Description

Disassembly air tools

The present invention relates to a pneumatic tool, in particular to a disassembly pneumatic tool for disassembling a grease nozzle.

According to the Republic of China's new patent No. M455067, it discloses an improved structure of a nozzle puller, wherein the puller has a pull assembly and a sleeve; the sleeve is connected to the nozzle, and the sleeve can be connected and assembled with the pull assembly; the pull assembly has a connecting rod and a gripping barrel sleeved on the outside of the connecting rod, wherein when the user holds the gripping barrel and pulls it upward, the inner wall of the gripping barrel abuts against the expanded diameter of the connecting rod, thereby driving the sleeve to pull out the nozzle.

However, the aforementioned method requires manual labor to pull the handle barrel in order to remove the nozzle, which is time-consuming and labor-intensive to use.

Moreover, the aforementioned extractor is fixed in shape and cannot be adjusted according to the size of the disassembly space. As a result, the user must adjust the connection position of the extractor and the oil nozzle according to the size of the disassembly space. If the adjustment angle is too large, the extractor may not be completely connected to the oil nozzle, resulting in the separation of the extractor and the oil nozzle when the oil nozzle is pulled, so that the oil nozzle cannot be disassembled smoothly, causing inconvenience during use.

In order to solve the above problems, the present invention provides a pneumatic disassembly tool that can generate vibration force in a pneumatic manner to achieve the function and purpose of vibration disassembly of the oil nozzle; and the connecting parts are covered with a kit to avoid the problem of air leakage caused by the vibration force of the actuator.

In one embodiment, an air groove is formed around the outer periphery of the second connecting portion, and the second air channel is opened in the air groove and connected to the channel.

In one embodiment, the channel is opened from the outer periphery of the kit, and the setting direction of the sleeve hole is perpendicular to the setting direction of the channel.

In one embodiment, the setting direction of the sleeve hole is perpendicular to the setting direction of the channel; a grip portion extends outward from the outer periphery of the sleeve, and a flow channel is opened in the grip portion, the flow channel is connected to the channel, and one end of the flow channel is screwed to the air source.

Please refer to Figures 13 and 14. When another embodiment of the present invention is used (for inflation), since the air source P is directly screwed to the channel 22 of the kit 20, the gas from the air source P will directly enter the air groove 123 of the connecting member 10, and pass through the second air channel 14 of the connecting member 10, the first air channel 13, the air hole 31 of the first fixing member 30 and the second plug hole 51 of the second fixing member 50, and then be introduced into the space between the second fixing member 50 and the barrel 72; accordingly, under the continuous input of gas, the actuator 70 repeatedly vibrates and displaces, so as to facilitate the application of vibration force to the oil nozzle F, so as to achieve the purpose of disassembling the oil nozzle F.
