Abstract
The utility model relates to a kind of universal meter rod that can stretch, and belongs to machinery manufacturing technology field.The purpose of this utility model be achieved in that this universal meter rod by spring, prod, two runners, show excellent cylinder and form.It is characterized in that: spring housing in the middle of prod, for reset.The runner tooth of two band guide grooves is enclosed within prod rear end relatively, for controlling the flexible of prod.Spring, two runners, prods are contained in the excellent cylinder of table, and showing excellent cylinder inwall has part guide rails.Owing to adopting technique scheme, the advantage that the utility model has and good effect are: prevent two table rod short circuits, avoid unnecessary electric energy loss.Safety, is easy to carry.
Description
Technical field
The utility model relates to a kind of universal meter rod that can stretch, and belongs to machinery manufacturing technology field.
Background technology
At present, multimeter be all traditional non-retractable fixed table rod, when multimeter is in ohms range, red, the black two table rods put conveniently touch same conductor or directly contact and short circuit sometimes simultaneously, put the electricity that can consume battery in multimeter for a long time like this.In addition, table caput is sharper, both dangerous, also not Portable belt.
Utility model content
The purpose of this utility model is, provide a kind of can stretch universal meter rod, both safely, be easy to carry, can prevent again two tables rod short circuits, avoid unnecessary electric energy loss.
The purpose of this utility model is achieved in that when testing with multimeter, clicks the cap showing excellent rear end, and table rod is stretched.Click the cap showing excellent rear end after being completed again, make table rod pinch in.
Owing to adopting technique scheme, the utility model has advantage and good effect is: prevent two table rod short circuits, avoid unnecessary electric energy loss.Safely, be easy to carry.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is table rod, and wherein 1 is metallic member, and 6 is parts of plastics (central conductors)
7,8 of Fig. 3 is the sectional view of two runners 5 and 4 respectively, and 9 is the sectional views showing excellent cylinder band rail sections
Accompanying drawing 1 identifies
1,6, table rod; 2, excellent cylinder is shown; 3, spring; 4,5 runners (being all 6 teeth, 3 grooves)
Embodiment
Below in conjunction with the drawings and specific embodiments, structure of the present utility model is further elaborated.
As shown in Figure 1, when pressing 5, runner 4, under the promotion of 5, moves right together with table rod, make the guide groove of 4 shift out guide rail, 4,5 two gear teeth interact simultaneously, produce rotating torque, because showing guide rail in excellent cylinder all the time in the guide groove of 5, make 5 can not rotate, 4 rotate a tooth pitch.Unclamp 5, runner 4 is moved to the left to till the gear teeth are hindered by the guide rail shown in excellent cylinder under the action of the spring, and table rod stretches out.Click 5 again, runner 4 rotates a tooth pitch, and the guide rail now in the guide groove of 4 positive his-and-hers watches rod cylinder, 4 are moved to the left together under the action of the spring with table rod, and table rod is retracted.
Claims (1)
1. the universal meter rod that can stretch, by spring, prod, two runners, show excellent cylinder and form, it is characterized in that: spring housing is in the middle of prod, for resetting, the runner tooth of two band guide grooves is enclosed within prod rear end relatively, for controlling the flexible of prod, spring, two runners, prods are contained in the excellent cylinder of table, and showing excellent cylinder inwall has part guide rails.
