Preferably, gland intermediate openings; Pointer round end place is fixed in opening, and tip place is through dial indication numerical value.
Preferably, handle outer is surrounded by anti-skidding plastic cover; Thereby prevent because of the torque spanner that drops that skids for increasing hand friction.
Preferably, the junction of fork and support arm is that circular arc is smoothly connected, and fork is that smooth transition is connected with the junction of handle.
Preferably, the torque value scope that dial shows is 0～300Nm.In the utility model, because fork is connected with torsional axis, and torsional axis is coaxially connected with gland, while therefore working, the hexagonal Zhi of carrying torsion passes to gland by torsional axis by moment of torsion, the pointer that driving is connected with gland carries out index, and the position that pointer pointed on degree of coiling at quarter is torque value.
The pointer type torque spanner that the utility model provides, tool has the following advantages:
1. this apparatus structure is simple, volume is light and handy, easy to use;
2. this device improves end construction to be designed to sleeve head structure, can carry the hex bolts hole of 4 kinds of different sizes simultaneously, and collet head is dismountable pivot pin structure, mean and can detect and need to replace at any time the collet head of more specifications according to reality, can fully meet the torsion detection demand that communication iron tower tightens firmware;
3. this device can alleviate the weight of Portable device, can improve again the efficiency that communication iron tower detects operation, has extremely strong applicability.
