Abstract
The utility model discloses a multi-head changed type pick which belongs to hand instrument of labor. The utility model is composed of a half hollow truncated cone (1), support arms (4) arranged on the both sides of the half hollow truncated cone symmetrically, a matching pick (5), or (6), or (7) connected and fixed on the ends of the support arms (4), and a metal tube pick handle (2) is sheathed in the half hollow truncated cone (1). The utility model has the advantages of simple structure, a plurality of purpose, flexible and convenient use, raw material saving, efficiency improving, service life of a tool prolonging, etc.
Description
The utility model relates to a kind of hand instruments of labour, particularly relates to the improvement of a kind of hand with sharp pick.
Traditional hand is wide in the middle of being with sharp pick, in ellipse shape hole, wear a wood, both sides are that a metal material flat, a point constitutes.This pick in use owing to the long term wear of pick, have to as the refuse abandonment or melt down again by whole pick, and not only waste material reduces the utilization rate of pick, and wood influences work often fractureing in use.Moreover, because the pick shape is fixing, use also to be subjected to certain restriction.
The purpose of this utility model is will provide still can continue after a kind of pick experience wear to use, not only conservation but also can improve the comprehensive utilization ratio of pick and bull replacing formula easy to use makes things convenient for pick.
The purpose of this utility model is that a pick of suit in the supporting pick that is connected and fixed of support arm, the arm end by the setting of a semi-hollow frustum bilateral symmetry and the semi-hollow frustum is realizing.Its support arm and semi-hollow frustum one constitute, and the cross section of two support arms is " worker " font, the depression v notch v that respectively to be provided with a lower end in the end of two support arms be a chamfering.Connect supporting pick via this breach.Its supporting pick can be multiple shapes such as awl, spade, shovel, and this pick is provided with the breach that is meshed with support arm with the junction of support arm, and bolting.
The utility model has been owing to taked the removable pick of multiple shape, make this utility model have simple in structure a, pick how with, flexible, both conservation, raise the efficiency and have the advantages such as service life of prolongation instrument.
In conjunction with the accompanying drawings the technical solution of the utility model is described further:
Fig. 1 is the overall structure front view that bull replacing formula makes things convenient for pick;
Fig. 2 is the overall structure vertical view that bull replacing formula makes things convenient for pick;
Fig. 3, Fig. 4, Fig. 5 are respectively the supporting pick planar structure of awl, spade, the spade schematic diagrames that bull replacing formula makes things convenient for pick.
Make things convenient for pick by Fig. 1-bull replacing formula shown in Figure 5, be one down for real, on be the support arm 4 of the bilateral symmetry of the empty semi-hollow frustum 1 depression breach 3 that a cross section is set is a chamfering for " worker " font, end respectively are provided with a lower end, and corresponding supporting picks 5,6 or 7 and bolting of inserting of the depression v notch v by this support arm 43.Insert a metal tube pick 2 at semi-hollow frustum 1, bolting gets final product.
The utility model in use, can be as required or the pick degree of wear change supporting pick 5,6 or 7 at any time, the supporting pick 5,6 or 7 after the wearing and tearing can be processed to handle and continue to use.
Claims (3)
1, a kind of bull replacing formula makes things convenient for pick, and a pick that it is characterized in that this pick is the support arm (4) that is provided with by a semi-hollow frustum (1) bilateral symmetry, support arm (4) end is connected and fixed supporting pick (5), (6) or (7) and interior the suit of semi-hollow frustum (1) is (2) formation.
