Description
Technical field
The utility model belongs to the hand-operated tools that operation is used, particularly a kind of combined screwdriver.
Background technology
At present in practical application: the kind of screwdriver is a lot, as following several kinds:
1, a handle cutter head is arranged.This shortcoming is that each screwdriver is exactly a kind of specification, and uses unicity, so will have a plurality of screwdrivers at work.
2, a handle bull is also arranged, a plurality of cutter heads and a handle are adorned a box.The shortcoming of this screwdriver is when using the driver bit of different size, take off another cutter head at every turn, and this in addition handle and cutter head separation case also make cutter head lose easily.
The utility model content
The technical problem that the utility model will solve provides a kind of combined screwdriver simple in structure, with low cost, multiple functional, easy to carry.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of combined screwdriver comprises handle, handle of a knife and cutter head; Outer surface at said handle is evenly equipped with the container slot that holds handle of a knife and cutter head of extending along its axis direction; Be provided with the ring-type hinge coaxial with it on the top of handle, an end of said handle of a knife is connected with cutter head, and its other end is connected with the ring-type hinge through the hinge of " L " type, is provided with stopping means in the junction of said ring-type hinge and hinge; The distance that the central axis of said handle of a knife and cutter head and the tie point of ring-type hinge and hinge belong to vertical straight line and this vertical straight line equate with the distance of handle center's axis.
Said stopping means is limit spring or banking stop.
Said container slot is 8.
The technological progress of adopting technique scheme to obtain is: the utility model is simple in structure, and is easy to make, with low cost, and has the driver bit of multiple model, multiple functional, and service efficiency is high; The utility model volume is less, is easy to carry; When using the utility model construction, when needing the screwdriver of different model, need not dismantle, change cutter head, save the engineering time, improve efficiency of construction.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1, cutter head, 2, hinge, 3, container slot, 4, handle of a knife, 5, the ring-type hinge, 6, handle.
The specific embodiment
By shown in Figure 1 knowing, combined screwdriver comprises handle 6, handle of a knife 4 and cutter head 1; Outer surface at said handle 6 is evenly equipped with the container slot 3 that holds handle of a knife 4 and cutter head 1 of extending along its axis direction; Be provided with the ring-type hinge 5 coaxial with it on the top of handle 6, an end of said handle of a knife 4 is connected with cutter head 1, and its other end is connected with ring-type hinge 5 through the hinge 2 of " L " type, is provided with stopping means in the junction of said ring-type hinge 5 and hinge 2; Said handle of a knife 4 equates with the distance of this vertical straight line with handle 6 central axis with the distance that the tie point of ring-type hinge 5 and hinge 2 belongs to vertical straight line with the central axis of cutter head 1; Said stopping means is a limit spring; Said container slot 3 is 8.
The method for using of the utility model: when using the utility model construction,, select the cutter head 1 of suitable types at first according to the nut model that will operate; This cutter head 1 is pulled out from container slot 3 with handle of a knife 4; Because the ring-type hinge 5 of handle of a knife 4 one ends and handle 6 upper ends is hinged, cutter head 1 and handle of a knife 4 are under the effect of the hinge 2 of " L " type, with the common screwdriver of handle 6 combined formation like this; And the central axis of cutter head 1, handle of a knife 4 and handle 6 coincides at this moment, so just can use.
The position that on ring-type hinge 5, with hinge 2, is hinged is provided with limit spring, when the central axis of the central axis of cutter head 1 and handle of a knife 4 and handle 6 coincides, can cutter head 1 and handle of a knife 4 be fixed like this.Stopping means can also be for banking stop etc., as long as serve the same role.
The utility model is provided with the cutter head 1 of the screwdriver of 8 different models, and a word is arranged, and cross also can be arranged, and big ting model has nothing in common with each other, and selects the suitable model to get final product during use as required.During use, only needed cutter head 1 and handle of a knife 4 are pulled out, form screwdrivers with handle 6, the cutter head 1 of all the other 7 models and handle of a knife 4 still folding with handle 6 on container slot 3 in form whole with handle 6.
