After the sterilization is completed, the locking bar 7 is ejected to reset by pulling the locking piece 10 back to the inside of the locking seat 8 by unlocking the handle 9.
To sum up: the connection parts of the first pawl 33, the second pawl 34 and the sliding blocks 32 are respectively provided with a torsion spring, the deflector rod 35 is connected with the sliding blocks 32, when the deflector rod 35 is positioned on the central line between the two sliding blocks 32, the first pawl 33 and the second pawl 34 are respectively contacted with the ratchet wheel ring 31, when the deflector rod 35 is moved towards the first pawl 33, the sliding blocks 32 can drive the first pawl 33 connected with the first pawl to be far away from the ratchet wheel ring 31, and when the deflector rod 35 is moved towards the direction close to the second pawl 34, the sliding blocks 32 can drive the second pawl 34 connected with the second pawl to be far away from the ratchet wheel ring 31. When the screw needs to be locked, the ratchet mechanism 3 is arranged, the deflector rod 35 is stirred towards the direction close to the second pawl 34, at the moment, the first pawl 33 is in contact with the ratchet ring 31, the second pawl 34 is separated from the ratchet ring 31, when the handle 1 is rotated along the direction of locking the screw, the handle 1 drives the quick connecting sleeve 2 to rotate through the first pawl 33, the quick connecting sleeve 2 drives the screwdriver inserted in the quick connecting sleeve to lock the screw, when the handle 1 is reversely rotated, the first pawl 33 and the ratchet ring 31 deflect, the handle 1 cannot drive the quick connecting sleeve 2 to rotate, so that the screw cannot be driven to rotate during reversing, multiple looseness and grasping are not needed when the screw is locked, and only intermittent positive and negative rotation of the handle 1 is needed. Similarly, when the screw is removed, the lever 35 is moved in a direction approaching the first pawl 33, and at this time, the first pawl 33 is separated from the ratchet ring 31, and the second pawl 34 is brought into contact with the ratchet ring 31.
When the screw is locked, the handle 1 is reversed, and the first pawl 33 and the ratchet ring 31 deflect, so that the handle 1 and the quick connection sleeve 2 rotate relatively, a worker can drive the transmission shaft 51 to rotate through the relative rotation, the transmission shaft 51 drives the turntable 53 to rotate, the turntable 53 pulls the piston rod 56 to continuously reciprocate through the connecting rod 54 and the connecting seat 55, when the piston rod 56 is pulled out of the accumulator 57, the disinfectant in the liquid bottle 59 is pumped into the accumulator 57, and when the piston rod 56 is pushed into the accumulator 57, the disinfectant in the accumulator 57 enters the liquid spraying head 586 through the hose 581 and is sprayed out from the liquid spraying head 586, and the disinfectant is sprayed nearby the screw and the screw for disinfection. The windable metal tube 582 is a metal tube with a freely adjustable bending form, so that the liquid ejection angle of the liquid ejecting head 586 can be adjusted by the windable metal tube 582. If the spray head 586 is required to spray atomized disinfectant with smaller particles, the atomization baffle 585 is blocked in front of the opening of the spray head 586 by rotating the adjusting rod 583, and a plurality of small holes are formed in the atomization baffle 585, so that the disinfectant can be atomized when passing through.
The screwdriver is inserted into the quick-connect groove 21, and the magnet 61 attracts the end of the screwdriver to prevent slipping. When the spray head 586 is required to spray disinfectant to lock the screw, the handle 1 is pushed to the direction close to the screw, the screwdriver pushes the rotating shaft 63 through the push rod 62, the rotating shaft 63 drives the driving bevel gear 67 to move to the direction close to the driven bevel gear 52, the driving bevel gear 67 is finally meshed with the driven bevel gear 52, then when the handle 1 is reversely rotated to enable the handle 1 to relatively rotate with the quick connector 2, the incomplete gear 66 in the handle 1 drives the driving gear 65 to rotate, the driving gear 65 drives the rotating shaft 63 to rotate, the rotating shaft 63 drives the transmission shaft 51 to rotate through the driving bevel gear 67 and the driven bevel gear 52, power transmission is achieved, and the disinfectant is sprayed out through the disinfection mechanism 5. After the sterilization is completed, the screwdriver and the handle 1 are withdrawn, the rotating shaft 63 is reset by the elastic force of the reset spring 64, and the driving bevel gear 67 is separated from the driven bevel gear 52. The drive mechanism 6 is provided to drive the sterilizing mechanism 5 to sterilize as needed.
