SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an elasticity chuck to all be the robust chuck of clamping when solving the coating is done to the general pipe seal wire that proposes in the above-mentioned background art, need twist the leather sheath that moves the nut and make the inside when luer chuck clamping and die, make to press and press the dress loaded down with trivial details slow, and the nut dies because pressure is uncertain, probably has the problem that the damage was waited to press from both sides the thing.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an elasticity chuck, includes the lantern ring, there are two connecting rods about ring hole symmetry rigid coupling on the top surface of the lantern ring, the other end rigid coupling of two connecting rods has chuck main body, chuck main body's other end rigid coupling has the interpolation piece, and the symmetry has seted up the channel in chuck main body, the rigid coupling has the pivot between the both sides wall of channel, it is connected with the chuck shell fragment to rotate in the pivot, the other end of chuck shell fragment extends to between two connecting rods, and the chuck shell fragment extends and to have the clamping piece on the lateral wall of end, the opposite side rigid coupling of clamping piece has the cushion, and chuck main body external slip has cup jointed the chuck sleeve, and the rigid coupling has the interpolation board on the lateral wall of the lantern ring, the other end rigid coupling that adds the board has the guide bar, the slide has been seted up on the guide bar, sliding connection has.

Preferably, the adding plate is perpendicular to the guide rod, and the guide rod is provided with a ruler strip.

Preferably, the number of the guide rods is two, and the guide rods are parallel to the dividing surface of the clamping piece.

Preferably, the adding block is provided with an external thread.

Preferably, the connecting rod is parallel to the guide rod.

Preferably, the clamping piece is of a semi-annular structure, and the annular hole is positioned right above the annular hole of the lantern ring when the clamping piece is closed.

Compared with the prior art, the beneficial effects of the utility model are that: this elasticity chuck moves down through the chuck sleeve outside the chuck main part and extrudes the chuck shell fragment, makes the chuck shell fragment drive the clamping piece and the soft rubber pad closure of surveying in it to press from both sides tightly and stretch into the intra-annular thing of treating to press from both sides of cover, when shifting up the chuck sleeve, the chuck shell fragment drives clamping piece and soft rubber pad bullet and opens, takes out the folder, thereby reaches the swift convenient purpose of pressing from both sides dress, and through the buffering deformation of soft rubber pad, reaches the increase and presss from both sides solid power, and is difficult for damaging the purpose of folder.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: an elastic chuck comprises a lantern ring 1, two connecting rods 2 are symmetrically and fixedly connected on the top surface of the lantern ring 1 around a ring hole, a chuck main body 3 is fixedly connected at the other ends of the two connecting rods 2, an adding block 4 is fixedly connected at the other end of the chuck main body 3, and the chuck main body 3 is symmetrically provided with a channel, a rotating shaft 5 is fixedly connected between two side walls of the channel, a chuck elastic sheet 6 is rotatably connected on the rotating shaft 5, the other end of the chuck elastic sheet 6 extends to the position between the two connecting rods 2, and the side wall of the extending end of the chuck elastic sheet 6 is fixedly connected with a clamping sheet 7, the other side of the clamping sheet 7 is fixedly connected with a soft rubber pad 8, a chuck sleeve 9 is sleeved outside the chuck main body 3 in a sliding manner, an adding plate 10 is fixedly connected to the side wall of the lantern ring 1, a guide rod 11 is fixedly connected to the other end of the adding plate 10, a slide way is formed in the guide rod 11, a slide block 12 is connected in the slide way in a sliding manner, and the other end of the slide block 12 is fixedly connected with the chuck sleeve 9;
