摘要： A ball type universal joint includes a coupling member and a socket member combined together. The socket member has a ball head and lugs projectingly formed on a surface of the ball head. A surface between two neighboring lugs is a spherical surface. The coupling member has a cylindrical coupling hole. Ribs are projectingly formed on a wall surface of the cylindrical coupling hole. One side of each rib is a protrusion surface, and a lengthwise extending direction of the protrusion surface is an extending direction of a straight line. The ball head is coupled to the cylindrical coupling hole. Each lug is disposed between two ribs. Each rib is disposed between two lugs and corresponds to the spherical surface. A combination of the coupling member and the socket member may be adjusted into an angled state. The spherical surface is tangent to a protrusion surface of the rib.

摘要： An elastic short-pin type universal joint comprises a first base, a second base and a connection member. The connection member has a first hole, a second hole, a third hole and a fourth hole each being disposed at the same level from the connection member. Wall surfaces of the first base and the second base have slots corresponding to the holes, respectively. An elastic assembly is disposed in each hole, and one end of each elastic assembly rests against one slot. Thus, the length of the connection member can be shortened, and the length or size of the universal joint can be reduced. In addition, each elastic assembly can be easily and rapidly installed.

摘要： An elastic short-pin type universal joint includes a first base, a second base, a jointer, a first elastic member, two second elastic members, and four short pins. The first base engages the second base to form a space therebetween. The jointer is received in the space between the first and the second bases. The jointer has a first bore passing through the jointer, a second bore, and a third bore. The first elastic member is received in the first bore of the jointer, and the second elastic members are received in the second bore and the third bore. The short pins are urged by ends of the first elastic member and the second elastic members to press the first base and the second base respectively. As a result, the first base is able to rotate related to the second base in all directions.

摘要： A universal joint includes a socket member and a driving member. The socket member includes a receiving hole, and an inner periphery of the receiving hole is formed with first evading portions and first abutting portions staggered with each other to cause the first abutting portions not connected to each other. Each first abutting portion is provided with a first abutting face, a second abutting face, and an adjacent edge formed between the first abutting face and the second abutting face. One side of the adjacent edge forms an adjacent edge angle being greater than 177 degrees and less than 180 degrees. The driving member includes a rounded base arranged in the receiving hole and a driving column opposite to the rounded base.

摘要： A multi-function tool with a fixing function comprises a handle body having a receiving slot; a ratchet handle being a combination of a rod body and a work head, the rod body being pivotally mounted on the receiving slot, and a surface of one end of the rod body having a toothed portion; a mounting, hole formed on an end portion of the handle body and abutting upon the receiving slot; a ball hole formed on a bottom surface of the mounting hole and communicating with the receiving slot; and a positioning assembly constituted by a push block, a spring and a steel ball, the push block surface having a positioning cavity and a release cavity, the push block being connected to the spring and disposed in the mounting hole, the steel ball being disposed in the ball hole. The push block is moved so that the steel ball meshes with the toothed portion of the rod body and the positioning cavity, and the ratchet handle is positioned. The push block is moved so that the steel ball is disposed between the release cavity and the toothed portion, and the ratchet handle can be rotated. Thus, the ratchet handle can change the angle of the handle body and be retracted into the handle body, and the locking mechanism of the positioning assembly can make, the ratchet handle have a stable positioning effect.
