[0006] As a further improvement of the present application, the rotary clamp includes a base sleeve, which is arranged on the outside of the socket and fixedly connected to the support. The inner ring of the base sleeve is rotatably connected to a connecting sleeve, one end of the connecting sleeve is fixedly connected to a swivel, and the outer ring of the swivel is fixedly connected to a gear belt.

[0007] As a further improvement of the present application, one end of the swivel is fixedly connected to a swing pipe, the outer wall of the swing pipe is penetrated by a plurality of evenly distributed linkage rods which are slidably connected thereto, one end of the linkage rod is fixedly connected to a semi-clamping ring, and the other end of the linkage rod is fixedly connected to a counterweight block.

[0008] As a further improvement of the present application, an outer frame is fixedly connected to the outer wall of the swing pipe near the linkage rod, the outer frame is sleeved on the outside of the linkage rod, and a return spring is fixedly connected between the outer wall of the linkage rod and the top of the outer frame.

[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

An outer rod 701 is fixedly connected to the wall, an inner rod 702 is fixedly connected to the side wall of the inner piston 707, a grinding belt 703 is fixedly connected between the inner rod 702 and one end of the two outer rods 701, an energy supply pipe 8 is fixedly connected to the middle part of the top plate 6, the interior of the energy supply pipe 8 is filled with hydraulic oil, a driving piston 801 is slidably connected to the inner wall of the energy supply pipe 8, the energy supply pipe 8 is located on one side of the driving piston 801 and is set as a right chamber 802, and the energy supply pipe 8 is located on the other side of the driving piston 801 and is set as a left chamber 803, one end of the energy supply pipe 8 is fixedly connected to an electric telescopic rod 804, the movable end of the electric telescopic rod 804 is fixedly connected to the driving piston 801, the right chamber 802 is connected to multiple external pressure tubes 704 through an external connecting pipe 805, and the left chamber 803 is connected to multiple internal pressure tubes 705 through an internal connecting pipe 806.

[0025] In the initial state, the inner rod 702 and one end of the two outer rods 701 are of equal length. When polishing, the test tube is inserted into the socket 4, and the holder 5 is rotated to fix the test tube, and the inner rod 702 is inserted into the test tube, and the two outer rods 701 are located outside the test tube. At this time, the polishing belt 703 is in a W shape, and the rotating holder 5 drives the test tube to rotate, so that the end surface of the test tube mouth can be polished;

[0026] After the end surface of the test tube mouth is polished, the electric telescopic rod 804 drives the driving piston 801 to move rightward, at which time the inner rod 702 extends outward, the outer rod 701 contracts inward, and the polishing belt 703 is in a < shape to polish the inner angle of the test tube mouth;

[0028] Through the above arrangement, not only can test tubes with different diameters be polished, but also different positions of the test tube openings can be polished more comprehensively, thereby improving the polishing effect of the test tubes.

[0029] The second implementation method:

[0030] Figure 1 and 6 -7 shows an experimental equipment edge grinding device, which is different from the first embodiment in that the rotary clamp 5 includes a base sleeve 501, which is sleeved on the outside of the socket 4 and fixedly connected to the support 2, the inner ring of the base sleeve 501 is rotatably connected to a connecting sleeve 502, one end of the connecting sleeve 502 is fixedly connected to a swivel 503, the outer ring of the swivel 503 is fixedly connected to a gear belt, one end of the swivel 503 is fixedly connected to a swing tube 504, the outer wall of the swing tube 504 is penetrated by a plurality of evenly distributed linkage rods 505, one end of the linkage rod 505 is fixedly connected to the outer wall of the swing tube 504, and the outer wall of the swing tube 504 is slidably connected to the outer wall of the swing tube 504.

[0031] When the test tube passes through the socket 4 and passes through the swing tube 504, the motor 9 is started to drive the multiple rotating rings 503 to rotate through the driving gear 901. When the rotating ring 503 rotates, the multiple linkage rods 505 are moved in the direction away from the test tube under the action of centrifugal force, so that the semi-clamping ring 506 can clamp the test tube and can fix test tubes of different diameters. When the test tube is polished, the rotating ring 503 stops rotating, and the multiple semi-clamping rings 506 are separated from the test tube, so that the test tube can be easily taken out of the rotating clamp 5. Through the above arrangement, the test tube is clamped and fixed by the rotating force during the test tube polishing. Compared with the traditional motor-driven clamping, the clamping cost of the test tube is saved.

[0032] One end of the inner rod 702 is fixedly connected to the guide rod 10, and one end of the guide rod 10 extends to the inner side of the socket 4.

A top spring 303 is fixedly connected between one end of the electric cylinder 302 and the bottom end of the top plate 6; through the above arrangement, the electric cylinder 302 can push the polishing belt 703 to fit tightly against the test tube mouth through the top plate 6, thereby improving the polishing effect of the test tube.

[0033] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
