Fig. 2 is a structural front view of the present utility model.

Fig. 3 is a fixed fastener structural front view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

Provide by Fig. 1-Fig. 3, this utility model comprises that two leaf butterfly types grab part, axostylus axostyle and axostylus axostyle spring, the butterfly type is grabbed part and is made of Handheld Division 2 and pecten portion, pecten portion is made of arc comb 5 and arc backboard 1, Handheld Division 2 links to each other with arc backboard 1, two leaf butterfly types are grabbed part and are linked together through axostylus axostyle 3, be set with on the axostylus axostyle 3 and fix the axostylus axostyle spring 4 that two leaf butterfly types are grabbed part, all be equipped with respectively on the two arc backboards and stretch to the staggered arc comb 5 of axostylus axostyle, the arc comb end has ballhead 6, back plate aperture 7 is arranged on the arc backboard 1, the arc backboard is equipped with adjustable extremity fixed fastener respectively by the side top and the bottom, and fixed fastener is by adjustable nut 8, double hook spring 10 and terminal threaded double hook 9 constitute.

In order to guarantee result of use, said fixed fastener has 4, is contained in two arc backboard upper and lowers respectively, is with the double hook spring on double hook 9 bodies of rod, connects adjustable nut on the double hook body of rod end, and double hook 9 is along axle center level 360 degree free adjustment; There is a side shield 11 on said two arc backboard tops near the fixed fastener inboard, and a side shield 11 has 2; Said arc comb 5 has a plurality of more than 4 at least, is encircling type and is fixed on the two arc backboards; Said back plate aperture 7 is elongated, has a plurality of more than 4 at least, all puts respectively on two arc backboards.

This utility model is plastics or the metal apparatus that grasps that is the butterfly type, wherein, the Handheld Division is experimenter's a portion of the handle, pecten portion is used to grasp and fixing muroid, pecten portion is divided into arc comb and arc backboard two parts again, arc comb is as grasping and the fixing fixed teeth of muroid body, fixing head after the arc backboard grasps as muroid, after grasping, muroid is fixed in the oblate space of arc comb and arc backboard formation, the terminal ballhead design of arc comb, when preventing that the experimenter from operating mouse is damaged, arc backboard side designs adjustable extremity fixed fastener up and down respectively, the fixed fastener fixing limbs is simple and efficient, and the double hook of fixed fastener can be along axle center level 360 degree free adjustment, and constant intensity can be regulated jointly by its adjustable nut that connects later and double hook spring, design back plate aperture on the arc backboard, increased the frictional force that grasps the back Mus back of the body and arc backboard, an arc backboard upper design side shield is used to grasp the fixing of back muroid head.This utility model makes two leaves grab the constant resilience grip of part generation nature by means of the axostylus axostyle spring that is wrapped on the axostylus axostyle, has overcome the randomness of hands grip, has reduced operation and has disturbed.

Operating position of the present utility model is, the hand-held two leaf butterfly types of experimenter are grabbed the Handheld Division of part, use thumb and all the other four fingers firmly to open the pecten portion that the butterfly type is grabbed part, then arc comb is aimed at the body trunk portion of muroid, make two leaves grab part to produce the constant resilience grip of nature and pick up mouse gently by means of being wrapped in axostylus axostyle spring on the axostylus axostyle, make its back be close to the arc backboard naturally, just can implement experimental implementation, fixing limbs if desired, can use hands or tweezers pull-up to hold double hook on the Mus device arc backboard and extremity are blocked be fixed in the double hook, then implementation and operation.This utility model time grasps evidence through hundreds of, and using this to hold the Mus device, that experimental rat is grasped fixing operation is consistent, safe, efficient, has reached in testing Mus to experimenter's zero injury rate target.This utility model is easy to use, and is simple in structure, and safety grasps effectively, and economy and social effect are remarkable.
