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
The present invention relates to a kind of hardware ﹠ tools, be specifically related to a kind of spanner.
Background technology
The spanner that uses during at present auto repair mainly is divided into the pattern spanner alive of open-end wrench, double offset ring spanner and adjustment size.The monkey wrench of existing open-end wrench and adjustment size, being used for axial connecting tube sieve bolt disassembles, also can be used for plane sieve bolt disassembles, double offset ring spanner can only be used for plane sieve bolt dismounting, there is insurmountable practical problem separately in three kinds of spanners, and the monkey wrench of open-end wrench and adjustment size is disassembled axial connecting tube bolt, easily slippage and damage nut plane problem, double offset ring spanner is difficult for slippage and damages the nut plane problem, but can only be used for the plane Bolt dismantling.When motor vehicle repair is disassembled, also need to judge that with sight bolt is axial connecting tube bolt or plane bolt, select again spanner corresponding to dimension size.
Summary of the invention
The present invention is in order to overcome the deficiency of above technology, and a kind of multifunctional wrench that axial bolts, plane bolt can be adjusted size that is applicable to is provided.
The present invention overcomes the technical scheme that its technical problem adopts:
This multifunctional wrench, comprise the locking device that fixed handle, activity are plugged in the movable handle in the fixed handle and are used for movable handle is locked with respect to fixed handle, the head end of described movable handle and the head end of fixed handle form a hexagonal draw-in groove and in hexagonal draw-in groove arranged outside one opening are arranged.
Above-mentioned locking device comprises the some rectangle draw-in grooves that are arranged on the movable handle, be slidingly mounted on the fixture block on the fixed handle, what be arranged at the fixed handle outside arranges reeded locking cap and spring, the size of the appearance and size of described fixture block and rectangle draw-in groove is complementary, described fastening block part add-drop is in the rectangle draw-in groove, one end of described spring is arranged in the groove of locking cap, its other end contacts with fixture block, one side of described fixture block is equipped with projection, described projection is slidingly mounted in the fixed handle along the direction of motion of fixture block, and the distance between described per two adjacent rectangle draw-in grooves is complementary with the external diameter of the nut of two adjacent-specifications or bolt head is poor.
Above-mentioned locking device comprises the some zigzag draw-in grooves that are arranged on the movable handle, be slidingly mounted on the fixture block on the fixed handle, what be arranged at the fixed handle outside arranges reeded locking cap and spring, the head end of described fixture block is provided with the inclined-plane that parallels with inclined plane in the zigzag draw-in groove, described fastening block part add-drop is in the zigzag draw-in groove, one end of described spring is arranged in the groove of locking cap, its other end contacts with fixture block, one side of described fixture block is equipped with projection, described projection is slidingly mounted in the fixed handle along the direction of motion of fixture block, and the distance between described per two adjacent zigzag draw-in grooves is complementary with the external diameter of the nut of two adjacent-specifications or bolt head is poor.
For laborsaving, the opening of above-mentioned hexagonal draw-in groove towards with the fixed handle length direction layout that meets at right angles.
The invention has the beneficial effects as follows: unclamp locking device during use movable handle is pulled out, afterwards bolt head or nut are entered the hexagonal draw-in groove and the head end of fixed handle is resisted against on bolt head or the nut from opening part, inwardly promote fixed handle, movable handle can inwardly slide along fixed handle, the head end of final movable handle and the acrogenous hexagonal draw-in groove of fixed handle are with bolt head or nut chucking, and this moment is with fixing can the dismounting by spanner of locking device locking realization movable handle.Because movable handle is adjustable, therefore go for bolt or the nut of different size.Nut bolt on this multifunctional wrench is not only applicable to is axially avoided it to use open-end wrench to be difficult for slippage and damage nut plane problem, and is equally applicable to the bolt and nut of plan-position, and result of use is identical with double offset ring spanner.
