DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model; obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As Figure 1and Figure 2 As shown in the drawings, a connecting rod ball head quick clamping device comprises a tool body 1, a sleeve 2, a cam rotating handle 3 and a pad 4.

[0022] The tool body 1 is in the shape of a V, and a first accommodating groove 5 is formed in the first arm of the tool body 1, and a second accommodating groove 6 is formed in the second arm of the tool body 1. The first accommodating groove 5 is circular and is divided into two sections with different diameters.

[0023] The sleeve 2 is rotationally arranged in the first accommodating groove 5, and the end face of the sleeve 2 is flush with the first side face of the first arm of the tool body 1, and the bottom end of the sleeve 2 extends beyond the second side face of the first arm of the tool body 1. The top of the sleeve 2 is concave downward to form an internal hexagonal groove 7 which is adapted to the hexagonal nut of the knuckle housing. Specifically, the sleeve 2 is divided into two sections, and the upper section is larger in size than the lower section. The upper section is in a cylindrical structure and is rotationally fitted in the section with the larger diameter of the first accommodating groove 5, and the lower section is in a regular hexagonal columnar structure and is arranged in the section with the smaller diameter of the first accommodating groove 5, and the bottom end of the lower section extends to the outside of the second side face of the first arm of the tool body 1 so as to be cooperated with a wrench.

[0024] In addition, a bushing 10 is arranged between the upper section of the sleeve 2 and the tool body 1, and the bushing 10 can facilitate the installation of the sleeve 2 and reduce the friction coefficient of rotation. Preferably, the bushing 10 is detachably fixedly connected with the tool body 1 by a set screw.

[0025] A square hole 11 is formed in the center of the lower section of the sleeve 2, and the square hole 11 extends through the lower section of the sleeve 2 and communicates with the internal hexagonal groove 7.

[0026] The cam rotating handle 3 is provided with a circular connecting part 8 at the first end, and the circular connecting part 8 is rotationally connected in the second accommodating groove 6, and a connecting pin shaft 12 is located at the eccentric position of the circular connecting part 8. The connecting pin shaft 12 is rotationally connected with the tool body 1, and the circular connecting part 8 is detachably fixedly connected with the connecting pin shaft 12 by a set screw. Since the connecting pin shaft 12 is located at the eccentric position of the circular connecting part 8, the circular connecting part 8 will be pressed downward when it is rotated.

[0027] The pad 4 is arranged at one side of the circular connecting part 8, and the top face of the pad 4 abuts against the circular connecting part 8, and the bottom face of the pad 4 is provided with a matching groove 9 which is adapted to the ball head nut of the knuckle housing.
