Description

The hand-operated tools structure

The utility model relates to a kind of hand-operated tools structure, promptly is applied to the hand-operated tools of the various screws of demolition, installation, nut, such as screwdriver, relates in particular to a kind of hand-operated tools structure that two kinds of modes of operation can be provided.

Screw, nut are to use the most general binding member at present, utilize screw, nut can be firmly in conjunction with two articles, yet adopt the full element of knot such as screw when carrying out binding operation, for example must adopt hand-operated tools or other automated tools (electric tool or pneumatic tool) such as screwdriver; Discuss with screwdriver, the kind of present visible screwdriver is quite a lot of, at least comprise a lever and a screwdriver head that is incorporated into lever haply, wherein screwdriver head can be different according to the state that can plant different screws, nut, such as manifold, crosshead, wabbler or sleeve are first-class.

The part of present most screwdriver levers all is designed to and the direction of screwdriver head at same axle, (as the quite tight screw of locking of outwarding winding) yet in some cases, if lever and screwdriver head have identical axial, then Cao Zuo active force is less, and it is impracticable, therefore also release the screwdriver that a kind of lever and screwdriver head have vertical angle in the market, this kind screwdriver is vertical angle because of lever and screwdriver head, the active force of operation is bigger, the tighter screw of locking of can more easily outwarding winding.But these two kinds of products are made separately at present, in use need buy two kinds of products.During if go out,, also need carry two kinds of screwdrivers simultaneously for the ease of changing mode of operation; Need to change at any time if run into different demands at work, very inconvenient for the user, and increase cost.

Therefore, the utility model main purpose is to provide a kind of hand-operated tools structure of different user modes of variable lever.

According to the disclosed hand-operated tools structure of the utility model, comprise screwdriver head, Connection Block, reach lever; Screwdriver head wherein is arranged on an end of Connection Block, lever is arranged on the other end of Connection Block movably, lever can rotate to first operating position with the screwdriver head coaxial direction, and can rotate to second operating position that becomes vertical angle with screwdriver head, and make lever remain in first operating position or second operating position at work by a locking bolt, therefore the user can be threaded to first operating position or second operating position with lever according to operational requirements, with the carrying out of handled easily.

For allowing more perspicuousness of above-mentioned and other purposes of the present utility model, feature and advantage, hereinafter will lift a preferred embodiment, and elaborate in conjunction with appended accompanying drawing.

As shown in Figure 1, comprise Connection Block 10, screwdriver head 20, lever 30, reach locking bolt 40 according to the disclosed hand-operated tools structure of the utility model.

Connection Block 10 is shaft-like haply, and its end is provided with screwdriver head 20.The head end of screwdriver head 20 can be set to yi word pattern, cross, blossom type or socket type, meets the shape and structure (not shown) of various different screws, nut.Screwdriver head 20 can be one-body molded with Connection Block 10, perhaps adopts design detachable and combination, so that change 20 operations of different screwdriver heads; In addition, pivot connection 11 of other end design at the corresponding screwdriver head 20 of Connection Block 10, pivot connection 11 has a pivotally connected hole 12 of running through, pivotally connected hole 12 2 ends are square respectively and are circular, constituting a fixed part 121 and a release portion 122, and the internal diameter of release portion 122 is greater than the diagonal angle length (as shown in Figure 4) of fixed part 121.

Lever 30 is one solid cylindric, end at lever 30 is provided with a holding tank 31, holding tank 31 has two openings 311,312 in abutting connection with direction on lever 30, and lever 30 just can be placed on the pivot connection 11 that is clipped in Connection Block 10 in the holding tank 31, wherein two inboards of holding tank 31 correspond respectively to the fixed part 121 in pivotally connected hole 12, be provided with fixing hole 313 and through hole 314 in the position of release portion 122, fixing hole 313 is corresponding to the projected square part of holddown groove 121, and through hole 314 is corresponding to the circular portion of release portion 122; In addition, be outward extended with first loose slot 315 that runs through lever 30 by fixing hole 313, first loose slot 315 is rounded, its internal diameter is greater than the catercorner length of fixing hole 313, and 314 be outward extended with second loose slot 316 that runs through lever 30 from boring a hole, second loose slot 316 is rounded, and its internal diameter is greater than the internal diameter (as shown in Figure 5) of perforation 314.

As shown in Figure 6, locking bolt 40 is rounded haply, and just can extend into the pivotally connected hole 12 of Connection Block 10 by first loose slot 315 of lever 30, and pass second loose slot 316, lever 30 is connected on the Connection Block 10 in transportable mode by means of locking bolt 40; Be provided with locating piece 41 at locking bolt 40 corresponding to the appropriate position of fixed part 121 and fixing hole 313, locating piece 41 is square, and is slightly less than fixed part 121 and fixing hole 313; Locking bolt 40 is provided with a button portion 42 at corresponding first loose slot 315 places, between button portion 42 and fixing hole 313, pack into a flexible member 50, be provided with a clip 60 in button portion 42 corresponding to the position of second loose slot 316, clip 60 is slightly larger than through hole 314, can be clamped in the position of through hole 314, make locking bolt 40 unlikely dropping out, elasticity by means of elastic component 50 makes the locating piece 41 of locking bolt 40 between fixed part 121 and fixing hole 313, can't be movable at this position lever 30, this position is the locked position of locking bolt 40; Press the button portion 42, make locking bolt 40 move inwardly into locating piece 41 and break away from fixed parts 121 and fixing hole 313 and enter release portion 122, this position lever 30 can be movable on Connection Block 10, and this position is the off-position (shown in Fig. 7 A, 7B) of locking bolt 40.

One of mode of operation that expression the utility model shown in Figure 2 provides, wherein lever 30 and screwdriver head 20 be positioned at same axially, lever 30 is called first operating position in this position, promptly is in the normal state, locking bolt 40 remains on locked position, guarantee the operation carry out in lever 30 be in first operating position; When changing another mode of operation, user's desire presses the button portion 42, make locating piece 41 disengaging fixed parts 121 and fixing hole 313 enter release portion 122, allow locking bolt 40 move to the off-position, lever 30 can be an axis rotation with locking bolt 40 promptly, because the opening 311 that the holding tank 31 of lever 30 only has two closures, 312, therefore 30 of levers have the scope of activities of 90 degree, lever 30 is moved to second operating position (as shown in Figure 3) that is vertical angle with instrument pass 20, loosen button portion 42, make locating piece 41 be returned to the position of fixed part 121 and fixing hole 313 and go into locked position by means of flexible member 50, make lever 30 be fixed on second operating position, guarantee the carrying out of operating.

, two kinds of different operating positions are provided, and need not choose two kinds of instruments according to making disclosed hand-operated tools structure according to this, and be convenient to the user and change according to need of work and be beneficial to the carrying out of operating.

The above is a preferred embodiment of the present utility model, is not to be used for limiting the novel practical range of this reality; Being that all equivalences of being done according to the utility model claims change and improvement, all is that claims of the present utility model cover.
