Example

[0021] Please see Figure 1-5 The present invention provides the following technical solution: a handheld tobacco seedling punching device, including a handle 2, a hand protection component 1 is provided on the surface of one end of the handle 2, an installation shaft 7 is provided inside the other end of the handle 2, an intermediate block 6 is provided on one side of the installation shaft 7, a plurality of connecting frames 8 are provided on the surface of the intermediate block 6, an installation ring 5 is provided on the surface of the connecting frame 8, a positioning installation component 3 is provided inside the connecting frame 8, and a punching rod 4 is provided inside the positioning installation component 3.

[0022] Specifically, the positioning and installation component 3 includes a limiting baffle 31, a positioning rod 32, a guide rod 33, a limiting spring 34, a fixing device 35, a movable seat 37, and a movable plate 38. The connecting frame 8 has a movable seat 37 inside, a limiting baffle 31 on one side of the movable seat 37, a fixing device 35 on the other side of the movable seat 37, a guide rod 33 fixed inside the movable seat 37, a limiting spring 34 sleeved on the surface of the guide rod 33, a movable plate 38 at one end of the limiting spring 34, and positioning rods 32 symmetrically arranged on the surface of the movable plate 38.

[0023] By adopting the above technical solution, when the length of the punching rod 4 needs to be adjusted during use, the movable plate 38 is pulled along the guide rod 33 to compress the limiting spring 34. At this time, the positioning rod 32 disengages from the positioning hole inside the connecting frame 8. Then, the movable seat 37 inside the connecting frame 8 is slid to adjust the position of the punching rod 4. After determining the appropriate position, the movable plate 38 is released to reset the limiting spring 34. The positioning rod 32 is re-inserted into the connecting frame 8 to position the movable seat 37, ensuring the effectiveness of the punching rod 4 and ensuring the punching quality of the mulch film.

[0024] Specifically, the connecting frame 8 has several positioning holes corresponding to the positioning rod 32 inside, and the fixing device 35 has side baffles 36 symmetrically arranged on both sides.

[0025] By adopting the above technical solutions, the stability and accuracy of the positioning and installation of the movable seat 37 are ensured, thereby improving the quality of equipment use.

[0026] Specifically, the fixing device 35 includes a bearing 351, a clamping tooth block 352, a threaded rod 353, and a positioning seat 354. The positioning seat 354 is provided on one side of the movable seat 37, the clamping tooth block 352 is provided inside the positioning seat 354, the bearing 351 is provided on the surface of the clamping tooth block 352, and the threaded rod 353 is provided on one side of the bearing 351.

[0027] By adopting the above technical solution, when it is necessary to punch holes in the mulch film of flue-cured tobacco seedlings, a punching rod 4 of appropriate specifications can be selected for installation. Rotating the threaded rod 353 drives the clamping tooth block 352 to move along the inside of the positioning seat 354. Then, the punching rod 4 is inserted into the inside of the positioning seat 354, and the threaded rod 353 is reversed to push the clamping tooth block 352 to engage and fix the punching rod 4, ensuring the convenience and stability of the installation of the punching rod 4 and saving manpower.

[0028] Specifically, the two sides of the movable plate 38 are attached to the inner wall surface of the movable seat 37, and the two sides of the clamping tooth block 352 are attached to the inner wall surface of the positioning seat 354.

[0029] By adopting the above technical solution, the stability of the movement of the movable plate 38 and the clamping tooth block 352 is ensured, and deviation is prevented.

[0030] In this embodiment, when it is necessary to punch holes in the mulch film of flue-cured tobacco seedlings, a suitable punching rod 4 can be selected for installation. Rotating the threaded rod 353 drives the clamping tooth block 352 to move along the inside of the positioning seat 354. Then, the punching rod 4 is inserted into the inside of the positioning seat 354, and the threaded rod 353 is reversed to push the clamping tooth block 352 to engage and fix the punching rod 4, ensuring the convenience and stability of the installation of the punching rod 4 and saving manpower.

[0031] When the length of the punching rod 4 needs to be adjusted during use, the movable plate 38 is pulled along the guide rod 33 to compress the limiting spring 34. At this time, the positioning rod 32 disengages from the positioning hole inside the connecting frame 8. Then, the movable seat 37 slides along the inside of the connecting frame 8 to adjust the position of the punching rod 4. After determining the appropriate position, the movable plate 38 is released to reset the limiting spring 34. The positioning rod 32 is reinserted into the connecting frame 8 to position the movable seat 37, ensuring the effectiveness of the punching rod 4 and ensuring the punching quality of the mulch film. Example

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the hand protection component 1 includes a fixed circular plate 11, a protective shell 12, an anti-slip sleeve 13, and insulation cotton 14. The fixed circular plate 11 is fixed on the surface of the grip 2, the protective shell 12 is provided on one side of the fixed circular plate 11, the insulation cotton 14 is provided on the inner wall surface of the protective shell 12, and the anti-slip sleeve 13 is provided on one end surface of the grip 2 corresponding to the insulation cotton 14.

[0033] In this embodiment, when used in cold weather, the worker's hands can be inserted into the protective shell 12 to grip the anti-slip sleeve 13 to use the handle 2, which improves the stability of the handle 2. At the same time, the protective shell 12 can protect the hands from the wind and prevent frostbite. The insulation cotton 14 can prevent the hands from colliding with the inner wall of the protective shell 12 and also has a heat preservation effect, further improving the comfort of the worker's hands.

[0034] The working principle and usage process of this utility model: When it is necessary to punch holes in the mulch film of flue-cured tobacco seedlings, a suitable punching rod 4 can be selected for installation. Rotating the threaded rod 353 drives the clamping tooth block 352 to move along the inside of the positioning seat 354. Then, the punching rod 4 is inserted into the inside of the positioning seat 354, and the threaded rod 353 is reversed to push the clamping tooth block 352 to engage and fix the punching rod 4, ensuring the convenience and stability of the installation of the punching rod 4 and saving manpower.

[0035] When the length of the punching rod 4 needs to be adjusted during use, the movable plate 38 is pulled along the guide rod 33 to compress the limiting spring 34. At this time, the positioning rod 32 disengages from the positioning hole inside the connecting frame 8. Then, the movable seat 37 inside the connecting frame 8 is slid to adjust the position of the punching rod 4. After determining the appropriate position, the movable plate 38 is released to reset the limiting spring 34. The positioning rod 32 is reinserted into the connecting frame 8 to position the movable seat 37, ensuring the effectiveness of the punching rod 4 and ensuring the punching quality of the mulch film.

[0036] When used in cold weather, the staff can insert their hands into the protective shell 12 to grip the anti-slip sleeve 13 to use the handle 2, which improves the stability of the handle 2. At the same time, the protective shell 12 can protect the hands from the wind and prevent frostbite. The insulation cotton 14 can prevent the hands from hitting the inner wall of the protective shell 12 and also has a heat preservation effect, further improving the comfort of the staff's hands.
