Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The first embodiment is as follows:

referring to fig. 1-4, the multifunctional nail hammer convenient for pulling out nails of various lengths comprises a hammer handle 1 and a hammer tail 3, wherein an external thread 4 is arranged at the end part of the hammer handle 1, a first internal thread 6 is arranged in the middle of the side wall of the hammer tail 3, and the hammer tail 3 is in threaded connection with the external thread 4 at the end part of the hammer handle 1 through the first internal thread 6;

a second internal thread 7 is formed in one side, away from the first internal thread 6, of the hammer tail 3, the fixing block 5 is in threaded connection, and a hammer head 2 is fixedly connected to one side, away from the hammer tail 3, of the fixing block 5;

through the structure setting, at first utilize the screw thread precession relation, fix hammer handle 1 and hammer tail 3, tup 2 is fixed with hammer tail 3, form wholly, when the nail to different length, at first place the nail groove in the nail, pull hammer handle 1 afterwards, thereby extract the nail completely, when the nail has pulled a certain position and can't extract, with hammer tail 3 along the fulcrum position of hammer handle 1 axial activity change about the time of pulling out the nail, thereby utilize the nail of pulling out various lengths that lever principle can be very light, be applicable to the various places that need pull out the nail, and is simple and fast, and the function is practical.

The length of the thread of the external thread 4 is greater than that of the first internal thread 6, and the length of the thread of the fixing block 5 is the same as that of the second internal thread 7;

through the structure setting, the thread length who utilizes external screw thread 4 is greater than the thread length setting of first internal thread 6 to make hammer tail 3 can reciprocate along hammer handle 1 when rotating hammer handle 1, can extract the nail that various length are different, simple structure, convenient operation, fixed block 5 is the same with the thread length of second internal thread 7 simultaneously, utilizes the screw thread precession relation, makes and can form a whole between tup 2 and the hammer tail 3, improves holistic pleasing to the eye degree.

Wherein, one end of the hammer tail 3 far away from the second internal thread 7 is provided with a nail nipping groove which is arranged in a V-shaped structure;

through the structure, the nail nipping groove can play a nail nipping role, and the practicability is high.

Wherein, one end of the hammer handle 1 far away from the external thread 4 is fixedly connected with a fixed sleeve 8, and the fixed sleeve 8 is made of rubber;

through the setting of above-mentioned structure, fixed cover 8 passes through the rubber material setting, and the machine-shaping of being convenient for, the cost is lower moreover, and rubber is the elastomer simultaneously, and handheld meeting generated pressure is sunken, can form arc form face contact increase resistance and friction surface, forms anti-skidding trend to prevent that hammer handle 1 from taking place to drop.

Wherein, a protection ring 9 is arranged at one end of the hammer handle 1 far away from the external thread 4, the protection ring 9 is rotationally connected with the outer wall of the hammer handle 1, and the protection ring 9 is arranged in a semicircular structure;

through the structure arrangement, the palm firstly penetrates through the protection ring 9 by utilizing the arrangement of the protection ring 9, and then the hammer handle 1 is rotated, so that the protection ring 9 can rotate according to the hammer handle 1, and the condition that the hammer handle 1 cannot fall off can be ensured.

The second embodiment:

referring to fig. 4, in the multifunctional nail hammer for conveniently pulling out nails of various lengths, a hammer tail 3 is in threaded connection with an external thread 4 at the end of a hammer handle 1 through a second internal thread 7;

through the structure, the external thread 4 is connected with the second internal thread 7 through the thread, so that a simple crowbar can be formed, the working efficiency of the crowbar is improved, the purposes of safety, time saving, labor saving and high efficiency are achieved, meanwhile, the simple crowbar is formed, the carrying of tools can be reduced, the crowbar is a labor tool, and a method for lifting heavy objects from the ground and generating displacement by overcoming the gravity of the objects which cannot be moved by manpower through the lever principle is adopted.

In the utility model, firstly, the hammer handle 1 and the hammer tail 3 are fixed by utilizing the screw thread precession relation, and the hammer head 2 and the hammer tail 3 are fixed to form a whole, when a longer nail needs to be extracted by using the hammer tail 3, the hammer tail 3 is moved upwards a little along the hammer handle 1 because the protruding material of the tail part of the long nail is very high, so that the longer nail is conveniently extracted; when long nails do not need to be pulled out or nails need to be knocked by the hammer head 2, the hammer head 2 can be detached when a crowbar is needed, the hammer handle 1 is connected with the hammer tail 3 to form the crowbar, and the crowbar is a labor tool and is a method for lifting heavy objects from the ground and displacing the heavy objects by overcoming the gravity of the earth by using the lever principle.
