Abstract

The invention relates to mechanical engineering, namely to a hand tool for assembling and disassembling threaded connections with cables or closed pipelines. The purpose of the invention is to improve the performance properties. The sleeve 9 is displaced in the direction opposite to the jaws, with the halves 1 and 2 turning relative to each other. In this case, the longitudinal groove of the halves 1 and 2 is aligned with the longitudinal groove of the sleeve 9. A cable passes through the combined grooves, and then the sleeve 9 moves towards the jaws, while the halves 1 and 2 are compressed, and the jaws 4 clasp the wrapping element. Fixing the position of the halves 1 and 2 is carried out by turning the sleeve 9. Then the key begins to rotate. 1 hp ff. 6 Il.

The invention relates to mechanical engineering, namely to a hand tool for assembling and disassembling threaded connections with cables or closed pipelines.

The purpose of the invention is to improve the operational properties due to the dense coverage of the element to be wrapped with sponges.

FIG. 1 shows a special allen key with a closed throat, general view; figure 2 - the same, with open mouth, a general view; on fig.Z - section aa in figure 1; figure 4 - section bB in fig.Z; figure 5 is a view In fig.Z; figure 6 - section GG on fig.Z.

The special allen key contains a hollow cylindrical body, made of two halves 1 and 2, forming a longitudinal groove 3 in cross section (FIG. 4). On each half 1 and 2, sponges 4 (figure 5) are made from one end. Both halves 1 and 2 are connected by a strap 5, fixed at half 1 rigidly, and at half 2 - hinged. This provides the possibility of turning them one relative to another. In half 1 and 2 are made grooves 6 and 7, in which is placed the spring 8.

On halves 1 and 2, a sleeve 9 with a longitudinal groove 10 is installed coaxially. On one of the halves 1 or 2, a pin 11 is fixed at one end. On the sleeve 9, there is also a T-shaped groove 12, in which the free end of the pin 11 is located.

Special allen key works as follows.

The sleeve 9 is displaced in the direction opposite to the jaws 4, with the halves 1 and 2 turning one relative to the other.

goy (figure 2). The longitudinal groove 3 of the halves 1 and 2 coincides with the longitudinal groove 10 of the sleeve 9. A cable or pipeline (not shown) passes through the combined longitudinal grooves 3 and 10, and then the sleeve 9 moves towards the jaws 4. In this case, the half 1 and 2 are compressed and the jaws 4 compress the element to be wrapped (not shown). Fixing the position of the halves 1 and 2 is carried out by turning the sleeve 9. In this case, the rotary groove 3 of the halves 1 and 2 is covered by the sleeve 9.

Then the special socket wrench begins to rotate.

Claims (2)

1. A special allen key containing a hollow cylindrical body with a longitudinal groove and jaws forming an open mouth, and a bar characterized in that, in order to improve the performance properties due to the tight coverage of the element to be wrapped with jaws, the key is provided with a coaxially mounted on the body with the possibility of rotation and axial movement of the sleeve with a longitudinal groove, and the body is made of two opposite spring-loaded with the possibility of rotation of one relative to the other half, and the bar at one end fixed to one of the half and hinged - on the other. 2. A key according to claim 1, characterized in that it is provided with a pin fixed to one of the halves at one end, and in the sleeve there is a T-shaped groove for accommodating the free end of the pin. g Gpf WCi99l eleven FIG. 6
