Abstract

The utility model discloses a power assisted wrench, which structurally comprises a worm gear and a worm matched with each other. A socket wrench inner square joint is arranged in the worm gear, the worm is connected with a driving device through a transmission part connected to the shaft end of the worm, and the transmission part connected with the worm is a flexible shaft. A flexible shaft sleeve covers the flexible shaft outside. The driving device is a rocker or a motor. The worm power assisted wrench with the flexible shaft is laborsaving when being used for removing bolts, an operating rotating position can be shifted, while operating direction can be changed, and accordingly efficacy of removing bolts from a narrow space can be increased.

Description

A kind of Spanner with aid
Technical field
The utility model relates to spanner, specifically a kind of Spanner with aid.
Background technology
Along with the continuous development of science and technology, the continuous application of new material, the structure of equipment is compact gradually, the space of equipment component installation site is narrow and small, the anglec of rotation of common wrench is restricted, and the situation that the staff does not use power appears in the bolt position that also has, so the bolt disassembly inconvenience.
Certainly the labour-saving spanner that has had a lot of worm and gears in the reality, but the problem that they solve all is laborsaving, so the problem of assembling-disassembling bolt not solution at all easily in small space.
The utility model content
(1) technical problem that will solve
The purpose of this utility model is the defective that exists at prior art, and a kind of Spanner with aid is provided, and uses the worm gear Spanner with aid of band flexible axle can allow staff's bolt of dismounting small space easily.
(2) technical scheme
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Spanner with aid, and its structure comprises the worm and gear that is combined together, and square joint in the box spanner is arranged in the worm gear, and the driving member that worm screw connects by axle head connects drive unit; The driving member of described connection worm screw is a flexible axle.
The described flexible axle outside is enclosed with flexible shaft protecting.
Described drive unit is rocking bar or motor.
(3) beneficial effect
A kind of Spanner with aid of the present utility model is compared with prior art, has following beneficial effect:
Can be laborsaving when the utility model uses the worm gear Spanner with aid assembling-disassembling bolt of being with flexible axle, operation position of rotation dress can be moved, and can change direction of operating.Improve small space bolt disassembly effect.
1. when rotating with worm gear, the characteristics that worm gear is bigger than distance with the rotatory force of worm screw, the worm gear Spanner with aid of development, it is laborsaving to reach assembling-disassembling bolt.
2. flexible shaft line can be connected with the worm screw of Worm-wheel wrench as narrow space, during assembling-disassembling bolt, can rotate the axle of flexible shaft line outside, drive worm screw and rotate, worm screw drives the sleeve that is installed on the worm gear and rotates light assembling-disassembling bolt.
3. rotary flexible shaft drives the worm gear rotation, and the worm gear drives box spanner rotates, the bolt of light dismounting small space, and flexible axle can change operative orientation arbitrarily.
Description of drawings
Accompanying drawing is the structural representation of a kind of Spanner with aid of the present utility model.
Among the figure: 1. socket wrench adapter; 2. worm gear; 3. worm screw; 4. flexible shaft protecting; 5. flexible axle; 6. rocking bar.
The specific embodiment
Next explain below with reference to Figure of description a kind of Spanner with aid of the present utility model being done.
A kind of Spanner with aid, its structure comprises the worm and gear that is combined together, and socket wrench adapter 1 is arranged in the worm gear 2, and the driving member that worm screw 3 connects by axle head connects drive unit; The driving member of described connection worm screw is a flexible axle 5.The described flexible axle outside is enclosed with flexible shaft protecting 4.Described drive unit is rocking bar 6 or motor.What present embodiment adopted is rocking bar, as shown in the figure.
Can disassemble and use flexible shaft line or organize cross flexible axle phase continuous cropping power transmission shaft of flexible axle wherein more.When adopting worm-drive, the characteristics that worm gear is bigger than distance with the rotatory force of worm screw, development worm gear Spanner with aid utilizes flexible shaft line to make power transmission shaft, drives worm and wormwheel and rotates, and is implemented in the purpose of the light assembling-disassembling bolt of small space
Direction of rotation machining worm wheel and worm screw according to moment ratio and worm gear, and the end on worm gear and worm screw is processed into the interior coupling general with box spanner respectively, add the interlock position sealing of shell with worm gear and worm screw, the interior coupling general with box spanner is processed at flexible shaft line two respectively.
The above embodiment is a kind of of the more preferably concrete embodiment of the utility model, and common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.

Claims (3)

1. Spanner with aid, its structure comprises the worm and gear that is combined together, and square joint in the box spanner is arranged in the worm gear, and the driving member that worm screw connects by axle head connects drive unit; It is characterized in that: the driving member of described connection worm screw is a flexible axle.
2. a kind of Spanner with aid according to claim 1 is characterized in that: the described flexible axle outside is enclosed with flexible shaft protecting.
