Abstract
The present invention relates to an adjustable spanner, particularly to an angle changing adjustable spanner with a locking device. The present invention is composed of a handle (1), a hexagonal hole (2), a screw gear (8), an adjustable spanner opening (9), a fixing spanner opening (10), etc. The present invention is characterized in that a lengthening rack bar (7) is arranged on the adjustable spanner opening (9), the angle of the wrench can be adjusted by the movement of the lengthening rack bar (7), the left lower side of the fixing spanner opening (10) is provided with a threaded hole (6), and the locking device composed of a hand wheel (3), a screw rod (4) and a press jaw (5) is arranged in the threaded hole (6). Compared with the prior art, the present invention has novel structure, convenient use, adjustable spanner angles (original 112 DEG is changed to 118.5 DEG) and wide moving range. The torque force of the spanner is enhanced when the operating angle is differently adjusted, and the labor saving effect is achieved. The spanner can not be loose when operated because of the arrangement of the locking device, the spanner is conveniently used, and industrial accidents can be reduced.
Description
[technical field]
The present invention relates to monkey wrench, specifically a kind of variable angle adjustable spanner that has locking device.
[background technology]
At present, the monkey wrench that occurs on the market is when clamping work pieces, at first rotate the spiral shell wheel, the spiral shell wheel drives the tooth bar that is engaged with and laterally moves, thereby make the Flexible spanner mouth and pull body generation clutch action, the angle of general head of the monkey wrench of this structure and body portion is 112 °, does not reach needed torsion at work sometimes.Common wrench also can change the A/F that originally regulated and the workpiece that slippage blocked because of the collision in pulling the workpiece process, be easy to have influence on user's safety.
[summary of the invention]
It is a kind of by strengthening driving end and the angle of body and the length of lengthening tooth bar that purpose of the present invention just is to provide, thereby the torsion when reinforcement spanner operating angle difference is pulled more reaches the labour-saving effect.Be provided with locking device specially at the back of spanner in addition, allow spanner when activity, not have to unclamp may, promptly use smoothly, can reduce again and cause industrial accident.
Design a kind of variable angle adjustable spanner for achieving the above object,, fixedly pull mouthful compositions such as (10) by handle (1), hexagon ring (2), spiral shell wheel (8), Flexible spanner mouth (9); It is characterized in that: Flexible spanner mouth (9) is provided with lengthening tooth bar (7), the mobile angle that can adjust spanner of lengthening tooth bar (7), the lower-left side of fixedly pulling mouthful (10) has screwed hole (6), is provided with the locking device of being made up of handwheel (3), screw rod (4), paw (5) in the screwed hole (6); The angle of the head A of spanner and the B of body portion is 118.5 degree; The top of locking device is provided with paw (5), the terminal handwheel (3) that connects of paw (5) connecting screw rod (4) screw rod.
The present invention compared with prior art, novel structure, easy to use, the spanner angle can be adjusted, and changes 118.5 degree into by original 112 degree, scope of activities is wide, the torsion when strengthening spanner operating angle difference and pulling reaches the labor-saving effect; The setting of locking device allow spanner when activity, not have to unclamp may, both used smoothly, can reduce the generation of industrial accident again.
[description of drawings]
Fig. 1. be sectional elevation of the present invention.
Fig. 2. be longitudinal section of the present invention.
Specify Fig. 1. be Figure of abstract.
Referring to Fig. 1: handle (1), hexagon ring (2), handwheel (3), screw rod (4), paw (5), screwed hole (6), lengthening tooth bar (7), spiral shell wheel (8), Flexible spanner mouth (9), fixedly pull mouth (10).
[specific embodiment]
Do further general introduction below in conjunction with accompanying drawing, handle (1), hexagon ring (2), handwheel (3), screw rod (4), paw (5), screwed hole (6), lengthening tooth bar (7), spiral shell wheel (8), Flexible spanner mouth (9), fixedly pull mouthful (10) and adopt metal material machining to make, the manufacturing technology of this product is very easy concerning this professional people.
When the handle of holding variable angle adjustable spanner (1), rotation spiral shell wheel (8) makes and adds mobile pull mouthful (9) of carry-over bar (7) drive to correct position, screw handwheel (3) and screw rod (4) conveniently, make screw rod (4) go up precession to making paw (5) compress lengthening tooth bar (7) at screwed hole (6).Flexible spanner mouth (9) can be shifted; Return screw rod (4) and take paw (5) out of otherwise unclamp handwheel (3), but this moment turn spiral shell wheel again, the openings of sizes of regulating Flexible spanner mouth (9), desired location.Hexagon ring mainly is in order more to utilize the space, does pulling of different hexagonal caps and establishes.
Claims (1)
1. variable angle adjustable spanner, by handle (1), hexagon ring (2), spiral shell wheel (8), Flexible spanner mouth (9), fixedly pulling mouthful (10) forms, Flexible spanner mouth (9) is provided with lengthening tooth bar (7), the mobile angle that can adjust spanner of lengthening tooth bar (7), the lower-left side of fixedly pulling mouthful (10) has screwed hole (6), is provided with the locking device of being made up of handwheel (3), screw rod (4), paw (5) in the screwed hole (6), it is characterized in that the head A of its spanner and the angle of the B of body portion are 118.5 degree.
