A second moving mechanism 5 is movably installed on the side of the two first clamping mechanisms 4 that is far apart from each other. A connecting mechanism 6 is threaded to the outer side of the two second moving mechanisms 5. A second clamping mechanism 7 is movably sleeved on the inner side of the two connecting mechanisms 6, and the second clamping mechanism 7 is located on the upper side of the first clamping mechanism 4.

[0030] The first clamping mechanism 4 includes a mechanism platform 41. Two clamping platforms 42, distributed front to back, are movably sleeved on the inner side of the mechanism platform 41. A V-shaped opening is provided on the side of the clamping platform 42 away from the second moving mechanism 5. Several linearly distributed limiting rods 43 are fixedly connected to the left side of each of the two clamping platforms 42. The outer side of the limiting rods 43 is movably sleeved on the inner side of the left wall of the mechanism platform 41. Springs 44 are movably sleeved on the outer side of each of the several limiting rods 43. The springs 44 are located on the inner side of the mechanism platform 41. The lower side of the mechanism platform 41 is threadedly connected to the outer side of the first moving mechanism 3.

[0031] The connecting mechanism 6 includes a connecting plate 61. The lower side of the connecting plate 61 is slidably connected to the upper side of the mechanism platform 41. The front and rear protrusions of the connecting plate 61 are fixedly connected to the front and rear sides of the second moving mechanism 5. A T-shaped groove 62 is provided in the middle of the upper side of the connecting plate 61. The lower side of the second clamping mechanism 7 is slidably connected to the inner side of the T-shaped groove 62.

[0032] It needs to be explained that the first moving mechanism 3 contains a first screw rod and a first motor, the first screw rod is a bidirectional screw rod, the bottom of the mechanism table 41 is threadedly connected to the outside of the first screw rod, the first motor drives the first screw rod to rotate to make the two mechanism tables 41 move in the opposite directions, when the clamping tables 42 are close to each other and contact the component to be clamped, the clamping tables 42 are stationary, and as the mechanism tables 41 continue to approach, the springs 44 are compressed, the second moving mechanism 5 contains a second motor, a second screw rod, a threaded seat and the like, the bosses on the front and back sides of the connecting plate 61 are fixedly connected to the second screw rod, the second motor drives the threaded seat to rotate, the threaded seat is threadedly connected to the outside of the second screw rod, so that the threaded seat drives the second screw rod to move left and right, thereby controlling the connecting plate 61 to move left and right on the upper side of the mechanism table 41, and thereby making the second clamping mechanism 7 move left and right, the second clamping mechanism 7 and the first clamping mechanism 4 contain components of the same shape and size.

[0033] As shown in Figure 4 , Figure 5 , the inner sides of the two clamping tables 42 are movably sleeved with quick release assemblies 45, the quick release assemblies 45 include cross plates 451, the outer sides of the cross plates 451 are movably sleeved in the inner sides of the clamping tables 42, the upper sides of the clamping tables 42 close to the inner sides of the round holes on the front and back sides are rotatably connected with vertical rods 452, the outer sides of the two vertical rods 452 are movably sleeved with clamping pipes 453, and the outer sides of the clamping pipes 453 are movably sleeved in the clamping holes on the side of the cross plate 451 close to the spring 44.

[0034] It needs to be explained that the clamping pipe 453 fixes the cross plate 451, and the cross plate 451 is used for compensating the V-shaped groove of the clamping table 42, so that the clamping table 42 can fix the component with a plane on the side, and the adaptability is strong.

[0035] As shown in Figure 4 , Figure 5 , the outer sides of the two vertical rods 452 are fixedly connected with spiral clamping strips 454, the inner sides of the clamping pipes 453 are slidably connected to the outer sides of the spiral clamping strips 454, and the front and back side protrusions of the clamping pipe 453 are slidably connected in the vertical grooves in the inner sides of the round holes.

[0036] It needs to be explained that rotating the spiral clamping strip 454 causes the spiral clamping strip 454 to drive the clamping pipe 453 to move up and down, thereby quickly installing and disassembling the cross plate 451.

[0037] As shown in Figure 4 , Figure 5 , the outer sides of the two vertical rods 452 are movably installed with second springs 455 close to the bottom positions.

[0038] It needs to be explained that the second spring 455 is a torsional spring, and in the initial state, the clamping pipe 453 is at the lowermost side, after rotating the vertical rod 452, the vertical rod 452 is released, and the second spring 455 can reset the vertical rod 452.

[0039] As shown in Figure 4 two clamping table 42 and two horizontal plate 451 away from the side of the spring 44 are fixedly connected with rubber pad.

[0040] It should be noted that the rubber pad to avoid clamping table 42 and horizontal plate 451 directly with the clamping component rigid contact, resulting in clamping table 42 and horizontal plate 451 to cause wear.

[0042] It should be noted that the limiting block 63 for the second clamping mechanism 7 bottom of the sliding connection in the T-shaped groove 62 inside the T-shaped block is limited, so that the second clamping mechanism 7 can't slide back on the connecting plate 61, and then make the second clamping mechanism 7 is fixed.

[0043] As shown in Figure 7 the rear side of the limiting block 63 is provided with friction.

[0044] It should be noted that the friction for increasing the friction between the hands of the limiting block 63, facilitate the user to push the limiting block 63 movement.
