The specific embodiment
The purpose of this utility model provides a kind of driver bit pilot sleeve and driver bit and screwdriver thereof, belong to a kind of hardware ﹠ tools solution, solution at some such as operating distance is far away, operating environment light is bad, operator's sight line is stopped etc. that by barrier in particular cases screw unclamps and fastening inconvenience, be particularly useful for the degree of tightness operation that screw cap is slotted and is shaped as cylinder or hemispheroidal screw, reduce task difficulty, improve efficiency of operation.
As shown in Figure 3 and Figure 4, screwdriver described in the utility model includes handle 1, screwdriver rod 2 and the driver bit 3 that links to each other successively.Handle mainly is operating personnel's hand position and a direct force application part.Shown in Fig. 2 b, described driver bit includes cutter head part 11 and the center bolt cutter head heart part 12 that links to each other successively.Described cutter head heart part can be a traditional word structure, cross structure or other structure, and driver bit heart part mainly is to apply torsion to screw, finish screw unclamp or fastening.Shown in accompanying drawing 2a and 2b, the outside of described center bolt cutter head heart part 12 has pilot sleeve 13, the ratio center bolt cutter head length value that pilot sleeve inner chamber depth value need design is big, could guarantee like this when unclamping with trip bolt, pilot sleeve is enclosed within the outside of screw cap, to play guide effect and to realize that driver bit docks easily with screw.The concrete shape and size of pilot sleeve inner chamber can be according to the variation that matches of the outside true form of screw cap and size, and the pilot sleeve cavity shape can be cylindrical, hemispherical, hexagonal cylindricality or other shapes.
In the utility model, pilot sleeve and cutter head part, cutter head part and knife bar part can manufacture one, also can create independently product respectively, are mounted for one by erecting device.For example: a side of pilot sleeve has erecting device, have on the position of the cutter head of driver bit part near cutter head heart part with sleeve on the corresponding erecting device of erecting device, pilot sleeve and cutter head part are mounted for one by described erecting device.Cutter head part is provided with erecting device away from the position of cutter head heart part, knife bar near the position of cutter head be provided with the cutter head part on the corresponding erecting device of erecting device, described knife bar and described cutter head connect as one by described erecting device.
Described erecting device can be the screw thread erecting device, can be the cutting ferrule erecting device, and the erecting device that every those skilled in the art do not need creative work just can implement can adopt in the utility model.After pilot sleeve, driver bit and knife bar were provided with corresponding erecting device, the pilot sleeve of difformity and size and dissimilar driver bits be independent assortment arbitrarily, to satisfy the action need to difformity and size stud; Similarly, when pilot sleeve and driver bit are set to one, setting on the driver bit away from cutter head erecting device partly, and after knife bar is provided with corresponding erecting device, can select the driver bit of different model to be installed on the knife bar, to satisfy action need to difformity and size stud.The setting of above-mentioned erecting device has made things convenient for use widely, and has saved cost.
As shown in Figure 3, the hardware ﹠ tools screwdriver in the application example in the present embodiment is a manual cross head driver that adopts the utility model scheme.The pilot sleeve 13 of driver bit adopts cylindrical cavity, leads when realization is operated the screw with column type screw cap; Cutter head heart part 12 adopts cross head design, is used for cruciform slot screw is applied torsion; Screwdriver rod 2 connections play a part to connect cutter head 3 and handle 1 and transmit torsion; Handle 1 is operating personnel's hand position and a direct force application part, and pilot sleeve 13, driver bit part and screwdriver rod 2 are formed in one.This instrument is mainly used in unclamping with fastening of the cylindrical screw cap of solution, cruciform slot screw, as the cross recess captive screw in the accompanying drawing 1.
Shown in the accompanying drawing 4, the hardware ﹠ tools screwdriver in the Another application example in the present embodiment is a manual manifold screwdriver that adopts the present invention program.The employing cylindrical cavity of the pilot sleeve of driver bit 3 leads when being implemented in the operation of the screw of column type; The cutter head heart 12 adopts the manifold structure, is used for slotted head screw is applied torsion; Screwdriver rod 2 connections play a part to connect cutter head 3 and handle 1 and transmit torsion; Handle 1 is operating personnel's hand position and a direct force application part.Pilot sleeve 13, driver bit part and screwdriver rod 2 are formed in one.This instrument is mainly used in unclamping with fastening of the cylindrical screw cap of solution, slotted head screw, as the flat recess captive screw in the accompanying drawing 1.
In the practical application, adopt the screwdriver of the utility model organization plan to add magnetic earlier in driver bit heart part, since pilot sleeve design than in the screwdriver head length, when the needs trip bolt, can earlier screw be embedded in the pilot sleeve, and then with embedding the screwdriver of screw stretch to screw hole, screw is screwed into; When the needs unscrew, earlier find screw cap by the pilot sleeve guiding, again with screwdriver left rotation and right rotation a little, driver bit is embedded in the fluting on the screw cap, be rotated the screw that gets loose then.
Adopt the screwdriver of scheme of the present invention, compare with existing screwdriver, three advantages are arranged:
First advantage must used the operation of stock screwdriver, and staff be can't protect screw the time, Can effectively guarantee to be embedded in the unlikely landing of screw in the pilot sleeve;
Second advantage is under some particular surroundings, particularly in, operating environment far away such as operating distance In the situations such as rather dark, operator's sight line is blocked, there is visual impairment in the operator, be convenient to screwdriver Can find fast screw cap and dock smoothly with screw, make operation become possibility, and improved operating efficiency;
The 3rd advantage, carry out to screw unclamp or when fastening because the protection of pilot sleeve is arranged, Can avoid driver bit slippage from screw slots.
The 4th advantage because the pilot sleeve of single product, have pilot sleeve driver bit, with And the erecting device on the knife bar so that the pilot sleeve of difformity, size and type, driver bit and Knife bar is independent assortment arbitrarily, to satisfy the action need to the screw of difformity and size, greatly Make things convenient for the scene to carry and use, and saved cost.
Comprehensive and opinion, the pilot sleeve of this utility model, driver bit and the reasonable solution of screwdriver scheme Determined, operating environment light bad, operator sight line far away at, operating distance narrow and small such as the operating space By unclamping and fastening problem of screw in the situations such as barrier stops, reduced task difficulty, improved work Industry efficient and operation reliability are a kind of simple and effective driver bit solutions.
