Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fine decoration punching, in particular to an adjustable blind hole punching device. Background Art
[0002] In today's fine decoration engineering field, the drilling of stone, wood, etc. is no longer limited to the scope of full drilling. In most cases, non-penetrating holes, namely blind holes, need to be drilled. However, there is no special non-penetrating drilling component or device in the prior art. Generally, an electric drill bit is directly connected to a cutter head to perform blind hole drilling operations on the surface of the material. Although this is more convenient and easy, the degree of completion of the drilling is relatively low when drilling in this way, and it is more challenging to the technical level of the operator. Once the operation is improper, it is easy to damage the material. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The utility model provides an adjustable blind hole punching device, comprising a guide, which is cylindrical. A rotating rod is arranged in the guide, and the rotating rod passes through the guide and can rotate in the guide; a reinforcement plate is arranged at the bottom end of the rotating rod, and a scraper for drilling holes is fixedly arranged on the lower end surface of the reinforcement plate; the rotating rod is located on the outer side of the rod body of the upper part of the guide, and a plurality of limit grooves are arranged at intervals along the length of the rod body, and limit rings are clamped in the limit grooves.
[0006] Preferably, a dust cover is provided at the bottom of the guide and is connected to the dust cover, and the shaft of the rotating rod located at the lower part of the guide and the reinforcement plate are both located in the dust cover.
[0007] Preferably, the dust cover is a cylindrical shell with an opening facing downward, and anti-slip teeth are provided on the edge of the opening of the dust cover.
[0008] Preferably, the limiting ring comprises a ring body and blocking pieces arranged at both ends of the ring body for limiting.
[0009] Preferably, the reinforcement disk is circular, the scraper is cross-shaped, and the transverse length and longitudinal length of the scraper are not greater than the diameter of the reinforcement disk.
[0010] Preferably, at least five limiting grooves are provided.
[0011] Preferably, the reinforcement plate and the rotating rod are detachably connected.
[0012] The beneficial effects of the utility model are embodied in:
[0013] 1) The utility model provides an adjustable blind hole punching device. A limit groove is provided on the shaft of the rotating rod. Through the cooperation of the limit groove and the limit ring, the depth of the rotating rod inserted into the guide can be adjusted, thereby adjusting the depth of the punching and controlling the straightness of the radial position of the punching. The reinforcement disc and the scraper can be replaced, so the size of the punching can be controlled, which has strong flexibility.
[0014] 2) The utility model provides an adjustable blind hole punching device, in which a dust cover is arranged at the lower part of the guide, which can completely cover the reinforcement plate and the scraper to prevent the splashing of material debris during the drilling process. After the drilling is completed, it is convenient to collect and process the material debris, ensuring the cleanliness and hygiene of the construction site.
[0015] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The main purpose and other advantages of the utility model can be realized and obtained by the solutions particularly pointed out in the description. BRIEF DESCRIPTION OF THE DRAWINGS
