Abstract
The invention discloses a handcart circuit breaker grounding switch on-off ratchet wheel type operation tool. The operation tool of the invention comprises a ratchet wheel, a ratchet pawl, a bracket and a wheel axle; the wheel axle is fixed at the center of the ratchet wheel; a non-rotating hole is formed at the center of one side of the wheel axle which is located at the ratchet wheel and is connected with a handcart circuit breaker grounding switch; the other side of the wheel axle, which is located at the ratchet wheel, is rotatably connected with the bracket; the bracket rotatably sleeves the wheel axle; the ratchet wheel comprises a ratchet wheel body and two groups of ratchet teeth arranged on the ratchet wheel body; the two groups of ratchet teeth are distributed at the outer periphery of the ratchet wheel body; the locking directions of the two groups of ratchet teeth are opposite to each other; the ratchet pawl is rotatably arranged on the bracket; when the bracket sleeves the wheel axle, the ratchet pawl is matched with one group of ratchet teeth; and when the bracket reversely sleeves the wheel axle, the ratchet pawl is matched with the other group of ratchet teeth. According to the handcart circuit breaker grounding switch on-off ratchet wheel type operation tool of the invention, the two groups of ratchet teeth of which the locking directions are opposite to each other are arranged on the same wheel body, wherein one group of ratchet teeth is used for the switching off of the handcart circuit breaker grounding switch, and the other group of ratchet teeth is used for the switching on of the handcart circuit breaker grounding switch, and therefore, operation is convenient.
Description
Technical field
The present invention relates to a kind of electric power tool, particularly a kind of handcart circuit breaker grounding switch divide-shut brake ratchet-type operation tool.
Background technology
Handcart circuit breaker grounding switch does not have automatic divide-shut brake instrument, and handcart circuit breaker grounding switch needs workman to operate by conventional tool such as spanners when divide-shut brake, wastes time and energy.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of easy to operate handcart circuit breaker grounding switch divide-shut brake ratchet-type operation tool.
In order to solve the problems of the technologies described above, the present invention includes ratchet, ratchet, support and wheel shaft, wheel shaft is fixed on the center of ratchet, there is non-rotating body opening at the center, side that wheel shaft is positioned at ratchet, for being connected with handcart circuit breaker grounding switch, the opposite side that wheel shaft is positioned at ratchet is connected with holder pivots, holder pivots is socketed on wheel shaft, ratchet comprises ratchet wheel body and is arranged on two groups of ratchets on ratchet wheel body, two groups of ratchets distribute on the cylindrical of ratchet wheel body, the stop direction of two groups of ratchets is contrary, ratchet rotates and is arranged on support, when support casing is on wheel shaft, ratchet is with wherein one group of ratchet is suitable, when support is oppositely enclosed within wheel shaft, ratchet and another to organize ratchet suitable.
The invention has the beneficial effects as follows: the present invention is provided with the ratchet of two kinds of contrary braking directions on same wheel body, one group is used for opening a sluice gate of handcart circuit breaker grounding switch, and one group of combined floodgate for handcart circuit breaker grounding switch is easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, the first ratchet, 2, ratchet wheel body, the 3, second ratchet, 4, ratchet, 5, bearing pin, 6, support, 7, wheel shaft.
Embodiment
