Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the steering knuckle comprises a sleeve, wherein an inner contact a2 and an inner contact B6 are arranged in the sleeve, an elastic piece 3 is arranged between the inner contact a2 and the inner contact B6 in a matching mode, under the elastic action of the elastic piece 3, the inner contact a2 is limited to the inner side of one end of the sleeve and can rotate relative to the sleeve, and the inner contact B6 is limited to the inner side of one end of the sleeve and can rotate relative to the sleeve. The inscription A2 comprises a rotary seat a201 confined in the sleeve and a coupling portion a202 protruding from the sleeve, and the inscription B6 comprises a rotary seat B601 confined in the sleeve and a coupling portion B602 protruding from the sleeve. Wherein the rotating seat A201 and the rotating seat B601 realize the rotation of the inner connection A2 and the inner connection B6, the connecting part A202 and the connecting part B602 realize the connection of the inner connection A2 and the inner connection B6 with the picking head, the handle, the quick connection and other mechanisms of a tool (such as a picker), and the connecting part A202 of the inner connection A2 shown in figure 1 is connected with the circumscribed line 1.

The sleeve includes interconnect's first sleeve 4 and second sleeve 5, and first sleeve 4 and second sleeve 5 can adopt threaded connection, also can adopt connected modes such as lock joint. The outer surfaces of the first sleeve 4 and the second sleeve 5 can be provided with lines such as knurls, so that the attractive effect is achieved on the one hand, and the anti-skidding effect is achieved when the anti-skidding effect is achieved.
