Description

Fast spanners wrenches and pipe twist

The utility model belongs to hand tools, particularly a kind of spanner and pipe wrench of energy quickly opening and closing.

Existing spanner and pipe wrench all are that employing is regulated worm screw or nut, made and pull mouth, jaw folding.By constantly adjusting, could effectively screw or unclamp workpiece, such adjustment generally needs more than four times and even tens of times, causes inefficiency, wastes time and energy.

The purpose of this utility model is to provide a kind of spanner and pipe wrench of energy quickly opening and closing.

Its technical scheme is: a kind of fast monkey spanner, by pulling body, pulling mouthful, regulate worm screw and form, one groove is axially arranged on worm screw, the shape of the shape of groove and plate mouth lower gear rack is complementary, pull body top vicinity and pull mouthful the place and have and the corresponding graduation mark of standard nut opposite side dimension series, pulling a mouthful lower end has a reticle;

Pulling has a projection on the mouth, pull body one end correspondence and pull the mouth rack place one screw is arranged, and the semi-hollow screw of shooting property cock body in being rotary with in the screw prevents to pull and mouthful is free to slide in worm screw is slotted, and pulling end of body has a spacer pin.Worm screw one side has breach.

A kind of fast monkey spanner, by pulling body, pulling and mouthful form, open a groove in the middle of pulling mouthful lower end, be equipped with in the groove that tooth is pulled, loose piece, the loose piece two ends are connected with the spring that is fixed on the groove sidewall, the loose piece bottom has with tooth pulls the tooth that is meshed, and tooth is pulled upper and lower side respectively to be had and loose piece and pull the tooth that body is meshed, and pulls chute cross sectional shape on the body and tooth and pulls cross sectional shape and be complementary.

There is a shifting block at said loose piece middle part, and pulling body chute end has a spacer pin, and pulling a mouthful end has the groove that is complementary with alignment pin.

Pulling on the lateral surface of body upper hopper chute has and the corresponding graduation mark of standard nut opposite side dimension series, pull have on the mouth one with the corresponding reticle of graduation mark.

A kind of speeder wrench, by pulling body, pulling and mouthful form, one opening is arranged at the chute bottom of pulling body, pull and be fixed with eccentric stiffener on the body, eccentric stiffener is made up of eccentric wheel, eccentric shaft, pad and handle, pull mouthful and the eccentric wheel of eccentric stiffener between a panel is arranged, pull mouthful bottom and the opening of panel bottom chute contacts.

Pulling body chute end has a spacer pin, and pulling has the groove that cooperates with spacer pin on the mouth, and pulling has the projection of stirring usefulness together on the mouth.

A kind of fast pipe twist is made up of caliper, binding clip, pincers dental lamina, adjusting nut, respectively has an axial groove on the relative both sides of adjusting nut endoporus, at the afterbody of binding clip one spacer pin is arranged.

On the top of caliper one screw is arranged, be rotary with the semi-hollow screw of flexible cock body in the screw, have on binding clip and the corresponding graduation mark of standard tube outer diameter series, the caliper left end has the reticle that cooperates demonstration with graduation mark.

Adopt the spanner or the pipe wrench of above-mentioned several structures, can quickly opening and closing, reach needed position, do not need again through repeatedly regulating, time saving and energy saving, operating efficiency significantly improves.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 8 is the adjusting nut schematic diagram of embodiment 4;

Embodiment 1: have one and pull the arc groove 5 that mouthful 1 tooth portion matches among Fig. 1,2 on worm screw 3, pull mouthful 1 and can slide in groove 5.Pull and be carved with on the body 2 and the corresponding graduation mark 6 of standard nut opposite side dimension series, pull to have on mouthful 1 and cooperate the reticle 7 that shows usefulness, when work, can pull mouthful 1 and slide into desired location fast by making shown in the graduation mark with graduation mark 6.Pulling has a projection 4 on the mouth, pull mouth in order to stir.Pull on the body 2 correspondence and pull the mouth rack place one hole is arranged, be rotary with half hollow screw 8 in the hole, be plugged with a rubber tip in the screw hollow parts, in groove, be free to slide in order to prevent to pull mouthful 1.End has a spacer pin 9 on the body 2 pulling, and prevents to pull mouthful 1 from pulling landing on the body.To pull in use mouthful directly dial to desired location after, suitable rotary worm more just can be to workpiece work.One small gap 10 is set, in order to grasp the angle of worm screw on worm screw 3.

Embodiment 2: among Fig. 3,4, pull mouthful 1 bottom and have a groove, tooth plate 11, loose piece 12 are arranged in the groove, spring 13 is housed in the groove two side, have on the body 2 and the corresponding graduation mark 6 of standard nut opposite side dimension series pulling, pull to have with graduation mark on mouthful 1 and cooperate the reticle 7 that shows usefulness.Have with tooth in loose piece 12 lower ends and to pull 11 teeth that are meshed, tooth is pulled 11 upper and lower sides respectively to be had with loose piece 12 and pulls the tooth that body 2 is meshed.There is a shifting block 14 at loose piece 12 middle parts, and pulling body chute end has an alignment pin 15, and pulling a mouthful end has corresponding with it groove 16.

When using this kind spanner, stirring shifting block 14 will pull mouthful 1 according to the size of nut shown in the graduation mark and directly push desired location, decontrol shifting block 14 then, rely on the effect of both sides spring to make alive fast 12 to get back to original position as shown in Figure 3, tooth was pulled with the tooth of pulling body 2 and was meshed this moment, make and pull mouthful 1 and maintain static, can operate workpiece.Need move back and pull mouthful 1 o'clock, stir shifting block 14 and make to pull and mouthful back out.

Embodiment 3: pulling body 2 chutes bottoms among Fig. 5,6 has an opening, pulls to be fixed with an eccentric stiffener of being made up of eccentric wheel 17, eccentric shaft 18, pad 19 and handle 20 on the body, bottom chute and between the eccentric wheel panel 21 is arranged.Pulling body 2 ends has a spacer pin 22, and pulling mouthful 1 end has groove 23 with matching, prevents to pull mouthful 1 from pulling landing on the body 2, and pulling has projection 24 on the mouth, is used for stirring pulling mouth.

When using this kind spanner, when eccentric wheel 17 during in the centre position, pull mouthful 1 and panel 21 between can slide, stir projection 23 and can make and pull mouthful 1 and reach desired location.Then turning handle 20, make panel and pull between the mouth and rely on frictional force locking, can operate workpiece.

Embodiment 4: shown in Fig. 7,8, respectively have the groove 26 of a between centers on the relative both sides of adjusting nut 25 endoporus, binding clip 27 ends have a spacer pin 28.On the top of caliper one screw is arranged, be rotary with half hollow screw 29 in the screw, screw 29 hollow end are plugged with rubber tip, prevent that binding clip is free to slide.Have on binding clip and the corresponding graduation mark of standard tube outer diameter series, the caliper left end has the reticle that cooperates demonstration usefulness with graduation mark.

When using this pipe wrench, make binding clip 27 aim at the groove 26 of adjusting nut 25, directly binding clip 27 is slided into desired location, rotate adjusting nut then slightly, binding clip is fixed, can operate.
