Description

The instrument rotating handle

Technical field

The utility model relates to a kind of instrument rotating handle.

Background technology

Generally have at present the instrument of screwdriver head, be provided with lever mostly, this lever other end then is provided with screwdriver head, and that this screwdriver head is made as is fixed, perhaps be made as separate type,, can cooperate the object dismounting such as screw of different size and shape to use for the screwdriver head of the different size that changes the outfit.But because this lever and screwdriver head are a straight line, can't be bent into other angle, when causing the dismounting screw, barrier stops arround being subjected to easily, so that dismounting smoothly, but can't change over different angles again, thus make disassemble and assemble work double difficulty, even expend considerable strength and time, finish and be difficult to dismounting.

For this reason, known techniques is as shown in Figure 7 arranged, it mainly is provided with a handle A, the end of this handle A is pivoted with a connecting rod B with axostylus axostyle A1, the other end of this connecting rod B then is provided with tool-joint B1, for affixed screwdriver head, and this connecting rod B and the handle A place that is articulated again, be provided with a card pearl B2 who is subjected to spring B 3 ejections, and handle A is provided with a draw-in groove A2 with respect to the position of this card pearl B2.

During use, as handle A and connecting rod B linearly when (0 °), card pearl B2 can be stuck in location in the draw-in groove A2, so, then can utilize connecting rod B to carry out the disassemble and assemble work of object such as screw; When desiring the different dismounting angle of conversion again, only need pull connecting rod B, the clip that makes draw-in groove A2 break away from card pearl B2 utilizes card pearl B2 to fasten in the sidewall of handle A front end, clip is located so as to reaching orthogonal (90 °), thereby angle that can be different is carried out the dismounting screw; Yet above-mentioned occupation mode is because connecting rod B only is 0 ° and 90 ° of two kinds of angles for dismounting with handle, its scope of application is quite narrow and small, when running into the object of dismounting non-0 ° or 90 °, then utterly useless at all, and the location of this connecting rod B and handle A, only rely on card pearl B2 to be subjected to the elastic force contact of spring B 3, because the resistance quantity not sufficient of spring B 3, and long-term the use down easily cause elastic fatigue, so that lost the clip effect, therefore also not satisfactory in the use.

The utility model content

The purpose of this utility model is to provide a kind of instrument rotating handle, and it can rotate relatively and be bent into different angles and location, to carry out the disassemble and assemble work of different angles.

For achieving the above object, technical solution of the present utility model is: a kind of instrument rotating handle, and it comprises handle and bending handle, and this handle one end is provided with room, and its other end is provided with the articulated section; This bending handle is articulated on the articulated section of handle, and bending handle one termination is provided with tool-joint; It further comprises clip unit and holder, is provided with the perforation that runs through handle in the room of wherein said handle, and the clip unit is established in this perforation, and clip unit one end is provided with clipping block; This holder is fixed in the room of handle, and it is provided with can be for the push rod of contact clip unit; The bending handle other end is provided with gear again, and this gear periphery ring is provided with and can supplies the clipping block clip of clip unit in draw-in groove wherein.

The push rod periphery ring of this holder is provided with groove.

The room opening part inner edge of this handle is provided with screw thread, and that the outer rim of holder is provided with screw thread relatively is fixing to be spirally connected mutually.

After adopting such scheme, the utlity model has following advantage:

1, the utility model utilizes the clipping block of clip unit movable to snap in the draw-in groove of bending handle gear, for can being positioned to various angle, thus convenient, carry out the dismounting object rapidly.

2, the utility model can be established in the groove of holder into the screwdriver head that difformity and size are arranged again, in the room that is concealed in handle, is convenient for carrying so as to reaching, does not take up space and be difficult for effect such as loss.

The specific embodiment

At first, see also shown in Figure 1ly, the utility model mainly comprises handle 1, clip unit 2, holder 3 and bending handle 4, wherein:

Handle 1, the one end is provided with a room 11, these room 11 opening part inner edges are provided with screw thread 12, this room 11 is provided with a perforation 13 that runs through handle 1 again, this handle 1 other end convexes with two relative articulated sections 14, this articulated section 14 is provided with pivot hole 15, for a pin connected assembly 16 establish into, and fixed with nut 17.

Clip unit 2 is established in the perforation 13 of handle 1, and an end of this clip unit 2 is provided with clipping block 21, is arranged with a spring 22 in addition on clip unit 2.

Holder 3, it is screwed in the room 11 that is fixed in handle 1, convexes with a push rod 31 on this holder 3, and these push rod 31 periphery rings are provided with groove 32, and the outer rim at this holder 3 is provided with screw thread 33 again.

Bending handle 4, it is articulated on the articulated section 14 of handle 1, and these bending handle 4 one terminations are provided with tool-joint 41, and the other end then is provided with gear 42, and these gear 42 periphery rings are provided with some draw-in grooves 43, run through again to be provided with a pivot hole 44 on gear 42.

During combination, as shown in Figures 2 and 3, earlier with sheathed spring 22 on this clip unit 2, and it is established in the perforation 13 of handle 1, the gear 42 of this bending handle 4 is established between two articulated sections 14 of handle 1 then, its pivot hole 44 and 15 is aligned mutually, and utilize pin connected assembly 16 to penetrate in wherein, again with nut 17 location that is spirally connected, the clipping block 21 of clip unit 2 is snapped in the draw-in groove 43 of bending handle 4 gears 42, and then in the groove 32 of holder 3, establish screwdriver head C into difformity and size, for conveniently collecting and carry, and utilize the screw thread 33 of holder 3 to be fixed in the screw thread 12 of room 11 of handle 1, so as to being fixed in

handle

1,31 pushing tows of the push rod of this holder 3 on clip unit 2, make its clipping block 21 can permanent clip in the draw-in groove 43 of gear 42.

During use, as shown in Figure 4, can utilize in the tool-joint 41 of this bending handle 4 and establish, and can rotate handle 1 in order to objects such as dismounting screw D into screwdriver head C.

Again in the time need being bent into different angles with objects such as dismounting screw D, as shown in Figure 5, can unscrew the screw thread 33 of holder 3 earlier, it is withdrawed from the room 11 of handle 1, so that the push rod 31 of holder 3 pushing tow clip unit 2 no longer, the clipping block 21 of clip unit 2 is withdrawed from the draw-in groove 43 of bending handle 4 gears 42, bending this moment handle 4 can pivot on the articulated section 14 of handle 1, when rotating, can be interrupted by gear 42 pushing and pressing clipping block 21 with compression spring 22, thereby form a snap action intermittently, bending handle 4 and handle 1 can be rotated be folded into optimum angle, and then holder 3 screwed again, make in its room that is fixed at handle 1 once again 11, so as to the push rod 31 pushing tow clip unit 2 that make holder 3, make its clipping block 21 can clip in the draw-in groove 43 of gear 42, and then bending handle 4 and handle 1 are maintained fixed bend in suitable angle, with as shown in Figure 6, can carry out objects such as dismounting screw D.
