Abstract
A structure of ratchet and junction comprises a driving head, a control loop, four clamp blocks, a ratchet and a cap head. The back end of the driving head is connected within a handle. The control loop is combined with the cap head and coats the driving head, four clamp blocks and a ratchet loop. The driving head has two containing spaces, each of which contains two clamp blocks. The two clamp blocks respectively have a spring used to bunt each other. The control loop has four convex poke rods. The poke rods toggle the two diagonal clamp blocks by turning the poke rods of the control loop in order to make the two diagonal clamp blocks off from the clamp to the ratchet loop. The other two diagonal clamp blocks bunt in the ratchet loop and, as a consequence, do the three-way control of counterclockwise and clockwise braking to reach the aims of double-clamp, increasing twisting force and no escape. The structure has large twisting force, balance and no inclination. The structure can clamp the ratchet indeed and make the ratchet not to escape. The structure adopts an extension type driving rod structure and can adjust the length of the driving rod. The structure is flexible and convenient to use.
Description
[technical field]
The structure of a kind of ratchet of the utility model and joint, relevant with ratchet tool, more detailed it, refer to especially the structure of a kind of ratchet and joint belong to ratchet tool.
[background technology]
As everyone knows, the clamping structure of ratchet is applied to hand-held tool, can drive workpiece rotates, can control its counterclockwise, clockwise unidirectional rotation or idle running, very convenient, as shown in Figure 1, be the generalized section of known box socket set, with 2 starts of a knob 1 control one poke rod, poke rod 2 has the spring 3 of elasticity, poke rod 2 is passed sour jujube piece 4 and is done unidirectional inclination and be equipped in ratchet 5, making drive rod 6 do unidirectional rotation, and drive workpiece, this is the box spanner that generally uses, the torsion of right its driving is still big inadequately, often has the facts of escape to take place;
As Fig. 2, shown in 3, it is the mode that known ratchet structure develops into the blocking bar, mainly contain a control loop 11, one ratchet ring 12, one drive rod 13 and two blocking bars 14,15, this blocking bar 14,15 are ㄩ type body, one side is positioned at control loop 11, side is positioned at ratchet ring 12 in addition, replaced by spring 16, and control loop 11 has two grooves 111,112 can supply blocking bar 14 respectively, 15 support into, this drive rod 13 has a spring 131 and steel ball 132, but steel ball 132 elasticity are butted on three locating slots 113 in the control loop 11,114, in 115, change (clockwise with the control of making syllogic, counterclockwise or idle running), utilize control loop 11 with the action of contracting or stretching out in a blocking bar 14 (or the blocking bar 15) work, in when contracting then blocking bar 14 be not stuck in ratchet ring 12, when stretching out then blocking bar 15 be stuck in ratchet ring 12, exchange with this and do clockwise, counterclockwise or the action of idle running;
Yet, the spring 16 of the blocking bar 14,15 of this two ㄩ type is to be positioned at the centre position, often there is the unbalanced situation of blocking bar 14,15 inclinations to take place, in case a blocking bar 14 (15) imbalances are arranged, and then the action of blocking ratchet ring 12 is uncertain, also there is the escape situation to produce, though two blocking bars 14,15 are arranged, but during action, have only 14 (15) effects of a blocking bar, its torsion is still big inadequately;
[novel content]
The structure of a kind of ratchet of the utility model and joint, its objective is provides four (two groups) clamping blocks, do the blocking of subtend,, provide clamping block to increase its double torsion, be able to balance, do not tilt, and can be equipped in ratchet really, not escape, the structure of extension type drive rod is provided, can adjusts drive rod length.
The structure of a kind of ratchet of the utility model and joint, it includes:
