Description

Screwdriver for preventing breakaway

The present invention relates to an escape prevention driver. And more particularly, to an escape prevention driver for preventing a tip of a driver from deviating from a screw groove when the screw is tightened or loosened.

Generally, a screwdriver is a tool used to screw and unscrew a screwdriver and a ten-screwdriver, depending on the application. These screws are screwed or loosened by inserting the tip of the screwdriver into the screw groove and rotating it.

Such a conventional screwdriver should use a screw having a size corresponding to the size of the screw, that is, the size of the groove formed in the screw head. If screws and screws having different sizes are used, It becomes difficult to solve.

In particular, if the size of the screwdriver tip is smaller than the threaded groove, it is possible to rotate the screw to some extent. However, since the screwdriver can not transmit the rotational force properly, The groove is damaged.

To prevent this problem from happening, drivers of various sizes must be taken and carried. It is very troublesome for the operator to carry several tools.

Korean Patent No. 10-1445676 (2014.09.23.)

In order to solve the above-mentioned problem, the present invention can tighten or loosen screws of various sizes with a single screwdriver, and in order to prevent the driver tip from being detached from the screw groove, And it is an object of the present invention to provide an escape prevention driver.

In order to achieve the above-mentioned object, the present invention provides a guiding apparatus comprising: a guiding tube having a guide hole penetrating therein in a longitudinal direction, hinged to at least two driver tips to be pivoted; And a reciprocating rod which is inserted in the guide hole and is moved in the forward and backward direction and whose front end is in contact with the driver tip, wherein the driver tip is opened by advancing movement of the reciprocating rod, And the distance between the first and second projections is reduced.

The escape prevention driver includes a handle provided with a fastening groove formed at the front and into which the guide tube is inserted and a through hole communicating with the guide hole of the guide pipe inserted in the fastening groove in the longitudinal direction, .

Further, an elastic member is disposed between the head portion and the handle, and one end of the elastic member is in contact with the handle, and the rear end of the elastic member is in contact with the head portion and elastically supports the reciprocating rod backward .

At this time, a pinion gear portion is formed at a rear end of the driver tip, a rack gear portion is formed at a front end of the reciprocating rod, and the pinion gear is rotated by engaging with the rack gear portion so that the front end of the driver tip is opened or collected .

The present invention is advantageous in that work efficiency can be improved by fastening or loosening screws of various sizes with a single screw driver, and by improving the convenience of screw fastening and separating operations. In addition, there is no need to provide drivers of various sizes, which is economical, and there is an effect of eliminating the troubles of storing and managing a plurality of drivers.

FIG. 6 is a cross- In a disassembled state of a departure-avoidance driver according to a preferred embodiment of the present invention.

Hereinafter, a departure prevention driver 100 according to a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG.

According to a preferred embodiment of the present invention, the departure prevention driver 100 includes a handle 110, a guide tube 120, a reciprocating rod 140, and an elastic member.

Specifically, the handle 110 has a through hole 112 formed in the longitudinal direction thereof and a coupling groove 114 formed in the front to communicate with the through hole 112.

The rear portion of the guide pipe 120 is inserted and coupled to the coupling groove 114 formed at the front. At this time, the through hole 112 is arranged to communicate with the guide hole 122 of the guide tube 120 inserted in the coupling groove 114 in a straight line.

The guide hole 122 is formed in the guide tube 120 in a longitudinal direction and is hinged to the guide tube 120 so that at least two driver tips 128 are rotated.

The reciprocal rod 140 is inserted into the communicating through hole 112 and the guide hole 122 to be moved in the forward and backward direction and the front end portion of the reciprocating rod 140 is in contact with the driver tip 128, Causing the tip 128 to pivot.

Specifically, a plurality of openings 124 are formed in the front end of the guide tube 120 so as to be recessed toward the rear, in which the driver tips 128 are disposed, according to the number of the driver tips 128, A pinhole 125 into which a pin 126 for hinging the driver tip 128 to the guide tube 120 is inserted is formed.

The driver tip 128 disposed in the opening 124 passes through the pin 126 and thus the driver tip 128 is hinged to the guide tube 120.

A pinion gear portion 129 is formed at the rear end of the driver tip 128 and a rack gear portion 146 is formed at the front end of the reciprocating rod 140. When the pinion gear portion 129 is engaged with the rack gear portion 146, So that the front end of the driver tip 128 is opened or collected.

In other words, the driver tip 128 is configured to be opened by the advance operation of the rack gear portion 146 formed in the reciprocating rod 140, and conversely, when the reciprocating rod 140 is retracted, the driver tip 128 is gathered .

A head portion 142 is provided at the rear end of the reciprocating rod 140. One end of the head portion 142 is in contact with the handle 110 and the other end of the head portion 142 is in contact with the head portion 142, An elastic member 150 for elastically supporting the elastic member 140 rearward is disposed.

The elastic member 150 may be formed as a spring and an elastic member 150 may be provided at the rear end of the handle 110 and at the front end of the head 142 to fix the elastic member 150, Receiving grooves 116 and head grooves 144 may be respectively formed.

As shown in FIGS. 1 and 4, since the reciprocating rod 140 is moved backward by the elastic member 150 when the unblocking driver 100 according to the preferred embodiment of the present invention is not used, ) Is maintained in the closed state.

However, when the departure-avoiding driver 100 is used, the head portion 142 is pushed forward to bring the driver tip 128 into close contact with the threaded groove. At this time, by the reciprocating rod 140 moving forward, The driver tip 128 is extended to the outside and the driver tip 128 is positioned outside the screw groove.

With this operation, the driver tip 128 can stably contact the screw groove regardless of the size of the screw, so that the rotational force can be transmitted.

As described above, the escape prevention driver 100 according to the preferred embodiment of the present invention can tighten or loosen screws of various sizes and can perform various screw tightening or separating operations without having drivers of various sizes Very useful.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be. Therefore, the embodiments disclosed in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and accompanying drawings.
