The present invention has been fully supplemented by reinforcing the inconveniences of the invention of the applicant already filed 86-5203.

Conventional ratchet wrenches are equipped with various specifications of the box (socket) in the tool set, and when used, the appropriate size of the box is selected and used in the ratchet handle. Also often lost.

In the case of the monkey spanner, the time required to adjust the mounting and the manual operation such as turning and unplugging and re-inserting and unplugging each time the fixing was much wasted.

The present invention is designed to solve these various shortcomings and perform an efficient function, and relates to an auto-adjustable socket wrench having a simple and fast mounting time without the need for multiple sockets.

If the operator first turns the circuit control plate 2 counterclockwise before using it on a bolt or nut, the bleed portions 6 and 6 'are spread to the left and right to widen the gap, and the widened bolt bleed portions 6D and 6'D ) After inserting the bolt or nut into the rotary control plate (2) is mounted and the adjustment bar (11) in the desired direction to hold the handle (7) to tighten or loosen it.

The structure is as follows.

A spring 9 is inserted into the rotating plate spring hanger 8 and one end 9a is inserted into the spring hanger groove 4c in the inner spring groove 4b of the rotary control plate 2 and is fixed to the rotary control plate 2 and the spring 9 is provided. Another end of the 9b is connected to the rotary gear spring hook 10 and is fitted to move along the V-shaped groove (5e) and the bite moving groove (5b) in the interior of the rotary gear (5) The upper end faucet 6c, 6'c of the part 6, 6 'is fitted in close contact with each other while being fitted with the upper end grooves 3, 3a of the upper part, respectively, and the surface of the rotation control plate frame 2a is covered. The opposite side of (1) is in close contact with each other, and the assembled parts are supported by the handle base 7c through the rotary gear groove 5c, and the ratchet groove 7b is disposed between the ratchet 12 and the adjustment. It is a structure which is assembled to the adjustment chamber 11 through the hole 1a.

The effect of the invention devised as described above is as follows based on the drawings.

First, the state of FIG. 5A is a cross-sectional view taken along the line B-B of FIG. 5 so that the ratchet 12 cannot move the rotary gear 5 counterclockwise.

In order to mount the object, the user rotates the rotation control plate counterclockwise so that the rotation plate spring hook 8 assembled to the rotation control plate 2 extends while pulling the spring 9.

Of course, at this time, the other end 9b connected to the rotary gear spring hook 10 of the spring 9 is counterclockwise due to the role of the ratchet 12 because the rotary gear spring hook 10 is engaged with the rotary gear 5. Can not move.

At this time, while rotating in the same direction as the top of the chamfer grooves (3, 3a) of the top of the bleeding portion 2 inside the rotation control plate (2) to move along the bleed portion moving groove (5b) It is opened and it becomes the state of FIG. 6A, and a bite part spreads to the left and right, and becomes a target mounting state.

If you remove your hand from the next rotation control plate (2) in the reverse order of this operation, the bolt or nut is mounted.

5B is a cross-sectional view taken along the FF of FIG. 3B, and the spring 9 extends along the bite fastening jaws 6d and 6'd along the bite moving groove 5b. By the movement of the bite upper end 6c, 6'c to the left and right to be in the state of Fig. 6b. Next, when the hand is released from the rotation control plate (2), the spring (9) decreases, the whale lamp (4, 4a) is in close contact with the bite clamping jaw (6b, 6'b) and rotates the bite clamping (6b, 6'b 5), the state becomes as shown in FIG. 5B, and the bolt or the nut is tightened and the user can operate the handle by adjusting the adjustment.

Claims (1)

The rotation control plate (2) has a whale back bump (4, 4a) and the upper tap groove (3, 3a) and the spring groove (4b) on the rotation control plate (2) and the V-shaped groove ( 5e) and self-adjusting socket wrench designed to be fast-mounted and socket-free by inserting bites (6,6 ') by making bite moving grooves (5b).
