Three-way ratchet wrench

Abstract

The invention provides a three-way ratchet wrench which comprises a body, a ratchet piece, two clamping pieces and a control piece, wherein one end of the body is provided with a drive part, the drivepart is connected with a holding part and is provided with a first accommodation part, a second accommodation part and a third accommodation part; the ratchet piece is rotatably arranged in the firstaccommodation part of the body, teeth are circularly arranged on the side wall surface of the outer edge of the ratchet piece; the two clamping pieces are respectively arranged at two ends in the accommodation part of the body in a slip way, one side of each clamping piece opposite to the ratchet piece is provided with teeth, the first ends of the two clamping pieces facing to the ratchet piece are respectively provided with a guide part; the control piece is pivoted in the third accommodation part of the body, one end of the inner side of the control piece is provided with a direction control part, and the direction control part can selectively push the guide parts of the clamping pieces, wherein the depth of the third accommodation part does not exceed the center line of the second accommodation part to enable the first ends of the clamping pieces to largely support against the wall surface of the second accommodation part of the body, thereby improving the torque force born by theclamping pieces.

Description

Technical field [0001] The invention relates to a ratchet wrench, in particular to a three-way ratchet wrench. Background technique [0002] reference Picture 11 As shown in the structure diagram of the prior art, the ratchet wrench includes a wrench body 1, a ratchet gear 2, two brake blocks 3, a knob seat 4 and other components. The head 11 at one end of the wrench body 1 has a chamber 111, which communicates with the brake groove 12 penetrating the side of the head 11, and happens to be able to accommodate components such as the ratchet gear 2, the brake block 3, etc. , And make it a mesh configuration. The wrench body 1 is drilled at a suitable position on the top edge of the head 11 with a rotary seat hole 13 for the knob seat 4 to be accommodated. The rotary seat hole 13 happens to be in communication with the middle edge of the brake groove 12 to make the knob The top part 42 of the seat 4 can touch one of the brake blocks 3, and can change the direction in which the rat...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is that the hole depth of the swivel hole of the ratchet wrench in the prior art is about 3 / 4 of the thickness of the wrench body, the deep hole of the swivel hole weakens the structural strength of the head, and makes the The front end of the brake block is completely suspended in the hole of the swivel seat, and the torque it bears cannot be transmitted to the main body of the wrench, which seriously affects the torque value that the brake block can withstand
