Specific embodiment

The utility model is as shown in Figs. 1-5, including pen container 1 and in pen container 1 and extends to the syringe needle 2 outside pen container 1, The bottom of the pen container 1 is equipped with opening 11, and the syringe needle 2 runs through the opening 11,

From edge to central reduction, tapered, the inside top of the pen container 1 is equipped with spring 3, institute for 1 bottom of pen container State 3 connecting needle of spring, 2 top；

It further include baffle 4 and limit for height block 5, the baffle 4 is set in 2 lower part of syringe needle and is arranged in bottom in pen container 1, described Limit for height block 5 is set to 11 edges of opening, and the limit for height block 5 is used to support pen container 1 and control rubber quality；

The pen container 1 is provided with colloid 6.When in use, pen container is held, needle resists place to be applied, pushes, syringe needle It remain stationary, pen container can move downward, and after limit for height block resists frame, movement stops, and baffle moves upwards relative to pen container, makes It obtains and generates gap between baffle and pen container inner wall, in this way, colloid is moved downward through gap under the effect of gravity, thus full of gear Plate and opening are formed by cavity；It is equipped with spring between pen container and syringe needle, starts energy storage in spring, the descending motion of pen container is more Add steady, too fast movement will not be generated, and limit for height block is caused to clash frame, in this way, operation is more stable, reliable, meanwhile, When starting dispensing, hand-held pen container is moved upwards, and under the effect of spring force, promotes the rising of pen container, at this point, baffle is opposite Pen container moves downward, so that the cavity between baffle and opening becomes smaller, is open in this way, colloid will be extruded by baffle, needle of postponing Head reaches frame, further, by adjusting the height of limit for height block, so that it may which the shift length for controlling pen container also just controls The size of cavity between baffle and opening, the glue amount for also allowing for outflow pen container is controllable, while but also colloid in pen container Keep certain mobility；Pen container bottom is from edge to central reduction, tapered, and pen container consists of two parts, and a part is straight Tubular, a part are cone cells, in this way, generating gap between Cai Huiyu pen container, it is ensured that colloid can flow after baffle rises with respect to pen container Out.

The length of the syringe needle 2 is less than the height of pen container 1.In this way, avoiding syringe needle too long, so that spring is being fully compressed Afterwards, limit for height block is also not up to frame position, it is ensured that limit for height block reliably plays the role of control rubber quality.

The syringe needle 2 is equipped at least a pair of of plectrum 21, and a pair of plectrum 21 is arranged in inverted V type, several plectrums 21 symmetrically set up, and the plectrum 21 is located in pen container 1.A pair of of plectrum is arranged in inverted V type, that is to say, that plectrum is towards pen container bottom Portion's inclination, in this way, plectrum is moved downward with respect to pen container in pen container uphill process, plectrum squeezes colloid and moves downward, and promotes glue The discharge of body, meanwhile, up and down motion of the plectrum in pen container has stirred colloid, ensure that the mobility of colloid.

1 inner top of pen container is equipped with bearing 12, and the spring 3 is located at the axial centre of bearing 12, in the bearing 12 It is arranged with riffled tube 7, the riffled tube 7 is set on syringe needle 2, and the screw pitch of the riffled tube 7 is 7-8mm, described interior The outer wall of screwed pipe 7 is equipped with several stirring blades 70.In this way, driving riffled tube to move downward, due to interior spiral shell after pen container pushes The screw pitch of line pipe is larger, has reached 7-8mm, so, syringe needle shore effect under, riffled tube starts to rotate, in bearing block Support under, the spinning movement of riffled tube is more smooth, and opposite pen container will not generate displacement；It is set on the outer wall of riffled tube There is stirring blade, stirring blade is rotated with the rotation of riffled tube, in this way, being flipped the colloid in pen container, really The mobility of colloid is protected.

The syringe needle 2 is equipped with sliding block 22, and the inner wall of the pen container 1 is equipped with axial sliding slot 13, and the sliding block 22 is adapted to It is slided in sliding slot 12 on ground.The cooperation of sliding block and sliding slot, so that radial displacement will not occur for syringe needle, it is ensured that syringe needle is reliably shored Riffled tube；Sliding block is greater than shift length of the syringe needle lower part with respect to pen container with respect to the distance of riffled tube, that is to say, that syringe needle phase After rising to highest point to pen container, sliding block will not touch the bottom of riffled tube, it is ensured that sliding block will not stop the axial fortune of syringe needle It is dynamic.

2 lower end of syringe needle is in arc-shaped, and 2 surface of syringe needle is equipped with polytetrafluorethylecoatings coatings.End is in circular arc Shape plays positioning action, meanwhile, increase and operates reliable with the contact area to dispensing frame, raising dispensing；Polytetrafluoroethylene (PTFE) tool There are high sliding property and non-sticky property, it can be ensured that colloid syringe needle of postponing equably flows downwards, improves the reliability of dispensing operation.
