Description

Technical Field

[0001] This application relates to the technical field of sewing and removing thread ends, and in particular to a sewing and thread-removing device for musical instrument bags. Background Technology

[0002] Thread ends typically refer to the exposed end of a cable (such as wires, cables, optical fibers, textile threads, etc.) or the excess portion that needs to be processed during manufacturing.

[0003] However, in practical applications, most existing sewing thread ends are usually cut off directly with scissors. However, scissors are operated by using the knuckles, which can cause discomfort in the knuckles after prolonged use, hindering their widespread adoption.

[0004] Therefore, those skilled in the art have provided a device for sewing and removing loose threads from musical instrument bags to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issue raised in the background art that scissors require forceful operation using the knuckles, which can cause discomfort after prolonged use and hinder widespread adoption, this application provides a device for removing thread ends when sewing instrument cases.

[0006] The instrument bag sewing and thread removal device provided in this application adopts the following technical solution: it includes a connecting ring, and two transmission frames are rotatably connected to the outer side of the connecting ring. Each of the two transmission frames has a concave hole on its opposite side, and a triangular blade is fixedly connected to each of the two transmission frames on its opposite side. The two triangular blades are symmetrically staggered.

[0007] Preferably, the inner walls of the two recesses are fixedly connected to the same arc-shaped elastic sheet.

[0008] Preferably, limit rings are fixedly connected to the outer sides of both transmission frames, and a U-shaped handle is fixedly connected to the top side of one of the transmission frames.

[0009] Preferably, both of the transmission frames have locking holes on their outer sides, and the same U-shaped bolt is inserted into the inner wall of both locking holes.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. By setting triangular blades, manually grasp the transmission frame to adjust its position. When the two triangular blades are moved to both sides of the thread end that needs to be cut, squeeze the two transmission frames together. At this time, the thread end can be cut with the two triangular blades. This method can avoid contact with the hand joints during the process of cutting the thread end, thereby avoiding discomfort and facilitating its widespread use.

[0012] 2. By setting an arc-shaped elastic sheet, when two transmission frames pinch each other and approach, the rebound force of the arc-shaped elastic sheet can be used to facilitate the rebound of the two transmission frames that are close together, so as to repeat the shearing operation.

[0017] The following will be combined with the appendix Figure 1-3 The technical solution of this utility model has been clearly and completely described. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] This application discloses a device for sewing and removing loose threads from a musical instrument bag, referring to... Figure 1-3 The device includes a connecting ring 1, with two transmission frames 2 rotatably connected to the outer side of the connecting ring 1. Each transmission frame 2 has a recessed hole on its opposite side, and a triangular blade 4 is fixedly connected to each of the opposite sides of the transmission frames 2. The two triangular blades 4 are symmetrically staggered. By setting the triangular blades 4, the transmission frames 2 can be manually grasped and moved to adjust their position. When the two triangular blades 4 are moved to both sides of the thread end that needs to be cut, the two transmission frames 2 are squeezed together and brought closer. At this time, the thread end can be cut using the two triangular blades 4. This method avoids contact with the hand joints during the thread cutting process, thus avoiding discomfort and facilitating its widespread use.

[0019] In this application, the inner walls of the two concave holes are fixedly connected to the same arc-shaped elastic sheet 3; by setting the arc-shaped elastic sheet 3, when the two transmission frames 2 pinch each other and move closer, the rebound force of the arc-shaped elastic sheet 3 can be used to facilitate the two transmission frames 2 moving closer together to rebound, so as to facilitate repeated cutting operations.

[0020] In this application, limit rings 5 ​​are fixedly connected to the outer sides of both transmission frames 2, and a U-shaped handle 6 is fixedly connected to the top side of one of the transmission frames 2. By setting the limit rings 5 ​​and the U-shaped handle 6, when controlling the transmission frame 2, the thumb and index finger can be placed between the two limit rings 5 ​​respectively, thereby preventing the hand from slipping during operation. At the same time, the other three fingers can be used to grip the U-shaped handle 6, ensuring the stability of the overall operation and the synchronization between the control and the hand.

[0021] In this application, both transmission frames 2 have locking holes 7 on their outer sides, and the same U-shaped plug 8 is inserted into the inner wall of the two locking holes 7. By setting the locking holes 7 and the U-shaped plug 8, when not in use, the two triangular blades 4 are brought close to each other and made to contact each other in a staggered manner, and then the U-shaped plug 8 is inserted into the two locking holes 7 at the same time. At this time, the blade edge of the triangular blades 4 can be covered to avoid accidents.

[0022] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0023] The implementation principle of the instrument bag sewing and thread removal device in this application embodiment is as follows: During use, the transmission frame 2 is manually grasped and moved to adjust its position. Once the two triangular blades 4 are moved to the sides of the thread to be cut, the two transmission frames 2 are pinched together. At this point, the thread can be cut using the two triangular blades 4. This method avoids contact with the hand joints during thread cutting, thus preventing discomfort and facilitating widespread use. When the two transmission frames 2 are pinched together and brought closer, the rebound force of the arc-shaped elastic sheet 3 facilitates the movement of the two blades. The transmission frame 2 springs back to facilitate repeated cutting operations. When controlling the transmission frame 2, the thumb and forefinger can be placed between the two limit rings 5 ​​to prevent slippage during operation. At the same time, the other three fingers can be used to grip the U-shaped handle 6 to ensure the stability of the overall operation and the synchronization between the control and the hand. When not in use, the two triangular blades 4 are brought close together and made to staggered contact. Then, the U-shaped bolt 8 is inserted into the two locking holes 7 at the same time. At this time, the blade edge of the triangular blade 4 can be covered to avoid accidents.

[0024] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
