Abstract
A chain driven wrench is composed of a sleeve head (1), a transmission and a handle (8). The sleeve head is installed at the front portion of a chain box (7), an output chain wheel (3) is arranged on the power output shaft (2) connected with the sleeve head, and the chain wheel is connected with an input chain wheel (9) arranged on a power input shaft (5) through a chain (4). The handle (8) is arranged at the rear portion of the chain box. The chain driven wrench transfers power from one end to the end of the sleeve head through the chain, and the distance between a force exerting point to the sleeve head is increased, so that operation can be still operated under the situation that an operation space is relatively narrower. The tightening action of the chain driven wrench is achieved in a rotary mode, and the requirement for a wrench space is reduced. The chain driven wrench is simple in structure, convenient to operate and good in applicability.
Description
Technical field
The present invention relates to a kind of small tool, is a kind of Chain conveyer spanner specifically.
Background technology
Along with the fast development of mechanical industry, engineering goods are just towards Highgrade integration future development, and the assembling between parts is compacter, tight, and this is just more and more higher to the performance requirement of assembly tool.Traditional bolt or fastening nuts spanner are all made up of pullover and handle, and by the restriction of operating space, the bolt at some special construction place or nut come fastening very difficult with it, are even difficult to realize.The present invention is exactly for this situation, a kind of Novel socket wrench of development, and this spanner can when common spanner operating difficulties, has carried out tightening or loosening of bolt or nut.
Summary of the invention
The object of the present invention is to provide a kind of Chain conveyer spanner, it rotates by the termination of manual or electronic drive one end, the pullover rotation can done in the same way of spanner of the other end, can when common wrench operating difficulties maybe cannot operate by hex bolts or fastening nuts or unclamp.This spanner structure is simple, and easy to use, operating efficiency is high.
Technical scheme of the present invention is as follows:
A kind of Chain conveyer spanner, it is made up of collet head, transmission device and handle; Collet head is contained in the front portion of chain cover, and output chain gear established by the connected power output shaft of collet head, and this sprocket wheel connects input sprocket set on power input shaft through chain; Handle is established at the rear portion of chain cover.
Above-mentioned collet head is connected on power output shaft side's tenon, can change different collet heads according to different bolts, nut.
Input sprocket on above-mentioned power input shaft is close or identical with the output chain gear number of teeth on power output shaft.
Chain cover is stretched out in one end of above-mentioned power input shaft.
By adopting Chain conveyer, common wrench pulled the rotational action that collet head is changed in action, whole spanner need not be pulled, and by lengthening the distance between power shaft and output shaft, the action of input is transferred to relatively spacious place, operating space.
The invention has the advantages that: 1, power is delivered to sleeve head end by one end by chain by this device, add the distance of the point of application to collet head, increase operating distance, like this when operating space is relatively narrow and small, still can carry out operation.2, the action of tightening of this device is realized by rotation mode, is not to realize by pulling pinch bar mode, and this also reduces the requirement to spanner space from another angle.3, this apparatus structure is simple, and easy to operate, applicability is strong.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention sectional structure chart;
Fig. 2 is the A--A direction view of Fig. 1.
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In figure, 1, collet head; 2, power output shaft; 3, output chain gear; 4, chain; 5, power input shaft; 6, axle sleeve; 7, chain cover; 8, handle; 9, input sprocket.
Detailed description of the invention
Can be seen by Fig. 1 and Fig. 2, chain cover (7), axle sleeve (6), handle (8) weld together; Power input shaft (5), input sprocket (9) weld together; Power output shaft (2), output chain gear (3) weld together.Power input shaft (5), power output shaft (2) rotate in axle sleeve (6), collet head (1) is enclosed within power output shaft (2) square tenon, can change different collet heads (1) according to different bolts, nut.Input sprocket (9) on power input shaft (5) is connected with the output chain gear (3) on power output shaft (2) by chain (4).Power that is artificial or electric hand drill drives power input shaft (5) to rotate, by input sprocket (9) chain (4) transmission, output chain gear (3) and power output shaft (2) is driven to rotate, collet head (1) is driven to rotate, by bolt, nut or unclamp.This spanner will be pulled action and change rotational action into, decrease the operating space needed for spanner.The chain length of this device and two centre of sprocket are apart from increasing and decreasing according to actual needs in manufacturing process.
Claims (4)
