Abstract

The invention discloses an adjustable socket wrench, which comprises a hexagonal cutting sleeve, a handle, a threaded sleeve, a rotating shaft and an anvil. When the bolt is dismounted, the bolt head is sleeved by the hexagonal clamping sleeve, the threaded sleeve is rotated clockwise, the movable socket wrench is reduced, the threaded sleeve drives the rotating shaft and the pressing anvil to rotate clockwise and generate upward axial movement, the pressing anvil is screwed out of an upper round hole in the bottom edge of the hexagonal clamping sleeve, and when the pressing anvil abuts against the bolt head, three edges of the bolt head are firmly clamped inside the hexagonal clamping sleeve, so that the bolt can be dismounted; conversely, the movable socket wrench is enlarged by rotating the movable threaded sleeve counterclockwise, and the threaded sleeve drives the rotating shaft and the anvil to rotate counterclockwise and generate downward axial movement. In the operation process of constructors, the movable socket wrench can firmly clamp the nut or the bolt head, and the phenomenon of slipping or loosening can be effectively avoided.

Description

Adjustable socket wrench

Technical Field

The invention relates to the technical field of adjustable wrenches.

Background

As a common mounting and dismounting tool, the wrench can be used for screwing bolts, screws, nuts and the like and can be used for fastening and loosening nuts and bolts with different specifications. The adjustable spanner can be adjusted in a certain range because of its opening, and convenient to use so use extensively, but exert oneself too greatly when using the spanner and can cause the edges and corners of nut to warp to take place to skid easily or the pine takes off the phenomenon and even bumps and injures the staff, causes injury accident and loss of property.

Disclosure of Invention

The purpose of the invention is as follows: the special structure of the invention can firmly clamp three edges of a hexagon nut or a bolt head in the movable sleeve, and can effectively avoid the phenomenon of slipping or loosening.

The technical scheme is as follows: in order to achieve the technical purpose and achieve the technical effects, the invention is realized by the following technical scheme.

An adjustable socket wrench comprises a hexagonal cutting sleeve, a handle, a threaded sleeve, a rotating shaft and an anvil; the bottom edge of the hexagonal cutting sleeve is provided with an upper round hole and a lower round hole; the handle is cylindrical and is arranged at the lower end of the hexagonal cutting sleeve, external threads are arranged at the lower part of the handle, and a cylindrical through hole is axially formed in the center of the interior of the handle; the inner part of the threaded sleeve is provided with internal threads, and the threaded sleeve is installed at the lower part of the handle through threaded connection; one end of the rotating shaft is connected with the threaded sleeve together by welding, and the other end of the rotating shaft is provided with an external thread; the anvil is cylindrical and is provided with an internal thread hole and is installed on the rotating shaft through threaded connection.

The diameter of the upper round hole at the bottom edge of the hexagonal cutting sleeve is 0.5mm larger than that of the anvil.

The diameter of the lower round hole at the bottom edge of the hexagonal cutting sleeve is 0.5mm larger than that of the rotating shaft.

The diameter of the cylindrical through hole in the handle is 0.5mm larger than that of the rotating shaft.

The height of the anvil is consistent with the depth of the upper round hole at the bottom edge of the hexagonal cutting sleeve.

The upper round hole on the bottom side of the hexagonal cutting sleeve, the lower round hole on the bottom side of the hexagonal cutting sleeve, the cylindrical through hole of the handle, the rotating shaft and the center line of the anvil are overlapped.

Has the advantages that: simple structure, adjustable size can effectively avoid the phenomenon of skidding.

Detailed Description

An adjustable socket wrench comprises a hexagonal cutting sleeve 1, a handle 2, a threaded sleeve 3, a rotating shaft 4 and an anvil 5. There are two round holes bottom hexagonal cutting ferrule 1, the diameter of going up round hole 8 is 1mm bigger than the diameter of anvil 5, the diameter of lower round hole 9 is unanimous with the diameter size of handle through-hole 10, handle 2 is cylindrical in the lower part of hexagonal cutting ferrule 1, 2 lower extremes of handle have external screw thread 6, the diameter of handle through-hole 10 is 1mm bigger than the diameter of axis of rotation 4, the inside internal thread 7 that has of threaded sleeve 3 is same size with external screw thread 6 of handle lower extreme, threaded sleeve 3 passes through threaded connection and installs the lower extreme at handle 2, 4 one end of axis of rotation be in the same place through welded connection with threaded sleeve 3, the other end has the external screw thread to be used for installing anvil 5, anvil 5 be cylindrical, have the internal thread, install on axis of rotation 4 through threaded connection, the height of anvil 5 is unanimous with the degree of.

When the disassembly and assembly work is carried out, the bolt head 11 is sleeved with the hexagonal cutting sleeve 1, the threaded sleeve 3 is rotated clockwise, the movable socket wrench is reduced, the threaded sleeve 3 drives the rotating shaft 4 and the anvil 5 to rotate clockwise and generate upward axial movement, the anvil 5 is screwed out of the upper round hole 8 in the bottom edge of the hexagonal cutting sleeve, when the anvil 5 tightly pushes against the bolt head 11, three edges of the bolt head 11 are firmly clamped in the hexagonal cutting sleeve 1, and the bolt can be disassembled and assembled; conversely, when the threaded sleeve 3 is rotated counterclockwise to turn up the adjustable socket wrench, the threaded sleeve 3 drives the rotating shaft 4 and the anvil 5 to rotate counterclockwise and to move axially downward. In the operation process of constructors, the movable socket wrench can firmly clamp the nut or the bolt head, and the phenomenon of slipping or loosening can be effectively avoided.
