When the medical instrument 300 is clamped in the initial state, due to gravity, the first clamping rod 151 on the lower side exerts force on the medical instrument 300 through the clamping belt 153, so that the first clamping rod 151 on the lower side exerts upward force on the medical instrument 300, and the first clamping rod 151 on the lower side does not contract due to the arrangement of the second blocking block. Along with the continuous approach of the two clamping blocks 140, the medical device 300 moves upwards relative to the clamping blocks 140 under the pushing of the first clamping rod 151 on the lower side, so that the first clamping rod 151 on the upper side contacts the medical device 300, the first spring 1513 of the first clamping rod 151 on the upper side contracts and pushes the first blocking block 160 outwards, when the first blocking block 160 is pushed outwards, the first blocking block 160 drives the second blocking block through the telescopic rod 161 to release the obstruction of the corresponding first spring 1513, and the first clamping rods 151 on the upper side and the lower side can contract.

Along with the continuous approach of the two clamping blocks 140, the medical device 300 moves upwards relative to the clamping blocks 140 under the pushing of the first clamping rod 151 on the lower side, so that the first clamping rod 151 on the upper side contacts the medical device 300, the first spring 1513 of the first clamping rod 151 on the upper side contracts and pushes the first blocking block 160 outwards, when the first blocking block 160 is pushed outwards, the first blocking block 160 drives the second blocking block through the telescopic rod 161 to release the obstruction of the corresponding first spring 1513, and the first clamping rods 151 on the upper side and the lower side can contract.
As the two clamping blocks 140 get closer, the first clamping rod 151 contracts and shortens. Meanwhile, when the two first clamping rods 151 contract, the second clamping rod 152 is also extruded, the trigger rod 1521 of the second clamping rod 152 contracts towards the inside of the sleeve, so that the transmission gear 147 is driven to rotate, the transmission gear 147 rotates to drive the upper rack 145 and the lower rack 146 to move, and the more the trigger rod 1521 contracts, the closer the distance between the two first clamping rods 151 is, so that the medical instrument 300 with different sizes is adapted. The grip strip 153 contacts the outer wall of the medical device 300, so that the medical device 300 is firmly secured and the medical device 300 is gripped.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
