Abstract
The utility model relates to a screw disc, which belongs to the technical field of screw installation assistant tool, which comprises a disc body, wherein the upper surface of the disc body is formed with a groove, the bottom portion of the groove is equipped with a plurality of screw holes, the screw holes comprise taper holes on the upper segment and equal diameter holes on the lower segment, the taper holes are of a shape with big upper end and small lower end, and the diameter of the lower end of the taper hole is equal to the diameter of the equal diameter hole, is smaller than the diameter of a screw cap portion, and is bigger than the outer diameter of a screw thread segment. The screw disc is convenient for a cross opening knife head to match with a cross groove of the screw cap portion, is favorable to increase the work efficiency of an installation screw of the cross opening knife, and solves the problem in the prior art that because the screw is not convenient to be absorbed through using the installment screw of the cross opening knife, the work efficiency is lower and the like.
Description
Technical field
The utility model relates to a kind of screw dish, belongs to the technical field of screw mounting auxiliary.
Technical background
In the prior art, the cross that all adopts head to have magnetic usually when mounting screw is operated on and is operated.Cross is operated on and cross must be operated on head be engaged in the cross recess of screw cap portion when mounting screw, but usually screw always is deposited in the screw box mussily.Therefore, head operated in cross just needs manual screw is grasped when drawing screw, then the cap portion of screw being coupled to cross operates on the head, or earlier operate on head and draw a screw with cross, and then manual adjustment is operated on the cap portion cross recess of screw and cross on head and is cooperated, no matter adopt above-mentioned the sort of mode, all will have influence on and adopt cross to operate on the operating efficiency of mounting screw, cause the lower problem of operating efficiency.
Summary of the invention
The utility model purpose be to provide a kind of be convenient to cross operate on the head cooperate with the cross recess of screw cap portion, be beneficial to and improve cross and operate on the screw dish of operating efficiency of mounting screw, problems such as the employing cross that has solved the prior art existence is operated on mounting screw owing to drawing comparatively inconvenience of screw, and operating efficiency is lower.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises disk body, described disk body upper surface forms a groove, bottom portion of groove is provided with some screw holes, described screw hole is made of the bellmouth of epimere and the isometrical hole of hypomere, described bellmouth is small top and big bottom, the lower end diameter of bellmouth and the equal diameters in isometrical hole and less than the diameter of screw cap portion greater than the external diameter of screw thread section.During use, some screws are placed in the groove of disk body, screw drops in the screw hole and arranges when vibrating a little, and head absorption screw is operated on to increase work efficiency thereby be convenient to cross then up by the cap portion of screw.
As preferably, described bottom portion of groove is a planar structure, and described some screw holes evenly distribute at bottom portion of groove, thereby are convenient to optionally draw screw.
As preferably, the degree of depth of described groove is more than or equal to the diameter of screw cap portion, thereby can avoid screw when the groove internal vibration and drop out.
As preferably, the isometrical hole of described screw hole hypomere is a through hole, thereby can be fit to the use of the screw of all lengths, enlarges range of application of the present utility model.
Therefore, the utlity model has and be convenient to cross and operate on head and cooperate, be beneficial to the raising cross and operate on the characteristics such as operating efficiency of mounting screw with the cross recess of screw cap portion.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the B-B view of Fig. 1;
Fig. 3 is the A place partial enlarged drawing of Fig. 2.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as Fig. 1, Fig. 2 and shown in Figure 3, disk body 1 upper surface forms a groove 2, and the degree of depth of groove 2 is more than or equal to the diameter of screw cap portion, and the bottom of groove 2 is a planar structure, the bottom of groove 2 is provided with a plurality of screw holes 3, and screw hole 3 evenly distributes in the bottom of groove 2.Screw hole 3 is made of the bellmouth 4 of epimere and the isometrical hole 5 of hypomere, bellmouth 4 is small top and big bottom, the equal diameters in the lower end diameter of bellmouth 4 and isometrical hole 5 and less than the diameter of screw 6 cap portions greater than the external diameter of screw 6 thread segments, isometrical hole 5 is a through hole.
During use, as shown in Figures 2 and 3, some screws 6 are placed in the groove of disk body, screw 6 drops in the screw hole and arranges when vibrating a little, and head absorption screw is operated on to increase work efficiency thereby be convenient to cross then up by the cap portion of screw 6.
Claims (4)
1, a kind of screw dish, comprise disk body, it is characterized in that described disk body upper surface forms a groove, bottom portion of groove is provided with some screw holes, described screw hole is made of the bellmouth of epimere and the isometrical hole of hypomere, described bellmouth is small top and big bottom, the lower end diameter of bellmouth and the equal diameters in isometrical hole and less than the diameter of screw cap portion greater than the external diameter of screw thread section.
2, screw dish according to claim 1 is characterized in that described bottom portion of groove is a planar structure, and described some screw holes evenly distribute at bottom portion of groove.
