[summary of the invention]

In order to overcome the deficiency in background technology, the present invention discloses the replaceable bayonet socket combination wrenches of a kind of explosion-proof slow-witted plum, by the different size bayonet socket of a plurality of " U " shape plug connector and the different size bayonet socket of a plurality of embedding external members, when having realized operation, number of tools effectively alleviates.

For achieving the above object, the present invention adopts following technical scheme:

The replaceable bayonet socket combination wrenches of a kind of explosion-proof slow-witted plum, comprise handle, openend, " U " shape plug connector, plum Hua Duan and embed external member, openend and plum Hua Duan are separately positioned on the two ends of handle, described openend has a socket, be respectively equipped with groove on the two side of socket, the described groove of the raised line that " U " shape plug connector both sides outer wall arranges and socket is pegged graft, and " U " shape plug connector is a plurality of, and the bayonet socket of a plurality of described " U " shape plug connector is respectively different size; Be provided with loading port on plum Hua Duan, loading port upper port wall is inner toothed surface, the lower ports wall of described loading port is inner headed face, the outer edge surface top that embeds external member is provided with the outer flank of tooth, the outer edge surface bottom of described embedding external member is periphery, is provided with rubber ring on the periphery that embeds external member, the outer edge surface of described embedding external member and loading port grafting, it is a plurality of embedding external member, and the magnificent shape running-on of the plum of a plurality of described embedding external members is respectively different size.

The replaceable bayonet socket combination wrenches of described explosion-proof slow-witted plum is respectively equipped with rubber layer in the groove of socket both sides.

The replaceable bayonet socket combination wrenches of described explosion-proof slow-witted plum, the inner toothed surface of the loading port upper port wall that arranges on plum Hua Duan and the inner headed face of lower ports wall are step transition.

Owing to adopting technical scheme as above, the present invention has following beneficial effect:

The replaceable bayonet socket combination wrenches of explosion-proof slow-witted plum of the present invention, utilize aluminium bronze or beryllium-bronze as making material, different size bayonet socket by a plurality of " U " shape plug connector coordinates with the socket of openend, the different size bayonet socket of a plurality of embedding external members coordinates with the loading port of plum Hua Duan, the drawback that effectively alleviates of number of tools when having realized operation, the present invention has the advantages such as simple to operate, easy to carry.
