A hammer includes a hammer head and a hammer handle arranged on one side of the hammer head, the hammer head includes an upper hammer head and a lower hammer head that is movably connected to the upper hammer head through connecting rods arranged around the top of the upper hammer head, A clamping groove is arranged symmetrically at the bottom of the upper hammer head and the top of the lower hammer head away from the hammer handle respectively. The two clamping grooves are closed to form a wedge-shaped groove. There is a concave cavity on the top of the lower hammer head. There is a rack, and a cavity is vertically provided in the position corresponding to the cavity of the lower hammer in the upper hammer head, and a left clamping rod and a right clamping rod hinged by a rotating shaft vertically pass through the upper hammer head cavity and extend to the lower hammer In the concave cavity of the head, the two ends of the rotating shaft are respectively connected with the two side walls of the cavity of the upper hammer head. There are hooks on the outer sides of the lower ends of the left clamping rod and the right clamping rod to match the racks on both sides of the cavity. There is a locking device on the upper end of the rod and the right clamping rod, and several threaded holes are respectively provided on the hammer handle on the side connected with the lower hammer head. heavy block.

The locking clamping device is a buckle that is movable and hinged on the outer side of the upper end of the left clamping rod, and the free end of the buckle is clamped on the outer side of the upper end of the right clamping rod.

An anti-skid sleeve is arranged on the tail end surface of the hammer handle.

A dust-proof cover is movably clamped on the top of the cavity of the upper hammer head.

The beneficial effect of the utility model is that the design is reasonable, the operation is simple, the size of the gap at the nail pulling part of the hammer can be adjusted, and nails with different diameters can be pulled out, the utility model has strong versatility, unlimited use, and the weight of the hammer head part can be adjusted. Adjustment can be used to counterweight the hammer head according to different situations, which saves time and effort, has obvious knocking effect, and is convenient to carry, which solves the problems existing in the prior art.

detailed description:

In order to clearly illustrate the technical features of this solution, the utility model will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

As shown in the figure, a hammer includes a hammer head and a hammer handle 11 arranged on one side of the hammer head. The upper hammer 1 is movably connected to the lower hammer 2, and the bottom of the upper hammer 1 and the top of the lower hammer 2 are respectively symmetrically provided with a clamping groove 9 at the end away from the hammer handle 11. The two clamping grooves 9 are closed to form a wedge-shaped groove. 2 There is a concave cavity on the top, a rack 4 is symmetrically arranged on both sides of the concave cavity, a cavity is vertically provided in the upper hammer 1 corresponding to the concave cavity of the lower hammer 2, and a cavity is arranged through the rotating shaft 7 The hinged left clamping rod 5 and the right clamping rod 6 vertically pass through the cavity of the upper hammer head 1 and extend to the concave cavity of the lower hammer head 2. The outer sides of the lower ends of the left clamping rod 5 and the right clamping rod 6 are respectively provided with hooks 15 that match the racks 4 on both sides of the concave cavity, and a locking device is provided at the upper ends of the left clamping rod 5 and the right clamping rod 6. The hammer handle 11 on the side where the head 2 is connected is respectively provided with several threaded holes 12, and a counterweight 13 used in conjunction with the threaded holes 12 is movably inserted in the tail end of the hammer handle 11.

The locking clamping device is a buckle 8 that is movable and hingedly arranged on the outer side of the upper end of the left clamping rod, and the free end of the buckle 8 is clamped on the outer side of the upper end of the right clamping rod.

An anti-slip sleeve 14 is provided on the tail end surface of the hammer handle 11 . The frictional force between the hand and the hammer handle 11 is increased, making it convenient for the operator to grasp the hammer handle 11 .

A dustproof cover 10 is movably clamped on the top of the cavity of the upper hammer head 1 . Prevent dust from falling from the top of the upper hammer head 1 cavity at ordinary times, and improve the service life.

When it is necessary to use a hammer to pull out a nail wedged in other objects, if it is found that the wedge-shaped groove formed by the clamping groove 9 on the upper hammer head 1 and the lower hammer head 2 does not conform to the diameter of the nail to be pulled out, put the dust cover 10 Pull it out, then open the buckle 8 on the upper end of the left clamping rod 5 and the right clamping rod 6, and open the left clamping rod 5 and the right clamping rod 6 outward by hand, The hook 15 on the side is separated from the racks 4 on both sides of the concave cavity of the lower hammer 2, and then, lift the upper hammer 1 upward until the gap between the upper hammer 1 and the lower hammer 2 matches the diameter of the nail to be pulled out , close the upper ends of the left clamping rod 5 and the right clamping rod 6, and then lock it with the buckle 8. At this time, the hook 15 on the outside of the lower end of the left clamping rod 5 and the right clamping rod 6 is reconnected with the lower hammerhead 2 cavity The inner rack 4 is fastened, and finally, use a hammer to pull out the nail to complete the work, and cover the dust cover 10 after use. When it is necessary to adjust the weight of the tup, the counterweight 13 at the tail end of the hammer handle 11 can be taken out one by one according to the needs of the counterweight, and threaded on the threaded hole 12 of the hammer handle. Large, while the length of the entire hammer handle 11 does not change, saving time and effort, the effect of knocking and smashing is obvious, and it is easy to carry.

The above-mentioned specific implementation manners cannot be regarded as limitations on the protection scope of the present utility model. For those skilled in the art, any alternative improvements or transformations made to the embodiments of the present utility model fall within the protection scope of the present utility model.

The parts of the utility model that are not described in detail are the known techniques of those skilled in the art.
