Problems solved by technology

[0004] The above-mentioned screwdriver structure only has two lengths available for use. For users, it lacks the convenience of using more variety of lengths to choose from.
Moreover, when the user turns the screwdriver, he often applies a large axial thrust due to carelessness, causing the steel ball 622 originally positioned in the upper groove 72 to slide to the lower groove 73 due to compression, Therefore, it has a considerable impact on the safety of the user's operation of the screwdriver.

Abstract

The invention relates to an adjustable screw driver structure, which comprises a rod, a clamper and a handle, wherein one end of rod is screw driving head, another end is sheathing section; the clamper comprises rod, flexible element and compression element; the rod has a container with an axial groove with two blocks, to divide the rod into two elastic sheets, and its inner edge has a clamping section, and its open end has an outer screw section; the flexible element is through the container to contact the bottom of container; two blocks are through two open grooves of rod; the rod sheathing section is through the container; when compression element is screwed with rod, the elastic sheets will be bended inwards, to make clamping section clamp the stop section of rod; the rod is fixed to one axial hole of handle. The invention can improve safety.

Description

technical field [0001] The invention relates to an adjustable screwdriver structure. Background technique [0002] Such as image 3 As shown, it is an existing screwdriver structure, which includes a rod body 6 and a handle 7. The handle 7 has an accommodating space 71, and the accommodating space 71 has two upper and lower grooves 72, 73 on the inner wall. One end of the rod body 6 is a cross screwdriver head 61 for use, and the end of the rod body 6 away from the cross screwdriver head 61 has an alcove 62 on the periphery, and the alcove 62 is equipped with an elastic component 621 and a steel ball for positioning 622. [0003] When the user intends to use it, the steel ball 622 must first be pressed into the alcove 62 and then the rod body 6 is placed into the accommodating space 71 for sliding. When the steel ball 622 slides to the upper groove 72 of the accommodating space 71 of the handle 7 , it pops up and is positioned against the upper groove 72 . If the rod body...
