[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0025] The embodiment of the present utility model discloses a portable switch machine handling device.

[0026] The present utility model provides a portable switch machine handling device as Figure 1-4 shown, which includes two support bottom plates 1. The two support bottom plates 1 are symmetrically arranged at the same horizontal level and there is a gap between the support bottom plates 1. Two connecting rods 2 are respectively fixedly connected to the upper surfaces of the two support bottom plates 1. Circular handles 3 are respectively fixedly connected to the tops of the plurality of connecting rods 2. Two limit screws 4 are respectively rotatably connected to the upper surfaces of the two support bottom plates 1. The cross-section of the two support bottom plates 1 is set in a U shape. Anti-slip patterns are provided on the side walls of the circular handles 3.

[0027] An adjusting mechanism is arranged at the gap on the corresponding side of the two support bottom plates 1. The adjusting mechanism includes a plurality of rectangular connecting cylinders 5 and two slide plates 6. The plurality of rectangular connecting cylinders 5 are arranged in pairs opposite to each other at the gap between the two support bottom plates 1. One end of the plurality of rectangular connecting cylinders 5 is fixedly connected to the side wall of the support bottom plate 1. The end of the plurality of rectangular connecting cylinders 5 away from the support bottom plate 1 is slidably sleeved with the slide plate 6.

[0028] During use, place the switch machine on the upper surface of the support base plate 1. Rotate the limit screw rod 4 so that the limit screw rod 4 extends into the positioning threaded hole of the switch machine, which can make the switch machine stably placed on the upper surface of the support base plate 1. The support base plate 1 is set in a U shape, which can improve the support strength. The sliding plate 6 slides along the inner wall of the rectangular connecting cylinder 5, which can flexibly adjust the gap between the two support base plates 1, can adapt to switch machines of different specifications, and can also reduce the placement volume for easy carrying. Lift the circular handle 3 to pull the connecting rod 2 to drive the support base plate 1 to rise, which is convenient for the staff to carry out handling. The side wall of the circular handle 3 is provided with anti-slip lines to prevent slipping during handling. This device is small in size, light in weight, convenient to carry, suitable for narrow spaces, and has sufficient hardness to effectively protect the handling operation.

[0029] In order to keep the sliding plate 6 stable inside the rectangular connecting cylinder 5, as Figure 1-4 shown, a limiting mechanism is provided inside the sliding plate 6. The limiting mechanism includes a partition plate 7, a resilient metal sheet 8, and a limiting block 9. A cavity is opened on the inner wall of the sliding plate 6. The partition plate 7 is fixedly connected to the inner wall of the cavity. The resilient metal sheet 8 is fixedly connected to the side wall of the partition plate 7. The limiting block 9 is fixedly connected to the end of the resilient metal sheet 8 facing away from the partition plate 7. A plurality of limiting holes are opened on the inner wall of the rectangular connecting cylinder 5. The limiting block 9 penetrates the cavity and extends to the inner wall of the limiting hole.

[0030] The resilient metal sheet 8 can push the limiting block 9 out of the sliding plate 6 and extend into the rectangular connecting cylinder 5 inside the limiting hole, which can make the sliding plate 6 stable inside the rectangular connecting cylinder 5, can ensure the stability during subsequent handling, and the rectangular connecting cylinder 5 and the sliding plate 6 can also support the switch machine, and can support and protect the bottom of the switch machine. Pressing the limiting block 9 to bend and compress the resilient metal sheet 8 can make the limiting block 9 contract into the cavity, which will not prevent the sliding plate 6 from moving and adjusting inside the rectangular connecting cylinder 5, and can ensure the adjustment of the distance between the two support base plates 1.

[0031] And in order to facilitate the adjustment process, as Figure 1-4 shown, a first chamfer is opened at one end of the limiting block 9 facing away from the resilient metal sheet 8. A second chamfer is opened on the inner wall of the rectangular connecting cylinder 5 at the limiting hole. A guiding groove is opened on the inner wall of the sliding plate 6 at the cavity. A guiding block 10 is slidably arranged on the inner wall of the guiding groove. The side wall of the guiding block 10 extends into the cavity and is fixedly connected to the side wall of the limiting block 9.

[0032] The first chamfer opened on the side wall of the limiting block 9 and the second chamfer opened on the inner wall of the rectangular connecting cylinder 5 at the limiting hole can make it easier for the limiting block 9 to contract into the cavity when being squeezed, which is convenient for the adjustment process. The guiding block 10 slides along the inner wall of the guiding groove, which can improve the sliding stability of the guiding block 10 during adjustment and movement.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
