Abstract
The telescopic tool handle has hollow fixed rod and movable rod inserted in the front end of the fixed rod, and the tool head is fixed to the front of the movable rod. The fixed rod has slot and fixing head in the front end and sliding sleeve in the middle part; the movable rod has buckle and extends from the slot of the fixed rod; the fixing head has pulley and one thin steel cable has one end fixed onto the sliding sleeve and the other end fixed onto the buckle after passing around the pulley. The present invention has the advantages of being used in narrow space, light weight, great force, etc.
Description
Technical field
The application relates to tool handle, relates in particular to pick hammer class toolholder.
Background technology
With instruments such as pick, hammer ram classes, since history, the full-length size of its handle all about 1m, fix by length in industrial and agricultural production, and material is based on wooden.Many inconvenience are arranged in produce using: as run into little working space (as tunnel, tunnel, irrigation canals and ditches etc.) and stretch not open, do not use power; As run into harder, solid or greatlyyer when pounding power, seem that again handle strength is not enough.Suppose this handle longly, but the people need make fulcrum when lifting instrument on the other hand, and on the other hand at handle one end firmly, fulcrum is too near by tool heads, raises lightly, is not easy to firmly but the distance of two hands is too far away; Fulcrum is far away by tool heads, though the position of two hands suitably lifts not come.Therefore, be sought after a kind of tool handle of automatic adjustment fulcrum, solve the use inconvenience problem of existing long admittedly handle instrument.
Summary of the invention
The application's purpose provides a kind of telescopic tool handle, solves the use inconvenience problem of existing long admittedly handle instrument.
Technical scheme is: it is to insert one section motion bar at hollow fixed bar front end, the fixing tool heads that goes up of motion bar front end, the fixed bar front end has groove and is with fixedly head, slip cap is arranged in the middle of the fixed bar, fixingly on the motion bar go up the attacker and from the groove of fixed bar, expose, on fixing head pulley (or slip ring) is arranged, a seizing wire one end is fixed on the slip cap, the other end is fixed on the attacker after walking around pulley.
Use principle and method are: at first people one holds the fixed bar tail, tool heads places ground, make in the motion bar retraction fixed bar class, one holds movable sleeve, forefinger just in time fastens the attacker simultaneously, and the motion bar tension can not be deviate from, and whole handle shortens, because the movable sleeve position is a fulcrum and near tool heads, instrument can be lifted gently place shoulder after.The openhanded attacker of opening who holds movable sleeve afterwards slides to holding the fixed bar tail, promptly two hands are close, at this moment, under the drive of thin steel rope, tool heads is stretched out from motion bar, and away from the first segment distance of instrument, the radius of turn that tool heads is fallen is elongated again for fulcrum, increased acceleration and linear velocity, hit energy thereby increased the energy that lands greatly or pounded.
In the application's the scheme, can make of stainless steel tube, in order to increase the suitable sense of hand and frictional force and shock resistance, the shockproof anti-sliding sleeve of plastics elasticity on fixing on the hand-holding part of fixed bar rear end and the slip cap.If hammer ram can increase by one section spring between motion bar and tup, alleviate the hand shake.
The application's good effect is: when 1, running into small space, in the motion bar indentation fixed bar, by the bolting on the reducing head together, handle is shortened, be convenient to operation.2, run into hard or when pounding power more greatly, handle is extended automatically, this lengthening is to finish simultaneously in operation, and light when lifting, power is big when falling, if 3 when being used for hammer ram, increases damping spring, has avoided the vibrations of people's arm wrist injured.
Description of drawings
Fig. 1 is the application's a front view, the situation when having represented elongation among the figure; Fig. 2 is the application's a vertical view, the situation when having represented among the figure to shorten; Fig. 3 is the structure chart that increases by one section spring when being used for the handle of hammer ram.
Among the figure: 1-tail cover, the hollow fixed bar of 2-, the 3-slip cap, the 4-seizing wire, the 5-motion bar, the 6-groove, the 7-attacker, the 8-pulley, the 9-hold-down screw, the 10-tool heads, 11-is head fixedly, the 12-spring.
The specific embodiment
As shown in Figure 1 and Figure 2, first half at hollow fixed bar 2 has groove 6, first half inserts motion bar 5, with fixing 11 fixing, be with slip cap 3 on the fixed bar 2, fixingly on the motion bar 5 go up attacker 7, and from groove 6, expose, on fixing 11 pulley 8 is arranged, seizing wire 4 is walked around pulley 8, two ends are separately fixed on attacker 7 and the slip cap 3.Antiskid, shock-absorbing in order to operate overlaps flexible tail cover 1 at fixed bar 2 tail ends.On fixing 11, also have hold-down screw 9, when being used for tool heads 10 and not needing to stretch out it is pinned.
Embodiment as shown in Figure 3 at the fixing upper spring 12 of motion bar 5 front ends, is fixed on the hammer ram head on the spring 12.
When implementing, in order to protect seizing wire 4 not to be damaged and whole handle attractive in appearance, can add U type protective cover, with seizing wire 4 and groove 6 covers get up (not drawing among the figure) at groove 6 positions of fixed bar 2.
Claims (3)
1, a kind of telescopic tool handle, it is characterized in that, it is to insert one section motion bar at hollow fixed bar front end, the fixed bar front end has groove and is with fixedly head, slip cap is arranged in the middle of the fixed bar, fixingly on the motion bar go up the attacker and from the groove of fixed bar, expose, on fixing head, pulley is arranged, one seizing wire, one end is fixed on the slip cap, and the other end is fixed on the attacker after walking around pulley.
2, telescopic tool handle as claimed in claim 1 is characterized in that being fixed with spring at the front end of motion bar, and the hammer ram head is fixed on the spring.
3, telescopic tool handle as claimed in claim 1 is characterized in that groove (6) position of fixed bar is added with " U " type protective cover.
