Description

A kind of multifunction test pencil
Technical field
The utility model relates to a kind of test pencil, specifically a kind of multifunction test pencil.
Background technology
The test pencil of prior art only has measuring voltage function, on-off function and miniature straight screwdriver 3 kinds of functions usually; and electrician is in routine inspection and simple maintenance debugging efforts; often also need to use the instruments such as Phillips screwdriver, small flashlight, electrician's knife; in routine work; often coming and going working site because leaving behind certain instrument above, making troubles to work.Special in high-altitude and operation in narrow space, use multiple types of tools that inconvenience can be caused to put and carry, sometimes also to drop generation casualty accident because of instrument high-altitude, the survey dateline of existing test pencil is mostly without any protection, be directly exposed in air, if operator's hand touches the metal survey dateline surface leaked outside because of carelessness and can cause danger in use, the ultimate principle of test pencil is that detection end touching is by measuring point, operating personnel grips hand-held housing, touch is exposed on the end face of handheld housing body afterbody outside test pencil bar simultaneously, take human body as earth conductor, after forming loop, indicator indicates according to conduction situation, but, be that earth conductor also exists potential safety hazard with human body, if false touch high-voltage charged body, electric shock accidents will be caused, jeopardize personal safety, for above problem, need to propose new technical scheme.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, long service life, and use safety, has the multifunction test pencil of test pencil, torch and electrician's knife function concurrently, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of multifunction test pencil, comprise the electrical test pen point, handle and the conduction foot piece that connect successively, described electrical test pen point comprises containment vessel, metal measuring head and spring, described containment vessel is cylindrical tube, the first spring retainer projection and containment vessel spacing preiection is provided with in containment vessel, metal measuring head is provided with the second spring retainer protruding, described spring housing is connected on metal measuring head and at the first spring retainer between protruding and the second spring retainer projection, described containment vessel spacing preiection is positioned at the second spring retainer and throws one's back out to the side of spring; Described handle front is provided with display screen, voltage measurement switch, break-make measurement switch and pilot lamp by being electrically connected; The described handle back side is provided with the blade support of band blade chute, arranges blade holder in blade chute, described blade holder is arranged the blade of band fixed orifice; Described conduction foot piece one end is fixedly connected with handle afterbody, and the other end wriggles and extends to free end, and free end end is exposed wire, and conduction foot piece center section is coated with insulating outer layer.
As further program of the utility model: described first spring retainer is protruding, the second spring retainer is protruding and containment vessel spacing preiection is all set to circular.
As the utility model further scheme: the end of described containment vessel is provided with ring-type LED group, and the end of containment vessel is also provided with rubber plug, rubber plug is provided with the through hole passed for metal measuring head.
As the utility model further scheme: described metal measuring head is connected with the testing circuit in handle.
As the utility model further scheme: described blade holder slides setting in blade chute, and blade holder is flexibly connected with blade chute.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the containment vessel connected by spring by one, realize the parcel to metal measuring head, when measuring by making containment vessel reclaim contracting outward to the extruding of electrical test pen point, the metal measuring head of electrical test pen point is stretched out measure measured object, when avoiding operation, operating personnel's false touch metal measuring head causes electric shock, containment vessel end is provided with rubber peel simultaneously, the oxidation that can effectively prevent dust moisture from producing electrical test pen point and corrosion, improve serviceable life and the security performance of test pencil, handle afterbody has additional conduction foot piece, operating personnel only by natural low potential objects such as conduction foot piece contact bodies of wall, need make power supply, test pencil, body of wall form galvanic circle, can either effectively measure, electric current can be avoided again by human body, thus ensure the safety of operator, ring-type LED group and electrician's knife are combined with test pencil bulk junction cleverly, make the utility model have the function of torch, electrician's knife and test pencil concurrently, more convenient to use.
