Some butterfly shell fragments,
Upper ratchet, described upper ratchet lateral wall is provided with the projection that several protrude from ratchet lateral wall, the lining being fixed on handle hollow housing madial wall is provided with outside described upper ratchet, described lining madial wall offers is convenient to described projection along connecting rod axially-movable and some guide grooves of rotating of the upper ratchet circumference of restriction
Bottom ratchet wheel, the teeth of described bottom ratchet wheel are meshed with the teeth of upper ratchet, and described bottom ratchet wheel is fixedly connected with connecting rod by steady pin, and
Adjusting nut, described adjusting nut is used for butterfly shell fragment, upper ratchet and bottom ratchet wheel to compress.
In order to eliminate alignment error further, between described bottom ratchet wheel and adjusting nut, be also provided with miniature thrust ball bearing.
In order to cut off inner for spanner to protect spanner inner with the external world, described connecting rod is also arranged with the end cap for being closed by handle openings end.
As preferably, between described end cap and connecting rod, be provided with sealing ring.
In order to the motion of convenient upper ratchet, described projection is steel ball.
As preferably, described some upper and lower both sides of butterfly shell fragment are respectively provided with a pad, and described pad is set on connecting rod.
As preferably, described handle is aluminum handle.
As preferably, described handle lateral wall is provided with the hatching knurling increasing frictional force.
In order to increase the frictional force of handle lateral wall further, described handle lateral wall is evenly equipped with some grooves.
The beneficial effects of the utility model are: a kind of torsion restriction spanner that the utility model provides, and by using some butterfly shell fragments to replace Compress Spring, elasticity stable, not easily deformation failure, the torsion of torque spanner can be made to obtain and keep; Between bottom ratchet wheel and adjusting nut, be provided with miniature thrust ball bearing, eliminate alignment error, improve production efficiency; Handle lateral wall is provided with hatching knurling and some grooves, adds the frictional force of handle, improves security and the high efficiency of operation use.
