Abstract

The utility model provides a ratchet gear comprising a control body, a ratchet body and a switch body, wherein a shaft hole is formed in the control body; accommodating grooves which are communicated with one another and have equal angles are formed on the top surface of the control body; a group of clip blocks and an elastic element are arranged in each accommodating groove; ratchet teeth are arranged on the outer ring surface of the ratchet body; a drive part is arranged at one end of the ratchet body; the drive part extends out of the shaft hole in the control body in a penetrating way to enable the ratchet teeth to be meshed with the three groups of clip blocks; the switch body is assembled on the control body; and at least three shift parts capable of controlling the three groups of clip blocks are arranged on the bottom surface of the switch body. Therefore, the ratchet teeth of the ratchet body can be clipped in the clipping way of the three groups of clip blocks with equal angles, so as to improve the clip strength and stability and further improve the operation torsion; and more operation angle selections can be achieved by increasing the number of the ratchet teeth, so as to achieve the practical benefit of greatly promoting the use efficiency.

Description

Ratchet device

Technical field

The utility model relates to a kind of Wrench, and particularly a kind of three groups of clipping block stopper modes utilizing the isogonism configuration are selected to improve operation torsion more and to increase work angle, and significantly promotes the ratchet device of effective utilization.

Background technology

Instrument with ratchet device, its overriding concern be the torque magnitude that can bear, and torque magnitude depends on the clip joggled strength of hook tooth and clipping block, yet, select the instrument of the hook tooth of the less number of teeth for use, though preferable torsion can be provided, but in application of force operation, be difficult for obtaining preferable work angle, and select the instrument of the hook tooth of the more number of teeth for use, though easily obtain preferable work angle, but reduce the torsion of operation, therefore, how to make instrument can have preferable operation torsion and work angle reality concurrently when important with ratchet device.

See also Fig. 1, it is No. the 91220384th, TaiWan, China " improved structure of the forward and reverse ratchet of lever " patent case, it is provided with the ratchet body 11 that an inner ring surface has hook tooth 111, for clipping block 13A of assembling with two rotatable beats, the control body 12 of 13B, control body 12 and push against clipping block 13A with spring 14, the hook tooth 111 engagement stoppers of 13B and ratchet body 11, other is provided with a switching that turns to that is placed on control body 12 outsides and encircles (scheming not shown), being used for controlling clipping block 13A or clipping block 13B rotation contracts in the beat and breaks away from hook tooth 111, to switch application of force direction, when turning to switching ring control clipping block 13B to be engaged in the hook tooth 111 of ratchet body 11, control body 12 can utilize clipping block 13B drive ratchet body 11 to do dextrorotation then application of force operation, when control body 12 is rotated counterclockwise, the start of then can dallying, and can adjust work angle.But this ratchet structure is adopted single clipping block stopper ratchet body, so that the torsion deficiency, if increase the number of teeth of hook tooth, more can significantly reduce stopper mesh degree, the situation that causes stopper to skid.

See also Fig. 2, be No. 92216291 " ratchet device of disymmetry stopper " patent case of TaiWan, China, its axis hole 211 outsides at a control body 21 are provided with the arcuation conduit 212A of two groups of symmetries, 212B, 213A, 213B, each
