Firstly, an operator pulls the destroying mechanism 3 to open, then the discarded syringe is placed on the placing seat 2, the needle cylinder is moved to a designated position by looking at the indicating plate 3012, then the destroying mechanism 3 is pulled to close and contact with the needle cylinder and the needle head, the destroying mechanism 3 is pushed to operate, the needle head is pushed out from the needle cylinder by the operation of the destroying mechanism 3, the pushed needle head is blocked by the first u-shaped baffle 4, the pushed needle head falls into the left collecting mechanism 5, the piston rod of the needle cylinder is broken by the continuous operation of the destroying mechanism 3, the broken piston rod falls into the right collecting mechanism 5, the destroying mechanism 3 can be released to reset, then the destroying mechanism 3 is pulled to open, the needle cylinder is taken down from the placing seat 2 and thrown into the right collecting mechanism 5, the destroying mechanism 3 is closed, thus, the discarded syringe can be destroyed, and the germ transmission caused by the fact that people pick up again and use the discarded syringe can be avoided, avoiding cross infection. When a proper amount of needles and syringes are arranged in the collecting mechanism 5, the collecting mechanism 5 can be pulled to move outwards to the outside of the frame body 1, then the needles and the syringes are taken out for treatment, and after the needles and the syringes are all taken out, the collecting mechanism 5 is pushed to reset.

Firstly, an operator pulls the handle 3011 to drive the swinging pressing block 301 to swing upwards, when the swinging pressing block 301 swings upwards to contact with the fixing plate 3013, the operator stops pulling the handle 3011, the injector can be placed in the placing seat 2, the needle cylinder is moved to a specified position through the indicating plate 3012, then the handle 3011 is pulled to drive the swinging pressing block 301 to swing downwards to reset, the swinging pressing block 301 resets to contact with the needle cylinder to press the injector tightly, at the same time, the push plate 305 contacts with the needle head, the operator pushes the push rod 307 to move downwards, the push rod 307 moves downwards to drive the wedge-shaped block 3010 to move downwards, the wedge-shaped block 3010 moves downwards to drive the movable rod 303 to move leftwards, the first spring 304 stretches, the movable rod 303 moves leftwards to drive the push plate 305 to move leftwards, the push plate 305 moves leftwards to drive the needle head to move leftwards to separate from the needle cylinder, the needle head falls into the left collecting mechanism 5, and at the same time, the push rod 307 moves downwards to drive the push plate 308 to move downwards, the second spring 309 is stretched, the material pushing plate 308 moves downwards to be in contact with a piston rod of the needle cylinder, the material pushing plate 308 breaks the piston rod of the needle cylinder, the broken piston rod falls into the right collecting mechanism 5, the push rod 307 can be released, the material pushing plate 308 moves upwards to drive the push rod 307 to move upwards to reset under the action of the second spring 309, the push rod 307 resets to drive the wedge block 3010 to reset, the movable rod 303 moves rightwards to drive the push plate 305 to move rightwards to reset under the action of the first spring 304, the handle 3011 pulls the swinging pressing block 301 to swing upwards to release the needle cylinder, and the needle cylinder is taken out and thrown into the right collecting mechanism 5.

When the syringe is pushed down by the push plate 305, the needle head falls into the left collecting frame 503, meanwhile, after the piston rod of the syringe is broken, the broken piston rod falls into the right collecting frame 503, meanwhile, an operator can throw the syringe with the broken piston rod into the right collecting frame 503, when a proper amount of needle head is arranged in the left collecting frame 503 or a proper amount of syringe is arranged in the right collecting frame 503, the operator can pull the limiting plate 506 to swing upwards to separate from the clamping plate 507, when the limiting plate 506 swings upwards to be in a vertical state, the collecting frames 503 on the left side and the right side can be pulled to move outwards to the outside of the frame body 1, then the needle head and the syringe are taken out for processing, after the needle head and the syringe are all taken out, the collecting frame 503 is pushed to move inwards to reset, and the limiting plate 506 is pulled to swing downwards to reset to be clamped on the clamping plate 507.

Example 2

Referring to fig. 4, the present embodiment is different from embodiment 1 mainly in that the present embodiment further includes an elastic member 7 and a material pushing rod 8, a guide slot 6 is formed in the middle of the left side of the top of the placing base 2, the material pushing rod 8 capable of pushing the needle cylinder is slidably disposed in the guide slot 6, and the elastic member 7 is connected between the bottom end of the material pushing rod 8 and the bottom of the guide slot 6.

When an operator puts the injector into the placing seat 2, the needle cylinder is in contact with the material pushing rod 8, the needle cylinder enables the material pushing rod 8 to move downwards, the elastic part 7 is compressed, the piston rod of the needle cylinder is broken, the operator pulls the handle 3011 to drive the swinging pressing block 301 to swing upwards to loosen the needle cylinder, the material pushing rod 8 moves upwards to push the needle cylinder to move out of the placing seat 2 under the action of the elastic part 7, and the needle cylinder falls into the right collecting frame 503. Therefore, the needle cylinder does not need to be manually taken down by an operator and is thrown into the right collecting frame 503, so that the operation is convenient and fast.

Referring to fig. 1, the frame further includes a second u-shaped baffle 9 and a fixture block 10, the fixture block 10 capable of fixing the limiting plate 506 is fixedly connected to the left side of the upper portion of the outer rear side of the first u-shaped baffle 4, and the second u-shaped baffle 9 is fixedly connected between the right sides of the top of the frame body 1.

When the limiting plate 506 swings upwards to be in a vertical state, the limiting plate 506 is clamped in the fixture block 10, an operator can loosen the limiting plate 506, start to pull the collecting frame 503 to move outwards to take out the syringe and the needle head for treatment, and pull the limiting plate 506 to be separated from the fixture block 10 for resetting after the collecting frame 503 moves inwards to reset. Meanwhile, when the piston rod is broken, the second u-shaped baffle 9 can block the burst piston rod. Therefore, the operator is not required to pull the limiting plate 506 all the time, time and labor are saved, and the second u-shaped baffle 9 can prevent the piston rod from bursting to the ground to affect the surrounding environment.
