Abstract
An adjustable sleeve comprises an outer cylinder body, an inner cylinder body, a connecting body, a jaw component and two return springs. The inner cylinder body and the outer cylinder body can relatively slip in the axial direction. The jaw component is packed by the outer cylinder body and can be opened or closed under the action of the outer cylinder body. The adjustable sleeve has simple structure and can replace a set of sleeves with the different specifications for use, thereby reducing the number of accessories and facilitating the use.
Description
Technical field
The present invention relates to a kind of hand-held tool parts that are used to screw parts such as nut, relate in particular to a kind of adjustable sleeve.
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 different opening degrees, and the user needs spended time to remove to rotate worm gear; Perhaps in order to make the close easier of jaw, use the adjustable spanner of motorized, this spanner moves with the quickening caliper by battery-operated motor and regulates the opening and closing of jaw, 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.At different objects different sleeves will be installed during use, the target that the sleeve of different size is corresponding different may need repeatedly to change the sleeve of different size in the use.
Summary of the invention
Purpose of the present invention is exactly in order to solve the problem that above-mentioned prior art exists, a kind of adjustable sleeve that replaces one group of sleeve to use to be provided.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of adjustable sleeve, and it comprises:
Outer cylinder body;
Inner barrel is inlaid in the outer cylinder body, can do axially relative slip between inner barrel and the outer cylinder body;
Connector, one end and inner barrel are fixedly linked;
The jaw assembly, by the outer cylinder body big envelope interior, comprise upper jaw, lower jaw and tension spring, upper jaw links to each other with the other end of connector is rotatable by same bearing pin 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, the both sides of cylindrical shell inside and outside being separately positioned on, its front end links to each other with outer cylinder body by a bearing pin respectively, and the rear end links to each other with inner barrel by a bearing pin respectively.
The lateral surface of described upper jaw and lower jaw respectively is provided with an inclined-plane, and the front end of described outer cylinder 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 inner barrel, 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 inner barrel respectively.
The inner chamber that the bearing pin of described connection two back-moving spring front ends radially passes outer cylinder body respectively is connected the middle part of outer cylinder body, and two bearing pins form the gag lever post that outer cylinder body 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.
Two side external surface symmetries of described outer cylinder body are embedded with the inserted block that is used to improve frictional force.
Adjustable sleeve of the present invention is simple in structure, can replace the sleeve of a cover different size 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, Fig. 5, adjustable sleeve of the present invention comprises outer cylinder body 1, inner barrel 2, connector 3, jaw assembly 4 and two back-moving springs 5.
Two side external surface symmetries of outer cylinder body 1 are embedded with the inserted block 11 that is used to improve frictional force, and inwall is provided with and is used for the raised line that slides and to link to each other with inner barrel.Be arranged with two bearing pin 12, two back-moving spring front ends that radially pass the outer cylinder body inner chamber at the middle part of outer cylinder body and be connected on this bearing pin, two bearing pins also form the gag lever post that outer cylinder body moves forward and backward.
The rear end of connector 3 and inner barrel 2 are fixedly linked, and front end turns by bearing pin 6 with jaw assembly 4 and links to each other.
Jaw assembly 4 by outer cylinder body 1 big envelope interior, comprise upper jaw 41, lower jaw 42 and tension spring 43, upper jaw links to each other with the front end of connector is rotatable by same bearing pin 6 with lower jaw, and tension spring 43 is connected to provide between the upper and lower jaw and makes the open tension force of jaw; Upper and lower jaw is respectively equipped with the spring eye of opening to the inside, and the two ends of tension spring are connected in the spring eye of upper and lower jaw.
Two back-moving springs 5 are separately positioned on the both sides of inside and outside cylindrical shell, and its front end links to each other with outer cylinder body by a bearing pin 12 respectively, and the rear end links to each other with inner barrel by a bearing pin 22 respectively.The power that two back-moving springs 5 provide outer cylinder body to reset.
The present invention respectively is provided with an inclined-plane 411,421 at the lateral surface of upper jaw 41 and lower jaw 42, is provided with fore shaft 13 corresponding to above-mentioned inclined-plane at the front end of outer cylinder body 1, and jaw closed up when this fore shaft moved to the rear end on inclined-plane, as shown in Figure 3; Jaw opened up into maximum when this fore shaft moved to the front end on inclined-plane, as shown in Figure 4.
The operation principle of adjustable sleeve of the present invention can be described as follows in conjunction with Fig. 3, Fig. 4: as shown in Figure 3, when nature, adjustable sleeve is closed.Grasp outer cylinder body and move to the jaw direction, bit opens under the effect of tension spring gradually, and it is big that length between vices becomes, and the state of opening fully as shown in Figure 4.After target is inserted jaw, unclamp outer cylinder body, outer cylinder body promptly tightens up under the effect of back-moving spring and bites target, promptly turns and tighten target.Otherwise, can unclamp target.
