Embodiment Construction

[0015] Attached below figure 1 , attached figure 2 The present invention will be further described.

[0016] as attached figure 1 As shown, the multifunctional wrench includes a fixed handle 2, a movable handle 1 movably inserted in the fixed handle 2, and a locking device for locking the movable handle 1 relative to the fixed handle 2. The head end of the movable handle 1 A hexagonal slot is formed with the head end of the fixed handle 2 and an opening 3 is provided outside the hexagonal slot. When in use, loosen the locking device and pull out the movable handle 1, then insert the bolt head or nut from the opening 3 into the hexagonal slot and put the head end of the fixed handle 2 against the bolt head or nut, Push the fixed handle 2, the movable handle 1 can slide inward along the fixed handle 2, and finally the hexagonal slot formed by the head end of the movable handle 1 and the head end of the fixed handle 2 will clamp the bolt head or the nut tightly, and the lock ...

Abstract

The invention relates to a multifunctional spanner which comprises a fixed handle, a movable handle and a locking device. The movable handle is movably inserted into the fixed handle. The locking device is used for locking the movable handle relative to the fixed handle. The head end of the movable handle and the head end of the fixed handle form a hexagonal clamp groove. An opening is formed on the outer side of the hexagonal clamp groove. A bolt head or nut enters into the hexagonal clamp groove from the opening to allow the head end of the fixed handle to be abutted against the bolt head or the nut. The fixed handle is pushed inwardly and then the movable handle can slide inwardly along the fixed handle, the hexagonal clamp groove clamps the bolt head and the nut, the locking device locks the movable handle, and demounting with the spanner can be performed. Due to the fact that the movable handle is adjustable, bolts or nuts of different specifications can be adapted to. The multifunctional spanner is applicable to axial bolt and nuts and planar bolts and nuts and has the same use effect as a box spanner.

Description

technical field [0001] The invention relates to a hardware tool, in particular to a wrench. Background technique [0002] At present, the wrenches used in automobile maintenance are mainly divided into open-end wrenches, ring wrenches and adjustable wrenches for size adjustment. The existing open-end wrench and the adjustable wrench for adjusting the size are used for dismantling the bolts of the axially connected pipe fittings, and can also be used for dismantling the flat bolts. The ring wrench can only be used for the disassembly of the flat bolts. Practical problems, open-end wrench and adjustable wrench to adjust the size to disassemble the bolts of axially connected pipe fittings, easy to slip off and damage the flat surface of the nut, and the ring wrench is not easy to slip off and damage the flat surface of the nut, but it can only be used for flat bolt removal. When dismantling the car repair, it is also necessary to use eyes to judge whether the bolt is an axial ...
