Button, saw head and saw handle, the axe set are connect with de- tear open of axe, and the axe handle takes off with axe to be torn connection open and can replace different shaped
Marking axes head, the axe are connect with saw handle with saw headgear inner cavity is hollow, the saw handle and saw head rotation connection, the axe set peace
Equipped with hanging nose, the saw head is equipped with buckle and closes with the engaging buckle of axe handle, and the axe two sides of the device are symmetrical, in use process
In be easy to appear clamping stagnation, and structure is complicated, not readily portable.
Summary of the invention
In order to improve above situation, a kind of safety of coal mines crash axe of the present invention provides one kind can be by slanting blade
The strength that arm is brandished is totally converted to blade, improves the safety emergency axe of operating efficiency.After force, in effect of inertia
Under, topple over to side, and then notch is opened outward, avoids clamping stagnation.
A kind of safety of coal mines crash axe of the present invention is achieved in that a kind of safety of coal mines emergency axe of the present invention by exerting a force
Arm, connector sleeve, main board, blade, inner support crotch and fastening screw composition, inner support crotch is placed in main board one end, described
Inner support crotch and main board are integrally formed, and more reinforcing ribs are equipped with inside the main board, the main board is at middle part
Arc fold bending forms two parts, and bending angle, between 115-135 degree, the main board is made of alloy material, the interior branch
It supports crotch thickness and is greater than main body panels, connection is placed on the outside of inner support crotch, and force arm one end is placed in connector sleeve, and logical
It crosses multiple fastening screws and connector sleeve is fixed, bending section, the crooked position force arm entire length are equipped on the force arm
A quarter, the line in bending section both ends axle center is acclivitous oblique line, is equipped with protection on the outside of the force arm
Set, the protective case are followed successively by spongy layer, rubber layer and cotton layer from inside to outside, and the diameter of described force arm one end is equal to connection
The internal diameter of set, blade are removably placed in the main board other end, the corresponding surface of the main board other end lateral surface and blade it
Between angle between 10-15 degree, the line in main board part side inclined-plane on the lower and bending section both ends axle center is mutual
In parallel.
Beneficial effect.
One, enabling to the direction of blade to brandish with arm, direction is consistent, improves the conversion of power.
Two, it prevents from splashing, avoids injuring operating personnel.
Three, it enables to the edge of a knife and contact surface gradually to cut, increases cutting stroke.
Four, simple and light, it is carried convenient for underground.
Five, after exerting a force, under effect of inertia, topple over to side, and then notch is opened outward, avoid clamping stagnation.

Specific embodiment:
A kind of safety of coal mines crash axe of the present invention is achieved in that a kind of safety of coal mines emergency axe of the present invention by force arm
(1), connector sleeve (2), main board (3), blade (4), inner support crotch (5) and fastening screw (6) composition, inner support crotch (5)
It is placed in main board (3) one end, the inner support crotch (5) and main board (3) are integrally formed, and the main board (3) is internal embedding
It is equipped with more reinforcing ribs, the main board (3) forms two parts in middle part arc fold bending, and bending angle is between 115-135 degree,
The main board (3) is made of alloy material, and inner support crotch (5) thickness is greater than main board (3) thickness, connector sleeve (2)
It is placed on the outside of inner support crotch (5), force arm (1) one end is placed in connector sleeve (2), and by multiple fastening screws (6) and even
Female connector (2) is fixed, is equipped with bending section on the force arm (1), the crooked position account for force arm (1) entire length four/
One, the line in bending section both ends axle center is acclivitous oblique line, is equipped with protective case on the outside of the force arm (1), institute
It states protective case and is followed successively by spongy layer, rubber layer and cotton layer from inside to outside, the diameter of described force arm (1) one end is equal to connector sleeve
(2) internal diameter, blade (4) are removably placed in main board (3) other end, main board (3) other end lateral surface and blade
(4) the angle between corresponding surface is between 10-15 degree, the part side inclined-plane and bending section two of the main board (3) on the lower
The line in end axle center is parallel to each other.
In use, holding force application rod when using crash axe, then brandishing downwards main board (3), and then main board (3)
Band cutting blade (4) is split into work surface, the line phase on the main board (3) part side inclined-plane on the lower and bending section both ends axle center
It is mutually parallel, and then force direction is consistent with the incision direction of cutting edge, it reduces to force resolution, outside main board (3) other end
Angle between side and the corresponding surface of blade (4) is between 10-15 degree, and then cutting knife cutting edge carries out gradually in cut process
Into reduction acts on dividing for local power, and when main board (3) is cut completely, inner support crotch (5) is to force arm (1)
It is supported, and inner support crotch (5) is toppled under effect of inertia to side, and then inner support crotch (5) drives main board
(3) notch is opened outward, avoids clamping stagnation, improve operating efficiency；
The present invention compares existing axe, and quality is smaller, easy to carry；
