Abstract

The utility model relates to a high-efficiency double-head screwdriver, composed of a handle and a double-head screw rod which is integrated with the handle. The two ends of the double-head screw rod are provided with different structures, wherein, one end of the screw rod forms an I-shaped, and the other end forms a cross shape. The high-efficiency double-head screwdriver is characterized in that the double-head screw rod is arranged in a cutter frame, and one end of the cutter frame near the handle is provided with a screw rod conversion locking mechanism composed of a spring and a clip ring. When the driver bit of the screw rod needs to be replaced, as long as the clip ring is gently pulled downward. The screw rod is turned and the clip ring is released. The utility model has the advantages of simple structure, convenient use, flexible and rapid driver bit conversion. The work efficiency can be improved, and the carrying and operation are also very convenient.

Description

Double-head screw-driver

The utility model relates to a kind of efficient double-threaded screw cutter, is formed by handle with this handle assembling all-in-one-piece lead screw.

Screwdriver is a kind of common installation or tears the specific purpose tool of driving screw open.Existing screwdriver is divided into two kinds on yi word pattern screwdriver and cross screwdriver according to the screw structure.Under many occasions, the operator need prepare the different screwdriver of two bar structures simultaneously, brings certain difficulty to practical operation.Notification number is to disclose a kind of screwdriver in the CN2140290Y utility model patent specification, this screwdriver is two ends in its handle of lead screw plug-in mounting of different structure shape, and respectively establish a lead screw locking device at the handle two ends, lead screw is fixed in the intracavity of handle, above-mentioned screwdriver locking device needs other it to be screwed allotment of labor's tool, and conversion lead screw complicated operating process, transposing speed is slow.

Characteristics such as the purpose of this utility model is to provide a kind of new and effective double-threaded screw cutter, and this screwdriver has simple in structure, and conversion is conveniently rapid.

The utility model above-mentioned purpose is to realize like this.

A kind of efficient double-threaded screw cutter, formed by handle ［ 6 ］ with the double-threaded screw bar ［ 5 ］ that these handle assembling all-in-one-piece two ends are different structure, wherein an end of lead screw ［ 5 ］ is a yi word pattern, it is cross that the other end is, it is middle to it is characterized in that said lead screw ［ 5 ］ is arranged on knife rest ［ 3 ］ by axle ［ 4 ］, and knife rest ［ 3 ］ one ends of close handle ［ 6 ］ are equipped with lead screw ［ 5 ］ the conversion locking mechanism that a cover is made up of spring ［ 1 ］ and snap ring ［ 2 ］.

Spring one end in the conversion locking mechanism of above-mentioned lead screw can be fixed as one with handle, also can fixedly be assemblied on the knife rest with snap ring.

The utility model integrates straight screwdriver head and Philip's head screw cutter head, maximum practical characteristics are to change cutter head fast, promptly in 1 second, just a word cutter head and cross cutter head can be exchanged, and it is simple to operate, easy to use, not only using straight screwdriver but also using just to have exempted in the work of Phillips screwdriver and use the normal screws cutter will put down wherein a kind of to go to take alternative trouble like this, solved again and used the dismounting of dismounting replaceable head screwdriver to change a time-consuming drawback and will not lose cutter head, improved operating efficiency greatly.In addition, it is easy to carry at work, durable and production cost is low, material-saving, and it is simple to do manual work.Just on simple finished screwdriver rod, increasing spring 1, snap ring 2 and double end knife bar 5, when changing, only need retract snap ring 2, turning knife bar 5, decontroling snap ring again and change a process and promptly in 1 short second, finish.

Introduce the utility model concrete structure below in conjunction with accompanying drawing:

Fig. 1 is the utility model embodiment one structural representation.

Fig. 2 is the utility model embodiment two structural representations.

Fig. 3 is the utility model lead screw transition status schematic diagram.

Among the figure, 1 spring, 2 snap rings, 3 knife rests, 4,5 double-threaded screw bars, 6 handles.

In the utility model, knife rest 3 is the fluted metallic object of a middle processing, lead screw 5 is linked and packed among knife rest 3 grooves by axle 4, snap ring 2 is connected as a single entity with spring 1, constitute the lead screw locking mechanism, be assemblied in knife rest one end near handle 6, snap ring 2 present positions just in time can lock screw bar 5, above-mentioned lead screw 5 one ends are yi word pattern, and it is cross that the other end is.Spring 1 can be fixing with handle 6 near handle 6 one sides, also can directly be fixed on the knife rest 3.
