The hammer handle is composed of the semi-elliptic cylinders on two sides and the cuboid in the middle, and people respectively control and use the flat screwdriver, the cross screwdriver and the saw through the three push-pull devices on the hammer handle, so that the carrying of construction tools is reduced, and the use is very convenient.

Description

Adjustable multifunctional pulling hammer

Technical Field

The utility model relates to a multi-functional civil construction instrument especially relates to a multi-functional hammer of pulling with adjustable.

Background

At present, the known hammers are widely used in various fields, in particular in the field of construction. However, the hammer used by people at present has a single function, and tools such as a wrench, a screwdriver, a saw and the like are often required to be carried while the hammer is used, so that the worker is very inconvenient.

Firstly, the hammer is used for nailing, but the traditional hammer has no function of fixing nails, so that a worker easily smashes hands; secondly, for example, when using accessories such as expansion bolts, a hammer and a wrench are inevitably used at the same time, and a worker uses a single-function tool alternately, which seriously affects the working efficiency.

Disclosure of Invention

In order to overcome the potential safety hazard scheduling problem that traditional hammer service function is single and the nailing exists, the utility model provides a multi-functional hammer of pulling with adjustable not only can avoid pounding in one's hands, combines several kinds of instruments commonly used moreover, convenient to carry, convenient to use.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: an adjustable multifunctional spanner hammer is composed of a hammer handle, a hammer head, a bolt, a movable nut, a screwdriver and a saw blade, wherein the hammer handle and the hammer head are of an integral structure, one end of the hammer head is not processed, the other end of the hammer head is made into a concave opening, and the size of the concave opening is controlled by adjusting the bolt through a bolt hole beside the side of the hammer head. The hammer handle sets up to middle cuboid, the semiellipse body structure of both sides is used for setting up the saw bit in the middle cuboid, sets up plain end screwdriver and cross screwdriver in the semiellipse body of both sides respectively, and these triplex all shrink through the push-and-pull device that sets up on the hammer handle, pushes away certain length and can block die. The outside of the hammer handle is sleeved with a rubber sleeve for skid resistance.

As the improvement, the utility model discloses set up the bolt hole, adjust the opening size through the bolt and the movable nut of cover on the hammer head for press from both sides the screw cap of tight not unidimensional size.

Further, if a hammer is used for nailing, a blunt head of the nail can be placed into the concave hole, then the nail is fixed by the adjusting bolt and the movable screw cap, and then the nail is hammered into a certain object, so that the fixation by hands is avoided, and the injury to the hands by hammering is prevented.

As the durability and the comfort level are improved, the saw blade is in a long right-angle trapezoid shape, and the hammer head can be directly held by hands when the hammer is used.

The beneficial effects of the utility model are that can combine together the function of hammer, spanner, pliers, adjust the opening size through the bolt, not only play the effect of screwing up not unidimensional screw cap, still fixable nail simultaneously eliminates safe worry. Secondly, set up instrument such as saw bit, screwdriver on the hammer handle, only need the little device on the push-and-pull spout, can use different instruments, wherein, when using the screwdriver, the both ends of hammer head just are regarded as the handle, as screwing up the device, it is very convenient to use.

In the figure, 1, a hammer handle, 2, a hammer head, 3, a flat screwdriver push-pull switch, 4, a movable nut, 5, a bolt, 6, a bolt hole, 7, a flat screwdriver, 8, a cross screwdriver, 9, a saw blade, 10, a sawtooth push-pull switch, 11, a cross screwdriver push-pull switch and 12, a rubber sleeve are arranged.

Detailed Description

As shown in fig. 1 and 2, the adjustable multifunctional wrench hammer comprises a hammer handle (1) and a hammer head (2), wherein a bolt (5) is connected with the hammer head (2) through a bolt hole (6) with threads on the inner wall, and a movable nut (4) is sleeved on the bolt (5). The top view of the hammer handle (1) is shown in figure 3, a saw blade (9) is sleeved in the middle cuboid part, the contraction is controlled through a saw blade push-pull switch (10), a flat screwdriver (7) and a cross screwdriver (8) are respectively sleeved in the semiellipsoids on the two sides, the flat screwdriver (7) is contracted through the flat screwdriver push-pull switch (3), and the cross screwdriver (8) is contracted through the cross screwdriver push-pull switch (11).

The tail end of the hammer handle (1) is provided with a rubber sleeve (12) to prevent slipping in the use process.

The working principle of the utility model is that when people screw a certain screw, the hammer handle (1) can be held by hand, the screw cap to be screwed is placed in the concave notch, the screw cap to be screwed is clamped through the adjusting bolt (5) and the movable nut (4), and then the hammer handle (1) is rotated; when people nail, can put into the spill notch with the blunt head of nail, then adjust bolt (5) and movable nut (4) equally, after the nail was fixed, hold hammer handle (1) with the hand and pound the nail into the object can.

When the hammer is used, if a saw and a screwdriver are needed, the push-pull switches (10), (3) and (11) are directly pushed to respectively use the saw blade (9), the flat screwdriver (7) and the cross screwdriver (8), and after the hammer is used, the hammer can be withdrawn through the push-pull devices (10), (3) and (11), so that the hammer does not need to be rotated by one tool, and the hammer is very convenient to use.
