Problems solved by technology

Therefore, such a design has the disadvantages of increased cost and slow processing speed
[0004] Moreover, this design of using springs and small steel balls to push the hexagonal holes does not really improve the slippage between the hexagonal surfaces and the hexagonal holes. The hexagonal wrench only has a single set of springs and small steel balls, so it can only provide a single surface. It has a better top setting effect, and the top setting of small steel balls cannot completely solve the lack of slippage
[0005] And the small steel ball is set on the hexagonal hole in the way of point contact. When the hexagonal wrench is used at a specific angle and tilted on the hexagonal hole, the small steel ball is likely to break away from the hexagonal hole, making it impossible for the small steel ball to top the hexagonal hole

Abstract

The invention discloses a spanner with a hexagonal ball end. A ball end is formed at one end of the spanner, can drive a to-be-driven member, is provided with a virtual working portion which can contact with the to-be-driven member, and comprises a first cambered surface. At least one concave portion and at least one meshed portion are formed on the first cambered surface; the concave portion is adjacent to the meshed portion which is in the same plane with the virtual working portion, and presents a concave shape relative to the virtual working portion; and the meshed portion can increase the friction between the ball end and the to-be-driven member.

Description

technical field [0001] The invention relates to a hexagonal wrench, in particular to a hexagonal ball-end wrench. Background technique [0002] refer to Figure 19 , is a schematic diagram of an existing hexagonal wrench. One end of the wrench 9 forms a ball head 91, and a ring neck 92 is formed on the inner peripheral surface adjacent to the ball head 91, wherein the outer circumference of the ball head 91 forms a hexagonal surface 93, and more than one of the hexagonal surfaces 93 An accommodation groove 94 is provided inwardly, the notch of the accommodation groove 94 is slightly smaller than the groove body, and a spring 95 and a small steel ball pushed by the spring 95 on the inside and the accommodation groove 94 is exposed on the outside are sequentially arranged from the inside to the outside. 96; the surface of the small steel ball 96 is smooth and can be elastically advanced. When the ball head 91 is inserted obliquely into the hexagonal hole of the screw lock, it...
