DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all embodiments.

[0016] Examples of the embodiments are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0017] In the present application, unless specifically defined and limited otherwise, the terms "mounting", "connection", "connecting", "fixed", and the like are to be construed broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0018] Embodiment one: refer to Figures 1-4 The present application provides a technical scheme: a handheld anti-skid pistol drill, comprising a base 1, the top of the base 1 is fixedly connected with a butt 2, the end of the butt 2 away from the base 1 is fixedly connected with an impact gun 3, the inner wall of the impact gun 3 is rotatably connected with a drill bit 4, the inner wall of the butt 2 is slidably connected with an electric button 5.

[0019] The mounting mechanism 6 comprises a mounting block 601, the mounting block 601 is fixedly connected with the bottom of the impact gun 3, the left side of the mounting block 601 is fixedly connected with a control machine 602, the right side of the mounting block 601 is fixedly connected with a telescopic rod 603, the end of the telescopic rod 603 away from the mounting block 601 is fixedly connected with a containing cavity 604, the inner wall of the containing cavity 604 is provided with an adsorption assembly 605, the personnel holds the butt 2 of the pistol drill, presses the electric button 5 to start the power source of the pistol drill, drives the drill bit 4 to rotate to drill the surface of the punching material, before drilling, first start the control machine 602 switch, drive the telescopic rod 603 to slide outward, drive the containing cavity 604 to move to the surface of the punching material through the telescopic rod 603.

[0020] The adsorption assembly 605 comprises a plug block 6051 fixedly connected with the inner wall of the accommodating cavity 604, the surface of the plug block 6051 is fixedly connected with a folding frame 6052, and the inner wall of the folding frame 6052 is fixedly connected with a buffer clamp 6053. When the accommodating cavity 604 drives the adsorption plate 6055 to move to the surface of the perforated material, the surface of the perforated material is adsorbed by the adsorption plate 6055, so that the adsorption plate 6055 is fixed on the surface of the perforated material. When the drill bit 4 extends to the surface of the perforated material for drilling, the adsorption plate 6055 is compressed to the folding frame 6052 due to extrusion with the surface of the perforated material, so that the folding frame 6052 is inwards contracted and extrudes the buffer clamp 6053, thereby compressing the elastic tube 6054 in the buffer clamp 6053.

[0021] When the perforation is performed by the hand drill, the hand drill lacks effective support because it is manually held, so there is a certain requirement for the wrist strength of the worker, otherwise the drilling positioning deviation will be caused, and therefore the adsorption assembly 605 needs to be arranged.

[0022] The end, away from the plug block 6051, of the folding frame 6052 is fixedly connected with the adsorption plate 6055, and the inner wall of the buffer clamp 6053 is fixedly connected with the elastic tube 6054. After the perforation is completed, the adsorption plate 6055 is separated from the surface of the perforated material, and the elastic tube 6054 is ejected outwardly because it is not compressed, the folding frame 6052 is pushed by the ejected elastic tube 6054, so that the folding frame 6052 is reset. When the perforation is performed by the hand drill, the motor rotates to cause violent vibration during the drilling process, and the vibration is transmitted to the buttstock 2. If the holding force of the hands of the operator is small, the buttstock 2 is easily slid and displaced in the hands, and the positioning deviation during the drilling is caused. By arranging the mechanism, the hand drill is effectively supported, and the positioning deviation during the drilling is avoided.

[0023] The inner wall of the adsorption plate 6055 is mounted with double-sided adhesive tape, the elastic tube 6054 has the function of elastic expansion and contraction, and the folding frame 6052 has the characteristics of bending and folding. When the surface of the perforated material is adsorbed and fixed by the adsorption plate 6055, the adsorption plate 6055 can effectively adapt to the obviously inclined surface of the perforated material due to the bending and folding function of the folding frame 6052. Therefore, when the hand drill is used to perforate the surface of the perforated material with a special shape, the vibration will intensify the friction between the hands and the buttstock 2, a large amount of heat is generated, the high temperature will reduce the holding comfort of the hands, the holding stability is further improved by arranging the mechanism, and the risk of slipping is avoided.

[0024] In the embodiment one, continue to refer to Figures 5-6The present application provides a technical scheme: the telescopic mechanism 7 includes a mounting frame 701, the mounting frame 701 is fixedly connected with the surface of the base 1, the surface of the mounting frame 701 is fixedly connected with a telescopic cavity 703, the bottom of the telescopic cavity 703 is fixedly connected with a telescopic device 702, the telescopic device 702 is fixedly connected with the surface of the mounting frame 701, the inner wall of the telescopic cavity 703 is slidably connected with a telescopic frame 705, one end of the telescopic frame 705 away from the telescopic cavity 703 is provided with a clamping assembly 704, when the staff holds the butt 2, the telescopic device 702 switch is started, so as to drive the telescopic frame 705 to slide in the telescopic cavity 703, the telescopic frame 705 can drive the telescopic rope 7043 to move to the direction of the butt 2, when the telescopic frame 705 continues to slide in the telescopic cavity 703.

[0025] When the staff holds the hand drill to drill, when drilling on the inclined or special-shaped material surface, due to the lack of targeted adsorption or buffer structure, not only the drilling accuracy is difficult to guarantee, but also the operation fatigue is caused due to vibration superposition, so that the risk of the hand drill slipping in the staff's hand appears, so it is necessary to set the clamping assembly 704.

[0026] The clamping assembly 704 includes a contraction ring 7041, the contraction ring 7041 is fixedly connected with one end of the telescopic frame 705, one end of the contraction ring 7041 away from the telescopic frame 705 is fixedly connected with a side disc 7042, the surface of the side disc 7042 is fixedly connected with a telescopic rope 7043, one end of the telescopic rope 7043 away from the side disc 7042 is fixedly connected with a clamping ring 7044, the inner wall of the clamping ring 7044 is fixedly connected with an adsorption disc 7045, so that the telescopic rope 7043 drives the clamping ring 7044 to move inward and coat the staff's hand, the adsorption disc 7045 on the inner wall of the clamping ring 7044 adsorbs the staff's hand, and the clamping ring 7044 connected with the plurality of telescopic ropes 7043 can match the size of the staff's hand, when the staff holds the butt 2 and punches through the hand drill, the vibration transmitted to the staff's hand will make the contraction ring 7041 shrink inward, by providing the above-mentioned auxiliary fixing structure, the wrist strength requirement of the operator can be reduced, and the hand drill slipping in the staff's hand caused by vibration during the drilling process can be avoided.
