Referring to fig. 1 and fig. 2, an embodiment of the invention provides a detection fixture for clamping a product a to detect the product a. The detection tool comprises a mounting bracket 10, a clamping component 20, a supporting component 30 and a linkage component 40.

The clamping assembly 20 includes a fixed clamping portion 21 and a movable clamping portion 22 spaced apart from each other along the first direction X in the mounting bracket 10. The fixed and

movable clamping portions

21 and 22 form a clamping position (not shown) therebetween for clamping the product a, and the movable clamping portion 22 is configured to be operatively close to or away from the fixed clamping portion 21. When the movable clamping part 22 moves close to the fixed clamping part 21, the product A at the clamping position can be clamped; the product a at the clamping position can be released (i.e., the clamping of the product a is released) when the movable clamping portion 22 moves away from the fixed clamping portion 21. The support assembly 30 includes a first support 31 and a second support 32 disposed on the mounting bracket 10. The first support 31 and the second support 32 are respectively located at two sides of the clamping position in a second direction Y, which intersects with the first direction X. Preferably, the second direction Y is perpendicular to the first direction X.

The movable clamping portion 22 is in transmission connection with the first support 31 and the second support 32 through the linkage assembly 40. When the movable clamping portion 22 moves away from the fixed clamping portion 21, the linking assembly 40 drives the first supporting member 31 and the second supporting member 32 to move close to each other, so as to support the product a located at the clamping position; when the movable clamping portion 22 moves close to the fixed clamping portion 21, the linking assembly 40 drives the first supporting member 31 and the second supporting member 32 to move away from each other, so as to release the support of the product a located at the clamping position.

Above-mentioned detection tool, when needs clamping product A, at first, control activity clamping part 22 and keep away from fixed clamping part 21 and remove to drive first support piece 31 and second support piece 32 through interlock subassembly 40 simultaneously and be close to each other, until stretching into in the clamping position. At this time, the product a can be placed in the clamping position, and the first supporting member 31 and the second supporting member 32 are used for supporting the product a, so that the product a is prevented from falling. Then, the movable clamping portion 22 is controlled to move close to the fixed clamping portion 21, so that the movable clamping portion 22 and the fixed clamping portion 21 clamp and fix the product a. Meanwhile, the linking assembly 40 drives the first supporting member 31 and the second supporting member 32 to move away from each other until the clamping position is exited, so as to release the support of the product a. When the clamping of the product A needs to be released, the movable clamping part 22 is controlled to move away from the fixed clamping part 21 so as to release the product A. Meanwhile, the linkage assembly 40 drives the first supporting member 31 and the second supporting member 32 to approach each other until the clamping position is reached, so as to support the product a and prevent the product a from falling.

So, utilize activity clamping part 22 and fixed clamping part 21 centre gripping product A, and utilize first support piece 31 and second support piece 32 with activity clamping part 22 linkage to support product A, operating personnel control activity clamping part 22 presss from both sides tightly or loosens and to accomplish the clamping, goes up unloading convenient and fast, is favorable to improving clamping efficiency.

In the embodiment of the present invention, the clamping assembly 20 further includes an operating member 23, and the operating member 23 is disposed on the mounting bracket 10 and located on a side of the movable clamping portion 22 away from the fixed clamping portion 21. The operating member 23 is movable in the first direction X to a clamping position (see fig. 2) and a release position (see fig. 1) by an external force. When the operating member 23 is moved to the clamping position, the operating member 23 abuts against the movable clamping portion 22, so that the movable clamping portion 22 moves toward the fixed clamping portion 21 to clamp the product a at the clamping position. When the operating member 23 moves to the release position, the operating member 23 drives the movable clamping portion 22 to move away from the fixed clamping portion 21, so that the movable clamping portion 22 and the fixed clamping portion 21 release the clamping of the product a.

So, when needing clamping product A, at first, promote operating parts 23 and remove to the unclamping position along first direction X, operating parts 23 drive activity clamping part 22 and keep away from fixed clamping part 21 and remove to drive first support piece 31 and second support piece 32 through linkage assembly 40 simultaneously and be close to each other, until stretching into in the centre gripping position. At this time, the product a can be placed in the clamping position, and the first supporting member 31 and the second supporting member 32 are used for supporting the product a, so that the product a is prevented from falling. Then, the pushing operation member 23 moves along the first direction X to the clamping position, at which time the operation member 23 abuts against the movable clamping portion 22, so that the movable clamping portion 22 moves close to the fixed clamping portion 21 until the movable clamping portion 22 and the fixed clamping portion 21 clamp and fix the product a. Meanwhile, the first supporting member 31 and the second supporting member 32 are driven to move away from each other by the linkage assembly 40 until the clamping position is withdrawn, so that the product a is released from being supported.

When the clamping of the product A needs to be released, the operating piece 23 is pushed to move to the releasing position, so that the operating piece 23 drives the movable clamping part 22 to move away from the fixed clamping part 21, and the product A is released. Meanwhile, the linkage assembly 40 drives the first supporting member 31 and the second supporting member 32 to approach each other until the clamping position is reached, so as to support the product a and prevent the product a from falling. That is to say, move between unclamping position and clamping position through pushing operating parts 23, realize the clamping to product A and remove the clamping, convenient operation is swift, is favorable to promoting clamping efficiency.

It should be noted that the movement of the operating member 23 between the release position and the clamping position is not limited to the pushing and pulling by the operator, and may be automated. For example, in one embodiment, the clamping assembly 20 further includes a first actuating member mounted to the mounting bracket 10 and drivingly connected to the operating member 23 to drive the operating member 23 to move between the unclamped position and the clamped position in the first direction X. Alternatively, the first drive member may be a cylinder or the like.

In the embodiment, the clamping assembly 20 further includes a first elastic member 24, and the first elastic member 24 is disposed on a side of the movable clamping portion 22 facing the operating member 23. When the operating member 23 is moved to the clamping position, the operating member 23 abuts against the movable clamping portion 22 through the first elastic member 24 (at this time, the first elastic member 24 is in a compressed state) to push the movable clamping portion 22 to clamp the product a, and provide a clamping force to the movable clamping portion 22 to keep clamping the product a. When the operating member 23 moves to the release position, the operating member 23 is separated from the first elastic member 24 (at this time, the first elastic member 24 is in a natural state), and drives the movable clamping portion 22 to move away from the fixed clamping portion 21, that is, the clamping force of the movable clamping portion 22 for clamping the product a disappears, and the movable clamping portion 22 releases the clamping of the product a. So, the accessible selects the first elastic component 24 of different specifications, adjusts the size of the clamping-force of centre gripping product A to be applicable to and carry out the clamping to the product A of different grade type, promote detection tool's compatibility. Alternatively, the first elastic member 24 may be a spring.

Further, the clamping assembly 20 further includes a first guiding rod 25 and a first sliding block 26, the first guiding rod 25 is fixedly connected to the mounting bracket 10, the first sliding block 26 and the operating member 23 are both slidably connected to the first guiding rod 25, and the movable clamping portion 22 is fixedly connected to the first sliding block 26. It should be noted that the first guide bar 25 is parallel to the first direction X, so that the first slider 26 and the operation member 23 slide along the first guide bar 25, i.e. move along the first direction X. The first slider 26 may be provided with one or more movable clamping portions 22, as long as the product a can be stably clamped, which is not limited herein. Similarly, the fixed clamping portion 21 may include one or more than one, and is not limited herein, as long as the product a can be stably clamped.

It should be noted that, the positions of the movable clamping portions 22 and the fixed clamping portions 21 can be designed according to the shape of the product a to be clamped, so as to match the shape of the product a, and ensure that the product a can be stably clamped. For example, the shape of the product a may be rectangular, circular, oval, etc., and is not limited herein.

Further, the clamping assembly 20 further includes a pull rod 27, one end of the pull rod 27 is fixedly connected to the first slide block 26, and the other end of the pull rod 27 is slidably engaged with the operating member 23. The first elastic element 24 is sleeved on the pull rod 27 and located between the first sliding block 26 and the operating element 23. Thus, when the operating member 23 moves to the clamping position, the operating member 23 abuts against the first slider 26 through the first elastic member 24, so as to drive the movable clamping portion 22 to clamp the product a. When the operating member 23 moves to the release position, the operating member 23 drives the first slider 26 and the movable clamping portion 22 to move away from the fixed clamping portion 21 through the pull rod 27, so as to release the clamping of the product a.

In the embodiment, the linkage assembly 40 includes a first linkage mechanism 41, and the first linkage mechanism 41 includes a first linkage block 410 and a first cam slot plate 411. The first linkage block 410 is movably connected to the mounting bracket 10 along the first direction X and is fixedly connected to the operating member 23 such that the first linkage block 410 can move along the first direction X along with the operating member 23. The first cam groove plate 411 is mounted on the first link block 410, and has a first cam groove B1. The first support 31 has the first follower 34 mounted thereon, and the first follower 34 is slidably fitted with the first cam groove B1. When the operating member 23 moves between the clamping position and the releasing position, the operating member 23 drives the first link block 410 and the first cam groove plate 411 to move along the first direction X, so that the first follower 34 moves along the first cam groove B1 relative to the first cam groove plate 411, and further drives the first support member 31 to move closer to or away from the second support member 32. That is, the linear motion of the operating member 23 in the first direction X is converted into the linear motion of the first support 31 in the second direction Y by the sliding fit of the first follower 34 with the first cam groove B1. Alternatively, the first follower 34 may be a rolling bearing, so that friction between the first follower 34 and the first cam groove plate 411 is reduced, so that the first follower 34 can smoothly move along the first cam groove plate 411.

Specifically, in the embodiment, the supporting assembly 30 further includes a second guiding rod 331 and a first mounting block 33, and the second guiding rod 331 is fixedly connected to the mounting bracket 10 and is parallel to the second direction Y. The first mounting block 33 is slidably coupled to the second guide bar 331. The first support 31 and the first follower 34 are mounted on the first mounting block 33. When the first cam slot plate 411 moves along the first direction X along with the first link block 410, the first follower 34 and the first cam slot B1 cooperate to drive the first mounting block 33 to slide along the second guide rod 331, so that the first supporting member 31 moves along with the first mounting block 33 to support or release the product a. It should be noted that one or more first supporting members 31 may be installed on the first installation block 33 as needed, as long as the product a can be stably supported, and the installation is not limited herein.

Specifically, in the embodiment, the first linking mechanism 41 further includes a second elastic element 412, one end of the second elastic element 412 is connected to the mounting bracket 10, and the other end is connected to the first linking block 410, so as to provide a pre-tightening force for driving the operating element 23 to move from the releasing position to the clamping position by the first linking block 410. Thus, when it is necessary to load the product a to the clamping position (as shown in fig. 3 and 4), the operator pushes the operating member 23 from the clamping position to the releasing position, and the second elastic member 412 is in a stretched state, so that the product a can be placed on the first supporting member 31 and the second supporting member 32 of the clamping position. When the product a needs to be clamped (as shown in fig. 5 and 6), the operator releases the operating member 23, and the operating member 23 automatically moves to the clamping position under the elastic force of the second elastic member 412, so that the movable clamping portion 22 and the fixed clamping portion 21 clamp the product a.

Further, the first linkage mechanism 41 further includes a first locking fitting 413 and a first locking member 414. The first locking engagement piece 413 is mounted on the first link block 410 to move along the first direction X with the first link block 410. The first locking member 414 is provided on the mounting bracket 10, and has a first locking portion 4141 (see fig. 8) and a second locking portion 4142 (see fig. 8).

When the operating member 23 is moved to the release position, the first locking member 414 is operable to cause the first locking portion 4141 to be in limit engagement with or disengaged from the first locking engagement 413; when the operating member 23 is moved to the release position, the first locking member 414 is operable to cause the second locking portion 4142 to be in limit engagement with or disengaged from the first locking engagement piece 413. In this way, the first locking portion 4141 of the first locking member 414 is in limit fit with the first locking mating piece 413 to limit the movement of the first linkage block 410 along the first direction X, so as to lock the operating member 23 at the releasing position. The second locking part 4142 of the first locking member 414 is in limit fit with the first locking mating part 413 to limit the movement of the first linkage block 410 along the first direction X, so as to lock the operating member 23 at the clamping position. That is, the first locking fitting piece 413 and the first locking piece 414 can lock the position of the operation piece 23, preventing the product a from falling.

Further, the first locking member 414 is rotatably connected to the mounting bracket 10, and the first locking member 414 is rotatably connected to the mounting bracket 10 and includes a first locking position and a first unlocking position. When the first locking member 414 rotates to the first locking position, the first locking mating piece 413 is in limit-limit engagement with the first locking portion 4141 or the second locking portion 4142 to prevent the first linkage block 410 from moving in the first direction X, thereby locking the operating member 23 in the clamping position or the releasing position. When the first locking member 414 rotates to the first unlocking position, the first locking fitting 413 is separated from the first locking portion 4141 or the second locking portion 4142, thereby releasing the restriction of the movement of the first link block 410 in the first direction X, so that the operating member 23 can move between the clamping position and the releasing position.

Further, the first locking mating piece 413 has a first head 4131, the first locking portion 4141 is a first limit groove formed on the first locking member 414, and the second locking portion 4142 is a second limit groove formed on the first locking member 414. When the first locking member 414 rotates to the first locking position, the first head 4131 is retained in the first retaining groove or the second retaining groove. When the first locking member 414 rotates to the first unlocking position, the first head 4131 exits the first limiting groove or the second limiting groove.

Further, the first linking mechanism 41 further includes a first torsion spring (not shown) assembled between the first locking member 414 and the mounting bracket 10 for providing a pre-tightening force to rotate the first locking member 414 from the first unlocking position to the first locking position. In this manner, when the operation member 23 needs to be unlocked, the operator presses the first locking member 414, so that the first locking member 414 rotates to the first unlocking position against the elastic force of the first torsion spring, thereby unlocking the operation member 23, so that the operation member 23 can move between the releasing position and the clamping position. When the operating member 23 needs to be locked, the operator releases the first locking member 414, so that the first locking member 414 automatically rotates to the first locking position under the action of the elastic force of the first torsion spring, and the first head 4131 is limited in the first limiting groove or the second limiting groove, thereby limiting the operating member 23 at the releasing position or the clamping position.

Referring to fig. 1 and fig. 2, in the embodiment of the present invention, the linkage assembly 40 includes a second linkage mechanism 42, and the second linkage mechanism 42 includes a second linkage block 420 and a second cam groove 421. The second linkage block 420 is movably connected to the mounting bracket 10 along the first direction X and is fixedly connected to the operating element 23, so that the second linkage block 420 can move along the first direction X along with the operating element 23. The second cam groove plate 421 is installed on the second linkage block 420, and is provided with a second cam groove B2. A second follower (not shown) is mounted on the second support member 32, and slidably engaged with the second cam groove B2. When the operating member 23 moves between the clamping position and the releasing position, the operating member 23 drives the second linkage block 420 and the second cam groove plate 421 to move along the first direction X, so that the second follower moves along the second cam groove B2 relative to the second cam groove plate 421, and further drives the second support member 32 to move closer to or away from the first support member 31. That is, the linear motion of the operating member 23 in the first direction X is converted into the linear motion of the second support member 32 in the second direction Y by the sliding fit of the second follower with the second cam groove B2. Alternatively, the second follower may be a rolling bearing, thereby reducing friction between the second follower and the second cam groove plate 421 so that the second follower can smoothly move along the second cam groove plate 421.

In an embodiment, the supporting assembly 30 further includes a third guiding rod (not shown) and a second mounting block 35, the third guiding rod is fixedly connected to the mounting bracket 10 and is parallel to the second direction Y. A second mounting block 35 is slidably connected to the third guide bar, and a second support 32 and a second follower are mounted on the second mounting block 35. When the second cam groove plate 421 moves along the first direction X along with the second linkage block 420, the second mounting block 35 is driven to slide along the third guide bar under the cooperation of the second follower and the second cam groove B2, and then the second supporting member 32 moves along with the second mounting block 35 to support or release the product a. It should be noted that one or more second supporting members 32 may be installed on the second installation block 35 as needed, as long as the product a can be stably supported, and the installation is not limited herein.

Specifically, in the embodiment, the second linking mechanism 42 further includes a third elastic element 422, one end of the third elastic element 422 is connected to the mounting bracket 10, and the other end is connected to the second linking block 420, so as to provide a pre-tightening force for driving the operating element 23 to move from the releasing position to the clamping position by the second linking block 420. Thus, when the operator needs to load the clamping position, the operator pushes the operating member 23 from the clamping position to the releasing position, and at this time, the third elastic member 422 is in a stretched state, so that the product a can be placed on the first supporting member 31 and the second supporting member 32 of the clamping position. When the product a needs to be clamped, the operator releases the operating member 23, and the operating member 23 automatically moves to the clamping position under the elastic force of the second elastic member 412, so that the movable clamping portion 22 and the fixed clamping portion 21 clamp the product a.

Further, the second linkage mechanism 42 further includes a second locking mating member 423 and a second locking member 424. The second locking mating member 423 is mounted on the second linkage block 420 to move along the first direction X with the second linkage block 420. The second lock 424 is provided on the mounting bracket 10, and has a third lock portion 4241 and a fourth lock portion 4242.

When the operating member 23 is moved to the release position, the second locking member 424 is operable to cause the third locking portion 4241 to be in limit engagement with or disengaged from the second locking engagement piece 423; when the operating member 23 is moved to the release position, the second locking member 424 is operable to cause the fourth locking portion 4242 to be in limit engagement with or disengaged from the second locking engagement member 423. In this way, the third locking portion 4241 of the second locking member 424 is in limit fit with the second locking mating member 423 to limit the movement of the second linkage block 420 along the first direction X, so as to lock the operating element 23 at the releasing position. The fourth locking part 4242 of the second locking member 424 is in limit fit with the second locking mating part 423 to limit the movement of the second linkage block 420 along the first direction X, so that the operating member 23 is locked at the clamping position. That is, the second locking fitting piece 423 and the second locking piece 424 enable locking of the position of the operation piece 23, preventing the product a from falling.

Further, the second locking member 424 is rotatably connected to the mounting bracket 10, and the second locking member 424 includes a second locking position and a second unlocking position during the rotation. When the second locking member 424 rotates to the second locking position, the second locking mating member 423 is in limit fit with the third locking part 4241 or the fourth locking part 4242 to prevent the second linkage block 420 from moving along the first direction X, so that the operating member 23 is locked at the clamping position or the releasing position. When the second locking member 424 rotates to the second unlocking position, the second locking mating member 423 is separated from the third locking part 4241 or the fourth locking part 4242, thereby releasing the restriction of the movement of the second interlocking block 420 in the first direction X, so that the operating member 23 can move between the clamping position and the releasing position.

Further, the second locking mating member 423 has a second head portion 42331, a third locking portion 4241 is a third limit groove formed on the second locking member 424, and a fourth locking portion 4242 is a fourth limit groove formed on the second locking member 424. When the second locking element 424 rotates to the second locking position, the second head 42331 is retained in the third retaining groove or the fourth retaining groove. When the second locking element 424 rotates to the second unlocking position, the second head 42331 exits the third or fourth limiting groove.

Further, the second linkage mechanism 42 further includes a second torsion spring (not shown), which is assembled between the second locking member 424 and the mounting bracket 10, and is used to provide a pre-tightening force for rotating the second locking member 424 from the second unlocking position to the second locking position. In this manner, when it is necessary to release the locking of the operating member 23, the operator presses the second locking member 424, so that the second locking member 424 rotates to the second unlocking position against the elastic force of the second torsion spring, thereby releasing the locking of the operating member 23, so that the operating member 23 can move between the releasing position and the clamping position. When the operating element 23 needs to be locked, the operator releases the second locking element 424, so that the second locking element 424 automatically rotates to the second locking position under the action of the elastic force of the second torsion spring, the second head 42331 is limited in the third limiting groove or the fourth limiting groove, and the operating element 23 is locked at the release position or the clamping position.

Further, the linkage assembly 40 further includes a pressing plate 43, and the pressing plate 43 is mounted on the first locking member 414 and the second locking member 424. When the pressing plate 43 is pressed, the first locking member 414 is driven to rotate to the first unlocking position, and the second locking member 424 is driven to rotate to the second unlocking position. When the pressing plate 43 is released, the first locking member 414 rotates to the first locking position by the first torsion spring, and the second locking member 424 rotates to the second locking position by the second torsion spring. The pressing operation of the pressing plate 43 is not limited to the pressing by the operator, and may be automated. For example, in one embodiment, the linking assembly 40 further includes a second driving member, which is installed on the mounting bracket 10 and is in driving connection with the pressing plate 43 to drive the pressing plate 43 to move, so as to drive the first locking member 414 to rotate between the first unlocking position and the first locking position, and drive the second locking member 424 to rotate between the second unlocking position and the second locking position. Alternatively, the second driver may be a cylinder or the like.

Further, the linkage assembly 40 further includes a first handle 11 and a second handle 12, the first handle 11 and the second handle 12 are fixedly connected to both ends of the mounting bracket 10 in the first direction X, and the operating member 23 is disposed near the first handle 11 and the pressing plate 43 is disposed near the second handle 12. Therefore, an operator can hold the first handle 11 and the second handle 12 by hands, and conveniently operate the operating piece 23 and the pressing plate 43, so that the product A can be clamped.

In the embodiment, the detecting jig further includes a pressing assembly 50, and the pressing assembly 50 includes a supporting plate 51, a pressing block 52 and a cam block 53. The support plate 51 is mounted to the mounting bracket 10 for supporting the flexible circuit board a of the product a at the clamping position. The pressing piece 52 is rotatably coupled to the mounting bracket 10 and includes a first position (see fig. 1) to press the flexible circuit board a and a second position (see fig. 4) to release the flexible circuit board a during the rotation.

The cam block 53 is connected with the second linkage block 420 and is in transmission fit with the pressing block 52. When the operating member 23 moves to the clamping position, the cam block 53 moves along with the second linkage block 420, and drives the pressing block 52 to rotate to the first position. When the operating member 23 moves to the release position, the cam block 53 moves along with the second linkage block 420, and drives the pressing block 52 to rotate to the second position. Thus, when the operating member 23 is moved to the release position, the cam block 53 drives the pressing block 52 to rotate to the second position, so that the flexible electric control board on the product a is located on the supporting plate 51 when the product a is placed on the first supporting member 31 and the second supporting member 32 in the clamping position. When the operating member 23 is moved to the clamping position, the cam block 53 drives the pressing piece 52 to rotate to the first position, so that the pressing piece 52 presses the flexible circuit board a on the product a against the support plate 51.

Further, the pressing assembly 50 further includes a magnetic member (not shown) disposed on the mounting bracket 10 or the supporting plate 51, and the magnetic member is used for fixing the pressing block 52 at the first position in a suction manner, so that the pressing block 52 presses the flexible circuit board a of the product a on the supporting plate 51. Alternatively, the magnetically attractive element may be a magnet.

It should be noted that a connector such as a probe may be further disposed on the supporting plate 51 for electrically connecting with the flexible circuit board on the supporting plate 51 to detect the product a.

Then, the operator pulls the operating piece 23 leftward to the release position with his left hand, so that the movable clamp portion 22 moves leftward. Meanwhile, the first linkage block 410 drives the first cam slot plate 411 to move leftward (the second elastic element 412 is stretched), so that the first follower 34 moves along the first cam slot B1 relative to the first cam slot plate 411, and the second linkage block 420 drives the second cam slot plate 421 to move leftward (the third elastic element 422 is stretched), so that the second follower moves along the second cam slot B2 relative to the second cam slot plate 421, and further drives the first supporting element 31 and the second supporting element 32 to approach each other and extend into the clamping position. Meanwhile, the cam block 53 moves leftward along with the second linkage block 420, thereby driving the pressing block 52 to rotate upward to the second position.

Then, the operator releases the pressing plate 43 with the right hand (both the first locking member 414 and the second locking member 424 are rotated downward) so that the first head 4131 is located in the first locking groove of the first locking member 414 and the first head 4131 is located in the third locking groove of the second locking member 424 to lock the operating member 23 in the release position. The operator places the product a on the first support 31 and the second support 32 of the gripping position.

Then, the right hand of the operator presses the pressing plate 43, and the left hand releases the operating member 23, so that the operating member 23 automatically moves to the right to the clamping position under the action of the second elastic member 412 and the third elastic member 422, and the movable clamping part 22 and the fixed clamping part 21 clamp the product a. Meanwhile, the first linkage block 410 moves rightward, so that the first follower 34 moves along the first cam groove B1 relative to the first cam groove plate 411, and the second linkage block 420 moves rightward, so that the second follower moves along the second cam groove B2 relative to the second cam groove plate 421, thereby moving the first support 31 and the second support 32 away from each other, and releasing the support of the product a. Meanwhile, the second linkage block 420 drives the cam block 53 to move rightwards, so that the pressing block 52 rotates to the first position under the adsorption action of the magnetic attraction piece, that is, the pressing block 52 presses the flexible circuit board a of the product a on the supporting plate 51.

Finally, the operator releases the pressing plate 43, so that the first locking member 414 rotates to the first locking position, the second locking member 424 rotates to the second locking position, the first head portion 4131 is located in the second locking groove of the first locking member 414, and the second head portion 42331 is located in the fourth locking groove of the second locking member 424, so as to lock the operating member 23 in the clamping position, and prevent the product a from falling.
