Description

Adjustable two-way torque wrench

The present invention relates to an adjustable two-way torque wrench, in particular to a combination of an adjustable and fixed torque wrench, a connecting portion and a sleeve capable of changing the clamping area.

The conventional wrench is designed as a combination of a handle and a head that can be fixed with a screw. When in use, the force is applied to the handle to generate a torque, and the screw of the head fixing is rotated to screw the screw into the screw. The object is locked, and the threaded portion is embedded and fixed to the locked object. However, when using the wrench, the force can only be judged by subjective judgment, and the objective data is not available to the user to know the magnitude of the torque, so when different When the user uses the same wrench, the result will be unpredictable due to different force applied. It may be because the force is too large and the screw is weakened or the force is too small, so the screw is not tightened. Therefore, the manufacturer has designed the adjustable and Torque wrench for reading torque; the torque wrench of the saw is designed to use the adjusting handle to drive the screw to rotate in the shank, so that the pushing block moves up and down in the direction of its rotation, so that the index moves to the positioning under the driving of the pushing block and The torque value is indicated so that the user can interpret and adjust the torque. However, the user often accidentally turns the handle when using the wrench, and the torque value will not change as the handle rotates. , Causing the user can not use it to set the torque to work; the bottom of the wrench design of this creator has a fixed torque lock, when the fixed torque when tightened to lock the torque wrench fixed to address the problem of the aforementioned torque change.

The conventional sleeve has different internal shapes of 4, 6 and 12 angles and different specifications such as 1/4 inch, 3/8 inch and 1/2 inch. The user faces different shapes and sizes. The screw and the valve must use different sleeves, so the user often has to carry a considerable variety of types and sizes of sleeves to correspond to different screws and valves. Therefore, the manufacturer has designed a three-jaw sleeve; The three-jaw sleeve is in contact with the gear wheel of the center by three rotating members, and the three rotating members are rotated in the opposite direction via the rotation of the gear wheel, so that the spacing of the clamping members at the front end of the rotating member is changed to expand Or reduce the effect of the sleeve area, so a three-jaw sleeve can correspond to various types of screws and valves, however, the contact area of the three-jaw sleeve with the screw and the valve is small, so It is often worn out and unbearable, and it is easy to cause deformation of the screw and the valve. The sleeve of the sleeve designed by the creator has a protective sleeve at the front end to solve the problem of wear of the clamp and damage of the screw and the valve.

Conventional wrenches and sleeves do not have a single specification. Users need to go through several tests to find the engageable wrench and sleeve. After the joint, the wrench and the sleeve are often difficult to fix or separate. The creator designed one. The connecting rod is used to combine the sleeve of the design with the wrench and is fixed by the ball at the joint, which makes it easy to assemble or separate, and is very convenient to use.

The main purpose of this creation is to provide an adjustable two-way torque wrench, which can improve the shortcomings of the torsion wrench caused by the accidental touch of the handle, and the disadvantage of the three-claw sleeve being easy to wear, and solving the sleeve and The problem of connecting the handles.

In order to achieve the foregoing objective, the present invention provides an adjustable two-way torque wrench, comprising a sleeve, a connecting rod and a wrench; the sleeve comprises a baffle and a base, the base has a first receiving hole and one side is connected There is a gear turntable and three transmission members, and each of the transmission members has an clamping member. When the gear turntable rotates, each of the transmission members is rotated in the opposite direction, so that the distance between the clamping members is changed, so that the clamping members sandwich different sizes of valves; the connecting rod includes one side having a a first protruding portion of the first ball and a second receiving hole, and the first protruding portion is in contact with the first receiving hole of the sleeve and fixed by the first ball, the sleeve can be engaged with the connecting rod; The wrench includes a wrench head, a handle and a grip portion, the wrench head has a second protrusion with a second ball on one side, and the second protrusion and the second receiving hole of the connecting rod After being connected and fixed by the second ball, the wrench can be engaged with the connecting rod, and the bottom of the grip portion is provided with a torque fixed lock, and the value of the torque can be from the top of the grip portion, and the scale is connected with the handle.
