[0041] The clamping seat 10 provided by the embodiment optimizes the contact surface of the clamping seat 10 and the crystal holder, increases the area of the contact surface of the clamping seat 10 and the crystal holder, reduces the situation that the deformation space of the crystal holder is large due to the small contact area of the crystal holder, and further reduces the deformation of the crystal holder, thereby reducing the stress applied to the crystal bar after the deformation of the crystal holder, so that the hidden cracks of the crystal bar can be effectively reduced. Therefore, by using the clamping seat provided by the embodiment, the technical problem that the crystal bar is prone to hidden cracks when the clamping seat in the prior art clamps the crystal holder can be solved.
[0042] Specifically, the driving part 30 can be a clamping telescopic rod, and the clamping telescopic rod is telescopically arranged. Specifically, the clamping telescopic rod is a plurality of clamping telescopic rods, and the plurality of clamping telescopic rods are arranged in one-to-one correspondence with the plurality of mushroom heads 20, and the telescopic end of each clamping telescopic rod is drivingly connected with the corresponding mushroom head 20 to drive the corresponding mushroom head 20 to move towards or away from the clamping seat 10.

When the mushroom head 20 and the clamping seat 10 clamp the crystal holder, the first clamping surface 121 and the second clamping surface 122 are both in contact with the crystal holder.
[0044] In the embodiment, the opening groove 11 has a symmetry axis extending in a preset direction, and the first clamping surface 121 and the second clamping surface 122 are symmetrically arranged relative to the symmetry axis. With such a structure, the first clamping surface 121 and the second clamping surface 122 can be effectively ensured to be in contact with the crystal holder, thereby effectively increasing the contact area of the clamping surface with the crystal holder, and better contacting and supporting the crystal holder, and reducing the deformation space of the crystal holder.
[0045] Specifically, the first clamping surface 121 and / or the second clamping surface 122 is provided with a relief groove structure 13. With such a structure, when the crystal holder or the clamping seat 10 has residual silicon mud, the silicon mud can enter the relief groove structure 13 when the crystal holder is clamped, thereby avoiding the silicon mud protruding from the first clamping surface 121 or the second clamping surface 122, which can cause uneven stress on the crystal holder and deformation of the crystal holder when clamping the crystal holder, thereby better reducing the stress on the crystal bar due to deformation of the crystal holder, and reducing the risk of hidden cracks in the crystal bar.
[0046] In the embodiment, the relief groove structure 13 includes a first communication groove 131 and a second communication groove 132, and the first communication groove 131 and the second communication groove 132 are cross-connected at a preset angle. In this way, the silicon mud containing capacity of the relief groove structure 13 can be effectively improved, thereby better reducing the risk of silicon mud protruding directly from the first clamping surface 121 and the second clamping surface 122, and better reducing the risk of deformation of the crystal holder due to silicon mud protruding from the first clamping surface 121 and the second clamping surface 122, and better reducing the risk of hidden cracks in the crystal bar due to deformation of the crystal holder.

In this way, when clamped, the silicon mud can be uniformly distributed in the plurality of communication groove groups, and the silicon mud protruding from the first mounting surface or the second mounting surface can be avoided.
[0051] Specifically, one end of the first communication groove 131 close to the opening groove 11 is located on one side of the first clamping surface 121 or the second clamping surface 122 close to the opening groove 11. In this way, when the silicon mud in the first communication groove 131 is excessive and part of the silicon mud enters the opening groove 11 through the one end of the first communication groove 131 close to the opening groove 11 to discharge part of the excessive silicon mud, the silicon mud discharge capacity is improved, and the silicon mud protruding from the first clamping surface 121 or the second clamping surface 122 can be better avoided.
[0052] Specifically, one end of the first communication groove 131 far from the opening groove 11 is located on one side of the first clamping surface 121 or the second clamping surface 122 far from the opening groove 11. In this way, when the silicon mud in the first communication groove 131 is excessive and part of the silicon mud is discharged to the clamping seat 10 through the one end of the first communication groove 131 far from the opening groove 11, the silicon mud discharge capacity is improved, and the silicon mud protruding from the first clamping surface 121 or the second clamping surface 122 can be better avoided.
[0053] Specifically, one end of the second communication groove 132 close to the opening groove 11 is located on one side of the first clamping surface 121 or the second clamping surface 122 close to the opening groove 11.

[0054] Specifically, one end of the second communication groove 132 far from the opening groove 11 is located on one side of the first clamping surface 121 or the second clamping surface 122 far from the opening groove 11. By adopting the structure, when the silicon mud in the second communication groove 132 is excessive and part of the silicon mud is discharged to the clamping seat 10 through the one end of the second communication groove 132 far from the opening groove 11, the silicon mud protruding from the first clamping surface 121 or the second clamping surface 122 can be better avoided.
[0055] Specifically, the preset angle is a, 60°≤a≤120°. In this way, the first communication groove 131 and the second communication groove 132 can be better ensured to have a proper angle, so as to avoid that the angle is too small to cause a large number of first communication grooves 131 and second communication grooves 132 to be arranged, thereby affecting the structural stability of the clamping seat 10, and also avoid that the angle is too large to cause the length of the first communication groove 131 and the second communication groove 132 to be too long, thereby causing inconvenience in discharging the silicon mud.
[0056] Specifically, the width of the second communication groove 132 is equal to the width of the first communication groove 131.
[0057] Specifically, the depth of the first communication groove 131 is less than the depth of the opening groove 11, so as to avoid that the depth of the first communication groove 131 and the second communication groove 132 is too large to affect the structural stability of the clamping seat 10, thereby effectively ensuring the structural stability of the clamping seat 10.
[0058] Specifically, the depth of the first communication groove 131 is equal to the depth of the second communication groove 132.
