Abstract

The utility model relates to a manual tool which is used for fastening, connecting and disassembling. By rotating a regulating disc, a clamped type wrench and a clamping opening which is engaged with the wrench are driven to slide in radial direction along a connecting sleeve, and the working gap of the clamping opening can be changed to satisfy different dimensions of workpieces. Because the direction of the clamping opening is vertical to the direction of the handle under stress, the clamping opening can be extruded into a narrow space to work without influencing the stress of the handle. The clamped type wrench not only has the advantage of an adjustable wrench which has wide range of application, but also has the advantages of a socket wrench which can be operated in a narrow space.

Description

The clamped-in style box spanner

The utility model relates to a kind of hand-operated tools fastening, that connect, dismantle that is used for, especially for clamped-in style box spanner fastening, demounting bolt.

People are used for fastening, the spanner of demounting bolt can be divided into fork spanner and adjustable wrench, it is with strong points when fork spanner uses, easy to operate, adjustable wrench goes for the bolt of various different sizes, but existing adjustable wrench generally adopts two bayonet socket clamping bolts, the stressed irrational distribution of bolt, in addition, the space that needs when using adjustable wrench is bigger, and when the space around the bolt was narrow and small, adjustable wrench was often just powerless, and can only use box spanner, and box spanner pullover all is at the bolt of single size, needs when the bolt of different size uses frequently to change pulloverly, and operating efficiency is low.

The purpose of this utility model provides a kind of applied range, can be at the clamped-in style box spanner of narrow space work.

In order to achieve the above object, the technical scheme that the utility model provides is as follows: clamped-in style box spanner described in the utility model comprises handle and bayonet socket, handle is connected on the adapter sleeve, the bottom of adapter sleeve has the "T"-shaped groove that can hold bayonet socket, top is for holding the groove of adjustment disk, adjustment disk top has regulating handle, has helicla flute on the bottom surface, has on the end face of bayonet socket and the corresponding tooth bar of helicla flute; Bayonet socket is installed in the "T"-shaped groove on the adapter sleeve, and adjustment disk is installed in the groove on the adapter sleeve, and the tooth bar on the bayonet socket is meshed with helicla flute on the adjustment disk.

For the flexibility that improves use and the intensity of bayonet socket, handle can be designed to two-segment type and be connected on the adapter sleeve by bearing pin, and bayonet socket is designed to up big and down small trapezoidal-structure.

During use, rotate adjustment disk by the regulating handle on the adjustment disk, adjustment disk drives and the bayonet socket of the engagement of the helicla flute bottom it slides in "T"-shaped groove, and the gap of regulating bayonet socket is to adapt to the bolt of different size, and turning handle can precession or back-out bolt.Because handle is connected by bearing pin with adapter sleeve, so handle can be center rotation with the bearing pin on adapter sleeve, uses more convenient flexible, when handle rotates to the position vertical with adapter sleeve, with the first half bending 90 degree of handle, this moment, this spanner just became box spanner.

After adopting technique scheme, the size in the gap by regulating bayonet socket can adapt to the workpiece needs of different size, simultaneously, because the chucking direction of bayonet socket is subjected to force direction vertical with handle, bayonet socket can be put in narrow space work during use and handle stay the outside, play the effect of box spanner; The utility model adopts the bayonet socket chucking workpiece that can regulate, therefore not only is used in the workpiece of regular shape, also can be used for erose workpiece.

Further specify the utility model below in conjunction with drawings and Examples:

Fig. 1 is the partial sectional view of an embodiment of the present utility model;

Fig. 2 is the upward view of the adjustment disk among Fig. 1;

Fig. 3 is the partial sectional view of the adjustment disk among Fig. 1;

Fig. 4 is the front view of the bayonet socket among Fig. 1;

Fig. 5 is the vertical view of the bayonet socket among Fig. 1;

Fig. 6 is the right view of the bayonet socket among Fig. 1.

As shown in Figure 1, clamped-in style box spanner described in the utility model comprises handle 1 and bayonet socket 2, handle 1 is connected on the adapter sleeve 4 by bearing pin 3, the bottom of adapter sleeve 4 has the "T"-shaped groove that can hold bayonet socket 2, the quantity of bayonet socket 2 can be set at 3 or 4 as required, corresponding on the circumference of adapter sleeve 4, evenly distribute 3 or 4 "T"-shaped grooves, the top of adapter sleeve 4 is for holding the groove of adjustment disk 5; As Fig. 2, shown in Figure 3, adjustment disk 5 tops have regulating handle 6, have helicla flute 7 on the bottom surface; As Fig. 4, Fig. 5, shown in Figure 6, bayonet socket 2 is up big and down small trapezium structure, has on the end face and helicla flute 7 corresponding tooth bars 8; Bayonet socket 2 is installed in the "T"-shaped groove on the adapter sleeve 4, and adjustment disk 5 is installed in the groove on the adapter sleeve 4 and internal thread and bolt 9 by adapter sleeve 4 centers are connected on the adapter sleeve 4, and adjustment disk 5 can rotate in groove; Tooth bar 8 on the bayonet socket 2 is meshed with helicla flute 7 on the adjustment disk 5.

During use, promote regulating handle 6 and can make adjustment disk 5 rotations, drive bayonet socket 2 radially sliding along adapter sleeve 4 in "T"-shaped groove during adjustment disk 5 rotations with its engagement, changed gap between the bayonet socket 2 to adapt to the workpiece requirement of different size, in this sense, this clamped-in style spanner has the advantage of wide range of application of monkey wrench; Simultaneously, the folder mouth direction of this clamped-in style spanner is subjected to force direction vertical with handle 6, bayonet socket 2 can be put in narrow and small working space during use and not influence handle stressed, in this sense, this clamped-in style spanner has box spanner again can be in the characteristics of narrow space work; Handle 6 is connected with adapter sleeve 4 bearing pins 3, can the appropriate change handle 6 with the connection angle of adapter sleeve, thereby the duty of appropriate change handle is more flexible during use.
