Description

The invention relates to a hand tool, and in particular to a device for a double-sided angled screwdriver combined with interchangeable rods, used for screwing and unscrewing screws with various recesses in the heads in places with limited access, as well as for adjusting modules and blocks of electronic equipment (REA).

A screwdriver is known from the prior art (Patent RU No. 81148 MKPO: 08-04) comprising a handle consisting of front and rear parts and a rod mating with the front part, in the end surface of which a rectangular hole is made to accommodate the bits. The back of the handle is made tapering to the end, which is made in the form of a hat on the leg. The disadvantage of a screwdriver is the inability to use it in places with limited access, as well as the presence of a magnet in the hole of a rectangular shape of the rod, which involves the use of bits exclusively from magnetic material to ensure their fixation in the rod.

Known combination screwdriver (Patent for invention RU No. 1279814 IPC: BV 15/00, published 12/30/1986), containing a handle with a cavity, a rod installed in it with working tips on the ends and elements fixing the rod. At the bottom of the cavity, cuts intersecting one another are made, interacting with working tips. The disadvantage of this screwdriver is the inability to use it in places with limited access.

Known double-sided curved screwdrivers for screws and screws with straight and cross-shaped slots (GOST 17199-88 SCREWDRIVERS FITTING AND MOUNTING Technical conditions, type 2 execution 3 and 4, page 7), each of which is a rod with two L-shaped curved sections placed in one plane, ending with working parts directed in opposite directions. In one of these screwdrivers, the working parts are made in the form of rectangular blades, and in the other, the working parts are cross-shaped.

As a prototype for the claimed technical solution, an angled screwdriver for screws with a simple slot was chosen (EQUINET catalog (STAHLWILLE company subdirectory), p. 207, No. 10546, internet: www.equinet.ru), containing a handle with two opposite ends fixed to it L-shaped rods, each of which has an elongated part, turning into a curved section, ending with a working part. Moreover, the rods are placed in one plane, and their working parts in the form of rectangular blades made in planes perpendicular to each other, are directed in opposite directions.

The technical problem solved by the creation of this invention is the low-tech installation and dismantling work due to the placement of the rods in one plane and the orientation of their working parts in opposite directions. In addition, the rods are made of the same material, have the same length, and are not interchangeable, which excludes the possibility of combined use of the rods and creates a significant range of screwdrivers.

The technical result of the claimed technical solution is aimed at creating a double-sided angled screwdriver combined with advanced technological capabilities for its use in places with limited access due to the use of L-shaped interchangeable rods of different material in it with the possibility of their placement in different planes.

The technical result is achieved by the fact that a double-sided angled screwdriver contains a handle with two L-shaped rods fixed at its opposite ends, each of which has an elongated part, passing from one side to a curved section ending with a working part. Moreover, it differs from the prototype in that in the end surfaces of the opposite ends of the handle, nests are made that are different from round in shape, in which rods are proportionate to them and similar in shape, made on the other side of their elongated part. The rods are fixed in the sockets with fasteners in the form of nuts placed on the threaded surfaces of the peripheral sections of the handle. At the same time, each fastening element is made with at least one fixing element interacting with the rim separating the pin and the elongated part of the shaft.

The invention is illustrated by drawings, where:

FIG. 1 is a general view of a double-sided angled combined screwdriver;

FIG. 2 - general view of the handle;

FIG. 3 is a general view of an L-shaped rod with a working part in the form of a rectangular blade made parallel to the axis of the elongated part;

FIG. 4 is a general view of an L-shaped rod with a working part in the form of a rectangular blade made perpendicular to the axis of the elongated part;

FIG. 5 is a general view of an L-shaped rod with a working part in the form of a holder for socket heads;

FIG. 6 is a general view of the fastener.

Combined double-sided angled screwdriver contains a handle 1 (Fig. 1, 2) with two rods 2, 3 fixed on its opposite ends (Fig. 1, 3, 4, 5) L-shaped, which are interchangeable, as well as fasteners 4 ( Fig. 1, 6) for fixing the rods 2, 3 on the handle 1.

The central part of the handle 1 can be closed by an insulator 5 placed on it (Fig. 1, 2), made, for example, in the form of a sleeve of elastomeric material. The peripheral sections 6 (Fig. 2) of the handle 1 are made with a threaded surface. In the end surfaces 7 of the opposite ends of the handle 1, sockets 8 (Fig. 2) are made, having a shape different from round, for example, hex.

Each of the rods 2, 3 (Figs. 1, 3, 4, 5) has an elongated part 9, passing from one side to a curved section ending with a working part 10, as well as a trunnion 11 with a truncated cone-shaped shank 12, made on the other side of the elongated part 9 (Fig. 3, 4, 5). While the pin 11 and the elongated part 9 of the rod are separated by a rim 13 (Fig. 3, 4, 5) of a cylindrical shape. The elongated part 9 can be made with different lengths depending on the technological need.

The rods 2, 3 can be made of various materials, both magnetic and anti-magnetic, for example, to work in places with limited access when servicing microwave transmitters.

The pins 11 of the rods 2, 3 are made, for example, in the form of hexagons commensurate with the sockets 8 (Fig. 2) of the handle 1 having a similar shape, which provides angular fixation of the rods 2, 3 in the sockets 8 with the possibility of their mounting with different mutual angular position, that is, in various planes. Moreover, the presence of trunnions And shanks 12 in the form of a truncated cone ensures the manufacturability of mounting rods 2, 3.

The working part 10 is made, for example, with a rectangular blade, which can be placed both parallel to the axis of the elongated part 9 of the rod (Fig. 3), and perpendicular (Fig. 4). The rectangular blade of the working part 10 may also have different thicknesses and widths with the formation of a step adjacent to the curved portion of the rod, and depending on the technological need, a different length.

The working part 10 of the rods 2, 3 can also be performed:

- rectangular shape, for example, according to GOST 24437;

- cross-shaped, for example, according to GOST10754;

- in the form of a square and a hexagon for screws with internal squares and hexagons;

- in the form of Phillips cross slot;

- in the form of a shank for internal TORX and TRI-WING screws;

- in the form of a holder for socket heads (Fig. 5).

So, a combination angled double-sided screwdriver can be assembled with the working parts of 10 rods 2, 3 of various configurations.

The fasteners 4 (Fig. 6) are made in the form of nuts placed on the threaded surfaces of the peripheral sections 6 (Fig. 2) of the handle 1. Each fastener 4 has at least one fixing element 14 (Fig. 6), made, for example , in the form of a protrusion in the form of a segment adjacent to the end surface 15 (Fig. 6) of the fastener 4. The fixing element 14 interacts with the rim 13 (Fig. 3, 4, 5) of the rods 2, 3, while ensuring their axial fixation in nests 8. The outer surface 16 (Fig. 6) of the fastener 4 can be made, for example, tsili knurled-cylindrical or in the form of a polyhedron for easy screwing.

Assembly screwdriver angular bilateral combined as follows.

If necessary, an electric insulator 5 (Fig. 1, 2) is placed on the central part of the handle 1, made in the form of a sleeve made of elastomeric material, for example, of heat-shrinkable rubber, which takes the form of a central part.

In the slots 8 (Fig. 2), made in the end surfaces 7 of the opposite ends of the handle 1, the pins 11 of the rods 2, 3 (Fig. 3, 4, 5) are placed, which are placed in the planes necessary for work and fixed with fasteners 4 (Fig. . sixteen). The fixation is ensured by the interaction of the fixing elements 14 (Fig. 6) of the fastening elements 4 with the rims 13 (Fig. 3, 4, 5) of the rods 2, 3. If necessary, the rods 2, 3 are chosen with different lengths and are installed in various combinations .

The angled two-sided combined screwdriver assembled in this way is used to screw and unscrew screws with various recesses in the heads of fasteners in places with limited access, as well as to adjust the modules and blocks of REA.

An example of the use of the claimed device can be a double-sided angled screwdriver combined with interchangeable rods for screwing and unscrewing screws with various recesses in the heads in places with limited access, and also used to adjust the modules and REA units.

The rods 2, 3 of this screwdriver are L-shaped and are made of steel 50HFA or U7, and with the antimagnetic design of steel 12X18H9T.

For assembling and disassembling the units of REA units with fixing screws located in the underreporting of the bearing surfaces with limited access, rods 2, 3 with the necessary working parts 10 are selected depending on the shape of the understatement in the screw heads. The rods 2, 3 are selected the desired length from the required material and are installed in the necessary planes in the slots 8 (Fig. 2) of the handle 1 and are fixed with fasteners 4 (Fig. 6).

For fasteners with a simple slot, L-shaped rods 2, 3 with working parts 10 in the form of rectangular blades are used, while one rod, for example, rod 2, has a rectangular blade parallel to the axis of its elongated part 9 (Fig. 3), and in another, for example, the rod 3 is perpendicular (Fig. 4). This configuration allows you to alternately work rods 2, 3, turning the mounting screw at a certain angle.

Thus, the proposed technical solution made it possible to create a double-sided angled screwdriver combined with advanced technological capabilities for its use in places with limited access.
