Abstract
The utility model relates to a push-pull quick spanner, which is characterized in that a spanner body is provided with sliding hair clippers and a screw bolt. The sliding hair clippers are sheathed on the screw bolt, and the inside of the sliding hair clippers is provided with a screw bar or a spiral groove which is matched with the screw bolt. One end of the screw rod is connected with a driving bevel gear that is engaged with a driven bevel gear which is arranged on a nipper-opening screw rod; the sliding hair clippers are pushed or pulled along the wrench body; the screw rod is rotated through the matching of the sliding hair clippers and the screw rod. The driving bevel gear is also rotated, and the driven bevel gear which is engaged with the driving bevel gear is driven to rotate. The nipper-opening screw bolt is further rotated, and a movable jaw is opened and closed through a rack arranged on the movable jaw. The utility model has the advantages of convenient operation and saving operation time, and is suitable for operation by wearing gloves in winter.
Description
The utility model relates to spanner, belongs to hand-operated tools, is applicable to the mounting or dismounting of nut, bolt, pipe.
Present commercially available adjustable wrench, the switching armrest of jaw refers to twist screw rod and opens and closes, and skids easily, when especially industry such as oil is worn the gloves operation, opens and closes very inconveniently, and the while key-bolt often comes off.
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of and can operate easily, and it is convenient to open and close, plug-type quick open and close spanner easy to manufacture.
Plug-type speeder wrench of the present utility model, comprise wrench body, regular jaw on the wrench body, moving jaw is opened the pincers screw rod, the slip hairclipper is housed in the wrench body, screw rod, the slip hairclipper is enclosed within on the screw rod, has spiral bar or helicla flute in the slip hairclipper, match with screw rod, screw rod one end connects a drive bevel gear, and this drive bevel gear and the driven wheel of differential engagement of opening on the pincers screw rod push away or draw the slip hairclipper along wrench body, by cooperating of slip hairclipper and screw rod, make the screw rod rotation, drive bevel gear is rotated thereupon, drives the driven wheel of differential rotation that is engaged with, be further rotated out the pincers screw rod, open or close moving jaw by the tooth bar on the moving jaw.
Plug-type speeder wrench of the present utility model, simple in structure, use very conveniently, be applicable to any workplace, be particularly suitable for the workman and wear gloves winter and use, particularly make things convenient for the workman of industries such as oil, also be applicable to the special location of workpiece.
For introducing the utility model in detail, below in conjunction with description of drawings:
Fig. 1 is the structural representation of the broken section of plug-type speeder wrench of the present utility model.
Referring to Fig. 1, plug-type speeder wrench of the present utility model comprises wrench body 1, the regular jaw 2 on the wrench body 1, moving jaw 3, moving jaw 3 slides on wrench body 1, and tooth bar shape structure (identical with the adjustable wrench of prior art, as not to be shown specifically on figure) is arranged at moving jaw 3 bottoms.Regular jaw 2 and moving jaw 3 can adopt various versions to be applicable to nut, the tightening or unclamp of bolt or pipe, opening pincers screw rod 4 matches with moving jaw 3, one slip hairclipper 5 is housed in the handle of wrench body 1, slip hairclipper 5 slides on wrench body 1, have spiral bar or helicla flute in the slip hairclipper 5, slip hairclipper 5 matches with screw rod 6, screw rod 6 rotates in the handle of wrench body 1, an affixed drive bevel gear 7 on the top of screw rod 6, driven wheel of differential 8 engagements on drive bevel gear 7 and the screw rod 4, push away or draw slip hairclipper 5 along wrench body 1,, make screw rod 6 rotations by cooperating of slip hairclipper 5 and screw rod 6, drive bevel gear 7 is rotated thereupon, drive driven wheel of differential 8 rotations, be further rotated out pincers screw rod 4, finally open or close moving jaw 3 by the tooth bar on the moving jaw 3.
Consider the technological requirement of processing, and the convenience in assembling and the adjusting, open the inner of pincers screw rod 4 and make hollow hole, there is a spring 41 to be installed in the hole, the free end of spring 41 and pin 42 are close to, the outer end of opening pincers screw rod 4 connects a plug screw 43 that is screwed on the wrench body 1, adjusts the degree of depth that is screwed into of plug screw 43, and the driven wheel of differential 8 on the pincers screw rod 4 is cooperated very like a cork with drive bevel gear 7.
Have a slip pin 51 on the slip hairclipper 5, this slip pin 51 is pulled 11 groove 111 and is slided along being fixed on lid on the wrench body 1, and lid is pulled 11 and is fixed on the wrench body 1 by screw 12.
Wrench body 1 also can have at least one double offset ring spanner hole 13, also can make the function of hammer shape with additional hammer to the end of wrench body 1.
Drive bevel gear and screw rod 6 can be made into one, and also available spring collar 67 connects, and makes it and can not rotate relatively, can not slide relatively, and is same, and driven wheel of differential 8 can be made into one with opening pincers screw rod 4, also can be affixed by various structures.
The rotation of screw rod 6 in wrench body 1, the positioner 61 that can adorn a similar bearing in the handle of wrench body 1 is to strengthen its location.
