Abstract

The utility model relates to an opening chisel, including chisel rod body and the integrative chisel point of locating chisel rod body one end, the one end middle part that chisel rod body was kept away from to chisel point is offered and is used for the card to establish the joint opening at main shaft periphery side, and one side of chisel point is the plane for inclined plane, opposite side. When the flat chisel is used, the clamping opening on the flat chisel tip is clamped on the outer peripheral side of the main shaft, so that the flat chisel tip can conveniently rotate around the axis of the main shaft; the inclined plane of the flat chisel point is attached to the end face of the gear, and one end, far away from the flat chisel point, of the rod body of the flat chisel is knocked by a hammer. The utility model discloses structural design is simple, reasonable, solves the problem of flat chisel point both sides atress, and better protection one side can guarantee simultaneously that the gear atress is even, is showing improvement work efficiency.

Description

Flat chisel with opening

The technical field is as follows:

the utility model relates to an opening flat chisel.

Background art:

in the disassembling process of the internal gear in the narrow space inside the circuit breaker mechanism, because the gear is under long-term stress, the gear is connected with the main shaft more closely, dismantle the in-process again because the gear is got to the narrower unable claw horse that uses of spatial position, can only use the flat chisel that a current two sides all are the inclined plane to strike and take out, but take out the in-process because the flat chisel two sides are the inclined plane, one can lead to leaning on the terminal surface of axle side, the deformation is leaned on the inboard bearing housing of tip and can't be taken out, another is striking and takes out the in-process and can't guarantee the even atress in the gear all directions.

The utility model has the following contents:

the utility model discloses make the improvement to the problem that above-mentioned prior art exists, promptly the utility model aims to solve the technical problem that an opening flat chisel is provided, rational in infrastructure, convenient to use.

In order to realize the purpose, the utility model discloses a technical scheme is: an opening flat chisel comprises a flat chisel rod body and a flat chisel tip arranged at one end of the flat chisel rod body, wherein a clamping opening is formed in the middle of one end, far away from the flat chisel rod body, of the flat chisel tip, and one side of the flat chisel tip is an inclined plane and the other side of the flat chisel tip is a plane.

Furthermore, the joint opening is U type form, and the joint opening is close to the one end of flat chisel pole body and is the semicircle arcuation.

Further, the section of the spade chisel body is polygonal.

Furthermore, the end face of one end, far away from the flat chisel tip, of the flat chisel rod body is a knocking plane beneficial to knocking.

Compared with the prior art, the utility model discloses following effect has: the utility model has the advantages of simple and reasonable design, through joint opening and the cooperation of main shaft joint on the flat chisel point during the use, the inclined plane and the gear end face of flat chisel point are laminated mutually, solve the problem of flat chisel point both sides atress like this, and better protection one side can guarantee simultaneously that the gear atress is even, is showing improvement work efficiency.

Description of the drawings:

fig. 1 is a schematic front view of the embodiment of the present invention;

FIG. 2 is a schematic side view of an embodiment of the present invention;

fig. 3 is a schematic view of a usage status of the embodiment of the present invention.

The specific implementation mode is as follows:

the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1-3, the utility model relates to an opening chisel, including chisel rod body 1 and integrative chisel point 2 of locating chisel rod body 1 one end, chisel point 2 keeps away from chisel rod body 1 one end middle part and offers and is used for the card to establish the joint opening 4 at main shaft 3 periphery side, and one side of chisel point 2 is inclined plane 5, the opposite side is plane 6. When in use, the clamping opening 4 on the flat chisel tip 2 is clamped at the outer peripheral side of the main shaft 3, so that the flat chisel tip can conveniently rotate around the axis of the main shaft; the inclined surface 5 of the chisel edge 2 is jointed with the end surface of the gear 6, and the end of the chisel rod body 1 far away from the chisel edge 2 is knocked by a hammer 7. Because the inclined plane of one side of the flat chisel tip is attached to the end face of the gear, the problem of stress on two sides is solved in the knocking process, the flat chisel tip is well protected from being close to one side face of the main shaft, the gear can be uniformly stressed, and the working efficiency is improved.

In this embodiment, the clamping opening 4 is in a U shape, and one end of the clamping opening 4 close to the flat chisel rod body 1 is in a semicircular arc shape, so that the clamping opening can be better matched with the outer circumferential surface of the main shaft.

In the present embodiment, the section of the spade drill shaft 1 is polygonal, such as regular hexagon, regular octagon, etc., i.e. the spade drill shaft is a polygonal column. Preferably, in order to improve the firmness of the shank when held by hand, the outer surface of the shank may be provided with an anti-slip coating.

In this embodiment, the end face of the end of the chisel body 1 away from the chisel tip is a striking plane for facilitating striking by a hammer.

It should be noted that the opening width of the clamping opening 4 can be determined according to the diameter of the spindle.

The utility model has the advantages that: one side surface of the head of the traditional flat chisel is changed into a plane, and the clamping opening is arranged, so that the flat chisel can be in close contact with the gear, the problem of stress on two sides is solved, and one side is well protected; meanwhile, the flat chisel is convenient to move, the uniform stress of the gear is still ensured after the flat chisel is moved, and the working efficiency is obviously improved.

The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
