Problems solved by technology

[0003] At present, most of the screw removal wrenches are mostly aimed at dismantling the hexagonal screws without damage. The traditional wrench mainly uses the apex of the end face of the hexagonal screw to bear the force. When disassembling and rotating, it is easy to cause damage and deformation of the edge of the hexagonal screw, resulting in The hexagonal screw cannot be disassembled, and the quick release effect of the hexagonal screw cannot be achieved

Embodiment 1

[0043] Such as Figure 4 As shown, the rotary assembly 24 includes a ball head 241 arranged on the inner wall of the contact 22. The ball head 241 is embedded and movably connected with the ball groove 242 provided on the end surface of the handle 2. When the contact 22 touches the end surface of the hexagonal screw, Continue to turn the handle 2, and now the handle 2 will constantly move in the chuck 1, and the rotational driving force generated by the handle 2 to the contact 22 will be transmitted to the ball head 241, so that the ball head 241 will move on the ball head 241. Rotating in the slot 242 can convert the rotational driving force of the handle 2 into a linear driving force, and continue to drive the contact 22 and the end surface of the hexagonal screw to tighten, thereby increasing the contact area between the contact 22 and the hexagonal screw, and preventing the wrench from disassembling the hexagonal screw. The phenomenon of falling off when screwing.

Embodiment 2

[0045] Such as Figure 5 As shown, the rotary assembly 24 includes a collar 243 arranged on the contact 22, the inner wall of the collar 243 is adapted to the outer wall of the sleeve post 244 on the end surface of the handle 2, and the inner wall of the collar 243 is provided with a rolling groove 2431, The outer wall of the sleeve 244 is embedded with a ball 2441, and the sleeve 244 is connected to the collar 243 through the embedded rolling of the ball 2441 and the rolling groove 2431;

[0046] When the contact 22 touches the end face of the hexagonal screw, continue to turn the handle 2, and now the handle 2 will continuously move into the chuck 1, and the rotational driving force generated by the handle 2 to the contact 22 will be transmitted to On the sleeve 244, the ball 2441 is rolled in the rolling groove 2431, so that the rotational driving force of the handle 2 can be converted into a linear driving force, and the contact 22 is continuously driven to tighten with th...

Abstract

The invention discloses a universal wrench for disassembling operation. The universal wrench comprises a chuck and a grip, wherein a screw hole is formed in the chuck, and the screw hole is in threaded connection with a thread at one end of the grip; and a rotating assembly which rotates in the axial direction of the grip or rotates in a hemisphere shape is arranged on the end surface of the grip,and a contact which is in contact with the end surface of a hexagonal screw is arranged on the rotating assembly. According to the universal wrench, the universal wrench adopts a split type structural design, so that the use effect of flexible and convenient disassembly and assembly operation can be achieved, and the operability of the wrench is improved; and when the hexagonal screw is twisted,the contact area and the friction resistance of the contact to the end surface of the hexagonal screw are increased by combining the rotating action of the rotating assembly, so that the universal wrench can be used for bearing force on the two parallel end surfaces of the hexagonal screw, the problem that the edge of the screw is deformed due to external force damage can be solved, and the quickdisassembly effect of the damaged hexagonal screw is achieved.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to a universal wrench used for disassembly operations. Background technique [0002] A wrench is a commonly used installation and disassembly tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other threaded openings or hole fasteners that hold bolts or nuts. Wrenches are usually made of carbon or alloy materials. Made of steel, the wrench is usually made with an opening or a sleeve hole for clamping bolts or nuts at one or both ends of the handle. When using, an external force is applied to the handle along the direction of thread rotation to twist the bolts or nuts. During disassembly and assembly, it is also necessary to use a wrench to disassemble the hexagonal screws. [0003] At present, most of the screw removal wrenches are mostly aimed at dismantling the hexagonal screws without damage. The traditional wrench mainly uses the apex...
