When the classifying and discharging mechanism is used, nuts or accessories of different models are sleeved on the vertical rod, so that the corresponding models can be directly selected in the matching process in the later stage. However, given the fixed distance between the vertical rods, there is a certain spatial limitation for the gripping jaws, and the nuts or fittings at the bottom of the vertical rods are less easily gripped. The inventors therefore made the following modifications: as shown in fig. 1 to 2, the tick magazine includes: the stand 8 is positioned on one side of the base 1; a second rotating mechanism provided in the stand 8; the second rotating disk 2 is positioned above the stand 8, and the second rotating disk 2 is in transmission connection with the second rotating mechanism; a plurality of material storage cylinders 10; the second rotating disk 2 is fixed at the edge of the second rotating disk at equal distance; the top end of the storage barrel 10 is of an open structure, and a conduction groove 11 is formed in the inner side wall of the storage barrel 10 along the length direction of the storage barrel; a plurality of mounting plates 12; the mounting plate 12 is correspondingly fixed on the lower surface of the second rotating disc 2 and is positioned at the inner side of the storage cylinder 10; a transversely arranged top plate 13 is movably clamped on the outer side wall of the mounting plate 12, and the movable end of the top plate 13 penetrates through the conduction groove 11 and is positioned in the storage barrel 10; the fixed end of the top plate 13 is fixedly connected with the bottom of the mounting plate 12 through a compression spring; when the storage barrel 10 is filled with materials, the top plate 13 is positioned at the bottom of the storage barrel 10, and the compression spring is in a compressed state; when only one material is in the storage cylinder 10, the compression spring is in a normal state, the top plate 13 is located at the top of the storage cylinder 10, and the material is exposed above the storage cylinder 10.

The distance between the two guide strips 304 is greater than the outer diameter of the bolt shank 6 and less than the inner diameter of the bolt head 7.
The two guide strips 304 are used for realizing the orderly and vertical arrangement of the bolts and transferring the bolts into the placing cavity, the head 7 of the bolt positioned in the placing cavity is positioned at the bottom end, and the working principle is as follows: the bolts are orderly arranged to the outlet under the action of the vibrating disk, the bolts are transversely arranged at the moment, and the bolts continuously push the bolts in front forwards. When the first bolt is pushed between the guide strips 304, the bolt is suspended between the two guide strips 304, i.e. the head 7 is at the top, as the distance between the two guide strips 304 is larger than the outer diameter of the bolt shank 6 and smaller than the inner diameter of the bolt head 7, and the bolt shank 6 falls from the gap between the two guide strips 304. The vertical arrangement of the bolts is realized.
However, in this embodiment, the nut and other fittings are later fitted directly onto the threaded rod 6, so that when the bolt reaches the placing cavity, the head 7 of the bolt is required to be at the bottom end.
Therefore, in order to achieve the above function, the inventor makes the following limitations on the guide bar 304: the guide bar 304 includes: a connecting portion 3041, a diverting portion 3042, a guide portion 3043, and a supporting portion 3046. The connecting portion 3041 and the guiding portion 3043 are horizontally disposed, the upper surface of the connecting portion 3041 is flush with the bottom of the outlet, the end of the guiding portion 3043 extends above the placing cavity, the reversing portion 3042 is arc-shaped and is connected between the connecting portion 3041 and the guiding portion 3043; the supporting portion 3046 is respectively disposed at the inner wall of the reversing portion 3042 and below the guiding portion 3043, and a gap is left between the supporting portion 3046 and the reversing portion 3042 and the guiding portion 3043; the end of the support 3046 extends to the edge of the placing cavity, so that the bolt directly falls into the placing cavity when falling.

And the support 3046 is to prevent the bolt from falling out in advance without being restricted by the guide bar 304.
In order to accelerate the movement of the bolt at the connecting portion 3041 and provide enough space for the bolt which needs to be changed from a horizontal direction to a vertical direction, the inventor arranges a conveyer belt 3044 between the placing frame 302 and the guide bar 304, wherein the conveyer belt 3044 is in transmission connection with a roller 3045, and the roller 3045 is in transmission connection with a driving motor.
The nut is screwed on the screw 6 of the bolt, so that the nut has a function of rotating downwards in addition to a function of clamping. Therefore, in this embodiment, the nut feeding mechanism 4 includes: a second vibration plate, and a clamp assembly disposed between the second vibration plate and the rotation plate 2.
