Detailed Embodiment

[0023] To further understand the content of the present utility model, the present invention will be described in detail in combination with the appended Figures 1-5 drawings and embodiments.

[0024] Combined with the attached Figures 1-5 , an auxiliary needle for a quilt fastener in this embodiment includes a handle body 1, a hook needle 2 and a needle tube 3. The hook needle 2 includes a needle tip 21 and a needle body 22. The handle body 1 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are connected by screws or snap connections. A slot structure 13 is provided between the first housing 11 and the second housing 12, and the needle tube 3 is arranged in the slot structure 13 and clamped. The hook needle 2 is arranged in the needle tube 3. The handle body 1 is provided with a slidable pusher 4, and the tail end of the hook needle 2 is fixedly connected to the pusher 4. When the pusher 4 slides back and forth, it drives the hook needle 2 to slide in the needle tube 3 so that the needle tip 21 extends and retracts. When in use, the auxiliary needle for the quilt fastener cooperates with other fasteners. The needle tube 3 has a spiked portion 31. The quilt is punctured by using the spiked portion 31, and then the pusher 4 is pushed to push out the hook needle 2 to hook the thread on the fastener. Then the pusher 4 is pushed back to retract the hook needle 2, and then the needle tube 3 is pulled out from the quilt. The thread of the fastener is brought out through the quilt, and then the thread is fixed with another fastener, and the quilt and the quilt cover are fixed.

[0025] The needle body 22 is provided with an anti-shake structure 221 to make the hook needle 2 stable when sliding in the needle tube 3, so that the needle tip 21 does not shake when extending and retracting, which is convenient for hooking the thread. In this embodiment, the anti-shake structure 221 is a bent portion or a bent part provided on the needle body 22, and the bent portion or the bent part abuts against the inner wall of the needle tube 3, so that the hook needle 2 is stable when sliding up and down, and the needle tip 21 does not shake when extending and retracting, which is convenient for hooking the thread. In other embodiments, the anti-shake structure 221 is an anti-shake component wrapped outside the needle body 22, and the anti-shake component abuts against the inner wall of the needle tube 3. The anti-shake component can be made of plastic or wood or metal or rubber.

[0026] The needle tip 21 is bent or curved relative to the needle body 22, so that the needle tip 21 forms a fixed angle with the needle tube 3 after extending out of the needle tube 3 for convenient thread hooking. In specific applications, the range of the angle a between the needle tip 21 and the needle body 22 is 0° < a < 90°. The needle tip 21 has a hooked portion 211, and the needle tube 3 has a spiked portion 31 for puncturing the quilt. In this embodiment, the hooked direction of the hooked portion 211 is opposite to the spiked portion 31, so that the needle tip 21 opens relative to the spiked portion 31, which is convenient for the needle tip 21 to hook the thread and convenient for the needle tip 21 to retract.

[0027] The pusher 4 includes a base 42 and a push button 41. The second housing 12 is provided with a slide rail 121 for restricting the sliding direction of the base 42, and the base 42 is provided with a groove portion 424 that cooperates with the slide rail 121. The first housing 11 is provided with a limit hole 111 for exposing the push button 41, so that the push button 41 can only slide within the limit hole 111, thereby restricting the sliding distance of the hook needle 2. The second housing 12 is provided with a first limit portion 122 and a second limit portion 123 for restricting the sliding range of the pusher 4. The base 42 slides between the first limit portion 122 and the second limit portion 123, thereby restricting the sliding distance of the hook needle 2. The base 42 is provided with a mounting portion 421 for mounting the hook needle 2. The mounting portion 421 is provided with a mounting groove 422 for inserting the hook needle 2, and a locking screw 423 is provided on the mounting groove 422 to lock the hook needle 2.

[0028] An elastic member 5 is provided between the pusher 4 and the handle body 1 so that the needle tip 21 automatically retracts and resets after extending. In this embodiment, the elastic member 5 is a spring, and in other embodiments, it can be a spring piece. A first baffle 425 is provided on the mounting portion 421, and a second baffle 124 is provided on the second housing 12. The elastic member 5 is provided between the first baffle 425 and the second baffle 124, and the elastic member 5 is sleeved on the hook needle 2 to prevent displacement during use. In this embodiment, the second baffle 124 is the first limit portion 122. In other embodiments, the second baffle 124 and the first limit portion 122 can be provided as different components.

[0029] A cap 6 for covering the syringe barrel 3 and the hook needle 2 is provided on the handle body 1.

[0030] The above schematically describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
