[0014] Compared with the prior art, at least one of the above one or more technical solutions in the needle-type suction cup provided by the embodiment of the present invention has the following technical effects:

[0015] 1. When in use, applying force to the pressing part can make the driving shaft move in the first direction to compress the spring. At this time, the driving shaft drives the needle through the gear to slide forward, so that the tip part retracts into the connecting cavity through the needle hole; since the tip part is formed by gradually reducing the size along the length direction of one end of the needle, and the forward sliding direction of the needle is parallel to its length direction, it is not easy to hook out the woven thread and damage the fabric when the needle releases the fabric; when the external force applied to the pressing part is released, the spring elastically expands to drive the driving shaft to move in the second direction. At this time, the driving shaft drives the needle to slide backward through the gear, so that the tip part passes through the needle hole and extends outside the connecting cavity, facilitating the picking of the fabric. The directions between the forward and backward slides of the needle are opposite, making it smoother when the needle releases the fabric and not easy to hook the woven thread, which is beneficial to keeping the fabric surface flat for use and sales.

[0016] 2. There are two needles, and the included angle between the length directions of the two needles is greater than 0°, so that the two needles can pick the fabric in different directions, making the picking more stable and the fabric not easy to fall off. Description of the Drawings

[0034] In the first embodiment of the present utility model, a needle-type suction cup is provided for picking up fabrics. Refer to Figures 1 - 6 , which includes a suction cup main body; the suction cup main body includes:

[0035] A housing 1 for support and protection, which is provided with a connection cavity 2; an opening 11 communicating with the connection cavity 2 is provided on the outer side wall of one end of the housing 1, and a needle hole 12 communicating with the connection cavity 2 is provided on the outer side wall of the other end of the housing 1. The needle hole 12 can be set in a long strip shape or a round hole shape; and

[0036] A suction cup needle assembly 3 is disposed in the connection cavity 2 and includes a driving shaft 31 and a needle 33. The needle 33 is used for picking up fabrics, and the driving shaft 31 is used to drive the needle 33 to move; the driving shaft 31 and the connection cavity 2 are elastically connected by a spring 32. One end of the driving shaft 31 passes through the opening 11 to form a pressing portion 311; applying force to the pressing portion 311 can make the driving shaft 31 move in a first direction to compress the spring 32; when the force applied to the pressing portion 311 is released, the spring 32 elastically expands to make the driving shaft 31 move in a second direction, and the first direction and the second direction are opposite to each other; the needle 33 is slidably connected to the connection cavity 2; wherein,

[0037] The lancet 33 is provided with two lancets 33, and the included angle between the length directions of the two lancets 33 is greater than 0°, so that the two lancets 33 are arranged in a staggered manner; one end of the lancet 33 is tapered along its length direction to form a pointed end 331, and the pointed end 331 can be adapted to pass through the needle hole 12 to extend outside the connection cavity 2 or retract into the connection cavity 2; the lancet 33 and the drive shaft 31 are meshed and connected through a gear 34, and the gear 34 is rotatably connected to the inner side wall of the connection cavity 2; when the drive shaft 31 moves in the first direction, it can drive the lancet 33 to slide in the positive direction, so that the pointed end 331 passes through the needle hole 12 and retracts into the connection cavity 2; when the drive shaft 31 moves in the second direction, it can drive the lancet 33 to slide in the reverse direction, so that the pointed end 331 passes through the needle hole 12 and extends outside the connection cavity 2; the positive and reverse directions are opposite to each other and are both parallel to the length direction of the lancet 33.

[0038] During use, applying force to the pressing part 311 can cause the drive shaft 31 to move in the first direction to compress the spring 32. At this time, the drive shaft 31 drives the lancet 33 to slide in the positive direction through the gear 34, so that the pointed end 331 passes through the needle hole 12 and retracts into the connection cavity 2; because the pointed end 331 is formed by tapering the size of one end of the lancet 33 along its length direction, and the positive sliding direction of the lancet 33 is parallel to its length direction, when the lancet 33 releases the fabric, it is not easy to hook out the yarn and damage the fabric; when the external force applied to the pressing part 311 is released, the spring 32 elastically expands to drive the drive shaft 31 to move in the second direction. At this time, the drive shaft 31 drives the lancet 33 to slide in the reverse direction through the gear 34, so that the pointed end 331 passes through the needle hole 12 and extends outside the connection cavity 2, which is convenient for picking up the fabric. The positive and reverse directions of the lancet 33 sliding are opposite to each other, making the lancet 33 release the fabric more smoothly and not easy to hook the yarn.

[0039] In another embodiment of the present invention, refer to Figure 5 and Figure 6 , the two lancets 33 are respectively arranged on both sides of the drive shaft 31.

[0040] Furthermore, a number of drive tooth grooves 312 are arranged at equal intervals along the length direction on the outer side of the drive shaft 31, and a number of needle tooth grooves 332 are recessed at equal intervals along the length direction on the outer side of the lancet 33. The drive tooth grooves 312 and the needle tooth grooves 332 are both adapted to be meshed with the gear 34; there are two groups of drive tooth grooves 312, and the two groups of drive tooth grooves 312 are respectively arranged on both sides of the drive shaft 31 to be meshed and connected with the two gears 34.

[0041] Preferably, the gear 34 is set in a long shape, so that the positions of the drive shaft 31 and the lancet 33 on the gear 34 can be staggered from each other, so as to facilitate the staggered arrangement between the two lancets 33, and the two lancets 33 are not easy to collide with the drive shaft 31 and cause damage.

[0042] In another embodiment of the present utility model, the intersection point between the length directions of the two needle pricks 33 is located on the central axis of the drive shaft 31, making the connection between the drive shaft 31 and the needle pricks 33 firm and facilitating the needle pricks 33 to pick up the fabric.
