[0002] Embroidery, dating back to ancient times, is a traditional handicraft. It involves using needles to sew threads and fabric together to create beautiful patterns, images, and words. When embroidering, the fabric needs to be stretched flat to facilitate sewing and needlework, ensuring the finished embroidery remains flat and the pattern does not deform. However, holding the flattening tool for a long time can cause hand fatigue and increase the difficulty of embroidery. Therefore, a stand is needed to hold and adjust the flattening tool. Utility Model Content

[0003] The purpose of this utility model is to provide a three-dimensional support frame for hand-embroidered shirts, so as to solve the problem mentioned in the background art that it is inconvenient and tiring to pick up and sew embroidered shirts.

[0005] Preferably, the lifting and engaging mechanism includes: a pin, which is slidably mounted on one end side surface of the movable sleeve, and the end of the pin near the intermediate support rod is inclined, and the intermediate support rod engages with the movable sleeve, the plane of the intermediate support rod is provided with an engaging groove, and the engaging groove engages with the pin, and a first spring is provided between the pin and the movable sleeve.

[0006] Using the above technical solution, when adjusting the height of the movable sleeve, the movable sleeve can be pulled upwards directly. The weight of the movable sleeve and the engagement of the pin and the locking groove make it possible to remove the movable sleeve without adjustment.

[0007] Preferably, a limiting groove is provided at the end of the intermediate support rod away from the base, and the limiting groove is located at the upper end of the engaging groove.

[0008] Using the above technical solution, when the movable sleeve is pulled out to the top of the middle support rod, the first spring will push the pin, causing the pin to engage in the limit slot, preventing the movable sleeve from being pulled out directly.

[0009] Preferably, an elastic locking mechanism is provided between the movable sleeve and the adjusting support rod, which allows the angle of the adjusting support rod to be easily adjusted and fixed.

[0010] By adopting the above technical solution, the angle of the adjustment support rod can be adjusted without turning the adjustment mechanism, and the adjustment support rod can be automatically fixed after adjustment.

[0011] Preferably, the elastic engagement mechanism includes: a first ratchet gear, which is fixedly installed on both outer surfaces of the movable sleeve, and an adjusting support rod is rotatably installed on the outer surface of the movable sleeve. A second ratchet gear is fixedly installed on the side surface of the adjusting support rod near the movable sleeve, and the second ratchet gear engages with the first ratchet gear. The first and second ratchet gears are concentrically designed. A synchronous connecting rod is fixedly installed on the end of the adjusting support rod near the movable sleeve, and one end of the synchronous connecting rod passes through the outer surface of another adjusting support rod. An adjusting knob is threaded onto the side surface of the adjusting support rod, and a second spring is provided between the adjusting knob and the adjusting support rod. The second spring, the adjusting knob, the second ratchet gear, and the first ratchet gear are concentrically designed.

[0012] By adopting the above technical solution, the thrust applied by the second spring to the adjusting support rod can be adjusted by tightening the adjusting knob, thereby increasing the pressure between the first ratchet and the second ratchet, so that when the angle of the adjusting support rod is changed, the first ratchet and the second ratchet can automatically engage to position the adjusting support rod.

[0013] Preferably, a rotating insert block is rotatably mounted on the end of the adjusting support rod away from the movable sleeve, and a fastening knob is threaded onto the outer surface of the rotating shaft of the adjusting support rod and the rotating insert block, and the side surface of the fastening knob is in contact with the outer surface of the adjusting support rod. Through holes are opened on both sides of the rotating insert block, and an insertion connector is inserted inside the rotating insert block. The insertion connector is provided with an elastic pin inside, and the elastic pin of the insertion connector engages with the through hole of the rotating insert block.

[0014] Using the above technical solution, the angle of the rotating insert block can be fixed by tightening the knob, and the insert connector can be easily inserted into and removed from the rotating insert block, allowing the inner elastic frame to be removed and taken out.

[0015] Preferably, an inner elastic frame is rotatably mounted on the side surface of the insertion connector, and a notch is provided at the end of the inner elastic frame away from the rotatable insertion block. The inner elastic frame is made of elastic material, and an outer fixing ring is engaged on the outer surface of the inner elastic frame.

[0016] By adopting the above technical solution, the angle of the inner elastic frame can be changed to make embroidery easier. At the same time, through the elasticity of the inner elastic frame and the engagement of the outer fixing ring, fabrics of different thicknesses can be fixed on the inner elastic frame, making it convenient to install and remove the fabric.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the three-dimensional support frame for this hand-embroidered shirt:

[0018] 1. When it is necessary to adjust the height of the fabric during embroidery, the movable sleeve can be pulled directly to move it along the direction of the central support rod. The inclined surface of the pin is in contact with the side surface of the locking groove. As the movable sleeve moves, the pin is squeezed into the movable sleeve. When it reaches the desired position, the first spring will push the pin out, so that the pin engages with the locking groove and fixes the movable sleeve. This allows for direct upward adjustment without other operations, adjusting the embroidery height, making the worker more comfortable and reducing hand fatigue.

[0019] 2. When it is necessary to adjust the angle of the adjustment support rod, the adjustment support rod can be directly pressed and lifted. This will cause the second spring, which is compressed by the adjustment knob, to push the adjustment support rod, increasing the pressure between the first ratchet and the second ratchet. This will allow the second ratchet to automatically jump when the adjustment support rod is rotated, changing the angle of the adjustment support rod. After the adjustment is completed, the adjustment support rod will automatically be fixed, making it convenient for the operator to adjust the angle.

[0020] 3. By rotating the insert block and the insertion connector, the inner elastic frame of the fabric can be easily fixed on the adjusting support rod. At the same time, by rotating the inner elastic frame, the angle of the inner elastic frame on the adjusting support rod can be adjusted, so that the operator can adjust to the optimal operating angle when embroidering. It is also convenient to remove the inner elastic frame for storage to prevent dust and damage from foreign objects. Attached Figure Description
