one end of the steel wire is connected in the gun tube, and the other end of the steel wire is connected in the tube head.

Preferably, the steel wire is wound from a plurality of thin steel wires.

Preferably, two ports of the spherical pipe body are provided with arc chamfers.

Preferably, the barrel mouth has an arc-shaped chamfer.

Preferably, the spherical pipe body and the supporting pipe are both iron pipe bodies.

The utility model has the advantages that: can be crooked with the steel wire part to can stretch into narrow and small space with it in, make the butt joint of the rivet in tube head and the narrow and small space, thereby pulling the rivet, realize the riveting operation in the narrow and small space.

Drawings

Fig. 1 is a cross-sectional view of a universal pull rod device of a riveter according to the present embodiment.

Detailed Description

The universal pull rod device of the hand riveter of the present invention is further described with reference to fig. 1.

The utility model provides a universal pull rod device of hand riveter, characterized by: comprises a gun barrel 1, a steel wire 2, a supporting component and a tube head 5.

The supporting component comprises a plurality of spherical pipe bodies 3 and supporting pipes 4, the spherical pipe bodies 3 and the supporting pipes 4 are sleeved on the steel wire 2 at intervals, flaring ports 41 at two ends of the supporting pipes 4 are arranged, and the inner walls of the flaring ports 41 are of arc-shaped structures and are matched with the spherical surfaces of the spherical pipe bodies 3. That is, in the process of bending the steel wire 2, the inner wall of the flared opening 41 is attached to the outer wall of the spherical pipe body 3 and can slide relative to the outer wall of the spherical pipe body, so that the steel wire 2 can be supported in the process of bending.

One end of the steel wire 2 is connected in the gun barrel 1, and the other end is connected in the tube head 5.

The utility model discloses when using, hydro-cylinder and piston structure have in barrel 1, have triangle jack catch mechanism in the tube head 5, and the one end and the piston connection of steel wire 2 correspondence barrel 1, the one end and the triangle jack catch that steel wire 2 corresponds tube head 5 are connected, remove through piston pulling steel wire 2 to pulling triangle jack catch removes in tube head 5, realizes the clamp of triangle jack catch jaw mouth tightly and unclamps. When riveting the position in the narrow space, the steel wire 2 is bent to enable the pipe head 5 to enter the narrow space and correspond to the rivet; and starting the hand riveter, pulling the steel wire 2 and the triangular clamping jaws in the pipe head 5 by the piston to move, and clamping the rivet by the triangular clamping jaws to realize riveting operation. Above-mentioned in-process, cup joint at the outside spherical body 3 of steel wire 2 and stay tube 4 at the in-process of blind rivet, can play the fixed effect of support to steel wire 2 for steel wire 2 can stimulate the removal of triangle jack catch. To sum up, the utility model discloses can rivet the operation to the position in the narrow and small space, show to have promoted and have the utility model discloses a draw the commonality of riveter.

In this embodiment, the structure of the oil cylinder and the piston in the gun barrel and the structure of the triangular claw in the barrel head are the prior art, and therefore, detailed description is not provided in this embodiment.

The embodiment is further configured as follows: the steel wire 2 is formed by winding a plurality of thin steel wires. Steel wire 2 can be crooked, and the tube head 5 of being convenient for extends to narrow and small space in, possesses stronger structural strength again simultaneously, under the supporting role of spherical body 3 and stay tube 4, pulling triangle jack catch that can be stable removes, reaches the effect of rivet.

The embodiment is further configured as follows: two ports of the spherical pipe body 3 are provided with arc chamfers 31. This arc chamfer can play the effect of dodging, can be convenient for the bending of steel wire 2, can also play the protection effect to steel wire 2 when bending process simultaneously, avoids the problem of the 2 pressure losses of steel wire that the right angle border will be crooked.

The embodiment is further configured as follows: the barrel 1 has a nozzle with an arcuate chamfer 11. In a similar way, the arc-shaped chamfer 11 can not only play a role of bending and avoiding the steel wire 2, but also prevent the problem of pressure loss of the steel wire 2, thereby remarkably improving the stability of the bending deformation of the metal steel wire 2.

The embodiment is further configured as follows: the spherical pipe body 3 and the supporting pipe 4 are both iron pipe bodies. Iron body structural strength is higher, can play stable supporting effect to steel wire 2, and the steel wire 2 of being convenient for carries out stable riveting operation with the stable pulling of triangle jack catch to the operating personnel of being convenient for.
