The movement process of the ratchet mechanism 3 is as follows:

the first step is as follows: when the front end of the push rod ratchet body 311 (the front end refers to the end of the push rod ratchet body 311 away from the ratchet 312, and the end of the ratchet 312 is the rear end, and so on, the following description is repeated), the push rod ratchet 31 can move backward in the first direction, and when the tooth portion 3122 on the ratchet 312 abuts against the claw portion side wall of the pawl 321, the rotating ratchet 32 moves backward to the bottom tip a (critical point) of the guide rail 342 as a whole, and abuts against the push rod 33, and the push rod 33 moves backward to act on the first elastic member 35, so that the first elastic member 35 is compressed.

The second step is that: the compression force of the first elastic member 35 is reacted to the rotating ratchet wheel 32 through the push rod 33, so that the rotating ratchet wheel 32 rotates in a single direction, and further the bottom tip a of the guide rail 342 abuts against the second groove portion 3212 of the pawl 321, an interaction force exists between the rotating ratchet wheel 32 and the guide rail 342, when the rotating ratchet wheel 32 and the guide rail 342 continue to move and pass the critical point, the rotating ratchet wheel 32 continues to rotate in a single direction, and finally the pawl 321 of the rotating ratchet wheel 32 is clamped at the guide rail 342, at this time, the top block 333 on the push rod 33 is located at the front end of the limiting opening 343, the lock rod mechanism 4 falls down, the card slot 15 is in an unlocked state, and meanwhile, the push rod ratchet wheel 31 rebounds forward under the action of the first elastic member 35.

The third step: the push rod ratchet 31 continues to spring back to the front home position in preparation for the next press.

The fourth step: press again push rod ratchet 31, at this moment, under the elastic action of first elastomeric element 35, rotatory ratchet 32 continues along former direction unidirectional rotation motion for first track groove 313 with second track groove 322 intercommunication, the motion stroke of guide rail 342 increases, works as the most advanced a in bottom of guide rail 342 supports when the bottom of second track groove 322, push rod 33 drives kicking block 333 moves backward to the rearmost end of spacing mouth 343, with locking lever mechanism 4 jack-up, pins draw-in groove 15.

The fifth step: the push rod ratchet 31 continues to spring back to the front home position in preparation for the next press.

Referring again to fig. 1, the locking lever mechanism 4 includes: an elevating rod 41, a locking member 42 provided on a side wall of the elevating rod 41, a second elastic member 45 provided at one end of the elevating rod 41, and a ball 43 provided at the other end of the elevating rod 41. Specifically, in this embodiment, a step 44 is disposed at a position of the lifting rod 41 corresponding to the second elastic component 45, the second elastic component 45 is sleeved on the step 44, and the second elastic component 45 is a spring. The ball 43 is embedded in the bottom of the lifting rod 41, and the ball 43 can easily interact with the top block 333 by rolling to jack up the lifting rod 41, and the ball 43 and the top block 333 interact easily and smoothly.

The locking member 42 includes: in this embodiment, the latching portion 422 can be stopped at an end surface of the card slot 15 from bottom to top, so that the carrier 2 can be locked and prevented from falling off after the carrier 2 is placed in the card slot 15, and when the carrier 2 needs to be taken or placed, the locking member 42 can be dropped downward to separate the latching portion 422 from the card slot 15 for unlocking.

In this embodiment, the magazine further includes a triggering system, the triggering system includes a sensor, a controller and the triggering mechanism, the sensor is specifically a position sensor, and the sensor may be disposed at a corresponding position of the magazine rack 1, for example, at a side of the slot 15. The inductor reaches trigger mechanism all with the controller is connected, through the inductor response the cartridge clip material frame 1 open and shut the state, give signal transmission the controller, the controller will control trigger mechanism action, further trigger ratchet 3 is followed the first direction motion, and then will locking lever mechanism 4 jack-up or fall down, the realization is right the locking or the unblock of cartridge clip material frame 1. The trigger mechanism can be arranged on a feeding machine or a blanking machine, specifically, in this embodiment, the trigger mechanism comprises a jacking cylinder and a pneumatic thimble connected with the jacking cylinder, the pneumatic thimble is used for contacting with the push rod ratchet wheel 31 and applying the pressing force to the ratchet mechanism 3 under the action of the jacking cylinder. The bottom of the cartridge clip material frame 1 is provided with a thimble hole 16, and the pneumatic thimble can contact with the end of the push rod ratchet wheel 31 on the ratchet mechanism 3 through the thimble hole 16, so as to apply the pressing force to the ratchet mechanism 3.
