When the movable handle 30 is pulled forward, that is, the movable handle 30 needs to be separated from the normal working state, the trigger type locking structure is converted from the first characteristic part 311 to be tightly abutted against the second characteristic part 312, the slider 10 leaves the first sliding groove 22, and the slider 10 forms a fixed angle with the main body 20 under the limiting action of the trigger type locking structure, at this time, the vertebral plate rongeur is in a disassembly state.
Further, in the present embodiment, the trigger type locking structure is sequentially provided with the first sliding portion 41, the second sliding portion 42 and the trigger portion 40 from left to right, so that during actual production and manufacturing, in order to facilitate molding and disassembly, the part of the structure can be integrally molded, and the stability of the whole component is also improved; when the vertebral plate rongeur is in a working state, the first sliding part 41 is abutted against the first characteristic part 311 of the movable handle 30; when the vertebral plate rongeur is in a disassembled state, the first sliding part 41 is tightly abutted against the second characteristic part 312 of the movable handle 30, and the trigger part 40 is connected with the rear end of the sliding block 10, so that the sliding block 10 and the main body 20 form a fixed angle. More specifically, an arc boss 31 is formed on the rear end face of the upper portion of the movable handle 30 in a protruding manner, and the lower surface of the arc boss 31 is in arc transition connection with the rear end face of the movable handle 30 to form the first feature portion 311; the upper surface of the arc boss 31 is in arc transition connection with the rear end face of the movable handle 30 to form the second characteristic part 312; the first sliding portion 41 can move and abut on the first feature portion 311 or the second feature portion 312. Overall structure rotates trigger portion 40 gently when the cleaning condition, makes slider 10 rear portion place in under trigger portion 40, then loosens trigger portion 40, under the trigger portion 40 effect, just can be spacing to the cleaning condition with slider 10 for rongeur can keep fixed angle open at the cleaning condition, and then makes it can not be closed unusually in the cleaning process, changes and washs disinfection and isolation, and it is more convenient to use.
Further, in the present embodiment, the trigger type locking structure includes a trigger member 43, a trigger screw 70 and a torsion spring 60 sleeved on the trigger screw 70, the trigger member 43 is in clearance connection with the body 20 through the trigger screw 70, the trigger member 43 can rotate around the trigger screw 70, the chin portion of the body 20 is provided with a hollow area, the torsion spring 60 is disposed in the hollow area, and the trigger screw 70 penetrates from one side of the chin portion of the body 20 to the other opposite side of the chin portion of the body 20. Specifically, the trigger member 43 includes a trigger portion 40, the trigger portion 40 is a key-shaped member, the upper surface of the trigger portion 40 is a plane, so that the thumb of the user can be conveniently contacted with the plane arranged on the upper surface of the trigger portion 40, and the force applied to the trigger portion 40 is further facilitated, so that the structure can be operated by one hand when in use, and is very convenient, one end of the trigger portion 40 close to the movable handle 30 extends towards the movable handle 30 to form a third boss 44, the end surface of the third boss 44 contacted with the movable handle 30 forms the first sliding portion 41, the arc-shaped surface arranged at the lower portion of the third boss 44 towards the inside of the third boss 44 forms the second sliding portion 42, the first sliding portion 41 is abutted to the first characteristic portion 311 or the second characteristic portion 312, and the second sliding portion 42 is abutted to the torsion spring 60. The trigger member 43 is connected with the main body 20 through a torsion spring 60, the trigger member 43 limits the movable handle 30, the trigger member 43 automatically resets by means of the torsion spring 60, and then the movable handle 30 is limited again, so that one-key reset of the rongeur can be realized, the cleaning does not need to be disassembled and assembled, the part does not have the risk of loss, and the state is switched by one key.
Specifically, when the vertebral plate rongeur is in an operating state, the first sliding portion 41 abuts against the upper edge of the first feature portion 311 of the movable handle 30, and the user continues to press the handle, so that the first sliding portion 41 slides at the first feature portion 311 of the movable handle 30, and finally abuts against the upper edge of the first feature portion 311 of the movable handle 30, and the first boss 11 arranged on the slider 10 is in the first sliding groove 22 of the main body 20, so that the sliding rod is driven to slide back and forth at the upper end of the main body 20 when the handle is operated. When the vertebral plate rongeur needs to be switched from the working state to the disassembly state, a user releases the movable handle 30, presses down the trigger member 43, the first sliding portion 41 and the first characteristic portion 311 slide to the second characteristic portion 312 separately, meanwhile, the second sliding portion 42 abuts against the end portion of the torsion spring 60, and presses the torsion spring 60, when the first boss 11 at the rear portion of the slider 10 is separated from the first sliding groove 22 at the rear portion of the main body 20, because the movable handle 30 is connected with the slider 10, the movable handle 30 rotates clockwise and drives the slider 10 to translate backwards, the slider 10 continues to move backwards until reaching the limit position, and then the slider rotates clockwise around the connection portion with the movable handle 30 until forming a fixed angle with the main body 20. By rotating the trigger, then rotating the slider 10 and then opening the trigger at a certain angle, the rongeur can be switched from a normal working state to a disassembly cleaning state. The angle between the sliding block 10 and the main body 20 is restored, the handle 30 is rotated to enable the torsion spring 60 to rebound, and the trigger is reset, so that the rongeur can be switched from the disassembly cleaning state to the normal working state.
Further, in this embodiment, a limit pin 80 is further disposed in a hollow region of the cheek portion of the body 20, the limit pin 80 is connected in a limit hole of the body 20 in an interference manner, the limit pin 80 is disposed below the first sliding portion 41, an axis of the limit pin 80 is parallel to an axis of the trigger screw 70, one end of the torsion spring 60 abuts against the limit pin 80, so that the torsion spring 60 is in a stressed state, and the other end of the torsion spring abuts against the second sliding portion 42; when the vertebral plate rongeur is in a working state, the limiting pin 80 abuts against the lower part of the first sliding part 41, so that the first sliding part 41 abuts against the first characteristic part 311.
