Abstract
The invention relates to an adjustable gun-type box spanner, which comprises a gun-type handle, a sleeve body, a connector, a tongs assembly, two return springs, and a push rod. The connector is nested in the sleeve body, the back end of the connector is fixedly connected with the gun-type handle, and the connector and the sleeve body can perform axial relative sliding. A pull rod shaft passes through the gun-type handle and the connector so as to be fixedly connected with the sleeve body, the back end of the pull rod shaft extends out of the gun-type handle, and the push rod can drive the sleeve body to move forwards and backwards. The tongs assembly is enveloped in the sleeve body and can open and close under the action of the sleeve body. The adjustable gun-type box spanner has a simple structure, can substitute the prior box spanner, can simplify the number of fitting parts, and is more convenient to use.
Description
Technical field
The present invention relates to a kind of hand-held tool of the parts such as nut that are used to screw, relate in particular to a kind of adjustable gun type socket wrench.
Background technology
The adjustable spanner of prior art generally has a worm-and-wheel gear, and the motion that is used for controlling moving caliper is to reach the various openings degree, and the user needs spended time to remove to rotate worm gear; Perhaps for make jaw near easier, use the adjustable spanner of motorized, this spanner moves and regulates the opening and closing of jaw to accelerate caliper through battery-operated motor, has saved the time of regulating jaw; More than two kinds of instruments all need some Mechanical Driven or transmission to realize regulatory function
The ratchet wrench of prior art has ratcher function, but it needs the supporting use of sleeve of one group of different size.Different sleeves will be installed to different objects during use, the corresponding different working object of the sleeve of different size possibly repeatedly changed the sleeve of different size in the use.
Summary of the invention
The object of the invention is exactly in order to solve the problem that above-mentioned prior art exists, a kind of adjustable gun type socket wrench to be provided.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of adjustable gun type socket wrench, comprise rifle formula handle, and also comprise:
Sleeve body;
Connector is nested in the sleeve body, and its rear end and rifle formula handle are fixedly linked, and can do between connector and the sleeve body axially to slide relatively;
The jaw assembly; By the sleeve body big envelope interior; Comprise upper jaw, lower jaw and tension spring, upper jaw links to each other with the front end of connector is rotatable through a bearing pin respectively with lower jaw, and tension spring is connected to provide between the upper and lower jaw and makes the open tension force of jaw;
Two back-moving springs are separately positioned on the both sides in connector and the sleeve body, and its front end links to each other with sleeve body through a bearing pin respectively, and the rear end links to each other with connector through a bearing pin respectively;
Push rod, it axially passes rifle formula handle and connector and sleeve body and is fixedly linked, and stretch out from rifle formula handle the rear end, and push rod can drive sleeve body and move forward and backward.
The lateral surface of described upper jaw and lower jaw respectively is provided with an inclined-plane, and the front end of described sleeve body is provided with the fore shaft corresponding to above-mentioned inclined-plane, and jaw closed up when this fore shaft moved to the rear end on inclined-plane, and jaw opened up into maximum when this fore shaft moved to the front end on inclined-plane.
Be arranged with two spring eyes that axially connect on the described connector, the inner of described two back-moving springs is separately positioned in this spring eye, and the bearing pin of described connection two back-moving spring rear ends radially passes the rear end that spring eye is connected connector respectively.
The inner chamber that the bearing pin of described connection two back-moving spring front ends radially passes sleeve body respectively is connected the middle part of sleeve body, and two bearing pins form the gag lever post that connector moves forward and backward.
Described upper and lower jaw is respectively equipped with the spring eye of opening to the inside, and the two ends of described tension spring are connected in the spring eye of upper and lower jaw.
Adjustable gun type socket wrench of the present invention is simple in structure, can replace conventional box spanner to use, and can simplify number of fitting parts, uses more convenient.

The specific embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, Fig. 3, Fig. 4, adjustable gun type socket wrench of the present invention comprises rifle formula handle 1, sleeve body 2, connector 3, jaw assembly 4, two back-moving springs 5 and push rod 6.
Two back-moving springs 5 are separately positioned on the both sides in connector and the sleeve body, and its front end links to each other with sleeve body through a bearing pin 8 respectively, and the rear end links to each other with connector through a bearing pin 9 respectively;
Push rod 6 axially passes rifle formula handle 1 and is fixedly linked by (through a cotter pilotage 10) with connector 3 and sleeve body 2, and stretch out from rifle formula handle the rear end, and push rod can drive sleeve body and move forward and backward.
The upper jaw 41 among the present invention and the lateral surface of lower jaw 42 respectively are provided with an inclined-plane 411,421; The front end of sleeve body 2 is provided with the fore shaft 21 corresponding to above-mentioned inclined-plane; Jaw closed up when this fore shaft moved to the rear end on inclined-plane, and jaw opened up into maximum when this fore shaft moved to the front end on inclined-plane.
The inner that is arranged with two spring eye 31, two back-moving springs 5 that axially connect on the connector 3 among the present invention is separately positioned in this spring eye, and the bearing pin 10 that connects two back-moving spring rear ends radially passes the rear end that spring eye is connected connector respectively.The inner chamber that the bearing pin 9 that connects two back-moving spring front ends radially passes sleeve body 2 respectively is connected the middle part of sleeve body, and two bearing pins 9 form the gag lever post that connectors move forward and backward.
The operation principle of adjustable gun type socket wrench of the present invention can combine Fig. 5, Fig. 6 to explain as follows: as shown in Figure 6, when nature, adjustable gun type socket wrench is closed.Withstand push rod with hand and move to the jaw direction, push rod drives sleeve body and moves forward, and bit opens under the effect of tension spring gradually, and it is big that length between vices becomes, and the state of opening fully is as shown in Figure 5.After target is inserted jaw, unclamp push rod, sleeve body promptly tightens up under the effect of back-moving spring and bites target, promptly turns and tighten target.Otherwise, can unclamp target.
