Abstract
The utility model discloses a wrench with a handle adjustable in length. The wrench comprises a handle sleeve, an adjusting rod, a first sleeve ring groove, a third sleeve ring groove, a radial hole, a second sleeve ring groove, positioning balls and a compression spring, wherein the front end of the handle sleeve is provided with a wrench head, the first sleeve ring groove, the second sleeve ring groove and the third sleeve ring groove are the same and are sequentially arranged in a hollow cylinder on the rear portion of the handle sleeve in the radial direction, the adjusting rod is arranged in the handle sleeve and is in clearance fit with the hollow cylinder of the handle sleeve, the radial hole is formed in the front portion of the adjusting rod in the radial direction, the compression spring is vertically arranged in the radial hole, and the two positioning balls are arranged on the two sides of the compression spring in the radial hole respectively. According to the wrench with the handle adjustable in the length, when the wrench is used, the length of the handle can be adjusted through adjustment of the length of the adjusting rod extending out of the handle sleeve, and the novel wrench is not like a sleeve which is easy to fall off and harmful to the human body.
Description
Technical field
The utility model relates to a kind of spanner of adjustable handle length.
Background technology
At present, when the industries such as chemical industry, metallurgy, generating, shipbuilding, machinery were carried out the valve switch operation, adopted was nonstandard F type spanner more.But because valve size is different, existing pinch bar length commonly used has 200 to 1200 not wait, because structure is fixed, tricks is more, carries and put in order all very inconvenient.Especially often use long steel pipe to be placed on the valve handle the operation site operating personnel and carry out valve operation as boosting-rod, not only inconvenient operation, and sleeve pipe easily comes off, and the person is had injury, has very large potential safety hazard.
Summary of the invention
The utility model is for the proposition of above problem, and the spanner of a kind of adjustable handle length of research and design is fixed in order to solve the existing spanner structure that uses, and tricks is more, carries and put in order all very inconvenient shortcoming.The technological means that the utility model adopts is as follows:
A kind of spanner of adjustable handle length comprises: handle jacket, adjusting lever, sleeve cannelure one, sleeve cannelure three, radial hole, sleeve cannelure two, location ball, Compress Spring; Described handle jacket front end is provided with Wrench head, the hollow cylinder at described handle jacket rear portion is inner, radially be provided with successively identical sleeve cannelure one, sleeve cannelure two and sleeve cannelure three, described handle jacket inside is provided with adjusting lever, the hollow cylinder matched in clearance of described adjusting lever and handle jacket, described adjusting lever front portion radially is provided with a radial hole, vertically be provided with Compress Spring in the described radial hole, the Compress Spring both sides respectively are provided with a location ball in the described radial hole, ball slides into sleeve cannelure one when the location, one position in sleeve cannelure two and the sleeve cannelure three, described location ball is spring force by compression, with sleeve cannelure one, fix for one in sleeve cannelure two and the sleeve cannelure three, when the push-and-pull adjusting lever, the location ball is subject in the handle jacket inner wall pressure retraction radial hole.
Distance as three of the distance of preferred described sleeve cannelure one and two of sleeve cannelures and sleeve cannelure two and sleeve cannelures is identical.
Pass the axle center of handle jacket as preferred described radial hole.
As the diameter of the preferred described location ball diameter less than radial hole, the diameter of described location ball is greater than the width of sleeve cannelure one, sleeve cannelure two and sleeve cannelure three.
Compared with the prior art, the length of handle when the spanner of a kind of adjustable handle length described in the utility model can be adjusted use by the length that the adjusting adjusting lever stretches out in handle jacket, easy coming off has injury to the person unlike sleeve pipe.Can carry out light, safe operation to different valves, and greatly reduce the apparent size of spanner, be convenient for carrying and put in order, be a kind of Novel socket wrench.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram at the radial hole position on the utility model adjusting lever.
The specific embodiment
As depicted in figs. 1 and 2, a kind of spanner of adjustable handle length comprises: handle jacket 1, adjusting lever 2, sleeve cannelure 1, sleeve cannelure 34, radial hole 5, sleeve cannelure 26, location ball 7, Compress Spring 8; Described handle jacket 1 front end is provided with Wrench head, described Wrench head is used for fixing valve handle, the hollow cylinder at described handle jacket 1 rear portion is inner, radially be provided with successively identical sleeve cannelure 1, sleeve cannelure 26 and sleeve cannelure 34, be used as the parts of fixed adjustment bar 2, described handle jacket 1 inside is provided with adjusting lever 2, the hollow cylinder matched in clearance of described adjusting lever 2 and handle jacket 1, make when not being subjected to external force, described adjusting lever 2 can be radially mobile in handle jacket 1, described adjusting lever 2 front portions radially are provided with a radial hole 5, the described radial hole 5 interior Compress Springs 8 that vertically are provided with, described Compress Spring 8 can be given an outside power of object of pressing thereon, described radial hole 5 interior Compress Springs 8 both sides respectively are provided with a location ball 7, ball 7 slides into sleeve cannelure 1 when the location, one position in sleeve cannelure 26 and the sleeve cannelure 34, described location ball 7 is spring 8 elastic force by compression, with sleeve cannelure 1, fix for one in sleeve cannelure 26 and the sleeve cannelure 34, when push-and-pull adjusting lever 2, location ball 7 is subject in the handle jacket 1 inner wall pressure retraction radial hole 5, and described adjusting lever 2 can be radially mobile in handle jacket 1 easily.
The distance that the distance of described sleeve cannelure 1 and 26 of sleeve cannelures and sleeve cannelure 26 and sleeve cannelure are 34 is identical.Described radial hole 5 passes the axle center of handle jacket 1.The diameter of described location ball 7 is less than the diameter of radial hole 5, and the diameter of described location ball 7 is greater than the width of sleeve cannelure 1, sleeve cannelure 26 and sleeve cannelure 34.
During use, when the operation large size valve, need long operating grip, at this moment, pulling adjusting lever 2, under this motive force, the Compress Spring 8 that is installed in adjusting lever 2 radial holes 5 is compressed, and location, both sides ball 7 is pushed back by the liner ring inwall in the radial hole 5 of adjusting lever 2, when adjusting to certain corresponding length, location ball 7 moves to sleeve cannelure 1, a position in sleeve cannelure 26 or the sleeve cannelure 34, locate ball 7 this moment under the promotion of the spring force of Compress Spring 8, enters in the groove, and adjusting lever 2 positions are fixed, if need to continue to add long handle, continue pulling adjusting lever 2.When operation valvelet or arrangement were put, pinch bar length needn't be long, and can push adjusting lever 2 handle jacket 1 penetralia this moment.
