Abstract
The invention discloses a wrench with replaceable heads. The wrench comprises a connecting handle and a plurality of wrenching heads. Holes are arranged on the wrenching heads and are matched with bolts and nuts in size. The upper surface of the connecting handle is provided with a fixing groove. A fixing shaft is arranged in the fixing groove. A clamp block is installed on the fixing shaft. Two sides of the front end of the clamp block are provided with convex lugs, and pin holes are arranged on the convex lugs. The rear end of the clamp block is provided with a cam-shaped fixing block, and a fixing hole throughout the fixing shaft is arranged on the fixing block. The convex lugs are located on two sides of the connecting handle, and two side faces of the connecting handle are provided with pins matched with the pin holes. The pin can freely extend on two sides of the connecting handle through poking blocks connected at the bottom of the connecting handle. The wrench with the replaceable heads is firm in connection, and wrenching head replacing operation is simple and convenient. The wrench is simple in structure and has low requirement for a manufacture process and materials, wrench weight can be effectively lightened, the wrench volume can be reduced, and manufacture cost of the wrench can be reduced.
Description
Technical field
The present invention relates to a kind of spanner, especially a kind of spanner that can change spanner belongs to the hardware ﹠ tools technical field.
Background technology
In maintenance with during the dismounting machine, usually can use all kinds of spanners, but because bolt, nut etc. exists Multiple Type big or small, also just have a variety of model sizes corresponding to the spanner that uses.At present, spanner is all generally complete sale, and be equipped with in each maintenance personal or enterprise be all from big to small a whole set of, spanner miscellaneous.Do not count like this instrument of other types in, just very large with regard to the weight and volume of the light complete set of wrench, if the maintenance personal will go out to carry, not only increased the weight of burden, and carried very inconvenient.For this reason, those skilled in the art have just invented a kind of head-replaceable wrench that is fixedly connected with by magnet, and it is mainly to realize the head of spanner and being fixedly connected with of handle by the suction of magnet.Although this spanner can reduce the weight and volume of the complete set of wrench to a certain extent,, this spanner is quite high in technique and the material requirements made, if magnet suction is too strong, spanner just is difficult to pull up and when changing Wrench head; If but the suction of magnet is not too strong, the head of its spanner is connected connection just built on the sand with handle.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of simple in structurely, easy to operate, and dismounting is easy to head-replaceable wrench.
Technical solution of the present invention is achieved in that a kind of head-replaceable wrench; Comprise connection handle and a plurality of spanner; All have trepanning on described spanner; Described trepanning matches with the size of bolt, nut; The upper surface of described connection handle has holddown groove; Be provided with fixed axis in described holddown groove; On described fixed axis, fixture block is installed; The front end both sides of described fixture block are provided with lug, and all have pin-and-hole on lug; Described fixture block rear end is provided with the fixed block of cam-like, and fixed block is provided with the fixing hole that runs through fixed axis; Described lug is positioned at the both sides of connection handle, and is equipped with the pin that matches with pin-and-hole on the two sides of connection handle; The shifting block of described pin by connection handle bottom can be at connection handle both sides free-extension.
Preferably, described holddown groove is two, is opened in respectively the two ends of connection handle.
Preferably, the trepanning on described spanner is two up and down that vary in size.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Head-replaceable wrench of the present invention adopts the cam pressing spanner on fixture block, and fixes fixture block by telescopic pin, and in the time of stable connection, spanner is when changing spanner, and operation is also very simple, convenient.The present invention program's head-replaceable wrench simple in structure is not high to the requirement of manufacture craft and material yet; And the trepanning of two kinds of model sizes that its spanner is provided with has just reduced the quantity of complete spanner, has effectively alleviated the weight of spanner, has reduced the volume of spanner, has reduced the cost of manufacture of spanner.
