The bottom plate 1 and the fixing block 9 are welded, and the supporting block 2 is welded to the bottom plate 1, so that the device is more stable. One side of the supporting block 2 is connected to one side of the fixing block 9. A slide groove 4 is opened on one side of the supporting block 2, and a clamping device 3 is arranged inside the slide groove 4.

[0035] The clamping device 3 includes a cylinder 12, a sliding rod 22 and a pad 11. The lower part of the cylinder 12 is fixedly connected to the pad 11, and the bottom end of the pad 11 is welded to the bottom plate 1. The output end of the cylinder 12 is fixedly connected to a pull plate 13. Two sliders 14 are arranged at both ends of the pull plate 13. A limiting strip 15 is arranged at the top of the slider 14. A limiting groove 23 is opened at the lower part of the sliding rod 22. The sliding rod 22 and the slider 14 are slidably connected through the limiting strip 15 and the limiting groove 23. The lower part of the sliding rod 22 and the upper part of the slider 14 are both inclined and parallel.

[0036] A clamping groove 5 is provided on the upper part of the support plate, and two clamping blocks 21 are respectively arranged on both sides of the clamping groove 5. Two sliding rods 22 are movably sleeved with the inner part of the support block 2. The upper parts of the two sliding rods 22 are respectively welded to the lower parts of the two clamping blocks 21. A fixing groove 24 is provided on the lower parts of the two clamping blocks 21. The nail magazine base can be placed in the two fixing grooves 24 and the clamping groove 5, and then the nail magazine base can be clamped.

[0037] A rectangular groove 8 is formed on the upper portion of the fixing block 9 , and a fixing device 7 is arranged inside the rectangular groove 8 .

[0038] The fixing device 7 includes a connecting block 32, a pressure rod 33, two rotating plates 31 and a push rod 35. The two sides of one end of the pressure rod 33 are rotatably connected to the inside of the connecting block 32, the two rotating plates 31 are rotatably connected to the two sides of the lower part of the pressure plate, and the two rotating plates 31 are rotatably connected to the push rod 35. A square groove 36 is opened on one side of the rectangular groove 8, and the square groove 36 is connected to the clamping groove 5. The push rod 35 is located inside the square groove 36 and the clamping groove 5. A rectangular block 34 is welded to the upper part of the push rod 35, and the upper part of the rectangular block 34 is fitted with the lower part of the pressure rod 33. The limiting blocks 6 are fixedly connected to the two sides of the clamping groove 5. By pressing the push rod 35, the push rod 35 can cooperate with the rectangular block 34 and the limiting blocks 6 to fix the base of the nail magazine.

[0039] Working principle: when the nail magazine base needs to be fixed, first pull the pull rod upward to reset the fixing device 7.
