Abstract
The utility model discloses a multi-head ratchet wrench, which comprises a ratchet wheel, a handle and a shell, and is characterized in that: an inner cavity is arranged on the shell; the ratchet wheel is arranged in the inner cavity; a counter bore, a spring and a steel ball are arranged at the position of a notch of the ratchet wheel; the spring is arranged in the counter bore; and the steel ball is connected with the spring. In order to realize the versatility of the ratchet wrench and meanwhile effectively connect a nut, the multi-head ratchet wrench has the following characteristics: one shell and one ratchet wheel are respectively arranged at two ends of the handle; the shells are connected with the handle; and a polygonal hole is arranged on the ratchet wheel. In the multi-head ratchet wrench, a ratchet pawl is replaced by the spring and the steel ball, a forward/reverse steering mechanism does not need, and meanwhile, the effect that parts with many types, such as nuts and the like, can be operated by using only one multi-head ratchet wrench is achieved, thereby bringing great convenience to operators.
Description
Technical field
The utility model relates to the hand-operated tools that a kind of degree of tightness nut etc. uses, particularly a kind of multiheaded ratchet wrench.
Background technology
Present ratchet spanner generally comprises handle, is connected the shell of handle front end, ratchet and pawl.Because present ratchet spanner only is provided with a kind of ratchet, parts such as nut that therefore can only a kind of model of degree of tightness have brought great inconvenience for workman's the tightly work of unloading.As for will as described in (as Chinese patent ratchet spanner ZL200710022922.2), the use of ratchet spanner being restricted with hand adjustment joint, loose bolts along contrary commutation.
Summary of the invention
The purpose of this utility model be provide for the deficiency that solves above-mentioned technology a kind of can be in less scope of activities the multiple model of degree of tightness nut and can make things convenient for the multiheaded ratchet wrench of switch operation.
In order to achieve the above object, a kind of multiheaded ratchet wrench that the utility model is designed, it comprises ratchet, handle and shell, it is characterized in that on shell, being provided with inner chamber, ratchet is arranged in the inner chamber, indentation, there at ratchet is provided with counterbore, spring and steel ball, and spring is arranged in the counterbore, and steel ball is connected with spring.For the versatility that realizes ratchet spanner effectively links nut simultaneously, respectively be provided with a shell and a ratchet at the two ends of handle, shell is connected with handle, is provided with polygonal hole on ratchet.As preferably, and make ratchet realize effectively locking on inner chamber, described polygonal hole is quincunx hole, is provided with more than one breach and more than one counterbore on ratchet.
A kind of multiheaded ratchet wrench that the utility model provides, replaced ratchet with spring and steel ball, need not along reversing to mechanism, the parts such as nut that also reached multiple model are simultaneously only operated with a multiheaded ratchet wrench, therefore use to operating personnel to bring great convenience.
