Abstract

A socket wrench with a foldable handle is characterized in that the wrench head is provided with a ratchet mechanism and a hexagonal through hole in the middle, and is provided with a sleeve with a hexagonal prism; one end of a wrench rod is connected with the wrench head while the other end thereof takes the shape of a ball, and both edges of the wrench rod are sliced off; a through hole is formed in the middle; counter bores are respectively formed on the upper spherical face, the middle spherical face and the lower spherical face; a through groove formed at one end of a wrench handle and the spherical face end of the wrench rod are matched with each other and connected by a short shaft; the upper casing of the wrench handle is fixed through nuts; an end cover is arranged at the end of the wrench handle and connected with the casing through threads; counter bores are formed in the wrench handle; springs and lock levers are mounted in the counter bores; the springs are arranged at the bottoms of the counter bores and above and below the lock levers; two slip sheets are arranged on two sides of the wrench handle and connected through the slotted holes penetrating the wrench handle and small shafts of the through holes of the lock levers; and the lower ends of the lock levers are matched with the counter bores on the spherical face of the wrench rod. The lock levers move upwards when the slip sheets are pushed, so as to release the counter bores; and the wrench handle can be folded into a right angle and used conveniently, thereby improving the working efficiency greatly.

Description

The folding box spanner of handgrip

Technical field

The utility model belongs to the folding box spanner of handgrip of hardware ﹠ tools class.

Background technology

Spanner is used for screwing or unscrewing bolt when being the dismounting machine, a kind of instrument of nut etc., commonly used have a single-end spanner, double (end) wrench, adjustable wrench, box spanner etc., these spanners have a common characteristic, be that handgrip length is all fixed, and when the dismounting machine, in order to screw or unscrew bolt, nut, tend to be subjected to bolt in its operating process, the restriction of fixed by nut position, use the space of spanner to be met, this is rotatable once the bolt that encloses or two circles screw or unscrew, nut must make segmentation bit by bit into and slowly rotate and finish, and so promptly wastes time and energy, operating efficiency also can't be improved, so need be improved.

The utility model content

The purpose of this utility model provides the easily folding box spanner of handgrip fast of a kind of operation flexible and convenient to use.

The technical solution of the utility model is to fixedly connected with wrenching bar at the socket head of band ratchet mechanism, the box spanner centriciput has six square tube holes and cooperates with the sleeve that has hexagonal prism, the other end of wrenching bar is a spheroidal, but scabble on both sides, the middle part is provided with a through hole, on the sphere, in, following three parts respectively is provided with a counterbore, spanner has groove to an end and cooperates with wrenching bar ball face end, connect with minor axis, spanner is fixed upper case by nut, the termination has end cap to be connected with outer casing screw, is provided with counterbore in the spanner handle, is equipped with spring and locking bar in the counterbore, counterbore bottom peace spring, spring cooperates with the locking bar upper end, and locking bar bottom spanner is provided with two slide plates to the both sides, and two slide plates connect the little axle of through hole on last slotted eye and the locking bar by passing spanner, promote slide plate like this and just can drive locking bar, the locking bar lower end cooperates with counterbore on the wrenching bar ball face, and spanner is just rolling over the location, the convenient use like this.

The utility model has the advantages that: can use equally with general box spanner, can after being converted into the right angle, do the rotation use as required again simultaneously to spanner, can not be subjected to the influence of bolt, fixed by nut position when so not only operating, and use more conveniently, laborsaving, its operating efficiency also can improve greatly.
