Definitions
- the present invention relates to pliers for gripping Round bodies, such as spark plug connectors, the seams exhibit.
- Round bodies which are arranged in hole-like depressions, are often difficult to grasp and handle. This especially applies to spark plug connectors located in the engine block are attached to spark plugs screwed into recesses. When trying to use such a spark plug connector with a conventional one Taking pliers will often damage the plugs, especially if they have ceramic components. The so far for gripping such spark plug connectors or similar devices The tools used only serve their purpose imperfect.
- DE 41 04 622 C2 describes a device for assembling and disassembling disclosed by spark plug connectors that have bending tabs that are tubular is designed and on its receiving the spark plug connector Contains end grooves with protrusions that cover the edges of the flex tabs Reach in behind the spark plug connector by rotating the device. at This rotation is deep and inaccessible difficult to control and can damage the The plug and the spark plug.
- the object of the invention is a pair of pliers for gripping To create round bodies with seams that an easy and simple gripping allows without the round body damage and still hold the round body firmly in the forceps.
- the pliers according to the invention are suitable for gripping round bodies, which have a seam, such as from different spark plug connectors, which consist of two semicirculars Parts are put together by a seam are connected.
- spark plug connectors are, for. B. made of two metal parts, which are joined together by a seam are connected, these embodiments the Have the advantage that ceramic parts in the spark plug connector can be integrated. But these ceramic parts are very susceptible to breakage, so that when gripped with conventional ones Pliers can be easily damaged.
- the pliers according to the invention are suitable such spark plug connector without damaging the sensitive Ceramic body also from spark plug holes located deep in recesses deducted.
- the investment body in the form of a Half cylinder, which is adapted to the shape of the spark plug connector lies with its cylindrical surface on the outer surface of the spark plug connector.
- the locking pins are preferably cylindrical pins trained who are guided in a guide in which they by means of a lever from an upper release position in a lower gripping position can be moved.
- the distance A of Locking pins from the contact edges are preferably approximately 1 to 10 mm, in particular approximately 2 to 8 mm.
- the lever for operating the locking pin can be found in the upper Release position and locking devices in the lower gripping position who have these positions against you lock certain resistance.
- the locking devices can contain, for example, spring-loaded balls, which can be snapped into locking recesses.
- the pliers contain a contact body 12 in the form of a half cylinder, the inner cylindrical surface 14 of the outer shape of the round body to be caught, e.g. B. the spark plug connector, is adjusted.
- the body 12 to the gripping body is thus from the contact body 12 detected.
- the round body has seams, lay down the radial contact edges 16 of the half cylinder 12, which radially opposite each other in the course of the diameter of the half cylinder, to the seams.
- the lever 24 which on an extension part 32 of the contact body 12 is pivotally arranged, can be via a joint 34 locking pins 20 movably connected to the lever 24 from an upper release position to a lower gripping position pivot as shown in Fig. 1b and 2b.
- Recesses 20 in the contact body 12 can be made from the round body project outstanding construction parts, creating a additional hold of the round body in the pliers becomes.
