Abstract

The utility model relates a penetrable screwdriver structure. A metal knock head is fixedly arranged at the back side of a plastic grab handle, and a hexagonal rod body is arranged inside the grad handle. One end of the rod body is connected to the knocking head, the other end is extended out of the front end of the grab handle; wherein, the position of the rod body at the front end of the grab handle is equipped with a knocking rotary mechanism, and the front end of the knocking rotary mechanism can be sleeved with a screwdriver tool. In this way, when the grab handle is knocked, the screwdriver tool is made a rotary action at the moment of knocking by the knocking rotary mechanism, in order to disassemble or assemble the locking components, thereby achieving the efficacies of convenient operation and easy use.

Description

Through screwdriver structure

Technical field

The utility model relates to a kind of through screwdriver structure, utilizes the anti-characteristic of knocking of through bottle opener light weight, increases to have the effect of the rotation of knocking, and then makes instrument knock when using easier mounting or dismounting locked assembly.

Background technology

See also Fig. 1, Fig. 2, the general bottle opener that uses, it is the jack 3 that there is slot 2 the straight forming both sides on plastics lever 1, another sub bar 4 its both sides have fin 5, and screwdriver rod 4 can be forced in the lever 1, and be sticked in slot 2 with fin 5, make lever 1 when rotated, can drive screwdriver rod 4 rotations simultaneously, to carry out the dismounting operation of locked assembly; Yet, some locked assembly (as bolt) is impaired because of corrosion or tooth line, and can't directly rotate dismounting with general bottle opener, and after must being knocked vibrations earlier, could come turn, and as the bottle opener of Fig. 1, Fig. 2 with bottle opener, its lever 1 provides the effect of user's light weight easy operating to make with plastics because of considering, the relative vibrations of just can't knocking are used, and in order to improve this situation, promptly have the dealer to design a kind of through bottle opener.See also Fig. 3, Fig. 4, the lever 6 of the through bottle opener of this kind still adopts plastics to make, and have a characteristic that the light weight easy operating uses, but when lever 6 moulding, set firmly the metallic striking head 7 of a step shape in its back-end, the miner diameter end 8 of striking head 7 front ends is coated in the lever 6, the miner diameter end 8 of this striking head 7 is provided with hole, angle 9, another sub bar 10 its shafts are horn shape, lever 6 is when ejection formation, and the body of rod one end of screwdriver rod 10 inserts in the hole, miner diameter end angle 9 of striking head, and links with metallic striking head 7, and after lever 6 moulding, be coated on lever 6, make lever 6 when manipulating, can drive striking head 7 and screwdriver rod 10 rotations simultaneously, because through bottle opener rear end has the anti-metallic striking head of knocking 7, so when being difficult for rotating the locked assembly use of removing, can knock vibrations by the lever rear end, and interlock is to the screwdriver rod 10 that links, and then can knock vibrations and use, and lever 6 still has the characteristic that light weight is easy to grip.Though this through bottle opener can knock use, but in the process that reality is used, even if the bolt of corrosion is after knocking, still need impose sizable strength just can be rotated, very and still motionless as the mountain, for the bolt that is difficult at this extreme removing, the dealer is the removal tool of a kind of special use of otherwise designed.See also Fig. 5, Fig. 6, the instrument that knocks of this special use, its lever 11 integral body are made for metal material turning, so can be for knocking, its front end is provided with a trepanning 12, offer two relative V-type grooves 13 on the side ring wall of trepanning 12 relatively, behind the trepanning 12 interior sheathed springs 14, be inserted in a tool heads 15 again, utilize a pin 16 the stretch through perforation 17 and the V-type groove 13 of tool heads 15, tool heads 15 is compressible spring 14, and move along V-type groove 13 by pin 16, so when knocking lever 11, tool heads 15 can be clashed into and be shaken bolt, and the moment of clashing into, tool heads 15 can be subjected to the anti-power of work and compress spring 14, pin 16 moves to end point along 13 declines of V-type groove at this moment, mobile (as shown in Figure 7) that spring 14 elastic force that continue make pin 16 do to rise, and this V-type path is mobile, promptly produce the rotate effect of horizontal displacement, therefore can hold concurrently and the effect of generation turn in the moment of knocking, make bolt more easy to assemble; But this knocks instrument can be that metal is made for knocking because of lever is required to be, so heaviness very, when the follow-up turn operation of finishing after knocking, common people are difficult to load and make the rotary manipulation that continues, and must change general lighter bottle opener instrument (as the bottle opener of Fig. 2), therefore be difficult to take into account the purpose of light easy operating in the use.

Summary of the invention

Main purpose of the present utility model provides a kind of through screwdriver structure, coat binding one metallic striking head in the rear end of lever, another extends the body of rod of lever front end, the one end is linked to metallic striking head, the other end then links and knocks rotating mechanism, but this front end that knocks rotating mechanism socket bottle opener instrument then; By this, utilize through Screwdriver handle, not only can be for knocking use, and lever lightly is easy to holding operation, more can drive the bottle opener instrument and do the turn of horizontal displacement in the moment of knocking and knock rotating mechanism, and then can be easier to the turn locked assembly, is convenient to dismounting.

Another purpose of the present utility model provides a kind of through screwdriver structure, wherein, the lever system of this through bottle opener is with the plastics ejection formation, and has the characteristic that light weight is easy to holding operation, finish knock rotation after, can continue and use direct turn locked assembly, and need not change the bottle opener instrument of lightweight, reach the effect of multiple use.

Above-mentioned purpose of the present utility model is achieved in that a kind of through screwdriver structure, it is characterized in that comprising: lever; The striking head of metal material coats the rear end that is linked to lever; The body of rod is extended through in the lever, and rear end and striking head link; Knock rotating mechanism, be fixedly arranged on the front end of the body of rod, its front end convergence part socket dismantling device.

Above-mentioned purpose of the present utility model can also realize that so a kind of through screwdriver structure is characterized in that comprising: lever; The striking head of metal material coats the rear end that is linked to lever; The body of rod is extended through in the lever, and its rear end and striking head link; Block set is fixedly arranged on the leading section of the body of rod, is provided with a trepanning, and offers two relative V-type grooves on the side ring wall of corresponding trepanning; Spring is placed in the trepanning of block set; The start head is placed in the trepanning of block set, and compresses spring, which is provided with the perforation of a corresponding V-type groove, and to cover a pin, the pin two ends are placed on the V-type groove, the front end convergence part socket dismantling device of start head.
