Embodiment Construction
[0013] In the present invention, a scale is engraved on the sliding rod of the control device, which is accurate to millimeter, and a hoop clip is provided, and the fixing and moving of the hoop clip are realized by adjusting the degree of tightness. When the fixed hollow rod on the outside of the slide bar encounters the hoop clamp, the percussion drill bit will stop moving forward, so the depth of each powder extraction can be controlled by setting the position of the hoop clamp. The dust collector mainly includes a powder collection cylinder and a powder collection bottle. The powder collection cylinder seals the dust drilled by the drill bit in a relatively closed space, and collects the dust into a detachable powder collection bottle through the action of its own weight and the shaking of the device. . In order to closely and vertically stick the powder collection tube to the surface of the structure, a spring is provided at the end of the slide bar near the drilling mach...
