[0022] The utility model provides an air leg 103 type crushing pneumatic pick device, including a holding component 101, a connecting component 102, an air leg 103 and a crushing component 104, the air leg 103 includes a mounting seat 105, a connecting block 106, a main leg 107 and an operating handle 108, the holding component 101 includes a holding rod 109, a top cap 110 and a threaded cap 111, the connecting component 102 includes a connecting tube 112, a threaded tube 113 and an anti-slip ring 114, and the crushing component 104 includes a crushing needle 115, a spring 116 and a limit ring 117.

[0023] According to this specific embodiment, the crushing assembly 104 is movably connected to the connecting assembly 102, the holding assembly 101 is movably connected to the connecting assembly 102, the operating handle 108 is fixedly connected to the main leg 107, one end of the main leg 107 is fixedly connected to the connecting block 106, the connecting block 106 is rotatably connected to the mounting seat 105, the mounting seat 105 is fixedly connected to the connecting assembly 102, the threaded cap 111 is fixedly connected to the top cap 110, the holding rod 109 is fixedly connected to the top cap 110, the anti-slip ring 114 is fixedly connected to the connecting cylinder 112, and the threaded cylinder 113 is fixedly connected to the connecting cylinder 112 is fixedly connected, the limit ring 117 is fixedly connected to the crushing needle 115, one end of the spring 116 is fixedly connected to the limit ring 117, the other end of the spring 116 is detachably connected to the connecting cylinder 112, the crushing needle 115 is movably connected to the connecting cylinder 112, and the main leg 107 currently set is connected to the connecting cylinder 112 through the connecting block 106 and the mounting seat 105, which can provide controllable propulsion force for the connecting cylinder 112, so as to facilitate the crushing work of the crushing needle 115. This design solves the problem that the propulsion pressure is difficult to control during the crushing process, and the crushing effect is easy to occur during crushing by adding the air leg 103.

[0024] Among them, the crushing component 104 is located below the connecting component 102, the holding component 101 is located above the connecting component 102, the operating handle 108 is located on one side of the main leg 107, one end of the main leg 107 is located on one side of the connecting block 106, the connecting block 106 is located on one side of the mounting seat 105, and the mounting seat 105 is located on one side of the connecting component 102. During use, the staff adjusts the deflection angle between the main leg 107 and the mounting seat 105 by operating the operating handle 108 to facilitate better work. When performing crushing work, the installed crushing needle 115 is directed to the location where crushing is required, and the holding rod 109 is held with both hands to perform vertical operations to achieve better crushing effects.

[0025] Secondly, the threaded cap 111 is located below the top cap 110, the holding rod 109 is located on one side of the top cap 110, the anti-slip ring 114 is located above the connecting tube 112, and the threaded tube 113 is located above the connecting tube 112. The threaded cap 111 and the threaded tube 113 can rotate with each other. The staff can fix the threaded cap 111 on the upper end of the threaded tube 113 or disassemble the threaded cap 111 by twisting the threaded cap 111, and the operation is convenient and quick. Due to the setting of the anti-slip ring 114, when twisting the threaded cap 111, the operator holds the anti-slip ring 114 with the other hand to ensure that it will not slip out of the hand during rotation, thereby avoiding accidental collision and injury to the operator's hand.

[0026] At the same time, the limiting ring 117 is located on the circumferential side of the breaker needle 115, one end of the spring 116 is located above the limiting ring 117, and the other end of the spring 116 is located at the lower end of the connecting tube 112. The breaker needle 115 is located below the connecting tube 112. The setting of the limiting ring 117 provides a limit for the installation of the breaker needle 115. When the staff rotates the spring 116 around the lower end of the connecting tube 112, as the spring 116 cannot rotate, the limiting ring 117 also reaches the tightest connection point. At the same time, in the process of rotating the spring 116, due to the setting of the limiting ring 117, the installation of the breaker needle 115 can be more stable and not easy to fall off from the lower end of the connecting tube 112.

[0027] In this embodiment, the main leg 107 is connected to the mounting seat 105 through the connecting block 106, which can provide a controllable propulsion force for the connecting cylinder 112, so that the crushing needle 115 can perform crushing work. This design solves the problem that the propulsion pressure in the crushing process is difficult to control and the crushing effect is easy to be poor during crushing by adding the air leg 103. During use, the staff adjusts the deflection angle between the main leg 107 and the mounting seat 105 by operating the operating handle 108 to facilitate better work. When performing the crushing work, the installed crushing needle 115 is directed to the location where crushing is required, and the holding rod 109 is held with both hands for vertical operation to achieve a better crushing effect. The staff screws the threaded cap 111 to facilitate the threaded cap 111 to be screwed. The cap 111 is fixed to the upper end of the threaded barrel 113 or the threaded cap 111 is disassembled, and the operation is convenient and quick. Due to the setting of the anti-slip ring 114, when the threaded cap 111 is twisted, the operator holds the anti-slip ring 114 with the other hand to ensure that it will not fall out of the hand during rotation, thereby avoiding accidental collision and injury to the operator's hand. The setting of the limit ring 117 provides a limit for the installation of the crushing needle 115. When the staff rotates the spring 116 around the lower end of the connecting barrel 112, as the spring 116 cannot rotate, the limit ring 117 also reaches the most tightly connected position. At the same time, in the process of rotating the spring 116, due to the setting of the limit ring 117, the installation of the crushing needle 115 can also be more stable and not easy to fall off from the lower end of the connecting barrel 112.
