Abstract

The utility model discloses a kind of novel glass head minute hands, it is characterized in that, including L shape needle handle, two ends of the needle handle are removably equipped with glass syringe needle correspondingly, one end of the separate needle point of the glass syringe needle can be in the handle pipe of needle handle end described in partial insertion, and is screwed residence and states glass syringe needle.A kind of novel glass head minute hand that the embodiments of the present invention provide, structure is simple, syringe needle and needle handle be separable, syringe needle and the production of needle handle unlike material, the blunt all interconvertible glass head minute hand of syringe needle size point, effect identical with glass minute hand can be played, it is again durable simultaneously, it is hardly damaged, reduces waste.The experimental facilities, production is simple, at low cost, easy to operate, has the characteristics that economic, practical, feasible.

Description

A kind of novel glass head minute hand

Technical field

The utility model relates to technical field of experiment equipment, and in particular to a kind of novel glass head minute hand.

Background technique

In Creativity in Experimental Teaching of Animal Physiology, preparation of specimen is carried out through common frog, toad, bullfrog or other animals etc., was made It needs to use glass minute hand in journey.Glass minute hand is smooth, and needle point position point is sliding, these be all conducive to tissue required for separating or Organ is widely adopted without sample required for damaging.But glass minute hand also has the shortcomings that fatal, is exactly easy to damage. The needle point of glass minute hand is impaired, and the glass minute hand of other positions carefully cannot use or the handle of glass minute hand is disconnected, The glass minute hand of its position carefully cannot also use.Especially when first used, spoilage is very high by student, causes very big Waste.

Fig. 1 is the glass minute hand 10 under the prior art, including glass minute hand handle 11 and glass minute hand syringe needle 12.

Utility model content

To solve the above-mentioned problems in the prior art, the utility model provides a kind of novel glass head minute hand, wraps Include L shape needle handle, two ends of the needle handle are removably equipped with glass syringe needle correspondingly, the glass syringe needle it is separate One end of needle point can be in the handle pipe of needle handle end described in partial insertion, and is screwed residence and states glass syringe needle.

Preferably, the needle handle is made of the metal of smooth duroplasts or lightweight.

Preferably, the glass syringe needle is articulated with the needle handle end point, in use, the glass syringe needle is located at shown needle The outside of pommel head；When not in use, the glass syringe needle is hidden in the inside of the needle handle end.

The utility model has the advantages that

A kind of novel glass head minute hand that the embodiments of the present invention provide, structure is simple, syringe needle and needle handle be separable, Syringe needle and the production of needle handle unlike material, the blunt all interconvertible glass head minute hand of syringe needle size point, can play and glass minute hand phase Same effect, at the same it is again durable, it is hardly damaged, reduces waste.The experimental facilities, production is simple, at low cost, easy to operate, tool Have the characteristics that economic, practical, feasible.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of novel glass head minute hand under the prior art；

Fig. 2 is a kind of structure schematic diagram of novel glass head minute hand of the utility model embodiment.

Wherein: the glass minute hand under the 10- prior art；Needle handle under the 11- prior art；Syringe needle under the 12- prior art； 20- needle handle；202- glass needle is first；204- glass syringe needle two；201- screw one；203- screw two.

Specific embodiment

Technical solutions of the utility model are discussed in detail with reference to the accompanying drawing.

As shown in Fig. 2, the embodiments of the present invention disclose a kind of novel glass head minute hand, including L shape needle handle, it is described Two ends of needle handle are removably equipped with glass syringe needle (glass needle first 202 and glass syringe needle 2 204) correspondingly, institute The one end for stating the separate needle point of glass syringe needle can be in the handle pipe of needle handle end described in partial insertion, and passes through screw (screw 1 Glass syringe needle 203) is secured the above with screw 2.

Further, the needle handle is made of the metal (the harder metal of lightweight) of smooth duroplasts or lightweight.Tool Body, the syringe needle of glass head minute hand is made of glass, and there are circular pipe gap or the screw hole of back cover in the inside of syringe needle bottom, just In fixed glass syringe needle (glass needle first 202 and glass syringe needle 2 204) with screw (screw 1 and screw 2 203).It is existing Glass minute hand under technology, syringe needle, needle handle integration, is all made of glass.

Further, the glass syringe needle is articulated with needle handle end point (not shown), in use, the glass syringe needle Positioned at the outside of shown needle handle end；When not in use, the glass syringe needle is hidden in the inside of the needle handle end.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.

Claims

1. a kind of novel glass head minute hand, which is characterized in that including L shape needle handle, two ends of the needle handle are correspondingly Removably be equipped with glass syringe needle, one end of the separate needle point of the glass syringe needle can needle handle end described in partial insertion handle pipe It is interior, and be screwed residence and state glass syringe needle.

2. novel glass head minute hand according to claim 1, which is characterized in that the needle handle using smooth duroplasts or The metal of lightweight is made.

3. novel glass head minute hand according to claim 1, which is characterized in that the glass syringe needle is articulated with the needle handle End point, in use, the glass syringe needle is located at the outside of shown needle handle end；When not in use, the glass syringe needle is hidden in institute State the inside of needle handle end.
