The first clamping member 3 is fixed on the adjustment plate 2, and the second clamping member 4 is slidably arranged on the adjustment plate 2. The driving assembly 5 is arranged on the adjustment plate 2, and the driving assembly 5 is used to drive the second clamping member 4 to move toward or away from the first clamping member 3. When it is necessary to clamp the pin, the driving assembly 5 can be used to drive the second clamping member 4 to slide toward the direction close to the first clamping member 3, thereby realizing automatic clamping of the pin.
[0047] Reference Figure 4 In this embodiment, the first clamping member 3 includes a fixing portion 31 and a first clamping portion 32. The fixing portion 31 is located in the mounting groove 24. The fixing portion 31 is fixed to the adjustment plate 2 by a plurality of bolts, which increases the convenience for the staff to install and remove the fixing portion 31.

[0048] Reference Figure 2 and Figure 4 The second clamping member 4 includes a sliding portion 41 and a second clamping portion 42. The sliding portion 41 is located in the installation groove 24. The sliding portion 41 and the sliding portion slide together. The driving assembly 5 is used to drive the sliding portion 41 to slide toward or away from the first clamping member 3, thereby realizing automatic clamping of the pin. The second clamping portion 42 is fixed to the end of the sliding portion 41 by bolts, which increases the convenience of the staff in installing and removing the first clamping portion 32.
[0049] Reference Figure 1 and Figure 4 In this embodiment, one end of the first clamping member 3 extends out of the adjustment plate 2, and one end of the second clamping member 4 extends out of the adjustment plate 2. Specifically, the first clamping portion 32 and the second clamping portion 42 are located at the same end of the adjustment plate 2, and the first clamping portion 32 and the second clamping portion 42 both extend out of the end of the adjustment plate 2. Since the first clamping portion 32 and the second clamping portion 42 both extend out of the end of the adjustment plate 2, the convenience of the first clamping member 3 and the second clamping member 4 clamping the pin is increased.
[0050] Reference Figure 2 and Figure 4A plurality of positioning rods 21 are fixedly arranged on the adjustment plate 2, and the plurality of positioning rods 21 are arranged at intervals along the first direction.

The outer wall of the positioning portion 61 abuts against the inner wall of the positioning groove 33. The guide portion 62 slides and cooperates with the first guide groove 43. The positioning groove 33 has a positioning effect on the positioning portion 61, which not only increases the efficiency of the staff in installing the first guide block 6, but also increases the firmness of the first guide block 6 installed on the first clamping member 3; because the guide portion 62 slides and cooperates with the first guide groove 43 on the second clamping member 4, the sliding stability of the second clamping member 4 is increased.
[0053] Continue to refer to Figure 5 The cross section of the guide portion 62 is T-shaped, and the first guide groove 43 is a T-shaped groove. The guide portion 62 not only guides the second clamping member 4, but also prevents the second clamping member 4 from falling off, further increasing the sliding stability of the second clamping member 4.
[0054] Reference Figure 2 and Figure 4 The driving assembly 5 includes a driving member 51 and a linkage member 52. The linkage member 52 is rotatably connected to the adjustment plate 2. The driving member 51 is disposed on the adjustment plate 2 and is used to drive the linkage member 52 to rotate. The linkage member 52 is slidably matched with the second clamping member 4. Since the linkage member 52 is slidably matched with the second clamping member 4, the linkage member 52 is driven to rotate by the driving member 51. When rotating, the linkage member 52 drives the second clamping member 4 to move toward or away from the first clamping member 3, thereby realizing automatic clamping of the pin.
[0055] Reference Figure 4 and Figure 6Specifically, the linkage member 52 includes a rotating portion 521 and a protruding portion 522, wherein the rotating portion 521 is fixedly connected to the protruding portion 522, and the protruding portion 522 is cylindrical.

A waist-shaped groove 44 is provided on the sliding portion 41, and the waist-shaped groove 44 extends along the first direction, and the protruding portion 522 is slidably matched with the waist-shaped groove 44. The driving member 51 drives the rotating portion 521 to rotate, and the rotating portion 521 drives the protruding portion 522 to rotate when rotating. Since the protruding portion 522 is slidably matched with the waist-shaped groove 44 on the sliding portion 41, the protruding portion 522 drives the second clamping member 4 to move toward or away from the first clamping member 3 during the rotation process, thereby realizing automatic clamping of the pin. In this embodiment, the specific driving member 51 can be a cylinder.
[0056] The implementation principle of the above embodiment is: since the clamping mechanism is arranged on the adjustment plate 2, and the adjustment plate 2 is slidably matched with the base plate 1, the position of the clamping mechanism can be adjusted by adjusting the position of the adjustment plate 2, and the automatic clamping of the pin is facilitated by the clamping mechanism.
