Abstract

The invention discloses an adjustable internal hexagonal wrench. The adjustable internal hexagonal wrench comprises a supporting cylinder, clamping grooves, rotating handles, buckles, a top hole, a bottom hole, top threads, a propelling pin, a round handle, a compression spring and a thread rotating body, wherein the two clamping grooves which are symmetrical in position are formed in the outer wall of the supporting cylinder, the rotating handles are hinged to the bottoms of the clamping grooves, the buckles are integrally formed on the top surfaces of the clamping grooves, the buckles are ofsemi-sphere structures, the tail ends of the rotating handles are buckled to the top surfaces of the clamping grooves through the buckles, the top hole and the bottom hole are formed in the supporting cylinder from top to bottom, the inner diameter of the bottom hole is smaller than the inner diameter of the top hole, the top threads are in threaded connection with the top hole, the propelling pin is in sliding connection with the bottom hole in an up-and-down sliding mode, the round handle is integrally formed at the top of the propelling pin, a cone is integrally formed at the bottom of thepropelling pin, the round handle is in up-and-down sliding connection with the inner wall of the top hole, and the compression spring is connected to the outer wall, at the top of the round handle, of the propelling pin in a sleeving mode. The adjustable internal hexagonal wrench is capable of meeting the using requirement of internal hexagonal bolts of different specifications in a stretchable mode, convenient to adjust, easy to stress and small in occupied space.

Description

technical field [0001] The invention relates to an inner hexagonal wrench, in particular to an adjustable inner hexagonal wrench. Background technique [0002] The Allen wrench is also called the Allen wrench. It exerts force on the screw through the torque, which greatly reduces the force intensity of the user. It is an indispensable and powerful tool in the industrial manufacturing industry. When the commonly used hexagonal wrench disassembles and assembles the hexagonal bolt, it is necessary to choose among wrenches of various specifications, and it is inconvenient to carry, easy to lose, and takes up a lot of space. Contents of the invention [0003] The object of the present invention is to provide an adjustable inner hexagonal wrench to solve the above technical problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An adjustable inner hexagonal wrench, including a support cylinder, a card slot, a ha...
