Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a mouse is small-size hemostatic forceps for experiments, including tong bar 1 and forceps holder 4, the equal fixed welding in 1 left side both ends of tong bar has the connecting block, all rotate on two sets of connecting blocks and install a set of forceps holder 4, two sets of forceps holder 4 are close to the equal coaxial gear 5 that is fixed with of one end of tong bar 1, the activity chamber has been seted up to tong bar 1 inside, a plurality of constant head tanks 6 that are linear distribution have all been seted up to the both sides in activity chamber, movable intracavity slidable mounting has telescopic link 2, telescopic link 2 is multistage through the joint subassembly to be fixed in the activity intracavity, the left side fixed connection rack 3 of telescopic link 2, the one end that telescopic link 2 was kept away from to rack 3 runs through the left side of tong bar 1 and is connected with the meshing of gear 5. Through promoting telescopic link 2 for telescopic link 2 drives rack 3 and acts on gear 5 to this drives tong 4 and carries out the synchronous action that opens and shuts, thereby has omitted the action that opens and shuts of 1 part of tong pole, has reduced the misery of mouse, has reduced experimenter's the operation degree of difficulty.

As shown in fig. 1 and 2, a through groove is formed in the telescopic rod 2, a clamping assembly is arranged in the through groove and comprises two sets of moving blocks 7 and clamping blocks 8 which are in mirror symmetry, a first magnetic block 9 and a second magnetic block 10 are sequentially and fixedly arranged on one side, close to each other, of the two sets of moving blocks 7, the first magnetic block 9 and the second magnetic block 10 are arranged in a manner that like magnetic poles are opposite, one end of each clamping block 8 is fixedly connected with the corresponding moving block 7, and the other end of each clamping block 8 is inserted into the corresponding positioning groove 6. Utilize repulsion between first magnetic path 9 and the second magnetic path 10 to act on movable block 7 for movable block 7 atress drives the fixture block and inserts and establish in constant head tank 6, thereby carries out spacing fixed to telescopic link 2 fast, and cooperatees with the joint subassembly through selective use constant head tank 6, can play multistage regulation and fixed effect to telescopic link 2.

As shown in fig. 2, the upper end face of the telescopic rod 2 is provided with a slot, an inverted T-shaped stop block 13 is slidably mounted in the slot, a bottom fixed connection S-shaped elastic sheet 14 of the inverted T-shaped stop block 13 is provided, two ends of the S-shaped elastic sheet 14 are provided with a set of pressing plates 12, the upper end face of the moving block 7 is provided with a slope cavity, one end of each pressing plate 12 is fixedly connected with the inverted T-shaped stop block 13, and the other end of each pressing plate 12 is inserted into the slope cavity and is in sliding contact with the slope cavity. By pressing the stop block 13, the stop block 13 extrudes the S-shaped elastic sheet 14 and drives the pressing plate 12 to move downwards and act on the inclined cavity, so that the moving block 7 is stressed and is drawn out from the positioning groove 6, and the telescopic rod 2 can normally slide at the moment.

As shown in fig. 2, the telescopic rod 2 is an inverted T-shaped structure, a plurality of universal balls 11 distributed in a rectangular array are fixedly arranged at the bottom of the telescopic rod 2, two sets of sliding grooves are formed in the bottom of the movable cavity, and the universal balls 11 are in rolling fit with the sliding grooves. By using the universal ball 11 as the support of the telescopic rod 2 to contact with the movable cavity, the contact area is small, and the friction resistance is small.

The working principle is as follows: in practical use, firstly, the stopper 13 is pressed to extrude the S-shaped elastic sheet 14 and drive the pressing plate 12 to move downwards and act on the inclined surface cavity, so that the moving block 7 is stressed and is pulled out from the positioning groove 6, and at this time, the telescopic rod 2 can normally slide. Then, the telescopic rod 2 is moved to the left side, so that the rack 3 acts on the straight gear 5, and the straight gear 5 drives the two groups of forceps clamps 4 to be opened towards two sides; when the telescopic rod 2 moves towards the right side, the rack 3 acts on the straight gear 5, so that the straight gear 5 drives the two groups of forceps jaws 4 to be closed inwards, and the effect of stopping bleeding is achieved; and utilize the repulsion between first magnetic path 9 and the second magnetic path 10 to act on movable block 7 for movable block 7 atress drives the fixture block and inserts and establish in constant head tank 6, thereby carries out spacing fixed to telescopic link 2 fast, and cooperatees with the joint subassembly through selective use constant head tank 6, can play multistage regulation and fixed effect to telescopic link 2.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
