The card slot that card 26 is caught in, the torsional spring adjustment ratchet 20 are sandwiched between two Spring Cards 26, offer blind hole on the main shaft 4, excellent
Blind hole is selected to open up along the radial direction of main shaft 4, the little spring 23 and ratchet 21 are set in blind hole, and described 23 one end of little spring is butted on
Blind via bottom, the other end are butted on ratchet 21；The ratchet 21 is meshed with the internal tooth of torsional spring adjustment ratchet 20, so that torsional spring tune
Whole ratchet 20 can only single direction rotation.It is preferred that there is tool slot 20b on torsional spring adjustment 20 external circumferential face of ratchet, when needing to adjust
When the torsion of torsional spring, be stuck on tool slot 20b using tool and rotate torsional spring adjustment ratchet 20, due to one end of torsional spring fixes (or
Overlap joint) in torsional spring fixed plate 9, it (is fixed on torsional spring adjustment ratchet 20) in other end insertion insertion hole 20a, therefore rotates and turn round
Spring adjusts ratchet 20 then and the torsion of torsional spring can be changed, and side gradually adjusts frontier inspection and surveys until reaching requirement, once adjustment is excessive
(rotation torsional spring adjustment 20 degree of ratchet is big), then can adjust the Spring Card 26 of 20 side of ratchet, by torsional spring by removing torsional spring
Axial direction of the adjustment ratchet 20 along main shaft 4 and the direction far from torsional spring pull a distance to make torsional spring adjustment ratchet 20 disengaging and ratchet
Then 21 engagement resets torsional spring adjustment ratchet 20, on card so that torsional spring adjustment ratchet 20 sheds the constraint to torsional spring
Spring Card 26, such torsional spring adjustment ratchet 20 and torsional spring restore to initial conditions, so as to again to torsional spring adjust ratchet 20 into
Row adjusts and then adjusts the torsion of torsional spring, can also use further with regards to torsional spring adjustment ratchet 20 is detached from engaging for ratchet 21
Following methods, is not limited only to this.

On main shaft 4, a small lever is formed；In the groove 21a of one end insertion 21 side of ratchet of the ratchet clawback part 22.When passing through work
When tool upwarps the other end of ratchet clawback part 22, the bullet for driving ratchet 21 to overcome little spring 23 is set aside in one end of ratchet clawback part 22
Power is detached to bottom offset and adjusts engaging for ratchet 20 with torsional spring, and torsional spring adjusts the return under torsional spring drive of ratchet 20, thus
It is convenient that torsional spring adjustment ratchet 20 is adjusted again.The advantages of this mode, is, when resetting torsional spring adjustment ratchet 20,
Without removing Spring Card 26.
Preferably, the torsional spring adjustment ratchet 20, ratchet 21, little spring 23 and torsional spring 8 are two, are symmetrically disposed on master
On axis 4.It is preferred that the two sides of each torsional spring adjustment ratchet 20 all have a Spring Card 26, i.e., totally 4 Spring Cards 26, torsional spring adjust
The effect of 20 two sides Spring Card 26 of ratchet is to constrain the axial displacement of torsional spring adjustment ratchet 20, prevents torsional spring adjustment ratchet 20 de-
Position.
