Have the annular knurl line that makes things convenient for the user to regulate operation on the adjusting nut structure in the above-mentioned described working head jaw closing capacity fast adjuster.
The scalable pincers handle of above-mentioned described integral type is divided into the screw-type connection of being with damping material and is with the push button of slideway to be connected.
The screw-type of band damping material connects the pincers handle in the scalable pincers handle of above-mentioned described integral type, clamp about comprising handle, about pincers handle overcoat, left and right adjusting locknut and left and right sides lock washer, about the pincers handle place respectively about the conformal shape of pincers handle overcoat inside, about pincers handle overcoat and left and right adjusting locknut by being threaded, left and right adjusting locknut internal structure has the structure of placement left and right sides lock washer.
The push button of band slideway connects the pincers handle in the scalable pincers handle of above-mentioned described integral type, clamp handle about comprising, about pincers handle overcoat and left and right adjusting press-button structure, the left and right adjusting press-button structure is respectively by the LR-button end cap, the left and right adjusting bar, left and right sides spring, left and right sides spring cushion block and left and right sides guide pad constitute, the groove of placing left and right sides spring and helicitic texture are wherein arranged in the LR-button end cap and be threaded with the left and right adjusting bar, spring one end face in the left and right sides places the groove of LR-button end cap, the other end places the groove of left and right sides spring cushion block, clamp on the end face of handle about the bottom surface of left and right sides spring cushion block is butted on, the other end of left and right adjusting bar is threaded with left and right sides guide pad, becomes the adjusting press-button structure that constitutes one; About pincers handle inside have about pincers handle limit body and left and right sides limit body gathering sill structure; About pincers handle overcoat inside left and right sides overcoat gathering sill, left and right sides limit body spacing hole are arranged and the left and right sides structure of mounting hole of regulating button are installed; Under the non-accent state, about being butted on, the bottom surface of the left and right sides spring cushion block in the adjusting button clamps on the pommel face, the left and right sides limit body spacing hole of pincers handle overcoat about the left and right sides guide pad that is connected with the left and right adjusting bar is arranged in, about in the pincers handle about pincers handle limit body place respectively about the left and right sides limit body spacing hole of pincers handle overcoat; Wherein correspondence is the groove structure about both positions of left and right sides limit body gathering sill and left and right sides overcoat gathering sill.
Above-mentioned described ratchet-type step device is to be made of ratchet plate, ratchet and ratchet spring, wherein there is fixing hole to be connected with bearing pin on the ratchet plate with pincers handle fixing hole, ratchet is fixedlyed connected with the ratchet hole on the pincers handle with bearing pin, ratchet spring one end is connected with aperture on the ratchet, and the other end is fixedlyed connected with the spring eye bearing pin on the pincers handle.
Above-mentioned described working head is to be made of left and right sides binding clip, cover plate, left and right sides bearing pin and locating shaft, wherein left and right sides binding clip lower end have respectively left and right sides connecting hole respectively with about pincers handle connecting hole corresponding connection, left and right sides binding clip is connected with left and right sides bearing pin with the corresponding aperture of cover plate, and interposition is equipped with locating shaft and flexibly connects.
Above-mentioned each installing hole of described member is equal-sized through hole.
The operation principle of the utility model product is: the different demands during according to user jaw is clamped are regulated pincers handle length voluntarily.When work is carried out, continue to press the pressing tongs handle, ratchet on the ratchet in the ratchet-type step device can be stirred the gear teeth on the ratchet plate, this process is done step-by-step movement work, thereby drive working head work, because ratchet one end is connected with ratchet spring, can haul ratchet on the ratchet in the course of the work and prop up the gear teeth on the ratchet plate, prevent the appearance of locking tooth phenomenon.When work puts in place, continue firmly, thereby the gear teeth that ratchet on the ratchet can be withdrawed from the ratchet plate reach the nature off working state, work is finished.After working long hours, jaw has wear phenomenon, can not guarantee the closed size after jaw clamps, this is just by unclamping the trip bolt that links to each other with fast adjuster this device of quick adjustment voluntarily, closed size after making it satisfy the jaw clamping, tighten trip bolt, this adjustment process finishes.When the user has the change of big degree to the jaw clamping force, can promptly change the lever ratio of pincers handle by changing pincers handle length to jaw, satisfy the different demands of user to the jaw clamping force.
After the user regulates the position according to the demand of working head jaw closing capacity with fast adjuster, place in the eccentric adjusting hole with trip bolt to be locked.
When regulating adjusting nut, the eccentric adjusting rod structure can be done relative rotation around the eccentric adjusting hole, and its cylinder can prop up ratchet plate end face with the difference of the anglec of rotation, thus the closed size of adjustment working head jaw in various degree.When adjusting the position,, can satisfy user's demand by eccentric adjusting hole locking trip bolt.
The different demands of strength when the scalable pincers handle of integral type can satisfy the user jaw is clamped.When the strength when the user has pair jaw to clamp has different demand, can regulate pincers handle length voluntarily,, satisfy user's demand by changing pincers lever ratio handle and binding clip.
When the user has the different demand of pair jaw clamping force, will press the adjusting button and regulate pincers handle length voluntarily, at this moment by regulating the spring action button end cap in the button, adjusting rod and guide pad can be with pressure lateral movements in the pincers handle, the end face of adjusting rod can compress the distortion of pincers handle limit body makes it break away from the limit body spacing hole of pincers handle overcoat, this moment, guide pad can move along gathering sill, after the user regulates pincers handle length, unclamp the adjusting button, pincers handle limit body can return to nature, and can the nature playback enter in the limit body spacing hole of pincers handle overcoat, guide pad also can be owing to tight spring cushion block is given as security in the elastic force effect of spring automatically, locking pliers handle position, thus reach the effect of regulating pincers handle length.
The superiority of the utility model product is: 1, fast adjuster is simple to operate, easy to use, can regulate because the closing capacity error behind the clamping claw that the jaw wearing and tearing cause by trace; The different demands of strength were regulated pincers handle length voluntarily when 2, the scalable pincers handle of integral type can clamp jaw according to the user, thereby improved Leveraged rate, satisfied the requirement of user labour-saving.
