Description of the invention: [Technical field to which the invention pertains] The present invention relates to the field of lens manufacturing technology, and more particularly to a clamping device for holding an ejection member with an optical element to be cut. [Prior Art] At present, the lens is mostly made of glass or plastic, and its manufacturing technology is relatively mature. Generally, it is produced by an injection molding process. Specifically, the injection molding process includes injection, pressure holding, cooling, demoulding, shearing, and the like. Subsequent processing and other steps. Referring to Figure 1, there is shown a schematic view of an injection element 10 with a plastic lens to be cut which is ejected by an injection molding machine. The injection element 1A includes a semi-finished product of a plastic lens 12 formed by four molds of a die. The four lenses η are located on the same circumference and are connected to each other by the runner head 14 and the runner head 16. After the lens 12 is formed, it is conveyed to the shear zone together with the runner head 12 and the runner head 16 for shearing to separate it from the scrubbing head 14 and the runner head Φ 16. When the plastic lens 12 is being cut, the runner head 14 and the runner head 16 are fixed by means of a holding device 23. Referring to Figure 2, the top of the clamping device 22 is provided with two grooves 23 for holding the flow path head 16. The two grooves 23 are respectively distributed in the radial direction of the same circumference and intersect at the center of the circumference. When cutting, the flow path head 16 is first accommodated in the groove 23, and the lens 12 is placed outside the groove μ, and then the lens shearing machine can perform the cutting operation. In order to increase production efficiency, mold-molded lenses having eight, sixteen or even more mold cavities are usually used in production. As the number of cavities increases, that is, the number of lenses arranged on the circumference of 201010852 ' increases, causing the radius of the circumference to increase, that is, the length of the 々·! track increases, which requires the length of the groove to be correspondingly increased, and the clamping The grooves 23 of the device 22 are of limited length, i.e., the molds for the different number of cavity numbers need to be arranged one by one with a groove having a groove corresponding to the size of the flow path, which undoubtedly increases the production cost. In addition, when a mirror is produced using a mold having a different number of cavities, it is necessary to replace the corresponding holding device, which will reduce the production efficiency. In view of the above, it is an object of the present invention to provide a holding device capable of fixing an optical component for producing a crucible from a mold having a different number of cavities to save production cost and increase production efficiency. SUMMARY OF THE INVENTION The following is an example of a holding device for fixing a lens produced by a mold having a different number of cavities. The clamping device is used to clamp the injection element. The ejection element includes at least one material to be removed and an optical element to be sheared connected to the material. The clamping device includes a clamping portion, a fixing portion and a plurality of supporting portions. The clamping portion includes an elastic body and a plurality of clamping members. The plurality of holding members are connected to each other by the elastic body. Each of the support portions is connected to the fixed portion, and the other end is connected to a corresponding holding member for engaging the elastic member to support the corresponding holder member on the same circumference centered on the fixing portion. The end of each of the clamping members is formed to receive the material. In the clamping device of the present invention, since the member is located on the circumference centered on the fixing portion, the distance between the elastic member and the fixed shaft can be adjusted to the length of the flow path of the mold. Therefore, the clamping device of the 201010852 technical solution can be applied to the injection components for fixing the molds of different cavities, thereby saving cost and improving production efficiency. [Embodiment] The holding device provided by the present technical solution will be described in detail below with reference to the embodiments and the accompanying drawings. Referring to FIG. 3 and FIG. 4 together, the clamping device 100 provided by the embodiment of the present invention includes a clamping portion 110, a fixing portion 120, and a plurality of supporting portions 130. The clamping portion 110 is located on a circumference centered on the fixing portion 120. Each of the support portions 130 is disposed in the radial direction of the circumference, and has one end connected to the fixing portion 120 and the other end connected to the clamping portion 110. The clamping portion 110 includes an elastic body 1 and a plurality of clamping members 112 which are arcuate cylinders. The elastic body 111 penetrates through each of the holding members 112 so as to be engaged with the respective holding members 112 to form an annular structure. Elastomer 112 can be a spring, rubber band or other resilient member. Specifically, the clamping member 112 has an end surface 1121, a first side surface 1122, a second side surface 1123, and an inner wall 1124. The first side surface 1122 and the second side surface 1123 are respectively connected to the end surface 1121, and the first side surface 1122 is opposite to the second side surface 1123. The inner wall 1124 is located between the first side surface 1122 and the second side surface 1123, and is respectively opposite to the first side surface 1122. The second side surface 1123 and the end surface 1121 are connected. The end portion of the holding member 112 including the end surface 1121 is provided with a notch 1120. The notch 1120 is shaped and sized to match the shape and size of the removal head to receive the head and to position the lens to be sheared outside of the area in which the holders 112 are enclosed. The clamping member 112 is provided with a first receiving groove 201010852 1125 and a second receiving groove 1126 from the inner wall 1124. The first receiving groove 1125 is located between the second receiving groove 1126 and the elastic body 111. The elastic body 111 penetrates the first side surface 1122' and the second side surface 1123 such that the plurality of holding members 112 are connected to each other by the elastic body 111 and are on the same circumference. The fixing portion 120 includes a fixed shaft 121 and a carrier portion 122 connected to the fixed shaft 121. The fixed shaft 121 has a cylindrical shape and includes a clamping surface 1211 for continuously carrying the runner head of the ejection member. The fixed shaft 121 is provided with a plurality of third receiving grooves 1202 and a plurality of fourth receiving grooves 1203 from the side wall 1201 to the inside of the reference portion. The third receiving groove 1202 is located between the fourth receiving groove 1203 and the elastic body 111. The number of the third receiving slots 1202 is the same as the number of the first receiving slots 1125, and the number of the fourth receiving slots 1203 is the same as the number of the second receiving slots 1126. The carrying portion 122 is for fixing the fixed shaft 121 and the carrying nip 110. In this embodiment, the bearing portion 122 has a cylindrical shape and has a bearing surface 1221. When the bearing surface 1221 is sized such that the elastic body 111 variable reaches a maximum, the clamping portion 110 can still be carried on the fixing portion 120. Of course, the fixing portion 120 may not include the carrying portion 122, but directly change the size of the fixing shaft 121 to the fixed shaft 121 to be stably placed in the shearing device and to clamp the ejection member. The support portion 130 is a stretchable member whose length is adjustable. In this embodiment, the support portion 130 includes a support shaft 131 and an elastic member 132 disposed corresponding to the support shaft 131. The two ends of the support shaft 131 are respectively received in the first receiving slot 1125 and the third receiving slot 1202. The two ends of the elastic member 132 are respectively received in the second receiving recess 10116 and the fourth receiving slot 1203, thereby the elastic member 132 and Both ends of the support shaft '131 abut against the fixing portion 110 and the clamping member 112, respectively. The resilient member 132 can be a spring or other resilient member commonly used in the art to impart a force to the retaining member 112 along the central axis of the resilient member 132. The support shaft 131 is used to impart a force opposing the elastic force of the fixing portion 110 and the holding member 112 to the elastic member 111 to keep the distance between the holding member 112 and the fixing portion 110 constant. Of course, the two ends of the elastic member 132 can be directly welded to the side wall 1201 of the fixing portion 110 and the inner wall 1124 of the clamping member 112, respectively. In this embodiment, the elastic body 111, the elastic member 132, and the support shaft 131 between the elastic body 111 and the elastic member 132 are used to balance and fix the clamping portion 110. However, the elastic member 132 is not required. The bottom of the clamping member 112 penetrates the elastic body, and the support shaft 131 abuts against the position of the clamping member 112 between the two elastic bodies to balance and fix the clamping member 112. . Further, the number of the support portions 130 is not limited to four. The holding device of the present invention may include 2n spaced-apart support portions, each of which is separated by an angle of 360/n degrees, wherein n is an integer greater than or equal to two. The support portion 130 can also be a telescopic sleeve having a card member that is common in the art. When the two sleeves of the telescopic sleeve are moved relative to each other by stretching or compressing to make the length of the telescopic sleeve reach a required length, the latching member fixes the two sleeves of the telescopic sleeve so that the sleeve The two sleeves of the telescoping sleeve no longer create relative motion and maintain the length of the telescoping sleeve to the desired length. Further, the support portion 130 may be a constant length structure. Correspondingly, it is necessary to make a support portion that is consistent with the length of the flow path for the mold of different flow path lengths. When the injection device is fixed by the holding device, the two ends of the support portion 201010852 can be respectively abutted against the outer side walls of the clamp member 112 and the fixed shaft 121. The elastic body 111 may not penetrate the holding member 112 as long as the plurality of holding members 112 can be enclosed in an annular structure by the elastic body 111. Each of the clamping members 112 can be fixed to the elastic body 111 or can be slidably coupled to the elastic body 111. Referring to FIG. 5, it is a schematic diagram of the use of the clamping device 100 for clamping the ejection member 200 in the embodiment. The ejection element 200 includes four plastic lenses 210 to be cut. The four plastic lenses 210 are located on the same circumference centered on the sprue head 220, and are connected to each other by a sprue head 220 and eight flow heads 230. The operation of holding the plastic mirror 210 to be cut using the holding device 100 will be specifically described below. (1) The support shaft 131 and the elastic body 111 are used to adjust the distance between the clamp member 112 and the fixed shaft 121 to the length of the runner head 230, and the length is fixed by the support shaft 131. (2) An injection element @200 having four plastic lenses 210 is ejected by an injection molding machine. Usually, the plastic lens is connected with at least one material to be removed; and the maximum number of molded lenses at a time is related to the number of cavity molds of the molding die, and the more the number of cavities, the more the number of molded lenses at a time. In this embodiment, the number of mold holes for the injection molding die is four, and the maximum number of molded lenses at one time is four, that is, four plastic lenses 210 to be cut, which are fed by the runner head 220 and the four flow channels. The heads 230 are connected to each other. (3) The ejection member 200 is transported to the cutting region by the robot arm, and the flow channel head 220 connected to the plastic lens 210 is placed on the clamping surface 1211 of the fixed shaft 121, so that the flow channel head 230 is located on the fixed shaft 121. Between the clamping member 112 11 201010852 and the inside of the notch 1120, and the lens 210 is located outside the area enclosed by the clamping portion 110 ′, the plastic lens 210 to be cut is fastened. • In summary, the present invention has indeed met the requirements of the invention patent and has filed a patent application in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art in light of the present invention are intended to be included within the scope of the following claims.
