Description
Technical field
This utility model relates to a kind of device of testing for the outstanding tail of Mus in Animal Behavior Science experiment.Outstanding tail experiment is the experimental technique of whether suffering from depression for identification experiment Mus, is difficult point but how experimental mouse suspension is sling in experiment always.This tail suspension device can easily be clamped the tail of experimental mouse to sling and unclamp taking-up, belongs to zoopery instrument.
Background technology
Experimental mouse is hanged tail experimental check its while whether suffering from depression, tail suspension need to be observed for six minutes, in suspention process, mouse does not do violent struggle and quieter person is inclined to for depression, otherwise is inclined to without depression.The method of existing tail suspension is mainly to use rope ligation or typical clamp directly to suspend Mus tail in midair.But because Mus tail is pyramid type, root is thick, and end is thin, when suspention, suspension rope need to be fixed on to the end of Mus tail.In the time that the body weight of Mus is larger, use rope ligation or directly suspend Mus tail in midair by typical clamp very easily to come off.If rope ligation tension, or clip excessively clamps, and can cause: Mus tail skin avulsion injuries, Mus tail from disconnected, Mus tail ischemic necrosis, can not proceed experiment.In addition also can be interfered because the pain of Mus tail causes experimental result.In the time of large batch of zoopery, existing with the fixing Mus tail of rope ligating methods, not only consuming time many, and inefficiency.While using typical clamp, bearing and Mus tail contact area are little, very easily cause the damage of Mus tail.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned weak point of the prior art, design a kind of can Fast Installation and dismounting, the fixation tail suspension device without can not coming off in wound, suspention process, to the glitch-free experimental mouse of experimental result.
The tail suspension device of experimental mouse of the present utility model, comprise suspension rope and Mus tail holder, it is characterized in that Mus tail holder comprises inner sleeve, outer sleeve, Compress Spring, conical head, described outer sleeve upper end is provided with liner ring, and inner sleeve middle part is provided with step, and inner sleeve bottom is provided with arc spring leaf pawl, outer sleeve is sleeved on inner sleeve, Compress Spring is contained between liner ring and step, and conical head is enclosed within on arc spring leaf pawl and is arranged on outer sleeve bottom, and outer sleeve is connected with suspension rope.
For the ease of regulating the bore that tightens up mouth of arc spring leaf pawl composition and tightening up pressure, described outer sleeve bottom is provided with female thread, conical head is provided with external screw thread, conical head is contained in through external thread rotary on the female thread of outer sleeve, regulate the conical head position of lower cartridge outside, i.e. the bore tightening up mouthful of scalable arc spring leaf pawl composition and tighten up pressure.
For in being convenient to clamp mouse tail, the quantity of described arc spring leaf pawl is selected 2～4, is preferably 3.
Bad in order to prevent that mouse tail from being pressed from both sides, can on the arcwall face of the front end inner side of arc spring leaf pawl, be pasted with flexible protective layer, as rubber or felt etc.
The tail suspension device of experimental mouse of the present utility model, there is reasonable in design, simple to operation, work efficiency is high,, can not come off in suspention process without wound to the fixation of Mus tail, the bore tightening up mouthful and tighten up the pressure advantage such as adjustable continuously, both be applicable to suspention rat and used, and be also applicable to suspention mice and use.

Fig. 1 is a kind of structural representation of the present utility model.
In Fig. 11 is hanging ring, the 2nd, hang handle, and the 3rd, inner sleeve, the 4th, liner ring, the 5th, Compress Spring; the 6th, step, the 7th, outer sleeve, the 8th, elastic force seam, the 9th, arc spring leaf pawl, the 10th, female thread; the 11st, external screw thread, the 12nd, conical head, the 13rd, flexible protective layer, the 14th, tighten up mouth.
Detailed description of the invention
Referring to accompanying drawing 1, the tail suspension device of experimental mouse of the present utility model, comprise suspension rope and Mus tail holder, it is characterized in that Mus tail holder comprises inner sleeve 3, outer sleeve 7, Compress Spring 5, conical head 12, described outer sleeve 7 upper ends are provided with liner ring 4, inner sleeve 3 middle parts are provided with step 6, inner sleeve bottom is provided with arc spring leaf pawl 9, outer sleeve 7 is sleeved on inner sleeve 3, Compress Spring 5 is contained between liner ring 4 and step 6, conical head 12 is enclosed within on arc spring leaf pawl and is arranged on outer sleeve 7 bottoms, and outer sleeve 7 is connected with suspension rope with hanging ring 1 through hanging handle 2.
For the ease of the pressure that tightens up that tightens up mouth 14 that regulates arc spring leaf pawl 9 to form, described outer sleeve 7 bottoms are provided with female thread 10, conical head 12 is provided with external screw thread 11, conical head 12 is through external screw thread 11 spinnings on the female thread 10 at outer sleeve 7, regulate conical head 12 in the position of outer sleeve 7 bottoms, i.e. the pressure that tightens up that tightens up mouth 14 of scalable arc spring leaf pawl composition.
For in being convenient to clamp mouse tail, the quantity of described arc spring leaf pawl 9 is selected 2～4, is preferably 3, is provided with elastic force seam 8 between arc spring leaf pawl 9.
Bad in order to prevent that mouse tail from being pressed from both sides, can on the arcwall face of the front end inner side of arc spring leaf pawl 9, be pasted with flexible protective layer 13, as rubber or felt etc.
When use, inner sleeve 3 is upwards mentioned with hands, the mouth 14 that tightens up of arc spring leaf pawl 9 lower ends is opened, again Mus tail is entered inner sleeve 3 from the muzzle that tightens up of arc spring leaf pawl lower end, unclamp inner sleeve, because of the elastic force of Compress Spring 5, inner sleeve 3 is stretched out downwards, arc spring leaf pawl 9 makes to tighten up mouth 14 and diminishes and clamp Mus tail under the effect of conical head 12, again due to the own wt of mouse, make arc spring leaf pawl have the trend moving down and further tighten up, having advantages of that fixation can not come off without wound with in suspention process.Due to the elasticity of arc spring leaf pawl 9 and the effect of flexible protective layer 13, can well prevent that mouse tail from being pressed from both sides bad.When experiment finishes, upwards lift again inner sleeve 3, can unclamp arc spring leaf pawl and easily Mus tail be taken out, also there is simple to operation and work efficiency advantages of higher, also can regulate the position of lower cartridge outside by conical head 12 spinnings owing to tightening up the bore of mouth 14 and tightening up pressure again, so, be both applicable to suspention rat and used, be also applicable to suspention mice and use.
