Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 and 2, an adjustable tightening tool includes a clamp handle 1, a first handle 2, a fixed clamp portion 3 and a movable clamp portion 4; the fixed clamp part 3 is vertically arranged at one end of the clamp handle 1, and the first handle 2 is coaxially arranged at the other end of the clamp handle 1; the movable clamp part 4 is sleeved on the clamp handle 1, the movable clamp part 4 is provided with a rotatable worm 5, and a plurality of teeth 6 are uniformly distributed on one side of the clamp handle 1 and are meshed with the worm 5; the front end of the fixed clamp part 3 is provided with a positioning upright post 7; the front end of the movable clamp part 4 is provided with a clamping upright post 8; the movable jaw part 4 is also provided with a locking threaded pin 9.

The working principle of the adjustable tightening tool in the embodiment is as follows:

the worm 5 is rotated, the worm 5 is meshed with a plurality of teeth 6 on the clamp handle 1 to rotate, so that the movable clamp part 4 moves towards the direction close to the fixed clamp part 3 or away from the clamp part along the clamp handle 1, when the movable clamp part 4 moves to clamp conventional threaded fasteners such as bolts, screws or nuts with the fixed clamp part 3, the locking threaded pin 9 is screwed, the movable clamp part 4 is fixed on the clamp handle 1, and then the first handle 2 is pulled to screw or unscrew the threaded fasteners such as the bolts, the screws or the nuts; when the movable clamp part 4 moves to the position upright post 7 and the clamping upright post 8, the distance between the two hole groove structures on the screw cap is the same, the locking threaded pin 9 is screwed, the position upright post 7 and the clamping upright post 8 are respectively inserted into the two hole groove structures on the screw cap, and then the screw cap can be screwed down or unscrewed by pulling the first handle 2.

In one embodiment, a second handle 10 is coaxially disposed at one end of the forceps handle 1.

In this embodiment, when the threaded fastener such as a bolt, a screw, or a nut is screwed tightly, the first handle 2 is pulled only to loosen the threaded fastener, and the second handle 10 is added to increase the force for tightening or loosening the threaded fastener, so as to achieve the fixing effect of the threaded fastener; when used to tighten or loosen a screw cap having a hole and groove structure, the position requirement of the adjustable tightening tool is relatively high, and the position of the adjustable tightening tool can be well balanced by adding the second handle 10 and holding the first handle 2 and the second handle 10 with both hands, respectively, to achieve quick and reliable tightening or loosening of the screw cap.

In one embodiment, a third handle 11 is vertically disposed at one end of the forceps handle 1.

In this embodiment, the main function of adding the third handle 11 is to position the positioning column 7, and when adjusting the distance between the clamping column 8 and the positioning column 7 and during screwing or unscrewing the screw cap with the hole-groove structure, the third handle 11 can well fix the positioning column 7, so that the process of adjusting the distance or screwing is more smooth.

In one embodiment the movable jaw part 4 is provided with a fourth handle 12 in parallel with the third handle 11.

In this embodiment, the fourth handle 12 is mainly used to assist the movable handle to move along the forceps handle 1 by the fourth handle 12 when the worm 5 is rotated.

In one embodiment, the second handle 10, the third handle 11, and the fourth handle 12 are all removably attached.

In this embodiment, the detachable design structure enables the adjustable tightening tool to be stored and transported conveniently, and when a large amount of tightening tools are needed for certain types of tightening work, the second handle 10, the third handle 11 or the fourth handle 12 can be detached or installed as needed, so that the work is more comfortable.

In one embodiment, the first handle 2, the forceps handle 1, the fixed forceps part 3, the second handle 10 and the third handle 11 are of an integrally formed structure.

In this embodiment, the partial structure design of screwing up the instrument with adjustable becomes integral type structure, mainly increases to consider structural strength, increase of service life, and when the whole light and volume of screwing up the instrument with adjustable is less, its partial structure suitably adopts integral type structure.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
