Abstract
The utility model relates to a pair of self-locking pliers which are used for the industry and the family. The self-locking pliers utilize the mechanical driving principle of a four-bar mechanism. The self-locking pliers which comprise an oscillating-type maxilla, a self-locking mechanism, a releasing mechanism, a regulating rod and a sectional type heterotype can work even if people can not continuously apply pressure. So the aims of multiple use and more functions of the pliers, labor saving, time saving and work efficiency improving can be achieved. The device can be also transplanted onto other work clamping tools.
Description
The invention belongs to the hand-operated tools of industry and family expenses.
Generally when reversing workpiece and cutting off wire, adopt hand with clamping gripping tongs or pipe wrench more.Hand can not be adjusted jaw with pincers, though gripping tongs can be adjusted jaw, just adjusts positions for two kinds, can not self-locking, pipe wrench can be adjusted jaw, but must constantly apply artificial coupling mechanism force when work, the ability self-locking, therefore, existing instrument efficient is low, and range of application is narrow, uses inconvenient.
The present invention at existing all class instruments, can not adjust jaw, can not self-locking and must constantly apply the shortcoming of artificial coupling mechanism force during work, and as technological improvement, develop and a kind ofly can adjust jaw, again can self-locking, also can produce the self-locking pincers of certain coupling mechanism force.One of them embodiment such as accompanying drawing (1).
Its accompanying drawing (1) is the schematic diagram of self-locking pincers, and 1 is maxilla among the figure, and 2 is the maxilla lock shaft, and 3 are extension spring, and 4 is upper handle, and 5 is adjusting lever, and 6 is lower handle, and 7 is release lever, and 8 for discharging lock shaft, and 9 is pole, and 10 is bolster, and 11 is the lower jaw lock shaft, and 12 is lower jaw.(a) section is a plane, and (b) section is tooth-like bent type, and (c) section is the sword type.
The present invention is absorbing domestic existing hand with on the advantage basis of pincers, gripping tongs and pipe wrench, develop a kind of self-locking pincers, its characteristics are to be provided with shuttle-type lower jaw, self-locking mechanism, relieving mechanism, the special-shaped jaw of adjusting lever and segmented has formed that to have jaw size adjustable, naturally locking, the multi-functional self-locking that discharges with the back clamps.
Self-locking mechanism of the present invention, form by adjusting lever (5), pole (9), lower handle (6), lower jaw (12), extension spring (3), one end of pole (9) is formed by bolster (10) or screw and lower handle (6) and is rotationally connected, the other end inserts in the open slot of upper handle (4), and can slide at it.One end of lower jaw (12) is formed by lower jaw lock shaft (11) or screw and lower handle (6) and is rotationally connected, the other end of lower jaw (12) is rotationally connected by maxilla lock shaft (2) and upper handle (4) composition, because last lower handle, lower jaw and pole have been formed quadric chain mutually, and give the reaction force that selects different jaw position control pole rotational angle and extension spring by adjusting lever and make its this mechanism produce auto-lock function.
Relieving mechanism of the present invention is by lower handle (6), release lever (7) and extension spring (3) are formed, release lever is connected on the lower handle (6) by discharging lock shaft (8) or screw, one end of extension spring (3) is connected on the lower jaw (12), the other end is connected on the upper handle (4), and when pressing the right-hand member of release lever (7), its left end is stirred pole (9), because the effect of extension spring drives the lower jaw rotation its workpiece is discharged.
Self-locking pincers of the present invention, the special-shaped jaw of equidistant relatively segmented is made at maxilla (1) and its jaw position of lower jaw (2).(a) section is a plane; (b) section is tooth-like bent type; (c) section is the sword type.Similar shape unskilled labourer part is the function of certain limit wire rod with cutting off diameter to make the self-locking pincers tighten not.
This self-locking clamps its operation principle: before work, at first adjust certain position by adjusting lever, promote pole, make its jaw open the angle suitable with the caught workpiece size.Then, compress lower handle, produce self-locking, just can carry out work, or turning of work piece, or cut off wire rod, overcome the working method that people constantly exert pressure when work.After the purpose of finishing the work, only need the light release lever that presses to make jaw break away from workpiece.
The present invention compared with prior art, the characteristics that not only have self-locking, release and multiple working conditions, but also realized when work people needn't constantly exert pressure can work characteristics, thereby reached pincers many clamp with one multi-functional, promptly time saving and energy saving purpose of increasing work efficiency again.The operation principle of this self-locking pincers also portable arrives on other the work card tool.
