Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In this embodiment, referring to fig. 1-3, a bidirectional ratchet type socket head cap screw wrench includes a main pulling means 1 and a supporting wrench rod 2, the supporting wrench rod 2 is rotatably installed at the tail end of the main pulling means 1 through a connecting seat 3, a rotating shaft 4 is installed inside the connecting seat 3 through a bearing component, a ratchet 5 and a sleeve 6 are sleeved on a shaft rod of the rotating shaft 4, the ratchet 5 and the sleeve 6 rotate coaxially, a movable rod 9 is inserted on the side wall of the connecting seat 3, the movable rod 9 is arranged toward the center of the ratchet 5, a notch 12 matched with the ratchet of the ratchet 5 is opened on the end surface of the movable rod 9 located at the inner side of the connecting seat 3, a ball handle 13 is arranged at the end of the movable rod 9 located at the outer side of the connecting seat 3, the connecting seat 3 moves toward or away from the ratchet 5, the gap 12 is clamped on the ratchet of the ratchet wheel 5, and the outer part of the sleeve 6 is sleeved with the wrench rod 2.

A through hole 7 is formed in the side wall of the connecting seat 3, and the wrench rod 2 penetrates through the through hole 7 and extends to the outside of the connecting seat 3. The side wall of the connecting seat 3 is provided with a guide groove 8, and the movable rod 9 passes through the guide groove 8. The body of the movable rod 9 is sleeved with a fixed plate 10 and a spring 11. The fixing plate 10 and the spring 11 are both located in the guide groove 8.
