Abstract
The invention discloses a multi-purpose falling preventing wrench. The multi-purpose falling preventing wrench comprises a handle, and chucks at two ends of the handle; a sliding sleeve which slides on the handle, and a stopping pin which is fixedly connected with the sliding sleeve are arranged at the upper part of the handle; the width of the stopping pin is not greater than the diameter of an inner cutting circle of a cap; a clamping opening is formed in one end of the stopping pin, at each chuck; the width of each clamping opening is equal to or slightly more than the diameter of a screw. The multi-purpose falling preventing wrench is simple in structure; the problem that a wrench slips away from the cap or a backup nut during screwing the cap and the nut can be effectively solved, and thus the bolt dismounting and mounting efficiency is greatly increased; the multi-purpose falling preventing wrench has a good popularization prospect.
Description
Technical field
The present invention relates to a kind of spanner, be specifically related to a kind of multiduty anti-loose wrench.
Background technology
Using common wrench when screwing bolt of long stem, the situation of nut slippage from spanner very easily occurring, as shown in Figure 1, affect operating efficiency, time serious or cause screw rod damage and cause staff to abrade.At present, also there are some anti-loose wrench, its anticreep principle arranges dismountable cap fall prevention on the chuck of common wrench, but the structure of this cap fall prevention and install more complicated and require higher precision, therefore cost is higher, and helpless for screwing of the standby mother on bolt of long stem.
Summary of the invention
The technical problem to be solved in the present invention is to provide the multiduty anti-loose wrench that a kind of structure is simple, cost is low.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of multiduty anti-loose wrench, comprises handle and the chuck being located at handle two ends; Handle upper portion is provided with the sliding sleeve that can slide and the backing pin be fixedly connected with sliding sleeve thereon, and the width of backing pin is not more than nut inscribe diameter of a circle; Backing pin is provided with jaws in one end of chuck, and the width of jaws equals or slightly larger than the diameter of screw rod.
Wherein, described backing pin is located at the one or both ends of sliding sleeve.
Wherein, the outer end of described backing pin is outwards expanded gradually and is formed trumpet-shaped enlarging gear.
Wherein, described backing pin is a pair symmetrically arranged pin.
Wherein, described chuck is plum-blossom chuck or opening chuck.
The beneficial effect adopting technique scheme to produce is:
Structure of the present invention is simple, efficiently solves and screws in nut and standby female process, and spanner, from the problem of slippage nut or standby mother, makes the efficiency installing and removing bolt greatly improve, has good promotion prospect.

Detailed description of the invention
As shown in Figure 2,3, the invention discloses a kind of multiduty anti-loose wrench, comprise handle 11 and the chuck 12 being located at handle 11 two ends, chuck 12 is plum-blossom chuck or opening chuck; Handle 11 top is provided with the sliding sleeve 4 that can slide and the backing pin 5 be fixedly connected with sliding sleeve 4 thereon, and backing pin 5 is located at the one or both ends of sliding sleeve 4, and the width of backing pin 5 is not more than nut inscribe diameter of a circle; Backing pin 5 is provided with jaws 6 in one end of chuck 12, and the width of jaws 6 equals or slightly larger than the diameter of screw rod; The outer end of backing pin 5 is outwards expanded gradually and is formed trumpet-shaped enlarging gear 7; Backing pin 5 is a pair symmetrically arranged pin.
As shown in Figure 4, before using anti-loose wrench driving screws of the present invention, first nut 2 is inserted in chuck 12, then promote sliding sleeve 4 to chuck 12, backing pin 5 is slided thereupon and blocks nut 2, enlarging gear 7 props up chuck 12, like this, in the process screwing nut 2, spanner can not slippage; When after having screwed of nut 2, sliding sleeve 4 and backing pin 5 are regained, spanner can depart from nut 2 easily.
As shown in Figure 5, before the standby mother using anti-loose wrench of the present invention to screw on bolt of long stem, first chuck 12 is entangled standby female 3 by nut 2, then sliding sleeve 4 is promoted to chuck 12, backing pin 5 is slided thereupon and makes jaws 6 clamp screw rod, like this, screwing in the process of standby female 3, spanner also can not slippage; When after standby female 3 screwed, sliding sleeve 4 and backing pin 5 are regained, spanner can depart from from screw rod easily.
