Abstract
The invention discloses a screw rod. The screw rod sequentially comprises a connecting segment, a screw-thread segment and a straight-bar segment, wherein the connecting segment, the screw-thread segment and the straight-bar segment are integrally formed. A positioning hole is formed in the middle of the connecting segment. A handle is arranged at the tail of the straight-bar segment. A groove is formed in the straight-bar segment. A protecting bush is arranged at the joint between the screw-thread segment and the straight-bar segment. An anti-skid piece is arranged at the top end of the connecting segment. The screw rod has the advantages that the structure is simple, usage is convenient, the screw rod can be accurately positioned in the transmission process due to the arrangement of the positioning hole, the requirements of production and machining are met, work efficiency is improved greatly, and the screw rod is well protected by the protecting bush.
Description
Technical field
The present invention relates to a kind of screw mandrel.
Background technique
Screw mandrel is generally used in the every field of machinery industry, and its major function is that rotation motion is converted into straight line motion.It is connected with driver part conventionally, and the pivotable transmission of power that driver part is provided is to the executive component being connected with screw mandrel.Screw mandrel, in transmission process, sometimes need its transmission position to limit, but existing screw mandrel often can not meet this requirement.
Therefore,, for addressing the above problem, spy provides a kind of new technological scheme.
Summary of the invention
The invention provides a kind of screw mandrel.
The technical solution used in the present invention is:
A kind of screw mandrel, this screw mandrel body comprises integrated linkage section, thread section and straight bar section successively, described linkage section middle part has positioning hole, described straight bar section afterbody is provided with handle, on described straight bar section, have groove, be provided with sheath at thread section and straight bar section place, described linkage section top is provided with the sheet that skids.
The width of described positioning hole is 8-10mm.
The length of described linkage section is less than the length of thread section.
The invention has the beneficial effects as follows: simple in structure, easy to use, the setting of positioning hole can accurately be located screw mandrel in transmission process, meets the needs of production and processing, has greatly improved working efficiency, and sheath plays a very good protection to screw mandrel.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, linkage section, 2, thread section, 3, straight bar section, 4, positioning hole, 5, handle, 6, groove, 7, sheath, 8, sheet skids.
Embodiment
In order to deepen the understanding of the present invention, be described in further detail of the present invention below in conjunction with embodiment and accompanying drawing, this embodiment only, for explaining the present invention, does not form the restriction to protection scope of the present invention.
As shown in Figure 1, a kind of screw mandrel of the present invention, this screw mandrel body comprises integrated linkage section 1, thread section 2 and straight bar section 3 successively, linkage section 1 middle part has positioning hole 4, and the width of positioning hole 4 is 8-10mm, and straight bar section 3 afterbodys are provided with handle 5, on straight bar section 3, have groove 6, be provided with sheath 7 at thread section 2 with straight bar section 3 places, linkage section 1 top is provided with the sheet 8 that skids, and the length of linkage section 1 is less than the length of thread section 2.
The invention has the beneficial effects as follows: simple in structure, easy to use, the setting of positioning hole can accurately be located screw mandrel in transmission process, meets the needs of production and processing, has greatly improved working efficiency, and sheath plays a very good protection to screw mandrel.
The above, be only preferred embodiment of the present invention, is not the restriction of the present invention being made to any other form, and according to any modification or equivalent variations that technical spirit of the present invention is done, still belong to the present invention's scope required for protection.
Claims (3)
1. a screw mandrel, it is characterized in that: this screw mandrel body comprises integrated linkage section, thread section and straight bar section successively, described linkage section middle part has positioning hole, described straight bar section afterbody is provided with handle, on described straight bar section, have groove, be provided with sheath at thread section and straight bar section place, described linkage section top is provided with the sheet that skids.
