[0020] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0021] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the application have the same meaning as that generally understood by ordinary skilled persons in the technical field to which the application belongs.

[0022] In the utility model, unless otherwise stated, the orientation such as "upper", "lower" is generally for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction. Similarly, for the convenience of understanding and description, "left", "right" is generally for the left and right shown in the drawing, and "inner", "outer" refers to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the utility model.

[0023] AsFigures 1-2 As shown, the application provides a fastener screening device, which comprises a base 1, the upper side of the base 1 is fixed with a support table 11, and the upper side of the support table 11 is provided with a toothed plate 12. The two sides of the support table 11 are both provided with a movable table 2, and the upper side of the movable table 2 is provided with a plurality of teeth 21, and one side of the teeth 21 extends to the upper side of the support table 11.

[0024] The two ends of the two sides of the support table 11 are both fixed with a guide shaft 13, and the guide shaft 13 penetrates one movable table 2. A rotating shaft 14 is rotatably arranged in the support table 11, the two ends of the rotating shaft 14 respectively penetrate one movable table 2, the two ends of the rotating shaft 14 are respectively threadedly connected with one movable table 2, and the thread directions of the two ends of the rotating shaft 14 are opposite.

[0025] The teeth 21 are all provided with a plurality of clamping grooves 22, and the clamping grooves 22 are clamped with a baffle 3. One side of one tooth 21 is provided with a positioning hole 23, the baffle 3 is provided with a through hole 31 corresponding in position to the positioning hole 23, a clamping pin 32 is arranged in the positioning hole 23, and the clamping pin 32 penetrates the through hole 31. In the embodiment, the clamping pin 32 is a bolt, and the clamping pin 32 is threadedly connected with the positioning hole 23.

[0026] In the invention patent with the publication number CN118321171B, the structure of the movable toothed plate 12 and the method of screening bolts and nuts by cooperation between the toothed plate 12 and the teeth 21 have been given, and the structure is not improved in the case, so the structure is not introduced.

[0027] The guide shaft 13 is used for limiting the movement direction of the movable table 2, so that the movable table 2 can only move in the direction of approaching or moving away from the support table 11, thereby avoiding that the teeth 21 are inclined or deviated by the movable table 2.

[0028] One end of the rotating shaft 14 is provided with a handle 15, and the staff can rotate the rotating shaft 14 through the handle 15, so that the movable table 2 drives the teeth 21 to approach or move away from the support table 11 through the threaded connection between the rotating shaft 14 and the movable table 2.

[0029] Since the thread directions of the two ends of the rotating shaft 14 are opposite, the two movable tables 2 will simultaneously approach or move away from the support table 11, on the one hand, the distance between the two teeth 21 on the two sides can be adjusted to adapt to nuts of different sizes, so that the distance between the teeth 21 is not too small to screen out nuts, or the distance between the teeth 21 is too large to screen out short bolts. On the other hand, the toothed plate 12 can be kept in the middle of the two teeth 21, so that the toothed plate 12 can lift the middle position of the bolt to reduce the sliding of the bolt.

[0030] After the pin 32 is removed, the baffle 3 can be taken out from the slot 22, and then inserted into a new slot 22, and the pin 32 is installed into the positioning hole 23 and passes through the through hole 31, so that the baffle 3 is replaced and fixed, and the distance between the two baffles 3 is adjusted, so that the fastener screening device can screen longer bolts.

[0031] Therefore, the fastener screening device can be adjusted to adapt to bolts of different lengths and nuts of different sizes.
