The other end of the activity handle connects transmission rod；The transmission rod is in handle cage；The other end of the transmission rod is upward
Head cage is extended to, and connects pawl；The transmission shaft is arranged in head cage；One end of the transmission shaft passes through thrust
Spring is connected in head cage；It is disposed with ratchet since thrust spring end, on transmission shaft, rotates forward cone pulley, reverse cone
Wheel, retaining spring ball and localization handspike；The localization handspike is exposed to outside head cage；Retaining spring is provided in head cage
Ball detent；Cone pulley is provided between the rotating forward cone pulley and reverse cone pulley；Screw work head is provided on the cone pulley.
Preferably, the end of the movable handle is provided with contracting power spring, and contracting power spring is arranged in handle cage.
Preferably, rolling bearing is provided in the screw work head.
Preferably, drive bearing is provided on the transmission shaft.
Preferably, the transmission rod uses double rocker mechanism.
Preferably, reset spring is provided between the transmission rod and pawl.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages:
A kind of mechanical automatic screwdriver of the present invention program is transmitted using human body grip as motive power by mechanical structure
With amplification power, it can reach efficient parbuckle screw and be not required to be powered, energy-saving and environment-friendly purpose, and manually control securely and reliably, it avoids
Accident occurs, while guaranteed efficiency, also safety and environmental protection.
Detailed description of the invention
Technical scheme of the present invention is further explained with reference to the accompanying drawing:
Attached drawing 1 is a kind of partial sectional view of the winding supporting insulator of dry-type transformer of the invention；
Attached drawing 2 is a kind of partial sectional view of the high-voltage winding mounting structure of dry-type transformer of the invention；
Wherein: 1, handle cage；2, head cage；3, force transmission mechanism；4, screw work head；31, movable handle；32, it passes
Power bar；33, pawl；34, ratchet；35, transmission shaft；36, thrust spring；37, cone pulley is rotated forward；38, cone pulley is reversed；39, bullet is positioned
Spring ball；40, localization handspike；41, retaining spring ball detent；42, cone pulley；43, contracting power spring；44, rolling bearing；45, transmission shaft
It holds；46, reset spring.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
Attached drawing 1-3 is a kind of mechanical automatic screwdriver of the present invention, including handle cage 1, and head cage 2 passes
Force mechanisms 3 and screw work head 4；The top of handle cage 1 is arranged in the head cage 2；The force transmission mechanism 3 includes: work
Dynamic handle 31, transmission rod 32, pawl 33, ratchet 34 and transmission shaft 35；One end of the activity handle 31 is arranged in head cage 2
On；The other end of the activity handle 31 connects transmission rod 32；The transmission rod 32 is in handle cage 1；The transmission rod 32
The other end extend up to head cage 2, and connect pawl 33；The transmission shaft 35 is arranged in head cage 2；The biography
One end of moving axis 35 is connected in head cage 2 by thrust spring 36；Since 36 end of thrust spring, on transmission shaft 35 successively
It is provided with ratchet 34, cone pulley 37 is rotated forward, reverses cone pulley 38, retaining spring ball 39 and localization handspike 40；The localization handspike 40 reveals
In outside head cage 2；Retaining spring ball detent 41 is provided in head cage 2；The rotating forward cone pulley 37 and reverse cone pulley 38
