[0047] Please refer to Figures 1 to 3, embodiments of the present application provide a testing device. For example, the testing device may refer to a probe station or other testing devices.

[0048] The testing device includes a main body and a locking assembly 100. The locking assembly 100 can be used to lock an object to facilitate operations on the object. For example, the locking assembly 100 can be used to clamp a test cassette 200 for testing semiconductor devices, so as to facilitate the testing of semiconductor devices. In this way, the probe station integrates the locking assembly 100 for locking the test cassette 200, which helps the probe station to test semiconductor devices more stably.

[0049] The locking assembly 100 can achieve quick locking and unlocking to replace different test cassettes 200 for different tests of semiconductor devices.

[0050] In some embodiments, the locking assembly 100 includes at least two locking structures 110 and a base 120. The at least two locking structures 110 are both connected to the base 120, and the locking structure 110 can be used to lock or unlock an object.

[0051] The base 120 is installed on the main body to install the locking assembly 100 on the main body.

[0052] Among them, the at least two locking structures 110 can lock the object more stably. The at least two locking structures 110 can be distributed on opposite sides of the base 120 to clamp the object more stably.

[0053] The at least two locking structures 110 can refer to two locking structures 110, three locking structures 110, four locking structures 110, five locking structures 110 or other numbers of locking structures 110.

[0054] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments, the locking structure 110 includes a mounting seat 111, a clamping assembly 112 and a first driving member 113.

[0055] Among them, the mounting seat 111 is connected to the base 120, and the locking structure 110 can be fixed to the base 120 through the mounting seat 111.

[0056] For example, the mounting seat 111 and the base 120 can be connected and fixed through a fixing member, or the mounting seat 111 can be snap-fitted to the base 120, the cooperation and the mounting seat 111 can be welded to the base 120, or the mounting seat 111 can also be connected to the base 120 in other ways. Among them, the fixing member can adopt screws, bolts, rivets or other fixing structures.

[0057] The clamping assembly 112 is movably connected to the mounting base 111. The clamping assembly 112 has a first position (as shown in Figure 4 ), and a second position (as shown in Figure 5 ).

[0058] The clamping assembly 112 includes a clamping member 1120 for clamping. When the clamping assembly 112 moves, the clamping member 1120 moves synchronously.

[0059] It can be understood that when the clamping assembly 112 is in the first position, the clamping member 1120 can also be in the first position; when the clamping assembly 112 is in the second position, the clamping member 1120 can also be in the second position.

[0060] When the clamping assembly 112 moves to the first position, the clamping member 1120 is in an open state (as shown in Figure 4 ), so that an object can be released. When the clamping assembly 112 moves to the second position, the clamping member 1120 is in a clamping state (as shown in Figure 5 ), so that an object can be clamped.

[0061] The first driving member 113 is movably connected to the mounting base 111. The clamping assembly 112 is connected to the first driving member 113. When the first driving member 113 moves, it drives the clamping assembly 112 to move. In this way, when the first driving member 113 moves, it can drive the clamping member 1120 to be in an open state or a clamping state, so that the locking structure 110 can quickly lock and quickly release an object, with a simple structure and easy operation.

[0062] In some embodiments, when the first driving member 113 moves along the first direction X, it can drive the clamping assembly 112 to move along the second direction Y. The first direction X and the second direction Y are arranged at an angle, so that it is more convenient to drive the clamping assembly 112 to move. For example, the first direction X and the second direction Y can be substantially perpendicular.

[0063] As an example, the first direction X is substantially parallel to the horizontal direction, and the second direction Y is substantially parallel to the vertical direction. In this way, when the staff is working, the staff can push or pull the first driving member 113 to move along the horizontal direction, and the clamping assembly 112 can be driven to move. When the staff applies a force to the first driving member 113, it can be more convenient and labor-saving.

[0064] It can be understood that the first driving member 113 can be manually driven, and the first driving member 113 can also be driven by a driving structure. The driving end of the driving structure can be connected to the first driving member 113, and the driving structure can be used to drive the first driving member 113 to move back and forth. For example, the driving structure can adopt a linear servo or other driving structures for linear motion.

[0065] Please refer toFigures 1 to 3 In some embodiments, the locking assembly 100 may further include a second driving member 130. The first driving members 113 of at least two locking structures 110 are all connected to the second driving member 130. When the second driving member 130 moves, it drives the first driving members 113 to move. In this way, when the second driving member 130 moves, it can drive the first driving members 113 of multiple locking structures 110 to move synchronously, so that it is not necessary to operate multiple first driving members 113, which helps the locking assembly 100 to be more convenient to use.

[0066] In some embodiments, at least two locking structures 110 may be distributed on opposite sides of the base 120 and spaced apart to form a space for placing the object to be clamped.

[0067] As an example, taking four locking structures 110 as an example, the four locking structures 110 may be respectively named the first locking structure, the second locking structure, the third locking structure, and the fourth locking structure. The first locking structure and the second locking structure may be located on the first side of the base 120, and the third locking structure and the fourth locking structure may be located on the second side of the base 120, and the first side and the second side are opposite. The second driving member 130 may include a first driving portion, a connecting portion, and a second driving portion connected in sequence. The first driving portion and the connecting portion may be arranged at an angle, and the connecting portion and the second driving portion may be arranged at an angle. The first driving portion, the connecting portion, and the second driving portion enclose a space for placing the object to be clamped.

[0068] Among them, the first driving members 113 of the first locking structure and the second locking structure are both connected to the first driving portion, and the first driving members 113 of the third locking structure and the fourth locking structure are both connected to the second driving portion. The locking assembly 100 may further include a handle 140 that is convenient to grip. The handle 140 may be connected to the side of the second driving member 130 facing away from the base 120. The staff can drive the second driving member 130 to move back and forth along the first direction X through the handle 140, so as to drive the four first driving members 113 to drive back and forth along the first direction X at the same time, thereby driving the four clamping assemblies 112 to move back and forth along the second direction Y.

[0069] At least one of the first driving portion, the connecting portion, and the second driving portion is connected to the handle 140.

[0070] Please refer to Figures 3 to 5 In some embodiments, the locking assembly 100 may further include a loosening prevention assembly 150. The loosening prevention assembly 150 may be connected between the second driving member 130 and the base 120.

[0071] The second driving member 130 may have a third position and a fourth position.

[0072] Among them, as Figure 4and Figure 6 As shown, the second driving member 130 is in the third position, and the clamping assembly 112 is in the first position. As Figure 5 and Figure 7 shown, the second driving member 130 is in the fourth position, and the clamping assembly 112 is in the second position.

[0073] The anti-loosening assembly 150 is used to maintain the second driving member 130 in the third position or the fourth position. Thus, the anti-loosening assembly 150 can position the second driving member 130, so that the clamping assembly 112 can be stably maintained in the first position or the second position, making it more convenient for the staff to operate.

[0074] In some embodiments, the anti-loosening assembly 150 includes an anti-loosening member 151 and a second elastic member 153. The anti-loosening member 151 is rotatably connected to the second driving member 130. The anti-loosening member 151 is provided with a first clamping groove 1515 and a second clamping groove 1517 distributed along the moving direction of the second driving member 130.

[0075] The base 120 is provided with a clamping member 121 located on the moving path of the anti-loosening member 151, so that the first clamping groove 1515 and the second clamping groove 1517 can be clamped with the clamping member 121.

[0076] When the second driving member 130 is in the third position, the first clamping groove 1515 is clamped with the clamping member 121. In this way, the second driving member 130 can be maintained in the third position.

[0077] When the second driving member 130 is in the fourth position, the second clamping groove 1517 is clamped with the clamping member 121. In this way, the second driving member 130 can be maintained in the fourth position.

[0078] The second elastic member 153 abuts between the anti-loosening member 151 and the second driving member 130, and is used to drive the anti-loosening member 151 to abut against the clamping member 121, thereby helping the first clamping groove 1515 to be more stably clamped with the clamping member 121, and helping the second clamping groove 1517 to be more stably clamped with the clamping member 121.

[0079] As an example, the anti-loosening member 151 may include a first section 1511 and a second section 1513 arranged at an angle. The connection position between the first section 1511 and the second section 1513 may be hinged to the second driving member 130. The first clamping groove 1515 and the second clamping groove 1517 may be provided on the first section 1511. The second elastic member 153 may abut between the second section 1513 and the second driving member 130. The second elastic member 153 may push the second section 1513 to rotate, so as to drive the first section 1511 to rotate in the same direction, so that the first section 1511 can abut against the clamping member 121.

[0080] As Figure 4As shown, when the second driving member 130 is in the third position, the first engaging groove 1515 is engaged with the engaging member 121, and the clamping assembly 112 is in the first position, and the clamping member 1120 is in an open state. Taking the test box 200 as an example, the side of the test box 200 may be provided with a fixed shaft 210 (such as Figure 2 As shown in FIG. 1 ), the fixed shaft 210 can be placed in the clamping member 1120. The test box 200 can be provided with fixed shafts 210 on opposite sides, and each fixed shaft 210 can be clamped by a clamping member 1120. It can be understood that the number of locking structures 110 can be equal to the number of fixed shafts 210, so that each fixed shaft 210 can be clamped by a clamping member 1120. It should be noted that Figure 1 and Figure 2 In the embodiment, the fixing shaft 210 of the test box 200 is in a state of being separated from the clamping member 1120 , or the fixing shaft 210 of the test box 200 is in a state of being ready to be placed in the clamping member 1120 .

[0081] When the test box 200 needs to be clamped, the staff can press the end of the second section 1513 away from the first section 1511, and the second elastic member 153 is compressed to provide a rotation space for the second section 1513. The second section 1513 drives the first section 1511 to rotate, and the first section 1511 rotates to the side away from the clamping member 121, so that the first clamping groove 1515 is separated from the clamping member 121. At this time, the second driving member 130 can be pushed to move along the first direction X. Figure 5 As shown, when the second driving member 130 moves to the fourth position, the second clamping groove 1517 of the anti-loosening member 151 is clamped on the clamping member 121. At this time, the clamping assembly 112 is in the second position, the clamping member 1120 is in the clamping state, and the clamping member 1120 clamps the fixed shaft 210 (such as Figure 1 The second clamping groove 1517 of the anti-loosening member 151 is clamped on the clamping member 121, and the second elastic member 153 pushes the anti-loosening rod so that the second clamping groove 1517 abuts against the clamping member 121, which helps the second driving member 130 to maintain the fourth position.

[0082] When the test box 200 needs to be released, the staff can press the end of the second section 1513 away from the first section 1511, and the second elastic member 153 is compressed to provide a rotation space for the second section 1513. The second section 1513 drives the first section 1511 to rotate, and the first section 1511 rotates to the side away from the clamping member 121, so that the second clamping groove 1517 is separated from the clamping member 121. At this time, the second driving member 130 can be pushed to move along the side away from the first direction X. Figure 4As shown, when the second driving member 130 moves to the third position, the first engaging groove 1515 of the anti-loosening member 151 engages with the engaging member 121. At this time, the clamping assembly 112 is in the first position, the clamping member 1120 is in the open state, and the clamping member 1120 releases the fixed shaft 210. The staff can remove or replace the test box 200. The first engaging groove 1515 of the anti-loosening member 151 engages with the engaging member 121, and the second elastic member 153 pushes the anti-loosening rod, so that the first engaging groove 1515 abuts against the engaging member 121, which helps the first driving member 113 to maintain in the third position.

[0083] Please refer to Figures 4 to 5 , in some embodiments, the anti-loosening assembly 150 may further include a fixing block 155 and a guide sleeve 157. The fixing block 155 may be connected to the second driving member 130. For example, the fixing block 155 may be connected to the side of the second driving member 130 facing the base 120. The fixing block 155 may be provided with a mounting groove, and the mounting groove may extend along the first direction X. The guide sleeve 157 may be located in the mounting groove. One end of the second elastic member 153 may be inserted into the guide sleeve 157, and the other end of the second elastic member 153 may be exposed outside the guide sleeve 157 to abut against the anti-loosening rod. Specifically, the end of the second elastic member 153 exposed outside the guide sleeve 157 may abut against the first section 1511 of the anti-loosening rod.

[0084] Please refer to Figures 7 to 9 , in some embodiments, the clamping assembly 112 may further include a guide block 1140. The guide block 1140 is movably connected to the mounting seat 111. The clamping member 1120 is connected to the guide block 1140, and the first driving member 113 is connected to the guide block 1140 to drive the guide block 1140 to move back and forth between the first position and the second position. In this way, the first driving member 113 can drive the guide block 1140 to move, and when the guide block 1140 moves, it drives the clamping member 1120 to move, so that the clamping member 1120 can move back and forth between the first position and the second position.

[0085] As an example, the mounting seat 111 may be provided with a first sliding groove, and the guide block 1140 is slidably located in the first sliding groove. The first driving member 113 can drive the guide block 1140 to move back and forth in the first sliding groove.

[0086] In some embodiments, the clamping member 1120 may include two clamping portions 1121 arranged oppositely. The same side of the two clamping portions 1121 both has a clamping end 1123; the two clamping portions 1121 are rotatably connected to the guide block 1140, and the two clamping portions 1121 rotate to change the distance between the two clamping ends 1123.

[0087] As an example, the clamping portion 1121 may include a hinged end 1125 and a clamping end 1123, and the hinged end 1125 and the clamping end 1123 are respectively located at opposite ends of the clamping portion 1121. The hinged ends 1125 of the two clamping portions 1121 can be hinged to the guiding block 1140. The two hinged ends 1125 can be coaxially hinged or non-coaxially hinged. The rotation axes of the two clamping portions 1121 are parallel or coincident. When the two hinged ends 1125 rotate, they drive the two clamping ends 1123 to rotate, so as to change the distance between the two clamping ends 1123.

[0088] Wherein, when the clamping member 1120 is in the open state, the distance between the two clamping ends 1123 is greater than the distance between the two clamping ends 1123 when the clamping member 1120 is in the clamping state. When the clamping member 1120 is in the open state, the two clamping ends 1123 move away from each other to release an object; when the clamping member 1120 is in the clamping state, the two clamping ends 1123 approach or the two clamping ends 1123 come into contact to clamp an object.

[0089] In some embodiments, the guiding block 1140 may be provided with a placement groove, and the fixed shaft 210 can be placed in the placement groove. The notch of the placement groove can face the second direction Y, and the bottom wall of the placement groove can support the fixed shaft 210. When the fixed shaft 210 is placed in the placement groove, the fixed shaft 210 can partially extend between the two clamping portions. Thus, when the two clamping ends 1123 approach, the fixed shaft 210 can be clamped, and when the two clamping ends 1123 move away from each other, the fixed shaft 210 can be released.

[0090] In some embodiments, the two clamping portions 1121 rotate towards each other to drive the two clamping ends 1123 to approach each other; the two clamping portions 1121 rotate away from each other to drive the two clamping ends 1123 to move away from each other.

[0091] Specifically, the hinged ends 1125 of the two clamping portions 1121 rotate towards each other to drive the distance between the two clamping ends 1123 to decrease, so as to clamp an object; the hinged ends 1125 of the two clamping portions 1121 rotate away from each other to drive the distance between the two clamping ends 1123 to increase, so as to release the object.

[0092] In some embodiments, the clamping assembly 112 may further include a first elastic member 1150. The first elastic member 1150 can abut between the two clamping portions 1121, and the first elastic member 1150 is used to drive the two clamping ends 1123 to open.

[0093] As an example, the guiding block 1140 may be provided with a protruding portion, which may be located between the two clamping portions 1121. The protruding portion may be provided with a through hole, and the first elastic member 1150 may pass through the through hole. Both ends of the first elastic member 1150 respectively abut against one clamping portion 1121. The hole wall of the through hole can limit the first elastic member 1150, which helps to prevent the first elastic member 1150 from deforming, popping out or failing after being squeezed. It can be understood that avoidance grooves may be provided on the opposite sides of the two clamping portions 1121 to avoid the protruding portion, and the protruding portion may be located between the two avoidance grooves.

[0094] Among them, the first elastic member 1150 may adopt a spring or other elastic structure.

[0095] Please refer to Figure 5 and Figure 9 In some embodiments, the locking structure 110 may further include two limiting members 114 arranged oppositely. Both limiting members 114 are connected to the mounting base 111 and are respectively located on the left and right sides of the moving direction of the clamping member 1120. The two clamping portions 1121 respectively abut against one limiting member 114. The two limiting members 114 are used to drive the two clamping ends 1123 to approach. When the clamping member 1120 is in the open state, the distance between the clamping ends 1123 and the limiting members 114 is greater than the distance between the clamping ends 1123 and the limiting members 114 when the clamping member 1120 is in the clamping state. Thus, the limiting members 114 can make the two clamping ends 1123 approach to clamp an object.

[0096] As an example, for the convenience of description, the two clamping portions 1121 are respectively named the first clamping portion and the second clamping portion, and the two limiting members 114 are respectively named the first limiting member and the second limiting member. The first clamping portion and the second clamping portion are located between the first limiting member and the second limiting member. The first clamping portion may abut against the first limiting member, and the second clamping portion may abut against the second limiting member. For example, the first elastic member 1150 may push the first clamping portion to abut against the first limiting member and push the second clamping portion to abut against the second limiting member. When the clamping assembly 112 moves to the open state (as shown in Figure 4 ), the two clamping ends 1123 are in a position far from the limiting members 114 (as shown in Figure 5 ), and the first elastic member 1150 can push the two clamping ends 1123 to open; when the clamping assembly 112 moves to the clamping state, the two clamping ends 1123 approach the limiting members 114, or the two clamping ends 1123 are located between the two limiting members 114. Since the distance between the two limiting members 114 remains unchanged, the limiting members 114 can make the two clamping ends 1123 approach to clamp an object.

[0097] In some embodiments, both of the two limiting members 114 are rotatably connected to the mounting base 111, and the limiting members 114 are adapted to roll on the clamping portion 1121, thereby helping the clamping assembly 112 to move more smoothly.

[0098] As an example, when the clamping assembly 112 moves, the first clamping portion moves relative to the first limiting member, and the first limiting member rolls on the first clamping portion, which helps to avoid interference between the first limiting member and the first clamping portion. Similarly, the second clamping portion moves relative to the second limiting member, and the second limiting member rolls on the second clamping portion, which helps to avoid interference between the second limiting member and the second clamping portion.

[0099] In some embodiments, both the first limiting member and the second limiting member can be bearings to reduce the manufacturing cost and design cost of the locking structure 110.

[0100] As an example, the first connecting member can be a connecting shaft. The locking structure 110 can further include two first connecting members, and the two first connecting members can be connected to the mounting base 111. The inner ring of the bearing can be sleeved outside the first connecting member, and the outer ring of the bearing can be used to abut against the clamping portion 1121 and roll on the clamping portion 1121.

[0101] In some embodiments, at least one of the two clamping portions 1121 can be provided with a positioning groove 1127. When the clamping assembly 112 is in the first position, at least one of the two limiting members 114 is clamped in the positioning groove 1127 of the corresponding clamping portion 1121. Thus, the positioning groove 1127 can limit the limiting member 114, so that the clamping member 1120 can be kept in the open state, facilitating the placement of the object to be fixed into the clamping member 1120, and thus facilitating the clamping member 1120 to perform clamping.

[0102] Specifically, it is convenient to place the object to be fixed between the two clamping ends 1123, thus facilitating the clamping member 1120 to perform clamping.

[0103] As an example, a positioning groove 1127 can be provided on the side of the first clamping portion facing away from the second clamping portion, and a positioning groove 1127 can also be provided on the side of the second clamping portion facing away from the first clamping portion. The two positioning grooves 1127 can be arranged oppositely. When the clamping assembly 112 moves to the first position, the first limiting member can be partially inserted into the positioning groove 1127 of the first clamping portion, and the second limiting member can be partially inserted into the positioning groove 1127 of the second clamping portion, thereby positioning the clamping assembly 112 so that the clamping assembly 112 can be kept in the first position.

[0104] Please refer to Figures 6 to 8In some embodiments, the clamping assembly 112 may further include a transmission member 1160, and the first driving member 113 has two cam surfaces arranged opposite to each other; one end of the transmission member 1160 is connected to the guide block 1140, and the other end of the transmission member 1160 is against the two cam surfaces; the first driving member 113 moves back and forth along the first direction X, driving the transmission member 1160 to be at different positions of the two cam surfaces along the first direction X, and the two cam surfaces are used to drive the transmission member 1160 to move back and forth along the second direction Y, so that the clamping assembly 112 moves back and forth between the first position and the second position. In this way, when the first driving member 113 moves, the cam surface can push the transmission member 1160 to move along the second direction Y, so that the clamping assembly 112 can move back and forth between the first position and the second position.

[0105] As an example, the first driving member 113 may be provided with a driving through hole, and the driving through hole has two opposite hole walls along the second direction Y, and the two hole walls may refer to two cam surfaces. For the convenience of description, the two cam surfaces are respectively named as the first cam surface 1131 and the second cam surface 1133. The transmission member 1160 may be partially inserted into the driving through hole, and the outer peripheral surface of the transmission member 1160 may abut between the first cam surface 1131 and the second cam surface 1133. When the first driving member 113 moves along the first direction X, the first cam surface 1131 pushes the transmission member 1160 to move along the second direction Y, driving the clamping assembly 112 to move along the second direction Y, so that the clamping assembly 112 can move to the first position; when the first driving member 113 moves to the side away from the first direction X, the second cam surface 1133 pushes the transmission member 1160 to move along the side away from the second direction Y, driving the clamping assembly 112 to move along the side away from the second direction Y, so that the clamping assembly 112 can move to the second position.

[0106] The height of the cam surface along the second direction Y can be changed, so that the cam surface can drive the transmission member 1160 to move along the second direction Y.

[0107] The cam surface may have various forms, for example, the cam surface may be an arc surface, the cam surface may be a plurality of planes connected in sequence, or the cam surface may be an inclined surface, or the cam surface may be other types of surfaces.

[0108] It can be understood that the cam surface can be a continuous surface, or the cam surface can be formed by connecting multiple surfaces in sequence.

[0109] In some embodiments, the mounting seat 111 may be provided with a limiting hole 1111, the transmission member 1160 is inserted through the limiting hole 1111, and the transmission member 1160 is adapted to move back and forth along the second direction Y within the limiting hole 1111; when the clamping assembly 112 is in the first position and the second position, the transmission member 1160 is respectively located on opposite sides of the limiting hole 1111 along the second direction Y and both abut against the mounting seat 111. In this way, the hole walls on both sides of the limiting hole 1111 along the second direction Y can limit the movement of the transmission member 1160, which helps to limit the stroke of the transmission member 1160 and helps to prevent the clamping assembly 112 from detaching from the mounting seat 111.

[0110] Among them, the shape of the limiting hole 1111 can be designed according to requirements. For example, the limiting hole 1111 includes a first hole, a second hole, and a third hole that are sequentially distributed along the second direction Y, the first hole and the second hole partially overlap, and the second hole and the third hole partially overlap. When the clamping assembly 112 is in the first position, the transmission member 1160 abuts against the hole wall of the third hole; when the clamping assembly 112 is in the second position, the transmission member 1160 abuts against the hole wall of the first hole.

[0111] In some embodiments, the clamping assembly 112 may further include a first rolling member 1170, the first rolling member 1170 is rotatably connected to the transmission member 1160, the first rolling member 1170 abuts between two cam surfaces and is adapted to roll on the cam surfaces, which helps the first driving member 113 to move more smoothly and helps to improve the situation where the first driving member 113 moves stuck or cannot move due to the interference between the transmission member 1160 and the cam surfaces.

[0112] As an example, the transmission member 1160 may be a transmission shaft. The first rolling member 1170 may be a bearing, the inner ring of the bearing may be sleeved outside the transmission member 1160, and the outer ring of the bearing may be used to abut against two cam surfaces and roll on the two cam surfaces.

[0113] In some embodiments, the locking structure 110 further includes two second rolling members 115 arranged along the first direction X, and both of the two second rolling members 115 are rotatably connected to the mounting seat 111; the first driving member 113 is connected to the two second rolling members 115, and the two second rolling members 115 are adapted to provide guidance for the movement of the first driving member 113 along the first direction X and are adapted to roll on the first driving member 113. In this way, the two second rolling members 115 can support the first driving member 113 and help the first driving member 113 to move more smoothly.

[0114] As an example, both of the two second rolling members 115 may be bearings. The locking structure 110 may further include two second connecting members. One end of the second connecting member may be connected to the mounting seat 111, and the inner ring of the second rolling member 115 may be sleeved on the other end of the second connecting member. The first driving member 113 may be provided with a second chute extending along the first direction X, and the two second rolling members 115 may be located in the second chute. The second chute has two opposite groove side walls along the second direction Y, and both of the two second rolling members 115 abut between the two groove side walls and roll on the two groove side walls.

[0115] In the locking structure 110, the locking assembly 100, and the testing device provided by the embodiments of the present application, the clamping assembly 112 is movably connected to the mounting seat 111. The clamping assembly 112 includes a clamping member 1120 for clamping. When the clamping assembly 112 moves, the clamping member 1120 moves synchronously. When the clamping assembly 112 moves to the first position, the clamping member 1120 is in an open state, so that an object can be released; when the clamping assembly 112 moves to the second position, the clamping member 1120 is in a clamping state, so that an object can be clamped. The first driving member 113 is movably connected to the mounting seat 111, the clamping assembly 112 is connected to the first driving member 113, and the movement of the first driving member 113 can drive the clamping assembly 112 to move back and forth between the first position and the second position, so that the clamping member 1120 can be in an open state or a clamping state, so that the locking structure 110 can achieve rapid locking and rapid release of an object, with a simple structure and easy operation.

However, the present invention is not limited to the above embodiments.
