Description

Speeder wrench

Technical field

The invention belongs to a kind of hand-operated tools, relate in particular to a kind of speeder wrench.

Background technology

Spanner is one of a kind of instrument that the most generally uses in the hand-operated tools; The operator can regulate use within the specific limits according to the workpiece of different specification size; The mode that traditional adjustable wrench and pipe vice great majority adopt tooth bar to cooperate with worm gear, adjustable wrench of making by this way and pipe vice need rotate worm gear to regulate the jaw folding frequently when the workpiece of rotation different size, and governing speed is slow; Skid easily, operate dangerous.

Summary of the invention

In order to solve the deficiency of existing adjustable wrench and pipe vice; The invention provides a kind of speeder wrench, this spanner has not only kept all functions of existing adjustable wrench and pipe vice, and can carry out jaw apace and regulate; Moving jaw can not be reversed phenomenon during rotational workpieces; Clamping is firm, easy damaged workpiece not, and handling safety is reliable.

Be to realize above-mentioned purpose, the present invention has adopted following technical scheme: a kind of speeder wrench, and said spanner is formed by pulling body, movable jaw, tooth piece, spring, cover plate, adjusting key pin, adjusting key, screw, position-limitting pin; The front end of pulling body is fixing spanner, and the rear end of pulling body is a handle, and fixedly the spanner inboard is the piece-holder face; Pull external side and fixedly be provided with teeth between spanner and the handle, the piece-holder face is arranged on the movable jaw, movable jaw clamping face top is provided with connecting through hole; This connecting through hole communicates with a tooth piece groove, and the movable jaw clamping face is faced fixedly spanner clamping face, sees through the connecting through hole that is positioned at movable jaw; Be enclosed within movable jaw to pull on the body from pulling body handle one end; Position-limitting pin is fixed in the pin spacing hole, makes the moving range of movable jaw be limited at position-limitting pin, the embedding of tooth piece band tooth one end is positioned at the tooth piece groove of the first end of Flexible spanner with fixedly between the spanner piece-holder face; Insert an end spring in the spring eye of tooth piece; Cover plate is pressed in the other end of spring, cover plate is fixed on the tooth piece groove top of said movable jaw, move movable jaw with screw; Under the effect of the tension force of spring, tooth piece teeth are accepted as unavoidable mutual interlock with the teeth of pulling on the body.

The side of said tooth piece is provided with through hole; Match with it; The both sides that are positioned at movable jaw tooth piece groove are respectively equipped with two elongated through holes; Adjusting key pin is passed the elongated through hole of through hole and said tooth piece groove opposite side of said elongated through hole and tooth piece from a side after, the link that adjusting key is pinned is connected with the end that adjusting key has connecting hole, stirs adjusting key along the opposite direction of spring tension; Tooth piece teeth are broken away from fully and pull the interlock of body teeth, the edge was passed adjusting key with the spring tension vertical direction movable jaw was moved pulling on the body teeth this moment.

Teeth on the shape of tooth piece teeth according to the invention and angle and the said fixedly spanner fit like a glove; When clamping and rotational workpieces; Movable jaw can be not voluntarily to moving away from fixing spanner clamping face direction, simultaneously, need not to stir said adjusting key; Directly promote movable jaw, it is slided to said fixedly spanner piece-holder face direction.

According to the invention, tooth piece groove communicates with the connecting through hole that is positioned at said movable jaw.

Speeder wrench of the present invention simple in structure regulates that to pull mouthful folding accurate rapidly, fundamentally solved skidding, prolonged the service life of workpiece, improved the security of operation.

Below in conjunction with accompanying drawing and embodiment the present invention is made further detailed description.

The specific embodiment

Embodiment 1:

A kind of speeder wrench embodiment, referring to Fig. 1 to Fig. 7, said spanner as shown in Figure 1 by pull body 1, movable jaw 2, tooth piece 3, spring 4, cover plate 5, adjusting key pin 6, adjusting key 7, screw 8, position-limitting pin 9 is formed; As shown in Figure 1, the front end of pulling body is fixing spanner 101, and the rear end of pulling body is a handle 102; Piece-holder face 103 is fixedly arranged on the spanner, as shown in Figure 3, piece-holder face 205 is arranged on the movable jaw; Like Fig. 1, shown in Figure 2, see through the connecting through hole 201 of movable jaw 2, said movable jaw is passed from handle 102 1 ends of pulling body 1; Push fixedly spanner 101 directions to, make it be higher than the pin spacing hole 104 that is positioned at said handle one side, position-limitting pin 9 is embedded in the said pin spacing hole; Stop said movable jaw to come off,, tooth piece 3 is had teeth 301 1 ends insert the tooth piece groove 202 that is positioned at said movable jaw like Fig. 4, Fig. 5, Fig. 6, shown in Figure 7 to an end of handle 102; One end of spring 4 is inserted in the spring eye 302 of said tooth piece, cover plate 5 is propped up the said spring other end, the circular hole 501 that sees through screw 8 said cover plate embeds the circular hole 204 that is positioned at said movable jaw tooth piece groove top; Said cover plate is fixed on the end face of said movable jaw tooth piece groove 202; Suitably move said movable jaw, make the teeth that are positioned at tooth piece groove 202 said tooth pieces and be positioned at said teeth 105 mutual interlocks of pulling on the body, like Fig. 6, shown in Figure 7; Adjusting key pin 6 is inserted said movable jaw tooth piece groove outside elongated through hole 203; After passing the elongated through hole of the through hole 303 that is embedded in said tooth piece groove internal tooth piece and said tooth piece groove opposite side, the link of said of bonding pin is had connecting hole one end with adjusting key 7 be connected, hold and clamp handle 102; Stir said adjusting key; The teeth 301 on tooth piece 3 surfaces are broken away from and the mutual interlock between said teeth 105 of pulling on the body fully, and the said movable jaw of push-and-pull this moment can make said movable jaw move around at said fixedly spanner piece-holder face and 9 of position-limitting pins; In the present embodiment; Because said facing that the body teeth pull body piece-holder face dorsad and the angle that the piece-holder face forms pulled is 45 degree, so can directly push away said movable jaw, and it is moved to said fixedly spanner piece-holder face direction.
