The groove 3 of the y-shaped arm 10 is riveted with one end of a bayonet 7 with a round hole, which is provided with an elastic sheet 6, and the bayonet 7 can rotate around the rivet (figure 2). The groove 2 is a circular groove, a thread structure is arranged at the position of a groove opening, a spring and the ejector rod 8 are sequentially placed into the groove opening and then screwed into the threaded sleeve 9 to fix the ejector rod 8, and the ejector rod 8 can move due to the spring (figure 1).
The r-shaped arm 2 (figure 3) is complex in structure and can be used as a bearing component and also provide mounting positions for a plurality of structural components. The R-shaped force arm 2 is provided with a rectangular groove III and a circular groove IV from top to bottom in sequence close to the upper end, the other side corresponding to the circular groove IV is provided with a rectangular groove II, two vertical surfaces of a working surface where the circular groove IV is located are respectively provided with a long groove I and a rectangular groove V, the long groove I starts from the uppermost end of the R-shaped force arm 2 and does not penetrate through the upper end to the vicinity of the bottom end, the rectangular groove V corresponds to and is communicated with the long groove I, and the inside of the long groove I is provided with a groove VI.
The first elongated slot is provided with a motor, a gear set, a screw rod 3, a stop block 4, a stop plate 5 and two spring mounting positions, the motor is in threaded connection with the gear set, the screw rod 3 and the gear set are in a gear-thread transmission structure, the stop block 4 is a cuboid, a threaded hole is formed in the center of the cuboid, and the screw rod 3 is screwed in. Under the action of the motor, the screw rod 3 rotates, the first long groove prevents the stop block 4 from rotating along with the first long groove, and the stop block 4 moves along the first long groove. The stop plate 5 is similar to a rectangular thin plate, after the spring is arranged in the groove six, the stop plate is riveted in the long groove one, and one end of the stop plate 5 is positioned above the groove six and can move around the rivet to realize wane movement; after the parts in the long groove I are installed, covering an aluminum sheet above the working surface where the long groove I is located, and fixing the aluminum sheet through a threaded structure;

With reference to fig. 5, the main operation of the release lock is as follows:
1) the two clamping plates of the separating lock are connected with the parachute through bolts, and the clamping pin is connected with the air-drop piece.
2) Locking state: when the two force arms are clamped, the ejector rod is compressed, the bayonet lock riveted with the elastic sheet is inserted into a clamping groove (groove five) corresponding to the r-shaped force arm, tension is applied to two ends of the break-away lock under the condition that the two force arms are clamped, the spring and the elastic sheet below the bayonet lock are compressed simultaneously, the stop plate is pressed downwards and clamped into a step on the bayonet lock, then the boat-shaped switch is pressed down, the stop block is pushed into the lower portion of the stop plate by the motor until the circuit-breaking switch (figure 4) is triggered, the motor stops working, the circuit-breaking pin is inserted into the break-away switch, the boat-shaped switch is shifted to the other end, and the break-away lock is in a locking state at the moment.
3) An air-drop state: after the airdrop part leaves the airplane, the parachute is opened while the breaking pin is pulled out, the motor rotates reversely, the stop block is moved out of the lower portion of the stop plate, the stop plate tilts under the action of the spring, at the moment, the stop plate does not contact with the step at the end of the bayonet lock any more, and locking is released. When the stop block moves upwards to a certain position, the circuit breaking switch is triggered (fig. 4, the two ends of the fixed block are adhered with insulating bulges, and the metal sheet can be pushed open during movement to realize the circuit breaking effect), so that the motor stops working. After the parachute is completely opened, the clamping pin compresses the spring below the clamping pin under the action of the tensile force of the air-drop piece. After the air-drop part lands, the bayonet lock is bounced under the action of the ejector rod. The two force arms are flicked to separate the air-drop part from the parachute, and the unlocking is completed.
The invention has good test process after nearly 30 times of tests on the ground, smooth unlocking at the moment when the tension at two ends of the unlocking disappears, and no faults of unsmooth actuation, clamping stagnation and the like, thereby basically achieving the expected effect.
The invention can change the time of opening the air fuse by replacing the gear set connected with the motor so as to adapt to different small part air-drop conditions.
