A turntable 507 and a gear 513 are rotatably connected to the inner side of the support frame 506. 7. The turntable 507 is located on the outer side, and a clamping member is fixedly connected to its outer surface. A first rack 509 for meshing with the gear 513 is provided on the outer periphery of the turntable 507, and a second rack 514 for meshing with the gear 513 is provided on the inner wall of the opening 504. An active space 516 is provided in the middle of the support block 501. A push rod 517 is slidably passed through the side of the support block 501 away from the connecting plate 521, and one end of the push rod 517 extends into the active space 516 and is connected to a pull rope 518. The pull rope 518 passes radially through the push rod 517, and the two ends of the pull rope 518 are symmetrically fixed with first pins 5 for engaging with the adjacent movable rod 505. 20. When the first pin 520 engages with the movable rod 505, the two clamping parts are in a fully open state; the support block 501 has a first storage groove 531, the first pin 520 is located in the first storage groove 531, and the bottom of the first pin 520 is connected to the bottom of the first storage groove 531 through the first compression spring 519; a first channel for the pull rope 518 to pass through is provided between the first storage groove 531 and the movable space 516, one end of the first channel is connected to the first storage groove 531, and the other end is connected to the movable space 516; the connecting plate 521 is connected to the support block 501 through the second compression spring 522, and the connecting plate 521 and the movable rod 505 are connected to the support block 501. A first connecting rope 523 passes through the support frame 506 and the first connecting rope 523. The two ends of the first connecting rope 523 are symmetrically fixed with second pins 526. The second pins 526 are connected to the inner wall of the support frame 506 through a third compression spring 525.

A turntable 507 and a gear 513 are rotatably connected to the inner side of the support frame 506. 7. The turntable 507 is located on the outer side, and a clamping member is fixedly connected to its outer surface. A first rack 509 for meshing with the gear 513 is provided on the outer periphery of the turntable 507, and a second rack 514 for meshing with the gear 513 is provided on the inner wall of the opening 504. An active space 516 is provided in the middle of the support block 501. A push rod 517 is slidably passed through the side of the support block 501 away from the connecting plate 521, and one end of the push rod 517 extends into the active space 516 and is connected to a pull rope 518. The pull rope 518 passes radially through the push rod 517, and the two ends of the pull rope 518 are symmetrically fixed with first pins 5 for engaging with the adjacent movable rod 505. 20. When the first pin 520 engages with the movable rod 505, the two clamping parts are in a fully open state; the support block 501 has a first storage groove 531, the first pin 520 is located in the first storage groove 531, and the bottom of the first pin 520 is connected to the bottom of the first storage groove 531 through the first compression spring 519; a first channel for the pull rope 518 to pass through is provided between the first storage groove 531 and the movable space 516, one end of the first channel is connected to the first storage groove 531, and the other end is connected to the movable space 516; the connecting plate 521 is connected to the support block 501 through the second compression spring 522, and the connecting plate 521 and the movable rod 505 are connected to the support block 501. A first connecting rope 523 passes through the support frame 506 and the first connecting rope 523. The two ends of the first connecting rope 523 are symmetrically fixed with second pins 526. The second pins 526 are connected to the inner wall of the support frame 506 through a third compression spring 525. A first slot 510 is provided on the outer circumference of the turntable 507 for engaging with the second pins 526. When the two clamping parts are in the clamping state, the second pins 526 engage with the first slot 510. An unlocking block 524 is provided transversely on the connecting plate 521 for pushing the first connecting rope 523 to compress the second pins 526 at both ends of the third compression spring 525. The unlocking block 524 is slidably connected to the connecting plate 521.

[0070] A second storage groove 527 is provided on the side of the support frame 506 near the inner wall of the opening 504. A third pin 529 is provided in the second storage groove 527. A second slot 515 is provided on the inner wall of the opening 504 for engaging with the third pin 529. The bottom of the third pin 529 is connected to the bottom of the second storage groove 527 through a fourth compression spring 528. The third pin 529 is connected to the first connecting rope 523 through a second connecting rope 530. A second channel is provided at the bottom of the second storage groove 527 for the second connecting rope 530 to pass through.

[0071] Understandably, to prevent the movable lever 505 from moving during clamping, the third pin 529 is inserted into the second slot 515 to prevent the movable lever 505 from accidentally releasing. When unlocking is required, the user holds the connecting plate 521 and pushes the unlocking block 524 relative to it. The unlocking block 524 pushes the first connecting rope 523, causing the second pins 526 connected to both ends to leave the first slot 510 and compress the third compression spring 525, thereby releasing the locked state of the turntable 507. At the same time, the first connecting rope 523 will pull the second connecting rope 530, causing the third pin 529 to leave the second slot 515. At this time, pushing the connecting plate 521 will open the two clamping parts, making it convenient to use.

[0072] There can be multiple second slots 515, which are distributed along the sliding direction of the movable rod 505. Specifically, the top of the third pin 529 is provided with an inclined surface on the side facing the connecting plate 521, so that after the third pin 529 is engaged with the second slot 515, the movable rod 505 can only move to the left and cannot move to the right, which can effectively prevent the clamping from loosening and make the clamping member clamp the power component more firmly.

[0073] The movable rod 505 has a corresponding third slot 532 for engaging with the first pin 520. Specifically, the top of the first pin 520 has a bevel on the side facing the connecting plate 521.

[0074] The turntable 507 is connected to the support frame 506 via a spiral spring 508.

[0075] The clamping components include a rotating frame 511 and a clamping plate 512 fixed to the inner wall of the rotating frame 511.

[0076] It also includes: two slide rails 1 symmetrically arranged at the top and bottom of the support block 501; sliders 502 for sliding cooperation with the adjacent slide rails 1 are provided at the top and bottom of the support block 501, and fixing brackets 2 are symmetrically fixed on both sides of one end face of the slide rail 1.

[0077] A threaded rod 503 is fixed to one side of the sliding block 502, a slide way 4 matched with the threaded rod 503 is correspondingly formed on the sliding rail 1, the threaded rod 503 penetrates through the slide way 4 and is connected with a nut 6 in a threaded manner, and through holes for the sliding block 502 to enter and exit are symmetrically formed on two sides of the other end face of the sliding rail 1.

[0078] Specifically, the unlocking block 524 is of a soil-shaped structure.

[0079] The second compression spring 522 is located between the connecting plate 521 and the support block 501, and the second compression spring 522 is sleeved on the movable rod 505.

[0080] In specific implementation, firstly, the electric element is abutted against the push rod 517 and the electric element and the push rod 517 are pressed integrally,

[0081] at this time, the first plug pin 520 leaves the third insertion slot 532, the movable rod 505 automatically springs open under the action of the second compression spring 522 and drives the support frame 506 to move, since the gear 513 and the turntable 507 are both rotationally connected to the support frame 506, the gear 513 and the turntable 507 move leftwards together along with the support frame 506, in the moving process, the gear 513 rotates under the action of the second rack 514, and drives the turntable 507 and the clamping member fixedly connected with the turntable 507 to rotate 90 degrees clockwise as a whole, so that the rotating frame 511 rotates to a horizontal state, and the electric element is clamped by the clamping plates 512 fixed on the inner wall of the rotating frame 511, at this time, the second plug pin 526 automatically springs into the first insertion slot 510 under the action of the third compression spring 525, so as to lock the turntable 507, meanwhile, the first connecting rope 523 is tensioned, and the unlocking block 524 is sprung open; in the process that the movable rod 505 moves leftwards, the third plug pin 529 can be automatically clamped into the second insertion slot 515 under the action of the fourth compression spring 528, so that the movable rod 505 can only move leftwards and cannot move rightwards, thereby effectively avoiding the situation of clamping looseness and enabling the clamping member to clamp the electric element more firmly; the support block 501 can slide in the sliding rail 1 through the sliding block 502, the sliding block 502 can be abutted and fixed by tightening the nut 6, and then the support block 501 is positioned; when unlocking the electric element, hold the connecting plate 521 first and press the unlocking block 524, the unlocking block 524 pushes the first connecting rope 523 to make the second plug pin 526 connected with both ends of the first connecting rope leave the first insertion slot 510 and compress the third compression spring 525, so as to release the locking state of the turntable 507, meanwhile, the first connecting rope 523 drives the third plug pin 529 to leave the second insertion slot 515 through the second connecting rope 530, so as to unlock the movable rod 505, then push the connecting plate 521, the movable rod 505, the support frame 506, the turntable 507, the gear 513 and the clamping member integrally rightwards to drive the turntable 507 and the clamping member to rotate counterclockwise integrally, so that the two clamping members are opened, and then the electric element is released.
