The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The novel distal tube pre-cutting device shown in fig. 1 comprises a base plate 10, a cutter tool, a tube fixing cover plate 5 and a tube bracket 8; two vertical slide rails 7 are symmetrically arranged on the bottom plate 10 in a front-back manner, and the cutter tool is arranged between the two vertical slide rails, slides up and down relative to the vertical slide rails and is used for precutting the distal end tube placed on the bottom plate;

As shown in fig. 3, the cutter tool is composed of a left fixing block 2, a blade 3 and a right fixing block 1; the blade 3 is clamped between the left fixing block 2 and the right fixing block 1; the left fixing block 2 and the blade 3 are both fixedly arranged in a groove in the middle of the right fixing block 1; the two ends of the right fixed block 1 are provided with slide rail sliding blocks, the inner sides of the vertical slide rails 7 are provided with grooves, and the slide rail sliding blocks are inserted into the grooves and slide up and down along the grooves. In addition, the groove on the inner side of the vertical slide rail 7 extends upwards to the top end of the vertical slide rail, so that the cutter tool can be detached conveniently to replace the blade.

A pipe fixing cover plate 5 is arranged on the bottom plate at the right end of the vertical slide rail 7, one end of the pipe fixing cover plate 5 is connected with the upper end face of the bottom plate through a pin shaft, and the other end of the pipe fixing cover plate 5 rotates around the pin shaft and is connected with or opened and closed with the upper end face of the bottom plate; the movable end of the pipe fixing cover plate 5 protrudes outwards to form a locking buckle 11, and a clamping base 12 for clamping the locking buckle 11 is correspondingly arranged on the bottom plate. The fixed apron of tubular product 5 can place the distal end pipe on the bottom plate when being open mode, and closed fixed apron of tubular product 5 can compress tightly the distal end pipe on the bottom plate, avoids the distal end pipe to rock about the in-process of cutting in advance. In order to further enhance the compaction effect, a square groove is arranged on the inner side of the pipe fixing cover plate 5, and a pipe fixing rubber strip 6 with a matched shape is clamped in the square groove; the pipe fixing rubber strip 6 is used for applying soft pressure to the far-end pipe to avoid the pipe from being broken.

Because the distal end pipe is generally longer, the right-hand member of bottom plate 10 is provided with the tubular product and holds in the palm groove 8, and tubular product holds in the palm groove 8 and bottom plate 10 for detachable connections, is convenient for save and accomodates the space. The method specifically comprises the following steps: the right-hand member of bottom plate 10 is provided with convex T font fixed block 13, and the left end of tubular product support groove 8 matches and has seted up T font recess, and tubular product support groove 8 sets up in the right-hand member of bottom plate 10 through T font recess and the detachable that cooperatees of T font fixed block 13.

Two buffer springs 4 are symmetrically arranged on the front and back of the bottom plate right below the cutter tool; the interval between two buffer spring is greater than the length of blade 3 for go up the bullet to certain height with the cutter frock after cutting in advance and accomplish, avoid the blade to carry out the maloperation to the distal end pipe that cuts in advance. The rubber backing plate 9 is arranged on the bottom plate between the two buffer springs, so that the cutting force of the blade can be effectively buffered, and the bottom plate is prevented from being damaged by long-term use.

The left end of the base plate 10 is provided with an upwardly projecting baffle for aligning the distal tubes placed in rows so that the pre-cut length is uniform and controllable.

the utility model discloses a concrete theory of operation does:

Opening the pipe fixing cover plate 5, placing a plurality of distal end pipes on the pipe bracket 8 and the bottom plate 10 in a row, and enabling the left ends of the distal end pipes to be resisted on a baffle plate on the bottom plate 10; fastening the pipe fixing cover plate 5, wherein the using state is shown in figure 2; manually pressing down a cutter tool to pre-cut the distal tubes in batches; after the precutting is finished, the cutter tool is upwards bounced under the action of the buffer spring, and the precut distal end tube is taken out. After all the distal tubes are precut, the tube bracket 8 is vertically lifted upwards, so that the T-shaped groove and the T-shaped fixing block 13 are separated, and the storage space is saved.

Compared with the prior art, the utility model, following advantage has:

1) The method has the advantages that the pure manual operation is avoided, the pre-cutting speed is high, the efficiency is high, the batch operation can be realized, a large amount of labor cost is saved, and the working efficiency is obviously improved;
