DETAILED DESCRIPTION

[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0031] A Pengze crucian carp broodstock oxytocin injection device, such as Figure 1 and Figure 2As shown, it includes a support base 1, a mounting frame 2, a threaded column 3, a first clamping nut 4, an adjustment mechanism 5 and a clamping mechanism 6. The right part of the support base 1 is rotatably connected to the threaded column 3, the front side of the threaded column 3 is threadedly connected to the first clamping nut 4, the threaded column 3 is connected to the mounting frame 2, the mounting frame 2 is provided with an adjustment mechanism 5, and the mounting frame 2 is provided with a clamping mechanism 6.

[0032] In order to improve the spawning efficiency of Pengze crucian carp broodstock, it is necessary to regularly inject oxytocin into the Pengze crucian carp broodstock. During the injection process, the present device can be used to assist the breeders in operating. First, according to the operating habits of the breeders, the first clamping nut 4 is controlled so that the threaded column 3 can be rotated, and then the angle of the mounting frame 2 is adjusted. Then, the Pengze crucian carp broodstock is clamped and limited by the clamping mechanism 6, and then the adjustment mechanism 5 is adjusted and used, and then the Pengze crucian carp broodstock can be injected with oxytocin through the adjustment mechanism 5.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism 5 includes a sliding seat 51, a rotating member 52, a rotating seat 53, a first sliding frame 54, a second sliding frame 55, a second clamping nut 56, a syringe 57, a third sliding frame 58 and a sliding baffle 59. The sliding seat 51 is slidably connected to the left side of the mounting frame 2, the rotating member 52 is rotatably connected to the sliding seat 51, the rotating seat 53 is rotatably connected to the right side of the rotating member 52, the first sliding frame 54 is slidably connected to the rotating seat 53, the second sliding frame 54 is slidably connected to the right side of the first sliding frame 54, the second clamping nut 56 is threadedly connected to the second sliding frame 55, the syringe 57 is clamped on the second sliding frame 55, the third sliding frame 58 is slidably connected to the rear side of the second sliding frame 55, and the sliding baffle 59 is slidably connected to the upper part of the third sliding frame 58.

[0034] When injecting oxytocin into Pengze crucian carp broodstock, according to the size and placement of the Pengze crucian carp broodstock, firstly slide the sliding seat 51, then rotate the rotating member 52 and the rotating seat 53, so that the position of the first sliding frame 54 is adjusted, then the second clamping nut 56 is rotated so that the second sliding frame 55 is no longer fixed, and then the position of the second sliding frame 55 is adjusted so that the syringe 57 can be above the Pengze crucian carp broodstock. After the position is confirmed, the first sliding frame 54 is pushed downward, so that the second sliding frame 55 moves downward, and the syringe 57 also moves downward and is inserted into the body of the Pengze crucian carp broodstock, and then the third sliding frame 58 is pushed downward, so that the sliding baffle 59 is against the injection The injector 57 is pushed to push the oxytocic agent into the body of the Pengze crucian carp broodstock to complete the oxytocic agent injection. After the injection is completed, the above-mentioned components can be reset by reverse operation. Finally, the sliding baffle 59 is pushed backward so that the injector 57 is no longer blocked. Then the injector 57 is taken out from the second sliding frame 55, and the oxytocic agent is replenished. In summary, by adjusting the sliding seat 51, the rotating member 52 and the rotating seat 53, the injection angle of the injector 57 is preliminarily adjusted, and then the position of the second sliding frame 55 is adjusted, and then the injection position of the injector 57 is adjusted, that is, by continuously adjusting the position of the injector 57, the injector 57 can achieve the effect of multi-angle and multi-position adaptive injection.

[0035] like Figure 1 and Figure 5 As shown, the clamping mechanism 6 includes a first lifting frame 61, a first spring 62, a lifting rod 63, a clamping plate 64, a second spring 65, a first fixing member 66, a first clamping block 67 and a third spring 68. The left part of the installation frame 2 is slidably connected with the first lifting frame 61, the first spring 62 is connected between the first lifting frame 61 and the installation frame 2, the first spring 62 is wound on the first lifting frame 61, the right part of the first lifting frame 61 is slidably connected with the lifting rod 63, the bottom of the lifting rod 63 is slidably connected with the clamping plate 64, the bottom of the clamping plate 64 is an arc structure, the second spring 65 is connected between the clamping plate 64 and the first lifting frame 61, the upper side of the right part of the installation frame 2 is connected with the first fixing member 66, the first clamping block 67 is slidably connected to the first fixing member 66, the rear part of the first clamping block 67 is an inclined structure, and the third spring 68 is connected between the first clamping block 67 and the first fixing member 66.

[0036] In order to facilitate the breeding personnel to inject oxytocin into the Pengze crucian carp broodstock, the Pengze crucian carp broodstock needs to be limited and fixed during the injection process to prevent the Pengze crucian carp broodstock from moving around. First, the pressing plate 64 needs to be slidably adjusted according to the position of the Pengze crucian carp broodstock, and then the first lifting frame 61 is pressed downward, so that the first spring 62 is compressed and the lifting rod 63 is driven to move downward. The lifting rod 63 drives the pressing plate 64 to move downward and clamps and fixes the Pengze crucian carp broodstock. At the same time, as the pressing plate 64 contacts the Pengze crucian carp broodstock and clamps it, the lifting rod 63 will start to slide upward, the second spring 65 is compressed, and the first lifting frame 61 slides downward to contact the first block 67 and push the first block 67, so that The first clamping block 67 slides forward, and the third spring 68 is compressed. As the first lifting frame 61 continues to slide downward, the first clamping block 67 is no longer squeezed. Under the action of the third spring 68, the first clamping block 67 will slide backward and reset, and limit and lock the first lifting frame 61 to prevent the first lifting frame 61 from sliding upward and resetting. At the same time, the clamping plate 64 also continues to maintain the clamping limit on the Pengze crucian carp broodstock. In summary, by pressing the first lifting frame 61 downward, the clamping plate 64 clamps and limits the Pengze crucian carp broodstock, thereby preventing the Pengze crucian carp broodstock from moving around and affecting the normal injection during the injection of the oxytocin. At the same time, the first lifting frame 61 is locked by the first clamping block 67, so that the clamping plate 64 can continue to maintain the clamping state.

[0037] like Figure 1 and Figure 6 As shown, an injection mechanism 7 is also included, and the injection mechanism 7 includes an electric push rod 71, a second lifting frame 72, a connecting frame 73 and a fourth spring 74. The top of the rotating seat 53 is connected to the electric push rod 71 by bolts, and the second lifting frame 72 is connected to the telescopic end of the electric push rod 71. The upper left side of the first sliding frame 54 is connected to the connecting frame 73 by bolts. The second lifting frame 72 is slidably connected to the connecting frame 73, and a fourth spring 74 is connected between the second lifting frame 72 and the connecting frame 73.

[0038] When it is necessary to inject oxytocin into the Pengze crucian carp broodstock, the electric push rod 71 can be directly started. The telescopic end of the electric push rod 71 drives the second lifting frame 72 to move, so that the second lifting frame 72 pushes the connecting frame 73, and then the first sliding frame 54 slides downward first, and then the second lifting frame 72 pushes the third sliding frame 58, and at the same time, the fourth spring 74 is compressed, thereby achieving the effect of automatically pushing the syringe 57 for injection. In summary, the electric push rod 71 drives the second lifting frame 72 to move, so that the first sliding frame 54 moves downward first, and then automatically pushes the third sliding frame 58 to slide downward, so that the syringe 57 automatically performs the injection operation.

[0039] like Figure 1 , Figure 7 and Figure 8 As shown, a blocking mechanism 8 is also included, and the blocking mechanism 8 includes a blocking plate 81, a fifth spring 82, a second fixing member 83, a second clamping block 84 and a sixth spring 85. The blocking plate 81 is slidably connected to the rear of the mounting frame 2, and the fifth spring 82 is connected between the blocking plate 81 and the mounting frame 2. The right portion of the mounting frame 2 is connected to the second fixing member 83, and the second clamping block 84 is slidably connected to the second fixing member 83. The rear portion of the second clamping block 84 is a slope structure, and the sixth spring 85 is connected between the second clamping block 84 and the second fixing member 83.

[0040] The blocking plate 81 is then moved back to the original position so that the second spring 82 is pressed against the locking plate 84 and the locking plate 85 is pressed against the locking plate 84.

[0041] like Figure 1 and Fig. 9 As shown, it also includes a pulling mechanism 9, which includes a fixed seat 91 and a pulling frame 92. The fixed seat 91 is connected to the right side of the installation frame 2, and the pulling frame 92 is slidably connected to the fixed seat 91.

[0042] When it is necessary to pull the first clamping block 67 and the second clamping block 84 so that the first lifting frame 61 and the blocking plate 81 are no longer limited and fixed, the pulling frame 92 can be directly pulled forward, so that the first clamping block 67 is pulled forward first, and then the first lifting frame 61 is no longer blocked. At this time, as the first lifting frame 61 is reset, the breeder can release the Pengze crucian carp broodstock after the injection, and then continue to pull the pulling frame 92, so that the second clamping block 84 is pulled forward. At this time, the blocking plate 81 is no longer blocked by the second clamping block 84, and the blocking plate 81 will be reset under the action of the fifth spring 82. In summary, by pulling the pulling frame 92, the first clamping block 67 and the second clamping block 84 are pulled in turn, so that the first lifting frame 61 and the blocking plate 81 can be automatically reset.

[0043] like Figure 1 and Fig.10As shown, it also includes a protection mechanism 10, which includes a rotating plate 101, a sliding ring 102 and a protection tube 103. The rotating plate 101 is rotatably connected to the front of the installation frame 2, the sliding ring 102 is slidably connected to the rotating plate 101, and the protection tube 103 is slidably connected to the sliding ring 102.

[0044] In order to prevent the needle of the syringe 57 from being damaged by collision in daily state, the protective tube 103 can effectively protect the needle of the syringe 57. When the syringe 57 needs to be used, first slide the protective tube 103 downward, then push the sliding ring 102 to the left, and finally rotate and raise the rotating plate 101.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
