The fuse box 9 is provided with a first telescopic rod 11, and the first telescopic rod 11 is tightly arranged against the top end of the fuse box 9. The outer side of the first telescopic rod 11 is sleeved with a second spring 12, and the other end of the first telescopic rod 11 is tightly arranged with a feeler 23, and the bottom end of the feeler 23 is fixedly connected to a rotating frame 13. A rotating pin 24 is provided inside the rotating frame 13, and a rotating block 17 is sleeved on the outer side of the rotating pin 24. The bottom end of the rotating block 17 is fixedly connected to the second telescopic rod 25, and a hole is opened in the second telescopic rod 25. The rotating pin 24 slides inside the second telescopic rod 25, and a third spring 26 is sleeved on the outer side of the second telescopic rod 25. The bottom end of the third spring 26 is tightly arranged against the sliding block 16, and the bottom end of the sliding block 16 is tightly arranged against the special-shaped block 14. The right side of the special-shaped block 14 is fixedly connected with an extension column 15, and the right side of the extension column 15 is tightly against the interior of the fuse box 9.

[0028] In this embodiment, the second spring 12 presses down the feeler 23 at the top of the rotating frame 13, and the sliding block 16 touches the extension column 15. When the welding machine 21 fails, the external security system 18 can realize the function of rapid power off, which facilitates the operation of the welding machine 21 in a more complex environment.

[0029] Example 2

[0030] like Figures 3 to 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a slide groove is provided at the top of the protection track 1, a baffle 3 is fixedly connected to the left side of the slide groove of the protection track 1, a partition 5 is fixedly connected to the right side of the baffle 3, a first spring 6 is sleeved on the right side of the partition 5, a movable plate 4 is tightly arranged on the right side of the first spring 6, a circular hole is provided inside the movable plate 4, a central shaft 7 is slidably connected to the circular hole of the movable plate 4, a fixing pin 20 is fixedly connected to the rear side of the central shaft 7, a slider 19 is slidably provided inside the protection track 1, a support block 2 is sleeved on the outer side of the slider 19, and the support block 2 The bottom end fits with the top of the protection track 1, the support block 2 slides on the top of the protection track 1, the top of the support block 2 is fixedly connected to the transport platform 8, the top of the transport platform 8 is fixedly connected to the latch seat 22, the inside of the latch seat 22 is sleeved with a connecting rod 10, the left side of the connecting rod 10 is fixedly connected to the fuse box 9, the top of the fuse box 9 is fixedly connected to the security system 18, the top of the security system 18 is fixedly connected to the latch seat 22, the top of the latch seat 22 is fixedly connected to the welding machine 21, the partition 5 and the first spring 6 on the outside of the movable plate 4 are arranged into two groups, and are respectively fixed on the outside of the movable plate 4.

[0031] In this embodiment, the transport platform 8 moves to the right, and the partition 5 hits the left side of the slide groove of the protective track 1, which is fixedly connected to a baffle 3 to achieve shock absorption, thereby achieving buffering. In a complex environment, it avoids damage to internal components caused by heavy pressure and collision, thereby improving the practicality of the transport platform 8.

[0032] The working principle of this utility model:

[0033] First, the staff places the protection track 1 on the flat ground, inserts the transport platform 8 on the top of the support block 2, and fixes it. The slider 19 slides inside the protection track 1 to push the transport platform 8 to the working position, inserts the connecting rod 10 on the outside of the fuse box 9 into the pin seat 22 on the top of the transport platform 8, and fixes the security system 18 on the top of the fuse box 9. Turn on the motor, and the transport platform 8 drives the welder 21 to move and realize the cutting function.

[0034] When the welder 21 fails, the security system 18 squeezes the first telescopic rod 11 downward in a short time. At this time, the first telescopic rod 11 squeezes the feeler 23 to move to the right. The feeler 23 is fixedly connected to the first telescopic rod 11, and the rotating pin 24 inside the rotating frame 13 squeezes the second telescopic rod 25 downward. At this time, the rotating pin 24 slides inside the second telescopic rod 25, and the second telescopic rod 25 deviates to the right. The second telescopic rod 25 drives the sliding block 16 to deviate to the left. At this time, the sliding block 16 is in close contact with the special-shaped block 14, and the special-shaped block 14 deviates to the left and touches the switch. At this time, a short circuit occurs, and power-off protection is achieved, thereby limiting the operation of the welder 21.

[0035] When the slider 19 at the bottom end of the support block 2 drives the transport platform 8 to move, when the support block 2 touches the partition 5, it pushes the partition 5 to slide toward the baffle 3 inside the protection track 1. When the partition 5 and the baffle 3 are pressed tightly, the transport platform 8 is still offset to the left. At this time, the central axis 7 inside the moving plate 4 slides to the left, thereby reducing the impact force, and the first spring 6 on the outside of the partition 5 cushions the moving plate 4, thereby ensuring that the moving plate 4 slides inside the protection track 1, which is safer during the sliding process.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
