove 711. The magnetic plate 74 adsorbs the limit block 77 to fix the limit block 77; at this time, the operator stops pressing the satellite 4, and the supporting spring 51 resumes deformation and pushes the pressing plate 65 upward until the flange 41 abuts against the pressing plate 65.

[0051] When it is necessary to remove the satellite 4, pull the connecting rod 75 downward. The connecting rod 75 drives the guide rod 72 and the support plate 71 to move downward. When the limit block 77 disengages from the mating groove 711, the torsion spring 66 resumes deformation and drives the rotating rod 62 to rotate. When the torsion spring 66 resumes to its natural state, the pressing plate 65 disengages from the flange 41. At this time, the support spring 51 resumes deformation and pushes the flange 41 and the satellite 4 upward; when the support spring 51 resumes to its natural state, push the fixing block 56 into the groove 541 until the fixing block 56 is completely located within the groove 541. At this time, pull the satellite 4 upward until the mounting block 54 disengages from the flange 41, thereby removing the satellite 4 from the mounting plate 3.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
