Preferably, a limiting rod is fixedly arranged on one side of the pawl inside the screwing block, and the rotatable reverse direction of the pawl can be limited through the limiting rod.
Preferably, the rotating shaft where the pawl is located is provided with a torsion spring, and the pawl can be conveniently helped to reset through the torsion spring, so that the pawl can use a clamping ratchet wheel.
Preferably, the clamping groove has all been seted up to rolling disc outside surface four corners department, it is provided with the elasticity card to twist the fixed surface in the piece upper end outside, elasticity card activity block sets up inside the clamping groove, blocks the clamping groove through the elasticity card, can rotate 90 degrees after the rolling disc and play the fixed action.
Preferably, the middle part of the upper end of the rotating disc is fixedly provided with a shifting piece, and the rotating disc can be further conveniently rotated through the shifting piece.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses can rotate the rolling disc through the plectrum when twisting and moving, can anticlockwise or clockwise rotation rolling disc 90 degrees as required, thereby make the rolling disc drive the stripper bar and rotate, then can extrude the pawl of one side through the stripper bar and rotate around rotating, make the pawl no longer block the ratchet, twist this moment and move the piece and just can only rotate towards a direction, it is dead just to lock when twisting a convenient rotation, so can make things convenient for the staff to twist the device body, thereby need not every twist the round and just take off the spanner from twisting a outside surface and reset and twist the round again.
2. The utility model discloses when using, elasticity card activity block sets up inside the draw-in groove, blocks the draw-in groove through the elasticity card, can rotate 90 degrees after the rolling disc and play the fixed action, can further conveniently rotate the rolling disc through the plectrum.
