SOCKET REMOVABLY ATTACHED TO A TOOL AND HAVING DRIVING PROTRUSIONS

Abstract

A socket is portably and removably attached to a tool and includes a body with a mounting hole which includes multiple faces. Each face includes a first protrusion and two groups of second protrusions located on two sides of the first protrusion. The first protrusion of each face includes a first flat distal surface which has a certain length. Each second protrusion includes a second flat distal surface which is tilt relative to the first flat distal surface. The two respective slopes of the second flat distal surfaces of the two groups of the second protrusions are opposite to each other. A first imaginary plane is co-linear with the first flat distal surface. A second imaginary plane is co-linear with the second flat distal surfaces of each second protrusion. An angle is formed between the first and second imaginary planes. The socket can drive a normal or rounded bolt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0029] Referring to FIGS. 1 to 9, the socket 1 of the present invention is cooperated with a wrench 10 to loosen a bolt 20. The socket 1 comprises a body with a mounting hole 11 defined axially therethrough. The body is a tubular and elongate body. The body includes a connection section 12 and a driving section 13 which is located co-axially to the connection section 12. A mounting hole 11 is defined axially through the body. The mounting hole 11 is a first hole 131 in the connection section 12, and the mounting hole 11 is a second hole 132 in the driving section 13. The first hole is a rectangular hole, the second hole 132 is a polygonal hole. The connection section 12 is portable and removably attached to a tool such as a ratchet wrench. The driving section 13 is to be mounted to the bolt 20.

[0030] As shown in FIG. 3, the mounting hole 11 in the driving section 13 includes six faces 2, and each face 2 comprises a first protrusion 3 protruding from the central portion thereof. The first protrusion 3 of each face 2 includes a first flat distal surface 30 which has a certain length. A first imaginary plane 4 is co-linear with the first flat distal surface 30. 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. In this embodiment, each group of the second protrusions 8 includes two second protrusions 8. A triangular notch 81 is defined axially between the two adjacent second protrusions 8 of each group of the second protrusions 8. Each second protrusion 8 includes a second flat distal surface 80 which has a certain length and is tilt relative to the first flat distal surface 30. Specifically, the slope of each of the two second flat distal surfaces 80 of the two second protrusions 8 of each group is identical. The two respective slopes of the second flat distal surface 80 of the two groups of the second protrusions 8 are opposite to each other.

[0031] A second imaginary plane 5 is co-linear with the two second flat distal surfaces 80 of each group of the second protrusions 8. 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.

[0032] A curved groove 82 is defined axially between any of the adjacent faces 2 of the mounting hole 11.

[0033] As shown in FIGS. 4 and 5, when loosening a normal bolt 20, the six sides of the head of the bolt 20 are in contact with the faces 2 of the mounting hole 11. When rotating the wrench 10, the socket 1 is rotated to rotate the bolt 20.

[0034] As shown in FIGS. 5 to 9, when loosening a rounded or damaged bolt 20, the second flat distal surfaces 80 of the second protrusions 8 are at least partially in contact with the six sides of the head of the bolt 20 so that when rotating the wrench 10, the socket 1 is rotated to rotate the bolt 20.

[0035] One of the embodiments of the socket 1 is described hereinafter, wherein the length 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 length of each second flat distal surface 80 is 0.56 mm, and the length of each first flat distal surface 30 is 0.5 mm. The socket 1 of the present invention can effectively rotate normal or rounded/damaged nut or bolt.

[0036] 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.
