End is fixed with telescopic rod, and telescopic rod is fixed with magnifying glass far from rotating cylinder side, and needle body top is fixed with company through station top
Female connector, connector sleeve upper inner are socketed with the first arc block, are equipped with movable plate on the inside of the first arc block, movable plate is far from first
The side of arc block is equipped with the second arc block, and the second arc block upper inner is fixed with spring, socket on the outside of the second arc block
There is ring set, ring set upper inner is socketed with connecting column, and connection top end is fixed with screw rod block, is socketed with traveller outside screw rod block,
Traveller apical lateral is socketed with nut.
Preferably, internal screw thread is offered inside the traveller, offers external screw thread outside sliding block.
Preferably, the movable plate is two, and is connected by a hinge between movable plate middle part.
Preferably, the connector sleeve is funnel-shaped.
Preferably, the handle is two, and symmetric handles are distributed in station two sides.
Preferably, the needle body top offers aperture.
The utility model, structure is simple, can clearly and intuitively be seen by the cooperation of needle body high scale and magnifying glass
The depth of needle insertion out, while traveller and needle body junction use arc block, ensure that the needle body when pulling out traveller insertion seal wire
Position do not influenced and changed by external force, enhanced convenience, while nut and internal screw block be by the cooperation of internal and external threads can
With the depth of more accurate control needle insertion, the funnel-form of connector sleeve also makes insertion seal wire become to be more easier.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the utility model overall structure diagram;
Fig. 2 is structure enlargement diagram at A in the utility model Fig. 1;
Fig. 3 is structural profile illustration at B in the utility model Fig. 1.
Specific embodiment
1-3 is described in further details specific embodiment of the present utility model with reference to the accompanying drawing.
Embodiment one, is provided by Fig. 1, Fig. 2 and Fig. 3, and the utility model includes station 1, and 1 bottom end of station is equipped with sea
Silk floss 2 guarantees that work top is not contaminated, 1 bottom end of station is fixed with needle body 3, needle through sponge 2 convenient for control blood from overflowing
Scale 4 is offered on the outside of body 3, convenient for the depth of control needle insertion, 1 top two sides of station are welded with handle 5, and handle 5 is remote
Side from station is fixed with cursor 6, and 6 side of cursor is hinged with rotating cylinder 7, and 7 bottom end of rotating cylinder is fixed with telescopic rod 8, stretches
Contracting bar 8 is fixed with magnifying glass 9 far from 7 side of rotating cylinder, convenient for being more clear the depth for intuitively finding out needle insertion, 3 top of needle body
It is fixed with connector sleeve 10 through 1 top of station, 10 upper inner of connector sleeve is socketed with the first arc block 11, the first arc block 11
Inside is equipped with movable plate 13, and movable plate 13 is equipped with the second arc block 12, the second arc far from the side of the first arc block 11
12 upper inner of block is fixed with spring 14, and ring set 15 is socketed on the outside of the second arc block 12, easy to disassemble, to make to separate hour hands
Position itself is not influenced by external force, alleviate the work difficulty of doctor, 15 upper inner of ring set is socketed with connecting column 16, connecting column
16 tops are fixed with screw rod block 17, and traveller 21 is socketed with outside screw rod block 17, and 21 apical lateral of traveller is socketed with nut 20, is convenient for
The depth of more accurate control needle insertion.
Embodiment two offers internal screw thread 18, offers outside traveller 21 on the basis of example 1 inside traveller 21
External screw thread 19, in order to the depth for cooperating more accurate control needle body 3 to be inserted by internal and external threads.
Embodiment three, on the basis of example 1, movable plate 13 are two, and pass through hinge between 13 middle part of movable plate
