When the upper end of the first supporting arm 11 and the upper end of the second supporting arm 12 are close to each other to clamp the silicon rod 3, the first enclasping block 13 and the second enclasping block 14 are close to each other to enclasp the silicon rod 3, and as the first enclasping block 13 is rotationally connected to the upper end of the first supporting arm 11 and the second enclasping block 14 is rotationally connected to the upper end of the second supporting arm 12, when enclasping the silicon rod 3, the outer circumferential surface of the silicon rod 3 cannot be matched with at least one of the first enclasping block 13 and the second enclasping block 14, after the corresponding enclasping block is contacted with the outer circumferential surface of the silicon rod 3, the outer circumferential surface of the silicon rod 3 can press the corresponding enclasping block to rotate, so that the enclasping block can rotate to be matched with the outer circumferential surface of the silicon rod 3 to enable the silicon rod 3 to be enclasped better.

For example, the diameter of the silicon rod 3 is smaller, so that the overall position of the silicon rod 3 is also lower, when the first enclasping block 13 and the second enclasping block 14 are close to each other, the lower ends of the first enclasping block 13 and the second enclasping block 14 are firstly contacted with the silicon rod 3, the first enclasping block 13 and the second enclasping block 14 are continuously close to each other, and are limited by the silicon rod 3, the first enclasping block 13 and the second enclasping block 14 can both rotate downwards until the upper ends of the first enclasping block 13 and the second enclasping block 14 are also contacted with the peripheral surface of the silicon rod 3, so that the two enclasping blocks can be ensured to effectively enclasp the silicon rod 3; similarly, when the diameter of the silicon rod 3 is larger, the upper ends of the first enclasping block 13 and the second enclasping block 14 are contacted with the silicon rod 3 when the first enclasping block 13 and the second enclasping block 14 are close to each other, the first enclasping block 13 and the second enclasping block 14 are continuously close to each other and are limited by the silicon rod 3, and the first enclasping block 13 and the second enclasping block 14 can both rotate upwards until the lower ends of the first enclasping block 13 and the second enclasping block 14 are also contacted with the peripheral surface of the silicon rod 3, so that the two enclasping blocks can ensure that the silicon rod 3 can be enclasped effectively.

Further, referring to fig. 2, the first enclasping block 13 is disposed opposite to the second enclasping block 14, the first enclasping block 13 rotates around a first direction, the second enclasping block 14 rotates around a second direction, the first direction is parallel to the second direction, and the first direction is perpendicular to the opposite direction of the first enclasping block 13 and the second enclasping block 14.

The first direction and the second direction are both horizontal directions and are perpendicular to the opposite directions of the first enclasping block 13 and the second enclasping block 14, so that the first enclasping block 13 and the second enclasping block 14 can only rotate in the vertical direction, and the first enclasping block 13 and the second enclasping block 14 can be ensured to be capable of effectively enclasping the silicon rod 3.

In an alternative embodiment, the first enclasping block 13 and the second enclasping block 14 have the same structure, and the enclasping block includes a connecting arm 131, a first limiting block 132 and a second limiting block 133, where the connecting arm 131, the first limiting block 132 and the second limiting block 133 are connected at the same place, one end of the connecting arm 131 far away from the first limiting block 132 and the second limiting block 133 is provided with a first rotating hole, and the corresponding supporting arm is provided with a second rotating hole, where the first rotating hole and the second rotating hole are connected through a rotating shaft.

Of course, in other embodiments, the support arm may be fixedly connected with a rotation shaft, and the rotation shaft is rotatably matched with the second rotation hole on the support arm, so that the support arm can rotate around the second rotation Kong Baidong; alternatively, the shaft is fixed to the support arm, and the shaft is rotatably fitted to the first rotation hole of the connection arm 131.

In an alternative embodiment, the support arm is provided with a avoiding groove 111, the second rotating hole is communicated with the avoiding groove 111, and a part of the connecting arm 131 extends into the avoiding groove 111, and the avoiding groove 111 has a certain length in the height direction, so that the connecting arm 131 can swing in the avoiding groove 111.

The first stop surface corresponds to a side of the first stop block 132 facing the support arm, and the second stop surface corresponds to a side of the second stop block 133 facing the support arm.

The up-and-down swing amplitude of the clasping block is limited, specifically, when the clasping block swings upward, at most the back surface (the surface facing the support arm) of the first stopper 132 contacts with the first stop surface; when the enclasping block swings downwards, at most the back surface of the second limiting block 133 is contacted with the second stop surface, so that the up-and-down swing amplitude of the enclasping block is limited. So that the enclasping block can only swing within a certain range to adapt to the silicon rod 3 with limited diameter variation; moreover, if the downward pivoted amplitude of the enclasping block is too large, when two supporting arms are mutually close to enclasping the silicon rod 3, the situation that the top surface of the upper limiting block props against the lower side of the silicon rod 3 can occur, so that the silicon rod 3 cannot be enclasped, the novel enclasping block is limited by two stop surfaces, and the enclasping surface basically faces the silicon rod 3, so that the silicon rod 3 can be ensured to be effectively enclasped, and the occurrence of unexpected situations is avoided.

In the above embodiment, the support arm itself is configured to actually hold the rotation amplitude of the block, so that the holding block can only swing within a set range.

Further, referring to fig. 4 and 5, a first mounting groove 134 is formed on the first stop surface, a first elastic member 136 is disposed in the first mounting groove 134, and a portion of the first elastic member 136 exposes the first mounting groove 134 and cooperates with the first stopper 132; the second stop surface is provided with a second mounting groove 135, a second elastic member 137 is arranged in the second mounting groove 135, and a part of the second elastic member 137 exposes out of the second mounting groove 135 and is matched with the second limiting block 133.

When the silicon rod 3 is held tightly by the holding block, the two supporting arms move inwards (approach each other), and at the moment when the holding block is contacted with the silicon rod 3, for example, the first limiting block 132 is contacted with the silicon rod 3, the holding block can swing upwards, if the contact speed is too high, the first limiting block 132 can bounce upwards, rebound occurs after impacting the first limiting surface, and the silicon rod 3 is impacted, so that the silicon rod 3 is at risk of being impacted and damaged; the first elastic member 136 is arranged, and the first elastic member 136 can prop against the first limiting block 132 from the back surface, so that the first limiting block 132 is always in contact with the silicon rod 3 (the first limiting block 132 cannot spring upwards), and the situation that the silicon rod 3 is broken by collision is avoided; similarly, the second elastic member 137 will prop against the second limiting block 133 from the back surface, so as to avoid the second limiting block 133 from breaking the silicon rod 3.
