Description

Anti-rotation positioning telescopic rod

The present invention relates to a telescopic rod, in particular to an anti-rotation positioning telescopic rod which is moved in a linear direction by a telescopic rod to achieve mutual positioning and mutual rotation.

According to the continuous improvement of industrial technology and the progress of the times, there are more and more types of hand tools, and hand tools must have the functions of being easy to carry and convenient to collect. Therefore, most of today's hand tools have the design of telescopic rods (ie, utilizing , the way the outer rod is sleeved), so that the hand tool can produce an extended or shortened work type, in order to increase the work convenience according to different use distances.

A telescopic rod for a hand tool disclosed in the present invention, which comprises a body, a rod body and a fixing device, the body having a working head and an extension rod, the extension rod being disposed on the rod Inside the body, the fixing device is installed between the body and the rod body, and has a set of knobs disposed outside the rod body and a torsion spring embedded between the rod body and the knob. When the knob is rotated, the torsion spring is outwardly expanded, and the tightening force of the torsion spring originally restrained on the extension rod is eliminated, and the body can be operated to expand and contract with respect to the rod body, when the knob is released When the power is turned, the elastic spring release force of the torsion spring itself can be used to tighten the extension rod and position the body relative to the rod body. Although the above structure can achieve the intended use, it still has the following disadvantages:

1. When performing the telescopic adjustment operation, the user must continue to apply force to the knob. If the knob is rotated with one hand, it is quite laborious. If one hand is held by the shaft, When the knob is rotated by another hand, the body is re-operated with respect to the rod body, and it is obviously difficult to perform the telescopic adjustment operation by a single person.

2. Since the body and the hoop of the rod are not positioned, the body may rotate relative to the rod when the hand tool is operated.
