Abstract
The utility model provides a chuck wrench, including spanner stick and wrenching bar, wrenching bar includes pole body and head, its characterized in that, the head is equipped with and is used for the ejecting elasticity ejection mechanism with chuck wrench, elasticity ejection mechanism includes elastomeric element, elastomeric element the place ahead is equipped with the telescopic fore -set, elastomeric element and fore -set pass through the locating part to be fixed on wrenching bar. The utility model discloses chuck wrench can improve the security in the production working process through elasticity ejection mechanism automatic ejecting droing after the operation finishes, has eliminated unnecessary hidden danger.
Description
Technical field
The utility model relates to a kind of chuck handle.
Background technology
Chuck handle is the instrument of operation chuck, and chuck is to the clamping of workpiece and to unclamp be inserted by chuck handle to pull hole, is driven pull wheel and rotate by rotating spanner, and and then actuator disc silk, and make parcel drive jaw action to realize.Spanner is easy to after a procedure to pass into silence and pulls on wheel at chuck, and like this, when starting chucking work, when rotated, spanner will be thrown out of chuck, certainly will cause unnecessary accident.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of chuck handle, and pass into silence after can overcoming use the defect of to pull at chuck on wheel.For this reason, the utility model is by the following technical solutions:
A kind of chuck handle, comprise spanner rod and wrenching bar, wrenching bar comprises shaft and head, it is characterized in that, described head is provided with the elastic ejection mechanism for being ejected by chuck handle, described elastic ejection mechanism comprises elastomeric element, and described elastomeric element front is provided with telescopic fore-set, and described elastomeric element and fore-set are fixed on wrenching bar by locating part.
On the basis adopting technique scheme, the utility model also can adopt following further technical scheme:
Described elastic ejection mechanism is positioned at the side of described head.
Described elastic ejection mechanism is positioned at the center of described head.
Described locating part is sheathed and be fixed on outside described head.
Described locating part is fixed in described head.
Described fore-set rear portion is step-like, and described locating part blocks mutually with described fore-set back step shape and described elastomeric element and fore-set is fixed on wrenching bar.
Owing to adopting the technical solution of the utility model, the utility model chuck handle comes off by elastic ejection mechanism automatic ejection after end of operation, improves the security in production work process, eliminates unnecessary hidden danger.

Detailed description of the invention
Embodiment one, as shown in Figure 1, Figure 2, Figure 3 shows, the chuck handle that the utility model provides comprises spanner rod 1 and wrenching bar 2, wrenching bar comprises shaft and head 21, the operate portions of described wrenching bar head is four directions or six square toes, described head is provided with the elastic ejection mechanism ejected by spanner, and described elastic ejection mechanism comprises elastomeric element 5, and described elastic ejection mechanism is positioned at the side of described head.Described elastomeric element front is provided with telescopic fore-set 4, and described elastomeric element 5 and fore-set 4 are arranged on wrenching bar by locating part 3.
Described locating part 3 is sheathed and be fixed on outside described head, and described fore-set rear portion is step-like, and described locating part blocks mutually with described fore-set back step shape and described elastomeric element and fore-set is fixed on wrenching bar.
When using wrench operated, the head of wrenching bar inserts pulls hole, and fore-set top is to pulling wheel bottom, and toward the direction contracting in wrenching bar head, elastomeric element 5 is compressed; After end of operation, elastomeric element 5 will withstand outwards top and stretch, and be ejected by spanner and pull hole, simultaneously described elastomeric element and withstand recovery initial position.
Embodiment two, as shown in Fig. 4, Fig. 5, Fig. 6, the chuck handle that the utility model provides comprises spanner rod 10 and wrenching bar 20, wrenching bar comprises shaft and head 210, the operate portions of described wrenching bar head is four directions or six square toes, described head is provided with the elastic ejection mechanism ejected by spanner, and described elastic ejection mechanism comprises elastomeric element 50, and described elastic ejection mechanism is positioned at the side of described head.Described elastomeric element front is provided with telescopic fore-set 40, and described elastomeric element 50 and fore-set 40 are fixed on wrenching bar by locating part 30.
Described elastic ejection mechanism is positioned at the center of described head.Described locating part 30 is fixed in the endoporus of described head, and fore-set 40 and elastomeric element 50 are also in this endoporus, and described fore-set rear portion is step-like, and described locating part blocks mutually with described fore-set back step shape and described elastomeric element and fore-set is fixed on wrenching bar.
When using wrench operated, the head of wrenching bar inserts pulls hole, and fore-set top is to pulling wheel bottom, and toward the direction contracting in wrenching bar head, elastomeric element 50 is compressed; After end of operation, elastomeric element 50 will withstand outwards top and stretch, and be ejected by spanner and pull hole, simultaneously described elastomeric element and withstand recovery initial position.
The foregoing is only specific embodiment of the utility model; but architectural feature of the present utility model is not limited thereto; any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among protection domain of the present utility model.
