Abstract

The utility model relates to a semi-automatic electroprobe screwdriver which is composed of a rotating handle with an end closure and a clamp ring, a transmission device with a reversal knob, a spindle sleeve with a magnetic block and a shaft of an insulating bush, which are connected into integration, wherein, the transmission device is a whole body composed of a ratchet wheel and a shaft and is installed in a supporting frame; a ferrule with steel balls is fixed on the supporting frame which is formed by being connected with two clamping slices and matched with the reversal knob and a spring slice on a casing, and an electroprobe device formed by that a photoelectric tube with a contact strip is connected with a resistor with a contact strip and then is connected with a conducting ring is arranged on a built-in frame in the rotating handle. The utility model has the advantages of compact structure, multiple functions on one tool and convenient operation.

Description

Semi-automatic electroprobe screwdriver

The utility model relates to a kind of hand-operated tools, be suitable for fastening various securing member especially, can be used for crosshead, the screwing or unclamp of different securing members such as manifold by the various rotating tool head of conversion, and have the voltage test pencil function, can deposit the semi-automatic electroprobe screwdriver of rotating tool head.

The patent No. 98209249.0 " the spiral ratchet screw revolves tool " also provides a kind of and can deposit rotating tool head, by the conversion rotating tool head can a tool how with, the tool that revolves easy to use, but it has with generally using always and revolves different shape of tool and method of operating, and price is more expensive.

The purpose of this utility model is to provide a kind of can deposit rotating tool head, can the many usefulness of a tool by the various rotating tool heads of conversion, and have voltage test pencil function, easy to use, semi-automatic electroprobe screwdriver that price is lower.

The utility model is achieved in that semi-automatic electroprobe screwdriver is by swing handle that has end cap, clamp ring and the transmission device that has the button that commutates, the axle that has axle sleeve, the insulation sleeve of magnetic patch connects into whole the composition, and transmission device is an integral body by ratchet with axle, be placed in the support, go back the lasso of fixed band steel ball on the support and be connected with two cards and cooperate with the commutation button, the spring leaf that put outward form, in the swing handle built-in goes up the photoelectric tube that also has by the band contact chip and is connected the electroprobe device that connects and composes with conductive ring with the resistance of being with contact chip again.

Fig. 1. structural representation of the present utility model;

Fig. 2. the A-A view of Fig. 1;

Fig. 3. the B-B view of Fig. 1;

Fig. 4. the C of Fig. 1 is to view (view after taking away commutation button, spring leaf).

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

There are external screw thread and groove and through hole in the two ends of swing handle (13), have a waist through hole to cooperate with photoelectric tube (18) on the surface wall.

Six blind holes are arranged on one end face of built-in (14), be used to deposit rotating tool head, the centre has a long open slot to be used to lay photoelectric tube (18), end is cylinder in addition, lay resistance (11), the through hole of holding cylinder to communicate with other is arranged at the open slot bottom, is used to pass contact chip (12).

Overcoat (8) is the cylindrical shape that an end has edge and buckle, has the toothed through hole in a microscler edge to cooperate with commutation button (21) on the surface wall.

Card (20) is a sheet, be circular arc in the middle of the end, and to be vertical pin match with tooth on the ratchet (7) end in addition.

Support (6) is a cylindrical shape, and there is an opening upper end of mid portion, has two cascaded surfaces to cooperate with card (20) on the tube wall on opening both sides respectively.

Ratchet (7) is an integral body with axle (3), stretches in the support (6), at support (6) one end inwalls and hold on the outer wall respectively fixedly lasso (9) and insulated ring (23) in addition.Be connected with pad (24) and clasp (5) on support (6) inwall of insulated ring (23) end, one end of axle (3) is fastened with insulation sleeve (4) and axle sleeve (2), the bottom of axle sleeve (2) opening part is fixed with magnetic patch (1), and the in addition end of axle (3) and lasso (9) and interior ball (18) thereof cooperate, and swing handle (13) is fastened on the end of support (6).Go up installation photoelectric tube (18) built-in (14), resistance (11) and fixed contact piece (12) betwixt, end in addition at photoelectric tube (18) connects contact chip (17), built-in (14) assembling are fastened on the inwall of swing handle (13), two cards (20) that connect symmetry at the two ends of ratchet (7) respectively, put overcoat (8) again, buckle on it is anchored to groove fix tightly on the swing handle (13), again will be with the commutation button (21) of spring leaf (22), be installed on the overcoat (8), and be connected with card (20), two ends of thread at swing handle (13) connect conductive ring (15) respectively, end cap (16) and clamp ring (19), and the through hole that contact chip (17) is passed on the swing handle (13) is connected with conductive ring (15), and semi-automatic electroprobe screwdriver is assembled into.

During use, stir commutation button (21) in the direction of arrows, at this moment the spring leaf on it (22) is just pushed down a card (20) on the right, a card (20) on the left side obtains because of an end wing of spring leaf (22) rises discharging, then ratchet (7) but rotate and screw securing member with regard to clockwise direction, opposite ratchet (7) just counterclockwise rotates and loosening fasteners.Can make simultaneously voltage test pencil again and use, if tested thing is charged, photoelectric tube (18) conducting, luminous.

The utility model is compared with prior art: this screwdriver structure compactness, the cavity that revolves in the handle obtain fully Utilize, in order to deposit branched rotating tool head and electroprobe device, make a tool multiplex, transmission structures simply, only Stir the commutation button and make the card in two cards decontrol ratchet, another card just rotates with ratchet and tightens Or loosening fasteners, easy to use, reliable.
