The pawl release lever 5 is mounted on a second rotating shaft 11, and the safety linkage 3 is mounted on a third rotating shaft 12. The mechanical safety lever 2 is equipped with a mechanical safety lever U-shaped block 13, and the electric safety gear 1 is equipped with an electric safety gear boss 14. When locked, the electric safety gear boss 14 is engaged in the mechanical safety lever U-shaped block 13. The mechanical safety lever 2 is also equipped with a mechanical safety key slot 15, and the mechanical safety lever U-shaped block 13 is unlocked by inserting a key into the mechanical safety key slot 15. The electric double safety gear 27 is equipped with an electric double safety gear groove 16, and the upper end of the auxiliary release lever 30 is equipped with an auxiliary release lever groove 17. A slider 18 is installed in the electric double safety gear groove 16 and the auxiliary release lever groove 17. By sliding the slider 18 in the electric double safety gear groove 16 and the auxiliary release lever groove 17, the auxiliary release lever 30 and the second release lever 26 are linked. The mechanical safety lever 2 is provided with a mechanical safety lever inclined surface 19, and the electric double safety gear 27 is provided with a safety gear swing arm boss 20. The safety gear swing arm boss 20 moves on the mechanical safety lever inclined surface 19 as the electric double safety gear 27 rotates. A manual safety lever 21 is provided next to the electric safety gear 1. The manual safety lever 21 is provided on the fourth rotating shaft 22 and is set close to the electric safety gear 1.

[0024] like Figure 1-3 As shown, the principle of insurance is: the institution is in an uninsured state ( Figure 2The electric motor worm gear mechanism or mechanical safety lever 2 slides in the direction of arrow 1. The mechanical safety lever U-shaped block 13 pushes the electric safety gear boss 14, causing the electric safety gear 1 to rotate around the first rotating shaft 6 in accordance with arrow 3. The rotation of the electric safety gear 1 and the electric safety gear transmission rod 10 push the safety linkage locking hook 9. The safety linkage 3 rotates around its own third rotating shaft 12 in accordance with arrow 5. The safety linkage 3's own rotating shaft is fitted into the circular hole feature of the first release rod 4. The rotation of the safety linkage 3 causes the safety linkage boss 8 to disengage from the pawl release rod boss 7, achieving the engaged state and realizing the safety function.
[0025] The principle of insurance: The institution is in an insured state ( Figure 1 The electric motor worm gear mechanism or mechanical safety lever 2 slides in the direction of arrow 2. The mechanical safety lever U-shaped block 13 pushes the electric safety gear boss 14, causing the electric safety gear 1 to rotate around the first rotating shaft 6 in accordance with arrow 4. As the electric safety gear 1 rotates, the electric safety gear transmission rod 10 disengages from the safety link locking hook 9. Under the action of the return spring, the safety link 3 rotates around its own third rotating shaft 12 in accordance with arrow 6. The rotating shaft of the safety link 3 is fitted into the circular hole feature of the first release rod 4. The rotation of the safety link 3 causes the safety link boss 8 to engage with the pawl release rod boss 7, achieving the unlocked state and realizing the unlocking function.
[0026] like Figure 4-5 As shown, the electric double-insurance gear mechanism operates on the following principle: the mechanism is in the unlocked state ( Figure 5 The motor worm gear mechanism drives the electric double safety gear 27 to rotate around its own electric double safety gear shaft 28 in the direction of arrow 7. The slider 18 is placed in the electric double safety gear slide groove 16 and the auxiliary release rod slide groove 17. The electric double safety gear slide groove 16 drives the slider 18 to slide in the auxiliary release rod slide groove 17 in the direction of arrow 8, so that the slider 18 is misaligned with the release rod limit platform 25, thereby achieving the safety function.
[0027] The principle of insurance: The institution is in an insured state ( Figure 4 The motor worm gear mechanism drives the electric double safety gear 27 to rotate around its own electric double safety gear shaft 28 in the direction of arrow 9. The slider 18 is placed in the electric double safety gear slide groove 16 and the auxiliary release rod slide groove 17. The electric double safety gear slide groove 16 drives the slider 18 to slide in the auxiliary release rod slide groove 17 in the direction of arrow 10, so that the slider 18 coincides with the release rod limit platform 25, thereby achieving the function of releasing the safety.
[0028] like Figure 6-8 As shown, the mechanical double-insurance mechanism operates in the following manner: the mechanism is in the upper insured state ( Figure 6The manual safety lever 21 rotates around its fourth pivot 22 in the direction of arrow 13. The manual safety lever protrusion 24 pushes the fan-shaped groove 23 to make the electric safety gear 1 rotate around its first pivot 6 in the direction of arrow 14. The electric safety gear 1 rotates and the electric safety gear transmission rod 10 disengages from the safety link locking hook 9. The safety link 3 rotates around its third pivot 12 in the direction of arrow 6 under the action of the return spring. The pivot of the safety link 3 is assembled in the round hole feature of the first release lever 4. The rotation of the safety linkage 3 causes the safety linkage boss 8 to engage with the pawl release lever boss 7, thus releasing the safety. Simultaneously, the mechanical safety lever 2, driven by the electric safety gear boss 8, moves in the direction of releasing the safety. The inclined surface 19 of the mechanical safety lever pushes the safety gear swing arm boss 20, causing it to rotate around the electric double safety gear shaft 28 in the direction of arrow 9. The slider 18 is placed in the electric double safety gear slide groove 16 and the auxiliary release lever slide groove 17. The electric double safety gear slide groove 16 drives the slider 18 to slide in the auxiliary release lever slide groove 17 in the direction of arrow 14, so that the slider 18 coincides with the release lever limit platform 25, thereby releasing the safety.
