Description
Technical field
This utility model relates to scribing by bench worker instrument, is specifically related to the scriber of a kind of needle point that prevents from fractureing.
Background technology
Pincers worker is the very important work post of machine industry, and along with the extensive application of the fast-developing and high-end Precision Manufacturing Technology of equipment manufacture, pincers worker status in manufacturing industry is more and more higher.Line is one of basic skill of pincers worker, and the degree of accuracy of line and definition directly influence surface quality and the positional precision of following process.The instrument of line mainly have scriber, plan, tosecan and vernier height gauge, wherein scriber is the most commonly used instrument.Owing to the tip of scriber wears into 15 °～20 °.Thin and point, hardness height and frangibility needle point are the feature of scriber, especially with the scriber of copper bond hard alloy needle point, more fragile needle point.The needle point of scriber once fractures, and not only can affect the progress of line work, and be difficult to again repair use, generally scraps process, thus makes a large amount of wastes of scriber.
Chinese patent also has some utility model improving scriber and inventions, but its technical scheme exists operation inconvenience, must separate with protection part when using scriber, protection device loss easily damaged, easy, the technological deficiency such as yielding.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, the scriber of the easy to use needle point that prevents from fractureing; there is needle point frangibility in the used scriber that it can solve to be mentioned in background technology, and is difficult to repair the technical problem of fragile, the yielding and easy loss of protection device present in the defect reused and state-of-the-art technology scheme.
For reaching above-mentioned purpose, this utility model is a kind of to be prevented from fractureing the scriber of needle point, and it includes scriber body, protection set and clamp screws; the cross section of described scriber body is rounded; upper end is provided with hook, and lower end is provided with needle point, and described needle point is fixed on scriber body by welding material；The external face of described scriber is provided with protection set, and the middle and upper part of described protection set is provided with screwed hole, and the lower end of protection set is provided with taper hole；Being provided with clamp screws in described screwed hole, the head of described clamp screws is provided with annular knurl.
In technique scheme, described taper hole is identical with the tapering of needle point.
After using technique scheme, rotate clamp screws, can realize in scriber body stretches out in protecting set or returns to protection set and overlap reliable fixing with protection, thus avoiding needle point surprisingly to fracture, causing use inconvenience to waste with instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of the scriber of a kind of needle point that prevents from fractureing.
Accompanying drawing is respectively designated: 1, scriber body, 11, hook, 12, needle point, 13, welding material, 2, protection set, 21, screwed hole, 22, taper hole, 3, clamp screws, 31, annular knurl.
Detailed description of the invention
The scriber of prevent from fracture needle point a kind of to this utility model further illustrates below in conjunction with the accompanying drawings:
As seen from Figure 1, this utility model it include scriber body 1, protection set 2 and clamp screws 3,1 cross section of described scriber body is rounded, and upper end is provided with hook 11, and lower end is provided with needle point 12, and described needle point 12 is fixed on scriber body 1 by welding material 13；Being provided with protection set 2 outside described scriber body 1, the middle and upper part of described protection set 2 is provided with screwed hole 21, and the lower end of protection set 2 is provided with taper hole 22；It is provided with clamp screws 3 in described screwed hole 21.
Using method of the present utility model is: when using scriber line, rotating clip can hold screw 3 counterclockwise, the needle point 12 of scriber body 1 front end will stretch out in taper hole 22, then clamp screws 3 forward clamps scriber body 1, and scriber can be used to rule；When temporarily need not or during long-term storage scriber, clamp screws 3 can be unclamped, make scriber body 1 be retracted in protection set 2, then clamp screws 3 is clamped scriber body 1.
In the present embodiment, described needle point 12 is identical with the tapering of taper hole 22, and when needle point 12 so can be made to stretch out protection set 2, the surface of needle point 12 fits tightly with the inner surface of taper hole 22, it is ensured that stability during use and reliability；Use scriber whole during, protection set 2 and scriber body 1 between connect together all the time, thus avoid protection set 2 loss and damage；Described protection set 2 can use plastics or rubber to make, and can improve comfortableness when using scriber.
In the present embodiment, for the ease of carrying, the upper end of described scriber body 1 is provided with hook 11, and described hook 11 can hang on clothes pocket or on file；The head of described clamp screws 3 is provided with annular knurl 31, and annular knurl 31 can increase the friction between finger and screw head, flexible during operation clamp screws 3.
This utility model reasonable in design, use flexibly and are easy to carry, and can effectively solve existing with to obtain scriber frangibility needle point, thus affect line work, it is possible to extend the service life of scriber.
