Description
Technical field
The present invention relates to a kind of assembly type hand-held tool, specifically a kind of assembly type hand-held tool that is applicable to any work post, band connection trousers and handle.
Background technology
The hand-held tool of tradition handle trousers structure is all generally tool body and the structure that is connected trousers and is integrated, handle for tool is flush-mounted in and connects in trousers, during with the assembling of wooden handle, with iron nail or pin, fix, use welding manner with the assembling of irony handle, and mould fine handle assembling and by cuff, tighten rivet and fix.Except the assembly connection with wooden handle, irony handle is large with the assembly connection difficulty of moulding fine handle, must in Shi factory, carry out, and for being not easy impaired irony handle and moulding fine handle, can not reuse is great waste.General as curved in the backhand of fork, spade, shovel being all located on tool body and link trousers, does not reach the not optimum state of unbalance loading, and people grasps equilibrium ratio and requires great effort when work, is not easy to use.Traditional-handwork Ju factory is just equipped with, and so not only can strengthen the volume taking up space, and unfavorable transportation and storage.The port edge expanded view that connects in addition trousers is the shape of falling ∨ pattern, in stample fiber, shearing stress can be produced uneven, the bending at the most advanced and sophisticated position of trousers is irregular, therefore cause connection trousers port not round and smooth, trouser legs have some setbacks, coordinate and just there will be imprecision with handle, thereby affect handle fitted pants, join firmness, easily get loose phenomenon.
At present, domestic had by connecting the structure that trousers and handle for tool be connected and fixed with connector, occur, but the connection trousers in this syndeton need to be made into separately semi-closed structure, with connector, connection trousers and handle are fixed together again, owing to connecting trousers, be semi-closed structure, not only manufacturing procedure is complicated, and connector is that one direction connects, cause connection trousers intensity low, affect the service life of instrument.
Summary of the invention
The present invention be directed to the various technical problems of mentioning in background technology, provide a kind of assemble simple, intensity is high, the assembly type hand-held tool of long service life.
The technical scheme that realizes the employing of foregoing invention object is: a kind of assembly type hand-held tool, comprise the connection trousers and the handle that are connected with hand-held tool body, on the sidewall of described connection trousers, be provided with main installing hole, connecting on trousers inwall and be provided with and stop into protruding, is smoothed curve structure after the port edge of connection trousers launches;
The end of described handle is provided with the tip of a branch and stops into recessed, is provided with secondary installing hole on the sidewall of handle one end;
The tip of a branch of described handle is inlaid in and connects in trousers, stops into recessed and matching with stopping into protruding.
Connecting trousers and hand-held tool body is Split type structure, and the two links together by connector.
Connecting trousers and hand-held tool body is structure as a whole.
Connect trousers port edge volume and after be a planar structure, connect trousers sidewall parallel with connection trousers central axis.
Handle is irony, mould the integrative-structure that the hard material such as fibre, injection moulding handle is made.
The backhand that is provided with mechanical compaction in the middle part of handle is curved, and circular arc most significant end and the distance between handle center's axis that backhand is curved are 2-8mm.
The main installing hole connecting on trousers comprises front square hole, side square hole and the slotted hole being separately positioned on three sidewalls that connection trousers are adjacent.
The tip of a branch that is arranged on handle end is truncated cone-shaped structure, stops into recessed and being arranged on the described tip of a branch.
Secondary installing hole is arranged on the rear of the described tip of a branch, and be in length and breadth 90 ° arranged in a crossed manner, its position is corresponding with the main installing hole on connection trousers.
The holding screw that assembly type hand-held tool is linked and packed, this holding screw and the corresponding installation of installing hole connecting on trousers, is characterized in that, it comprises the screw bolt and nut that forms holding screw, also comprises the packing ring being sleeved on screw rod; Described bolt is square neck bolt, and its head of a nail shape is corresponding with square opening place trousers outer margin arc-surface on connection trousers; Described nut is anti-return nut, and packing ring is the arcwall face corresponding with the trousers outer margin arc-surface of square opening opposite.
This assembly type hand-held tool disclosed in this invention, its connection trousers do not need independent processing, only need on existing connection trousers, process installing hole and stop into protruding, and manufacturing procedure is simple; Connect the type of attachment that trousers and handle junction adopt comprehensive formula, at the multi-direction connector that carries out, fix, connect the intensity of trousers and handle junction, extend tool life; The port edge that connects trousers is smooth curve structure, the sidewall that connects trousers is parallel with connection trousers central axis, it after port intervolves, is a plane, make the volume trousers process stress of making even, naturally reasonable, manufactured goods trouser legs are round and smooth, smooth and easy, tightly fit after guarantee connecting the moulding of trousers port with handle, make handle trousers connect firm, do not get loose; The curved design of backhand on handle, makes instrument unbalance loading not in use, laborsaving; This assembly type hand-held tool is applicable to the instrument of any work post to improve, and easy to assemble, tool body and handle can be packed respectively, transport, store, and saves space, cost-saving.
