In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an injection skid-proof needle tubing syringe, including the stock solution cover that is used for storing the medicament, control medicament input/output push away the handle and connect the stock solution cover with push away the core bar of handle, the internally mounted of stock solution cover has the one end of core bar, the other end of core bar is fixed with and pushes away the handle, the one end outside both ends of stock solution cover are fixed with the non slipping spur, the other end of stock solution cover is fixed with the spacing piece, the central point of stopper puts and has seted up spacing hole, through spacing hole the inside of stopper runs through perpendicularly and is provided with spacing connecting rod, the one end that spacing connecting rod runs through the stopper passes through the connecting block that plastics fixedly connected with size is.

Preferably, a press hand is arranged between the adjacent limiting blocks, and the press hand and the limiting blocks are fixed at one end of the liquid storage sleeve at equal angles.

Preferably, the antiskid blocks are arranged in two groups, the antiskid blocks are symmetrically arranged about the central axis of the liquid storage sleeve, and the antiskid blocks and the limiting blocks are distributed on the outer side of the liquid storage sleeve in an intersecting and equal-angle mode.

Preferably, the radius of the limiting hole is slightly larger than that of the limiting connecting rod, the limiting connecting rod and the pushing handle are of an integral structure, and the length of the limiting connecting rod is smaller than that of the core rod.

Preferably, the upper layer and the lower layer of the connecting block are both in a round platform shape, and the connecting block is connected with the limiting connecting rod through a plastic material.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses, through set up the non slipping spur in stock solution cover outside one end, can prevent operator hand-held device, when the device landing, can make device one end card between user's hand through the non slipping spur, can not drop subaerially.

2.
