Fixation apparatus e.g. sealing tool, for e.g. nail, has lever with catch expelling canon forwards by cooperating with shoulder for moving cannon from cartridge carrier even if cartridge case is wedged in combustion chamber of cannon

摘要

#CMT# #/CMT# The apparatus has a stop (26) and a lever (19) which is mounted pivoting around an axle (20) integrated with a case (16) and a cannon-carrier (3) in which a cannon (4) slides. The lever has a catch (23) expelling the canon forwards by cooperating with a thrust shoulder (22) of the cannon for moving away the cannon from a cartridge carrier (13) even if a cartridge case (12) is wedged in a combustion chamber (11) of the cannon. A cartridge (10) containing an explosive load is mounted a cartridge carrier which is received in the cannon-carrier. #CMT#USE : #/CMT# Used for driving a fixation insert e.g. nail, by an action of a combustion gas of an explosive load contained in a cartridge (claimed). #CMT#ADVANTAGE : #/CMT# The catch of the lever expels the cannon forwards by cooperating with the thrust shoulder for moving away the cannon from the cartridge carrier even if the cartridge case is wedged in the combustion chamber, thus facilitating a rapid opening of the apparatus after shooting of the cartridge without necessitating a high force of the operator to open the apparatus. The stop limits the course of the lever and prevents the lever from blocking against the canon during its return movement. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a fixation apparatus. 3 : Cannon-carrier 4 : Cannon 10 : Cartridge 11 : Combustion chamber 12 : Cartridge case 13 : Cartridge carrier 16 : Case 19 : Lever 20 : Axle 22 : Thrust shoulder 23 : Catch 26 : Stop.
