This creation is about a "multi-angle transmission tool structure", especially a multi-angle transmission tool structure that can transmit large forces and withstand large torques.

According to the conventional multi-angle transmission tool, as shown in the attached file, it is the "angle adjustment joint of the ratchet screwdriver" approved by the Bureau of the People's Republic of China on June 21, 1988. Mainly, a connecting rod (20) is sleeved on the upper end of the ratchet driver (10), and an angle adjusting universal joint structure (30) is sleeved in the connecting rod (20), wherein the angle adjusting universal joint structure is (30) The upper and lower joints (31) (32) are internally provided with a worm spring (34), and a through hole (313) (323) is bored through the joint wall surface, so that the tip (36) can be pivoted. a rotating shaft (33), wherein the upper and lower ends of the rotating shaft (33) are respectively formed with corresponding spherical rotating portions (331), and an arc is cut through the radial direction of the spherical rotating portion (331). The perforation (332) is pivotally fixed to the upper and lower joints (31) (32) so that the rotating shaft (33) can be turned into a proper bending angle, and a compression spring (35) is sleeved in the rotating shaft (33). ), as a user of the upper and lower joints (31) (32).

However, the conventional structure as described above still has the following problems in practical applications: the two tips (36) are kept parallel and are disposed at the same horizontal angle at the two joints (31) (32). ) In the through hole (313) (323), in this configuration, the transmission of a large force cannot be performed, and the large torque cannot be withstood, and the use is limited.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional multi-angle transmission tools is indeed the goal of the relevant industry to develop and research. The present creator has the idea of thinking and creation, and has many years of experience. The design, the multi-party discussion and trial sample test, and many corrections and improvements, is the launch of this creation.

The two ends of the conventional multi-angle transmission tool are kept parallel and are inserted in the through holes of the two joints at the same horizontal angle, so that the structure configuration cannot transmit large force and cannot withstand large torque. It is the technical problem that is to be solved.

The present invention provides a multi-angle transmission tool structure, comprising: a first joint, a second joint, two elastic members, a post and two pivots, wherein the first joint is provided with a polygonal card at both ends thereof a hole and a circular sleeve hole, a polygonal post and a circular sleeve hole are respectively arranged at two ends of the second joint, and the driving head of the tool such as a wrench is provided by the card hole of the first joint, and the first The post of the two joints can be used for connecting the sleeve, and the first joint is provided with a first fixing hole penetrating through the wall surface of the sleeve hole, and the second joint is provided with a wall extending through the wall of the sleeve hole. Second fixed a hole, and the first fixing hole and the second fixing hole have a difference in a penetrating direction, so that the two fixing holes can maintain a cross-shaped misalignment, and a ball head is respectively enlarged at both ends of the rod, and the ball is on the ball A first through hole and a second through hole are formed through the outer spherical surface of the ball head, and the first through hole and the second through hole have a difference in the through direction, so that the two through holes can maintain a cross-shaped misalignment. So, to get a multi-angle transmission tool structure.

The present invention provides a multi-angle transmission tool structure, which utilizes the difference between the first fixing hole and the second fixing hole, the first perforation and the second perforation, so that the post-piercing pivot is angularly displaced, which enables the Multi-angle transmission tools can transmit large forces and can withstand large torques, avoiding the limitations of use.
