Description

TECHNICAL FIELD The present disclosure relates to the technical field of embroidery auxiliary tools, and specifically, to an embroidery clamping device. BACKGROUND Embroidery is traditional handicraft that involves embroidering various patterns and text on fabrics by using needles and threads, and have high artistic value and cultural significance. In an embroidering process, an embroidery frame is one of the essential tools, which is configured to fix embroidery work and facilitate operations of an embroiderer. However, the existing embroidery frame has some shortcomings. First, in the embroidering process, the fixing effect on an embroidery piece directly affects the precision of a needle and the integrity of a pattern. For example, when a small-sized embroidery piece (such as cuff embroidery and badge embroidery) is embroidered, the existing embroidery frame often uses a single clamp for clamping, which can easily cause wrinkles on an edge of the embroidery piece because of failure in flexibly adjusting a distance. When a large-sized embroidery piece (such as bed sheet embroidery and screen embroidery) is embroidered, a clamping assembly of the traditional frame lacks a guide structure, so that a clamp easily skews during adjustment. This requires repeated calibration on the position, which wastes the time and may cause the embroidery piece to shift to disrupt the coherence of a pattern due to many adjustments. In addition, angle adjustment of the existing embroidery frame relies on the rotation of the entire frame, so that the adjustment range is limited. When the embroiderer needs to switch between different stitching methods such as flat embroidery and gold thread embroidery, the embroiderer needs to frequently adjust the sitting posture or the hand posture. Long-term operation can easily cause shoulder and neck fatigue. This reduces the embroidery efficiency. Meanwhile, parts, which are in contact with the embroidery piece, of clamping components of some embroidery frames are made of hard materials. In case of a high clamping force, it is easy to damage a fabric of the embroidery piece (especially a flexible fabric such as silk and chiffon). In case of loose clamping, the embroidery piece will shake during embroidering. As a result, embroidery stitches tilt. This seriously affects the artistic value of an embroidery product. SUMMARY In order to achieve the above objective, the present disclosure provides the following technical solutions: An embroidery clamping device includes an embroidery piece clamping main body; the embroidery piece clamping main body includes an embroidery base, a rotary driving assembly, at least two groups of clamping assemblies, and a guide structure; the rotary driving assembly includes an embroidery rotating handle fixedly mounted at a bottom of the embroidery base to drive the embroidery base to rotate around an own axis; the at least two groups of clamping assemblies include a first clamping member, a second clamping member, and a rotary clamping member; the first clamping member and the second clamping member are both assembled to a side surface of the embroidery base; the rotary clamping member is movably connected to the embroidery base; the rotary clamping member is opposite to the first clamping member and cooperates with the first clamping member to clamp and fix an embroidery piece; the guide structure includes a through mounting slot formed in a middle portion of the embroidery base, and a protrusion arranged at a bottom of the first clamping member; the protrusion is adapted and mounted within the mounting through hole, and is able to slide in a length direction of the through mounting slot, to guide movement of the first clamping member; the rotary clamping member is provided with a drive member which penetrates through the through mounting slot and is connected to the first clamping member; and while driving the rotary clamping member to rotate, the drive member can drive the first clamping member to slide along the through mounting slot, to adjust a clamping distance between the first clamping member and the rotary clamping member. Preferably, the embroidery clamping device further includes a basic pedestal provided with a rotary adjustment assembly. The rotary adjustment assembly is movably connected to the embroidery rotating handle to perform secondary adjustment on a rotating angle of the embroidery rotating handle.
