Abstract
The utility model discloses a kind of U-shaped pin and tear the instrument of pulling out open, comprise handle, handle front end is connected with cam by ratchet, and cam front end is provided with crotch.A kind of U-shaped pin of the utility model tears the instrument of pulling out open, and handle extracts U-shaped pin by pawl wheel cam, in space-constrained situation, repeatedly can stir ratchet, extract U-shaped pin gradually, also can movable support bar or padded base, is extracted by U-shaped pin.What efficiently can complete U-shaped pin tears the work of pulling out open, time saving and energy saving, has very large use value and market prospects.In addition, this apparatus structure is simple, and cost is low, easy to use.
Description
Technical field
The utility model belongs to flight-line maintenance equipment technical field, relates to a kind of U-shaped pin and tears the instrument of pulling out open.
Background technology
In machinery, pin is mainly used as assembling and positioning, also can be used as connecting, the overload loosened in level security device cuts off connection.Wherein, U-shaped pin, due to convenience and high-efficiency, is widely used in the pressure pipe fitting of colliery, and U-shaped pin can ensure that in use portion departs from, but there is the problem of dismounting difficulty, does not also have on the market at present to tear the instrument pulled out open for U-shaped pin specially.
Utility model content
The purpose of this utility model is to provide a kind of U-shaped pin to tear the instrument of pulling out open, solves U-shaped pin and tears the problem of pulling out difficulty open.
The technical scheme that the utility model adopts is: a kind of U-shaped pin tears the instrument of pulling out open, comprises handle, and handle front end is connected with cam by ratchet, and cam front end is provided with crotch.
Feature of the present utility model is also:
Handle is connected with base by support bar.
Base contacts with crotch.
The length of handle is 250mm-450mm.
The beneficial effects of the utility model are: a kind of U-shaped pin of the utility model tears the instrument of pulling out open, and handle extracts U-shaped pin by pawl wheel cam, in space-constrained situation, repeatedly can stir ratchet, extract U-shaped pin gradually, also can movable support bar or padded base, U-shaped pin is extracted.What efficiently can complete U-shaped pin tears the work of pulling out open, time saving and energy saving, has very large use value and market prospects.In addition, this apparatus structure is simple, and cost is low, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of U-shaped pin of the utility model tears the instrument of pulling out open.
In figure, 1. handle, 2. support bar, 3. base, 4. ratchet, 5. crotch, 6. cam.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of U-shaped pin tears the instrument of pulling out open, as shown in Figure 1.Comprise handle 1, handle 1 front end is connected with cam 6 by ratchet 4, and cam 6 front end is provided with crotch 5, and handle 1 is connected with base 3 by support bar 2, and base 3 contacts with crotch 5, and the length of handle 1 is 250mm-450mm.
During use, U-shaped pin is caught on crotch 5, downward driving handle 1, ratchet 4 on handle 1 pulls out tooth and slips over the ratchet gear teeth be fixed on cam 6, then U-shaped pin is extracted, if do not extracted, the position of removable support bar 2 or padded base 3 continue to press down handle 1, until extracted by U-shaped pin.
A kind of U-shaped pin of the utility model tears the instrument of pulling out open, and handle extracts U-shaped pin by pawl wheel cam, in space-constrained situation, repeatedly can stir ratchet, extract U-shaped pin gradually, also can movable support bar or padded base, is extracted by U-shaped pin.What efficiently can complete U-shaped pin tears the work of pulling out open, time saving and energy saving, has very large use value and market prospects.In addition, this apparatus structure is simple, and cost is low, easy to use.
