Description

A kind of quick double-handle multifunctional screw driver
Technical field
The utility model relates to the quick double-handle multifunctional screw driver of a kind of electrician of being used for and mechanical engineering field, belongs to electrician and machine tool.
Background technology
At present, screwdriver is one of instrument commonly used such as machinery, electrician, family.Exhausted most screwdriver is single size or shape, and common cross or Flathead screwdriver are made up of handle, bar and cutting edge, and screwdriver has only the screw of the model that is complementary with it just to tighten or unscrew during use.Hand need go back to original position again and can finish the tightening or unscrew an of screw, big, the inefficiency of labour intensity through repeatedly unclamping during work, only is suitable for a kind of screw of model simultaneously, uses very inconvenient.
Summary of the invention
The purpose of this utility model is: in order to tighten or unscrew screw fast, save the working time, increase work efficiency; With the screw of tool changing head with suitable different model, have multiple function simultaneously, in addition for the screw that has spring, can keep constant substantially normal pressure, avoid counter-rotating, the spy provides a kind of quick double-handle multifunctional screw driver.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of quick double-handle multifunctional screw driver, be made up of cutter head, knurling handle, Square handle, ratchet, ratchet, its architectural feature is: cutter head is installed on the knurling handle, is a square hole in the knurling handle; Knurling handle is connected with two-way click structure, and the ratchet and pawl of packing in Square handle, ratchet and ratchet are two-way engagement; The Square handle cross section is rectangular, is provided with connecting rod in the Square handle, and connecting rod one end is connected with knurling handle, and the other end is installed nut.Cutter head has the polytype of different model, comprises a kind of of in-line cutter head, cross cutter head, Allen wrench or outer-hexagonal wrench.
The design of this screwdriver has two-way click structure, and Square handle rotates counterclockwise, click engagement carrying out work; Square handle clockwise rotates, and click no longer meshes, and realizes that driver goes back to original position.If ratchet is changed a direction, carry out work when Square handle clockwise rotates, otherwise driver goes back to original position.
The utility model has following beneficial effect compared with the prior art: in (1) this screwdriver the click structure being housed can shorten working hours, and increases work efficiency; (2) to having the screw particularly suitable of spring; (3) simple in structure, cost is low, interchangeable bit, has multiple function, is the standing screwdriver that is used for machinery, electrician, family, is fit to the screw of different model.
Description of drawings
Fig. 1 is the structural representation of the quick double-handle multifunctional screw driver of the utility model.
Fig. 2 is a two-way ratchet and pawl arrangement B-B cut-away view in this screwdriver.
Fig. 3 is a knurling handle A-A cut-away view in this screwdriver.
Fig. 4 is knurling handle in this screwdriver, ratchet, connecting rod connection diagram.
Among the figure: 1. cutter head, 2. knurling handle, 3. ratchet, 4. ratchet, 5. Square handle, 6. nut, 7. connecting rod.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
Shown in Figure 3 according to Fig. 1, cutter head 1 is installed in the square opening of knurling handle 2; Knurling handle 2 is connected with two-way click structure, pack in Square handle 5 front ends ratchet 4 and ratchet 3, ratchet 4 and ratchet 3 two-way engagements (as shown in Figure 2); Square handle 5 cross sections present rectangle, are provided with connecting rod 7 in the Square handle 5, and connecting rod 7 one ends are connected with knurling handle 2, and the other end is installed nut 6 (as shown in Figure 4).
The click structure is switchable in this screwdriver, promptly two-way click structure.Cutter head 1 is carried out clockwise with Square handle 5 or rotate counterclockwise by regulating knurling handle 2.Cutter head 1 did not change when hand went back to original position, the ratchet 4 that connects firmly does not with it change yet, and ratchet 3 rotates with Square handle 5, and work is carried out in 3 engagements of ratchet 4 ratchets more then, the normal pressure that is added in like this on the screw seldom even can not change with regard to changing, and is particularly conducive to the work of tightening to the screw of band spring.Square handle 5 is compared with round shaft, and it is big that the moment of torsion that is transmitted when cross-sectional area is identical is wanted, and this also is one of approach that realizes efficient purpose.The effect of knurling handle 2 is in addition, when screw is in more loose state, can directly rotates knurling handle 2 and tighten screw fast, and can apply normal pressure this moment by Square handle 5, and normal pressure can not change equally.
