Abstract
The utility model relates to a screwdriver auxiliary device. As is known to all, when a person uses a screwdriver for many times, the screwdriver is easy to shake left and right and can not be fixed easily, and the difficulty of the rotation of the screwdriver is added. Therefore, the screwdriver auxiliary device comprises an outer shell which is of a square hollow three-dimensional structure. Symmetrical grooves are formed on the inner sides of two parallel edges of the outer shell, a retractable spring used for clamping a screwdriver rod is arranged between the grooves in a clamping mode, an upper cover plate which is in a triangular three-dimensional cavity shape is arranged above the retractable spring, a lower cover plate which is in a triangular three-dimensional cavity shape is arranged below the retractable spring, the upper cover plate and the lower cover plate are symmetrical, and a triangular screwdriver rod hole is formed between the triangular three-dimensional cavity and the retractable spring. The cross section of the retractable spring is in a reversed T shape, the reverse-T-shaped retractable spring is connected on the outer shell through a spring. The upper cover plate is a detachable cover plate. The screwdriver auxiliary device is simple in structure, scientific in design and convenient to use, the screwdriver rod can not shake left and right when a screw is screwed, the stability is increased when the screw is screwed, and speed and comfort of screwing of the screw are improved.
Description
Technical field
The utility model relates to a kind of building implement commonly used, particularly a kind of screwdriver servicing unit.
Background technology
As everyone knows, people need therefore to cause the unstability of screw easily with bigger strength when rotary screw cutter many times, and causing screwdriver to damage object or screw deflection or screw can not screw in.Especially harder in quality, and the place that will screw in is when being in unfavorable position such as eminence, screwdriver rocks from side to side easily, is difficult to fixingly, has increased the rotation difficulty, and operation is difficulty.Therefore, develop a kind of screwdriver servicing unit and become particularly important.
Summary of the invention
The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome prior art, and the control screwdriver rocked from side to side, improves the screwdriver servicing unit of speed and the comfort level of rotary screw when a kind of rotary screw was provided.
For solving the problems of the technologies described above, this screwdriver servicing unit, comprise shell, shell is the stereochemical structure of square hollow, the inboard of two parallel edges of shell has symmetrically arranged groove, be arranged with the telescopic flexible semi-annular jade pendant that clamps for the screwdriver knife bar between the groove, flexible semi-annular jade pendant upper and lower is arranged with the upper and lower cover plate of three-dimensional cavity-like triangular in shape, forms triangle screwdriver knife bar hole between the three-dimensional cavity of this triangle and the flexible semi-annular jade pendant.
During use, the screwdriver knife bar is put into triangle screwdriver knife bar hole, then by the flexible flexible semi-annular jade pendant screwdriver knife bar that is fixedly clamped.
So design, the screwdriver knife bar can not rock from side to side when rotary screw, the stability when having increased rotary screw, the speed when having improved rotary screw and comfort level.
As optimization, the cross section of flexible semi-annular jade pendant is inverted T-shaped, and the head of the flexible semi-annular jade pendant of this inverted T-shaped is connected on the shell by spring.Processing is convenient in so design.
As optimization, the afterbody center of the flexible semi-annular jade pendant of inverted T-shaped is provided with for the concave arc groove that fixes the screwdriver knife bar.So set screw cutter knife bar is convenient in design.
As optimization, upper cover plate is detachable cover plate, and detachable cover plate comprises for the square upper cover plate I that covers spring and for two triangle upper cover plate II that fix the screwdriver knife bar.So design is convenient to fix the screwdriver knife bar.
As optimization, the aperture in screwdriver knife bar hole and screwdriver knife bar size are complementary.So design is easy to use.
The utility model screwdriver servicing unit, simple in structure, design science, easy to use, the screwdriver knife bar can not rock from side to side when rotary screw, the stability when increasing rotary screw, the speed when having improved rotary screw and comfort level.
Description of drawings
Below in conjunction with accompanying drawing this screwdriver servicing unit is described further:
Fig. 1 is the perspective view of this screwdriver servicing unit;
Fig. 2 is the perspective view of the upper cover plate disassembly status of this screwdriver servicing unit.
Among the figure: 1 is that shell, 2 is that groove, 3 is that flexible semi-annular jade pendant, 4 is that concave arc groove, 5 is that screwdriver knife bar hole, 6 is that upper cover plate I, 7 is that spring, 8 is the upper cover plate II.
The specific embodiment
As shown in Figure 1, 2, this screwdriver servicing unit, comprise shell 1, shell 1 is the stereochemical structure of square hollow, the inboard of 1 two parallel edges of shell has symmetrically arranged groove 2, be arranged with the telescopic flexible semi-annular jade pendant 3 that clamps for the screwdriver knife bar between the groove 2, flexible semi-annular jade pendant 3 upper and lowers are arranged with the upper and lower cover plate of three-dimensional cavity-like triangular in shape, form triangle screwdriver knife bar hole 5 between the three-dimensional cavity of this triangle and the flexible semi-annular jade pendant 3.
The cross section of flexible semi-annular jade pendant 3 is inverted T-shaped, and the head of the flexible semi-annular jade pendant 3 of this inverted T-shaped is connected on the shell 1 by spring 7; The afterbody center of the flexible semi-annular jade pendant 3 of inverted T-shaped is provided with for the concave arc groove 4 that fixes the screwdriver knife bar; Upper cover plate is detachable cover plate, and detachable cover plate comprises for the square upper cover plate I 6 that covers spring 7 and for two triangle upper cover plate II 8 that fix the screwdriver knife bar; The aperture in screwdriver knife bar hole 5 and screwdriver knife bar size are complementary.
During use, at first adjust flexible semi-annular jade pendant 3, allow the screwdriver knife bar pass screwdriver knife bar hole 5; Then, pin shell 1 with a hand, another hand tighten screw cutter.Wherein, spring 7 connects together with flexible semi-annular jade pendant 3, and it is flexible to be used for supporting flexible semi-annular jade pendant; Upper cover plate is detachable, is convenient to install flexible semi-annular jade pendant 3; Consider that the screwdriver knife bar is cylindrical, ad hoc flexible surely semi-annular jade pendant 3 contact screwdriver knife bar positions are concave arc groove 4.In addition, when the turn of the screw, insert screwdriver, this moment, flexible semi-annular jade pendant 3 can clamp the screwdriver knife bar according to the thickness of the screwdriver knife bar aperture by spring 7 automatic set screw cutter knife bar holes 5, kept it to stablize, and had just solved the difficult problem that screwdriver rocks from side to side during rotation.In addition, can regulate the upper-lower position of this screwdriver servicing unit during rotary screw, in the hope of obtaining best rotation comfort level.
The above-mentioned specific embodiment only is concrete case of the present utility model; scope of patent protection of the present utility model includes but not limited to product form and the style of the above-mentioned specific embodiment; any screwdriver servicing unit that meets the utility model claims and any person of an ordinary skill in the technical field all should fall into scope of patent protection of the present utility model to its suitable variation or modification of doing.
