Description
Technical field
The present invention relates to a kind of hand-operated tools, specifically be a kind of ratchet screwdriver.
Background technology
Existing screwdriver provides great convenience to people's life, is mainly used in the fastening or screw that comes loose.Its structure of the modal screwdriver of prior art generally comprises screwdriver handle, screwdriver rod and driver bit, and screwdriver is, screwdriver rod and the driver bit formula that is fixed as one, this screwdriver in use, need to constantly loosen, tighten the action of palm, being beneficial to the position of palm in the easy application of force rotates, in the time loosening, tighten palm, driver bit easily departs from screw, and therefore operation is very inconvenient.
In order to address the above problem, it is CN201645375U as disclosed a Granted publication number on State Intellectual Property Office website that people have designed ratchet screwdriver, name is called the patent of invention of ratchet spanner, it comprises handle, knife bar, in handle, there is the cavity of a hollow, be plugged on and on the handle column wall on handle, offer two draw-in grooves, teeth respectively elastic card are inserted in above-mentioned two draw-in grooves, the tooth papillae of knife bar is housed and the relatively turnable fit in hole of handle post is connected, and on one end away from knife bar of tooth papillae, jump-ring slot is set, this jump-ring slot and be arranged on jump ring clamping on handle post so that axial limiting between tooth papillae and handle post, the outer rim latch of tooth papillae engages with teeth, in handle post periphery, be set with a commutation circle, the inside of described commutation circle is provided with two projections, two teeth offset with two projections separately, this ratchet spanner is in the time of parbuckle screw, and the action that does not need constantly to loosen, tighten palm just can complete the degree of tightness of screw.
But above ratchet spanner or common screwdriver dismounting get rusty or be connected firmly screw time, need the larger strength of expense just can pull down, therefore use comparatively inconvenience; Moreover, it uses function singleness, people usually will carry out dismounting screw by sleeve in the time of servicing machine, so just need to use the L shaped afterburning rod matching with sleeve, therefore people are in the time of servicing machine, except band screwdriver and sleeve, also to carry in addition afterburning rod, make like this to carry and use all comparatively inconvenience.
