Technical Field

The utility model relates to a tool specifically is a hand-held type twists screw ware.

Background

The screw is a tool for fastening the parts of the object step by utilizing the physics and mathematical principles of the inclined circular rotation and friction of the object. The screw is indispensable industry requisite in daily life: extremely small screws used for cameras, glasses, clocks, electronics, and the like; general screws for televisions, electric appliances, musical instruments, furniture, and the like; large screws and nuts are used for engineering, buildings and bridges; transportation equipment, airplanes, electric cars, automobiles, and the like are used with screws of different sizes. The screw has an important task in industry, and as long as there is industry on earth, the function of the screw is always important. The screw is a common invention in production and life of people for thousands of years, and is the first invention of human according to the application field.

While a screwdriver is a tool used to turn a screw to a desired position, usually having a thin wedge-shaped head that is inserted into a slot or recess in the head of the screw, a versatile configuration for replacing the screwdriver bits is also currently available.

However, the existing screw driver is still a whole when in use, and the hand of a user is easily sour when the screw is screwed down and unscrewed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a hand-held type twists screw ware to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a hand-held type screwdrivers, criticizes head, criticize first connecting rod and threaded rod including handle, screw hole, guiding hole, screwdriver, the one end of handle inwards coaxial set up threaded hole, the other end of handle inwards coaxial set up the guiding hole, communicate between guiding hole and the screw hole, and the internal diameter of guiding hole is less than the internal diameter of screw hole, threaded hole female connection threaded rod, threaded rod are connected with the one end of criticizing first connecting rod towards the one end integrated into one piece of guiding hole, criticize first connecting rod and set up in the guiding hole, criticize the interior hexagonal hole of inwards coaxial seting up of other end tip of first connecting rod, and this interior hexagonal hole is used for grafting screwdriver criticizing.

As a further aspect of the present invention: the handle is made of plastic or stainless steel.

As a further aspect of the present invention: the handle is the column and the surface of handle is formed with the concave convex pattern that is used for increasing hand frictional force.

As a further aspect of the present invention: the other end of the threaded rod is integrally connected with one end of an extension rod, and the other end of the extension rod is fixedly connected with one side of the clamp.

As a further aspect of the present invention: the clamp is a metal clamp, a through hole is formed in one side of a clamp opening of the clamp, and a corresponding screw penetrates through the through hole and is in threaded connection with a threaded hole formed in the other end of the extension rod.

Compared with the prior art, the beneficial effects of the utility model are that: this practicality has changed the mode that traditional screwed the screw, changes into on two parts that can relative motion with two traditional hands function in a holistic screwdriver to slow down the tired sense that the hand produced fast when screwing the screw.

In addition, the clamp is fixed at the other end of the extension rod, so that the effect of increasing the force arm can be realized, and the effect of conveniently clamping the carrier to carry and prevent the carrier can be achieved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying 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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, in the embodiment of the present invention, a hand-held screwing device includes a handle 1, a threaded hole 2, a guiding hole 3, a screwdriver bit 4, a bit connecting rod 5, a threaded rod 6, an extension rod 7 and a clip 8, wherein the handle 1 is cylindrical, and the outer surface of the handle 1 is formed with a concave-convex pattern for increasing the friction force of the hand, so as to ensure that one hand can stably hold the screw when in use, one end of the handle 1 is provided with the threaded hole 2 coaxially inward, the other end of the handle 1 is provided with the guiding hole 3 coaxially inward, the guiding hole 3 is communicated with the threaded hole 2, the inner diameter of the guiding hole 3 is smaller than the inner diameter of the threaded hole 2, the threaded hole 2 is connected with the threaded rod 6 internally, one end of the threaded rod 6 facing the guiding hole 3 is integrally formed with one end of the bit connecting rod 5, the bit connecting rod 5 is disposed in the threaded hole 2, the other end of the, this interior hexagonal hole 9 is used for pegging graft screwdriver bits 4 to can the through-hole control handle 1 rotate with threaded rod 6 relatively when using, twist into and screw out the screw of the effect of screwdriver bits 4 department in order to realize.

The handle 1 can be made of plastic, stainless steel and the like, so that the overall weight is light.

The other end of the threaded rod 6 is integrally formed and connected with one end of the extension rod 7, the other end of the extension rod 7 is fixedly connected with one side of the clamp 8 through a screw, the clamp 8 can provide a position for holding by another hand, and meanwhile, the force arm is increased through the clamp, so that the screw rotation is convenient and labor-saving.

The clamp 8 is a metal clamp, a through hole is formed in one side of a clamping opening of the clamp 8, a corresponding screw passes through the through hole and is in threaded connection with a threaded hole formed in the other end of the extension rod 7, and the clamp 8 can be clamped on a carrier in the process of not using and carrying so as to be convenient to carry.

Wherein screwdriver bits 4 and its complex hexagon socket 9 all adopt for current specification make can, it does not influence the realization of other structures of this application.

This practicality is through threaded rod 6 and screw hole cooperation change the hand when twisting the screw hard, all act on this application can be used for respectively on handle 1 and threaded rod 6 from originally pressing down with the rotation on integrative screwdriver to for the screw provides lighter possibility, can change the arm of force and shorten overall structure etc. through changing 1 diameters of handle promptly, thereby conveniently carry, can hide comparatively sharp-pointed one end in the guiding hole when not using simultaneously.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
