Description

Technical Field

[0001] This utility model relates to a positioning structure for garden shears, and more particularly to a positioning structure for preventing loosening of garden shear shaft bolts. Background Technology

[0002] Currently available garden shears include many such Figures 8 to 10 As shown, the garden shears 50 are formed by overlapping a first handle 52 with a blade plate 51 at one end and a second handle 54 with an anvil 53 at one end. A bolt 55 is installed at the overlap and then secured to the end of the bolt 55 with a nut 56. This allows the first handle 52 and the second handle 54 to be smoothly connected by the bolt 55. A fastener 57 is provided between the nut 56 and the anvil 53. The fastener 57 provides a latch for a stop 58, so that the garden shears 50 can be kept in the folded state when not in use. A gear 59 is provided on the fastener 57. The gear 59 is secured to one side of the anvil 5 by a screw. The nut 56 is also provided with an annular toothed edge 561. The annular toothed edge 561 engages with the gear 59 to prevent the nut 56 and the bolt 55 from loosening during the cutting operation of the garden shears 50.

[0003] However, the existing structure described above still has the following problems in practical applications: (i) the garden shears 50 need to be equipped with the gear 59 to achieve the anti-loosening positioning effect, so the overall components are numerous and complex; (ii) the garden shears 50 need to be equipped with the gear 59 to achieve the anti-loosening positioning effect, which makes the assembly of the garden shears 50 more complicated, which is also the main reason why the production cost of the garden shears 50 has not been reduced.

[0004] Therefore, how to develop and improve the existing garden shears to address their shortcomings is a goal that the relevant industry needs to strive for. In view of this, the applicant came up with the idea of ​​this utility model, and then designed it based on many years of experience. After extensive discussions, sample testing, and multiple revisions and improvements, this utility model was finally launched. Utility Model Content

[0005] The technical issues to be addressed:

[0006] Existing garden shears require the addition of gears to achieve a secure, non-loosening positioning effect; this is the technical problem we want to solve.

[0007] Technical characteristics of the problem-solving process:

[0008] This utility model provides a garden shears shaft bolt anti-loosening positioning structure, comprising: a garden shears body, a safety device, a shaft bolt, a nut, and at least one connecting unit. The garden shears body has a first handle, a second handle, a stop plate, a first cutting element, and a second cutting element. The first handle is fitted with the stop plate, which extends to provide support for the first cutting element. A slot is provided on one side surface of the second handle, and the second cutting element has a plug-in section inserted into the slot. The slot and the plug-in section are respectively positioned at their respective points. There is at least one first through hole and at least one second through hole. The end of the first through hole is further penetrated through the other side surface of the second grip via an enlarged corner hole. A non-circular fixing hole is penetrated through the abutment plate, and a through shaft is provided. The first shearing member and the second shearing member are respectively provided with a first pivot hole and a second pivot hole, and the first shearing member is provided with a through hole. The safety device has a stop buckle and a buckle plate. The stop buckle is installed on one side surface of the first grip. The buckle plate is provided with a third pivot hole and a third through hole. When the first shearing member and the second shearing member... When the cut piece and the fastener are stacked sequentially, and the through hole of the first cut piece provides the through shaft of the abutment for insertion, the third pivot hole is simultaneously aligned with the second pivot hole, the first pivot hole, and the fixing hole. The third through hole is aligned with the second through hole and the first through hole. The bolt has a bolt rod, one end of which is connected to an enlarged limiting head, and the other end extends out to a locking post. The bolt rod has a positioning cut surface on its outer periphery. When the bolt is continuously inserted through the third pivot hole, the second pivot hole, the first pivot hole, and the fixing hole with the bolt rod in place, the bolt is inserted into the bolt rod. In this design, the locking post protrudes to provide a locking mechanism for the nut. The positioning surface and the fixing hole act as a locking element to prevent the bolt from loosening. The connecting unit includes a T-shaped nut and a bolt. The T-shaped nut has a polygonal nut body and a threaded tube. The threaded tube is continuously inserted into the first through hole, the second through hole, and the third through hole. The bolt then locks the threaded tube, ensuring the nut body is fully secured in the corner hole. Therefore, a garden shear bolt anti-loosening positioning structure is obtained.

[0009] Compared to existing technologies, the following benefits are achieved:

[0010] This utility model provides a bobbin anti-loosening positioning structure for garden shears. The bobbin and the nut do not need to be installed with gears to ensure anti-loosening, which simplifies the complexity of the overall structure and makes assembly relatively easy and less cumbersome. As a result, the production cost of the garden shears of this utility model can be greatly reduced, giving it a greater competitive advantage in the same industry. Attached Figure Description
