Abstract
The invention relates to a wrench capable of adjusting head angles in a narrow space. The wrench capable of adjusting the head angles in the narrow space comprises a wrench head, operation handles and a locking screw rod, wherein the wrench head is movably connected with the operation handles, each operation handle is of a hollow cylindrical structure, an internal thread is arranged on the inner wall of the upper portion of each operation handle, a hemisphere is arranged at the top of the locking screw rod, an external thread is arranged on the upper portion of the locking screw rod and below the hemisphere, the external thread is matched with the internal threads on the operation handles, and the locking screw rod is connected with the operation handles in threaded mode. The wrench capable of adjusting the head angles in the narrow space can replace different wrench heads according to use conditions, and is flexible and convenient to use, wide in application range, and suitable for various devices. According to the wrench capable of adjusting the head angles in the narrow space, the operation handles are of a combination type, the adjacent operation handles are connected in threaded mode, and the length of the operation handles can be adjusted according to the use conditions.
Description
Technical field
The present invention relates to a kind of spanner, especially relate to a kind of spanner for narrow space adjustable spanner head angle.
Background technology
Existing spanner kind comprises fork spanner, combination wrenches, adjustable wrench and box spanner etc., Wrench head is relative with operating grip fixing, Wrench head can not windup-degree, and operating handle length is fixed, at narrow space, there is operating difficulties in corner or darker working environment, spanner cannot rotate, and impact uses.
Summary of the invention
The object of this invention is to provide a kind of spanner for narrow space adjustable spanner head angle, this Wrench head can windup-degree and operating grip can lengthen, and solves the situation that common spanner under various particular surroundings cannot use.
The technical solution used in the present invention is:
1, a kind of spanner for narrow space adjustable spanner head angle, it is characterized in that including driving end 1, operating grip 2 and tie down screw 3, driving end 1 is flexibly connected with operating grip 2, described operating grip 2 is open circles barrel-like structure, the inwall on operating grip 2 top is provided with internal thread 21, the top of tie down screw 3 is provided with hemisphere 31, the below that the top of tie down screw is positioned at hemisphere is provided with external screw thread 32, external screw thread matches with the internal thread on operating grip, and tie down screw is threaded with operating grip.
2, a kind of spanner for narrow space adjustable spanner head angle according to claim 1, it is characterized in that the top of described operating grip has U-shaped groove, two sidewalls of U-shaped groove have hole, and driving end 1 is connected by bolt 11 with operating grip.
3, a kind of spanner for narrow space adjustable spanner head angle according to claim 1, is characterized in that described operating grip 2 is knockdown, is threaded connection between adjacent operating grip.
The advantage that the present invention has and effect are:
1, a kind of spanner for narrow space adjustable spanner head angle of the present invention, because driving end is flexibly connected with operating grip, therefore can change different driving ends according to service condition, flexible and convenient to use, applied widely, is applicable to plurality of devices.
2, the present invention is connected with tie down screw by screw thread because operating grip is inner, the top of tie down screw is provided with hemisphere, the height of hemisphere is adjusted by screwing and unscrew the elasticity of screw thread between tie down screw and operating grip, fix dwelling in the driving end of different angles by adjusting the height of hemisphere, can be used for each narrow, have corner or darker extreme environment.Simple and convenient assembly, fast, cheap.
3, operating grip of the present invention is knockdown, is threaded connection between adjacent operating grip, can adjust the length of operating grip according to service condition.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the structural representation of tie down screw of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, 2, a kind of spanner for narrow space adjustable spanner head angle of the present invention, include driving end 1, operating grip 2 and tie down screw 3, driving end 1 is flexibly connected with operating grip 2, described operating grip 2 is open circles barrel-like structure, the inwall on operating grip 2 top is provided with internal thread 21, the top of tie down screw 3 is provided with hemisphere 31, the below that the top of tie down screw is positioned at hemisphere is provided with external screw thread 32, external screw thread matches with the internal thread on operating grip, and tie down screw is threaded with operating grip.Adjusting the height of hemisphere by screwing or unscrew tie down screw, fixing dwelling in the driving end of different angles by adjusting the height of hemisphere, thus adapt to each narrow, have corner or darker extreme environment.
The top of described operating grip has U-shaped groove, and two sidewalls of U-shaped groove have hole, and driving end 1 is connected by bolt 11 with operating grip.
Described operating grip 2 is knockdown, is threaded connection between adjacent operating grip.
Using method of the present invention is as follows:
Before using, tie down screw is mounted to operating grip inside through operating grip top, selects driving end according to required size afterwards, driving end screw is mounted to operating grip top, after being adjusted to proper angle, revolve on tie down screw, clamping driving end, spanner can use.
