Abstract
The utility model relates to a tool which is used in installation and decoration engineering, in particular to a nail supporting device, which comprises a tube body whose two ends are provided with openings. A handle extends on the outer wall of the tube body. A hammer body whose outer diameter is corresponding with the inner diameter of the tube body is arranged in the tube. The hammer is cylindrical, which is higher than the tube body. An opening is arranged on the bottom of the hammer. The upper and the lower end surfaces of the hammer are all flats, and a straight line groove which is connected with the opening is arranged between the lower end surface and the bottom of the hammer body. One end of the straight line extends out of the hammer body, and the other end extends to the center of the hammer bottom end. The utility model mainly solves the technology problem that the existing nail supporting mode is not beneficial for being operated by new learners, and is incapable to ensure the nail be vertically nailed, moreover the utility model ensures the personal safety in operation.
Description
Technical field
The utility model relates to installation, the instrument used of decoration engineering, particularly a kind of rotary screw device.
Background technology
Nail (comprising screw) is that use part, its effect mainly be exactly to fix for a kind of installation commonly used, decoration.On the structure, it comprises the strike portion of nail body and nail body one end, and the area of this strike portion is bigger, and adopts planar structure usually, sometimes, also has a word or cross recess (as: screw) on the plane.During use,, the nail body is hammered in the corresponding material by the scope of attack of knocking nail.
As everyone knows, nail has only vertically to hammer into just and can play best installation and fixed effect.And in the prior art, we adopt following dual mode to hold up nail usually:
1, by hand steered mode: this mode is applicable to those more experienced workmans usually, strength and angle when they can control knocking nail strike portion very effectively.
2, by helping with instruments such as pliers: still, the shortcoming of this mode is because pliers holds tension to the nail body usually, therefore, is unfavorable for controlling the dynamics of knocking, makes the nail nail askew easily.
But above-mentioned no matter which kind of holds up the nail mode, all not too is suitable for green hand's operation.In addition, the strike portion area of nail is less relatively, also is the reason that is unfavorable for that the green hand operates, and therefore may cause some injury accidents.
The utility model content
The purpose of this utility model is to provide a kind of rotary screw device, and mainly solve the existing nail mode of holding up and be unfavorable for that the green hand operates, and can not guarantee the technical problem that nail is vertically hammered into, and the personal safety in guaranteeing to operate.
For addressing the above problem, the utility model is achieved in that
A kind of rotary screw device is characterized in that: it comprises the cylindrical shell of a both ends open, is extended with the leader on this cylinder body outer wall, wears the body of beating that an external diameter and cylinder internal diameter match in this cylindrical shell; This beats body is cylindrical, its height is greater than the height of cylindrical shell, this is beaten the body bottom and is provided with a gap, the upper and lower end face of this gap is all the plane, and its lower surface and beating is provided with a straight-line groove that connects with gap between the body bottom surface, this straight-line groove one end extends to be beaten externally, and the other end extends to beats body bottom central authorities.
Described rotary screw device is characterized in that: it is a circular hole that this straight-line groove extends to an end of beating body bottom central authorities.
Described rotary screw device is characterized in that: this gap upper end with beat the height of the distance on body top greater than cylindrical shell.
By technique scheme, the beneficial effects of the utility model are:
1, have in the utility model rotary screw device can with the nail strong fix beat the body gap, and this surface area of beating the body upper end is relatively large, helps increasing the dynamics and the accuracy of hammer knocking.During use, can guarantee that nail is by vertically, firmly hammer in the object.
2, the utility model is operated by the handle that grips cylindrical shell one end in use, therefore is not easy the accident of damaging.

The specific embodiment
See also Fig. 1,2, they are structural representations of a kind of rotary screw device of the utility model.As shown in the figure: it comprises the cylindrical shell 1 of a both ends open, is extended with leader 2 on this cylindrical shell 1 outer wall, and what wear in this cylindrical shell 1 that an external diameter and cylindrical shell 1 internal diameter match beats body 3; This beats body 3 for cylindrical, its height is greater than the height of cylindrical shell 1, this is beaten body 3 bottoms and is provided with a gap 31, these gap 31 upper and lower end faces are all the plane, and its lower surface and beating is provided with a straight-line groove 32 that connects with gap 31 between body 3 bottom surfaces, these straight-line groove 32 1 ends extend to be beaten outside the body 3, and the other end extends to beats body 3 bottom central authorities.It is a circular hole 321 that this straight-line groove 32 extends to an end of beating body 3 bottom central authorities, and these gap 31 upper ends with beat the height of the distance on body 3 tops greater than cylindrical shell 1.
During use, please consult Fig. 3 earlier, the strike portion of nail 4 is arranged in the gap 31 of beating body 3, nail body upper end enters into the circular hole 321 of bottom central authorities simultaneously from straight-line groove 32.After nail 4 is packed into, will beat body 3 again and up draw, see also Fig. 4 along cylindrical shell 1 inwall.Then, use the position that rotary screw device is placed into nail location, again with beating body 3 upper ends in the hammer knocking cylindrical shell 1, can be vertically, firmly hammer in the object with nail.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
