Abstract
The utility model discloses a puncher allowing the depth to be controllable. The puncher comprises a clamping handle, a drilling rod, a drill bit and a clamping ring, one end of the drilling rod is fixed to the clamping handle, and the periphery of the drilling rod is provided with external threads; the clamping ring is arranged on the periphery of the drilling rod in a sleeved mode and is in screw-thread fit with the drilling rod; the drill bit is arranged at the other end of the drilling rod and provided with spiral teeth; the diameter of the drill bit is equal to the major diameter of the external threads. According to the puncher, the periphery of the drill bit is provided with the external threads and provided with the clamping ring in the sleeved mode, the clamping ring is in screw-thread fit with the external threads of the drill bit, the position of the clamping ring can be regulated by rotating the clamping ring in a drilling process, the distance between the clamping ring and the end of the drill bit is the depth of a drilled hole, the drill bit drills into the clamping ring and is clamped on the surface of a decorative sheet in the drilling process, and controllability of the depth of the drilled hole is achieved.
Description
Technical field
The utility model relates to a kind of instrument in decorations, is specifically related to a kind of card punch of controllable depth.
Background technology
In the time that dalle is arranged on support keel, normally adopts and be screwed.Because dalle has certain thickness; in the time that dalle is installed; need to adopt length to be greater than the screw of dalle thickness; and different dalles, its thickness is not identical, therefore; the dalle of different-thickness is installed; need to mate the screw of different length, this not only installs very inconvenient, and usually there will be screw length to be less than the situation of dalle thickness.In order to address this problem, when mounted, first on dalle, make a call to a screw hole with card punch, and then oncomelania is followed closely in screw hole, and dalle and support keel are fixed together.In the time of punching, the punching degree of depth of card punch is all manual controls, the degree of depth for punching is difficult to accurate grasp, if drilling depth is inadequate, and cannot mounting screw, if drilling depth is too dark, can affect the fastness of dalle, especially for thinner dalle, if severity control is bad, be easy to be punched, cause dalle cannot install and can only abandon.
Summary of the invention
For above-mentioned deficiency of the prior art, the utility model provides a kind of device of beating that can control the punching degree of depth.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The card punch of controllable depth, comprises clamp holder, drilling rod, drill bit and collar, and one end of drilling rod is fixed on clamp holder, is provided with external screw thread in the periphery of drilling rod; Described collar is set in the periphery of drilling rod and coordinates with drill rod thread; Described drill bit is arranged on the other end of drilling rod, and drill bit is provided with helical tooth; The diameter of described drill bit equals externally threaded large footpath.
Further, described helical tooth is triangle helical tooth.
Further, the tapered drill bit plane that protrudes from of described helical tooth.
With respect to prior art, the utlity model has following beneficial effect:
The utility model is because the periphery at drill bit is provided with external screw thread, at the sheathed collar of periphery of drill bit, this collar and drill bit external screw thread threaded engagement, in the time of boring, can, by rotation collar, adjust the position of collar, collar is drilling depth to the length of drill bit end, in the time of boring, bit drills proceeds to collar and is stuck in surface of decorative plate, has realized the controlled of drilling depth.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view;
Fig. 3 is Fig. 2 left view.
Wherein, 1 is clamp holder, and 2 is drilling rod, and 3 is drill bit, and 4 is collar, and 5 is helical tooth.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1 ~ Fig. 3, the card punch of controllable depth comprises clamp holder 1, drilling rod 2, drill bit 3 and collar 4.Clamp holder 1 for being connected with electric drill in the time punching.One end of drilling rod 2 is fixedly connected with clamp holder 1, is provided with external screw thread in the periphery of drilling rod 2, collar 4 be set in the periphery of drilling rod 2 and with drilling rod 2 threaded engagement.Collar 4 plays position-limiting action in punching process.Before punching, can first adjust the position of collar 4 according to punching projected depth, in the time of punching, card punch creeps into collar 4 and is stuck in surface of decorative plate, has realized the punching degree of depth controlled.Drill bit 3 is fixed on the other end of drilling rod 2, on drill bit 2, is provided with helical tooth, to ensure that card punch is in the time holing, the accuracy in aperture.The tapered drill bit plane that protrudes from of helical tooth 5, this helical tooth 5 is triangle helical tooth, for convenient to whose punch position in the time punching, in the time of punching, play the guiding role, and prevents that grooved bit 3 wanders off in the time of punching.Drill bit 3 is formed in one with drilling rod 2, and the diameter of drilling rod 2 is less than the diameter of drill bit 3, and the externally threaded large footpath of drilling rod 2 equals the diameter of drill bit 3, and externally threaded crest flushes with drill bit 3 outer surfaces.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
