Description

Reverse screw mounting and dismounting tool

Technical Field

The utility model relates to a mechanical tool technical field, concretely relates to reverse screw installation extracting tool.

Background

At present, no special tool is available for mounting and dismounting the reverse screw, two wrenches are needed to be matched simultaneously to complete mounting and dismounting of the reverse screw, and the reverse screw mounting and dismounting tool is low in efficiency and poor in practicability.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcoming that prior art exists, provide a reverse screw installation extracting tool.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a reverse screw installation extracting tool which characterized in that: including last spanner and lower spanner, it is equipped with the arc slide rail to go up between spanner and the lower spanner, the slide rail upper end is equipped with the arc and goes up the spout, the lower extreme is equipped with spout under the arc, go up spout and lower spout intercommunication, it can follow the gliding upper pulley of upper spout to be equipped with in the upper spout, be equipped with in the lower spout and follow the gliding lower pulley of lower spout, go up the spanner and connect the upper pulley through last connecting rod, lower spanner passes through lower connecting rod and connects the lower pulley, tip is equipped with the gyro wheel in the slide rail, wire rope is connected to the upper pulley lower extreme, the wire rope other end is walked around the gyro wheel and is connected the lower pulley upper end.

The utility model has the advantages that: the utility model is suitable for an installation and dismantlement when reverse screw can realize one-hand operation, and one-hand power, single direction power have improved work efficiency and operation security greatly.

Detailed Description

Example (b):

as shown in fig. 1 to 4, a reverse screw mounting and dismounting tool includes an upper wrench 1 and a lower wrench 2, an arc-shaped slide rail 3 is disposed between the upper wrench 1 and the lower wrench 2, an arc-shaped upper chute 4 is disposed at the upper end of the slide rail 3, an arc-shaped lower chute 5 is disposed at the lower end of the slide rail 3, the upper chute 4 is communicated with the lower chute 5, an upper pulley 6 capable of sliding along the upper chute 4 is disposed in the upper chute 4, a lower pulley 7 capable of sliding along the lower chute 5 is disposed in the lower chute 5, the upper wrench 1 is connected with the upper pulley 6 through an upper connecting rod 8, the lower wrench 2 is connected with the lower pulley 7 through a lower connecting rod 9, an idler wheel 10 is disposed at the inner end of the slide rail 3, the lower end of the upper pulley 6 is connected with a steel wire rope 11, and the other end of the steel wire rope 11 is connected with the upper end of the lower pulley 7 after bypassing the idler wheel 10.

During the use, aim at the nut of two reverse screws about with upper wrench 1 and lower wrench 2 and chucking, after firm after only need pull the handle of one of them spanner along slide rail 3 slip operation can, another spanner can be along slide rail 3 to the opposite direction slip under the effect of wire rope 11 to installation and dismantlement when realizing reverse screw.

The above-described embodiments are merely preferred and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.

In the description of the present invention, it is to be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the equipment or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
