It obtains and constitutes triangle fixed form between supporting element and handle, sleeve, play a supporting role to sleeve, operation simple with structure
Feature convenient, production cost is low.
Further preferably are as follows: the fixed device further includes adjustment seat, and the adjustment seat is threadingly attached to the branch
The one end of dagger far from the sleeve.
Using the above scheme, after support column stretches limit, handle may be not in fully horizontal state, the setting of adjustment seat
It can be carried out fine tuning, booster action played to support column, guarantee the horizontality of handle, and then reduce the deviation of torque value, drop
Low operation deviation, the mode of threaded connection are also convenient for dismantling, and can be carried out and are individually replaced if abrasion occurs in adjustment seat, reduce into production
Cost.
Further preferably are as follows: the adjustment seat is far from being fixedly connected with universal wheel on an end face of the support column.
Using the above scheme, universal wheel can be rolled in multiple directions, can adapt to pulling around axis in handle, simultaneously
Adjustment seat is directly abutted with ground or metope, reduces the abrasion of adjustment seat, reduces ground to being fixed the frictional force of device,
And then alleviate the active force that hand gives handle.
Further preferably are as follows: the side of the handle offers the accommodation groove for the fixed device receiving.
Using the above scheme, the setting of accommodation groove is not used or is transported in torque wrench convenient for the storage of fixed device
When defeated, fixed device is embedded in accommodation groove, prevents collision of the fixed device by foreign object, reduces the possibility of fixed device damage
Property.
Further preferably are as follows: the opening of the accommodation groove is provided with for covering the cover board for closing accommodating channel opening.
