Abstract
An efficient continuous rotary hand screwdriver belongs to the field of hand tools. The existing hand screwdriver has the defect that the rotary direction needs to be controlled by hand in real time. A plurality of slot holes are formed in the radial direction of each of a front ratchet wheel clamp pawl and a rear ratchet clamping pawl; slot teeth of the front and rear ratchet wheel clamp pawls are respectively in meshing connection with the annular teeth at the longer ends of a front ratchet wheel gear and a rear ratchet wheel gear; the front and rear ratchet wheel clamp pawls are correspondingly embedded into mounting holes in large-diameter ends of a front ratchet wheel jacket and a rear ratchet wheel jacket and are clamped by snaps; a front reversing ring and a rear reversing ring are respectively sleeved on the front and rear ratchet wheel jackets by springs and steel balls; the small-diameter ends of the front and rear ratchet wheel jackets are respectively inserted into the mounting holes in a front handle and a rear handle; a fixing plate provided with a gear by a pin shaft is embedded in the rear ratchet wheel jacket; the gear is in meshing connection with the annular teeth at the short ends of the front and rear ratchet wheel gears; the rear end of a sleeve connection rod is inserted into the front handle, the front ratchet wheel gear and the rear ratchet wheel gear in sequence; the sleeve connection rod is provided with a snap spring and the snap spring is attached to the front end surface of the front ratchet wheel gear. The efficient continuous rotary hand screwdriver can realize the control on the continuous rotation of the sleeve connection rod in the same direction.
Description
Technical field
The utility model belongs to and revolves tool hand-held tool technical field, especially has pass with a kind of rotary-type hand-screw of high-efficiency and continuous that can realize directed continuous rotation manipulation.
Background technology
Tradition hand-screw tool comprises knife bar, sleeve extension rod, ferrule, pin and handle, the rear end of sleeve extension rod is packed on handle by ferrule, pin, during use, knife bar is inserted on the front end of sleeve extension rod, be convenient to the exchange of different knife bars, but such structure can only be by manipulating single direction of rotation with hand in real time, easily make operator produce fatigue, cause operating efficiency low.
Utility model content
The purpose of this utility model is exactly to overcome existing hand-screw tool to exist the defect that need manipulate in real time with hand direction of rotation, and a kind of rotary-type hand-screw tool of high-efficiency and continuous that can realize directed continuous rotation manipulation is provided.
For this reason, the utility model is by the following technical solutions: the rotary-type hand-screw tool of a kind of high-efficiency and continuous, is characterized in that: the rotary-type hand-screw tool of described high-efficiency and continuous comprises back handle, rear commutation circle, buckle, steel ball, spring, rear ratchet overcoat, gear, sleeve extension rod, jump ring, front hand grip, front commutation circle, front ratchet claw, front ratchet overcoat, front ratchet gear, fixed head, bearing pin, rear ratchet gear and rear ratchet claw
,before, rear ratchet claw be radially provided with several slotted eyes, front, the groove tooth of rear ratchet claw is respectively with front, the annular tooth of rear ratchet gear long end is connected with a joggle, front, before the corresponding embedding of rear ratchet claw, in the installing hole of rear ratchet overcoat bigger diameter end and be stuck with buckle, front, rear commutation circle passes through spring, before steel ball is set in, rear ratchet puts outward, front, before the miner diameter end of rear ratchet overcoat is inserted into respectively, in the installing hole of back handle, by bearing pin, cogged fixed head is installed and is inlaid in rear ratchet overcoat, gear and front, the annular tooth of rear ratchet gear short end is connected with a joggle, and the rear end of sleeve extension rod is inserted front hand grip successively, front ratchet gear and rear ratchet gear, sleeve extension rod is provided with jump ring, the front end face of ratchet gear before jump ring reclines, the tail end inwall close-fitting of sleeve extension rod tail end and rear ratchet gear, sleeve extension rod, just in aggregates whole hand-screw tool parts integration, is held front hand grip, before rotation like this, rear commutation circle, before making, rear commutation circle keeps same direction, current, before the projection of rear ratchet claw screws in, in the time of in the slotted eye of rear ratchet overcoat, front, the groove tooth of rear ratchet claw one side is respectively with front, the annular tooth of rear ratchet gear long end separately, all can realize to this side continuous rotation by bidirectional rotation back handle.
Use the utility model can reach following beneficial effect: the utility model use time, hold front hand grip, by rotation commutate enclose indicateing arm position, bidirectional rotation back handle all can be realized directed continuous rotation.
Accompanying drawing explanation
Fig. 1 is the structural representation of facing of the present utility model.
