Twisting structure for ratchet wheel screwdriver grip

Abstract

The ratchet screwdriver handgrip torsion structure comprises No.1 and No.2 handles and a positioning device, the said No.1 handle having one end for spanning, the other end forming into a jointing section, the said No.2 handle forming into a combining section pivoted at the joint section of No.1 handle, allowing No.2 handle twisting within No.1 and No.2 positions, and the said positioning device between No.1 and No.2 handles to provide torsion positioning relations between the two handles. When the No.2 handle locates at No.1 position, it is at the same axle with the No.1 handle, while the No.2 handle locates at the No.2 position, it keeps an angular separation with the No.1 handle to extend the torsion arm.

Description

technical field [0001] The invention relates to a twisting structure of a handle of a ratchet screwdriver, in particular to a twisting structure of a handle of a ratchet screwdriver to extend the force arm by means of twisting. Background technique [0002] Please refer to Taiwan Patent Publication No. 566286 for a patent case for a tool handle with a rotatable angle, which includes a handle 10 , a joint 20 and a pin 30 . One end of the handle 10 is formed with an opening-shaped assembly groove 12, and one end of the joint 20 is formed with a semicircular extension plate 24, and the extension plate 24 is pivoted on the said The handle 10 is installed in the assembly slot 12 so that the handle 10 can be turned at an angle relative to the joint 20 . A channel 26 with a concave portion 264 is defined in the extension plate 24 . The snap pin 30 penetrates the wall of the assembly groove 12 of the handle 10 and extends into the channel 26 of the extension plate 24 , and is posi...

AI Technical Summary

Problems solved by technology

The unevenness produced on the outer surface of the overall tool handle 90 not only makes the appearance design less beautiful, but also is not conducive to the user's grip, that is, it is difficult for the user to have a good grip and construction effect.

[0008] Also existing tool handle 90 is in order to sleeve C buckle on projection 913, so opened a through hole 923, and puts a plug 924 on through hole 923, so complicated design is more unsuitable for industrial utilization, wastes cost and working hours

And when in use, the plug 924 is likely to come out of the through hole 923 or fall due to the force applied by the user or other factors, which will cause the disadvantage that the through hole 923 is easy to accumulate dust and affect its pivoting effect. or positioning effects
