Description

Technical Field

[0001] The utility model relates to the technical field of torque tools, and more specifically to a digital-display torque handheld screwdriver. Background Art

[0002] A torque screwdriver is also called a torque screwdriver. It is a screwdriver with a torque value. The torque value can be preset. When the fastener being screwed reaches the preset torque value, the clutch inside the screwdriver automatically disengages, making a "click, click, click..." sound, and you can feel this movement by hand. At this time, even if you continue to increase the force, it will not exceed the preset limit.

[0003] At present, with the advancement of technology, in order to make the use of torque screwdrivers more labor-saving and convenient, many types of digital torque screwdrivers have appeared on the market, which can not only display the torque value, but also be driven by electricity, making them more labor-saving to use. However, most of the existing digital torque screwdrivers can usually only install one screwdriver head, which is screwed perpendicular to the fastener. It is not only difficult to use with screwdriver heads of different specifications, but also cannot be used in a smaller space because it is screwed perpendicular to the fastener.

When the fastener is tightened, the torque value is set through the digital display device 11, and the electric handle 1 controls the active bevel gear 5 to rotate. The active bevel gear 5 drives the vertical connector 3 to rotate, and at the same time drives the multiple driven bevel gears 6 to rotate. The multiple driven bevel gears 6 respectively rotate the multiple side connectors 4. The cutter heads connected to the vertical connector 3 and the multiple side connectors 4 can be selected in a variety of ways according to actual conditions, and have a wide range of applications.
