The connecting blocks 35 are slidably connected to the first guide rod 32. The guide blocks 33 are connected between the lower parts of the four first guide rods. The guide blocks 33 are used to position the sleeve of the blind rivet 1 so that it can be inserted into the hole of the connecting piece. The first compression spring 34 is connected between the connecting blocks 35 and the guide blocks 33. The first compression spring 34 is sleeved on the first guide rod 32.

[0037] When in use, the nail core of the blind rivet 1 is inserted into the clamping column 12, and then the guide block 33 is pressed against the connecting piece, and the guide block 33 is used for positioning so that the sleeve of the blind rivet 1 is aligned with the hole of the connecting piece, and then the mounting plate frame 11 is manually pressed downward, and the mounting plate frame 11 drives the clamping column 12, the blind rivet 1, the turntable 31 and the connecting block 35 to move downward, and the first compression spring 34 is compressed, so that the sleeve of the blind rivet 1 is accurately inserted into the hole of the connecting piece, and then the telescopic handle 21 is manually squeezed inward, and the telescopic handle 21 drives the clamping column 12 to move upward and retract into the mounting plate frame 11 through the first swing rod 23, and the tension spring 22 is stretched, so that the mounting plate frame 11 presses the clamping column 12, so that the clamping column 12 clamps the nail core and pulls the nail core upward until the lower part of the sleeve expands and is fastened to the connecting piece. The riveting is completed until the nail core is broken and pulled out, the mounting plate frame 11 is loosened, and then the mounting plate frame 11 is driven to move upward and reset through the turntable 31 and the connecting block 35 under the action of the first compression spring 34 resetting, and then the telescopic handle 21 is loosened, and then the clamping column 12 is driven to move downward and reset under the action of the tension spring 22 resetting, and the clamping column 12 drives the telescopic handle 21 to rotate outward and reset through the first swing rod 23, and then the nail core is taken out from the clamping column 12. When not in use, the guide block 33 is manually rotated upward, and the guide block 33 drives the turntable 31, the first guide rod 32, the first compression spring 34 and the connecting block 35 to rotate upward and retract, and then the telescopic handle 21 is manually retracted downward, and then the telescopic handle 21 is manually squeezed inward, and the telescopic handle 21 is clamped on the rubber clamp of the mounting plate frame 11 for retraction, so that the occupied area can be reduced. Example 2

[0038] Based on Example 1, Figure 1 , Figure 2 , Fig. 9 and Fig.10, also includes a pushing mechanism 4, the pushing mechanism 4 includes a top block 41, a first slide rod 42 and a second compression spring 43, two first slide rods 42 are welded to the lower part of the mounting plate frame 11, and a top block 41 is slidably connected between the two first slide rods 42. The top block 41 is used to eject the nail core. The top block 41 passes through the clamping column 12. Two second compression springs 43 are connected between the top block 41 and the mounting plate frame 11, and the second compression spring 43 is sleeved on the first slide rod 42.

[0039] When the nail core of the blind rivet 1 is inserted into the clamping column 12, the nail core contacts the top block 41, thereby pushing the top block 41 to move upward, and the second compression spring 43 is compressed. When the clamping column 12 pulls the nail core upward, the nail core continues to push the top block 41 to move upward. After the nail core is pulled out of the sleeve, when the clamping column 12 moves downward to reset, the clamping column 12 drives the nail core to move downward to reset. At the same time, under the action of the reset of the second compression spring 43, the top block 41 is driven to move downward to reset, and the top block 41 pushes the nail core downward, so that there is no need to manually remove the nail core from the clamping column 12.

[0040] Reference Figure 1 , Figure 2 , Fig.11 and Fig.12 , also includes a pushing mechanism 5, the pushing mechanism 5 includes a support frame 51, a second guide rod 52, a placement box 53, a guide frame 54, a first spring 55, a second slide bar 56, a limit frame 57, a second spring 58, a movable plate 59, a second swing rod 510 and a limit column 511, the support frame 51 is installed on the right side of the guide block 33, the front and rear sides of the top of the guide block 33 are connected to two second guide rods 52, the front and rear sides of the middle of the support frame 51 are slidably connected to the guide frame 54, the guide frame 54 is connected to the support frame 51 with two first springs 55, the first spring 55 is sleeved on the guide frame 54, the two guide frames 54 A placement box 53 is installed in between, and second sliding rods 56 are slidably connected to the front and rear sides of the upper part of the support frame 51. A limiting frame 57 is welded between the right ends of the two second sliding rods 56, and the limiting frame 57 has a blocking effect. A second spring 58 is connected between the right part of the second sliding rod 56 and the support frame 51, and the second spring 58 is sleeved on the second sliding rod 56. A moving plate 59 is slidably connected between the two second guide rods 52 on the front and rear sides, and two second swing rods 510 are rotatably connected between the moving plate 59 and the placement box 53. Three limiting columns 511 are connected to the front and rear sides of the left part of the placement box 53, and the limiting columns 511 have a blocking effect.

[0041] The blind rivets 1 are arranged horizontally from right to left and placed in the placement box 53. When the mounting plate frame 11 drives the clamping column 12 to move downward, the clamping column 12 contacts the nail core of the blind rivet 1 directly below it, so that the upper part of the nail core of the blind rivet 1 is inserted into the clamping column 12. At the same time, the mounting plate frame 11 moves downward and contacts the movable plate 59, and then presses the movable plate 59 downward. The movable plate 59 pushes the placement box 53 to move right through the second swing rod 510. The placement box 53 drives the guide frame 54, the limiting column 511 and the remaining blind rivets 1 to move right. The first spring 55 is compressed, so that the blind rivet 1 stuck by the clamping column 12 is separated from the placement box 53, and then the clamping column 12 drives the blind rivet 1 to move downward to insert the sleeve into the hole of the connecting piece. When the rightmost blind rivet 1 contacts the limiting frame 57, the limiting frame 57 intercepts the blind rivet 1 in the placement box 53 and the placement box 53. The boxes 53 move opposite to each other. When the leftmost blind rivet 1 contacts the limiting column 511, the limiting column 511 limits the blind rivet 1, so that when the placement box 53 drives the limiting column 511 to move to the right, the limiting column 511 pushes the limiting frame 57 to move to the right through the blind rivet 1, and the limiting frame 57 drives the second slide bar 56 to move to the right, and the second spring 58 is compressed. When the mounting plate frame 11 moves upward and resets, the placement box 53 and the limiting column 511 are driven to move to the right and reset through the guide frame 54 under the action of the first spring 55 reset. The placement box 53 drives the moving plate 59 to move upward and reset through the second rocker rod 510. The placement box 53 drives the blind rivet 1 to move to the left, so that the blind rivet 1 on the left is located directly under the clamping column 12. At the same time, the second slide bar 56 and the limiting frame 57 are driven to move to the left and reset under the action of the second spring 58 reset. In this way, automatic material replenishment is achieved.

The first air cylinder 61 is installed on both sides of the front and rear of the right part of the placement box 53, and push blocks 62 are welded on both sides of the front and rear of the upper part of the support frame 51. The third spring 63 is connected between the first air cylinder 61 and the piston rod of the first air cylinder 61. Two guide rails 66 are installed on the left side of the top of the placement box 53, and the second air cylinder 65 is slidably connected on the guide rails 66. The air guide tube 64 is connected between the second air cylinder 65 on the front side and the first air cylinder 61 on the front side, and the air guide tube 64 is connected between the second air cylinder 65 on the rear side and the first air cylinder 61 on the rear side.

When the blind rivet 1 and the placement box 53 move in opposite directions, the leftmost blind rivet moves to the left between the clamping block 68. When the placement box 53 moves to the left to reset, the placement box 53 drives the first air cylinder 61, the third spring 63, the air guide tube 64, the second air cylinder 65, the guide rail 66, the telescopic assembly 67 and the clamping block 68 to move to the left to reset. When the piston rod of the first air cylinder 61 contacts the push block 62, the piston rod of the first air cylinder 61 contracts to inflate the second air cylinder 65, and the third spring 63 is compressed. , so that the piston rod of the second gas cylinder 65 is extended to drive the clamping block 68 to move inward to clamp the core-pulling rivet, so as to prevent the core-pulling rivet located directly below the clamping column 12 from being displaced, resulting in the core-pulling rivet not being aligned with the clamping column 12. When the clamping column 12 clamps the upper part of the rivet core of the core-pulling rivet 1, the placement box 53 moves to the right, and the placement box 53 drives the first gas cylinder 61, the third spring 63, the air guide tube 64 and the guide rail 66 to move to the right, and the telescopic assembly 67 contracts, and the piston rod of the first gas cylinder 61 is separated from the push block 62, and then the first gas cylinder 61 is pushed into the air cylinder 61. The three springs 63 are reset to move the piston rod of the first gas cylinder 61 out to extract the gas in the second gas cylinder 65, so that the piston rod of the second gas cylinder 65 contracts to drive the clamping block 68 to move outward to loosen the blind rivet, and then the telescopic assembly 67 is reset to move the second gas cylinder 65 and the clamping block 68 to the right to reset. In this way, when the clamping column 12 clamps the blind rivet 1, the placement box 53 is prevented from moving to the right to directly pull the blind rivet 1 to the right through the clamping block 68, causing the blind rivet 1 to detach from the clamping column 12.

[0045] The connecting plate 71 is removed from the placement box 53, the top plate 72 is separated from the placement box 53, and then the blind rivets 1 are arranged horizontally from right to left and placed in the placement box 53, and then the connecting plate 71 and the top plate 72 are reset. When the top plate 72 contacts the rightmost blind rivet 1, the third compression spring 73 is compressed, and the connecting plate 71 is installed on the placement box 53. When the leftmost blind rivet 1 is separated from the placement box 53, the top plate 72 pushes the remaining blind rivets 1 to move to the left under the action of the third compression spring 73. In this way, auxiliary material replenishment is achieved, and the blind rivets 1 in the placement box 53 are limited to prevent the blind rivets 1 in the placement box 53 from being displaced.
