The invention content is as follows:

the utility model discloses an invention purpose discloses the mounting tool of two formula collapsible packing rings that unilateral bolt used.

Realize the utility model discloses a technical solution as follows: the key point is that one end of the main body is provided with a clamping part which can be bent and deformed to keep the state of the two-piece type folding washer, and one end of the clamping part is provided with a connecting end which is connected with a screw rod of a unilateral bolt.

The clamping part is provided with a plate-shaped end which is integrated with the main body, and the other vertical plate which is vertically connected with the plate-shaped end is of a T-shaped structure.

The vertical plate and the plate-shaped end are fixedly and integrally connected.

The vertical plate is movably connected with the plate-shaped end.

The end face of the connecting end is provided with a blind hole, or the end face of the connecting end is provided with a connecting convex part.

The blind holes or the connecting convex parts are square or hexagonal or other polygons.

One surface of the connecting convex part is provided with an elastic part which is of a collision bead structure or an elastic lug protruding from the surface.

The utility model has the advantages of simple structure and unique, with the good cooperation of the collapsible packing ring of a two formula, make the installation work of unilateral bolt very convenient and reliable, can improve the work efficiency of unilateral bolt installation by a wide margin to reduce the loss phenomenon that the multistage formula packing ring among the prior art easily appears.

Description of the drawings:

fig. 1 is a schematic perspective view of an embodiment of the present invention.

Fig. 2 is a schematic perspective view of another embodiment of the present invention.

Fig. 3 is the utility model discloses a spatial structure sketch map for installing unilateral bolt.

The specific implementation mode is as follows:

the detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings, and it should be noted that the detailed description of the embodiments is provided for the purpose of facilitating the comprehensive understanding of the technology of the present invention, and should not be construed as limiting the scope of the claims of the present invention.

Referring to fig. 1 to 3, the embodiment of the present invention is as follows: the mounting tool comprises an operating handle 1 and a long and thin cylindrical main body 2, wherein a clamping part which can keep a two-piece folding gasket which can be bent and deformed in a bent state is arranged at one end of the main body 2, and a connecting end 3 which is connected with a screw rod of a unilateral bolt is arranged at one end of the clamping part. Referring to fig. 3, in actual use, the two-piece foldable washer 9 is sleeved on the main body 2, the two-piece foldable washer 9 is formed by two semicircular washers to form a circular washer, a connection elastic member is disposed on an annular surface of the circular washer, the connection elastic member connects the two semicircular washers to form a circular washer, on one hand, the two semicircular washers can be bent at an angle and can be restored to a circular shape in a flattened state under the elastic force of the connection elastic member, the two-piece foldable washer 9 is bent, the contact surfaces of the two bent semicircular washers are matched with the clamping portions, so that the two bent foldable washers 9 are kept in a bent or constrained state, a screw 12 of a unilateral bolt is inserted into one side of a through hole 11 of a component 10 to be connected, and the connection end 3 of the installation tool with the two-piece foldable washer 9 is connected with the end of the screw 12, pushing the installation tool to move leftwards (arrow P direction) as the structure shown in fig. 3, after the two-piece foldable washer 9 to be bent passes through the through hole 11, rotating the operating handle or pressing down the main body 2, withdrawing the installation tool to remove the restraint on the two-piece foldable washer 9, unfolding the two-piece foldable washer 9 to be in a flat state, pulling the installation tool to move rightwards, exposing the end part of the screw rod 12 to the other side of the component 10 to be connected, matching the nut 13 sleeved on the main body 2 of the installation tool with the screw rod 12, taking down the installation tool, screwing the nut 13, and finally fastening the component 10 to be connected by the single bolt.
