micro torque tool

Abstract

The invention provides a small-torque tool. The small-torque tool comprises a body, a driving rod, a rotating rod and an elastic abutting device, wherein the driving rod is arranged in the body in a pivoted manner, the rotating rod is connected to the top end of the body, and the elastic abutting device is arranged in the driving rod and pushes the body; the rotating rod can move between the coaxial position and the storage position; when the rotating rod is at the coaxial position, a user is allowed to rapidly rotate the rod with fingers so as to achieve the effect that a work piece is rapidly rotated in a screw manner; and when the rotating rod is at the storage position, as the palm of the user cannot be obstructed by the rotating rod and can completely hold the body, and the center of the palm can be completely attached to the top edge of the body, force can be conveniently and easily applied, and the force applied with the wrist and the palm can be completely transmitted to the small-torque tool so as to achieve the effect that the work piece is twisted to be in the set torsion value; and the beneficial effect of decreasing the height of the small-torque tool is achieved, and the user can conveniently collect or carry the tool.

Description

technical field [0001] The invention relates to a micro torsion tool, especially a micro torsion tool capable of switching two operation modes. Background technique [0002] Referring to the U.S. Patent No. US7281457 "Wrenchwithadjustablemaximumoperationaltorque" patent case, it is a tiny torque wrench with adjustable torque. When checking the torque value, the user will find that it is difficult to continue to increase the force applied to the torque wrench simply by using fingers, so the screw cannot be further tightened, so that the screw that is screwed cannot reach the required torque setting value. question. [0003] In order to solve the above problems, users usually try to hold the torque wrench with the entire palm of their hand as much as possible, hoping to increase the turning force. It is difficult to fully transmit the force to the torque wrench, which leads to the loss of force applied to the wrist and palm, and even makes the user feel tingling or discomfor...

[0002] Referring to the U.S. Patent No. US7281457 "Wrenchwithadjustablemaximumoperationaltorque" patent case, it is a tiny torque wrench with adjustable torque. When checking the torque value, the user will find that it is difficult to continue to increase the force applied to the torque wrench simply by using fingers, so the screw cannot be further tightened, so that the screw that is screwed cannot reach the required torque setting value. question

[0003] In order to solve the above problems, users usually try to hold the torque wrench with the entire palm of their hand as much as possible, hoping to increase the turning force. It is difficult to fully transmit the force to the torque wrench, which leads to the loss of force applied to the wrist and palm, and even makes the user feel tingling or discomfort in the palm. Finally, the user can only turn the torque wrench with both hands at the same time to make the screw possible. Achieve the result of real locking to the required set torque value

[0004] However, the two-handed operation also constitutes a trouble for the user. The alternating process of one-handed operation and two-handed operation has formed an inconvenient result, which in turn affects consumers' desire to purchase this product, and greatly damages the goodwill of the product.
