Description

The invention relates to a disassembly tool, in particular a widely applicable, connectable to a socket wrench insert, for dismantling a screw or a bolt with angled head.

The conventional socket wrench has an operating end and a connecting end, the operating end being plugged onto a screw or bolt and the connecting end serving to connect a socket wrench. In the conventional sockets, there are two types of connection end; in one type, the connecting end on the outer circumference is hexagonal and round-shaped on the inner circumference, while in the other type, the connecting end on the outer circumference is round and formed on the inner circumference square. In the conventional socket wrenches, there are also two types of fittings, wherein in one type, the connector is provided with a recess having a hexagonal section, while in the other type, the connector is formed as a square, with the aforementioned second type of conventional socket wrench fits. If the user wishes to use a conventional socket wrench insert of the first type, but has only a socket wrench with a square fitting, disassembly work can not be performed; if the user wants to use a conventional socket with a hexagonal recess, but has only a socket wrench of the second kind available, the disassembly work can not be performed because the socket and the socket wrench do not match.

In the following, objects, features and advantages of the present invention will become more apparent from the detailed description of embodiments and the accompanying drawings. The invention should not be limited to the features shown in the description and in the drawing.

According to the first preferred embodiment of 1 to 3 includes the socket wrench according to the invention 1A an end of operation 10A and a connection end 20 , each at both ends of the socket 1A are located, the operating end 10A a recording 12A includes, which at the operating end 10A is arranged open to the outside, the recording 12A a variety of teeth 122A , preferably twelve teeth, comprising, wherein the twelve teeth 122A at an equal distance from each other in the receptacle 12A are arranged annularly, with the twelve teeth 122A allow workpieces having a header with different angled profiles to be inserted easily and into the receptacle 12A so that one of the angles of a polygonal workpiece between two adjacent teeth 122A engages and is thereby limited, the recording 12A can also be used to accommodate different socket wrench inserts; the connection end 20 includes a polygonal cave 22 , a polygonal body 24 , a first ball notch 26 , a second ball notch 28 and an anti-slip part 29 , where the polygonal cave 22 on the inner ring surface of the connection end 20 is located, with the perimeter of the polygonal cave 22 has a four-edged section, the polygonal cave 22 and the recording 12 interconnected with the polygonal cave 22 four recesses 222 may include, respectively, at the locations of the included angles of the polygonal cavity 22 are arranged and relative to the connection end 20 run vertically, with the polygonal body 24 on the outer ring surface of the connection end 20 is located, the scope of the polygonal body 24 has a hexagonal section, wherein the first ball notch 26 on the sides of the polygonal cave 22 ' arranged and provided that a ball of a square connector of the conventional socket wrench in the first ball notch 26 can engage, with the second ball notch 28 at the periphery of the polygonal body 24 annularly arranged and provided that a C-shaped elastic element of the fitting of the hexagonal recess of the conventional socket wrench insert in the second Kug notch 28 can engage. Due to the fact that the socket wrench insert according to the invention 1A at the same time a polygonal cave 22 and a polygonal body 24 has, it is suitable for socket wrenches of various types, which is very convenient for the user. Furthermore, the anti-slip part 29 at the periphery of the polygonal body 24 arranged and overlaps the second ball notch 28 Not.

4 and 5 each show a socket 15 and a socket 10 according to the second and third preferred embodiments, wherein the two socket wrench inserts 1C in terms of construction, the in 1 shown socket wrench insert 1A with the difference that corresponds to the operating ends 10B . 10C can be formed in different dimensions and shapes, so that for different workpieces of the socket wrench 1B ( 1C ) with the appropriate operating end 10B ( 10C ) can be used.

For the use of the socket wrench 1A of the first preferred embodiment 6 and 7 directed. As in 6 shown, a socket wrench A is used, which has a square, on which a ball is arranged; the socket wrench insert 1A becomes with the polygonal cave 22 attached to the square of the socket wrench A, wherein the ball for snapping into the first ball notch 26 of the socket wrench insert 1A is brought, causing the socket wrench 1A and the socket A are securely joined together, so that the socket wrench 1A can be made by turning the socket wrench A to rotate to tighten or loosen a workpiece.

As in 7 shown, a socket wrench B is used, which has a hexagonal recess, a telescopically adjustable recess and a C-shaped elastic member, wherein the telescopically adjustable recess on the outer circumference of the recessed end of the socket wrench B is arranged annularly, wherein the telescopically adjustable recess is connected to the included angles of the hex recess, wherein the C-shaped elastic member is disposed in the telescopically adjustable recess and partially protruding from the hex recess; the polygonal body 22 of the socket wrench insert 1A is inserted into the recess of the socket wrench B so that the C-shaped elastic element in the second ball notch 28 of the socket wrench 1A locks; thus, the socket will be used 1A and the socket wrench B securely joined together.

For the connection of the socket wrench according to the first preferred embodiment with the socket wrench according to the third preferred embodiment is on 8th and 9 directed. To insert the socket wrench B into which the socket wrench insert 1A is plugged in, the operating end 10C of the socket wrench insert 1C with the connection end of the socket wrench insert 1A be joined together, wherein the polygonal body 24 of the socket wrench insert 1A in the recording 12C of the socket wrench insert 1C stuck and through the teeth 122C is held, so the socket wrench 1A safe with the socket wrench 1C is assembled and not relative to the socket 1C can turn. In this way, the length of the socket wrench can be increased. That is: when the diameter of the cut of the picture 12C of the socket wrench insert 1C greater than the diameter of the operating end 10C is, the teeth can 122C the polygonal body 24 the end of the operation 10C another same socket wrench 1C hold tight; so the entire operating length of the socket wrench inserts as needed by assembling the same constructed sockets 1C be increased in order.

Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that the invention is not limited to these embodiments, but rather modifications are possible in the manner that individual features omitted or other combinations of features can be realized as long as the scope of protection of the appended claims is not abandoned.
