Abstract

The utility model relates to a clam dissecting device, comprising a knife holder plate, a dissecting knife which is hinged on the knife holder plate, a limiting baffle which is arranged at the left side of the dissecting knife in parallel and a clam body clamping member which is connected with the knife body of the dissecting knife. The clam body clamping member is composed of a fixing rod which is connected with the knife back with one end, a clam body clamp like the Chinese character 'ren' which is sheathed on the fixing rod and is spanned pressed on the knife back, a compression spring which is sheathed on the fixing rod and presses the clam body clamp and a compression spring closing ring. The knife holder plate and the limiting baffle which are corresponding to the cutting edge of the near middle part of the dissecting knife are provided with an open pore or a pit, and the shape is analogical with the section of the clam body. The utility model is used to locate the clam conveniently and make the edge of the dissecting knife cutting edge automatically align the opening of the clam body. The clam dissecting device has the advantages of artful design, simple structure, easy use, labor saving, time saving and safety.

Description

Cut open the freshwater mussel device

Technical field

The utility model belongs to shellfish housing opening device, specifically a kind of freshwater mussel device that cuts open.

Background technology

Utilize pond on a hill, reservoir to support and plant the important source of finance that pearl is China many local peasants in south, the cultivation mechanism of pearl is that the foreign matter for preparing is implanted in the nacreous body, because the stimulation of external foreign matter makes the freshwater mussel body secrete nacre foreign matter is coated up layer by layer, this time needs several years, treat it to be taken out in the freshwater mussel body after pearl cuts one's eye-teeth at leisure, traditional way is to insert from the opening and closing place of freshwater mussel cuing open cutter earlier, and then two tendons of freshwater mussel are cut off in the rotary-cut of taking advantage of a situation.Can shrink immediately two clam shells are clamped foreign matters because the pearl freshwater mussel is met foreign matter, so that two tendons that freshwater mussel is cut off in rotary-cut will with the hands pin the freshwater mussel body, the speed of so not only requiring great effort is also very slow, and the slow slightly even point of a knife of action sometimes inserts all difficult.

The utility model content

The purpose of this utility model be to provide a kind of fast, the labour-saving cuts open the freshwater mussel device.

The utility model is implemented by following technical proposals:

Of the present utility model cut open its profile of freshwater mussel device close with chopper by knife rest plate, be hinged on cuing open cutter, be set in parallel in the postive stop baffle that cuts open cutter left side, be connected that the freshwater mussel body fastener that cuts open on the cutter blade formed on the knife rest plate, postive stop baffle with cut open cutter and be arranged in parallel; Freshwater mussel body fastener then is the fixed bar that is connected with the knife back by an end, be set in to be attached to the freshwater mussel body card that cuts open place, cutter 2 left sides on the fixed bar and to be sleeved on stage clip and the stage clip back-up ring of pushing down freshwater mussel body card on the fixed bar and constituted, and it is used to limit swinging of freshwater mussel; And with the corresponding knife rest plate of cutting edge that cuts open the nearly middle part of cutter on be provided with perforate or pit with freshwater mussel body section similar shape; And also be provided with the pit that is complementary with the freshwater mussel body profile and be same as moving of restriction freshwater mussel towards cuing open this side of cutter with perforate on the knife rest plate or pit at postive stop baffle; The described cutter that cuts open also is provided with the return member, and this return member comprises that extension spring and branch are located at and cut open cutter and knife rest plate upper hinge, the two ends of extension spring respectively with cut open cutter, knife rest plate on articulated elements link to each other.

The freshwater mussel device that cuts open of the present utility model is provided with on knife rest plate and postive stop baffle and akin pit of clam shell shape or shrinkage pool, can easily freshwater mussel be located, more unique is to be provided with freshwater mussel body fastener can allow the blade cutting edge automatically aim at freshwater mussel body opening on the knife back, to cut open cutter and reset and added the return member in order to allow, its exquisite composition, simple in structure, easy to use, laborsaving, save time, safe and reliable.

Below in conjunction with accompanying drawing the utility model is further described

The specific embodiment

As shown in Fig. 1 to Fig. 3, the profile of cuing open the freshwater mussel device of the present utility model close with chopper by knife rest plate 1, be hinged on cuing open cutter 2, be set in parallel in the postive stop baffle 3 that cuts open cutter 2 left sides, be connected that the freshwater mussel body fastener 4 that cuts open on cutter 1 blade formed on the knife rest plate 1, postive stop baffle 3 with cut open cutter 2 and be arranged in parallel; 4 of freshwater mussel body fasteners be by an end with cut open fixed bar 41 that cutter 2 knife back are connected, be set in to be attached to the freshwater mussel body card 42 that cuts open place, cutter 2 left sides on the fixed bar and to be sleeved on stage clip 43 and the stage clip back-up ring 44 of pushing down freshwater mussel body card 42 on the fixed bar 41 and constituted, it is used to limit swinging of freshwater mussel; And with the corresponding knife rest plate 1 of cutting edge that cuts open the nearly middle part of cutter 2 on be provided with perforate or pit 11 with freshwater mussel body section similar shape; And also be provided with the pit 21 that is complementary with the freshwater mussel body profile and be used to limit moving of freshwater mussel equally towards cuing open cutter 2 these sides with perforate on the knife rest plate or pit 11 at postive stop baffle 3; The described cutter 2 that cuts open also is provided with return member 5, this return member 5 comprises that extension spring 51 and branch are located at and cuts open cutter 2 and knife rest plate 1

upper hinge

52,53, the two ends of extension spring 51 respectively with cut open cutter 2, knife rest plate 1 on articulated

elements

52,53 link to each other, from figure, it can also be seen that to be provided with and cut open cutter grab 6 in postive stop baffle 4 ends of cuing open cutter 2 these ends of handle of a knife.

During use, unplug and cut open cutter grab 6 and will cut open on the cutter 2 and carry, cut open cutter 2 because of the pulling force effect of return member 5 and can stagnate skyborne correct position this moment, again the pearl freshwater mussel hole of maturation is placed the perforate or the pit 11 of the freshwater mussel body section similar shape on the knife rest plate 1 up, the left side housing of freshwater mussel then is arranged in postive stop baffle 3 just towards the pit 21 that is complementary with the freshwater mussel body profile that cuts open that cutter 2 these sides are provided with, to cut open cutter 2 then and press down cutting-out, form between freshwater mussel body card 42 and the postive stop baffle 4 wedge shape at this moment the freshwater mussel body just seized on both sides by the arms between, and because the effect on inclined-plane and automatically keep the hole of freshwater mussel to aim at blade, again because of wide if will just must need to grow the cutter that cuts open cutter 2 to the card base length of the effective spacing then freshwater mussel body fastener 4 of freshwater mussel body, the card base of freshwater mussel body fastener 4 also will inevitably contact on the knife rest plate 1 prior to cuing open cutter 2 like this, because freshwater mussel body card is that movable set is on fixed bar 41, by knife rest plate 1 withstand the back just with the relative slip of fixed bar 41 generations, cut open that cutter 2 cutting edges move down and the card base of freshwater mussel body fastener 4 is motionless thereby make.

Certainly the utility model can also have other version, and present embodiment can not limit its invention.
