Description

Ratchet wrench structure

The invention relates to a structure of a ratchet wrench, in particular to a ratchet wrench, wherein the tooth system is provided with a protrusion, and the protrusion is placed at a notch of the steering member, and the steering member is restricted by the tooth, and the steering member is pivoted It is located at the third tank.

As is known in the prior art, a ratchet wrench structure is used, such as U.S. Patent No. 2,957,377, which is based on a body 10 having a first receiving groove 13, a second receiving groove 16 and a third receiving groove. 24; a ratchet 14, the ratchet 14 is pivotally disposed at the first pocket 13, the outer peripheral ring of the ratchet 14 is provided with a ratchet portion 15; a tooth 19, the tooth 19 is received in the second pocket At the 16th end, the teeth 19 are provided with an annular arrangement of the engaging teeth 20, and the engaging teeth 20 are engaged with the ratchet portion 15, and the toothing 19 is provided with a groove 27 on the other side; a steering knob 23, The steering knob 23 is pivotally disposed at the third pocket 24, and the steering knob 23 is provided with a limiting groove 28; an elastic body 26, one end of which is disposed at the groove 27 of the tooth 19, the elastic body The other end is placed at the restriction groove 28 of the steering knob 23; the body 10, the ratchet 14, the tooth 19, the steering knob 23 and the elastic body 26 are basic components constituting a ratchet wrench, and the steering knob 23 is in the third When the cavity 24 rotates, the elastic body 26 is rotated at an angle, and the elastic body 26 drives the tooth 19 to be displaced at the second receiving groove 16, thereby forming a positive and negative of the ratchet wrench. Turn control, this is also the principle of positive reversal of the ratchet wrench.

One end of the elastic body 26 is received at the groove 27 of the toothing 19, and the toothing 19 is used to restrain the elastic body 26, and the other end of the elastic body 26 is placed at the restricting groove 28 of the steering knob 23, and the elastic body 26 is further The steering knob 23 is limited, so that the steering knob 23 can be pivoted at the third pocket 24 without being disengaged, and the steering knob 23 is provided with a ring groove 36, and a ring 37 is provided, and the ring 37 is accommodated in the ring In the groove 36, the ring 37 is further clamped on the inner circumferential surface of the third receiving groove 24, so that the steering knob 23 is pivoted at the third receiving groove 24 without being disengaged, and the turning button 23 is made of an elastic body. 26 and the limitation of the ring 37 are pivoted at the third pocket 24, which is the structure disclosed in the U.S. Patent.

However, the absence of the structure of U.S. Patent No. 2,957,377 is that, as shown in the fourth figure of the publication, the ring 37 is housed in the annular groove 36, but the ring 37 is only locked by friction. The inner peripheral surface of the three-receiving groove 24 is substantially restricted by the teeth 19 to limit the elastic body 26 and the elastic body 26 to restrict the steering knob 23, so that the steering knob 23 is pivoted at the third receiving groove 24, but when the ratchet wrench is operated Sometimes it is accidentally dropped to the ground. When the ratchet wrench is bumped, only two restriction structures are easy to disengage the steering knob 23 from the third pocket 24, so that the ratchet wrench cannot continue to rotate.

Another U.S. Patent No. 6,282,992, which is supplemented by the first and the ninth drawings, the ratchet wrench of the patent is also provided with basic components such as the body 12, the ratchet 72, the tooth 40, the steering knob 50 and the elastic body 92. The patent case further discloses a spring cap 90. The spring cap 90 is sleeved on the elastic body 92. One end of the spring cap 90 is received in the groove 42 of the tooth 40, and the other end of the spring cap 90 is received on the steering button. Within the limit slot 521 of 50.

The spring cap 90 is received in the recess 42 at one end, and the other end is received in the limiting slot 521, so that the steering knob 50 is pivotally disposed in the third receiving slot 15 without being disengaged. This is a U.S. Patent 6,282,992. The structure disclosed.

U.S. Patent 6,282,992 discloses a spring cap 90 such that the spring cap 90 is restrained by the teeth 40. The spring cap 90 limits the steering knob 50. When the ratchet wrench is slammed, there is only one restriction structure that easily disengages the steering knob 50. At the 15th slot, the ratchet wrench can not continue to rotate, and US Patent 6282992 and 2957377 have the same missing.
