When the sliding block 42 moves, it can guide the rotating arm 41 to move along a predetermined trajectory. When the rotating arm 41 moves, it drives the rotating shaft 2 and the clamping block 3 to flip to achieve the clamping or loosening of the spring 5.

[0040] Optionally, the rotating arm 41 is connected to the rotating shaft 2 through a transmission component. When the rotating arm 41 moves, the rotating shaft 2 is driven to rotate, and when the rotating shaft 2 rotates, the clamping block 3 is driven to flip.

[0041] Optionally, two slots 421 are provided on the sliding block 42, one end of the rotating arm 41 is transmission-connected to the rotating shaft 2, and the other end is slidably provided in the corresponding slot 421.

The rotating arm 41 can be slidably connected to the slide groove through a sliding component; the connecting block 13 can also be slidably connected to the slide groove 422 through a sliding component. Such as a roller, a slider, etc.

[0045] As an implementation scenario, in this scenario, the driving member 43 includes a pushing shaft 431, a first elastic member 432, a locking shaft 433, and a second elastic member 434. The pushing shaft 431 is used to drive the sliding block 42 to move, and the locking shaft 433 is used to lock or unlock the sliding block 42.

[0046] Optionally, the sliding block 42 includes a first connecting section 42a, a second connecting section 42b and a third connecting section 42c. Two grooves 421 are provided on the first connecting section 42a, and the slide groove 422 is provided between the two grooves 421. One end of the second connecting section 42b is connected to one end of the first connecting section 42a, and the second connecting section 42b is perpendicular to the first connecting section 42a to form an "L"-shaped structure. One end of the third connecting section 42c is connected to one end of the second connecting section 42b, and the third connecting section 42c and the second connecting section 42b form an "L"-shaped structure. The pushing shaft 431 acts on the side wall of the second connecting section 42b. The locking shaft 433 acts on the third connecting section 42c to lock or unlock the sliding block 42. When the sliding block 42 needs to be locked, the locking shaft 433 cooperates with the third connecting section 42c to prevent the sliding block 42 from moving. When unlocking is required, the locking shaft 433 moves and disengages from the matching position of the third connecting section 42c.

[0047] Optionally, the locking shaft 433 is mounted on the bracket through two first mounting seats 435, the pushing shaft 431 is arranged on one side of the second connecting section 42b through the second mounting seat 436, the second mounting seat 436 can be connected to the bracket or the first mounting seat 435, the second mounting seat 436 is arranged opposite to the second connecting section 42b, the pushing shaft 431 is slidably matched with the second mounting seat 436, one end of which is connected to the side wall of the second connecting section 42b, and the pushing shaft 431 located between the second connecting section 42b and the second mounting seat 436 is provided with a first elastic member 432. The locking shaft 433 is provided with a second elastic member 434.

[0048] Optionally, a matching groove 423 matching with the locking shaft 433 is provided on the third connecting section 42c.

[0049] Optionally, the first elastic member 432 is a return spring, and the driving shaft 431 is a return spring shaft.

[0050] Optionally, the second elastic member 434 is a return spring. During the locking process, the return spring is in a pre-compressed state. In the locked state, the elastic force of the return spring is limited by the locking shaft and does not cause the sliding block to move. When unlocking, the return spring releases the elastic force. When in use, the locking shaft 433 and / or the driving shaft 431 can be moved by the operating mechanism.

[0051] When in use, the bullet 5 is held tightly by the four clamping blocks 3 fixed on the rotating shaft 2 on both sides of the bullet tray 11, and the rotating shaft 2 is driven to rotate and locked by the rotating arm 41, the sliding block 42, the locking shaft 433, the first elastic member 432, the second elastic member 434, etc. so that the four clamping blocks 3 are in a state of holding the bullet 5. When the bullet tray 11 is in the bullet feeding state, the locking shaft 433 is unlocked, the first elastic member 432 acts on the pushing shaft 431 to push the sliding block 42 to slide, the sliding block 42 causes the rotating arm 41 to rotate, and the rotating arm 41 drives the rotating shaft 2 and the four clamping blocks 3 to flip, and releases the tight hold on the bullet 5.

[0052] As another implementation scenario, in this scenario, the driving member 43 can also directly adopt an electric telescopic rod or a cylinder, etc. Its movable end is connected to the sliding block 42, and drives the sliding block 42 to move left or right when extended or retracted. When in use, when it is necessary to hold the spring 5 tightly, the driving member 43 drives the sliding block 42 to move to one end and keep it still, so that the sliding block 42 drives the rotating arm 41 to rotate clockwise to make the clamping block 3 hold the spring 5 tightly; when it is necessary to release the clamping, the driving member drives the sliding block 42 to move to the other end, so that the sliding block 42 drives the rotating arm 41 to rotate counterclockwise to make the clamping block 3 release the spring 5.

[0053] Parts not described in detail in this embodiment are well-known techniques in the art.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
