Abstract

A ferrule type multi-purpose wrench is characterized in that: the utility model includes a handle and a connecting frame, the connecting frame includes an active joint, a connecting bar and a stable ring, the active joint and the stable ring are respectively fixed on two ends of the connecting bar, the stable ring is wrapped on the bar of the handle, the end of the handle bar is connected with a sleeve mechanism, the active joint and the sleeve mechanism are positioned on the same axis. The utility model sloves the problem that the bolt and the nut rotate at the same time, which has the advantages of simple operation, reasonable structure and simple processing.

Description

The bite type combination wrench

Technical field

The utility model relates to a kind of hand-operated tools, is specifically related to a kind of combination wrench.

Background technology

In our daily life, work, little repairing to bicycle, big maintenance to heavy duty machine tools equipment, when stubborn bolt and nut, the two rotates the phenomenon of (transfer) simultaneously all can to run into bolt and nut, has brought inconvenience to live and work, even, in the particularly new-type equipment of part military equipment, this phenomenon is apparent in view, has directly influenced operation and the use of army personnel to equipment.The approach that addresses this problem at present is to use two cover spanners, and this has increased the demand of instrument on the one hand, and on the other hand, a common people operates inconvenience, in some occasion even must two people operate simultaneously.

Summary of the invention

The utility model purpose provides the bite type combination wrench of a kind of set bolt in use, rotating screw cap.

For achieving the above object, the technical solution adopted in the utility model is: a kind of bite type combination wrench, comprise crank and link, described link comprises live head, connecting rod and stabilizing ring, head alive and stabilizing ring are individually fixed in the two ends of connecting rod, stabilizing ring is sheathed on the bar of crank, and the end of crank bar is connected with sleeve mechanism, and the described head of living is positioned on the same axis with sleeve mechanism.

In the technique scheme, can also include handle in described link, described handle is fixed in the connecting rod top; Handle can be fixed with connecting rod with screw, rivet etc., also can be structure as a whole with connecting rod.

In the technique scheme, between described sleeve mechanism and the crank bar quick detach engagement connection structure.Common various quick detach engagement connection structures, as spring hoodle structure, screw thread bayonet arrangement etc. all can be suitable for, and its objective is the sleeve of being convenient to change fast different size.

During use, at first select suitable sleeve for use, the head of adjusting on the link of living makes it cooperate with bolt head, clamping bolt is fixed it, and sleeve is entangled nut, shakes crank, sleeve rotates with crank, because the head of living has been fixed bolt, bolt can not follow nut to rotate.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage:

1. because the utility model is provided with link, be provided with head alive at an end of link, can set bolt, the problem of avoiding bolt and nut to rotate simultaneously;

2. link is socketed on the bar of crank by the stabilizing ring of an end, constitute integrative-structure, during operation after the head of living of link is fixed on the bolt, can operate in nut one side, the handle that is provided with on the link, make the operator can use fixedly connected the also direction of stabilizer sleeve of head of living on the other hand, another hand rotation crank, easy to operate;

3. the utility model is rational in infrastructure, and processing is simple.

Accompanying drawing 1 is the structural representation of the utility model embodiment one;

Accompanying drawing 2 is the cross-sectional schematic of embodiment one.

Wherein: [1], link; [2], the head of living; [3], connecting rod; [4], stabilizing ring; [5], handle; [6], crank; [7], sleeve mechanism; [8], bar; [9], spring; [10], steel ball.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: referring to attached illustrated in figures 1 and 2, a kind of bite type combination wrench, comprise crank 6 and link 1, the main body of described link 1 is a square rack, the top of square rack constitutes handle 5, the bottom is a connecting rod 3, the two ends of connecting rod 3 are fixed with respectively lives 2 and stabilizing ring 4, and the structure of described work 2 is consistent with the header structure alive of monkey wrench, and stabilizing ring 4 is sheathed on the bar 8 of crank 6, the end of crank bar 8 is the sleeve link, be provided with positioning ball 10 and spring 9 above, sleeve mechanism 7 can be inserted the sleeve link, and the steel ball 10 location engagings that are positioned, during use, described work 2 is positioned on the same axis with sleeve mechanism 7.

During use, select sleeve for use, be fastened on the end of crank bar according to the nut size, adjust the work openings of sizes on the link, it is cooperated with bolt head, clamping bolt is fixed it, the grasp handle location of head and bolt that guarantees to live on the other hand, another hand propelled crank makes sleeve entangle nut, shakes crank, sleeve rotates with crank, can change pine or change tight nut, because the head of living has been fixed bolt, bolt can not follow nut to rotate.

Embodiment two: a kind of bite type combination wrench, comprise crank and link, described link comprises connecting rod, live head and stabilizing ring, connecting rod is provided with handle, head alive and stabilizing ring lay respectively at the two ends of connecting rod, described header structure alive is consistent with the header structure alive of monkey wrench, stabilizing ring is sheathed on the bar of crank, the end of crank bar is the sleeve link, is provided with the screw fixed structure above, and sleeve mechanism can be inserted the sleeve link, locate by the screens groove, and fix by the screw fixed structure, during use, the described head of living is positioned on the same axis with sleeve mechanism.

Claims

1. bite type combination wrench, it is characterized in that: comprise crank [6] and link [1], described link [1] comprises live head [2], connecting rod [3] and stabilizing ring [4], head alive [2] and stabilizing ring [4] are individually fixed in the two ends of connecting rod [3], stabilizing ring [4] is sheathed on the bar of crank [6], the end of crank bar [8] is connected with sleeve mechanism [7], and the described head [2] of living is positioned on the same axis with sleeve mechanism [7].
