[0020] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0022] See also Figure 1-Figure 4 , This embodiment provides an easy-to-use pneumatic pick, including a pneumatic pick body 1, which is composed of an impact mechanism, an air distribution mechanism, a pick drill and other components. When in operation, the impact hammer repeatedly moves and strikes along a cylinder in the impact mechanism, and the pick drill can achieve the purpose of crushing on the construction surface. It is a prior art. A handle 2 is fixedly connected to the top of the pneumatic pick body 1, and an air inlet 3 is provided on the right side of the pneumatic pick body 1. The air inlet 3 is a part of the structure of the pneumatic pick body 1, and is used to deliver compressed air into the pneumatic pick body 1 so that the piston repeatedly strikes the pick head to open mountains, build roads and mine. A handle assembly 4 is provided on the left side of the pneumatic pick body 1, and the handle assembly 4 includes two support plates 401. The number of the support plates 401 is two, and the two support plates 401 are fixedly connected to the left side of the pneumatic pick body 1. The two support plates 401 are The surface is penetrated and rotatably connected with a rotating column 402, a bearing is provided between the rotating column 402 and the two support plates 401, and a handle 403 is fixedly connected to the outer surface of the rotating column 402, and a screw 404 is threaded through the left side of the handle 403, and an end is provided at the left end of the screw 404. When the screw 404 is inserted into the threaded hole 405, the end will fit with the handle 403, and a threaded hole 405 is provided on the left side of the pneumatic pick body 1, and the threaded hole 405 is adapted to the screw 404, and the screw 404 can be inserted into the threaded hole 405. The handle assembly 4 also includes a limiting rod 406, which is fixedly connected between the two support plates 401. When the rotating column 402 rotates to drive the handle 403 to flip upward until it rests against the limiting rod 406, the position of the screw 404 will correspond to the threaded hole 405.

[0023] When the above-mentioned device is used, a handle 403 is provided on the pneumatic pick body 1 to facilitate the user to operate the pneumatic pick body 1 better. When the handle 403 needs to be used, the handle 403 is lifted up until it is against the limit rod 406. At this time, the position of the screw 404 on the handle 403 will correspond to the threaded hole 405. The screw 404 on the handle 403 is rotated to move it to the right until the screw 404 is inserted into the threaded hole 405. At this time, the upper end of the screw 404 will fit with the handle 403, and the handle 403 is fixed on the pneumatic pick body 1 for easy operation of the pneumatic pick body 1. When the handle 403 needs to be put away, the screw 404 is rotated to pull it out of the threaded hole 405. At this time, the handle 403 can be flipped down. By flipping the handle 403 down to droop, it is not necessary to take up extra space. Example

[0024] See also Figure 1-Figure 4 On the basis of the first embodiment, a protective component 5 is provided on the outer surface of the pneumatic pick body 1, and the protective component 5 includes a second metal strip 501, the second metal strip 501 is hinged to the outer surface of the pneumatic pick body 1, a first metal strip 502 is hinged above the second metal strip 501, the lower end of the first metal strip 502 is hinged to the middle position of the second metal strip 501, and a connecting component 6 is provided above the first metal strip 502. The number of the second metal strips 501 and the first metal strips 502 is six, and the material of the second metal strips 501 and the first metal strips 502 is stainless steel. The connecting component 6 includes a sliding ring 601, and the sliding ring 601 is connected to the pneumatic pick body The outer surface of the body 1 is slidably connected, and the sliding ring 601 is sleeved on the outer surface of the pneumatic pick body 1 and can slide up and down. The sliding ring 601 is hinged to the upper end of the first metal bar 502, and the hinge is located below the sliding ring 601. A connecting bar 602 is hinged above the sliding ring 601, and a connecting piece 604 is rotatably connected to the upper part of the connecting bar 602 through a rotating shaft 603. The connecting piece 604 has a zigzag structure, and the connecting piece 604 is fixedly connected to the front end of the rotating column 402. The protective component 5 also includes a protective film 503. The material of the protective film 503 is a polyurethane film. The protective film 503 is fixedly connected between two adjacent second metal bars 501.

[0025] When the above device is used, the handle 403 will drive the rotating column 402 to rotate in the two supporting plates 401 when it is flipped, and the rotation of the rotating column 402 will drive the connecting plate 604 to rotate. When the handle 403 is flipped upward, the rotating column 402 will rotate clockwise, and the clockwise rotation of the rotating column 402 will drive the connecting plate 604 to flip downward. The connecting plate 604 will drive the connecting strip 602 to make the sliding ring 601 slide down on the outer surface of the pneumatic pick body 1, and the sliding ring 601 will Push the first metal bar 502 to prop up the second metal bar 501, so that the protective film 503 is opened, thereby preventing debris from flying upwards. When the handle 403 is flipped downward, the rotating column 402 will rotate counterclockwise, the connecting piece 604 will flip upward and then pull the connecting bar 602 to make the sliding ring 601 rise on the outer surface of the pneumatic pick body 1. The sliding ring 601 will pull the first metal bar 502 to lift the second metal bar 501. At this time, the protective film 503 will be retracted, thereby reducing the occupied space.
