Socket structure
View Patent ↗A socket includes a first section and a second section. The first section is to be connected with a tool. The second section includes an outer face, and a mounting hole is axially defined through the second section and communicates through the first section. The mounting hole includes multiple recesses and multiple sides defined in the inner periphery thereof. The multiple recesses and the multiple sides are located alternatively with each other. Each recess includes a rounded corner formed radially in the inner portion thereof. A triangular groove is formed axially and centrally in each side. The angle between two insides of each groove is smaller than 90 degrees. A rusted or damaged bolt head is engaged with either the rounded corners or the grooves so as to be effectively rotated.
1. A socket comprising:
a first section and a second section which is formed with the first section;
the second section including an outer face, a mounting hole axially defined through the second section and communicating through the first section, the mounting hole being smaller than a diameter of the outer face of the second section, multiple recesses and multiple sides defined in an inner periphery of the mounting hole, the multiple recesses and the multiple sides being located alternatively with each other, each recess including a rounded corner formed radially in an inner portion thereof, a groove formed axially and centrally in each side and being a triangular groove, an angle between two insides of each groove being smaller than 90 degrees, and
each of the sides of the mounting hole including a first subside and a second subside, the groove located between the first subside and the second subside, the first subside and the second subside respectively communicating with the recess corresponding thereto, each of the first subside and the second subside of each side being a straight side.
2. The socket as claimed in claim 1 , wherein a distance between two adjacent rounded corners is larger than a distance between two adjacent grooves.
3. A socket comprising:
a first section and a second section which is formed with the first section;
the second section including an outer face, a mounting hole axially defined through the second section and communicating through the first section, the mounting hole being smaller than a diameter of the outer face of the second section, multiple recesses and multiple sides defined in an inner periphery of the mounting hole, the multiple recesses and the multiple sides being located alternatively with each other, each recess including a rounded corner formed radially in an inner portion thereof, a groove formed axially and centrally in each side and being a triangular groove, an angle between two insides of each groove being smaller than 90 degrees, and
each of the sides of the mounting hole including a first subside and a second subside, the groove located between the first subside and the second subside, the first subside and the second subside respectively communicating with the recess corresponding thereto, the first subside and the second subside of each side being parallel to each other.
4. The socket as claimed in claim 3 , wherein a distance between two adjacent rounded corners is larger than a distance between two adjacent grooves.
