Abstract
The invention provides a fall-prevention wrench which comprises a wrench body and a clamping plate. The head part of the wrench body is designed to be provided with a bayonet structure. An arc side is designed to be arranged on the bayonet structure. A semi-circle groove is designed to be formed in the clamping plate. The clamping plate adheres to the head part of the wrench body. The semi-circle groove of the clamping plate is concentric with the arc of the bayonet structure. The directions of the openings of the clamping plate and the bayonet structure correspond to each other. The fall-prevention wrench is simple in structure, convenient to use, not prone to falling when being used for screwing, higher in assembling efficiency and capable of being supported by the clamping plate when a bolt or a nut is detached and preventing the bolt or the nut from falling.
Description
Technical field
The present invention relates to spanner technical field, be specifically related to a kind of anti-sticking and fall spanner.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is conventionally shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist bolt or nut and hold opening or the trepanning of bolt or nut.The of a great variety of spanner can be divided into double (end) wrench, combination wrenches, shfting wrench etc., the opening of these spanners all runs through conventionally up and down for easy to process, in the time twisting bolt or nut, must keep the head of spanner and bolt head or nut place at grade with hand like this, when using spanner, people accidentally move along thread spindle, just likely make spanner depart from bolt head or nut, people's mode of just having to is again placed spanner and is bothered very much like this.And people are in the time using spanner removable screw or nut, in the time of bolt or the unexpected thread separation of nut, stressed unexpected conversion, bolt or nut are very easy to drop.
Summary of the invention
For above problem, the invention provides and a kind ofly carry out spacing anti-sticking and fall spanner breaking while turning effectively double thread head and nut.
The technical solution adopted for the present invention to solve the technical problems is: this anti-sticking falls spanner and comprises wrench body, clamp; The spanner partial design of described wrench body has bayonet arrangement, in described bayonet arrangement, is designed with arc-shaped edges, on described clamp, is designed with semi-circular groove, and described clamp is attached to the spanner part of described spanner; The circular arc concentric of the semi-circular groove of described clamp and described bayonet arrangement, and the opening direction correspondence of the two.
As preferably, the spanner part of described clamp and wrench body is hinged.
As preferably, described wrench body is double (end) wrench structure or combination wrenches structure or shfting wrench structure.
Beneficial effect of the present invention is: this anti-sticking falls spanner and can be used for tighting a bolt or nut, also can be used for twisting off bolt or nut.In the time tightening, the top that the clamp that this anti-sticking falls spanner is placed on bolt head or nut just in time covers the head of bolt or nut, and people are limited above spanner in the time twisting bolt or nut downwards like this, just can not fall down; Unscrewing when dismounting, the clamp that anti-sticking falls spanner is placed on the below of bolt head or nut, limited below spanner in the time upwards twisting bolt or nut like this, can up not run away.This spanner simple in structure, easy to use, is difficult for when spanner turns taking off, and efficiency of assembling is higher, when demounting bolt or nut, has holding of clamp simultaneously, can prevent that bolt or nut from dropping.
Accompanying drawing explanation
Fig. 1 is the structural representation that this anti-sticking falls spanner.
Fig. 2 is the structural representation of this anti-sticking when falling spanner and tighting a bolt.
Fig. 3 is the structural representation of this anti-sticking when falling spanner and twisting off bolt.
The specific embodiment
Below in conjunction with embodiment, the present invention is further described:
As shown in embodiment in Fig. 1, this anti-sticking falls spanner, and it comprises wrench body 1, clamp 2; The spanner partial design of described wrench body 1 has bayonet arrangement 11, in described bayonet arrangement 11, is designed with arc-shaped edges, on described clamp 2, is designed with semi-circular groove 21, and described clamp 2 is attached to the spanner part of described spanner; The semi-circular groove 21 of described clamp 2 and the circular arc concentric of described bayonet arrangement 11, and the opening direction correspondence of the two.Described wrench body 1 is double (end) wrench structure or combination wrenches structure or shfting wrench structure.Described wrench body 1 adopts double (end) wrench structure in this embodiment, and its two ends are all designed with clamp 2 structures.
This anti-sticking falls spanner and is mainly used to tighten hex bolts or nut, also can be used for twisting off hex bolts or nut.In this embodiment to twist bolt 3 as example.As shown in Figure 2, tighting a bolt 3 o'clock, the clamp 2 that this anti-sticking falls spanner is placed on bolt 3 head tops and just in time the head of bolt 3 is covered, and people are limited above spanner 1 in the time twisting bolt 3 downwards like this, just can not fall down.As shown in Figure 3, in the time unscrewing demounting bolt 3, the clamp 2 that anti-sticking falls spanner is placed on 3 belows of bolt, limited below spanner in the time upwards twisting bolt like this, can up not run away.This spanner simple in structure, easy to use, is difficult for when spanner turns taking off, and efficiency of assembling is higher, when demounting bolt 3, has holding of clamp 2 simultaneously, can prevent that bolt 3 from dropping.
As shown in Figure 1, described clamp 2 is hinged with the spanner part of wrench body 1.People also can break described clamp 2 to the inside like this, this anti-sticking is fallen to spanner and use as common spanner.In order to guarantee that clamp 2 has enough resistances while rotation, can between hinged of clamp 2 and wrench body 1, add rubber layer, can effectively guarantee that like this clamp 2 has enough resistances while rotation, clamp 2 just can arbitrarily not rotate like this, simultaneously rubber layer also can completely cut off hinging rotary face and water, plays antirust effect.
