Abstract
The utility model discloses an electronic warner for torgue force spanner, belonging to vehicle maintenance tools, which is an improved spanner comprising a connecting head, a finger, a dial, and a handle. The utility model is characterized in that an electronic alarm device is arranged in the handle, and an alarm contact is arranged on the dial. When the finger contacts the arranged contact causing by torsion, sounding beep, and stops pressing. The spanner can accurately twist the workpieces solving the working environmental limit of daytime or night. The utility model has the advantages of simple operation, convenient operation and high precision.
Description
The utility model belongs to vehicle maintenance tool.
When car assembling and repairing, for the assembling of various fasteners, the moment requirement need be arranged, the moment torque spanner is the instrument of using always.This instrument is to observe the swing position of pointer on calibrated disc by the operator to determine that its torsion reaches requirement not, as if be difficult to see clearly its beat of pointer position at night.
The purpose of this utility model provides a kind of torque spanner that is easy to nighttime operation.
The utility model main points are:
To be improved by the moment torque spanner that connector, pointer, calibrated disc and handle are formed, it is characterized in that electronic alarm device is housed in handle, calibrated disc is provided with alarm actuating contact.When torsion made pointer run into the contact of setting, warning device was sounded a buzzer, and stops reinforcing.
After the utility model occurs, make the operator be not subjected to daytime or night working environment restriction, can both tighten workpiece exactly, it has simple to operate, and is easy to use, the accuracy advantages of higher is easy to utilize.
