One end of the inclined surface a on the L-shaped tie rod 36 is movably overlapped with the outer side of the pressure block 39. The pressure block 39 is slidably sleeved on the outer side of the guide seat 310 with an isosceles trapezoidal cross-section. The length of the guide seat 310 is greater than that of the pressure block 39. A spring b312 is fixedly connected to one side wall of the pressure block 39 through a connecting block b313.

One end of the slope c on the pressure block 39 is movably overlapped on the top of the pressure long rod 32, and the pressure long rod 32 is movably inserted on the support seat 2. One end of the pressure long rod 32 away from the slope c is fixedly connected to the outer side of the vertical plate 5, and the other end of the pressure long rod 32 is provided with a slope d that cooperates with the slope c.

[0030] The bottom end of the guide seat 310 is movably fitted to the top end of the pressing rod 32. Figure 4 In the figure, spring a38 is in a stretched state and spring b312 is in a compressed state.

[0031] Further as Figure 1-4 As shown, it is worth explaining in detail that in order to enable the clamped transmission shaft to rotate so as to meet the needs of fine processing by an external processing device, a driving structure is provided, including a motor a25 fixedly connected to the back of the support seat 2, and the output shaft of the motor is fixedly connected to a gear b24, and a gear a23 is meshingly connected to the bottom of the gear b24, and the gear a23 is fixedly connected to the outer side of the rotating rod 21.

At the same time, the inclined surface d of the long pressing rod 32 will resist the upward movement of the pressing block 39, causing the spring b312 to be compressed. In addition, the pressing block 39 will simultaneously resist the L-shaped pull rod 36 to move to the left, so that the movable rod 35 will drive the human-shaped block 33 to move to the left, and then cooperate with the action of multiple push-pull rods 34, so that the three clamping blocks 31 can clamp and fix one end of the transmission shaft, so that the clamping and tightening can be achieved simultaneously, which greatly improves the efficiency of subsequent finishing and has a good use effect.
