Description

Ratchet device

Technical field

The utility model relates to it is a kind of be available for users to it is convenient switch force direction by holding the lateral rotation steering ring of seat, To avoid in compress force operating process in accidentally interlock commutation, and then be conducive to quiet run and promoted ease of use ratchet Device.

Background technique

Now, user mostly uses greatly the hand held ratchet device of small volume when assembling and disassembling the bolt tool of small article, And used with hand held ratchet device collocation one power tool (such as sleeve), user system holds hand held ratchet dress with hand Set, and with palm compress the hand held ratchet device top and the operation that exerts a force, make hand held ratchet device drive power tool Execute bolt tool assembly and disassembly operation.

Fig. 1, Fig. 2 are please referred to, is the schematic diagram of hand held ratchet device 10, is that the inside for holding seat 11 one is equipped with accommodating Slot 111, and it is equipped with inner ring ratchet 112 in the inner ring surface of accommodation groove, the mounted inside of a control ontology 12 has the clip of tool latch Block 13, and first end be equipped with one can directly control clipping block 13 deviate actuation steering turntable 14, be then equipped in second end One is in the socket column 121 of quadrangular prism, and to be socketed one as the power tool (not shown go out) of sleeve, which is placed in The accommodation groove 111 of seat 11 is held, enables socket column 121 protrude out this and holds the bottom surface of seat 11, and engage the side latch of clipping block 13 The inner ring ratchet 112 of seat 11 is held, and steering turntable 14 then protrudes from the top surface for holding seat 11, so that user operates switching force side To, then the control limit of ontology 12 is assembled in retaining ring 15 and holds seat 11；In in use, 10 system of ratchet device to control ontology 12 Socket one sleeve of collocation of socket column 121 (not shown go out) use, small in size due to ratchet device 10, the hand of user can Hold ratchet device 10 holds seat 11, and is compressed with palm and be located at the steering turntable 14 for holding 11 top surface of seat, and force operates this and holds Seat 11 rotates, and is rotated synchronously with the socket column 121 using control ontology 12 with moving sleeve, and sleeve is made to execute bolt tool assembly and disassembly operation； When the force of ratchet device 10 to be converted operates direction, user rotatably holds the steering turntable 14 of 11 top surface of seat, i.e., changeable The inner ring ratchet 112 of seat 11 is held by the latch engagement of 13 other side of clipping block, and then changes force operation direction；However, this one Ratchet device 10 is lacked in using upper with following：

1. the top surface of seat 11 is held since the steering turntable 14 of ratchet device 10 is assemblied in, when seat is held in the hand gripping of user 11, and with palm compresses steering turntable 14 and exert a force operation rotation when, hand easily occurs can connect accidentally in operation rotation process The case where moving the steering turntable 14 rotation, thus the force for changing ratchet device 10 operates direction, causes to should be force behaviour originally Make direction and but become actuation direction of dallying, so that user must rotate switching steering turntable 14 again, user is caused to operate Inconvenient missing.

2. hold the top surface of seat 11 since the steering turntable 14 of ratchet device 10 is assemblied in, lead to not in control ontology 12 or The upper space for holding seat 11 adds the set access slot of different function, and is only capable of being socketed using positioned at the socket column 121 for holding 11 lower section of seat Sleeve, and other driving instruments (such as tool bar) use that can not arrange in pairs or groups, must be with the dismountable bolt tool in large force side if encountering When, user is still only capable of causing so that hand imposes biggish strength and more arduously operates ratchet device 10 using limited merely Missing.
