A kind ofly tighten the rapid ratchet spanners that loosens nut bolt by what rotor (1), ratchet (2) and moving arm (6) were formed, it is characterized in that rotor (1), ratchet (2) are installed in respectively in the macropore and aperture of housing (3), supporting plate (4) is installed in the groove of housing (3), two screws (5) are fixed between housing (3) and the supporting plate (4), moving arm (6) one ends are installed on ratchet (2) upper axis, the other end is positioned on the housing (3), and the pellet shot from a slingshot (7) and the spring (8) on ratchet (2) next door are installed in housing (3) the marble spring groove.
Ratchet is produced on the rotor lower ratchet axle, and square tenon is produced on rotor ratchet shaft top, and both are an integral body.
Ratchet is produced on the pawl axis, and in the upper end of pawl axis, is mounted with moving arm.
The housing left end is a semicircular structure, and the middle part partly is trapezoidal shape, and right-hand member then is a hollow cylinder.
The intersection point place of the vertical axis that is connected with the middle part at the housing left end and the cross central line of housing is equipped with rotor, and promptly rotor is installed in the macropore of housing.
Ratchet is installed on the cross central line of housing in the aperture, is positioned at the right side of rotor, and ratchet is engaged on the ratchet of rotor.
Pellet shot from a slingshot and spring are installed in the marble spring groove of housing, and pellet shot from a slingshot is pressed on the ratchet by spring.
Supporting plate is horizontal figure-8 structure metallic plate, the macropore of supporting plate in the left side is sleeved on rotor ratchet shaft top, and the aperture on right side is sleeved on the pawl axis, and whole supporting plate is installed and is placed on the housing left end and above the middle part in the groove, its effect is fixed ratchet wheel and ratchet, to prevent their axial motions up and down.
On supporting plate, two screws are installed, be used for fixing connection housing and supporting plate.
Moving arm one end is rectangular half-round cross hole, is sleeved on the pawl axis upper end, and the cursor other end is installed on the housing.
The ratchet spanner installation steps are as follows:
1, spring and pellet shot from a slingshot are installed in the bullet groove.
2, ratchet is installed in the aperture of housing.
3, the marble spring on rotor side's tenon is installed in advance after, again the rotor ratchet is installed in the macropore of housing.
4, supporting plate is installed in the enclosure slot, with the fixing rotor of the macropore on the supporting plate, with the aperture fixed pawl on the supporting plate.
5, with two screws housing and supporting plate are fixed together.
6, moving arm is installed in going up on the axle of ratchet tightly.
From above structure as can be known, the square tenon that rotor top makes can be inserted in the square hole of sleeve, after moving arm rotates, ratchet is rotated, thereby ratchet is rotated, and then the square tenon on ratchet shaft top rotates, and the nut in the end or bolt are tightened or unclamped in addition can to make sleeve.
The housing right-hand member is a hollow cylinder, in this columniform hollow circular hole, can insert tommy bar, and tommy bar can be inserted in the hollow circular hole of boosting-rod, after the other end side tenon of boosting-rod inserts sleeve, then can make its rotation and tightens or unclamp nut or bolt.
Originally tighten the rapid ratchet spanners that loosens nut bolt can be apace than other Wrench bolt, nut screwing clamping or loosen, and easy to operate, can positive and negative two-way use.
