[0022] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0023] like Figure 1-2 As shown, the utility model is a focusing device for an engraving machine, comprising a carrier platform 1, an engraving machine body 2 (the engraving machine is a prior art and will not be described in detail here), a driving mechanism and two adjusting components; the engraving machine body 2 is located at the top of the carrier platform 1, and a accommodating cavity 11 is opened in the carrier platform 1, and support columns are installed at the four corners of the bottom end of the carrier platform 1; the two adjusting components are both arranged in the accommodating cavity 11, and the top ends of the adjusting components pass through the accommodating cavity 11 and extend to the outside of the carrier platform 1, and the end of the adjusting component located outside the carrier platform 1 is connected to the engraving machine body 2, and the adjusting component is used to drive the engraving machine body 2 to move in the vertical direction of the carrier platform 1; the driving mechanism is arranged in the accommodating cavity 11, and the driving mechanism is used to drive the adjusting component to rotate, so as to drive the engraving machine body 2 to move.

[0024] By coordinating the support platform 1, the engraving machine body 2, the driving mechanism and a plurality of adjusting components, the driving mechanism can drive the adjusting components to adjust the focal length of the engraving machine body 2, thereby improving work efficiency and facilitating the user to mark the product.

[0025] In some embodiments, the adjustment assembly includes a rotating shaft 31 and an adjustment rod 32. The bottom end of the rotating shaft 31 is rotatably mounted in the accommodating cavity 11, and the rotating shaft 31 is arranged in cooperation with the driving mechanism. The outer side of the rotating shaft 31 is connected to the adjustment rod 32 through a thread. The top end of the adjustment rod 32 is located outside the carrier 1 and is connected to the bottom end of the marking machine body 2. The rotation of the rotating shaft 31 drives the adjustment rod 32 to move, and drives the marking machine body 2 to move, thereby adjusting the focal length of the marking machine body 2.

[0026] In some embodiments, a limiting strip 41 is symmetrically installed at one end of the adjusting rod 32 close to the rotating shaft 31, and a limiting groove 42 is symmetrically provided in the accommodating cavity 11, and the limiting strip 41 is slidably installed in the limiting groove 42. When the adjusting rod 32 moves, the limiting strip 41 is driven to slide in the limiting groove 42. Due to the restriction of the limiting groove 42, the adjusting rod 32 can only slide up and down, which is conducive to improving the sliding effect of the adjusting rod 32; at the same time, the limiting strip 41 and the limiting groove 42 can also limit the sliding distance of the adjusting rod 32.

[0027] In some embodiments, the driving mechanism includes a driving assembly and a transmission rod 51, the driving assembly is arranged in cooperation with the middle of the transmission rod 51, support rods are symmetrically installed in the accommodating cavity 11, the left and right ends of the transmission rod 51 respectively penetrate the middle of the two support rods, and the left and right ends of the transmission rod 51 are both installed with first transmission gears 52, and the outer bottom ends of the two rotating shafts 31 are both installed with second transmission gears 53, and the second transmission gears 53 are meshed with the first transmission gears 52. The driving assembly drives the transmission rod 51 to rotate, thereby synchronously driving the two second transmission gears 53 to rotate through the two first transmission gears 52, and then driving the two rotating shafts 31 to rotate at the same time, which is conducive to driving the two adjustment rods 32 to move synchronously, so as to facilitate the adjustment of the focal length of the engraving machine body 2.

[0028] In some embodiments, the driving assembly includes a driving rod 61 and a driving motor 62. The driving rod 61 is rotatably installed in the accommodating cavity 11, and the rear end of the driving rod 61 passes through the accommodating cavity 11 and emerges from the supporting platform 1. The side of the driving rod 61 located outside the supporting platform 1 is fixedly connected to the output shaft of the driving motor 62. The driving motor 62 is installed at the rear end of the supporting platform 1. The end of the driving rod 61 located in the accommodating cavity 11 is installed with a first driving gear 63, and the middle part of the transmission rod 51 is installed with a second driving gear 64, and the second driving gear 64 is meshed with the first driving gear 63. When the driving motor 62 is started, the output shaft of the driving motor 62 drives the driving rod 61 to rotate, thereby driving the first driving gear 63 and the second driving gear 64 to rotate, and then driving the transmission rod 51 to rotate, which is conducive to improving work efficiency.

[0029] In some embodiments, scale lines (not shown) are provided on the outer sides of the upper ends of the two adjustment rods 32 to facilitate the user to observe through the scale lines.

[0030] The method of using the utility model is as follows:

[0031] The user starts the drive motor 62, and the output shaft of the drive motor 62 drives the drive rod 61 to rotate, thereby driving the first drive gear 63 and the second drive gear 64 to rotate, and drives the transmission rod 51 to rotate, so that the two second transmission gears 53 are synchronously driven to rotate through the two first transmission gears 52, and then the two rotating shafts 31 are driven to rotate at the same time, which is conducive to driving the two adjustment rods 32 to slide synchronously, and then adjusting the distance between the engraving machine body 2 and the support platform 1, so as to achieve the effect of facilitating the adjustment of the focal length.
