As shown in the figure: 1. the tool rest comprises a tool rest body, 2 parts of a blade, 3 parts of a sliding groove, 4 parts of a sliding locking block device, 5 parts of a spring sheet, 6 parts of a bolt, 7 parts of a pressing sheet, 8 parts of a spring bump, 9 parts of a groove.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model discloses when concrete implementation, provide a novel instrument sword, including knife rest 1 and blade 2, 1 inside spout 3 that link up that is equipped with of knife rest, the scarf joint is equipped with sliding lock block device 4 in the spout 3, sliding lock block device 4 be close to 1 open-ended one end of knife rest with blade 2 cup joints, sliding lock block device 4 includes shell fragment 5, bolt 6, presses piece 7 and spring lug 8, it is located to press piece 7 the 3 outsides of spout just fix on shell fragment 5, spring lug 8 fixed connection be in inside shell fragment 5, bolt 6 is connected on shell fragment 5, bolt 6 with blade 2 cup joints, shell fragment 5 is close to the one end of blade 2 and is established to buckling to the direction of keeping away from blade 2.

A groove 9 is arranged on one side wall of the sliding groove 3.

The outer side end of the spring convex block 8 is arc-shaped, and the spring convex block 8 is matched and clamped with the groove 9.

One end of the elastic sheet 5, which is far away from the pressing sheet 7, is in contact with the opening of the tool rest 1 and then is bent in the direction far away from the tool rest 1.

The tool rest 1 and the sliding locking block device 4 are both made of stainless steel.

The utility model discloses a theory of operation is: the utility model discloses a novel tool knife conveniently pulls down blade, and simple structure, and use intensity is high, and at present, the blade slider of traditional tool knife loses easily, and traditional tool knife dismantles the blade very troublesome in addition, and ordinary knife rest steel part is stamping forming simultaneously, need handle through multiple processing, very numerous and complicated, to these circumstances, this novel tool knife, including knife rest 1 and blade 2, knife rest 1 is inside to be equipped with the spout 3 that link up, the scarf joint is equipped with sliding lock device 4 in the spout 3, sliding lock device 4 can slide in the spout 3, sliding lock device 4 be close to knife rest 1 open-ended one end with blade 2 cup joints, during the use, promotes sliding lock device 4 can drive blade 2 and move along spout 3, sliding lock device 4 includes shell fragment 5, bolt 6, According to rotor 7 and spring lug 8, be located according to rotor 7 the spout 3 outside just is fixed on shell fragment 5, promotes and can conveniently promote shell fragment 5 motion according to rotor 7, spring lug 8 fixed connection is in inside shell fragment 5, be equipped with recess 9 on one side wall of spout 3, spring lug 8's outside end is established to arc, when promoting according to rotor 7, shell fragment 5 moves along spout 3, and at this moment, compression and the realization that resets through spring among spring lug 8 cooperation joint recess 9 realizes blocking blade 2, and when using, blade 2's atress is not enough to make spring lug 8 compression break away from recess 9, guarantees to use stably, bolt 6 with the aperture of blade 2 tip cup joints, the one end that shell fragment 5 is close to blade 2 is established to buckling to the direction of keeping away from blade 2, shell fragment 5 keep away from according to rotor 7 one end with the square of keeping away from knife rest 1 after the opening contact of knife rest 1 To buckling, because blade 2 inlays in spout 3, blade 2 receives the restraint of the cell wall of spout 3 for blade 2 breaks away from bolt 6, thereby removes cup jointing of bolt 6 and blade 2, realizes dismantling blade 2, knife rest 1 and sliding lock piece device 4 all establish to stainless steel, feel thick and heavy, and its own weight can let the user better gripping knife rest 1, can also reduce the process of technology processing, increases life.
