This tertiary spiral shell sword includes tool bit, interlude and centre gripping section, and the interlude is located between centre gripping section and the tool bit, passes through the chamfer between tool bit and the interlude, has a step face that is located on the centre gripping section terminal surface between interlude and the centre gripping section, has an annular on the step face, and the width of annular is greater than the diameter of tool bit tip. The utility model has the advantages of preventing dust pollution.
Description
Technical Field
The utility model belongs to the technical field of the PCB board processing cutter, a tertiary spiral shell sword is related to.
Background
The PCB processing cutter has smaller and smaller specifications along with higher and higher integration level of electronic products, cutters with different specifications and sizes are applied to processing of PCBs with different apertures and different purposes, and cutters with large sizes cannot be used after being used and scrapped and are often used for processing cutters with small sizes, namely, the diameter and the length of the cutters are reduced, so that the cutters with small specifications become cutters with one or more sizes.
In order to improve the strength of the tool, the large-sized tool is sometimes machined secondarily into a three-level tool, and the adjacent levels of the conventional three-level tool are smoothly transited, so as to improve the strength and the machining convenience, but due to the small diameter of the tool bit, chips generated in the machining process are sprayed into the end of the clamp along with the smoothly transited transition surface, and actually, the strength of the tool plays an insignificant role in the clamping end of the three-level tool.
The smaller the size of the knife, the more difficult it is to package it, which is prone to breakage and damage during transportation and handling.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tertiary spiral shell sword to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that how to make the cutter have the effect of separating the shelves processing dust.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a tertiary spiral shell sword, its characterized in that, this tertiary spiral shell sword includes tool bit, interlude and centre gripping section, the interlude is located between centre gripping section and the tool bit, pass through the chamfer between tool bit and the interlude, have a step face that is located on the centre gripping section terminal surface between interlude and the centre gripping section, an annular has on the step face, the width of annular is greater than the diameter of tool bit tip.
The advantage of doing so lies in, the bits end that the in-process that the cutter processed the PCB board receives the effect of annular and the redirecting, can not cause the pollution to the equipment more than the anchor clamps, also effectually prevented simultaneously that the bits end that the in-process that the processing PCB board caused from splashing and influence the problem of workshop environment.
The utility model provides a spiral shell sword packing carton, its characterized in that, this mounting box includes the box body, two baffles that have longitudinal distribution in the box body, two baffles are parallel to each other, equidistant a plurality of mounting holes that are provided with on the baffle, the outer fringe department of mounting hole has the bellied annular protruding muscle in the baffle outside, a locating notch has on the protruding muscle.
The annular groove of the cutter corresponds to the convex rib, and the cutter head of the other opposite cutter is inserted into the positioning notch of the annular groove, so that the storage space of the packaging box is utilized to the maximum extent, the cutters cannot collide with each other, the swinging and swinging freedom of the cutters in the packaging box is limited, the reliability of transportation and carrying is improved, and the cutters are very convenient to take and place.
The box body is made of plastic materials, and two sides of the box body are respectively provided with a turnover cover.

Fig. 1 is a schematic structural view of the present three-stage screw driver.
Fig. 2 is a schematic structural view of the packing box.
Fig. 3 is a perspective view of the separator.
In the figure, 1, a tool bit; 2. a middle section; 3. a clamping section; 4. a ring groove; 5. a box body; 6. a partition plate; 61. mounting holes; 62. a rib is protruded; 63. and positioning the notch.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, the three-stage screw driver comprises a cutter head 1, an intermediate section 2 and a clamping section 3, wherein the intermediate section 2 is located between the clamping section 3 and the cutter head 1, the cutter head 1 and the intermediate section 2 are in chamfer transition, a step surface located on the end surface of the clamping section 3 is arranged between the intermediate section 2 and the clamping section 3, an annular groove 4 is formed in the step surface, and the width of the annular groove 4 is larger than the diameter of the end part of the cutter head 1.
The advantage of doing so is that the bits end that the in-process that the cutter processed the PCB board produced receives the effect of annular 4 and changes the direction, can not cause the pollution to the equipment more than the anchor clamps, also the effectual problem that influences workshop environment that splashes of bits end that causes of the in-process that has prevented simultaneously to process the PCB board.
As shown in fig. 2 and 3, this mounting box includes box body 5, has two baffles 6 of longitudinal distribution in the box body 5, and two baffles 6 are parallel to each other, and equidistant being provided with a plurality of mounting holes 61 on the baffle 6, the outer fringe department of mounting hole 61 has to the bellied annular protruding muscle 62 in the baffle 6 outside, has a location breach 63 on the protruding muscle 62.
The annular groove 4 of the cutter corresponds to the convex rib 62, and the cutter head 1 of the other opposite cutter is inserted into the positioning notch 63 of the annular groove 4, so that the storage space of the packaging box is utilized to the maximum extent, the cutters cannot collide with each other, the swinging and swinging freedom of the cutters in the packaging box is limited, the reliability of transportation and carrying is improved, and the cutters are very convenient to take and place.
The box body is made of plastic materials, and two sides of the box body 5 are respectively provided with a turnover cover.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
