The present invention relates to a socket, and more particularly, to a socket with a mounting hole, and each face of the mounting hole includes a first protrusion and multiple second protrusions for loosening a rounded or damaged object.
Sockets are provided with a mounting hole which generally is a polygonal hole, the polygonal hole includes multiple faces which are designed to be in contact with sides of a nut or a bolt head. The sockets can be connected with a tool such as a wrench, and when the wrench is rotated, the socket is rotated to loosen the nut or bolt head. However, if the nut or bolt head is rounded or damaged, the faces of the polygonal hole are not in contact with the sides of the nut or bolt head, then the rotation of the socket cannot drive the nut or bolt head.
The present invention intends to provide a socket that includes protrusions on each face of the mounting hole of the socket so as to be securely engaged with the object to eliminate the shortcomings mentioned above.
The present invention relates to a socket and comprises a body with a mounting hole which includes multiple faces. Each face includes a first protrusion protruding from the central portion thereof. A first imaginary plane extends in parallel from the distal surface of each first protrusion. Two second imaginary planes respectively extend laterally from the center of the distal surface of each first protrusion. An angle is defined between the first imaginary plane and each of the second imaginary planes. Multiple second protrusions protrude from each face of the mounting hole and are arranged into two groups respectively locate don two sides of the first protrusion. Each of the second imaginary planes pass respective distal surfaces of the second protrusions of each group in parallel.
Preferably, the angle is larger than 0 degree, and the maximum value of the angle is 5 degrees.
Preferably, the angle is 2 degrees
Preferably, a groove is defined axially between adjacent faces of the mounting hole.
Preferably, a notch is defined axially between adjacent second protrusions.
Preferably, the body includes a connection section and a driving section. The mounting hole in the connection section is a first hole which is a rectangular hole, and the mounting hole in the driving section is a second hole which is a polygonal hole.
The primary object of the present invention is to provide a socket which is able to be securely mounted to a rounded or damaged nut or bolt head, and is able to loosen the rounded or damaged nut or bolt head.
The present invention will become more apparent from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The mounting hole 11 in the driving section 13 includes multiple faces 2, and each face 2 comprises a first protrusion 3 protruding from the central portion thereof. A first imaginary plane 4 extends in parallel from the distal surface of each first protrusion 3. Two second imaginary planes 5 respectively extend laterally from center of the distal surface of each first protrusion 3. An angle 7 is defined between the first imaginary plane 4 and each of the second imaginary planes 5. The angle 7 is larger than 0 degree, and the maximum value of the angle 7 is 5 degrees. Preferably, the angle 7 is 2 degrees.
Multiple second protrusions 8 protrude from each face 2 of the mounting hole 11 and are arranged into two groups. The first protrusion 3 is located between the two groups of the second protrusions 8. Each of the second imaginary planes 5 passes respective distal surfaces of the second protrusions 8 of each group in parallel. That is to say, as shown in
As shown in
As shown in
One of the embodiment of the socket 1 is described hereinafter, wherein the width of each face 2 is 55 mm, and the width of each notch 81 is 0.38 mm and the depth of each notch 81 is 0.1 mm. The width of each second protrusion 8 is 0.56 mm, and the width of each first protrusion 3 is 0.5 mm. The socket 1 of the present invention can effectively rotate normal or rounded/damaged nut or bolt.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
