Description

Technical Field

[0001] The utility model belongs to the field of large-fruit hazelnut seedling cultivation, and specifically relates to a C-shaped pneumatic nail gun for large-fruit hazelnut seedling cultivation. Background Art

[0002] The large-fruited hazelnut tree is a deciduous shrub also known as the "King of Nuts." Scientifically known as Corylus australis, it is a superior variety bred through interspecific hybridization and suitable for cultivation in northern China. This hazelnut tree features large fruits, high yields, strong ecological adaptability, and tolerance to cold, drought, salinity, and infertility. It is also relatively pest- and disease-resistant, simple to manage, and has low investment costs. However, during the seedling cultivation period, the roots and trunks of large-fruited hazelnut trees require tying and binding.

[0003] Chinese patent publication number CN213647422U discloses a C-type pneumatic nail gun comprising a housing, an air valve disposed within the housing, a piston shaft disposed within the air valve, a fixing member connected to the housing, a switch ejector pin connected to the piston shaft, a switch guide sleeve mounted on the switch ejector pin, a trigger for driving the switch ejector pin, and a striker assembly connected to the housing. The air valve comprises an air valve body, an air hole disposed on the air valve body, and an air seal ring mounted on the air valve body, the air hole and the air seal ring being spaced apart. The piston shaft reciprocates within the air valve and comprises a piston shaft body, a piston shaft air hole disposed on the piston shaft body, and a cavity within the piston shaft, the piston shaft air hole communicating with the cavity. The C-type pneumatic nail gun provided by this utility model is responsive, reduces fatigue from long-term use, and saves time and effort.

[0004] However, pneumatic nail guns need to be inflated to start, and the connection between the inflation tube and the nail gun becomes loose, causing air leakage. In addition, the connection between the nail gun and the air tube lacks protection. When the nail gun is used, the connection between the air tube and the nail gun will inevitably bend, which will eventually cause the air tube to rupture.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a C-type pneumatic nail gun for growing large-fruit hazelnut seedlings, which solves the problem that the pneumatic nail gun proposed in the above background technology needs to be inflated to start, and the connection between the inflation tube and the nail gun becomes loose, causing air leakage, and the connection between the nail gun and the air pipe lacks protection. When the nail gun is used, it is bound to cause the connection between the air pipe and the nail gun to bend, which will cause the air pipe to rupture over time.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A C-type pneumatic nail gun for growing large-fruit hazelnut seedlings comprises: a cylinder body, a cylinder rod is provided at one end of the cylinder body, a nail gun clamp is provided at one end of the cylinder rod, a roller is provided on the surface of the nail gun clamp, a handle is provided at the bottom of the cylinder body, a connecting head for inflation is provided at the bottom of the handle, a connecting assembly for improving air tightness and quick disassembly is provided at the bottom of the connecting head, and a protective assembly for improving protectiveness is provided at the bottom of the connecting assembly.

[0009] Optionally, the connecting assembly includes a connecting tube arranged at the bottom of the connecting head, and a plurality of first springs are arranged on the surface of the bottom of the connecting tube in a circular array, and a triangular plate is arranged on the side of the first spring, and the interior of the triangular plate is movably connected to a positioning plate, and the surface of one end of the positioning plate is fixedly connected to one end of the first spring, and the surface of the other end of the positioning plate is provided with a barb.

[0010] Optionally, a sleeve is inserted into the bottom end of the connecting tube, a limiting ring is provided at the top end of the sleeve, and the limiting ring is engaged with the surface of the barb, and a flexible sealing ring is provided on the inner wall of the sleeve to increase the sealing performance.

[0011] Optionally, a rotary joint is provided at the bottom of the sleeve, and an inflation tube for inflation is provided at the bottom of the rotary joint.

[0012] Optionally, the protective component includes a rubber tube arranged on the bottom surface of the sleeve, a cavity is opened inside the rubber tube, and a second spring for buffering is arranged inside the cavity.

[0013] Optionally, a baffle is fixedly connected to one end of the cylinder body and on both sides of the cylinder rod, and a clamping plate is provided on the inner wall of the baffle, and the bottom of one end of the clamping plate is slidably connected to the surface of the roller.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0015] 1. Through the arrangement of the connecting component and the protective component, when using the nail gun, the sleeve at one end of the inflatable tube is inserted into the bottom of the connecting tube. As the sleeve is inserted, the limiting ring squeezes the barb, and the barb drives the positioning plate to compress the first spring. When the sleeve is fully inserted into the bottom of the connecting tube, the limiting ring is located at the top of the barb, and the positioning plate is acted upon by the elastic force of the first spring, driving the positioning plate and the barb to rebound and hook the limiting ring, thereby completing the fixation. At the same time, the flexible sealing ring arranged inside the sleeve improves the connection firmness and the air tightness of the connection when it is continuously inserted into the bottom of the connecting tube. At the same time, when using the nail gun, since a rubber tube is arranged at the bottom of the sleeve and a second spring is arranged inside the rubber tube, as the nail gun is used and moved, the inflatable tube at the bottom of the nail gun can be prevented from excessive bending, thereby improving the protectiveness of the inflatable tube.

[0032] In this embodiment, if Figure 3 As shown, the connecting assembly 7 includes a connecting tube 71 arranged at the bottom of the connecting head 6, and the surface of the bottom of the connecting tube 71 is provided with a plurality of first springs 72 in an annular array, and a triangular plate 73 is provided on the side of the first spring 72, and the interior of the triangular plate 73 is movably connected to a positioning plate 74, and the surface of one end of the positioning plate 74 is fixedly connected to one end of the first spring 72, and the surface of the other end of the positioning plate 74 is provided with a barb 75, and the bottom end of the connecting tube 71 is plugged with a sleeve 711, and the top end of the sleeve 711 is provided with a limiting ring 712, and the limiting ring 712 is clamped with the surface of the barb 75, and the inner wall of the sleeve 711 is provided with a flexible sealing ring 713 for increasing the sealing performance. When the bolt 711 is in the closed position, the locking nut 770 is in the closed position, and the spring 770 is in the closed position, so that the bolt 711 can be locked.

[0033] Example 2:

[0034] In this embodiment, if Figure 4 As shown, the protective component 8 includes a rubber tube 81 arranged on the bottom surface of the sleeve 711, a cavity is opened inside the rubber tube 81, and a second spring 82 for buffering is arranged inside the cavity. When using the nail gun, since the rubber tube 81 is arranged at the bottom of the sleeve 711 and the second spring 82 is arranged inside the rubber tube 81, as the nail gun is used and moved, the inflation tube 10 at the bottom of the nail gun can be prevented from being excessively bent, thereby improving the protective performance of the inflation tube 10.
