Abstract
The utility model provides a screwdriver of area illumination and clamping screw device. The handle body is provided with a battery, an electric bulb, a switch, a reflector and the like to form a lighting device; the cutter bar is provided with a screw clamping sleeve, a spring, an outer pressing sleeve and the like to form a clamping screw device. The device is characterized by being suitable for working conditions of narrow working surface, difficult operation, no illumination, need of insulation and the like.
Description
The utility model belongs to hand tools, is specifically related to a kind of screwdriver with illumination and pinching screw device.
When using general screwdriver trip bolt, be one and hand-heldly hold screwdriver that another hand screw, and it is stabilized in the fastening position of need.But run into following situation in the work: or be difficult for narrow and small place or hole that hand is stretched into, or livewire work, or light according to less than shadow surface work or the like, all inconvenience is with hand-held screw and need to give the illumination of local operating position.
The purpose of this utility model is exactly in order to satisfy need of work under the above-mentioned specific environment, and a kind of screwdriver with illumination and pinching screw device is provided.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the anterior cross-sectional schematic of the utility model knife bar.
The diagram mark:

The utility model is realized by following technical proposals:
Handle body (6) at screwdriver is built-in with battery (4) and small electric bulb (5), and the bowl-shape speculum (7) and the transparent body (10) are equipped with in the front of small electric bulb (5), forms lighting device; Be equipped with screw rod gripping sleeve (13) in knife bar (11) front portion,, form clamping device by holddown spring (15) and the action of external compression cover (12) control pinching screw.
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, in screw driver handle body (6), battery (4) and small electric bulb (5) are housed.Be equipped with the battery bonnet (1) that screws by screw thread in the rear end of handle body (6), can compress and connect battery by battery spring (2).Place the switch (3) in handle body (6) outside, the controllable power break-make.The one bowl-shape speculum (7) and the transparent body (10) are arranged in the place ahead of small electric bulb (5).Be fixed on the front end face of handle body (6) by lock nut (8).The transparent body (10) and affixed being integral of knife bar (11), its inner face has pair of projections (9), and with the groove fit on the front end face of handle body (6), when making the handle rotation, knife bar (11) rotates simultaneously.The light that small electric bulb (5) sends is through bowl-shape speculum (7) and the transparent body (10) irradiation working face.More than form lighting device.As shown in Figure 2, knife bar (11) is the multidiameter shape, and there is one section external screw thread (14) centre.At cutter head (17) and external screw thread (14) interlude, the twice chute (19) of symmetric arrangement is arranged, the outside is with holddown spring (15).The outside of cutter head (17) is with screws clamp cover (13).The twice flange (16) of screws clamp cover (13) inner face symmetric arrangement can slide in chute (19) vertically, and assurance screws clamp cover (13) can not deviate from.Clamping running-on (18) at screws clamp cover (13) other end is conical surface quartering opening shape, is made by certain flexible material, and the screw of different-diameter gets final product clamping when the conical surface that clamps running-on (18) slides into the jam-packed running-on.Be with external compression cover (12) in the outside of knife bar (11), pass through threaded engagement between them.By rotation external compression cover (12), controlled screw-making gripping sleeve (13) clamps or loosens screw.When screw is clamp-oned clamping running-on (18), make it to expand distortion, external compression cover (12) moves downward vertically, and forced deformation restores to the original state, and it is tighter that screw is held.Otherwise, promptly right.
When using clamping device of the present utility model, can be earlier nut one end of screw be placed to clamp among the running-on, screw one end is stood on the plane, pressure gets final product clamp screws a little.For the screw of large-size, rotatable external compression cover (12) makes the relative knife bar (11) of screws clamp cover (13) move downward pinching screw vertically.
The utility model can be suitable for different screw job requirements by changing knife rod more.
It is can pinching screw and work under no illumination condition that the utility model has characteristics; Simple and reasonable, cost is low, easily implements, and can be used for the insulated working environment.
Claims (2)
1, a kind of screwdriver with illumination and pinching screw device, form by handle body (6), knife bar (11) and cutter head (17), it is characterized in that handle body (6) is built-in with battery (4) and small electric bulb (5), small electric bulb (5), the bowl-shape speculum (7) and the transparent body (10) are equipped with in the front of small electric bulb (5), form lighting device; Knife bar (11) front portion is equipped with screws clamp cover (13), by holddown spring (15) and the action of external compression cover (5) control pinching screw, forms clamping device.
2, according to claim 1 a kind of with the illumination and the screwdriver of pinching screw device, it is characterized in that the twice flange (16) of the inner face symmetric arrangement of screws clamp cover (13), can slip chute (19) in vertically; The outer face promptly clamps running-on (18) and is conical surface quartering opening shape, and makes by having certain flexible material.
