Abstract
The utility model discloses a novel screw which comprises a screw rod and a screw head arranged at the upper portion of the screw rod. A circular convex block and a backup wrench screwing seat are arranged between the screw head and the screw rod, the convex block is arranged at the upper portion of the backup wrench screwing seat, and a ring of groove is formed in the convex block. The novel screw is simple in structure and ingenious in design. Once the screw of the structure is fractured in use, fracture only appears at the position of the groove because the position of the groove bears small torsion force. When the screw is broken, an operator can utilize a wrench to continuously rotate the screw at the position of the backup wrench screwing seat. Therefore, the novel screw is novel in design and is a novel technical scheme convenient to popularize.
Description
Technical field
The utility model relates to the hardware ﹠ tools field, particularly relates to a kind of novel screw.
Background technique
Present existing screw the phenomenon of fracture easily occurs in the process of using, once work as broken screw in equipment, just be difficult to take out, and will affect so the normal operation of equipment.
In sum, for the defective of prior art, need especially a kind of novel screw, thereby solve above-mentioned problem.
Summary of the invention
The utility model mainly solves the prior art problem, and a kind of novel screw is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of novel screw is provided, comprise screw rod and the spiral shell head that is arranged on the screw rod top, be provided with round bump between described spiral shell head and screw rod and standby spanner is turned on seat, projection is arranged on the top that standby spanner is turned on seat, and described projection is provided with a circle groove.
In preferred embodiment of the utility model, described projection, standby spanner are turned on seat, spiral shell head and screw rod integrated setting.
In preferred embodiment of the utility model, the diameter that the diameter of described projection and standby spanner are turned on seat equals the diameter of screw rod.
In preferred embodiment of the utility model, the degree of depth of described groove is greater than the degree of depth of screw thread on screw rod, so the torsion that just bears less than the screw thread place of the torsion that bears of groove.
Beneficial effect is: the utility model is simple in structure, designs ingeniously, and the screw of this spline structure only can be in the groove fracture, because the torsion that groove bears is little in use once fracture.After screw disconnected, operator can adopt spanner to turn on seat place's continuation knob screw at standby spanner.Novel in design like this, be a kind of new technological scheme, be convenient to promote.
Description of drawings
Fig. 1 is plan view of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of novel screw described in the utility model, comprise screw rod 1 and the spiral shell head 2 that is arranged on screw rod 1 top, be provided with round bump 3 and standby spanner between described spiral shell head 2 and screw rod 1 and turn on seat 4, projection 3 is arranged on the top that standby spanner is turned on seat 4, and described projection 3 is provided with a circle groove 5.Standby spanner is turned on seat 4, spiral shell head 2 and screw rod 1 integrated setting.The diameter of projection 3 and standby spanner are turned on the diameter that seat 4 diameter equals screw rod 1.The degree of depth of groove 5 is greater than the degree of depth of screw thread on screw rod 1.The utility model is simple in structure, designs ingeniously, and the screw of this spline structure only can be in the groove fracture, because the torsion that groove bears is little in use once fracture.After screw disconnected, operator can adopt spanner to turn on seat place's continuation knob screw at standby spanner.Novel in design like this, be a kind of new technological scheme, be convenient to promote.
The above is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
