Abstract
A wiper rocker compression nut assembly wrench belongs to a tool for screwing a nut. The main shortcoming of solving that operating personnel intensity of labour that current manual fixed box spanner exists is big, portable not convenient for. The utility model discloses a be equipped with the socket head of heavy groove, rotation axis, the handle that lower extreme and socket head are connected, the handle of saying passes through ratchet pawl mechanism and is connected with the upper end of rotation axis. The utility model discloses can make operating personnel need not repeatedly carry out the action of cover, pull out the cover barrel head at assembly windscreen wiper gland nut's in-process to alleviate operating personnel's intensity of labour. The utility model also has the advantages of simple structure, convenient carrying and convenient and labor-saving use.
Description
Technical field
The utility model belongs to the instrument of fastening nut, specifically a kind of windscreen wiper rocking arm clamp nut fitter spanner.
Background technology
The existing instrument that is used to tighten vehicle windscreen wiper rocking arm clamp nut mainly is manual fixed sleeve spanner, and its structure is that handle is connected with the collet head that has deep gouge by rotating shaft.Operating personnel are when using this manual fixed sleeve spanner, deep gouge with collet head is enclosed within on the vehicle windscreen wiper rocking arm clamp nut earlier, then with the manual mode rotary handle, behind the general half-twist (the singlehanded angle that can rotate) collet head is extracted from vehicle windscreen wiper rocking arm clamp nut, and again the deep gouge of collet head is enclosed within on the vehicle windscreen wiper rocking arm clamp nut (promptly getting back to original state) once more, repeat aforementioned operation, by repeatedly tightening vehicle windscreen wiper rocking arm clamp nut after the repeatable operation.Be the action that this manual fixed sleeve spanner needs operating personnel to overlap, pull out collet head repeatedly, not only greatly increased labor intensity of operating personnel, and owing to its each parts can not be dismantled and make handle not mate flexibly with collet head.
Summary of the invention
The purpose of this utility model be at above-mentioned deficiency provide a kind of simple in structure, be easy to carry, labour-saving easy to use windscreen wiper rocking arm clamp nut fitter spanner.
The utility model is achieved in that and comprises the collet head that is provided with deep gouge, rotating shaft, the handle that the lower end is connected with collet head, it is characterized in that said handle is connected with the upper end of rotating shaft by ratchet and pawl arrangement.
The deep-slotted chip breaker that said handle is provided with counterbore and is communicated with the inside side walls of counterbore, said ratchet and pawl arrangement comprises ratchet, ratchet, passes through the Location resilient piece that the compression spring is connected with ratchet, wherein, ratchet is fixed on the upper end of rotating shaft and is positioned at counterbore, and Location resilient piece is positioned at deep-slotted chip breaker.
The inwall of said counterbore is provided with circumferential circlip groove, and the upper end of said rotating shaft is with the circlip for hole that matches with circumferential circlip groove.
The lower end of said rotating shaft is connected with collet head by spring catch.
The utility model is by being provided with ratchet and pawl arrangement between handle and rotating shaft, the action that can make operating personnel in the process of assembling windscreen wiper clamp nut, need not overlap repeatedly, pull out collet head, thereby unnecessary operational motion in the elimination assembling process alleviates labor intensity of operating personnel.By spring catch is set, not only can be conveniently to maintenance of the present utility model, and can expand the scope of application of the present utility model.Circlip for hole can carry out axial limiting to rotating shaft.

The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
Embodiment: comprise the collet head 9 that is provided with deep gouge, the rotating shaft 2 that the lower end is connected with collet head 9, handle 1, handle 1 is connected by the upper end of ratchet and pawl arrangement with rotating shaft 2, wherein, the deep-slotted chip breaker 12 that the middle part of handle 1 is provided with counterbore 11 and is communicated with the inside side walls of counterbore 11, ratchet and pawl arrangement comprises ratchet 3, ratchet 4, by compressing the Location resilient piece 6 that spring 5 is connected with ratchet 4, ratchet 3 is fixed on the upper end of rotating shaft 2 and is positioned at counterbore 11, Location resilient piece 6 is positioned at deep-slotted chip breaker 12, the inwall of counterbore 11 is provided with circumferential circlip groove 10, the upper end of rotating shaft 2 is with the circlip for hole 7 that matches with circumferential circlip groove 10, and the lower end of rotating shaft 2 is connected with collet head 9 by spring catch 8 promptly becomes the utility model.
The course of work of the present utility model is: after being enclosed within the deep gouge of collet head 9 on the vehicle windscreen wiper rocking arm clamp nut 13, when forward rotation handle 1, because the effect of ratchet and pawl arrangement, rotating shaft 2 rotates with handle 1, and drive collet head 9 rotations, promptly tighten vehicle windscreen wiper rocking arm clamp nut 13; After handle 1 rotates to certain angle (as 90 °), but backward rotation handle 1, same because the effect of ratchet and pawl arrangement, rotating shaft 2 can not rotate with handle 1, be that collet head 9 can not drive 13 rotations of vehicle windscreen wiper rocking arm clamp nut, can tighten vehicle windscreen wiper rocking arm clamp nut by multi-pass operation.
